A strain of avian influenza, known as H5N1 or highly pathogenic avian influenza, has sparked concerns in cattle herds across the United States in recent weeks. This development has raised significant alarm among health experts. The Chief Scientist at the World Health Organization (WHO) warned of the high mortality rate associated with the virus in humans.
As of now, the virus has affected more than 20 clusters in eight states of the U.S since a surge was initially reported last month.
The states that have been impacted so far include Idaho, Kansas, Michigan, New Mexico, North Carolina, Ohio, Texas, and South Dakota.
Moreover, on April 1st, the Centers for Disease Control and Prevention (CDC) confirmed that the virus had spread further in Texas and had infected individuals who were exposed to dairy cows.
Experts are emphasizing the need for extreme vigilance, investigation, and situational assessment due to the rapidly changing individual risk scenarios.
Infection of cattle is unprecedented.
This virus is not new – H5N1 was initially detected in 1996 in waterfowl in southern China. A new version of the H5N1 virus became widespread in 2021 and has continued to infect both wild and domestic bird populations globally.
Spread to other animals has occurred occasionally as the virus has crossed into various mammalian populations, including foxes, seals, sea lions, and humans, according to the CDC.
While the spread to mammals is a concern and can be fatal, past cases have shown that avian influenza typically stops spreading when it reaches mammalian populations, particularly humans.
However, in October 2022, a significant shift occurred when the virus spread from mink to mink at a mink farm in Spain, deviating from the usual transmission from birds to mammals. The USDA has confirmed that cows have been infected for the first time, and cow-to-cow transmission has contributed to the recent spread of avian influenza in dairy farms.
There is still uncertainty about how the disease spreads through cattle populations, with reports suggesting that the virus may be transmitted through milk due to high concentrations of the virus being shed in milk.
Is it safe to drink milk?
Most dairy products are pasteurized, which effectively eliminates the virus, making milk consumption safe for the majority of individuals. Drinking unpasteurized milk poses some risk, but experts suggest that even unpasteurized milk may be safe if not consumed immediately after milking.

The presence of the virus in milk raises questions about its transmission and impact on human health, as the virus is typically a respiratory disease.
How worried should I be?
The situation is under close monitoring by authorities, with several states implementing restrictions on dairy cow imports from affected regions. Scientists are analyzing virus sequences to identify genetic changes that could impact transmission and treatment effectiveness.
Concerns have been raised about the effectiveness of biosecurity measures on farms in controlling the spread of the virus. Experts emphasize the need for increased vigilance and monitoring to prevent further transmission.
Could H5N1 cause the next pandemic?
While there is uncertainty about the future, a widespread pandemic remains unlikely at this point. Authorities are prepared with stockpiles of vaccines and antiviral drugs effective against potential influenza strains.
There are two existing vaccine candidates against H5N1 available to manufacturers, along with several FDA-approved antiviral drugs. The focus remains on combating bird flu and preparing for any potential future outbreaks.
Experts continue to monitor the situation closely and emphasize the importance of staying informed and prepared for any developments.

Humanity has always dreamed of traveling beyond our solar system to the stars, but the vastness of the universe has kept us grounded. Our closest star, Proxima Centauri, is a staggering 4.24 light years away, which is too far for us to wait patiently.
Recently, on April 23, NASA launched the Advanced Composite Solar Sail System from New Zealand, a system that uses lightweight sails to propel spacecraft instead of traditional rockets. This development has excited both experts and science fiction fans, as it opens up possibilities for long-distance space travel.
How solar sail works
Instead of using thrusters and fuel like traditional spacecraft, solar sail systems use reflective sails to absorb momentum from photons emitted by the sun. This technology enables spacecraft to gain acceleration without the limitations of fuel. In space, where there is no air resistance, a slight push from the sun is all that’s needed for propulsion.
Solar sails operate similar to sailing ships, utilizing the momentum of photons for movement. By harnessing the sun’s energy, spacecraft can travel far distances at manageable speeds.
How fast can an interstellar probe travel with a solar sail?
The speed of a solar sail system depends on factors like the size of the sail, spacecraft mass, and distance from the sun. With creative maneuvers like slingshot maneuvers and potential laser boosts, spacecraft using solar sails can achieve speeds close to 20% of the speed of light.
Future solar sail systems could reach speeds up to 20 percent of the speed of light. – Image credit: NASA/Aero Animation/Ben Schweighart
Will humanity ever be able to sail to another planet?
Potentially, solar sail technology could pave the way for human interstellar travel in the future. However, there are challenges, such as sustaining long-term missions for generations and addressing relativistic effects caused by near-light speed travel.
What exactly is NASA's solar sail mission?
NASA’s Advanced Composite Solar Sail System is a demonstration of solar sail technology that aims to test a new lightweight boom made of flexible materials. The mission involves a CubeSat deploying an 80 square meter sail in orbit to gather data for future solar sail missions.

This annual event is the culmination of Sui's extraordinary debut
Last week, more than 1,000 projects, partners, investors and enthusiasts from 65 countries gathered in Paris for the celebration. Sui Proudly at Layer 1's 1st Global Sui Basecamp Conference.
At its first annual event held during Paris Blockchain Week, Sui was welcomed by developers and builders from around the world during the two-day event. Speakers at Sui She Basecamp spanned all aspects of the industry, from payments to gaming, e-commerce to Major League Sports, and provided commentary through keynotes, panel discussions, and fireside chats.
The event was punctuated by three important announcements. In partnership with Playtron, the Sui team announced:SuiPlay0x1 is the world's first lightweight handheld gaming device designed with native Web3 functionality, promising a new gaming experience. Additionally, First Digital Labs joins the announcement that FDUSD, the fastest growing stablecoin in cryptocurrencies, will become Sui's first native dollar-backed stablecoin, adding that it is already the fastest growing stablecoin in the industry. This will be a boon for the DeFi ecosystem. Finally, Sui announced Enoki, his Web3 utility suite that makes it very easy for businesses to leverage distributed solutions within their applications, products, and services.
Sui Basecamp participants from 65 countries had the opportunity to meet each other in person.
“In building Sui, we started with a blank canvas. We aimed to create a great platform for decentralized applications without the structural limitations found in other blockchains.” said Evan Cheng, co-founder and CEO of Mysten Labs, founder of Sui Network. . “Less than a year after we launched Sui's mainnet, the remarkable strength of Sui's performance has validated that approach, from near-unlimited horizontal scalability to industry-leading execution speed; Achieving the highest number of transactions in a single day of any blockchain to date, Sui's performance has been exceptional and the network has only scratched the surface.”
The industry veterans who founded Sai launched their mainnet nearly a year ago with high expectations, and the network has performed extremely well. Rather than replicating an existing network, the Sui team started from scratch to build an entirely new infrastructure layer that addresses the shortcomings of existing blockchains. They started by creating a new smart contract language, Move, and then created a new object-centric architecture that enables performance and functionality not available on existing blockchains. The result is the industry's only blockchain, a universal coordination layer for intelligent assets.
Sai is the industry leader in delivering ultra-fast transactions with recorded finality times of just 400ms. Similarly, Sui's scalability is also at the highest level, reaching 297,000 TPS in a controlled environment. However, the Sui team is constantly improving its technology. At the conference, members of the Sui team announced the next advancements in speed and scalability: Mysticeti, which significantly reduces the time to finalization of Sui, and Pilotfish, which enables nearly unlimited horizontal scaling for validators. .
And beyond its performance in test environments, Sui has broken records for transactions performed in a single day in just four months, higher than any existing blockchain while fees remain low and stable. Achieved. Remarkably, in almost his year on mainnet, Sui has not experienced a single minute of her downtime.
Gradually, after a series of community events around the world, Sui's early notable milestones, sustained ecosystem growth, and builders bypassed other blockchains to leverage the Sui network. A flurry of media articles highlighting the multiple stories of builders, developers, investors, and the broader community began to understand. The potential of Sui's groundbreaking blockchain technology. The crowd that gathered at Sui Basecamp 2024 represented the culmination of Sui's arrival.
“The overwhelming turnout and vibrant enthusiasm of our inaugural Sui Basecamp event reflects the Sui community, which is fascinated by Sui’s potential to improve people’s lives.” Sui Foundation Money said Greg Ciolounis, Managing Director. “Over the coming months, the Sui Foundation will benefit from the ecosystem of projects leveraging Sui and their applications to make Sui one of the most widely adopted blockchains to solve real-world challenges.” With state-of-the-art technology and web3's most dedicated and professional community behind it, Sui's progress to date will continue to grow this network. It gives you a glimpse of what you can accomplish.”

Using sensitive instruments aboard ESA’s International Gamma-ray Astrophysics Laboratory (Integral) mission, astronomers GRB231115A Taken from the center of Messier 82 (M82, NGC 3034, or the Cigar Galaxy). Messier 82 (M82, NGC 3034, or Cigar Galaxy) is a starburst irregular galaxy located 12 million light-years away in the constellation Ursa Major. They say the spectral and timing characteristics of GRB 231115A, as well as the lack of X-ray and optical observations and gravitational wave signals several hours after the event, indicate that this outburst was the result of a giant flare from a magnetar. Suggests. They conclude that starburst galaxies like Messier 82, which are known to produce magnetars, could be promising targets for studying giant flares.
On November 15, 2023, Integral detected a burst of gamma rays that lasted just one-tenth of a second. The detection was sent to the Integral Science Data Center, where software determined it came from the nearby galaxy Messier 82. A small square on Integral's map indicates the location of the burst. Blue circles on the two cropped images indicate corresponding locations. Image credit: ESA / Integral / XMM-Newton / INAF / TNG / M. Rigoselli, INAF.
Giant flares are short explosive events that release very large amounts of energy as gamma-ray bursts (GRBs).
Only three such flares have been observed from magnetars in our Milky Way galaxy and the nearby Large Magellanic Cloud in the past roughly 50 years.
Observations of giant flares from distant magnetars are hampered by the fact that at long distances it is difficult to identify the source of the energy burst.
“Some young neutron stars have very strong magnetic fields, more than 10,000 times stronger than a typical neutron star. These are called magnetars. They emit energy as flares, and sometimes these flares can be huge,” said ESA astronomer Dr. Ashley Climes.
“However, in the past 50 years of gamma-ray observations, huge flares from our galaxy's magnetars have only been observed three times.”
“These explosions are extremely powerful. The explosion detected in December 2004 came from 30,000 light-years away from us, but was still powerful enough to affect the upper layers of Earth's atmosphere. It's like a solar flare coming from much closer to us.
“The flare detected by Integral is the first confirmation of the existence of a magnetar outside the Milky Way,” said Dr. Sandro Meleghetti, an astronomer at the National Institute of Astrophysics.
“We suspect that some of the other 'short gamma-ray bursts' revealed by Integral and other satellites are also giant flares from magnetars.”
“This discovery will begin the search for other extragalactic magnetars. If we can find more stars, we will be able to understand how often these flares occur and how the stars lose energy in the process. We can begin to understand that,” Dr. Cromes said.
“However, such short-lived explosions can only be caught by chance if the observatory is already pointing in the right direction,” said Dr. Jan-Uwe Ness, a scientist at the Integral project.
“This makes Integral, with its wide field of view more than 3,000 times the area of the sky covered by the Moon, extremely important for these detections.”
“Messier 82 is a bright galaxy in which star formation occurs,” the authors said.
“In these regions, massive stars are born, live short, turbulent lives, and leave behind neutron stars.”
“The discovery of magnetars in this region confirms that magnetars are likely young neutron stars.”
“The search for additional magnetars will continue in other star-forming regions to understand these extraordinary objects.”

Recovering ancient records of the Earth's magnetic field is difficult because the magnetization of rocks is often reset by heating during burial due to tectonic movements over a long and complex geological history. Geoscientists from MIT and elsewhere have shown that rocks in West Greenland's Isua supercrustal zone have experienced three thermal events throughout their geological history. The first event was the most important, heating rocks to 550 degrees Celsius about 3.7 billion years ago. His two subsequent phenomena did not heat the region's northernmost rocks above 380 degrees Celsius. The authors use multiple lines of evidence to test this claim, including paleomagnetic field tests, metamorphic mineral assemblages across the region, and temperatures at which the radiometric ages of observed mineral assemblages are reset. They use this body of evidence to argue that an ancient record of Earth's magnetic field from 3.7 billion years ago may be preserved in the striated iron layer at the northernmost edge of the magnetic field. .

In a new study, Professor Claire Nicholls from the University of Oxford and colleagues examined a range of ancient iron-bearing rocks from Isua, Greenland.
Once locked in place during the crystallization process, iron particles effectively act as tiny magnets that can record both the strength and direction of a magnetic field.
Researchers found that 3.7 billion-year-old rocks exhibited magnetic field strengths of at least 15 microteslas, comparable to modern magnetic fields (30 microteslas).
These results provide the oldest estimates of the strength of Earth's magnetic field derived from whole rock samples, providing a more accurate and reliable estimate than previous studies using individual crystals.
“It's very difficult to extract reliable records from rocks this old, so it was really exciting to see the primary magnetic signals start to emerge when we analyzed these samples in the lab,” Professor Nichols said. said.
“This is a very important step forward in our efforts to understand the role of ancient magnetic fields in the creation of life on Earth.”
Although the strength of the magnetic field appears to remain relatively constant, the solar wind is known to have been significantly stronger in the past.
This suggests that surface protection from the solar wind may have strengthened over time, thereby allowing life to leave the protection of the oceans and migrate to the continents.
The Earth's magnetic field is created by the mixing of molten iron within a fluid outer core, driven by buoyancy as the inner core solidifies, forming a dynamo.
During the early stages of Earth's formation, a solid inner core had not yet formed, leaving unanswered questions about how the initial magnetic field was maintained.
These new results suggest that the mechanisms driving Earth's early dynamo were as efficient as the solidification processes that generate Earth's magnetic field today.
Understanding how the strength of Earth's magnetic field has changed over time is also key to determining when Earth's interior solid core began to form.
This helps us understand how fast heat is escaping from the Earth's deep interior, which is key to understanding processes such as plate tectonics.
A key challenge in reconstructing Earth's magnetic field back in time is that any event that heats rocks can change the preserved signal.
Rocks in the Earth's crust often have long and complex geological histories that erase information about previous magnetic fields.
However, the Isua supercrustal zone has a unique geology, sitting on a thick continental crust and protected from extensive tectonic movements and deformation.
This allowed scientists to build clear evidence for the existence of magnetic fields 3.7 billion years ago.
The results may also provide new insights into the role of magnetic fields in shaping the development of Earth's atmosphere as we know it, particularly regarding the release of gases into the atmosphere.
“In the future, we hope to expand our knowledge of Earth's magnetic field before oxygen increased in the Earth's atmosphere about 2.5 billion years ago by examining other ancient rock sequences in Canada, Australia, and South Africa. “We believe that this is the case,” the authors said.
“A better understanding of the strength and variability of ancient Earth's magnetic field will help determine whether the planet's magnetic field was important for harboring life on the planet's surface and its role in the evolution of the atmosphere. Masu.”

WASHINGTON – The Environmental Protection Agency issued a rule on Thursday that will require coal-fired power plants to capture smokestack emissions or shut down. This new regulation aims to limit greenhouse gas emissions from fossil fuel-fired power plants, which are a major contributor to global warming. It is part of President Joe Biden’s pledge to eliminate carbon pollution from the power sector by 2035 and the entire economy by 2050.
The rule includes measures to reduce toxic wastewater pollutants from coal-fired power plants and safely manage coal ash in unlined retention ponds. EPA Administrator Michael Regan stated that the rule will reduce pollution, protect communities, and improve public health while ensuring a reliable electricity supply for the nation.
Industry groups and Republican-leaning states are expected to challenge the rule, citing concerns about the reliability of the power grid. However, environmental groups have praised the EPA’s actions as crucial in combating climate change and protecting public health.
The rule sets standards for existing coal-fired power plants to control carbon emissions, with future plants required to capture up to 90% of their carbon pollution. Coal-fired power plants must reduce or capture 90% of their carbon emissions by 2032 to continue operating beyond 2039. Plants scheduled to be retired by 2039 will also face stricter standards.
The EPA rule does not mandate carbon capture and storage technology but sets a cap on carbon pollution that power plant operators must adhere to. The regulation also addresses toxic wastewater pollution from coal-fired power plants and the safe management of coal ash, a hazardous byproduct of coal combustion.
Overall, the EPA’s new rule represents a significant step in reducing carbon pollution, protecting public health, and moving towards a cleaner energy future for the United States.
“Get ready!” This immortal motto of the Scout movement will come to the mind of many readers who read the paper “Dynamics of bloodstain patterns in microgravity environment: Pilot study observations on the next frontier of forensic medicine.”
Reader Sarah Rosenbaum flagged feedback on the study’s first clearly stated purpose: “Investigating the ultimate violent criminal acts that occur outside of the global environment.”
This is the most futuristic forensic science. “It’s almost here.” The most effective approach is joint criminal investigation between the United Kingdom and the United States. The researchers are from Staffordshire University and Hull University in the UK, and the University of Louisville in Kentucky and Roswell Police in Georgia in the US.
“We hypothesize that the calculated impact angles would be more accurate if gravity were removed as a force acting on the blood droplet in flight,” they write.
They performed tests, or rather flew, aboard a parabolic flight research airplane that took off and landed at Fort Lauderdale-Hollywood International Airport. (Fort Lauderdale, like many cities in Florida, is no stranger to blood splatter. We see a steady increase in the number of violent crimes According to statistics reported by the local police department’s crime analysis department, it will occur between 2020 and 2023.)
In the experiment, “a 1 cc syringe containing a blood analogue was used to inject the liquid onto a flight path approximately 20 cm long, which was intercepted by a 16.5 cm x 16.5 cm target.” [made of] Fifty pound paper adhered to foam board backing.
The study found that droplets that hit paper at a 90-degree angle behaved as predicted by the traditional forensic blood droplet equation. But while this is a blood-stirring challenge for forensic scientists and true crime enthusiasts alike, someone needs to come up with a better equation for predicting what will happen from the other angle.
Thinking: Inside the box
Seeing sometimes leads to believing. Feeling, hearing, and reasoning are equally powerful when combined.
Shorey Croom, Hanbei Chow, and Chaz Firestone of Johns Hopkins University in Baltimore, Maryland, explain this in the magazine. PNAS How did they try to answer the question “?” “Can you tell what another person is trying to learn just by observing their movements?”
They filmed a volunteer shaking an opaque box and attempting to measure i) the number of objects hidden inside, or ii) the shape of the objects inside. He then asked others to watch the video and tried to determine “who is shaking because of the numbers and who is shaking because of the shapes.” Most observers were pretty good at recognizing who was shaking and why.
Back in 2017, Milte Plesier of Delft University in the Netherlands and Jeroen Smeets of Vrije Universiteit Amsterdam spoke to attendees of the IEEE World Haptics Conference in Fürstenfeldbruck, Germany, about a project they called “How many objects are in this box?”
Their method was simple. “We investigated how accurately participants could determine the number of wooden balls inside a box by shaking it.” They found that while they were able to perform the task accurately, they systematically underestimated the number of more spheres. The larger numbers they tested were 4 and 5. The situation with larger quantities remains theoretically unknown.
stick to fruit
Many scientists will not be able to determine whether the metal sticks to the fruit.
Generally speaking, if properly persuaded, they will. News about this can be found at “Reversibly attaching metals and graphite to hydrogels and tissues” by Wenhao Xu, Faraz Burni, and Srinivasa Raghavan of the University of Maryland.
writing in diary ACS Central Science “We have discovered that hard conductors (such as metals and graphite) can be bonded to soft aqueous materials (such as hydrogels, fruit, and animal tissue) without the use of adhesives.” The adhesion is caused by a low direct current electric field… [This] It can also be achieved underwater, where normal adhesives cannot be used.
“The experiment is very simple,” the study says, anticipating that many people would be surprised by such a simple, hitherto essentially unknown effect.
Accidental genital glow
Faraz Alam sent us the results of his research with colleagues at Imperial College London, published in the journal 2013. PLoS One “This is the paper on which I accidentally made my genitals glow in the dark.” The title is “Non-invasive monitoring of Streptococcus pyogenes vaccine efficacy using intravital optical imaging”. Those reproductive organs belonged to mice.
This spurred feedback that reminded me of a paper on humans published in 1950 by P. A. MacDonald and M. Sidney Margolese. Obstetrics and gynecology questionnaire. They called it “Luminous phenomenon of female external genitalia”.
These are both examples of how scientists perceive the wonders of biology.

Mouse brain hippocampus (red) containing some rat cells

Rat cells grown in the brains of mice without a sense of smell have enabled them to acquire the sense of smell. This is the first time that one species has experienced the world through the sensory neurons of another species.
When cells of one species multiply within the body of another species, the resulting organism is known as an interspecies chimera. These have previously been used to study specific tissues, such as mice containing cells of the human immune system, to study disease responses. However, creating chimeras of other tissues, such as neural tissue, is more complex.
Researchers at the University of Texas Southwestern Medical Center previously bred mice with parts of rat brains transplanted into them. Now, another team of researchers has shown that this cross-species chimerism may confer the ability to smell in mice genetically modified to lack scent-sensing neurons.
christine baldwin The researchers at Columbia University in New York injected these engineered mouse embryos with rat stem cells. Once the embryos became adult mice, the researchers monitored neuronal activity. The researchers discovered that these animals have functional neural pathways for sensing odors, made up of both rat and mouse cells that can communicate directly with each other.
When researchers tested these mice's sense of smell by searching for hidden mini Oreo cookies, they found that the mice that received stem cell injections found the food more easily, as opposed to the same genetically modified mice. It turned out that it was possible. It wasn't a chimera.
“This is a huge opportunity for human health, allowing us to better understand how to create cell replacement therapies for humans,” Baldwin said. “We can also create models in mice and rats for diseases that affect long-lived organisms.”
The fact that rat cells were able to facilitate food exploration in mice, which normally don't have a sense of smell, is very impressive, he says. walter lowe at the University of Minnesota. “Now, it is not yet clear whether something similar to this can occur in even different species, but at least [this study] Shows what's happening in two relatively close species [in evolutionary terms]” he says.

Meta’s stock price tumbled 15% on Wall Street Thursday in response to commitments to ramp up spending on artificial intelligence, resulting in approximately $190 billion being wiped off the market value of the Facebook and Instagram parent company.
During a conference call on Wednesday, Mark Zuckerberg, Meta’s CEO, emphasized the necessity of increasing spending on AI technology in order to generate “significant revenue” from the company’s new AI products. “There is a need for an increase,” he stated.
The stock price of Meta had previously benefited from stringent cost-cutting measures in 2023, which Zuckerberg referred to as “the year of efficiency.” However, investors were spooked when Meta raised the upper limit of its capital spending guidance from $37 billion to $40 billion on Wednesday.
Meta recently launched Llama 3, the latest iteration of its AI model and image generator, which can update images in real-time while users input prompts. This update also sees the expansion of Meta AI, the company’s AI-powered assistant, to more than 10 markets outside the US, including Australia, Canada, Singapore, Nigeria, and Pakistan. Chris Cox, Meta’s chief product officer, mentioned that the company is still working on implementing this in Europe.
The decline in stock price comes after Meta Inc. experienced a record increase in market value in February, adding $196 billion to its market capitalization following the announcement of its first dividend, which was, at the time, the largest single-day gain in Wall Street history. However, Nvidia, a prominent supplier of chips for AI models, later surpassed this record with a $277 billion profit.
UUntil recently, visitors to New York essentially had two options. A hotel room or a short-term rental platform like Airbnb. But in September 2023, the city began enforcing a 2022 law that prohibits people from renting a home for less than 30 days (unless the host stays in the home with a guest).
Currently, hotel rooms are the only legitimate option for people visiting the city, but they are out of reach for many. Most Times Square hotels don’t have rooms for less than $300 a night. Searches on Thursday, May 2nd found Muse for $356, Hampton Inn for $323, and Hard Rock for $459 (but due to dynamic pricing, these can change regularly). They become more expensive. Hotel prices rose at twice the rate of inflation from the first quarter of this year to the first quarter of 2023, said Jan Freitag, an analyst at real estate data firm Coster Group.
Many visitors and New Yorkers are turning to the underground rental market, where Facebook groups, Craigslist posts, Instagram listings, and reviews have become the go-to for finding short-term rentals in the five boroughs.
If you have friends in New York, you’ve probably seen their Instagram stories. “Hello everyone! I’m renting out my room in my 5-bed apartment to him again for 4 days over Easter! I have to deal with a dog and a rude roommate! DM me if you’re interested!”
Other travelers headed to New Jersey, making the kaleidoscopic city across the Hudson the nation’s fastest-growing Airbnb demand market, according to analytics site AirDNA. Other companies are snapping up hotels, which are expected to become even more expensiven the coming years. For many tourists, a good answer to the so-called Airbnb ban has not yet been found.
Yoya Busquets, 56, had been considering an Airbnb in New Jersey, but she really wants to stay there when she visits from Barcelona with her husband and two teenage daughters in early September. . She took a quick peek at her Facebook, where she chatted on Messenger with some people advertising short-term rentals. The last time she visited New York was in 2012, when she stayed at an Airbnb in Brooklyn, and she hopes to have a similar experience. She might get lucky.
“I’ve been in contact with a girl who has a room available for a week, and it’s listed on Airbnb as in New Jersey, but when I contacted her, she said it was in Brooklyn,” she said.
The apartment happened to be close to the area she had previously stayed in and was within her $160 per night budget. Considering the cost of a hotel and the space her daughters needed to relax after a busy day, it was the best option she found. But that setup is probably in violation of the new law, which is why the apartment is listed in Jersey.

AirDNA, which tracks data from short-term rental sites like Airbnb and Vrbo, says listings for stays of less than 30 days have declined by 83% since August 2023, when the regulations began taking effect. At one time in New York City he had 22,200 short-term properties available. That number currently stands at just 3,700, according to AirDNA.
Tesin Parra, 24, was looking for a job that would allow her to continue living in the United States after completing her thesis and classes, while also looking for a place for her family to stay as she graduates from New York University in May. Program for Journalism.
“This is their first time in New York City, so I want them to have a good experience,” Para, who is originally from India, said of her parents and grandmother. “She wanted to do an Airbnb so she could also cook,” she said.So she was disappointed when she learned that short-term rentals weren’t really an option anymore.
Parra wants a place with space for her family to gather. As a sign of her gratitude and respect, she wants to cover the cost of her family’s accommodation and has budgeted around $200 (£160) per night for a week-long stay.
“I’m kind of stuck as to what to do,” Parra said. “Probably a hotel, but I’d have to pay about $400 a night, and I don’t have that kind of money.”
Now, with the double stress of finishing school and facing hotel bills she can’t afford, she’s at a crossroads. She either chooses a hotel, has her parents pay for it, or rents something short-term, which is technically impossible in New York. Legal?
Without the accountability and protection that platforms like Airbnb offer, avoiding scams when searching for short-term rentals has become the norm. So Pala skipped scanning his Craigslist altogether. Currently, she is considering booking an Airbnb in New Jersey, but she worries that the local PATH train traffic will be an inconvenience for her grandmother.
This regulation was passed with the goal of keeping rent prices in check for New Yorkers by putting apartment inventory back on the market, but it is often important for New York renters and homeowners who lived in apartments while still living in apartments. It also cut off a major source of income. Where they were when they were out of town. Some New Yorkers are still looking for ways to bring in funds.
Kathleen, whose last name is withheld for privacy reasons, only recently began renting an East Village apartment on the underground rental market. The 29-year-old travels frequently for her personal finance job and to visit her family in North Carolina. According to her, she’s out of town for about four months a year, and of course, she still has to pay $2,600 a month in rent while she’s away. To make up for some of her lost money, she started connecting with undocumented people through Facebook groups.

“I thoroughly vetted a lot of people,” she said, voicing concerns about how her space would be treated given the lack of protection that short-term rental platforms offer hosts. I made it. She has two guests: her. One is a weekend visitor, the other stays at her apartment for three weeks in the summer. They pay her $50 a night.
“I always have a side hustle,” she said. “If I can make extra money, why not make extra money? I live in a great place. I thought it would be a nice, cute place.”
This is the spot where a visitor like Juan José Tejada could become a champion. Tejada, a wellness influencer from Bogotá, Colombia, is visiting New York for nine days in July with his best friend. He began his location search by looking at hotels, but he soon realized they were too expensive.
“I’m 25 years old. I’m traveling with my best friend. And, you know, we don’t have that much of a budget,” he said. At the suggestion of a cousin who lives in the city, Tejada used Facebook to search for short-term rental properties. What he discovered was four times his budget of $100 to $200 per night. But that wasn’t the only problem.
“When I was looking for short-term rental properties, the payment situation was a little tough,” Tejada said. Not in Colombia. “
Tejada and her friend ended up booking a hostel called Hi New York City on the Upper West Side, which cost about $55 a night for a bunk room with a shared bathroom. was. Tejada said she considered Airbnb, which has an on-site host, but couldn’t find a suitable option. It’s not the apartment he dreamed of breezed in and out of as if he were a local, but it’s good enough.
People are coming up with their own solutions for short stays. On Instagram, there are accounts like Book That Sublet NYC, where over 4,000 followers tune in to frequently posted daily and weekly sublets, as well as endless “sublets.”Book my apartment!“, or an apartment exchange callout shared on Instagram Stories. And there are long-standing apartment exchange sites like HomeExchange and HomeLink that offer visitors another way to get their foot in the door of a city apartment.
Supporters of the new regulations thought that limiting short-term rentals would bring long-term rentals back onto the market and perhaps help lower rents in the notoriously expensive city. Jamie Lane, chief economist at AirDNA, said after nearly seven months, there was still no widespread impact.
Jonathan Miller, CEO of appraisal firm Miller Samuel, said that although a small number of apartments have returned to the rental market since the law was changed, mortgage rates remain high and mortgage rates are declining. He explained that this is because it has been gradually increasing since its inception. In 2017, prospective buyers refrained from making purchases for the time being, and rents rose.
Parra, a New York University student, doesn’t think the regulations are the most effective way to address New York’s housing crisis. “I don’t understand how this regulation makes sense. Not in terms of relieving the burden of the number of Airbnbs, but considering that New York City is an immigrant city. ‘Is it fair?’ she said.
But Busquets, who will be visiting in September, has seen firsthand the impact of tourism and short-term rentals on the world-renowned destination.
“I come from a city where the Airbnb craziness is actually displacing local residents and people who have lived there for years,” she said. “The owners wanted to keep people who were there just for short-term rentals because it was more profitable.”
Busquets said Airbnb made Barcelona uninhabitable and she eventually left for the suburbs herself. She added: “It’s changed. It’s not the same city it was 10, 15 years ago.”
TikTok’s service, offering perks like gift certificates for video watching, was ceased by the company after the European Union threatened to block it due to concerns of child addiction.
Digital Commissioner Thierry Breton stated that TikTok Lite’s features in France and Spain comply with obligations under the Digital Services Act (DSA). “I couldn’t prove it, he said under the law,” he mentioned.
The EU believes the service could be as addictive as cigarettes and has given TikTok 48 hours to respond with new defenses.
As a precautionary measure, TikTok sent a letter to Breton informing the suspension of its services.
Breton emphasized, “Our children are not social media guinea pigs. The DSA ensures safety in the EU’s online spaces.”
This is the first instance of the EU taking legal action since the DSA came into effect in August last year.
Following the US Senate’s legislation, TikTok faces further challenges either in banning it or compelling the sale of its US operations.
Breton expressed disappointment in the company’s decision to proceed with the service despite prior concerns raised by the European Commission regarding child protection issues linked to TikTok.
“We welcome TikTok’s move to suspend the ‘rewards program’ in TikTok Lite on April 22nd, taking into account the ongoing case and willingness to implement interim measures,” he remarked.
The litigation against TikTok concerning addictive risks continues, including an assessment of the compliance of TikTok Lite launch with the DSA.
Effective Wednesday, TikTok, owned by ByteDance, will suspend its Tasks & Rewards program in France and Spain for new users for 60 days.
It will also cease services for existing subscribers by May 1 at the latest, and halt the rollout in other EU nations.
This suspension marks the first time the EU has exercised its authority under the DSA to enforce compliance with EU laws on social media companies, including X and Facebook, risking global ban or up to 6% sanctions income.
A European Commission spokesperson confirmed two ongoing formal proceedings against TikTok, including this case concerning TikTok Lite.
The initial lawsuit filed in February addressed child protection on TikTok, covering age verification, advertising transparency, and addressing addictive designs and harmful content risks.
A TikTok spokesperson mentioned, “TikTok always strives to engage constructively with the EU Commission and regulatory authorities.
“Hence, we are voluntarily suspending the rewards feature on TikTok Lite and addressing the raised concerns.”
The House of Representatives passed a bill requiring TikTok owner ByteDance to sell the platform or risk a complete ban in the US. The Senate quickly followed suit, and the bill was signed by Joe Biden the next day.
This move poses a significant threat to TikTok in the US, especially since a previous ban in Montana was ruled unconstitutional and never enforced.
Here’s what you need to know about the bill, the possibility of a TikTok ban, and its implications for the platform’s 170 million US users.
Is the US really trying to ban TikTok and why?
The bill passed by the House is part of an ongoing political battle over TikTok, a platform that has seen massive growth since its launch in 2017. Lawmakers are concerned about data privacy and censorship issues related to TikTok’s Chinese parent company.
Despite TikTok’s assurances about data storage and access, lawmakers remain skeptical, leading to the recent legislation.
Various attempts to regulate TikTok in the US have been made, culminating in the recent bill passing in the House.
Does this bill really ban TikTok?
Under the bill, ByteDance must divest from TikTok within 165 days to avoid a ban. App stores could face penalties for hosting TikTok if the divestiture does not occur.
Supporters argue the bill offers ByteDance an opportunity to avoid a ban by selling TikTok to non-Chinese companies.
TikTok disputes this, claiming uncertainty about the sale’s approval and completion within the specified timeframe.
How did we get here?
Past bans and restrictions on TikTok, including efforts by former President Trump, have laid the groundwork for the current situation. Montana and other states have previously attempted bans, but legal challenges have prevented enforcement.
Recent demands from the Treasury Department raised concerns, leading to the development of the current bill.
How will the TikTok ban be enforced?
Enforcing a ban on TikTok faces technical and legal challenges due to the decentralized nature of the internet. Methods like blocking IP addresses could be circumvented using VPNs.
To fully restrict TikTok, the US would need to adopt stringent internet restrictions used by countries like China.
Who supports a possible TikTok ban?
Most Republicans and the Biden administration back the bill, with President Trump’s stance evolving over time. Efforts to ban TikTok have garnered bipartisan support.
Despite some opposition, the bill’s supporters believe it is crucial for national security and data privacy concerns.
Who opposes the TikTok bill?
TikTok vehemently opposes the bill and urges the Senate to reject it. Some lawmakers and civil rights groups argue the bill threatens free speech rights and could set a dangerous precedent.
Opponents of the bill emphasize the need for comprehensive social media regulation rather than targeting specific platforms like TikTok.
What will happen to TikTok in the future?
The bill still faces hurdles in the Senate, and its enforcement could be complex. TikTok’s lobbying efforts and legal challenges could impact the bill’s implementation.
Even if passed, legal challenges may arise, similar to previous bans that were blocked on constitutional grounds.

Hannah Verdier We’ve curated the 5 best podcasts hosted by pop stars, from Tim Burgess’ listening party to Sam Smith’s poignant exploration of HIV history.
ILast March, two men in tracksuits, hockey masks and matching laundry bags headed to the British Museum. Just outside, police on patrol asked two strange-looking men where they were going. “We’re going to the British Museum to loot the stolen goods,” one of them said. “See you there then!” replied the policewoman.
However, no arrests were made as nothing incriminating occurred. What actually happened was that one of the British Museum’s most famous objects, an artifact that, according to Egyptologist Monica Hanna, is a “symbol of Western cultural power” and “a symbol of British imperialism,” Rosetta’s “digital It was a robbery. stone.
The robbers, along with Hanna, who they had invited with them, went to the exhibit room where the stone monument was displayed and created a detailed 3D scan of it on an iPad. This effectively provided “looters” with a completely legal digital copy of the 196 BC artifact. But their goal is not just to digitize the Rosetta Stone, but to use location-based augmented reality technology (or geo-AR) to locate the Rosetta Stone in its place of origin, Rashid (or Rosetta) in Egypt. The idea was to return the images to local people and make them available for viewing. Send objects from your smartphone.
The two men behind the masks were Chidi Nwaubani and Ahmed Abokor, London-based product designers and creative consultants, respectively. Together they are booty, a radical “artist” collective and technology company founded in 2021, whose purpose is to “loot” cultural artifacts stolen from museums. First, we 3D scan them and then share them as enhanced digital artwork through non-fungible tokens (NFTs).
Because NFTs provide public proof of ownership of digital files, Looty’s method of “stealing” and redistributing works of art is connected to the lack of transparency often associated with institutions founded in colonial times. The aim is to challenge the fading of. The British Museum was embroiled in a scandal in August last year, when it was revealed that around 2,000 artefacts were stolen due to poor record-keeping, and that around half of its collection of around 8 million items had not been fully catalogued. However, the museum, which was founded in the 18th century, is once again facing scandal. public calculation.
“They’re less interested in the artifact and more concerned with the fact that they have it,” Abokor said. “Once again, it’s all about power.”
From organizing one of the main things interactive exhibit From its exhibition at the Venice Architecture Biennale last year to its installation at NFT Paris this February, Looty is taking the world of art and technology by storm. In November, they special projects department 1-54 Contemporary African Art Fair. Continuing his Rosetta Stone heist project, Abokor had created a replica of the Rosetta Stone wrapped in cloth and rope. Visitors can scan the stone using the QR code included in the piece’s description, which activates an animation on their mobile phone for an augmented reality (AR) experience that shows Rosetta’s Stone in its true size and glory. became.
Nwaubani and Abokor’s partnership dates back nearly 20 years, when they met at university in London and bonded over a shared creative spirit and African heritage. Nwaubani grew up mainly around Guildford and developed her interest in technology early by “coding her games on computers with floppy discs”. However, she experienced severe racism at school and her father, a university professor from Nigeria, forced her to change schools.
The night sky is a treasure trove of celestial wonders, and sometimes incredible events happen when no one is watching. Astronomers were thrilled when a satellite captured a rare explosion in space by chance, pointing in the right direction at the right time.
A massive eruption illuminated the galaxy known as M82, which is situated 12 million light-years away from Earth. Initially thought to be caused by a collision between two neutron stars, astronomers discovered that the explosion was actually the result of a superpowerful neutron star emitting an intense gamma-ray burst.
Neutron stars are the remnants of massive stars that exploded as supernovae, forming compact spheres with strong magnetic fields instead of collapsing into black holes.
The observed neutron star was identified as a magnetar due to its extremely powerful magnetic field, more than 10,000 times stronger than a typical neutron star. Magnetars are known to have the strongest magnetic fields in the universe and release energy through massive flares.
In November 2023, ESA’s INTEGRAL satellite accidentally detected an extragalactic flare which lasted only 10 seconds, triggering a gamma-ray burst alert that quickly reached astronomers worldwide.
Dr. Sandro Meleghetti, the lead author of the study published in the journal Nature, emphasized the significance of the burst coming from a nearby bright galaxy, and the subsequent observations failed to detect any visible light, X-ray, or gravitational wave signals.
This event confirmed the first magnetar flare outside the Milky Way, shedding light on the mysterious phenomena associated with these incredibly magnetic neutron stars.
Only three giant flares from galactic magnetars have been confirmed by scientists in the past 50 years, with the 2004 event being so powerful that it impacted Earth’s upper atmosphere akin to solar flares.
America is often described as the land of the free and the home of the brave. However, some parts of the country grapple with issues surrounding violent crime.
According to data from the FBI, dangerous cities are ranked based on the number of serious felonies reported per 100,000 people in a year. These felonies include murder, manslaughter, assault, and robbery.
Recent data indicates a general decline in violent crime across the United States. Technological advancements, such as real-time crime maps and gun detection software, are being utilized to enhance safety in urban areas. However, here are some of America’s most dangerous cities.

Cocoa swollen bud virus disease It is one of the most economically damaging cocoa tree diseases, accounting for almost 15-50% of crop losses in Ghana. This virus is transmitted when several species of mealybugs feed on cocoa plants.

Cocoa swollen shoot virus disease (CSSVD) first observed Infected by farmers in the eastern region of Ghana in 1936, the nature of the virus was identified in 1939.
CSSVD is considered the most economically damaging cocoa virus disease and can cause yield losses of 15-50% when severe strains are involved in infection.
Cocoa swollen shoot virus (CSSV) is classified as a member of the plant-infecting pararetroviruses of the genus Cocoa swollen shoot virus. badnavirus It contains nonenveloped rod-like particles that encapsulate a circular double-stranded DNA genome.
Previously, isolates and strains were grouped according to severity of symptom onset and geographic origin.
CSSVD is currently known to be caused by the following causes: complex of badnavirus seed Based on molecular structure.
CSSV affects all parts of the cocoa plant. Symptoms seen on leaves include red vein stripes on immature “flush” leaves, green-green vein spots or stripes that can occur in angular spots, removal of green-green veins, and various shapes Includes mosaic symptoms.
The virus causes swelling of the stem (nodes, internodes, tips) and roots.
In some strains, the infected pods change shape, becoming rounder and smaller and with a smoother surface.
“This virus is a real threat to the world's chocolate supply,” said Professor Benito Chen Charpentier, a researcher at the University of Texas at Arlington.
“Pesticides are ineffective against mealybugs, so farmers try to prevent the spread of the disease by cutting down infected trees or breeding resistant trees. However, Ghana has lost more than 254 million cocoa trees in recent years.
Farmers can combat mealybugs by vaccinating trees with CSSV. But vaccines are expensive, especially for low-wage farmers, and vaccinated trees produce less cocoa, making the damage caused by the virus even worse.

Professor Chen Charpentier and colleagues have developed a new strategy. Use mathematical data to determine how far apart farmers can plant vaccinated trees to prevent mealybugs from jumping from one tree to another and spreading the virus That's what it is.
“Mealybugs have several ways of getting around, including moving from canopy to canopy, being carried by ants, and being blown by the wind,” Professor Chen Charpentier said.
“What we needed to do was create a model for cocoa farmers to vaccinate unvaccinated trees to prevent the spread of the virus while making costs more manageable for smallholders. The goal was to be able to know how far away a tree could be safely planted.”
By experimenting with mathematical patterning techniques, the authors create two different types of models that allow farmers to create a protective layer of vaccinated cocoa trees around unvaccinated trees. Did.
“Although still experimental, these models are exciting because they can help farmers protect their crops while achieving better yields,” said Professor Chen Charpentier.
“It’s good for farmers’ bottom lines and it’s good for the world’s chocolate addiction.”

Messier 76also known as M76, NGC 650/651, or the Little Dumbbell Nebula, is a planetary nebula located approximately 3,400 light-years away in the northern constellation of Perseus.
This Hubble image shows Messier 76, a planetary nebula about 3,400 light-years away in the constellation Perseus. Image credit: NASA/ESA/STScI.
Since its launch in 1990, the NASA/ESA Hubble Space Telescope has made 1.6 million observations of more than 53,000 celestial objects.
To date, the Space Telescope Science Institute's Mikulski Space Telescope Archive contains 184 terabytes of processed data.
Since 1990, 44,000 scientific papers have been published from Hubble observations.
Hubble is the most scientifically productive space astrophysics mission in NASA history.
Demand for the use of Hubble is so high that it is currently oversubscribed by a factor of 6 to 1.
Most of Hubble's discoveries, such as supermassive black holes, exoplanet atmospheres, gravitational lensing by dark matter, the presence of dark energy, and the abundance of interstellar planet formation, were not anticipated before launch.
To commemorate the 34th anniversary of Hubble's launch, astronomers took a snapshot of the planetary nebula Messier 76.
“Messier 76 is located approximately 3,400 light-years away in the northern constellation of Perseus,” Hubble astronomers said.
“It is classified as a planetary nebula, an expanding shell of glowing gas ejected from a dying red giant star. The star will eventually collapse into a super-dense, hot white dwarf.”
“Although planetary nebulae are not related to planets, they got their name because astronomers in the 1700s using low-power telescopes thought these types of objects resembled planets.”
“Messier 76 consists of a ring that is visible head-on as a central bar structure and two lobes located at openings on either side of the ring. Before burning out, the star ejected a ring of gas and dust. ”
“This ring was probably formed by the influence of a star that once had a binary companion.”
“This sloughed off material formed a thick disk of dust and gas along the orbital plane of the companion star.”
“The hypothetical companion star is not seen in the Hubble image, so it may have been later swallowed by the central star.”
“The host star has collapsed to form a white dwarf,” the researchers said.
“It is one of the hottest stellar remnants known, at a scorching 139,000 degrees Celsius (250,000 degrees Fahrenheit), 24 times the surface temperature of the Sun.”
“The blazing white dwarf is visible pinpointed in the center of the nebula. The stars visible projected beneath it are not part of the nebula.”
“Sandwiched by the disk, two clumps of hot gas escape from above and below the 'belt' along the star's axis of rotation perpendicular to the disk.”
“They are propelled by hurricane-like outflows of material from dying stars, tearing apart space at 2 million miles per hour.”
“That's fast enough to travel from Earth to the Moon in just over seven minutes.”
“This intense stellar wind is channeling cooler, slower-moving gas that was ejected during the star's early stages of life, when it was a red giant.”
“Intense ultraviolet radiation from superhot stars makes the gas glow. The red color is due to nitrogen, and the blue color is due to oxygen.”
“Given that our solar system is 4.6 billion years old, according to cosmological timekeeping, the entire nebula is a fleeting event. It will disappear in about 15,000 years.”
An extinct species of giant salmon called Oncorhynchus lastrosus They boasted a pair of front teeth that protruded like fangs from the sides of their mouths, according to new research.

Oncorhynchus lastrosus It lived along the Pacific coast of North America (California, Oregon, and Washington) about 11 million to 5 million years ago.
This extinct species was first described in the 1970s from fossils discovered in the freshwater Gateway locality of the Madras Formation near the town of Gateway, Jefferson County, Oregon.
The fish was 2.4 to 2.7 meters (7.9 to 8.9 feet) long and weighed, by some estimates, close to 177 kilograms (400 pounds), making it the largest known member of its family. Salmonidae To live forever.
This species migrated from the Pacific Ocean to inland rivers to spawn, much like salmon today. And it was placophagous based on its numerous gill rakes and few small teeth.
but Oncorhynchus lastrosus It had two upper teeth, 2–3 cm (0.8–1.2 in) long.
Initially, paleontologists thought that these oversized teeth were oriented backwards in the mouth, like fangs, mainly because the tooth fossils were found separated from the rest of the skull. was. This led to the common name “saber-toothed tiger.”
However, through new CT scans and various analyses, Oncorhynchus lastrosus Using fossils collected over the years, Professor Kellyn Cresson of the Philadelphia College of Osteopathic Medicine and her colleagues were able to confirm that the fish's teeth did indeed point sideways out of its mouth, like a warthog.
“As a result, this species should be renamed 'spine-toothed salmon,'” the paleontologists said.
“It is unclear exactly what these teeth were used for, but it is likely that they were used for fighting other spiny-toothed salmon, for defense against natural predators, or as tools for digging nests. ”
“It is also possible that the teeth were used for multiple purposes,” the researchers added.
“However, the teeth were probably not used to capture prey. Oncorhynchus lastrosus It is believed that it was a filter feeder that fed on plankton. ”
“We've known for decades that these extinct salmon in Central Oregon were the largest of all time. Discoveries like ours mean they're probably more than just gentle giants. It shows that there was no such thing,” Professor Cresson said.
“The giant spines on the tips of their snouts would have helped them protect themselves from predators, compete with other salmon, and eventually build nests to incubate their eggs.”
“We are pleased to be able to give a new face to the giant spiny salmon and bring knowledge from the Oregon field to the world,” said University of Oregon researcher and director Dr. Edward Davis. Condon Collection, University of Oregon Museum of Natural and Cultural History.
“We also emphasize that females and males alike had huge fang-like teeth. So both sexes were equally terrifying,” said Professor Brian Sidlauskas, curator of fishes at Oregon State University. said.

In 1980, Disney World in Orlando, Florida, began developing a new method of generating electricity for its theme parks that would reduce the use of increasingly expensive oil. The solid waste-to-energy conversion plant took garbage, including plastics, and converted it into flammable gas using a method called pyrolysis. It opened in 1982 but closed a year later due to high operating costs.
Today, environmentalists cite the Disney story that shatters the reputation of a series of new technologies collectively known as advanced recycling, which takes plastic waste and turns it back into brand new plastic.
Their argument is dishonest. The failure of the Disney plant had more to do with the subsequent drop in oil prices than with any technical or environmental issues. Pyrolysis has improved significantly since the 1980s. In any case, Disney’s factory is designed to produce fuel, not classified as advanced recycling.
Advanced recycling is rapidly innovating with the potential to help solve the global plastics crisis, as reported in our feature “A surprising new technology that could recycle all plastics forever.” It has the potential to capture millions of tonnes of waste plastic and turn it back into a clean, fresh state by breaking it down into its molecular components. The goal is a circular economy that eliminates the need to make “virgin” plastic from oil.
It’s not a panacea. These factories produce toxic waste, have problems with their energy use, and perpetuate traditional plastics ahead of newer, greener alternatives. Campaigners are right to argue that it would be better to do away with plastic altogether. However, given practical considerations, they are not going away anytime soon, and most advanced recycling technologies are better for the environment than their alternatives.
There should be serious discussion about advanced recycling, especially whether it should be incorporated into future global treaties on plastic pollution. Make sure it’s based on fact and not a Disney story.
A diver injects vinegar into crown-of-thorns starfish as part of a culling program.
CSIRO
A culling program has successfully protected key areas of the Great Barrier Reef from voracious coral-eating starfish. Scientists who analyzed the results say efforts need to be scaled up to further protect coral reefs.
Crown-of-thorns starfish (COTS) are persistent predators of almost all types of coral within Australia’s Great Barrier Reef. Each starfish reaches a diameter of 1 meter and eats 10 square meters of coral reef each year.
Starfish live on coral reefs, and it is believed that increased nutrient input into reef waters due to agriculture and other human factors is increasing their numbers and exacerbating coral destruction. Between 1985 and 2012, they accounted for 40 percent of coral losses in the region.
When starfish erupted across the reef from 2012 to 2022, the Great Barrier Reef Marine Park Authority conducted a massive culling program. A team of divers injects the starfish with a single shot of vinegar or cow bile, which kills the starfish and prevents it from releasing its larvae.
Roger Beeden The Park Service and colleagues found that in areas where timely removals were carried out, outbreaks were limited and coral cover recovered and increased by up to 44%. Where no culling occurred, coral losses were severe. The study also confirmed that by preventing outbreaks on strategically important coral reefs, the larvae do not spread to other reefs on ocean currents, reducing further outbreaks.
To date, the program has focused on 500 of the marine park’s 3,000 reefs scattered throughout the park, which have significant value to the tourism industry or are home to starfish. were chosen because they are known to be important for the spread of
“The results we found in this study are the result of using integrated pest management. [the starfish] Just like managing plague locusts and other pest species, it needs to be done at the right time and on the right reef,” says Beeden.
But researchers recommend expanding the program from the current fleet of five to seven ships to 10 to 15 ships. “At any given time, about a third to a half of his 500 cases are involved in the current outbreak,” Beeden said.
Terry Hughes Researchers at James Cook University in Townsville do not agree that culling programs are worthwhile. “It is becoming increasingly clear that attempts to protect Great Barrier Reef corals by culling crown-of-thorns starfish on a few reefs are just a drop in the ocean,” he says.
Mr Hughes said geographical differences in starfish numbers and coral abundance – which the study attributed to levels of culling in different parts of the Great Barrier Reef – could be explained by which areas had suffered from recent cyclones and coral mass destruction. Events they say could be explained by who is most affected by large-scale bleaching. Professor Beeden acknowledges that it is difficult to separate these factors from the effects of selection, but he says: “Our results are strengthened and are not confounded by the fact that the increase in coral cover in the Townsville region was achieved despite two large-scale bleaching events in 2020 and 2022. do not have” “
Instead, Hughes says the priority should be to tackle global warming, which is accelerating the frequency and intensity of coral bleaching. “Each time there is a bleaching event, the Australian government announces additional funding to eliminate starfish from some coral reefs, shifting the focus away from addressing the causes of these outbreaks and reducing Australia’s greenhouse gas emissions.” he says.
Triangular gold flakes can be manipulated using mysterious quantum forces
George Zograf
A tiny gold device for controlling light is built using strange quantum effects hidden in seemingly empty space.
In 1948, physicist Hendrik Casimir theorized that when objects are brought close together in space, some objects experience a very weak gravitational pull due to imperceptible flickering of quantum fields in the gaps between them. Ta. Researchers then confirmed this Casimir effect in the laboratory. Betul Kyucukoz and his colleagues at Sweden’s Chalmers University of Technology have found a way to make this useful.
They wanted to build a cavity that would trap the light using two pieces of gold placed parallel to each other, so that the light would bounce back and forth between them and would not be able to escape. First, we created the bottom edge of the cavity by transferring triangular gold flakes ranging in size from 4 to 10 microns onto a small piece of glass. The top end of the cavity also contained a triangular gold flake, but instead of holding it in place with an instrument, the researchers attached it to the glass in a salt water solution containing an additional triangular gold flake. The gold flakes were then dipped in and then allowed to develop. Instead, work naturally.
One of those forces was the electrostatic force caused by the charge associated with the dissolved salt. Another is the Casimir effect. Kyuchkoz said he observed the experiment under the microscope many times and could always see the Casimir effect in action. This causes the floating gold flakes to move towards the gold flake where one is imprinted on the glass, and then he moves over the imprinted gold flake until the triangular footprints of the two flakes match. It was rotated.
This completes the assembly of a cavity that can trap light. The researchers were able to significantly control the cavity formation process, Kyucukoz said. For example, by using different concentrations of salt, we can adjust the strength of the electrostatic force so that the distance between the flakes is different for each cavity, creating cavities with slightly different dimensions of 100-200 nanometers. It can trap colored light.
Raul Esquivel Sirbento The professor at the National Autonomous University of Mexico said the idea of self-assembly, likened to throwing a Lego set into a pot and a structure emerges without having to manually press the pieces together, is not new. But he said his team’s experiment was more detailed and controlled than previous attempts to exploit the Casimir effect for similar purposes. But the Casimir effect can be very subtle, so there may be other effects here as well that haven’t been detected yet, Esquivel Servent said.
In the future, Küçüköz and his colleagues hope to use the cavity as part of more complex experiments with light, such as placing objects inside the cavity between two gold flakes.
The SLIM lander continues to take photos of the moon's surface.
JAXA
Somehow, Japan's Smart Lunar Survey Lander (SLIM) survived three lunar nights. This is an amazing feat. The moon's nights are so cold that the spacecraft's batteries and electronics fail, so a lunar lander can typically survive one day on the moon, or about two weeks on Earth.
The lunar lander is built to withstand the moon's nighttime temperatures, which can drop to -133°C (-208°F). SLIM is no exception. There are no heaters or special insulation designed to keep the spacecraft's electronics warm.
The original plan was for the lunar night to mark the end of the lander's mission, so no one expected to wake up again when night fell less than two weeks after SLIM's January 19 landing. I wasn't expecting it. But on February 25, the sun rose over SLIM's resting place near the moon's south pole, lighting it up again.
Alarmed, the SLIM operations crew on Earth began instructing the lander to image and measure its surroundings until the next lunar night, when the mission would truly end. In late March, the sun rose again and the lander powered on and began transmitting data to Earth.
By all standards, the mission was a shocking success, even after a difficult landing left the spacecraft tilted. But yet another surprise awaited – three nights later on April 23, SLIM was revived again.
X's SLIM official account Posted“SLIM maintained its primary functionality even after a three-night stay, which was not envisioned at the time of its design.” New photos of the lunar surface accompanying that post show that the lander once again understands the moon. It also shows that they are working hard to collect data that will not only help them do this, but also help them create a spacecraft that can withstand moonlit nights.
Fusion reactions have overcome two important barriers to operating in the “sweet spot” needed for optimal power production: increasing plasma density and keeping a denser plasma confined. This milestone marks another stepping stone toward fusion power, although commercial reactors are likely still years away.
One of the main avenues being considered in efforts to achieve fusion power generation is the use of tokamak reactors. These have donut-shaped chambers in which plasma, hotter than the surface of the sun, is trapped by giant magnets.
It was thought that there was a point known as the Greenwald limit, beyond which the plasma could not become denser without escaping the influence of the magnets, potentially damaging the reactor. However, experiments have shown that the power of a tokamak reactor increases proportionally to the square of the fuel density, so increasing the density is important to increase the power.
now, Siye Din General Atomics in San Diego, California, and colleagues have shown that there is a way to increase plasma density and have shown that plasma density can be stabilized. DIII-D National Fusion Facility The tokamak reactor was operated for 2.2 seconds at an average density 20 percent above the Greenwald limit. This barrier has been crossed before with low stability and short duration, but this experiment was importantly also performed with a metric greater than 1, known as H98(y,2).
H98(y,2) states that it is a complex combination of measurements and values that indicate how well the plasma is confined in the magnet. gianluca sarri At Queen's University Belfast, a value of 1.0 or higher indicates normal plasma retention.
“He's starting to show some sort of stable behavior where he can consistently be in the sweet spot,” Sarri says. “This was done on a small machine. If we extrapolate these results to a larger machine…we would expect to find a situation where we can achieve gains and significant power production over a significant period of time.”
Sarri said the DIII-D experiment relied on a combination of approaches that are not new in themselves, but that their combination appears to have produced a promising approach. The researchers increased the power by increasing the density in the center of the donut-shaped plasma, while allowing the plasma to sink at the end closest to the containment vessel, avoid plasma leakage. They also injected deuterium gas into the plasma to calm the reaction in certain areas.
DIII-D's plasma chamber has an outer radius of just 1.6 meters, but it remains to be seen whether the same method will work for ITER, the next generation tokamak being built in France. ITER has a radius of 6.2 meters and is expected to be completed. It is planned to generate plasma by 2025 at the earliest.
“These plasmas are very complex,” Sarri says. “Small changes in circumstances lead to large changes in behavior. Experimentally, it was a trial-and-error kind of approach, trying out many different configurations and basically seeing which one worked best. It was all about It's about forcing the plasma to do something that is completely against its nature and that it doesn't actually want to do.”
Ding says the experiment bodes well for the future of fusion power generation. “Many reactor designs require high confinement and high density at the same time. Experimentally, this is the first time this has been achieved,” he says. “Next steps will be costly and research is currently moving in many directions. We hope this document will help focus efforts around the world.”
Sarri says this work is another step toward a practical fusion power plant, but no one should expect a commercial reactor to be completed within the next five or even 10 years.

Botanists have used genome data from more than 9,500 species to map evolutionary relationships among flowering plants. The newly compiled Tree of Life will help scientists piece together the origins of flowering plants and inform future conservation efforts.
Approximately 90 percent of plants that live on land are flowering and fruiting plants called angiosperms. These flowering plants are essential to maintaining Earth's ecosystems, including storing carbon and producing oxygen, and they make up a large portion of our diet.
“Our very existence depends on them,” he says. william baker At the Royal Botanic Gardens in Kew, England. “That's why we need to really understand them.”
For the past eight years, Baker and his colleagues have been working to complete the Tree of Life, which describes the evolutionary relationships between all genera of plants and fungi.
Starting with flowering plants, the researchers designed molecular probes to search for 353 specific genes found in the nucleus of all angiosperms. “The nuclear genome is huge,” Baker says. “So we needed to focus on a specific set of genes.”
Researchers have so far sequenced the genes of 9,506 species of flowering plants, primarily using specimens from collections and public databases around the world. This represents nearly all known angiosperm families and approximately 8,000 of the 13,400 recorded genera.Some of the specimens collected in the analysis are more than 200 years old; Arenaria globifloraand many Guadalupe Island olives (Espererea Palmeri).
By comparing the similarities in the gene sequences of different flowering plants, researchers were able to figure out where they fit on the tree of life.
Baker says this is the most comprehensive survey of angiosperms to date. “We often liken it to the periodic table of elements,” he says. “It's the basic framework for life.”
angiosperm tree of life
Royal Botanic Gardens, Kew
Angiosperms emerged about 140 million years ago and have rapidly flourished, overtaking flowerless gymnosperms to become the world's dominant plant species. The sudden appearance of the diversity of flowering plants in the fossil record has baffled scientists for the past few centuries, and Charles Darwin called it “a hideous mystery.”
Now, the Tree of Life confirms that about 80 percent of the major flowering plant lineages that still exist today were part of this early boom in angiosperm diversity. “We can't say we've solved this 'damn mystery,' but at least we can say it really does exist,” Baker said.
The tree of life also highlights a further surge in diversity that occurred around 40 million years ago, possibly caused by a drop in global temperatures at the time.
In the future, he says, the Tree of Life could also help in the search for plants with pharmaceutical properties for new drugs. Ilia Leech, another member of Cue's team. It also helps scientists identify new species and assess which species are most vulnerable to climate change.
“This is the latest and greatest evolutionary framework for conducting new research that approaches the mechanisms that have allowed flowering plants to take over the world,” he says. ryan falk at Mississippi State University.
This image of an Inca city on Mars was taken on February 27, 2024 by the high-resolution stereo camera on board ESA’s Mars Express spacecraft. Image credit: ESA / DLR / FU Berlin.
“The Martian ‘spiders’ are not actual spiders, but form when spring sunlight falls on layers of carbon dioxide deposited during the dark winter,” said a member of the Mars Express team.
“Sunlight turns the carbon dioxide ice at the bottom of the layer into gas, which then accumulates and breaks through the ice sheet above.”
“During Mars’ spring, the gas explodes, dragging black material down to the surface as it progresses and shattering layers of ice up to a meter thick.”
“The resulting gas, laden with black dust, erupts through cracks in the ice in the form of tall fountains and geysers, before falling down and sinking to the surface.”
This creates a dark spot 45 m to 1 km (148 to 3,280 ft) in diameter.
This same process carves a distinctive “spider-shaped” pattern beneath the ice. Therefore, these black spots are evidence that a spider may be lurking underneath.
“Dark spots can be seen throughout the Mars Express image. But most of them can be seen as small specks in the dark region on the left, located just on the outskirts of a part of Mars called Inca City.” said the researchers.
“The reason for this name is no mystery: the network of linear, almost geometric ridges recalls Inca ruins.”
More formally known as Angustus Labyrinth. Inca City was discovered in 1972 by NASA’s Mariner 9 spacecraft.
“We still don’t know exactly how Inca cities formed. Sand dunes may have turned to stone over time,” the scientists said.
“Perhaps materials such as magma or sand are seeping through fractured sheets of Martian rock. Alternatively, the ridges could be ‘eskers,’ tortuous structures associated with glaciers.”
“The ‘walls’ of Inca cities appear to be part of a larger circle, 86 km (53.5 miles) in diameter.”
Scientists suspect that Inca City is located inside a large crater formed when rocks from space collided with the planet’s surface.
“This impact may have caused the fault to ripple in the surrounding plains, which was then filled with rising lava and then worn away over time,” the researchers said.
President Biden is anticipated to sign legislation mandating that TikTok’s Chinese owner divest the social media app’s U.S. operations or face a ban once it is passed by the Senate.
Biden has affirmed his intention to sign the bill, which is part of a foreign aid package for Ukraine, Israel, and Taiwan.
Below is an overview of the bill and its implications.
How does the law enable sales or bans?
The legislation gives TikTok’s parent company, Dance Corp. based in Beijing, 270 days to sell the app’s U.S. operations. Upon nearing the deadline, the president can grant a 90-day extension if ByteDance is near finalizing the deal. If the bill passes this week, the deadline coincides with the presidential inauguration on January 20th. This means that the decision to extend the sale process may rest with Donald Trump depending on the election outcome.

Failure by ByteDance to complete any sales would result in a nationwide ban by restricting app stores and web hosts from distributing TikTok.
Why is the US considering banning TikTok?
US lawmakers and authorities are worried about the possibility of the Chinese government accessing the data of TikTok’s 170 million American users under national security laws. Director of the FBI, Christopher Wray, stated that ByteDance is “influenced by the Chinese government” and Chinese officials manipulated TikTok’s algorithms. He cautioned that this could jeopardize individuals and allow governments to gather user data for espionage purposes.
TikTok refutes allegations of the Chinese government attempting to access U.S. user data and asserts denial of such requests. During a congressional hearing last year, TikTok’s CEO, Shou Zhi Chu, clarified: “ByteDance does not operate in China or any other country.”
Will TikTok challenge this legislation?
TikTok has pledged to contest the bill in court post its enactment, arguing that it violates the First Amendment safeguarding free speech.
“After the bill becomes law, we plan to file a legal challenge in court,” stated Michael Beckerman, TikTok’s head of public policy for the Americas, in a weekend memo to staff. He emphasized: “We will persist in opposing this bill as it infringes upon the First Amendment rights of the 170 million American TikTok users.”
The favorable tilt towards TikTok from the First Amendment was evident when a judge in Montana who previously banned the app overturned the decision, citing violation of users’ free speech rights.

In 2020, the U.S. attempted to ban TikTok following an executive order from President Trump, but a Washington judge blocked the ban, citing potential legal overreach. TikTok is expected to seek another injunction before challenging the constitutionality of the bill through a comprehensive lawsuit.
Who could potentially acquire TikTok’s U.S. operations?
Former U.S. Treasury Secretary Steve Mnuchin announced in March his intention to form a consortium to acquire TikTok’s U.S. assets, lauding it as a “promising investment.”
Microsoft had considered a deal to purchase TikTok in 2020 at the urging of President Trump. Additionally, President Trump advocated for U.S. tech company Oracle and retailer Walmart to acquire significant stakes in the company. ByteDance itself has several U.S. investors, including investment firms General Atlantic, Susquehanna, and Sequoia Capital.
Financial analysts at Wedbush Securities anticipate challenges in securing a sale involving TikTok’s algorithm, a crucial technology influencing app content curation. They emphasize the complexity of the sales process without the algorithm’s inclusion.
If ByteDance fails to make the sale, it could face a nationwide ban by blocking app stores and web hosts from distributing TikTok. Photo: Sheldon Cooper/SOPA Images/Rex/Shutterstock
What is the stance of the Chinese government?
Last year, the Chinese government expressed strong opposition to the app’s sale, stating that it would undermine global investor confidence in the U.S., including China. China’s export regulations also restrict the sale of specific technologies.
Will other nations replicate this divestment or ban?
TikTok faces scrutiny in other Western countries due to data concerns. It is prohibited on government-issued mobile devices in the UK, US, Canada, and New Zealand. Employees of the European Commission are also forbidden from using it on work-provided devices.
Calls for banning TikTok in the UK have been made, with former Conservative Party leader Iain Duncan Smith stating: “We should have done it ourselves.”
In 2020, India banned TikTok and numerous other Chinese apps, citing threats to national sovereignty, defense, and security.
The National Oceanic and Atmospheric Administration (NOAA) is providing millions of dollars to help traditionally underserved coastal communities combat climate change. This funding includes a significant stretch of 12,000 square miles of land spanning from North Carolina to Florida, known as the Gullah-Geechee Cultural Heritage Corridor. Designated by Congress in 2006, this land increases the wealth of the Gullah-Geechee by allowing communities along the corridor to utilize federal funds for programs and projects and receive technical and financial assistance from the National Park Service, all in an effort to protect and preserve their history and culture.
In April 2023, NOAA also announced over $265 million in funding for 38 new projects aimed at strengthening the climate resilience of coastal ecosystems and communities. These projects include initiatives in South Carolina to accelerate living shoreline projects in underserved communities, as well as collaborations with the Gullah-Geechee Cultural Heritage Corridor to create living shoreline projects in these communities. Additionally, the funding includes $6.2 million for programs supporting the Regional Ambassador Program for Coastlines.
NOAA-recommended projects involve hiring new staff to assist restoration organizations in building relationships with the Gullah-Geechee community, identifying resiliency priorities for community members, and establishing local relationships to support future restoration efforts. Moreover, $536,000 has been allocated to form an advisory committee.

Tia Clark operates Casual Club with Tia in Charleston, South Carolina, focusing on catching blue crabs, a staple in Gullah-Geechee cuisine. She participates in a conservation effort to build oyster reefs and create habitat for marine life to thrive, as rising temperatures are endangering crab habitats. With blue crab populations at an all-time low in South Carolina in 2023, Clark emphasizes the need to protect these resources from further decline.
Clark collaborates with state agencies and local schools to educate students about the importance of preserving water resources for future generations, emphasizing the impacts of climate change on the environment and wildlife.
Numerous federal programs support the Gullah-Geechee Cultural Heritage Corridor, emphasizing the importance of combatting climate change to protect the land, water, and way of life cherished by those living along the corridor.
“We are dedicated to ensuring the survival and continuation of our traditions as native Gullah Geechee,” said Queen Couette. “We are committed to preserving our heritage for generations to come.”
TEnnis is one of those sports that only intermittently works well through video games. The odd major series like Pete Sampras, Virtua Tennis, and Smash Court come along, but more often than not we end up relying on old favorites (Take a Bow, Super Tennis). It's been 13 years since TopSpin 4 was released, and the title is considered to be an authentic simulation of the sport that people love. Still looking for a copy until today. But perhaps not anymore. 2K Games has finally produced a sequel. This is a true champion contender.
From the get-go, TopSpin 2K25 has all the details you'd expect from a modern licensed sports sim. All major stadiums and championships are here. However, the playing environment is only well-detailed and not the spectacular theater of photorealism you've come to expect from EA Sports. The opening roster features 25 star players, from Emma Laducane to Andre Agassi. The selection isn't huge, and the quality of the caricatures varies, but it's good enough, and 2K says they plan to add more in the future.
If you don't want to cosplay as Carlos Alcaraz, you can join the full career mode as your own player. Mine is shockingly adorned with his pink Lycra and neon yellow sunglasses, a look that looks like it could easily carry over into real life. There are exhibition matches that you can easily knock out against the AI or up to three friends (online or split screen), and you can also participate in ranked and friendly online tournaments. Your appearance and skillset are fully customizable with a variety of outfits earned through play or (a feature that now seems inevitable) by purchasing a season pass or browsing the store. is. It's great that you can also choose to build a player with a prosthetic leg.
Of course, what really matters is the experience on the court, and that's great. The control system is complex but easy to access, with joypad buttons giving you access to flat, slice, lob, topspin and drop shot options, with power controlled by how long you hold the button down. As with TopSpin 4, timing and positioning are important skills. This is not a Mario Tennis style hit and hope game. If you take your shot too early or too late, your shot will end up in the net, flying off into the top of the stands, or giving another player an easy smash. At the same time, you're always thinking about where your players are on the court relative to the shot you're about to make and the likely return from your opponent. The physical nature of very good players makes the decision-making process even more demanding. It reproduces the weight position and body momentum with delicate precision. Are you so proud of that rushing cross-court slice shot you just landed? Good luck getting back to baseline for Serena Williams' comeback.
For players used to the more visceral feel of Virtua Tennis or the generous forbearance of Mario Tennis, there's a tough learning curve ahead. This is highlighted by the presence of his TopSpin Academy, an in-depth instructional mode that steadily teaches players from basic ground strokes to advanced serve tactics and individual player techniques. Just learning the timing will require several hours of play. If you're just playing the odd knockabout with your friends, there's no need to stress too much, but if you want to progress through Career His mode or play against human opponents online, give yourself a “good” shot. It would be better to hit it. “Perfect” timing at least 75% of the time.
But this is a good thing. 2K Games has created a game that feels like a proper simulation in terms of the array of tactical options available at any given moment and the demands placed on the player's skill. By completing TopSpin Academy, I learned a lot about real tennis strategy and how professional players differ in the way they use their baseline and net plays. There's also plenty of room to grow as a player by experimenting with power shots, perfecting tricky drop shots, and redistributing player attribute points to support different tactical approaches. it is clear.
Thirteen years is a long time to wait for a new tennis sim, but TopSpin 2K25 is well worth it. If there's one thing this game teaches you, it's the value of determined patience.Well, and you can Looks great with pink Lycra and yellow sunglasses.
Sulfur and chlorine isotopes in Io’s atmosphere indicate that Io has been volcanically active throughout the solar system’s 4.57 billion-year history.
This global map of Io was obtained in January 1999 by NASA’s Galileo spacecraft. Image credit: NASA/JPL/University of Arizona.
Jupiter’s moon Io is the most volcanically active body in the solar system.
Io’s volcanic activity is the result of tidal heating due to friction that occurs within the moon’s interior as it is pulled between Jupiter and its neighboring moons Europa and Ganymede.
However, it is not fully understood how long this moon has hosted such extensive volcanic activity.
Due to the Moon’s current level of volcanic activity, Io’s surface is constantly being reworked, leaving only the most recent 1 million years of its geological record.
Stable isotope measurements of volatile elements in Io’s atmosphere could provide information about Io’s volcanic history.
“Io is a moon of Jupiter and is the most volcanically active body in the solar system,” says Dr. Ellie Hughes, a volcanic fluid geochemist at GNS Science.
“Io is in orbital resonance with Jupiter’s other two large moons, Europa and Ganymede.”
“For every time Ganymede orbits Jupiter once, Europa orbits twice and Io orbits four times.”
“This configuration causes Io’s orbit around Jupiter to be elliptical rather than circular, causing Jupiter’s gravity on Io to change periodically.”
“This change in gravity causes something called tidal heating on Io, just as the moon causes ocean tides on Earth, which causes volcanic activity.”
“However, it is unclear whether volcanic activity has occurred on Io over a long period of time or how this activity has changed over Io’s 4.57 billion year history.”
“Io has experienced so much volcanic activity that its surface is constantly being updated, leaving little trace of its past.”
“Fortunately, we can study Io back in time by studying sulfur and its isotopes.”
In the new study, Hughes, Caltech researcher Catherine de Clare, and colleagues used the Atacama Large Millimeter/Submillimeter Array (ALMA) to observe gases in Io’s tenuous atmosphere. , we measured stable isotope radio waves of sulfur and chlorine. Carries molecules.
Scientists believe that both elements have lower concentrations of heavier isotopes compared to the solar system average due to the loss of lighter isotopes from the upper atmosphere as material is continually recycled between Io’s interior and atmosphere. I discovered that it is very plentiful.
The findings show that Io lost 94% to 99% of its sulfur through this outgassing and recycling process.
This would require that Io maintained its current level of volcanic activity throughout its lifetime.
“Sulfur is released into the atmosphere from Io’s interior by tidal heating from volcanic activity,” Hughes said.
“Some of the sulfur is lost to space by Jupiter’s magnetosphere, a bundle of charged particles swirling around Jupiter that continuously bombards Io’s atmosphere.”
“The sulfur that is left behind will eventually be buried back inside Io, ready to start the cycle again.”
“Isotopes of the same element have different weights from each other, so they can behave slightly differently during this cycle.”
“We found that the sulfur lost to space on Io is a little lighter isotopically than the sulfur that is recycled into Io’s interior.”
“Thus, over time, the sulfur left on Io becomes isotopically heavier and heavier. How heavy it gets depends on how long the volcanic activity has been occurring.”
“We found much more isotopically heavy sulfur in Io’s atmosphere than the solar system average. This requires that Io has lost almost all of its original sulfur.”
“Based on numerical modeling, this means that Io has been volcanically active for billions of years, and that tidal heating and orbital resonance have also occurred for most of Io’s history.”
“In the future, variability in atmospheric sulfur isotopic composition may help quantify Io’s average tidal heating rate.”
Tesla’s efforts to make electric cars more affordable are making progress.
After announcing plans to speed up production and start manufacturing low-cost EVs sooner than expected, Tesla’s stock price surged by 12% on Tuesday.
Investors are eager to see what Tesla has in store and how quickly these new vehicles will be available.
What is Tesla planning?
Tesla is reworking its production timeline to launch new models faster.
The company updated its vehicle lineup to accelerate the introduction of more affordable models before the previously projected start date of late 2025.
Elon Musk, President of Tesla, mentioned that production could begin as early as this year or by early 2025.
While details about the design and specifications of the new car remain scarce, it’s known that Tesla had previously discussed creating a cheaper vehicle, referred to as the Model 2, priced below $25,000.
How can I achieve this?
To ramp up production of affordable cars, Tesla may need to modify its Model 2 program.
The company aimed to implement a new manufacturing process that would reduce production costs by half, but this will require substantial investment.
Recent announcements indicate that Tesla plans to build the new vehicle on its current production line, steering away from innovative manufacturing technologies.
Some experts believe this shift signals the abandonment of the Model 2 plans in favor of continuing to produce existing models.
How much does a more affordable car cost?
The exact price of the upcoming “more affordable” model remains unknown, but Tesla initially aimed for a $25,000 price tag to compete with Chinese electric vehicle manufacturers.
However, revised plans suggest that cost savings may not meet previous expectations.

Harry Daniels stakes out celebrities like Dua Lipa, Katy Perry, Ellie Goulding, and Joe Biden and serenades them while filming their reactions on TikTok. Most of these exchanges are spontaneous, as if the celebrities are genuinely surprised to have a 20-year-old man sing a song to them (usually horrifyingly, often about themselves). When Daniels found Jacob Elordi, who was at the restaurant, said the Saltburn star stayed next to a bodyguard-like man across the room and watched, amused, as Daniels headed off to the dance floor singing “Murderer.” I was a little wary.

Daniels’ videos alternate between old-fashioned trolling (Daniels once gratefully sang to Lea Michele, “All I Can Do for the Illiterate Community”) and an expression of true love for the artist. In an age when celebrities tightly control their images, his improvisations manage to reveal whether there’s a sense of humor, a lick of personality, or something going on beneath the surface. To quote a popular genre of comments Daniels receives on TikTok: “How do I find these people?!?!?”
Daniels has long cultivated an obsession with pop princesses online. “I think there’s a big element of escapism in stan culture,” he told me last week when I met him and his sister Madeline Daniels at a cafe on New York’s Lower East Side. “I found solace in other people’s careers and jobs, because I often felt insecure about my own life.”
Daniels grew up on Long Island, the son of an accountant and a homemaker. “Harry first attended Stan University when he was about 11 years old, where he completed his PhD,” said Madeleine, who also serves as his cameraman and unofficial manager. He loves Demi Lovato, Billie Eilish, Fifth Harmony, and Haim, and learned how to follow his favorites in real life by interacting with their fans on social media.
Two years ago, Daniels used his superior education to compete for face time with superstars. “I went to everyone’s shows and meet-and-greets and engaged with them in a way that made me feel connected to them,” he said. However, he felt the interaction was too formulaic. “How many times do I say ‘I love you so much’ to someone?” Wanting to leave a lasting impression, he decided to entertain himself by being a damn, a troll.”

Daniels’ first recorded TikTok serenade was at Sabrina Carpenter’s album signing in 2022. In the video, Sabrina Carpenter sang her diss track “Skin” while sitting behind a table. He suppressed an obviously nervous laugh. As soon as Daniels finished speaking, Carpenter issued a very diplomatic “thank you.” At that moment, a fool was born.
Daniels quickly became “smarter” than he appeared in person. He was waiting outside the Broadway stage door. He serenaded Sarah Paulson. Sometimes he got lucky. One night while he was eating at a diner, he ran into Ethan Cutkosky, who played Carl in the American version of Shameless.
“I think people think I’m hiding in the bushes, but I actually just show up where I know they’ll be,” he said. (It helps that he lives just outside New York City.)
Eventually, Daniels reached such a level of virality that some artist teams started reaching out. The music industry’s heavy reliance on TikTok as a promotional tool means that labels are likely to back artists who can generate buzz on the app. A cleverly planned “surprise” with Daniels, who has over 1 million followers, is a boon for artists looking to go viral or curate a relatable online persona.
Ripa’s team invited Daniels to surprise their star during a press tour. Similarly, Daniels used backstage access to go to Coachella earlier this month and sing Taylor Swift’s “Antihero” to Jack Antonoff and Paris Hilton’s “Stars Are Blind” to the heiress herself. Daniels says many of his videos are “just for fun,” meaning he doesn’t get paid. Money comes in when sponsors pay him to take pictures with artists at events. (Daniels declined to reveal his maximum performance fee.)
Daniels said that while the artist’s team may know what’s going on, the artist “legitimately doesn’t know anything,” which makes it difficult for the created situation to remain authentic. He claims it’s helping. “But lately, people have started trying to teach me how to create their own content.” He says he’s been asked by artists to promote new music or promote the names of products. “I wanted my videos to be less commercial and more culturally relevant, so I had to put my foot down,” he said.
Although Daniels prefers to stay in the pop culture realm, he recently filmed a video with Biden after receiving an invitation to a star-studded Radio City Music Hall fundraiser in March. Daniels was able to get close to the barricade where Biden walked around shaking hands with attendees. So he learned to sing Lana Del Rey’s national anthem dedicated to the 81-year-old politician. “He was very present, but I think he was literally like, ‘What the heck?'” Daniels said.

Daniels also intended to sing for Kamala Harris if given the chance. What song? Of course, the wheels of the bus are “The Vice President’s Obvious Love” laugh out loud about buses, laugh out loud about buses. But don’t expect a Trump video. “I don’t think I’ll ever get this close to him,” Daniels said.
Not everyone appreciates Harry Daniels’ treatment. At a Biden fundraiser afterparty, Ms. Daniels unsuccessfully tried to sing to the incomparable Anna Wintour, the editor-in-chief of Vogue: I may be a troll, but I’m not stupid,” Daniels said. “So I introduced myself and said I was a fan of hers, and she was like, ‘Thank you, that’s so sweet.’ I started singing and she just walked away.”
Daniels also came under heavy attack after the match. Ask America Ferrera if she wanted a “gay son or creepy daughter” at the People’s Choice Awards. His critics accused him of being “uninteresting” and “not a real journalist.” He dismissed that, telling Rolling Stone, “My job is to create content that generates clicks and views.”
Daniels’ post has an ulterior motive. According to Rolling Stone, he’s also a singer himself, and he’s not bad at it. The magazine said his vocals had “an inherent melancholy similar to that of Troye Sivan.” “The only reason I really started doing all of this is because I wanted to pursue music. Basically, everyone I’ve ever talked to in this industry has told me that you need to get a following on social media. I said it consistently,” Daniels said. “So if people want a follow, I’ll give them a follow.”
Daniels doesn’t seem annoyed by the give-and-take. He respects the hustle and bustle. Still, there’s something dark about how his outsider side inevitably becomes part of the star machine. The more celebrities are tipped off about a potential interaction with Harry Daniels, the more the video feels like an SNL short, less gonzo fun and more fuel for PR campaigns and album release calendars.

Regardless, Daniels says, “The music comes first.” He describes his work as hyperpop, a bubblegum-meets-chaos genre typified by Charli XCX and Kim Petras. “It’s larger than life and reminds me of what music is supposed to be. Music is supposed to soundtrack something bigger than yourself and make you feel things you can’t put into words,” he said.
Although he hasn’t released any tracks yet, he said 2024 will be the last year of his current idiocy. He’s not done yet. He knows that if he wants to stay relevant, he’ll have to create content forever, and that’s fine with him. He just sees it as an opportunity to “strike while the iron is hot.” He is currently in talks to expand the Homespun team to include not only his sister but also the pros.
As Daniels left the cafe, a young woman who appeared to be a fan standing near the exit quietly said, “I love you.” Daniels breathlessly responded with a sweet, “I love you too.” I’m sure it’s something he inherited from the celebrities he’s sung to.
From the moment you begin as an immature egg in your grandmother’s womb, your fertility journey is limited. However, scientists at Cambridge University may soon change that reality in their bright labs.
Dr. Staša Stankovic is one of these scientists. Her research at Addenbrookes Hospital in Cambridge has uncovered valuable data in the field. Now, Stankovic is focused on unraveling the mysteries surrounding fertility and menopause.
Women’s ovaries hold a finite supply of eggs that represent their fertility. Stankovic compares this concept to an hourglass, where the sand (eggs) can only flow in one direction until it runs out, signaling the onset of menopause.
“In science, we aim to control the hourglass’s middle part,” she explains. “Our goal is to limit the eggs’ loss over time, preserving the highest quality eggs for as long as possible.”
Working with a team for five years, Stankovic is developing a method to predict the natural fertile period and age of menopause with 65% accuracy, aiming for 80% accuracy in clinical practice.
Additionally, the team is exploring potential drug solutions to address infertility and potentially delay menopause. The onset of menopause is influenced by the ovarian reserve and the rate at which eggs deplete over a woman’s lifetime, typically occurring around age 50 with fewer than 1,000 eggs left.
For women experiencing early menopause or premature menopause, these drug treatments could be life-changing.
Your Menopausal Age
Researchers are studying genetic factors using a blood sample rather than physical examinations to understand how genes impact fertility and menopause.
The research team analyzed data from over 200,000 women in the UK Biobank, which provided insights into menopause, fertility, and overall health metrics. This data will help researchers make connections with other health outcomes like dementia and diabetes.
By identifying over 300 genetic variations linked to menopause, researchers foresee potential solutions for ovarian diseases and early menopause using drug interventions.
Stankovic cautions against relying solely on IVF and egg freezing as magical solutions, emphasizing the need for more effective treatments with higher success rates.
Effects of Delaying Menopause
The research team is hopeful about developing infertility drugs that not only address symptoms but also regulate ovarian function. While the drug’s availability is estimated within the next decade, rigorous testing and validation are still required.
The team’s focus is on identifying crucial genes, conducting testing in ovarian models, and formulating drugs that maintain egg quality and quantity as women age.
Ultimately, the goal is to delay menopause and extend reproductive lifespan. Preliminary studies on mice have shown promising results, but further research is needed before human trials can begin.
Aside from fertility benefits, delaying menopause could also impact women’s overall health, offering insights into various diseases associated with menopause.
