The Snake Bit This Man Hundreds of Times—Now His Blood Saves Lives.

Tim Friede has endured hundreds of snake bites. Presently, researchers are analyzing his blood with the aim of developing more effective snake bite treatments.

Friede has a long-standing fascination with reptiles and other venomous creatures. He used to milk scorpions and had a collection of dozens of snakes at his home in Wisconsin.

To protect himself from snake bites and satisfy his “simple curiosity,” he started injecting himself with small doses of snake venom, gradually increasing the amount to build his tolerance before allowing a snake to bite him.

“It was very frightening at first,” Friede said. “But the more you do it, the better you become at handling it, and the more comfortable you get.”

While no healthcare professional would endorse this practice, experts indicate that his approach sheds light on how the body functions. When the immune system encounters snake venom, it produces antibodies that can counteract the venom. If exposed to a small quantity, the body might respond before being overwhelmed, and prior exposure can lead to quicker reactions to larger doses.

For nearly two decades, Friede has endured snake bites and self-injections, yet he still keeps a fridge stocked with venom. In a video on his YouTube channel, he showcases the prominent fang marks on his arms from black mamba, taipan, and water cobra bites.

“I essentially wanted to test the boundaries of life and death as much as possible,” he stated.

In addition, Friede sought to contribute to science. He reached out to numerous scientists, requesting studies on the tolerance he had developed.

According to the World Health Organization, approximately 110,000 people die from snake bites annually. Developing antivenoms is both costly and challenging, often requiring large mammals like horses to produce antibodies through venom injections. These antivenoms tend to be effective against only specific snake species and can cause adverse reactions due to their non-human origin.

Upon learning about Friede, Peter Kwon from Columbia University remarked, “Oh, wow, this is quite extraordinary. He is a uniquely special individual with remarkable antibodies developed over 18 years.”

In a publication in the Journal Cell on Friday, Kwon and collaborators shared insights on what Friede’s unique blood can accomplish. They have identified two antibodies capable of neutralizing venom from multiple snake species, aiming to create a treatment that could eventually provide broad protection.

This study is in its early stages—antivenoms are currently tested only on mice, with years needed before human testing can commence. While their experimental treatments show promise for certain snake categories, including mambas and cobras, they are less effective against vipers.

“Despite the potential, there is still much work to be done,” noted Nicholas Casewell, a snakebite researcher at the Liverpool School of Tropical Medicine, in an email. Casewell was not part of the recent study.

Friede’s journey has not been without challenges. He mentioned that a bad snake bite resulted in part of his finger needing amputation, and some severe cobra bites sent him to the hospital.

Friede is currently working with Centivax, which is developing a treatment, and he is hopeful that his 18-year journey might someday lead to a lifesaving solution for snake bites. However, his advice for those inspired to follow his path is straightforward: “Don’t do this,” he cautioned.

NASA’s Proposed 2026 Budget Cuts $6 Billion, Mainly Impacting Science Programs

On Friday, the White House unveiled a budget proposal outlining significant reforms at NASA as part of its initiative to secure $163 billion in federal funding.

The suggested reductions include a nearly 25% cut, translating to over $6 billion, from NASA’s budget. The most substantial decreases target the agency’s Space Science, Earth Science, and Mission Support divisions.

The blueprint also advocates for a space launch system rocket and Orion spacecraft aimed at returning astronauts to the moon, but proposes to terminate the program after just two more missions.

The SLS Megarocket and Orion Spacecraft were fundamental components of NASA’s Artemis Moon initiative, named after the Greek goddess associated with the moon. This mission aimed to create a base camp on the lunar surface and facilitate regular missions.

Critics have pointed out that the SLS rocket exceeds the scale and capabilities of the historic Saturn V booster used in the Apollo missions, resulting in significant delays and budget overruns.

President Donald Trump’s budget draft seeks to terminate the Artemis II test flight, expected to launch in early 2026, as well as the Artemis III mission, planned for mid-2027.

A document outlining the budget requests indicates a shift in NASA’s funding priorities aimed at “returning to the moon and placing the first human on Mars.”

The proposal envisions a hub for space stations in lunar orbit, along with the cancellation of the lunar gateway project, which was intended to play a crucial role in upcoming deep-space missions.

Other significant changes include a $2.265 billion reduction in NASA’s Space Science budget, a $1.161 billion cut in Earth Science funding, and a $5 billion decrease for the International Space Station.

Additionally, these budget cuts will shrink the size of the crew aboard the space station and limit scientific research capabilities, while preparing for its decommissioning by 2030, as part of a transition to commercial space stations, dependent on budget requirements.

In an internal email obtained by NBC News, NASA’s acting administrator, Janet Petro, stated that the proposed budget “demonstrates the administration’s backing for our mission and sets the foundation for our next significant accomplishment.”

She encouraged NASA employees to “exercise patience, resilience, and the discipline needed to achieve unprecedented feats,” acknowledging the budgetary constraints as “difficult choices” that would result in some activities being discontinued.

Among other points, Petro highlighted that under the discretionary budget, NASA would dissolve the SLS rocket and Orion spacecraft programs, as well as the gateway initiative, and halt funding for the Mars sample return project.

Petro’s communications did not specify which aerospace and defense contractors might gain or lose federal support due to these proposed changes. However, companies such as SpaceX, led by Elon Musk, Blue Origin, founded by Jeff Bezos, and the United Launch Alliance (a collaboration between Boeing and Lockheed Martin) are positioned as leading launch providers in the absence of the SLS.

Private Organizations Rise to Fill the Science Gap Left by Trump Administration Cuts

Following the rejection of numerous authors by the Trump administration for the upcoming national climate assessment, two scientific organizations have embarked on initiatives to publish special collections of climate change research.

Earlier this week, researchers were informed that their contributions would no longer be needed for the national climate assessment.

The future of this assessment is uncertain, and some authors have voiced concerns that its integrity is compromised, lacking scientific rigor or the ability to adequately convey the risks associated with climate change.

Robert Kopp, a professor of Earth and Planetary Science at Rutgers University and one of the authors affected by the recent decisions regarding the National Climate Assessment, commented:

In response to the administration’s actions, the American Geophysical Union (AGU) and the American Meteorological Society (AMS) announced on Friday their plans to curate a special collection focused on climate research, as stated in press releases from both organizations.

As per the news release, this collection will span over 20 peer-reviewed journals and aims to “sustain momentum” in the work relevant to the National Climate Assessment, in light of the author and staff rejections.

AGU President Brandon Jones noted in a statement that this special collection is not meant to serve as an “alternative” to the national climate assessment but represents “a unique opportunity to publish new research and reviews that could support climate assessments focused on the U.S.”

The White House has not commented on the rationale behind the rejection of National Climate Assessment authors or the administration’s plans moving forward.

The 1990 Global Change Research Act mandates the U.S. Global Change Research Program (USGCRP) to submit reports to the President and Congress every four years, with national climate assessments previously satisfying this obligation. These reports summarize the best available science on climate change physics, its effects on the U.S., and societal adaptations. They also include localized climate forecasts for various regions to inform the public about community risks.

The latest assessment, published in 2023, comprised around 2,200 pages across 37 chapters. It highlighted that the lower 48 states have experienced an average warming of 2.5 degrees Fahrenheit since 1970, alongside increasingly severe weather events and costly disasters.

“If you’re a state official, business leader, or a member of the public looking to understand the impacts of climate change on the economy, coastal areas, or human health,” Kopp stated:

The National Climate Assessment is a culmination of the efforts of hundreds of researchers volunteering their time, although it is organized by USGCRP staff. In April, the White House ceased funding for this organization.

“I have no insight into the plan; I don’t think anyone does,” Kopp remarked. “They have let go of all the authors and staff of the Global Change Research Program, leaving some government positions currently unfilled.”

The USGCRP website currently states, “We are reviewing the operation and structure of USGCRP.”

Kopp mentioned that the authors of the National Climate Assessment had dedicated about a year to summarizing the chapters intended for their 2027 report and evaluating relevant themes. This summary has already been submitted for review to the federal agency, and the authors are now considering how best to proceed with it.

“We cannot replicate the NCA unless there is an organization prepared to take charge and staff up,” Kopp concluded.

Challenging charging patterns: Why night charging eases grid pressure

ifeelstock/alamy

Offering small financial incentives encourages many electric vehicle owners to charge their cars during off-peak hours, despite the lesser impact of motivational nudges.

This finding emerged from a practical trial illustrating how minor financial rewards can alleviate grid demand during peak times. Such flexibility will become increasingly crucial as the number of electric vehicle users escalates globally.

“Incentivizing nighttime charging led to a 50% reduction in charging periods and a substantial increase in off-peak usage,” says Blake Sheaffer from the University of Calgary, Canada.

Sheaffer and his team engaged 200 electric vehicle owners in Calgary, dividing them randomly into three groups. One group received a financial incentive of 3.5 cents per kilowatt-hour (roughly $10 monthly). The second group was given informational nudges about the societal benefits of off-peak charging, while the third group served as a control, tracking standard charging behaviors without intervention.

Surprisingly, the nudging strategy proved “entirely ineffective,” according to Shaffer. “Simply encouraging them to act out of goodwill didn’t yield significant results.” However, he posits that more frequent reminders than the initial one might have improved outcomes.

In contrast, the financial incentives brought a marked change in charging timings but only while recipients were receiving the money; once the incentives ceased, many reverted to their previous habits.

“The study compellingly demonstrates how small financial rewards can influence electric vehicle charging behavior,” notes Kenneth Gillingham from Yale University. Such rewards might have felt like “easy money” since nighttime charging was largely convenient.

This is particularly significant, as “many energy grids require substantial upgrades,” warns Andrea La Nause from Deakin University in Australia. She points out that her study highlights how financial incentives can lead Australian electric vehicle owners to charge during the day when solar energy inflows peak.

Meanwhile, utility companies like Con Edison and Orange & Rockland in New York have already initiated similar incentive programs to promote off-peak charging.

Severe Heat Waves and Droughts Hit Eurasia Back-to-Back

Drought conditions can have severe repercussions in regions like Karapinar in Türkiye

Over the past two decades, from the grain stores of Ukraine to towns in northern China, Eurasia has experienced a notable increase in droughts following extreme heat events. Tree ring analysis extending back nearly three centuries indicates that human-induced climate change is a significant factor in the acceleration of these combined catastrophes.

This phenomenon presents a severe threat due to the way heat and drought reinforce each other. Elevated temperatures deplete soil moisture, and droughts further reduce the humidity needed to mitigate the impact of subsequent heat waves. This harmful cycle contributes to decreased agricultural productivity and a heightened risk of wildfires.

Certain regions in Eurasia have encountered similar heat and drought patterns in the past, but researchers assert, “current developments exceed natural fluctuations,” according to Hans Linderholm, a researcher at the University of Gothenburg, Sweden.

The complete landscape became apparent only after Linderholm and his team compiled tree ring data covering Eurasia from 1741, which reflects temperature and precipitation variations. This allowed them to recreate a comprehensive distribution of high- and low-pressure systems that influence wet and dry conditions across the continent.

Researchers identified specific phenomena affecting the area, termed the “heatwave motion train of iolarism,” which has intensified since 2000, amplifying anomalies beyond historical measurements. This alteration is associated with atmospheric pressure changes prompted by warming in the North Atlantic and increased precipitation in some regions of North Africa, both linked to anthropogenic climate change.

Rising local temperatures can directly worsen extreme heat and drought situations. However, new research indicates that climate change is modifying the dynamics between distant atmospheric regions (referred to as teleconnections), further complicating the situation, Linderholm explains.

Climate model forecasts predict worsening conditions under all scenarios except for those with the lowest emissions. “We observe a distinct, robust trend in this new teleconnection pattern, suggesting that impacts will escalate in both speed and severity,” states Linderholm.

“It is difficult to envision how [the most affected regions will] recover,” he concludes.

Revolutionary Anti-Venom Solutions Combat the World’s Most Lethal Snakes

Treatment offers protection to mice against venom from common taipans and various other snakes

Matthijs Kuijpers/Alamy

Antibodies derived from inflammatory men exhibit effectiveness against a range of snake bites, suggesting that a universal treatment may soon be achievable.

Annually, snake bites result in the deaths of as many as 137,000 individuals. In addition, there are reported cases of significant complications. Currently, anti-venoms are being manufactured for individual snake species using antibodies sourced from sheep.

The use of non-human antibodies, however, can lead to serious adverse effects, including potentially fatal allergic reactions. Additionally, it necessitates the identification of the specific snake responsible for the bite before administering the anti-venom.

Jacob Granville from Centivax, a biotechnology firm in San Francisco, California, is exploring broadly neutralizing antibodies that could be developed into anti-venoms effective against multiple or all venomous snakes. “There are 650 venomous snake species, but their venoms involve just 10 common classes of toxins,” Granville explains.

Researchers began investigating individuals bitten multiple times by different snakes. “Perhaps a daring snake researcher,” remarks Granville. Media reports introduced the story of Tim Friede, who claims to have “self-administered escalating doses of venom from the world’s deadliest snakes over 700 times.”

“If anyone could yield a wide-ranging neutralizing antibody against snake venom, it would be Tim Friede,” Granville affirms.

From just 40 milliliters of Friede’s blood, the team “converted immune memory into a library of billions of antibodies,” he adds. They subsequently tested promising candidates against venom from 19 of the deadliest Elapidae family species, including several cobra varieties.

Ultimately, they treated two antibodies derived from Friede’s blood, known as LNX-D09 and SNX-B03, along with a toxin inhibitor named varespladib. In experiments on mice, this combination provided comprehensive protection against 13 species, including various cobras, the tiger snake (Notechis scutatus), and the general Thai bread snake (Oxyuranus scutellatus). It also offered partial protection against six additional species, including the notorious death adder (Acanthophis Antalcus).

The subsequent phase involves testing these treatments on animals brought into Australian veterinary clinics following a snake bite and identifying antibodies that can confer protection against vipers.

Tian Du from the University of Sydney emphasizes that “discovering two antibodies that can inhibit toxins makes for a universal treatment for closely related species.”

Additionally, after learning that the anticoagulant drug heparin can assist individuals in avoiding limb loss following a cobra bite, Du aims to determine whether their treatment can also avert skin and muscle necrosis.

Viewing Halley’s Comet Fragments During the Eta Aquariid Meteor Shower

Halley’s Comet makes its appearance near Earth every 75 years. Nevertheless, the remnants of this comet give rise to two significant meteor showers annually: the Eta Aquarids.

During this meteor shower, the night sky lights up as Earth travels through the paths left by various famous comets, according to Shauna Edson of the Smithsonian National Air and Space Museum.

NASA’s Bill Cook describes the Eta Aquarids as “very fast meteors.”

On the peak night, which falls on Tuesday morning, we anticipate witnessing 10-15 meteors per hour under optimal viewing conditions, Cook noted.

However, with the moon approximately two-thirds full, visibility may be diminished.

The viewing period will extend until May 28th. For more information about the Eta Aquarids and other meteor showers, check out this meteor shower guide.

What is a Meteor Shower?

As Earth orbits the Sun, it encounters bits left behind by comets and sometimes asteroids several times a year. The Eta Aquarids originate from fragments of Halley’s Comet.

When these fast-moving space rocks enter Earth’s atmosphere, they experience friction with the air, causing them to heat up and eventually incinerate.

This process can create a brief glow in the surrounding air, leaving a luminous tail that marks the path of a “shooting star.”

You don’t need any special gear to view the meteor showers that light up the sky each year, just find a dark spot away from city lights.

How to View the Meteor Shower

The optimal time for observing meteor showers is early when the moon is positioned low in the sky.

The primary challenges to clear visibility are bright moonlight and artificial lights. A cloudless night with a faint moon provides the best conditions.

Remember to keep looking up. If you haven’t been distracted by your phone, your eyes will be well-adapted to spot a shooting star.

When Will the Next Meteor Shower Be?

The next major meteor shower, the South Delta Aquarids, will peak in late July.

Research: Multiple Groups of Pterosaurs Became Global 160 Million Years Ago

Pterosaurs often glide above dinosaurs, but recent examinations of fossilized footprints reveal that some of these flying reptiles were equally adept at terrestrial movement.

Image credit: Smith et al, doi: 10.1016/j.cub.2025.04.017.

“We have been diligently working to enhance our understanding of these creatures,” stated Robert Smith, a doctoral researcher at the University of Leicester.

“These findings provide insights into their habitats, movement patterns, and daily activities in ecosystems long since vanished.”

In this research, Smith and his team identified three distinct types of pterosaur footprints, each offering insights into various lifestyles and behaviors.

By correlating footprints with specific groups, a robust new method emerges to study how these flying reptiles thrived, migrated, and adapted to diverse ecosystems over time.

“Finally, 88 years after the initial discovery of Pterosaur tracks, we have pinpointed precisely who created them and how,” remarked Dr. David Unwin, Ph.D., from Leicester.

Perhaps the most striking revelation comes from a group of pterosaurs known as Neoazdalci. Quetzalcoatlus, one of the largest flying creatures, boasts a wingspan of 10 meters.

Their footprints have been found in both coastal and inland areas worldwide, supporting the theory that these long-legged animals not only soared through the skies, but also inhabited the same environments as numerous dinosaur species.

Some of these tracks date back to an asteroid impact event 66 million years ago, coinciding with the extinction of both pterosaurs and dinosaurs.

Ctenochasmatoids, recognized for their elongated jaws and needle-like teeth, left footprints primarily found in coastal sediments.

These animals likely walked along muddy shores or shallow lagoons, employing unique feeding strategies to capture small fish and floating prey.

The prevalence of these tracks suggests that these coastal pterosaurs were far more common in these habitats than than the rare fossilized remains.

Another type of footprint was located in rock formations, where fossilized remains of the same pterosaur were also found.

The close association between footprints and skeletons offers compelling evidence for identifying the track makers.

These pterosaurs, known as Dsungaripterids, possessed robust limbs and jaws; their toothless, curved beaks were adept at securing prey, while their large, rounded teeth were ideal for crushing shellfish and other resilient foods.

“Footprints are often overlooked in Pterosaur studies, yet they yield a wealth of information about the behaviors and interactions of these creatures with their environment,” emphasized Smyth.

“A detailed analysis of these footprints allows us to uncover biological and ecological insights that other methods may not provide.”

The team’s paper was published in the journal Current Biology.

What Does Australia’s Vote Indicate for Climate Action in a Major Coal Economy?

Few voters have as much influence over climate change as Australians do.

In terms of per capita greenhouse gas emissions, only the US and Canada are close to Australia. The nation stands as one of the largest exporters of fossil fuels, significantly contributing to global warming by selling vast quantities of natural gas to Asian countries, alongside some of the most polluting fossil fuels.

As national elections approach this Saturday, polls indicate that climate change is not a primary concern for many voters. However, the leading candidates from the Labour Party and the Liberal Party hold starkly different views on climate and energy policies.

At the forefront is the reliance on aging coal plants, which dominate the country’s electricity generation.

“We’ve seen various approaches worldwide,” stated Andrew McIntosh, a professor of environmental law and policy at the Australian National University. “On one hand, there’s a push for expanding renewable energy, while on the other, a conservative coalition advocates for nuclear power.”

Both strategies aim to reduce emissions, according to McIntosh, though many remain puzzled by the nuclear initiative. Nuclear plants can take over a decade to build, while renewable energy solutions can be implemented in just a few months.

“We need to rely on coal for years to come,” he added.

In some ways, analysts compare the polarized situation in Australia to that in the US, where former President Donald J. Trump downplayed climate science, dismissing it as a scam. Matt McDonald, a political scientist specializing in climate matters at the University of Queensland, remarked:

However, instead of heightening Australians’ concerns about climate change, Trump’s criticisms “don’t seem to have generated significant international momentum to address the issue, effectively cooling tensions on both sides,” said Dr. McDonald.

If Australians are feeling pressure, it stems from surging household energy prices. According to Australian energy regulators, average energy costs have risen by approximately 60% over the last decade.

Anthony Albanese, the current Prime Minister and Labour Party leader, has committed to a relatively ambitious renewable energy target, aiming for over 80% generation by 2030.

“Yet,” Dr. MacDonald noted, “we still have a significant reliance on coal.”

Albanese’s main rival, Peter Dutton, heads a coalition that aims to increase domestic gas production for electricity generation. While gas is still a fossil fuel, it is far less polluting than coal. Dutton proposes requiring gas producers to sell portions of their output to Australian electricity grids while expediting approvals for new drilling projects.

Generally, both parties endorse gas development, with Australia being the second-largest gas exporter globally, following the US.

Polling indicates a competitive race, revealing that the Green Party and the so-called Teal Independents strongly advocate for robust climate policies and could play a crucial role in Congress. “If they maintain their current seats, they will be in a position to advocate more strongly for climate action, such as reducing coal exports,” Dr. McDonald said.

A significant question looming globally is whether Australia will host next year’s annual United Nations-sponsored Global Climate Conference, commonly known as COP. Australia is currently vying with Türkiye to secure this event, which comes with notable geopolitical significance and economic advantages, drawing tens of thousands of delegates.

Host countries typically influence the ambition levels of negotiations, and Prime Minister Albanese’s administration has been lobbying for international support for Australia’s bid for over a year. “If they are elected, it’s unlikely to happen under the coalition government,” Dr. McDonald concluded.

Ronan of Sea Lion Likely Outshines You at Keeping the Beat

Meet Ronan, a California sea lion who probably has better rhythm than you do.

Researchers have demonstrated that Ronan, a resident at the Long Marine Lab at the University of California, Santa Cruz, was the first non-human mammal trained to keep the beat through movement to music. This took place back when Ronan was young, in 2013. Recently, scientists decided to reassess the skills of this now 15-year-old sea lion, revealing not only an enhancement in her ability to bob her head in sync with the music but also that she outperformed most humans in doing so.

“This ultimately shows that humans aren’t the only mammals that can sustain a beat,” said Tecumse Fitch, a cognitive biologist studying biomimetics at the University of Vienna, who was not involved in the new research. The findings were published on Thursday in Scientific Reports.

Parrots are known to keep the beat through their movements, and recent studies have highlighted similar rhythmic abilities in monkeys and other mammals such as rats. However, over a decade later, “the rhythmic abilities of sea lions are distinctly recognized among non-human vertebrates,” Dr. Fitch stated.

Researchers worked with Ronan for several months, focusing on enhancing her accuracy with the original tempos she had learned. They then compared her ability to maintain the beat now to when she was three years old.

The team evaluated Ronan’s ability to move her head to a tempo of 112, 120, and 128 beats per minute, contrasting her head movements with those of 10 individuals aged 18-23 moving their arms. “The hands function similarly to a sea lion’s head, and their arms resemble the necks of a sea lion in size, making it a valid comparison for measuring movement capabilities.”

Across all assessment parameters analyzed by Dr. Cook and his team, Ronan topped the class.

“Ronan outperformed everyone on every measure of accuracy and consistency,” stated Dr. Cook. “In all respects, she excelled beyond most people, truly setting herself apart.”

Ronan’s headbanging abilities sparked debate in 2013 regarding whether her skills could truly be compared to those of humans, as well as whether such behavior is common in the animal kingdom or restricted to species capable of learning complex vocalizations, like humans and parrots, which allow spontaneous rhythmic movement.

“What Ronan does appears indistinguishable from what humans are adept at,” Dr. Cook remarked. He believes that the new findings about Ronan’s capabilities further challenge the assumption that rhythmic timing is inherent only to vocal learners.

Some scientists challenge this conclusion.

Aniruddh D. Patel, a cognitive neuroscientist at Tufts University, maintains that the ability to naturally synchronize with music is exclusive to certain species that can inherently learn complex vocal patterns.

He suggests further research into the vocal learning abilities of sea lions would corroborate this hypothesis. Nonetheless, he emphasizes that the “crucial distinction” lies in the fact that Ronan has been trained to keep the beat.

Moving forward, Dr. Cook and his colleagues aim to investigate whether Ronan can maintain rhythm with less predictable beats.

“Can she adjust her tempo by speeding up or slowing down? Can she handle variations that aren’t steady?” Dr. Cook questioned. “These are things that humans excel at. Can non-humans do them?”

Washington’s Turmoil Hinders Efforts to Combat Avian Flu

Interviews with over a dozen scientists and federal officials reveal that the initiative to control bird flu on farms has been hindered by a tumultuous administration transition, which prioritized cost-cutting, reduced federal employment, and limited communication.

On one poultry farm alone, more than 168 million birds were culled to mitigate the outbreak. The virus, first identified in American dairy cows about a year ago, has spread to 17 states and is increasingly prevalent. A flock of 1,000 birds was affected.

In the early months, the Trump administration dismissed a team of scientists crucial for tracking the virus’s spread, canceling significant meetings and limiting data access for federal scientists.

The Department of Health and Human Services has not held a public briefing on bird flu since January and has not responded to inquiries for comments.

Health Secretary Robert F. Kennedy Jr. suggested letting the virus spread unchecked among poultry to distinguish vaccinated birds, an idea supported by Democratic lawmakers. This opened the survey into the federal response.

The Trump administration also removed funding for the Food and Agriculture Organization’s program, a UN body responsible for monitoring and controlling avian flu in 49 countries.

“We’ve noted considerable challenges,” highlighted Lindsay Mar, a specialist in airborne viruses at Virginia Tech.

“Animals and people provide strong warning signs. Yet we merely observe them and fail to act,” she remarked.

Avian influenza has impacted various mammal species, including 150 cats, with at least 70 cases across 26 states resulting in four hospitalizations and one death. Following the winter lull, the spring travel season has reignited the infection rates.

In the past 30 days, the Ministry of Agriculture has reported 47 new infectious cases across three states.

Currently, the H5N1 virus does not seem capable of human-to-human transmission. Nonetheless, a recent mutation appears to be edging closer to that possibility.

This week, an international group of virologists concluded that continuous monitoring of milk from dairy farms, wastewater, and individuals working with infected animals is vital.

Authorities are testing bulk milk to help identify infected herds. However, the agricultural sector’s strategy to counter bird flu is currently focused on lowering egg prices, with little mention of dairy cows.

Agriculture Secretary Brooke Rollins has proposed enhancements to farm biosecurity to assist farmers in ten states in curbing the virus’s spread on their premises.

“The initial emphasis of these ongoing efforts will be on egg-soaking facilities as part of USDA’s coordinated strategy to tackle egg prices, but we anticipate the inclusion of other poultry and dairy producers as the program expands,”

An early wave of federal layoffs impacted a veterinarian in the avian flu-focused agriculture sector, leading to both terminations and rehiring. Today, many continue to manage government-issued credit cards with restrictions that complicate travel and procurement of necessary supplies without seeking extended credit.

The Agriculture Department defended its policies, stating, “The restrictions on government-issued credit cards will automatically relax once personnel obtain travel approval,” according to a department spokesperson via email.

On April 1, the Trump administration dismissed veterinarians and scientists at the Food and Drug Administration investigating raw pet food contaminated with H5N1, which had adversely affected cats, and was pivotal in assisting veterinarians in developing proposals for vaccines and treatment of infected animals.

According to an anonymous official fearing retaliation, the CDC has begun withholding genetic analyses of virus samples collected from patients. Even some internal teams can no longer access this information.

Typically, federal agencies release data 242 days post-collection, as revealed by a recent analysis. Ideally, this process should only take a few weeks, according to scientists. Such delays complicate the tracking of the virus’s spread and accurate assessment of risks to the public.

Significant reports in the agency’s publications, such as weekly morbidity and mortality records, have been affected, mentioned the former anonymous official.

In February, instead of the scheduled reports on avian flu infections in domestic cats, agency scientists were instructed to prioritize a paper on the impact of LA wildfires on air quality.

While research on avian flu emerged weeks later, agency staff expressed their discontent with the delayed directives from superiors.

The Biden administration has been holding regular inter-departmental calls on avian flu, involving numerous external experts and state health officials, to share the latest findings. These discussions have been diminished, much like the CDC’s guidance on monitoring.

All communication from the CDC requires clearance from federal health officials in Washington. The agency has not held an avian flu press conference since January.

“There have been numerous health challenges,” remarked Dr. Adam Rowling, a virologist and infectious disease specialist at the University of Michigan.

The nation retains stockpiles containing millions of doses of human vaccines against avian influenza. However, amid budget cuts, agencies responsible for these stockpiles and rapid emergency distribution have shifted under the CDC.

Dawn O’Connell, who leads the administration for strategic preparation and response, an agency that has maintained its stockpile under the Biden administration, noted that this shift would “add a layer of bureaucracy instead of removing it.”

In interviews, several employees from the CDC and agricultural sector expressed low morale, worsened by successive layoffs. During a City Hall gathering on April 16, around a quarter of the veterinarians present indicated they would consider signing onto a deferred resignation program that offers full pay and benefits until September 30th.

Over the past year, it has been challenging to monitor cows infected with H5N1. They exhibited fever and produced thick yellow milk, with some cows suffering voluntary abortions.

However, reinfections have been found in cows, with second-round symptoms being subtle, complicating the identification of infected cows and protecting those who interact with them. Currently, rapid testing for the virus in cattle and humans is unavailable.

Reinfection indicates that the virus may permanently colonize dairy cows. Meanwhile, the virus continues to circulate among wild birds, evolving approximately twice as fast in birds as in cows.

A new variant, known as D1.1, which is believed to cause more severe illness, emerged in September and quickly became the dominant strain. The government’s response has not matched this rapid evolution.

In Nevada, milk samples collected on January 6th and 7th tested positive for avian influenza by January 10th. Ideally, the 12 farms contributing these samples would have been quarantined while confirming results.

Instead, further samples were gathered on January 17th, with results confirmed a week later.

The Agriculture Department stated that delays in test results would not impede the outbreak response. “It is crucial to note that response activities operate independently of the sequence of the results and occur as needed,” the department claimed.

Michael Warby, an evolutionary biologist at the University of Arizona, expressed skepticism, noting, “This appears to be a situation where the barn door is closed after the cows have escaped.”

He suggested that it’s still feasible to eradicate the virus on American farms if the Agriculture Bureau enhances containment measures.

For instance, a rapid testing method that detects H5N1 in bulk milk could provide officials with more time to eliminate outbreaks, compared to tests that yield results after several weeks.

“We believe this is a goal to pursue unless it proves futile,” Dr. Warby commented regarding the virus’s expulsion.

At present, removing the virus from farms is not straightforward.

For example, if an infected duck flies over a farm and defecates, an outbreak could commence among millions of birds. Farmers may inadvertently transport remains into chicken coops, and infected rodents can enter through small openings.

Chickens are densely packed and have weak immune systems; a single sneeze can quickly infect hundreds or even thousands.

Over the past two years, the Agriculture Department has collaborated with egg producers in four states: Iowa, Minnesota, South Dakota, and North Dakota.

Federal officials have assisted in identifying and removing surrounding wildlife, including mice, and have eliminated potential virus entry points that farmers might overlook. Notably, only two out of 108 facilities involved in the pilot program reported subsequent virus outbreaks.

This project is slated to expand this year to ten states, including California, Texas, Ohio, and Pennsylvania, with plans to reach all 50 states by 2027. Agricultural experts aim to help farmers identify even the smallest vulnerabilities against avian flu.

While this proposal has garnered praise from scientists, some experts, including veterinarians in agriculture, are uncertain about its implementation.

Department staff have been striving to combat bird flu since early 2022. There is already an insufficient workforce to detect facility weaknesses necessary for farm operation and readiness for reopening.

“We’ve been working continuously for three years, leading to increasing fatigue among staff,” noted a veterinarian who requested anonymity without permission to engage with the media.

Given the current situation on farms, even stringent measures may not suffice to bar the virus, remarked Andrew Decoriolis, executive director of Advocacy Group Farm Fight.

“The outbreak is likely to persist until the industry undergoes significant transformation,” he remarked.

US Prosecutors Charge Major Insurance Firms with Paying Kickbacks for Private Medicare Plans

The Justice Department has charged three major health insurance companies with engaging in illegal kickback schemes totaling hundreds of millions of dollars over several years, involving payments to insurance brokers who guided individuals to private Medicare plans.

Federal prosecutors also alleged that two of these insurers colluded with brokers to discriminate against individuals with disabilities by hindering their enrollment in private Medicare plans, based on the belief that these plans would be costlier.

Around 12% of Medicare beneficiaries, who are disabled and under the age of 65, qualify for the federal insurance program. Their intricate health requirements often lead to high care costs.

According to a complaint initially filed by whistleblowers, the Department of Justice has joined the case against the nation’s largest health insurance company, previously known as Anthem. Humana is also implicated for allegedly funneling kickbacks to three large brokers—Ehealth, GoHealth, and SelectQuote—to boost enrollment in Medicare Advantage plans, which have also been tied to fraudulent activities.

A complaint filed in federal court in Boston claims that the kickback scheme spanned from at least 2016 to 2021, accusing Aetna and Humana of discrimination against individuals with disabilities.

Aetna, Elevance, GoHealth, and Humana have denied the allegations, although others have not responded to requests for comments.

This lawsuit is one of the first indications of the Trump administration’s scrutiny of certain Medicare Advantage plans, which face ongoing federal oversight. Critics, including lawmakers, have condemned these popular plans for potential overcharging the federal government through aggressive marketing strategies. Over half of all individuals enrolled in the federal program are covered by Medicare Advantage plans.

During the Senate confirmation hearing for Dr. Mehmet Oz, he assured concerned senators about the oversight of Medicare plans, promising a “new sheriff” to address excesses.

Brokers play a crucial role in assisting senior Americans in selecting private Medicare plans. However, the allegations suggest brokers have directed individuals to plans that offer the highest commissions instead of the best fit for their needs.

In recent years, small local brokerage firms have been overshadowed by large national organizations that employ numerous agents and utilize call centers and websites like those mentioned in the lawsuit. These companies increasingly depend on technology to help brokers identify the optimal plans for callers, facilitating the kind of steering described in the allegations.

The Biden administration implemented regulations last year aimed at reducing the commissions insurance companies can pay to brokers for patient enrollments. Recent Congressional testimonies and consumer complaints have indicated that insurers are offering bonuses to brokers for enrolling more individuals in specific plans, regardless of their actual needs. However, the lawsuit is still pending.

Regarding cases involving disabled individuals, federal prosecutors have stated: “The efforts to specifically exclude beneficiaries are even more ruthless given that their disabilities may render them less profitable for health insurance companies,” said attorney Leah B. Foy. “We will continue to investigate and prosecute the greed targeting these beneficiaries.”

Federal Report Criticizes Adolescent Gender Treatment

On Thursday, federal health authorities released a report stating there is no scientific basis for administering hormones or surgical interventions to young individuals experiencing gender dysphoria. This marks a significant shift from prior agency guidelines and the recommendations made by various US health organizations, highlighting concerns surrounding potential long-term harm.

The report emphasizes the importance of psychotherapy, which has sparked considerable debate, as some proponents equate it with conversion therapy aimed at altering gender identity.

Certain sections of the review appeared to challenge the very notion of a gender identity that diverges from one’s sex assigned at birth.

In January, President Trump issued an executive order titled “Protecting Children from Chemical and Surgical Amputations,” directing the Department of Health and Human Services to compile a report within 90 days on optimal treatment approaches for youth indicating a disconnect between their gender identity and their birth sex.

The executive order suggested that the administration had already drawn its conclusions about gender transition treatments for minors, denouncing the “blatant harm done to children” as a “stain on our country’s history.”

The report, spanning 400 pages, adopted a calmer tone yet arrived at a similar verdict. Notably, the report’s author remains unidentified as the post-publication review process is set to commence in “the coming days.”

Officials at HHS declined to comment on the review process, noting contributors included a diverse group of physicians, medical ethicists, and methodologists selected for their commitment to scientific integrity.

Importantly, the report clarified that it is not designed to establish standards for healthcare or formulate policy recommendations.

The findings were primarily based on analyses of scientific studies regarding adolescent blockers, hormone treatments, and surgical interventions conducted over the past few decades as these therapies became accessible to adolescents.

The assessment concluded that while the advantages of medical interventions remain unclear, potential harms, including erosion of birth rates, are deemed less substantial.

“Clinical practice in this area is exceptional and concerning,” the report asserts, pointing to American medical groups that advocate for an intolerant atmosphere where clinicians may feel compelled to self-censor.

The appropriateness of treatments such as adolescent blockers, hormone therapy, or surgery for young individuals remains a subject of vigorous debate.

Recently, several European nations have imposed restrictions on such treatments, with scientific reviews and discussions highlighting the insufficient quality of supporting evidence and uncertainties about long-term risks.

In the United States, 24 states have enacted legislation preventing doctors from offering such treatments to adolescents.

The American Academy of Pediatrics is conducting its own evidence review. The Academy and most significant medical organizations in the US continue to support these treatments as effective in relieving the psychological distress many transgender youth experience.

“This report misrepresents the prevailing healthcare consensus and fails to represent the realities of pediatric care,” stated Dr. Susan Cresley, chair of the Academy. “This document favors opinions over a rational examination of evidence.”

Advocates for transgender rights criticized the report for presenting ideological views disguised as scientific.

During Trump’s initial 100 days in office, his administration aimed to downplay transgender identities in public forums. The measures included cutting funding for hospitals that provide gender transition treatments to individuals under 19 and contemplating barring transgender individuals from military service.

The administration facilitated the transfer of transgender men and women from federal prisons to their homes and ceased recognizing the gender of transgender individuals on their passports.

“Is the administration’s animosity towards this healthcare grounded in genuine scientific insights or ideologically motivated by its disapproval of transgender individuals believing that transgender identity is fabricated?” questioned Shannon Minter, director of legal affairs at the National Center for Lesbian Rights.

The Center represents transgender plaintiffs in multiple lawsuits contesting the administration’s policies’ constitutionality.

“This is an ideological declaration, not a medical one,” stated Casey Pick, director of law and policy at the Trevor Project, an organization focused on suicide prevention among LGBTQ youth.

This report signifies a triumph for individuals who categorize this medical field within a broader agenda to deny the reality of biological gender.

Roger Severino, vice president of domestic policy at the Heritage Foundation, commended the HHS report while condemning “profit-driven physicians and ideological groups” for convincing families that “children’s sex aligns with everything they profess.”

According to government statistics, around 3% of high school students identify as transgender, a significant surge over the last decade. However, a much smaller percentage of these adolescents seek medical interventions.

Despite this, the topic of medical transition for minors has turned into a political battleground, with Trump making it a focal point of his campaign while some Democrats believe this strategy may aid his electoral prospects.

The new HHS report extends beyond similar assessments in Europe, which have initiated new limitations on gender-related treatments for adolescents.

Independent Clinical Services Reviews for UK youth reached a comparable conclusion, led by Dr. Hillary Cass, former president of the Royal College of Pediatrics. It noted the insufficient quality of evidence supporting the use of adolescent blockers and hormone treatments for minors, with surgery being unavailable to minors in the UK.

However, this review, conducted over four years, painted a broader picture of the medical landscape by consulting young patients, transgender adults, parents, and clinicians.

Dr. Kass concluded that evidence regarding the benefits and risks associated with treatment is “significantly weak,” but acknowledged that some young individuals are very likely to benefit from early interventions.

“Certain young people will undoubtedly reap the benefits of the medical pathway. As research evolves, we need to ensure that those individuals can access care under research protocols, but we mustn’t assume this is the right path for everyone,” Dr. Cass expressed in an interview last year.

This review concluded that the use of blockers in England should be restricted and that clinicians are encouraged to prescribe hormones to teenagers only with “extreme caution.”

Other clinicians who have expressed concern about the field of adolescent gender medicine are unclear about how the new report will be applied.

“We are pleased that in recent years US authorities are finally considering what is happening in Europe,” remarked Erica Anderson, a child psychologist and former president of the American Transgender Health Association.

She is outspoken about her concerns that adolescent gender clinics are shifting away from thorough mental health evaluations in light of the growing number of children seeking gender treatment.

However, Dr. Anderson supports the need for early intervention for certain young people, despite the inflammatory presidential order leading to the report.

“It’s akin to calling someone out on their rank and then expecting to engage in a meaningful conversation,” she stated. “This approach doesn’t work well with real individuals, who possess emotions and histories.”

Minter from the National Center for Lesbian Rights argued that by emphasizing psychotherapy over medical interventions, the HHS report effectively endorses conversion therapy aimed at altering minors’ gender identity or sexual orientation.

Various medical associations support prohibiting the practice, citing evidence that it leads to depression, anxiety, and feelings of self-loathing.

However, the Supreme Court has agreed to review a First Amendment challenge concerning Colorado’s conversion therapy regulations, initiated by a licensed professional counselor who contends that “individuals prosper when they align with God’s design, including their biological sex.”

Other therapists, including Dr. Anderson, advocate for what they term “exploratory therapy” which assists supportive clinicians in addressing mental health challenges related to adolescents’ gender identity.

Kellan Baker, a researcher focusing on transgender health policies at Whitman-Walker, a Washington-based nonprofit health center, remarked that the report signifies a divergence from customary health policy development in the US.

“It’s crucial that healthcare is administered by individuals with specialized knowledge, not dictated by the federal government, but by skilled clinicians operating according to the standards set by their respective healthcare fields,” Dr. Baker stated.

He voiced concerns that the report could be utilized by the government as a pretext for denying medical coverage for transgender youth.

The Centers for Medicare and Medicaid Services, a branch of HHS, issued a letter last month directing Medicaid agencies to refrain from using funds for gender transition care for minors.

Attorney General Pam Bondy instructed the Department of Justice to investigate doctors who provide such care, stating, “This document does not represent standard care and will likely be cited by the government as grounds for denying medical care coverage for transgender youth.”

What Does the Australian Election Outcome Mean for Climate Policy in a Major Coal Economy?

Few voters can impact climate change as significantly as Australians.

In terms of per capita greenhouse gas emissions, only the US and Canada closely approach Australia. The nation stands as one of the largest exporters of fossil fuels contributing to global warming, notably sending vast quantities of natural gas to Asian countries alongside some of the most polluting fossil fuels.

As the country prepares for national elections on Saturday, polls indicate that climate change is not a primary concern for many voters. However, the leading candidates from the Labour Party and the Free State Union present starkly different approaches to climate and energy policy.

Central to the discussion is the dependence on the aging coal plants that generate electricity for the country.

“We’ve witnessed a lot of global experiences,” noted Andrew McIntosh, professor of environmental law and policy at Australian National University. “One perspective emphasizes workforce requirements and the need for increasing renewables, while the alternative espouses a conservative coalition favoring nuclear energy.”

Both strategies could lead to reduced emissions, according to McIntosh, though many are puzzled by the nuclear program. Constructing nuclear power plants can take over a decade, whereas renewable energy sources can be implemented within months.

“We need to rely on coal for the foreseeable future,” he added.

In some ways, analysts reflect a polarized debate akin to that in the US, where former President Donald J. Trump dismissed climate science and branded efforts to clean energy as a hoax. Matt McDonald, a political scientist specializing in climate issues at the University of Queensland, stated:

“However, rather than making Australians more apprehensive about climate change, Trump’s rhetoric has not gained significant traction internationally, effectively cooling the debates on both sides,” remarked Dr. McDonald.

For Australians feeling the pressure, it largely stems from rising energy costs for households. Australian energy regulators report that average energy prices have surged by approximately 60% over the past decade.

Incumbent Prime Minister Anthony Albanese, who leads the Labour Party, has proposed an ambitious target for renewable energy, aiming for over 80% generation by 2030.

“But,” Dr. McDonald pointed out, “we have substantial coal reserves as well.”

Albanese’s main rival, Peter Dutton, at the helm of a liberal coalition, advocates for increased domestic gas production to support electricity generation. While gas is a fossil fuel, it is considerably less polluting than coal. Dutton proposes that gas producers be mandated to supply a portion of their output to Australian power grids, while also expediting the approval process for new drilling projects.

Generally, both parties are proponents of gas development, with Australia being the world’s second-largest gas exporter after the US.

With polls indicating a tight race, the Green Party and the so-called Teal Independents, both strong advocates for robust climate policies, could potentially influence Congress significantly. “If they retain their seats, they’ll be poised to push harder on climate initiatives—like decreasing coal exports,” Dr. McDonald noted.

An additional point of contention globally is whether Australia will be the host for the upcoming United Nations-sponsored Global Climate Conference next year, commonly referred to as COP. Currently, Australia is vying with Türkiye for the hosting rights, an opportunity carrying geopolitical significance and economic advantages by welcoming tens of thousands of representatives.

Hosting nations often establish the dialogue tone for consultation ambitions, and Prime Minister Albanese’s government has been actively lobbying other countries for over a year to support Australia’s bid. “If the coalition wins, this opportunity will certainly vanish,” Dr. McDonald asserted.

NASA Astronauts Venture Outside the Space Station for Fifth All-Female Spacewalk

The astronaut missed during the first all-female spaceship due to a sizing issue with the space suits. Six years later, I finally got my chance on Thursday.

NASA’s Anne McClain ventured out from the International Space Station alongside Nichole Ayers. Both are military officers and pilots who returned instead of going to the Orbit Lab in March with two other astronauts. Now, I’m back home.

Just before floating out, McClain spotted a loose string on the index finger of her right glove. Mission Control briefly postponed the launch to ensure her glove was secure.

During the mission, the duo prepared the space station for a new solar panel and adjusted the antenna at the 260-mile-high complex.

On Wednesday evening, the space station needed to be elevated slightly to avoid debris: remnants of a 20-year-old Chinese rocket.

McClain, an army colonel and helicopter pilot, was originally set to participate in the first all-female spacewalk in 2019, but the medium-sized suit was insufficient. The historic mission was accomplished by Christina Koch and Jessica Meir. This latest outing marks the fifth time a woman has gone outside the spacecraft in a 60-year history.

Koch is set to become the first woman to fly to the moon. Along with three male astronauts, she will orbit the moon without landing next year as part of NASA’s Artemis program, the successor to Apollo.

Currently, men continue to outnumber women in NASA’s astronaut corps.

Out of NASA’s 47 active astronauts, 20 are women. Among the seven astronauts now aboard the space station, McClain and Ayers are the only females. This marks Ayers’ first mission, while McClain is on her third.

Ronan the Sea Lion: Keeping Time Better Than Humans

Ronan, the sea lion, continues to keep the rhythm even after all these years.

She can create grooves with rocks and electronic music. However, her talent truly shines as she bobs along to classic hits like “Boogie Wonderland.”

“She’s absolutely nailing it,” said Peter Cook, a behavioral neuroscientist at the University of Florida, who has dedicated a decade to studying Ronan’s rhythmic talents, observing her shake her head in sync with tempo changes.

While many animals lack the ability to recognize the beat, humans, parrots, and some primates can. Ronan, however, is prompting scientists to reconsider what music means.

Rescued years ago, she rocketed to fame about a decade ago when researchers highlighted her musical abilities. Since she was three, she has called the Ocean Institute at the University of California, Santa Cruz her home, where she has assisted researchers, including Cook, in recognizing rhythms.

Ronan is part of a group of remarkable animals, including cockatoos, challenging the long-held belief that only humans excel in responding to music and identifying beats.

Notably, Ronan learned to dance to the beat without needing to learn how to sing or produce music.

“Previously, it was thought that only vocal learners, like humans and parrots, could discern beats,” noted Hugo Merchant, a researcher at the Institute of Neurobiology in Mexico.

However, after Ronan became a star, questions emerged regarding her sustained abilities. Was her previous acclaim a fluke? Could she even outperform humans in maintaining the beat?

A chef and fellow researchers devised a plan to tackle this question. Their findings, detailed in new research published in the journal Scientific Reports, confirm that Ronan remains a star.

This time, researchers focused on lab tempos using percussion instruments, rather than recorded music. During the study, Ronan shook her head to three distinct tempos: 112, 120, and 128 beats per minute. These tempos were unfamiliar to her, enabling scientists to test her adaptability to new rhythms.

Ten university students participated in a similar task, showcasing their abilities as well.

Ronan emerged as the top performer.

“No one outperformed Ronan across the various tests for beat keeping,” Cook shared, adding, “she’s significantly improved since childhood.”

Hencan Horning, a music cognition researcher at the University of Amsterdam and not involved in the study, stated that the findings reinforce Ronan’s status as one of the leading examples of animal musicality.

Researchers plan to train and evaluate other sea lions. Cook believes others might also have beat-keeping abilities, but Ronan remains a standout star performer.

Introducing the New England Team Dedicated to Seal Conservation

Block Island, Rhode Island – The enigmatic aquarium animal rescue team is busier than ever.

With binoculars in hand, Program Manager Sarah Curran surveys the coastline, facing an increasing problem on Block Island.

When fishing gear, litter, or balloons entangle a gray seal’s neck, these marine mammals, which can weigh over 800 pounds, may suffer serious injuries or even death as the restraints tighten.

Thus far this year, Connecticut nonprofits have reported 20 tangled gray seals, surpassing the usual count recorded by Mystic each year.

Curran affectionately dubbed one of the seals “anxiety.”

Intertwined stickers.
Mysterious aquarium

NBC News has been granted rare access to follow Mystic’s collaboration with the Atlantic Marine Conservation Association and the Brock Island Maritime Institute, which recently formed.

Curran and her team navigated around a group of seal pups basking at the water’s edge. They skillfully separated the entangled pups and dashed on bright red boards to capture them with precision and speed.

Once a pup was secured, the team worked quickly to attach a tracker for research and freed it from the fishing net constricting its neck.

“We can release stickers today and avoid the need to transport them to the clinic for rehabilitation,” said Curran, who leads the effort. “The sooner you can intervene, the better the chances of recovery.”

This team previously photographed a seal pup stuck with a plastic object in downtown New Haven, Connecticut, in February. The pup, with its big eyes and gentle whine, captured the public’s heart and even received the name “Chappy” through a voting contest.

Unfortunately, Chappy’s story didn’t have a happy ending. In a statement online, Mystic reported that pieces of plastic were found in his stomach, highlighting the dangers that marine debris, particularly plastic, poses to marine life.

Some estimates indicate that plastic pollution claims the lives of over 100,000 marine mammals annually.

“The number of animals interacting with human debris in their early months of life is quite alarming,” Curran stated.

In this ongoing battle, Mystic remains undeterred.

The team celebrated as the seals returned to the sea, now freed from the constraining nets.

“It’s a special moment to give these animals a second chance at life,” Curran remarked. “It’s truly rewarding to witness.”

Soviet-era Spacecraft Poised to Re-enter Earth After Half a Century of Failed Venus Mission

A Soviet-era spaceship aims to land on Venus, with plans for it to return to Earth in the near future.

Currently, it is uncertain where the mass of half-ton metal will descend and how much will survive the journey. Experts are monitoring space debris.

Dutch scientist Marco Langbroek estimates that the spacecraft may re-enter Earth’s atmosphere around May 10th.

“There are risks involved, but there’s no need for excessive concern,” Langbroek stated in an email.

The object is relatively small, and even if it remains intact, the likelihood of it causing damage is similar to that of encountering a random meteorite fall, which occurs annually. “The chance of being struck by lightning in your lifetime is far greater,” he added.

He also mentioned that the spacecraft could potentially impact someone or something; however, this scenario cannot be entirely dismissed.

The Soviet Union sent the spacecraft, known as Cosmos 482, into orbit in 1972 as part of its Venus mission series. It never successfully launched from Earth orbit due to a rocket malfunction.

Most of its counterparts fell back within a decade, yet Langbroek and others believe the landing capsule, a spherical object about three feet (1 meter) in diameter, has been in a highly elliptical orbit for the past 53 years, gradually descending.

There is a substantial possibility that the over 1,000-pound (approximately 500 kilograms) spacecraft could endure re-entry. It was designed to withstand the harsh conditions of Venus’ atmosphere, which is thick with carbon dioxide, according to Langbroek from Delft University of Technology in the Netherlands.

Experts are skeptical about the longevity of its parachute system. Additionally, heat shields might have deteriorated over extended periods in orbit.

Jonathan McDowell of the Harvard Smithsonian Astrophysical Observatory mentioned in an email that while the spacecraft would benefit from an intact heat shield, if it manages to re-enter successfully, “a half-ton metal object will be falling from the sky.”

The spacecraft is projected to re-enter around 51.7°N and 51.7°S, passing near London, Edmonton, Alberta, and Cape Horn, South America. However, given that much of the Earth is covered by water, “the chances are favorable.”

    <p>Researchers have identified a unique type of cell division that enables cells to store information in a way that determines the identity of their offspring. This discovery is key to advancing tissue engineering techniques and deepening our comprehension of cancer progression.</p>
    <p>Traditionally, it was believed that the majority of cells would curl into a spherical shape prior to division, allowing for an even distribution of contents between the "daughter" cells and ensuring they remain of the same type.</p>
    <p>However, stem cells represent an exception, as they can undergo heterogeneous or asymmetric cell division, yielding two distinct types of cells.</p>
    <p>In a surprising find, <a href="https://research.manchester.ac.uk/en/persons/shane.herbert">Schoen Herbert</a> from The University of Manchester, along with his team, observed that non-stem cells in developing zebrafish blood vessels also divide asymmetrically. These endothelial cells migrated to form new vessel branches and divided without adopting a spherical shape, resulting in different cell types.</p>
    <p>By altering the shape of human endothelial cells in laboratory conditions, the team established that a cell's geometry can predict the symmetry of its division. Longer, more slender cells were more likely to divide asymmetrically, indicating that the division process can be influenced by the cell's shape.</p>
    <span class="js-content-prompt-opportunity"/>
    <p>Herbert illustrated that cells do not lose their structural and behavioral information during this process, suggesting they maintain their form, thereby preserving their "memory." "Often, they retain their shape, enabling them to convey this memory," he stated.</p>
    <p>This phenomenon allows for a simultaneous movement, division, and production of various cell types without disrupting the ongoing cellular processes. Such flexibility supports rapid adjustments to developmental needs, like supplying tissues necessary for expanding blood vessels and nerves.</p>
    <p>The implications of this discovery extend to lab-grown tissues, where generating functional blood vessels is a significant hurdle. "Our challenge is to create a specific environment that allows these cells to achieve the shapes and behaviors necessary for forming functional blood vessels," explains team member <a href="https://research.manchester.ac.uk/en/persons/holly.lovegrove">Holly Lovegrove</a> from the University of Manchester. Adjusting cell shapes could pave the way for producing specific cell types, she suggests. Conversely, cancer can spread through the formation of clusters of migrating cells, with these new insights potentially shedding light on that process.</p>
    <p>This research exemplifies how organisms can fine-tune mechanisms like cell rounding to accomplish multiple tasks critical for tissue development. <a href="https://www2.mrc-lmb.cam.ac.uk/group-leaders/a-to-g/buzz-baum/">Buzz Baum</a> from the MRC Institute of Molecular Biology in Cambridge, UK, remarked, "This is a clever method to retain essential information while facilitating network growth by generating more cells."</p>

Why Do Many AI Companies’ Logos Resemble Batoll?

Feedback presents the latest updates in science and technology from New Scientist. We encourage you to email Feedback@newscientist.com with intriguing items you think our readers would enjoy.

Is It Really a Flower?

In recent years, the landscape of AI companies has exploded, leading to a mix of excitement and surprise (depending on your early stock investments). However, this influx has also resulted in a surge of nearly identical logos among these companies.

A fascinating observation made by multiple publications is the prevalence of similar designs in these logos. Sociologist James I. Bowie writes for Fast Company about how the trend has shifted towards “stylized hexagons” with an implicit rotation. He notes that these designs evoke a “portal to a mysterious new world,” suggestive of “the expansion of Yetian Gaia,” and humorously, “toilet flushing.”

On a similar note, Radek Sienkiewicz, a developer at VelvetShark, observed that most of these logos share common features: circular shapes, a focal point at the center, radiating elements, and soft organic curves. He refers to this phenomenon as an “apt explanation” for its resemblance to a “butthole“.

Feedback analyzed logos for companies like OpenAI, Apple Intelligence, and Claude, and noted their resemblance to anatomical features more than you might expect. Exceptions like DeepSeek and Midjourney, whose logos depict a whale and a yacht, stand out, but they may soon succumb to the trend of circular designs.

What’s behind the proliferation of stylized hexagons? Perhaps they symbolize the recursive nature of thought, reflecting AI’s capacity to enhance our comprehension of the world.

However, OpenAI offers a different perspective. Their branding guidelines describe their company logo as a “flower,” designed deliberately to avoid any interpretations associated with openings. The logo symbolizes the dynamic interplay between humanity and technology, merging the fluidity of human-centric design through circles with the precision needed for technological structures, allowing for creative freedom.

Personally, Feedback proposes a working hypothesis regarding these logos, invoking the concept of “GroupThink.”

The Challenging Second Album

One of my favored areas of inquiry is the notion that “it’s a common understanding, yet there’s an obvious counterargument that people are either aware of or not.” Thus, we found it pertinent to explore Musical Psychology, focusing on the “Second Album Slump,” where musicians’ sophomore albums often fail to measure up to their debut releases.

This research was originally published last November, highlighting these trends. As noted by science writer Philip Ball on Bluesky in April, and here we are in May finally addressing this topic. Feedback is nothing if not timely.

The study claims it is “the first comprehensive multistudy analysis aimed at discerning the existence of a second-album slump.” The authors analyzed over 2,000 reviews and feedback from more than 4,000 fans. The results indicated a decline in album quality ratings throughout artists’ careers, with significant dips noted in critic reviews during the second album phase.

This raises discussions surrounding the causes: Is it cognitive bias at play? Or is there a “return to the mean”? A standout debut album is an anomaly that garners disproportionate attention, yet subsequent efforts typically don’t replicate that success due to random chance. Furthermore, this notion can be traced back, as Elvis Costello noted as early as 1981: “I had 20 years to write my first album and six months to pen my second.”

It’s important to note that the second-album slump is merely a statistical trend. Numerous artists have released second albums that surpass their debuts, such as Black Sabbath, Led Zeppelin, and Nirvana—alongside Beastie Boys, Pixies, and Taylor Swift. There’s a broader response to Ball’s observations.

Moreover, Feedback wonders whether this second-album phenomenon is confined to rock and pop genres, or if it similarly affects less mainstream styles. Are composers of acid jazz and ambient music also facing second-album challenges? If so, how can we recognize this?

Unusual Smuggling

Executive Editor Timothy Level recently flagged an intriguing report from Reuters regarding a smuggling plot on April 15th.The article describes how four smugglers were apprehended attempting to traffic thousands of live ants from Kenya, including the giant African harvester ant (Messor cephalotes). This species has garnered significant interest among ant enthusiasts, with a single queen fetching nearly £100.

While serious, Tim wanted to highlight a particular detail: the article mentions the “source of the ant trade” concerning the necessary documentation for the legal export of M. cephalotes from Kenya. The trade is described as a “small world,” and thus this individual was “requested not to be named.”

The Top New Sci-Fi of May 2025 Includes an Uplifting Dining Tale by Gracechan

Bora Chong’s Red Sword is set on a planet of conflict

Although there are no blockbuster science fiction releases for May, several remarkable titles stand out. All Versions of Yours is a book I want everyone to read. This month also features two intriguing sci-fi thrillers by Adam Oevani and Burnaby Martin, but it’s Catherine Chidsey’s eerie Guilt that has captivated me enough to consider it my next read—unless I get sidetracked by a narrative of warfare on an alien planet inspired by the true history of Boracheon, Red Sword.

Set in Australia during the late 21st century, this novel (originally released in Australia in 2022 but now gaining broader distribution) tells the tale of Taoi, who lives in a world where most people immerse themselves in a virtual reality called Gaia. Each day, she enters Gaia from her apartment pod to work. The real world is a grim place riddled with relentless heat, devoid of trees and wildlife. This chilling future vision prompts her partner Navin to consider uploading himself to Gaia permanently, seeking an escape as his physical body deteriorates. Taoi, however, is conflicted. This is currently my favorite read—an engaging, thought-provoking sci-fi narrative that lingers in my mind. Watch out, New Scientist Book Club: this might be a selection for us later this year!

I enjoy speculative thrillers, and this one examines the scars left by the Atlantic slave trade. The story kicks off with an unexplainable death – a man found 1600 km from any ocean, while his son appears to have drowned. Detective Ethan Kroll delves into the mystery, uncovering details about Abi Eniola, who claims to be an ordinary Nigerian woman, although her extraordinary skills and high-tech tools suggest otherwise.

On the disputed planet, women are compelled to battle for POWs, revealing a “truly alien landscape” that exposes scientific hatred and the truth about her identity and her fellow captives. Bora Chong draws upon real history to create this narrative, particularly the Korean soldiers who fought for the Qing Dynasty against Russia. It seems like a must-read!

Requiem unfolds in a moon-sized graveyard in space

Another riveting sci-fi horror piece comes from former president of the Association of Horror Writers, John Parisano. Set within the lunar cemetery of Eden, this story follows entities in the universe reclaiming the souls of the deceased. A spirit named Roland must fight to protect what he loves as their souls are threatened.

I’m also intrigued by never let me go, which reimagines England in 1979, where triplets Vincent, Lawrence, and William reside in a government-run facility known as the Sycamore scheme. They are monitored by three figures: morning, afternoon, and night mothers, recording their every move and keeping meticulous notes of their dreams and sins. As the government begins shutting down these homes, the children start to realize their lives might differ drastically from what they’ve been led to believe. I can’t wait to uncover the mystery of this tale.

This upcoming novel is being labeled speculative fiction, suggesting it isn’t traditional fantasy or science fiction, but it definitely piques my interest. The story revolves around Lina and her father arriving at a peculiar seaside building with a “time-made” design that symbolizes a clash between past and future. There, they meet an excommunicated 17th-century Jewish scholar and poets from the Tang Dynasty. What brings Lina and her father to this location?

As a reader, I’m often drawn to narratives focusing on mothers trying to protect their children in perilous futures. This one involves a world of extreme heat, forcing people to live nocturnally, with a mysterious sound field that has loomed for two decades. Scientist Hanna, once affiliated with Soundfield, must now safeguard her gifted son, Isaac.

In a grim future filled with raging wildfires, Iris, a hotelier in the German spa town of Badheim, believes the arrival of a young mother and daughter guests poses a significant threat.

I find the pitch for one novel appealing: “Boy Meets Girl Meets AI Therapist.” Adrian begins using Sike, an AI psychotherapy app designed to monitor users’ emotions and behaviors for optimal mental well-being. He becomes entangled with venture capitalist Maquie, keen on the next tech breakthrough, but she refuses to engage with Sike.

There’s nothing better than a good alien insect…

Victor Zastolskiy/Alamy

Jeff’s ordinary existence is upended when he encounters “a pale woman”; suddenly, he finds himself as a mercenary battling alien insects on the front lines. This intriguing premise is from the publisher of Joe Haldeman’s military sci-fi novel, Eternal War—a title I’m eager to explore, especially given my fascination with alien insects.

How Nearly a Century of Happiness Research Unveiled a Key Finding

When Lyubomirsky joined Stanford’s Graduate School of Social Psychology in 1989, the study of happiness was just beginning to earn respectability in academia. Ed Diener, a psychologist at the University of Illinois at Urbana-Champaign, would later gain recognition for his contributions to the field. Despite his long-standing interest in happiness, he chose to wait until he achieved tenure before diving into the subject. Similarly, Lyubomirsky was hesitant to specialize in happiness; as a serious scientist, she felt that topics related to “emotion” were often regarded as less rigorous. However, after an engaging discussion with her advisor on her first day at Stanford, she resolved to make happiness her primary focus.

Lyubomirsky began by exploring the fundamental question of why some individuals experience greater happiness than others. A few years prior, Diener had published a survey that examined existing research, highlighting the types of behaviors often associated with happy individuals. However, the studies often yielded conflicting results, leading to a lack of definitive answers. Lyubomirsky’s own findings indicated that mindset plays a significant role; happy individuals tended to avoid comparing themselves to others, held positive views of those around them, made fulfilling choices, and did not dwell on negativity.

Yet, Lyubomirsky recognized the complexity of cause and effect. Did a happy disposition foster a healthy mindset, or did adopting a positive outlook lead to increased happiness? Were people inherently predisposed to a certain level of happiness, much like mothers clustering together? She pondered whether it was possible to shift one’s mindset, noting that such changes often required extensive time—many people spend years in therapy attempting to achieve this, often without success. This prompted her to investigate whether simpler, quicker actions could enhance well-being.

To this end, Lyubomirsky researched various habits and practices thought to uplift mood, such as random acts of kindness and expressions of gratitude. Over six weeks, she instructed students to perform five acts of kindness each week—like donating blood or assisting peers with assignments. By the end of the study, these students reported higher levels of happiness compared to a control group. Another group reflected weekly on things they were grateful for, such as “My Mother” and “AOL Instant Messenger,” and similarly experienced an increase in happiness. Although the changes were modest, Lyubomirsky found it intriguing that small, low-cost interventions could enhance students’ quality of life. In 2005, she published a paper asserting that individuals possess significant control over their happiness.

Lyubomirsky’s research emerged during a time when psychology was reevaluating its objectives and focus. When Martin Seligman, a psychologist from the University of Pennsylvania, took leadership of the American Psychological Association in 1998, he and his colleagues noted that the field had overly concentrated on dysfunction, neglecting the promotion of life satisfaction. He urged his peers to explore themes such as “optimism, courage, work ethic, resilience, interpersonal skills, pleasure, insight, and social responsibility,” advocating a return to making life more fulfilling and productive for everyone.

The Massive Meteorite Impacted Northwest Scotland 990 Million Years Ago.

Recent research by Curtin University reveals that an ancient influence, previously believed to have occurred 1.2 billion years ago, actually took place 990 million years ago, leading to the formation of the STAC FADA member. This discovery corrects the dating of some of the UK’s oldest non-marine microfossils and their significance in the timeline of eukaryotic colonization on land.

“We utilized small zircon crystals as geological ‘time capsules’ to accurately date the impact at 990 million years ago,” stated Professor Chris Kirkland from Curtin University.

“These tiny crystals recorded precise moments of impact, some transforming into the rare mineral Reidite, which forms under extreme pressure.”

“This provided irrefutable evidence that the meteorite strike initiated the STAC FADA deposit.”

“When a meteorite strikes, it partially resets the atomic clocks within the zircon crystal. Although these ‘broken clocks’ can’t generate dates, they developed a model to reconstruct timing, affirming the impact’s occurrence 990 million years ago.”

The impact events coincided with the earliest emergence of freshwater eukaryotes, the ancient precursors to plants, animals, and fungi.

“The new date indicates that these life forms in Scotland appeared roughly at the same time as the meteorite impact,” Professor Kirkland remarked.

“This presents intriguing questions about whether significant impacts could have affected environmental conditions, potentially influencing early ecosystems.”

“The impact crater has yet to be located, but this study has gathered additional clues that may eventually uncover its position.

“Understanding the timeline of meteorite impacts will enable us to explore their potential effects on Earth’s environment and the diversification of life beyond the oceans.”

The team’s findings will be published in the journal Geological.

Fossils of Terrestrial Apex Predators Dating Back Six Million Years Unearthed in the Dominican Republic

A recent study conducted by the Florida Museum of Natural History reveals that this apex predator is a type of Cebucid crocodile with origins in South America.



The Cebushid crocodile ruled the South American landscape after the dinosaurs vanished, remaining dominant until roughly 11 million years ago. Image credit: Jorge Mackey.

The sebecids were the last survivors of notosuchia, a large and varied group of extinct crocodiles with fossil records that trace back to the era of dinosaurs.

Notosuchians exhibited a wide range of sizes, diets, and habitats, distinguishing themselves from their alligator relatives, as most inhabited terrestrial environments.

The Sevecid behaved like a carnivorous dinosaur, sprinting with four long, agile limbs and tearing flesh with its notorious teeth.

Some species were equipped with protective armor made of bone plates embedded in the skin, reaching lengths of up to 6 m (20 feet).

The catastrophic mass extinction at the end of the Cretaceous period, which eradicated non-avian dinosaurs, also nearly led to the extinction of the notosuchians.

In South America, only the Sevecids survived post-dinosaurs, quickly ascending to the role of apex predators.

The open waters separating the Caribbean islands from the South American mainland posed significant challenges for the Sevensids when it came to swimming.

In a new research effort, paleontologist Jonathan Bloch and his colleagues from the Florida Museum of Natural History analyzed vertebrae from fossilized teeth and spinal vertebrae dating back six million years, collected from the Paleopoultry 1 site in Savanna Grande de Boya, Dominican Republic.

“Our first question upon discovering these teeth in the Dominican Republic and other Caribbean islands was: what could they be?” Dr. Bloch mentioned.

The team also examined 18 million-year-old teeth found in Cuba and 29 million-year-old specimens from Puerto Rico.

“The fossils suggested evidence supporting the Girllandia hypothesis,” they noted.

This theory posits that a temporary land bridge or chain of islands enabled the migration from South America to the Caribbean.

“If the serrated teeth found in other Caribbean islands also belong to the Sevecid, the history of these giant reptiles stretches beyond just the Dominican Republic.”

“They would have played a significant role in shaping the ecosystems of this region for millions of years. However, today, evidence of large terrestrial predators is scarce.”

“In their absence, smaller endemic predators like birds, snakes, and crocodiles have evolved to fill gaps in the food chain,” he added.

“We could not have predicted this just by studying modern ecosystems,” Dr. Bloch remarked.

“The presence of large predators greatly differs from our previous assumptions, and it’s thrilling to explore what further discoveries might await in the Caribbean fossil record.”

The team’s paper was published in Proceedings of the Royal Society B.

Judge Rules Men Accused of Hacking Can Be Sent to U.S. for Trial

A British court has approved the extradition of an Israeli individual charged by a New York prosecutor in a case involving an operation dubbed “hacking fatalen,” aimed at environmental organizations.

According to prosecutors, the company operated by 57-year-old Amit Forlit allegedly earned over $16 million by hacking more than 100 victims and stealing confidential data while working for major oil companies on behalf of a lobbying firm.

In a court submission from January, Forlit’s attorneys identified the company as ExxonMobil. Exxon is currently facing lawsuits from Democratic lawyers and local officials regarding its role in climate change, with claims that it has concealed knowledge about climate change for decades to maintain its oil sales. The lobbying firm mentioned in the filing is known as DCI Group.

Exxon has stated that it was not involved in and had no knowledge of the hacking activities, emphasizing, “If hacking is involved, we will condemn it in the strongest possible terms.”

A spokesman for DCI, Craig Stevens, stated that the firm has instructed its employees and consultants to follow the law and asserted that none of DCI’s guidance was linked to the hack that allegedly occurred a decade ago.

DCI also referred to “numerous billionaire donors still benefiting from the fossil fuel legacy,” describing them as “financiers of radical anti-oil activists and their billionaire backers.”

This remark hinted at the Rockefellers’ involvement in supporting organizations pursuing climate change litigation. The Rockefeller heirs, who amassed oil fortunes over a century ago, lead the Rockefeller Family Fund, which plays a significant role in the movement to sue oil companies over climate change. Lee Wasserman, its director, has reported being targeted in a hacking initiative.

Last year, Forlit was arrested in connection with a major trial in New York for allegedly committing wire fraud, conspiracy to commit wire fraud, and hacking offenses that could lead to lengthy prison sentences. His legal team contended that he should not be extradited due to concerns about a fair trial in the U.S., given the political climate surrounding climate change litigations.

They argued that “one motive for the prosecution appears to be an effort to advance political agendas against ExxonMobil, with Forlit being collateral damage.”

Forlit’s attorneys also expressed concerns about his safety at the Metropolitan Detention Center, New York’s only federal prison, which has been criticized for violence and dysfunction. High-profile detainees have included individuals such as Luigi Mangione, Sam Bankman-Fried, and Shawn Combs (Puff Daddy/Diddy).

The Westminster Magistrate’s Court dismissed these worries, but Forlit has the option to appeal. His attorney did not immediately respond to inquiries for comments.

One targeted entity was a coalition of concerned scientists who have extensively researched the fossil fuel industry’s influence on climate science disinformation. This group also engages in source attribution science, estimating how specific companies contribute to global warming effects like rising sea levels and wildfires. Their findings support lawsuits against the oil sector.

The organization became aware of hacking attempts following a 2020 report from Citizen Lab, a cybersecurity watchdog from the University of Toronto, which revealed that hackers were targeting American nonprofits working on the #ExxonKnew campaign.

A coalition of concerned scientists has received suspicious emails in which hackers attempted to extract passwords or deploy malicious software. Prosecutors from the U.S. Attorney’s Office in the Southern District of New York have initiated an investigation.

One of Forlit’s associates, Aviram Azari, pleaded guilty in New York to charges including computer breaches, wire fraud, and identity theft, receiving a six-year prison sentence.

Forlit manages two Israel-registered security and intelligence newsletter firms, one of which is registered in the U.S. His clientele includes a lobbying firm representing “one of the world’s largest oil and gas companies” involved in ongoing climate change litigation. Exxon has its historical roots in Irving, Texas.

The lobbying firm selected targets for Mr. Forlit, who then passed the list to Azari. Azari, who owned another Israeli-based company, employed individuals from India to gain illegal access to accounts. This information was reportedly utilized to gather documents from oil companies and the media, allegedly undermining the integrity of the civil investigation, according to the filings.

Microplastics Could Impair the Ocean’s Carbon Capture Capacity

Microplastics are not merely present on the ocean’s surface. A comprehensive study on small particles has shown their widespread presence throughout the water column, potentially impacting the ocean’s capacity to sequester carbon from the atmosphere.

“There are countless entities like this all across the ocean’s interior,” states Tracy Mincer from Florida Atlantic University.

Mincer and his team analyzed microplastic data collected over the last decade from nearly 2,000 global locations. While many assessments concentrate on shallow ocean surfaces, their dataset incorporated samples from various depths, including some of the ocean’s deepest regions.

The researchers found microplastics documented precisely where research efforts were focused. This includes the Mariana Trench, where more than 13,000 microplastic particles were recorded, nearly 7 kilometers per cubic meter.

They were taken aback by the uniform distribution of the smallest particles throughout the water column. “While we anticipated finding plastics at both the ocean’s surface and its depths, they were unexpectedly widespread,” remarked Aron Stubbins from Northeastern University, Massachusetts.

Additionally, these plastic polymers contribute significantly to the carbon particles present in the water. At a depth of 2,000 meters, an area less biologically active than the surface, they account for 5% of the carbon content.

The ecological ramifications of these findings are not yet fully understood. One major concern is that buoyant plastics consumed by plankton may decrease the amount of carbon that is effectively transported to deeper layers through fecal pellets and carcasses. This could impede the ocean’s biological carbon pumps, says Stubbins. However, he emphasizes that quantifying the impact of this phenomenon remains a challenge. “We are uncovering a variety of plastics throughout the ocean,” he notes.

“We can no longer afford to overlook the insights of chemists and biologists in understanding how vast ocean systems operate,” stated Douglas McCauley from the University of California, Santa Barbara. He believes this research will clarify the discrepancies between estimates of millions of tons of plastic entering the oceans and the actually measured quantities. “Sadly, it’s not vanishing. Instead, it has dispersed throughout the water as microplastics,” he adds.

Medications Similar to Wegovy Show Effectiveness in Treating Fatty Liver Disease

Fatty liver disease can lead to cirrhosis and cancer

3dmedisphere/shutterstoc k

Currently, common medications used for treating obesity and diabetes are showing promise in combating life-threatening liver diseases.

Semaglutide, marketed under names like Ozempic and Wegovi, mimics the hormone GLP-1, which aids in weight loss and regulates blood sugar levels, helps suppress appetite, and promotes insulin secretion. Researchers have now found that this drug therapy can halt or even reverse a condition known as metabolic dysfunction-associated steatohepatitis (MASH).

“This could offer a groundbreaking way to manage this condition,” says Philip Newsom from King’s College London. “It’s incredibly promising for patients.”

MASH, formerly known as NASH, is a severe version of non-alcoholic fatty liver disease marked by inflammation, fibrosis (scar tissue formation), and excessive liver fat accumulation, occasionally leading to cirrhosis and cancer. MASH is commonly linked to obesity and often coexists with type 2 diabetes.

A study conducted in 2020 involving 320 participants revealed that daily semaglutide injections led to a reduction in liver fat and inflammation in 59% of those with MASH. However, a more recent investigation involving 71 patients found no benefits from the weekly dosage.

For a broader perspective, Newsom and Arun Sanyal from Virginia Commonwealth University initiated a larger trial involving 1,195 MASH patients across 253 clinical sites in 37 countries. Participants averaged 56 years old with a body mass index of 34.6, and about 50% had type 2 diabetes.

The physician prescribed each participant a weekly semaglutide injection for four and a half years, gradually increasing the dose to 2.4 milligrams over the first four months, mirroring those used in Wegovy based on prior test findings. Participants also received lifestyle counseling to encourage a healthier diet and exercise.

While the full study is ongoing, results from biopsies taken 72 weeks later revealed that among the first 800 patients, including 266 receiving a placebo, 62.9% of those on semaglutide showed significant reductions in liver fat and inflammation, compared to 34.3% in the placebo group. Improvements in fibrosis were observed in 36.8% of the treatment group versus only 22.4% for the placebo group. About one-third of all treated patients and 16.1% of placebo patients experienced these benefits.

Weight loss alone could explain some of these improvements, as patients in the treatment cohort lost an average of 10.5% of their body weight, while those on the placebo lost only 2%. Although further research is needed to fully uncover the mechanisms behind the treatment, it may also directly target the processes driving the disease.

“It’s not yet established, but part of the efficacy of GLP-1-like drugs might be due to their effects on immune cells and reduction of inflammation,” notes Newsom.

Extraordinary Claims Demand Extraordinary Evidence

Stepping into the Royal Society of London, the UK’s foremost National Academy of Sciences, you’ll encounter a three-word phrase: Nullius in Verba. This motto, held for over 350 years, translates to “I accept no one’s word.” Essentially, trust in science must be based on empirical evidence.

But what qualifies as evidence? This aspect becomes a bit more nuanced. The assertion that the sky is blue can be easily substantiated by anyone who can see it; therefore, little further proof is necessary. However, if someone claims the sky is purple, we’d need a robust explanation for our apparent oversight.

Another famous saying, attributed to astronomer Carl Sagan, encapsulates the demand for solid evidence: “Extraordinary claims require extraordinary evidence.” This issue highlights several notable recent examples that fall short of that standard.

The first example resonates strongly with Sagan’s perspective. Recently, astronomers proposed they detected gases potentially indicative of extraterrestrial life in distant exoplanets, but subsequent analysis suggests they may have found nothing. There’s also a significant backlash from biotechnology firm Colossal against the International Union for Conservation of Nature, alleging it “clears” threats to the wolf population.

The work of science is, as always, to dig deeper in hopes of revealing the truth.

There is considerable excitement surrounding these claims, with many hoping they prove true, but unfortunately, they do not hold up. We are committed to accurately reporting substantial claims, as seen in our discussion about the assertion that light is not subject to wave-particle duality, but consists solely of quantum particles.

This is indeed an extraordinary claim, challenging a century of established physics. As we explore, the evidence to substantiate this notion is currently lacking, though physicists remain intrigued enough to pursue further investigation. Without clear evidence disproving the claim, the essence of scientific inquiry remains: to dig deeper in hopes of uncovering the truth or, at the very least, our best approximation.

Your Washing Machine Might Not Eliminate Harmful Bacteria from Your Clothes

Is your washing machine providing a thorough clean?

Aquaarts Studio/Getty Images

Washing clothes in warm water at 60°C (140°F) might not effectively eliminate harmful bacteria.

Studies indicate that contaminated fabrics can remain infectious for weeks. Moreover, washing with detergent at 60°C can remove bacteria and tackle stubborn stains.

For example, NHS England advises healthcare workers to wash uniforms at 60°C for a minimum of 10 minutes to eliminate nearly all microorganisms, according to Katie Laird from De Montfort University in Leicester, UK. “However, it’s unclear what the machine is truly accomplishing.”

Laird and her team examined six models of home washing machines to evaluate how effectively they cleaned contaminated fabric samples, specifically testing for Enterococcal feces, known to cause various infections, including urinary tract infections.

Their findings revealed that half of the washing machines tested failed to adequately disinfect clothing, reducing bacteria levels by at least 90% in only the rapid cycles; one-third of machines did not achieve sufficient breakdown even in standard cycles.

“This is primarily because most machines either don’t maintain or reach the expected temperature, particularly in shorter cycles,” notes Laird. “In one instance, we found a machine operating at just 20°C (68°F), which the user was unaware of.”

After analyzing bacteria across multiple washes, Laird’s team discovered that microorganisms began developing resistance to detergents. DNA sampling indicated that these microorganisms were acquiring genes that enabled their survival.

The findings suggest that utilizing home washing machines to launder medical uniforms could inadvertently facilitate the spread of infections and antibiotic resistance within hospital settings, Laird pointed out.

To reduce bacteria and viruses in household washing machines, Laird recommends regularly using a machine sanitizer, conducting 90°C (194°F) cleaning cycles, and employing descaling solutions to prevent the build-up of scale that may impair the heating elements’ function.

Genome Sequencing by BlackBerry Researchers

Researchers at the University of Florida have successfully generated a chromosomal-scale genomic assembly for the spinless tetraploid blackberry BL1, which is primocanfluting. Their findings are expected to serve as crucial resources for accelerating genetic analysis in blackberries and fostering the development of new, enhanced varieties that improve horticultural and nutritional attributes.

Blackberries belong to the genus Rubus, subgenus Rubus (formerly subgenus Eubatus) within the Rose family.

These fruits are noted for their rich dark purple to deep black colors, complex fruit structures, and a delightful balance of tartness and sweetness.

Blackberry fruits are a significant source of anthocyanins, antioxidants, and dietary fiber, offering numerous health benefits to consumers.

In the last two decades, a surge in consumer interest has greatly expanded the market for fresh and processed blackberries in the United States and internationally.

As the fourth most economically significant berry crop in the U.S., the nation produced 16,850 metric tons of processed blackberries and 1,360 tons of fresh blackberries in 2017.

In 2021, the U.S. imported 122,873 metric tons of fresh blackberries and 16,738 tons of frozen blackberries, valued at $519 million and $43 million, respectively.

Global blackberry production is estimated to exceed 900,000 metric tons, playing a crucial role in the international berry market.

The ongoing development and introduction of improved varieties continue to drive consumer demand and enhance blackberry production worldwide.

“This new research not only deepens our understanding of blackberry genetics but also lays the groundwork for significant advancements in blackberry breeding techniques,” says Dr. Zhanao Deng, PhD, in the journal Horticulture Research.

“The ultimate goal is to create a superior, more resilient blackberry variety that benefits both growers and consumers globally.”

Utilizing a comprehensive collection of DNA sequences from the experimental BlackBerry BL1, Dr. Deng and his team meticulously calculated and reconstructed the original sequences across the blackberry genome.

It begins with recognizing that BL1 is a tetraploid fruit, which derives from a plant possessing four copies of each chromosome within its cells.

This characteristic results in twice as many chromosomes compared to typical diploid plants such as raspberries.

“Working with tetraploids is more complex than with diploids,” Dr. Deng remarked.

“The release of the tetraploid blackberry genome can facilitate more efficient and targeted breeding, ultimately enhancing fruit quality and leading to the creation of new varieties resilient to critical diseases.”

“The reference genome derived from this study will serve as a powerful tool for researchers working with blackberries.”

The genome assembly also unlocks insights into key traits such as the cultivation of spinless blackberry plants and the processes behind anthocyanin production, which influences the color and health benefits of the fruit.

“This discovery helps us understand why blackberries attain their distinctive deep purple/black hues over time and how we might potentially improve this process for more nutritious berries,” Dr. Deng added.

The team’s research is published in the journal Horticultural Research.

Early Monotonicity: A Semi-Quantitative Discovery by Paleontologists

The prevailing belief regarding these egg sales has been that both species descend from land-dwelling ancestors. While the ancestors of the platymonds became semi-aquatic, Echidna remained terrestrial. However, a detailed examination of a humerus bone from Kryoryctes cadburyi, a prehistoric monotreme that lived in Victoria, Australia, during the early Cretaceous period, indicates that Echidna evolved from semi-aquatic ancestors, suggesting that the lifestyle of modern paddy field amphibians originated over 100 million years ago.

“Approximately 30 examples of mammals have evolved to live entirely or partially in water, such as whales, dolphins, dugongs, seals, otters, and beavers,” says Professor Suzanne Hand, a paleontologist from the University of New South Wales.

“However, it is exceedingly rare to observe mammals evolving in the opposite direction.”

“We are discussing semi-aquatic mammals that transitioned to a land-based existence. Such an event would be quite unusual, but I believe that’s what occurred with echidnas.”

In their recent study, Professor Hand and her team analyzed a single humerus bone of an ancient monotreme, Kryoryctes Cadbury.

Using CT scans and other techniques, they investigated the internal microstructure of the specimen.

“The external structure of bones allows for direct comparisons with similar animals to clarify relationships, while the internal structure offers insights into the beast’s lifestyle and ecology,” Professor Hand explained.

“Thus, while the internal structure might not reveal the animal’s identity, it can inform us about its environment and living conditions.”

Living in southern Victoria about 108 million years ago, Kryoryctes cadburyi and its relatives dominated the Australian mammalian fauna.

“Mesozoic mammals from Australia are uncommon and primarily known through their teeth and jaws,” states Professor Michael Archer from the University of New South Wales.

“Currently, Kryoryctes cadburyi is known solely from limb bones.”

“This humerus presents an extraordinary chance to gain insight into the lifestyles of Australian mammals, revealing a considerable story, perhaps one we weren’t initially anticipating.”

Researchers were taken aback when they discovered that the internal structure of the ancient humerus differed from that of modern Echidna bones.

“The internal structure shows that the bone wall of platymonds is quite thick with a narrow bone marrow cavity, while Echidna has a much thinner bone wall,” they noted.

“The fine structure of the Kryoryctes cadburyi humerus resembles that found in lizards, with its dense bone serving as ballast, aiding its ability to dive for food, a trait noticed in other semi-aquatic mammals.”

There are also peculiar traits in modern Echidna that might hint at an ancient semi-aquatic ancestry.

“It’s well established that the platypus bill contains numerous highly sensitive receptors that detect slight currents created by prey,” Professor Hand remarked.

“Although Echidna’s snouts have fewer receptors, it’s thought these might be remnants of their aquatic manipulative capabilities, along with traces of platypus-like features found in the embryos of echidnas.”

“Another characteristic inherited from their aquatic ancestors is the backward orientation of Echidna’s hind legs, similar to the rounded feet of the platypus when swimming.”

“In Echidnas, however, this trait is utilized for digging.”

“Our research has shown that echidnas exhibit diving reflexes when submerged in water, which assist in conserving oxygen and prolonging breath-holding capabilities. Studies on a respiratory protein called mammalian myoglobin further suggest echidna’s semi-aquatic ancestry.”

“The positive charge on myoglobin’s surface correlates with enhanced muscle capacity to retain oxygen, thereby extending the duration mammals can dive.”

“This is more prominent in platypuses, but even among burrowing mammals, echidnas show a higher than expected capacity.”

Survey results were published this week in Proceedings of the National Academy of Sciences.

Two Theories of Consciousness Conflict: The Referee Took a Major Hit.

While the nature of consciousness may remain elusive, neuroscientists have made significant strides in understanding it. The journey is far from over.

“Numerous theories exploring consciousness exist, so further theories may be superfluous,” states Oscar Ferrante, a neuroscientist at the University of Birmingham.

If you seek an explanation for how our brains create subjective experiences, you might explore adaptive resonance theory or dynamic core theory. Additionally, the theory of primary expression and semantic pointer competition should not be overlooked. A 2021 survey identified 29 distinct theories of consciousness.

Dr. Ferrante is part of a group aiming to consolidate this proliferation of theories. Yet, they face challenges due to the typical approach scientists take towards consciousness studies. They propose theories, conduct experiments, gather evidence, and often claim their theory reigns supreme.

“We are discouraged from abandoning our ideas,” remarked Lucia Meloni, a neuroscientist at the Max Planck Institute for Empirical Aesthetics in Frankfurt, Germany.

Seven years ago, Dr. Meloni and 41 other scientists launched an extensive study on consciousness to break this cycle. Their goal was to unite rival groups to design an experiment that would assess the predictive power of both theories regarding conscious experiences in the brain.

The Cogitate Consortium team recently published their findings in Nature. However, this study encountered the same contentious conflicts they aimed to avoid.

Dr. Meloni and like-minded colleagues started planning their research in 2018, adopting a strategy known as hostile collaboration—where scientists with opposing theories partner with neutral researchers. They selected two theories for examination.

The first, known as the Global Neuronal Workspace Theory, was introduced in the early 2000s by Collège de France’s Stanislas Dehaene. This theory posits that our conscious experiences arise when key brain areas distribute sensory information across the brain.

The second theory, Integrated Information Theory, developed by the University of Wisconsin’s Giulio Tononi, does not link consciousness to specific brain regions. Instead, it begins with essential characteristics of conscious experience, such as feeling unique and possessing rich, coherent details. Madeleine.

Researchers then examined which physical networks, such as the brain, could facilitate this experience. They concluded that a substantial amount of information must be processed across various networks and integrated to form a cohesive experience.

The Cogitate Consortium’s experiment aimed to potentially test both theories, garnering support from proponents of both.

“This collaboration was significant as it was the first attempt to reconcile differences rather than engage in isolated pursuits,” noted Dr. Meloni.

However, they knew that hostile collaboration would require substantial effort. They enlisted many young researchers, including Dr. Ferrante, and spent two years designing experiments and setting up lab equipment. By the latter half of 2020, they began scanning the brains of 267 volunteers across eight labs in the US, Europe, and China.

Volunteers played video games designed to gauge their conscious perception. In one game, participants were tasked with catching a colored disc when it changed to striped. Occasionally, blurred faces appeared on the screen, prompting volunteers to indicate what they had noticed.

To capture data comprehensively, researchers employed three distinct methods to measure brain activity.

Some volunteers who had undergone surgery for epilepsy consented to have electrodes temporarily placed in their brains. The second group utilized fMRI to assess blood flow in the brain, while a third group underwent magnetic EEG testing to record the brain’s magnetic field.

By 2022, the researchers shifted focus to data analysis. The three techniques produced consistent results. Both theories made accurate predictions regarding brain activity during conscious experiences, but also had incorrect predictions.

“Both theories are incomplete,” remarked Dr. Ferrante.

In June 2023, Dr. Meloni presented the findings at a New York conference, and the Cogitate Consortium submitted their results for publication, hoping to see their work in print.

Hakwan Lau, a neuroscientist at Sungkyunkwan University, was invited to review the paper but made a critical assessment. He believed the consortium failed to clearly outline where in the brain they would test predictions for each theory.

“Making a compelling case that the project tests theories meaningfully is challenging,” Dr. Lau stated in a July review.

Having developed his own consciousness theory, Dr. Lau published an evaluation online in August, and later co-authored an open letter criticizing both the Cogitate experiments and Integrated Information Theory. A total of 124 experts endorsed the letter.

The group labeled “IIT agree” directed much of its critique at integrated information theory, calling it pseudoscience in a recent analysis.

Critics highlighted that Integrated Information Theory extends beyond just a brain function theory—implying that a system capable of integrating information, even a plant, may possess some level of consciousness.

Critics contended that the Cogitate Consortium’s experiment failed to address the foundational aspects of the theory, thereby not adequately challenging its claims. “As researchers, we must safeguard the public from scientific misinformation,” Dr. Lau and his colleagues asserted.

Their letter, published online in September 2023, ignited a flurry of debate on social media. The authors later provided a commentary to elucidate their concerns, which was featured the following month in Nature Neuroscience.

In response, Dr. Tononi and his colleagues, in a published letter defended IIT, claiming that the critics’ letters were “full of enthusiasm and lacking in facts,” and asserting that the new commentary merely aimed to reshape the discussion.

Meanwhile, the Cogitate Consortium paper continued through the peer review process. Upon its release on Wednesday, it drew a spectrum of responses.

Anil Seth, a neuroscientist at the University of Sussex, expressed admiration for the study’s scale and the identification of shortcomings in both theories. “I’m pleased to see that,” he remarked. “That’s an impressive achievement.”

However, some critics of IIT continued to voice concerns. Joel Snyder, a psychologist at the University of Nevada, Las Vegas, noted that the predictions from each team might have been generated by alternative theories, indicating the experiment wasn’t a true test of either.

“This is likely to cause confusion,” Dr. Snyder commented.

Dr. Lau reflected in an email that the recent research does not appear to have narrowed down the numerous theories of consciousness. “Recent discussions leave me with the impression that these issues haven’t significantly advanced any theory,” he wrote.

Nonetheless, Dr. Seth acknowledged the value of testing competing theories, even if scientists are reluctant to discard their ideas. “The best outcome of a successful hostile collaboration is that it may lead others to reconsider their views,” he stated.

A Diver Explores a Stranded Whale, Only to Discover It Has Vanished Upon His Return.

What happens to an 18-foot long, 2,000-pound body?

This question perplexed divers and photographers who frequently explore the waters off San Diego’s coast.

The saga began this spring when Doug Bonhouse took advantage of the mild weather to scuba dive at Scripps Canyon. As he submerged, a large mass caught his eye beneath him.

At just 115 feet below the surface, he discovered the body of a juvenile gray whale.

Whale carcasses are typically not encountered by human divers; they are usually found by remotely operated vehicles at depths exceeding 3,000 feet.

Local marine biologists speculated about the origins of the gray whale calf. The creature, which was suited to the seabed, had been sighted near La Jolla Shores, desperately searching for its mother. In its final moments, it appeared to approach a boat, as if pleading for assistance.

Other divers quickly made their way to the site, as it was the first opportunity for access during the autumn. Among them was underwater photojournalist Jules Jacobs, who documented his exploration for the New York Times.

By late January, the whale’s resting place was in a canyon valley that required careful navigation to reach. This challenge left Jacobs feeling both anxious and mentally drained.

As Jacobs navigated through the darkness with a team of five divers, the beam from his dive light suddenly illuminated the object of his search: a fragile calf with spotted skin. Its eyes had succumbed to the elements, frozen in an expression of sorrow.

“It’s humbling to swim through a whale’s carcass when only its tail is as large as your body,” Jacobs remarked.

Jacobs planned further dives to study the remains. On his second visit a week later, however, he discovered that the tail was missing, likely taken by scavenger sharks like Seven Gill and Mako.

After a series of spring storms, Jacobs descended again in late February. Gripping his camera gear so tightly that his knuckles turned white, he awaited the sight of the decaying creature.

He was met only by an empty seabed.

The calf was gone.


Adult gray whales can grow to about 45 feet and are known for their extraordinary migrations from the warm waters of Baja, California, to high-latitude feeding grounds in the Arctic Ocean. It’s likely that the calves and their mothers headed north before becoming separated. At this vulnerable point in their journey, the calves would have faced starvation after not eating for six months.

Gray whale populations experience cycles of boom and bust, recovering from significant declines, sometimes losing up to a quarter of their numbers within just a few years.

However, the population has failed to rebound for about six years, mirroring previous downturns. Scientists link this decline to climate change, which accelerates warming in the Arctic and disrupts the whales’ prey availability. Additionally, ship strikes and entanglements further exacerbate mortality rates.

“We are observing a significant increase in fatalities among gray whales,” stated Joshua Stewart, an assistant professor at the Marine Mammal Research Institute at Oregon State University. He anticipates more whale deaths along the West Coast.

Nevertheless, the death of a whale does not necessarily signify an end. Instead, it often triggers new beginnings.

Life flourishes from the remains of whales. Their meat nourishes scavengers, bones become habitats for microorganisms and insects, while the curved vertebrae provide a new foundation for flourishing coral reefs.

“Whale falls are ecological bonanzas, capable of providing sustenance for up to 200 years, as they typically reach the ocean floor,” remarked Craig Smith, professor emeritus of oceanography at the University of Hawaii. “Ironically, we understand more about deep-sea whale falls and associated communities than we do about shallow-water ecosystems.”

Whale decay occurs in three distinct ecological stages. Initially, scavengers like sharks, crabs, and hagfish consume the soft tissue. Next, worms thrive in the nutrient-rich, vibrant masses surrounding the carcass, as Dr. Smith notes; this phase can last up to seven years and is termed an enrichment stage by scientists.

Ultimately, bacteria deep within the bones produce hydrogen sulfide, fueling chemically-chemosynthetic bacteria that thrive symbiotically with the animal hosts and chemically synthesized bacteria on the bone’s surface. This final stage can endure for decades, supporting over 200 marine species within the ecosystem generated by a single whale fall.


However, the calf and its remains had vanished. Was something or someone responsible for preventing the whale fall that would support life?

Gregory Rouse, a marine biology professor at the Scripps Marine Research Institute, considers the matter less enigmatic. He explained that during the whale fall, decomposition within the body cavity can generate gas, causing the body to rise again after initially sinking.

It’s also plausible that strong winds and turbulent currents carried the body deep into the canyon. It could have descended to 1,600 feet below.

“The animal could have grown into a titan, but its life was cut short in infancy,” Jacobs reflected.

However, if it rests quietly in the depths, new life may proliferate and thrive.

What Defines a Kentucky Derby Champion? A Big Heart, Powerful Lungs, and Strong Legs

Horses have honed their abilities, such as running, jumping, and pulling, as humans have bred and trained them for various purposes over thousands of years. The 151st Derby, the most-watched horse racing event, not only highlights the skills of these animals but also raises concerns about their treatment and well-being. Advocates have long voiced worries about injuries and fatalities, especially after twelve horses died at Churchill Downs two years ago.

There’s no doubt that the relationships between humans and horses have transformed warfare, agriculture, and society.

Timothy Winegard, a historian at Colorado Mesa University and author of the recent book, The Horse, remarked, “We’ve combined our intellect with the horse’s size, strength, stamina, and speed to create the most unstoppable animal coalition.”

Why Are Horses So Powerful?

The horse’s heart and lungs contribute significantly to its remarkable power.

Hearts typically weigh between 10-12 pounds (4.5-5.4 kg), roughly 1% of the horse’s body weight, compared to about 0.5% for a typical human heart. The famous horse Secretariat, who won the Triple Crown in 1973, was later found to have a heart weighing over 20 pounds (9.1 kg).

A horse’s heart is designed for exercise, with a resting heart rate around 34 beats per minute that can rise to 220 or 240 during a race—much faster than a human’s maximum during intense exertion.

“One unique aspect of horses is their incredible capacity to circulate blood throughout their bodies. They can achieve high heart rates while remaining safe,” explained Sarah Reed, a researcher at the University of Connecticut.

Additionally, horses possess a lung capacity of 60 liters, ten times that of a human.

“This extensive lung capacity allows oxygen to efficiently transfer from the air to the blood, which is essential for sustaining aerobic energy,” noted Farmer.

Recent research published in the journal Science indicates that genetic mutations enable horses to mitigate the adverse effects associated with ultra-high energy production.

“Horses are exceptional athletes because they can deliver significantly more oxygen to their muscles than elite Olympic athletes. They have larger energy reserves and more efficient systems…and these mutations play a role in both aspects.”

What Contributes to a Horse’s Speed and Skills?

Various biological characteristics enhance a horse’s abilities.

Horses store excess red blood cells in their spleens, which are released to enhance oxygen transport during intense exertion.

“During exercise, adrenaline triggers the spleen to circulate these excess red blood cells,” said veterinarian Hillary Clayton. “Essentially, what a horse accomplishes is a form of ‘natural blood doping.’”

Furthermore, a horse’s brain is adept at processing sensory information and reacting swiftly. Although their frontal lobe—the section associated with thinking and planning—is proportionally smaller than that of humans, horses are hardwired for play and independent running without fear, as explained by Dr. Scott Bailey, a veterinarian at Clayborne Farm. This focus is critical for athletic performance.

The bone structure and muscle makeup are also advantageous. The ligaments and tendons in their hind legs function like springs, and as Farmer noted, like other large prey animals, they possess “long, slender legs designed for running.”

What Are the Risks for Horses?

Adjustments that enhance a horse’s speed also increase the risk of injuries. Their slender legs endure the impact of each stride, and over time, repetitive stress during racing and training can lead to tendon and ligament damage, Reed stated.

In 2023, fatalities occurred not only at Churchill Downs but also at other major racecourses, affecting public perceptions of the sport and prompting changes. No specific cause of death was identified. However, in 2024, Churchill Downs improved the equipment used on its racing surfaces and added a veterinarian dedicated to horse safety and integrity.

Crafting Fashion Accessories Inspired by Real T. Rex Fossils

Eighty million years ago, the formidable 40-foot-long Tyrannosaurus Rex ruled the earth. Now, it may soon inspire a new kind of wallet.

A team of British researchers and bioengineers is working on high-end clutches and totes made from T. rex skin, cultivated from the fossilized remains of ancient carnivorous creatures.

Their goal is to create sustainable leather by extracting collagen from this colossal dinosaur, known to have roamed North America and Asia about 68 million years ago. If they succeed, it would mark the first instance of leather derived from an extinct species.

The project’s developers assert that their lab-grown materials will be entirely biodegradable and structurally identical to conventional leather. Choi Conon, a professor of tissue engineering at Newcastle University, commented on the initiative.

Conon is also associated with a Biotechnology Company. Lab-grown leather is in collaboration with the Dutch creative agency VML and the genomic engineering firm The Organoid Company.

“This opens the door to designing leather from prehistoric origins,” stated Connon, a key leader in the project.

While Connon and his team are targeting the fashion sector, market data providers Fortune Business Insights predicts that the global leather goods market, valued at $500 billion, could reach $85.5 billion by 2032.

However, experts caution that immediate results may not be forthcoming. The commercialization of lab-grown T. rex leather could be financially prohibitive.

According to Tom Ellis, a professor of synthetic genomic engineering at Imperial College in London, the “gimmick” is still “very early.” He noted, “Our understanding of dinosaur evolution may not be sufficient to design collagen genes specifically from T. rex.”

Ellis emphasized that producing authentic T. rex leather is still a long way off, suggesting that any collagen derived from the project would likely resemble that of cows and chickens.

This means the end product may resemble other alternative leathers. “We’ll offer something unique enough to justify a significantly higher price,” he added.

In theory, scientists can extract collagen gene sequences from various animals, as collagen is the most abundant protein in mammals. Companies like Gelter and modern pastures are already crafting leather-like materials from genetically engineered collagen, producing small batches of premium products.

If achieved, sustainably crafted animal leather could have notable environmental advantages. Currently, most leather is a byproduct of the cattle industry, contributing to deforestation in regions like the Amazon. Additionally, many synthetic and vegan leathers are made from fossil-fuel-derived plastics that are not biologically sustainable. According to the World Wide Fund.

As scientists ponder the potential for dinosaur wallets, fashion enthusiasts should take a moment to consider whether they should indulge in such products.

NASA’s Budget Cuts Endanger Wildfire Combat Program

Hinesville, Ga. — From an elevation of 9,000 feet, NASA researchers observed extensive areas of prescribed burns at Fort Stewart Army Base this month, actively monitoring the flames and engaging with the landscape.

This burn is intentional and controlled, conducted as part of “prescription burns” to clear specific regions. The study, part of NASA’s FireSense project, aids firefighters in combating actual wildfires and may even help land managers avoid unnecessary ignitions.

However, initiatives like FireSense may face challenges as reports suggest significant budget cuts for NASA and other federal agencies under the Trump administration.

Last year, the U.S. experienced nearly 9 million acres consumed by wildfires, according to the National Interagency Fire Centre. Their annual report noted that wildfires and burned acreage in 2024 were “significantly higher than the five- and ten-year averages.”

Research indicates that climate change not only increases the frequency of wildfires but also exacerbates their destructiveness.

“The situation is deteriorating,” stated Michele Steinberg, director of the Wildfire Division at the National Fire Prevention Association. “We are witnessing fires in areas previously unaffected, burning hotter than ever.”

Severe wildfires pose substantial health, financial, and environmental threats, highlighting the importance of safeguarding lives and livelihoods through research.

NASA is not the only agency focused on wildfire issues. The U.S. Forest Service, the Department of the Interior, and the Bureau of Land Management are among the key federal entities engaged in wildfire response and prevention. What sets space agencies apart is their application of advanced technologies, including tools used in space, to bridge existing knowledge gaps.

“FireSense emerged from NASA’s recognition of wildfires as a significant issue. We are leveraging our expertise to assist the government in improving its wildfire management efforts.”

Project scientists will collaborate with local, state, and federal agencies, as well as academic partners, to enhance understanding of fire behavior, air quality concerns during and after wildfires, and ecosystem recovery post-ignition. Researchers are also exploring ways to manage vegetation in at-risk areas to minimize wildfire risks and curb rapid spread.

“Our objective is to adopt innovative technology, work closely with Wildland Fire Managers, and ensure this technology is accessible for wildfire situations,” explained Jacquelyn Shuman, a NASA Firesense project scientist.

The project employs equipment designed similarly to instruments used in low-Earth orbit on the International Space Station, providing detailed and accurate metrics to assist firefighters and land managers before, during, and after major fires.

At Fort Stewart, scientists monitored the prescribed burns, documenting the spread and mapping the flames with advanced infrared instruments known as Aviris-3 (short for Airborne Visible/Infrared Imaging Spectrometer 3). The fire ultimately consumed around 700 acres.

Researchers closely monitored fire spread, its ground position, and temperature variations.

Prescription burns are intentionally ignited to manage ecosystems that rely on regular fires for health. They also help diminish dry, combustible vegetation that could ignite uncontrollably.

These burns are meticulously planned and conducted under specific weather conditions to control their spread; they also serve as scientific experiments for wildfire researchers, according to Harrison Raine, a former elite firefighter and current project coordinator for FireSense.

“We’re aiming to integrate all aspects of the fire lifecycle and utilize scientific understanding to address ongoing issues,” said Raine, who has extensive wildfire experience across multiple states.

“This is a profoundly personal issue for me,” he shared. “Coming from Los Angeles, I’ve witnessed the devastation firsthand, and I am committed to tackling this critical challenge. It requires all available tools, and science is crucial.”

Nevertheless, the future of FireSense may be uncertain due to ongoing concerns regarding funding for NASA and other federal programs.

While the budget cuts could impact project viability, the precise effects remain unclear. Signals indicate significant reductions to NASA’s Science Mission Bureau, which includes geoscience initiatives.

“Funding decisions have not yet been finalized,” stated Rachel Courley, a spokesperson for the White House Office of Management and Budget. NASA declined to comment and referred questions about the budget to OMB.

As the administration gears up to unveil its budget proposals shortly, concerns about possible cuts intensify.

“As a former NASA leader, I take pride in the agency’s comprehensive efforts to monitor and respond to wildfires,” remarked Sen. George Whiteside (D-Calif) in a statement. “Cutting essential wildfire programs like FireSense poses a risk to rebuilding communities like mine after devastating fires in Southern California.”

Stanford University’s Wara emphasized the far-reaching consequences of NASA’s wildfire research, noting that space agencies have significantly contributed to contemporary wildfire models and fire-related data.

“There’s no doubt that FireSense has considerably enhanced our understanding of fire behavior and risk,” he commented. “Losing this initiative would be detrimental, as regaining that knowledge is exceedingly challenging.”

New Study Challenges RFK Jr.’s Assertion of Rising Severe Autism Cases

This month, Health and Human Services Secretary Robert F. Kennedy Jr. shared the government’s latest findings on autism, presenting a stark and controversial viewpoint.

The notion that severe autism symptoms are on the rise lacks scientific backing. In fact, a recent study presented at the International Association for Research on Autism in Seattle indicates that the percentage of autism cases characterized by moderate to severe symptoms remained relatively stable from 2000 to 2016.

In recent weeks, Kennedy has consistently described autism as an “explosion,” attributing it to an increase in serious cases of intellectual disability.

“This trend is unprecedented. It raises alarms about community dynamics,” he told Fox News earlier this month. “This is effectively invalidating these children for their entire lives.”

Kennedy’s claims have drawn criticism from parents, advocates, and health professionals who argue that he represents a limited data set to generalize the autism spectrum.

According to a recent report by the Centers for Disease Control and Prevention, one in 31 children receives an autism diagnosis by age eight, though it did not distinguish between mild and severe cases.

During the briefing on April 16, Kennedy estimated that a quarter of diagnosed children were non-verbal or required assistance with toileting. A previous CDC study indicated that nearly 27% of individuals with autism are non-verbal or have an IQ below 50. Many researchers, however, suggest that the actual rates may be lower.

Autism is a spectrum disorder, meaning it encompasses a range of symptoms, from mild to more pronounced, influencing how individuals socialize, communicate, learn, and behave.

A new study released this week highlighted that only mild cases increased between 2000 and 2016.

This study analyzed data from the CDC’s Autism and Developmental Disorder Surveillance Network, tracking autism cases across the United States. The researchers assessed adaptive test scores (evaluating children’s social, communication, and daily living skills) in contrast to IQ scores that indicate intellectual disability to determine case severity.

Co-author Maureen Durkin, a professor of population health sciences at Wisconsin-Madison, stated:

David Mandel, a professor of psychiatry at the University of Pennsylvania, noted that he wasn’t involved in the analysis but remarked that adaptive scores were intended to capture severe cases like those described by Kennedy. Compared to IQ scores, adaptive scores better reflect how children with autism function in real life, including their ability to interact with others, manage self-care, and use the toilet independently.

The analysis indicated that in 2016, 1.2 out of every 1,000 children were diagnosed with moderate to severe autism, while mild cases surged by 139% in the same period, from 1.5 out of 1,000 in 2000.

“The rise is primarily among children without severe disabilities, and it would be beneficial for the current HHS secretary to be aware of that,” said Marianne Burton, a clinical professor of psychological science at the University of Connecticut.

The Department of Health and Human Services did not respond to requests for comment.

One potential reason for the increase in mild cases is improved identification by healthcare professionals. Developmental screening became increasingly common during the study period, and in 2006, the American Academy of Pediatrics began recommending universal autism screenings.

Additionally, the diagnostic criteria for autism were revised in 2013 to include mild cases, such as those previously classified as Asperger’s syndrome.

“We’re witnessing a significant expansion of diagnostic criteria that now encompasses individuals who wouldn’t have qualified for an autism diagnosis 50 years ago,” Mandel explained.

Dr. Alex Collebzon, clinical director of the Seaver Autism Center at Icahn School of Medicine at Mount Sinai, mentioned the analysis relied on health and educational records, potentially including children with mild symptoms who may not have undergone direct diagnostic assessments.

“Assessing this cohort, I believe they are likely quite confident in their diagnosis, but we are not observing an increase in prevalence,” he stated.

Kennedy rejects the notion that the rise is due to improved diagnostic practices, suggesting that only a “small fraction” of the increase in cases can be attributed to this.

“The media has perpetuated myths in this industry, promoting the idea that autism is more prevalent simply because we are identifying more cases,” he told Fox News host Sean Hannity this month.

Instead, Kennedy unfoundedly claims that environmental toxins are the primary drivers behind increasing cases and has tasked CDC scientists with identifying the source by September.

Kolevzon acknowledged that environmental factors could exacerbate underlying genetic risks for autism, but existing research has yet to pinpoint any specific causative agents.

“We are unlikely to uncover widespread environmental factors that would fully explain the rising prevalence,” he concluded.

Study Finds Younger Generations Are Less Happy Than Previous Ones

The happiness curve is unraveling.

For many years, studies have illustrated that people’s happiness over their lifetime typically follows a U-shaped trajectory. It tends to peak in youth, dip during middle age, and then increase again in older age.

However, recent surveys indicate that young adults today are experiencing less happiness than previous generations, signaling a flattening of this U-shaped curve.

This trend is further supported by a new research published in the journal Nature Mental Health. These initial findings stem from global prosperity research conducted in collaboration with researchers from Harvard and Baylor University.

Data collected by Gallup in 2023 revealed insights from over 200,000 respondents across 20 countries. On average, individuals aged 18 to 29 report challenges not only in happiness but also in physical and mental health, self-esteem, life meaning, relationships, and financial stability. The research combines these factors to assess whether participants achieve a state of prosperity.

The study found that participants reported generally low levels of prosperity until the age of 50, a trend observable in nations like the UK, Brazil, and Australia. Notably, the disparity between younger and older adults was most pronounced in the United States.

“It’s a rather bleak situation,” commented Tyler J. Vanderwielle, the lead author and director of Harvard’s Human Prosperity Program. These findings prompt critical reflections on whether we are sufficiently investing in the well-being of our youth.

Young adulthood has traditionally been viewed as a time of freedom and opportunities, yet research suggests this ideal may not align with the reality faced by many.

According to a 2023 report from the Harvard Graduate School of Education, young adults aged 18-25 in the U.S. reported double the levels of anxiety and depression compared to teenagers. Furthermore, perfectionism has surged among college students. Participation in community organizations, clubs, and religious organizations is declining, leading to increased loneliness among young people, reminiscent of trends seen in older populations.

“Post-study findings indicate that social connections are crucial for happiness, yet young people today spend less time with friends than they did a decade ago,” explained Laurie Santos, a Yale psychology professor and host of The Happiness Lab podcast. “Additionally, like individuals of all ages, young people are contending with a myriad of global issues, from climate change to economic and political divisiveness.”

The Greater Good Science Center at Berkeley recently announced Emiliana R. Simon Thomas as its science director. “We need to cultivate happiness without limiting ourselves.”

She believes the prosperity data reflects “the long-term impacts of prioritizing status and power” in the U.S., rather than our role in the broader community.

Dr. Vanderwielle emphasized the complexity of the research, which was conducted across varied economic, political, and cultural contexts. While the study’s geographical scope is broad, current analyses do not include mainland China due to delays in data collection. Moreover, low-income nations are underrepresented.

Not all countries show increased prosperity with age. In some places, such as Poland and Tanzania, prosperity has declined with age, while others, like Japan and Kenya, display a more conventional U-shaped pattern.

Nevertheless, in the majority of Western countries, and many others, young adults do not seem to be flourishing. Global Prosperity Research plans to continue data collection until 2027 to further elucidate these issues, according to Dr. Vanderwielle.

“We recognize that young people are in distress,” said David G. Blanchflower, an economics professor at Dartmouth who was not involved in the prosperity research; his research illustrates a similar trend.

Dr. Blanchflower has collaborated with the United Nations to facilitate discussions at Dartmouth, allowing experts to share insights on addressing these concerning trends.

Numerous theories exist regarding why young individuals are facing such troubles. He suggests that the problems may not solely arise from their constant engagement with screens.

“They’re not alone at home,” he remarked, invoking the dangers of social isolation, a theme explored in a seminal book by Robert D. Putnam published 25 years ago. “In fact, they’re not engaging socially at all.”
