The surface of the moon as captured from orbit prior to the crash
ISPACE SMBC X Hakuto-R Venture Moon
On June 5th at 7:13 PM, a Japanese space endeavor aiming to be the third private lunar landing failed as ISPACE’s Resilience lander succumbed on the moon’s surface.
The lander began its descent from around 20 km above the moon, but ISPACE’s mission control quickly lost communication after the probe activated its main engine for final descent, receiving no further signals.
The company announced that the laser tool used to gauge the distance to the surface seemed to malfunction, leading to inadequate slowing of the lander and likely resulting in a collision.
“Given the absence of a successful lunar landing at this time, our top priority is to analyze the telemetry data collected so far and diligently investigate the cause,” stated ISPACE CEO Mr. Takeshi.
Had it succeeded, Resilience would have marked the second private moon landing of the year and the third overall, making it the first non-U.S. company to land on the moon after ISPACE’s prior attempt, the Hakuto-R mission, failed in 2023.
The Resilience Lander embarked on its lunar journey aboard a SpaceX rocket on January 15th, alongside Firefly Aerospace’s Blue Ghost lander. While the Blue Ghost successfully landed on March 2, Resilience took a more circuitous route, moving into deeper space before returning on May 6 to enter lunar orbit. This complex trajectory was essential for targeting the challenging northern plain called Male Frigolis, which had not been surveyed by previous lunar missions.
Equipped with six experiments, the lander included a device for splitting water into hydrogen and oxygen, a module for algae-based food production, and a radiation monitor for deep space. Additionally, it housed a five-kilogram rover named Tenesial, designed to explore and capture images of the moon during the two weeks that Resilience was set to operate.
Fast Radio Bursts (FRBs) represent one of the greatest mysteries of the universe in our time. Initially identified in 2007, these transient radio wave phenomena have perplexed astronomers ever since.
Although we have detected thousands of them, the precise causes, origins, and unpredictable behaviors of FRBs remain elusive.
Just when scientists thought they were starting to unravel the mysteries, two new studies published in January 2025 added twists to the ongoing FRB enigma, challenging earlier theories.
“The FRB is one of those cosmic mysteries that deserves to be solved,” states Dr. Tarraneh Eftekhari, a radio astronomer at Northwestern University, in reference to the first new paper published in Astrophysics Letter.
Though the solution may be a long way off, the universe continues to guard its secrets.
What Makes the FRB Mysterious?
While it may not be entirely accurate to say that FRBs were discovered purely by chance, their initial detection happened within data collected for an entirely different purpose.
Pulsars, or “pulsating radio sources,” are far better understood cosmic phenomena, having been discovered in 1967 by Professor Jocelyn Bell Burnell, arising from neutron stars. These are incredibly dense remnants of giant stars boasting magnetic fields far stronger than Earth’s.
These rapidly spinning stellar remnants emit regular pulses of radio waves akin to cosmic beacons.
The consistency of these pulses and their emissions at specific frequencies initially led to the hypothesis that they could be of natural origin, which earned the first pulsar the nickname “Little Green Man 1.”
While pulsars quickly found their rightful place in astrophysics, FRBs tell a different story.
Jump forward to 2007 when they emerged unexpectedly from data gathered by the Parkes Multibeam Pulsar Survey, an international collaboration involving Jodrell Bank Observatory, Massachusetts Institute of Technology, Bologna Astronomical Observatory, and Australia’s National Facilities.
The emission from this event was so powerful that it overshadowed all other known sources at the time by a substantial margin.
“In terms of energy output, a 1-millisecond-long FRB can emit as much energy as the Sun produces over three days,” says Dr. Fabian Djankowski, an astrophysicist at the French National Centre for Science and Technology specializing in FRBs.
However, for over five years after the initial detection, no similar events were recorded. Skepticism faded as more FRBs began to emerge.
Thousands have been detected since then, and astronomers estimate that two or three FRBs may blaze across the sky every minute.
These enigmatic signals release immense energy from deep space, illuminating the sky with their mysterious nature. And the strangeness does not end there.
Initially, FRBs were believed to be one-off occurrences, cosmic anomalies. This assumption seemed valid, as follow-up observations failed to reveal any repeating sources.
That changed in 2016 when FRB 121102 was found to emit repeated bursts. Currently, between 3% and 10% of FRBs are classified as “repeaters.”
Why do some FRBs remain silent after a single burst, while others emit multiple bursts? This is yet another mystery awaiting resolution.

What Causes FRBs?
Numerous hypotheses have been proposed regarding the cause of FRBs, ranging from chaotic black hole collisions to extraterrestrial signals. Many explanations have emerged, including the unlikely scenario of a microwave being accidentally detected. However, one candidate seems to rise above the rest.
“When massive stars collapse and go supernova, they leave behind highly magnetized neutron stars, or ‘magnetars,'” notes Eftekhari. “The reason magnetars are a compelling candidate for FRBs is that we have observed similar events emanating from known magnetars within our Milky Way.”
Neutron stars already possess strong magnetic fields, but magnetars are in a category of their own, with magnetic fields thousands of times stronger than those of typical neutron stars.
Furthermore, a higher frequency of FRBs has been detected in galaxies with rapid star formation. As Eftekhari explains, “To produce a supernova that results in a magnetar, a massive star is required, and these giant stars are found in star-forming galaxies.”
So, is the case settled? Not quite.

This is where the two new studies published in January 2025 come into play, both examining the recurring FRB known as 20240209A.
“The first exciting aspect of this FRB is that it originates outside our galaxy,” says Vishwangi Shah, a doctoral student at McGill University, referencing the second study.
“There is only one other FRB detected outside our galaxy. In terms of its repeaters, I believe it originates from a globular cluster.”
Both Eftekhari and Shah suggest that 20240209A is also associated with globular clusters (dense groups of ancient stars existing on the outskirts of galaxies).
“This is remarkable,” Eftekhari comments. “The notion of magnetar progenitors poses a challenge since they typically require a group of young stars to form magnetars.”
So what does this mean for FRBs? One possibility is that magnetars are still the culprits, but they may be generated through entirely different mechanisms.
For instance, within these stellar graveyards, two normal neutron stars might combine to form magnetars. Alternatively, a white dwarf—a stellar remnant too small to evolve into a neutron star—could gather material from a nearby companion, culminating in a massive explosion that results in a magnetar.
Ultimately, the exact origin of these outlier events remains unknown. “It’s thrilling to contemplate that we might be dealing with a subpopulation of FRBs,” Eftekhari remarks. “This case isn’t as clear as it appears.”
Can We Determine the Origins of FRBs?
Despite nearly two decades of research, many questions regarding FRBs linger. Which objects are responsible? What processes drive these phenomena? And why do some FRBs repeat while others do not?
Thanks to advances in FRB detection technology, answers may be nearer than anticipated.
CHIME is currently undergoing enhancements aimed at pinpointing bursts with unprecedented precision.
This advancement in FRB detection represents great progress in unraveling their mysteries. While many FRBs have been observed, accurately identifying their environments has left several key questions regarding their origins unanswered.
Jankowski believes that in the near future, many cases like 20240209A could be unlocked, revealing their underlying mechanisms. “I anticipate significant progress in the coming years,” he adds.
The Square Kilometer Array (SKA), a massive observatory spanning Australia and South Africa, aims to join the search for FRBs shortly.
Eftekhari and Shah have also proposed utilizing the James Webb Space Telescope to explore the region where 20240209A was detected.
“It’s an incredibly exciting time for FRB research,” highlights Jankowski. “We are poised to make remarkable discoveries in the next few years.”

A 12-week study involving 72 pre-diabetic adults revealed that the consumption of either chickpeas or black beans positively influences inflammation markers in diabetic patients. Additionally, chickpea intake helps in cholesterol regulation.
Incorporating one bean daily can yield significant benefits for both heart and metabolic health. Image credit: PDPICS.
“Pre-diabetic individuals often exhibit poor lipid metabolism and persistent low-grade inflammation, both of which can lead to diseases like heart disease and type 2 diabetes.”
“Our findings indicated that levels of tofu remained constant, yet they may aid in lowering cholesterol within pre-tofu individuals while also diminishing inflammation.”
While black beans and chickpeas are widely consumed, they are frequently neglected in extensive studies examining their effects on cholesterol and inflammation in those at risk for heart disease and diabetes.
This research forms part of a broader project investigating how the intake of black beans and chickpeas influences inflammation and insulin response mediated by intestinal microbiome activity.
“Our study highlights the advantages of bean consumption for pre-diabetic adults, but these legumes are excellent choices for everyone,” stated Smith.
“These insights can help shape dietary recommendations, clinical practices, and public health initiatives aimed at preventing heart disease and diabetes.”
To enhance the practical relevance of the research, the study was conducted with participants in their natural living environments.
Participants were randomly assigned to consume either 1 cup of black beans, chickpeas, or rice (the control group) over the span of 12 weeks.
Blood samples were collected at baseline, 6 weeks, and 12 weeks to monitor cholesterol levels, inflammation, blood glucose, and glucose tolerance tests were administered at both the beginning and conclusion of the study.
The group consuming chickpeas saw a significant drop in total cholesterol, from an average of 200.4 milligrams per deciliter at the start to 185.8 milligrams per deciliter after 12 weeks.
In the black bean group, the average level of the inflammatory cytokine interleukin-6, which is a marker for inflammation, decreased from 2.57 picograms per milliliter at baseline to 1.88 picograms per milliliter after 12 weeks.
No noteworthy changes were noted in markers of glucose metabolism.
“Switching to healthier alternatives, like canned, dried, or frozen beans, is an excellent starting point for those looking to increase their bean intake,” explained the scientist.
“However, it’s crucial to watch for extra ingredients like salt and sugar based on your selections.”
“There are numerous ways to include beans in your regular diet as a budget-friendly method to enhance your overall health and lower the risk of chronic ailments,” Smith added.
“You can blend them to thicken soups, use them as salad toppings, or combine them with other grains like rice or quinoa.”
The findings were reported in a presentation on June 3rd during the Nutrition 2025 annual meeting held by the American Nutrition Association.

Fossilized blue-staining bacteria that inhabit coniferous wood, drawing the interest of insects. Xenoxylon Phyllocladoides from the Jurassic Tier Ojisian Formation in China extends the early fossil history of blue-stained bacteria by around 80 million years, reconstructing the evolutionary timeline of this fungal group and offering fresh perspectives on the evolution of ecological relationships with wood-boring insects.

Blue staining bacteria form a distinctive group of wood-inhabiting fungi that do not have the capacity to degrade lignocellulose but can cause significant discoloration, particularly in conifers.
Generally, these fungi are not fatal to their hosts, though they can hasten tree mortality when linked with wood-boring insects.
Recent molecular phylogenetic studies suggest that blue-stained bacteria may represent an ancient group of fungi that existed during the late Paleozoic or early Mesozoic eras.
However, the geological aspects of blue-staining bacteria remain largely unexplored.
“Until 2022, the earliest confirmed fossil evidence of blue-staining bacteria was identified from the Cretaceous period in South Africa, around 80 million years ago,” stated Dr. Ning Tian, a paleontologist at Shenyang Normal University.
Dr. Tian and colleagues uncovered well-preserved fossilized hyphae from a 160-million-year-old petrified forest of Xenoxylon Phyllocladoides from the Tier Ojisian Formation in Northeast China.
“Microscopy revealed darkly pigmented fossil hyphae, resembling the characteristics of modern blue-staining bacteria responsible for forest discoloration,” they noted.
“Notably, when penetrating woody cell walls, hyphae usually form a specialized structure known as permeation pegs.”
“As they invade the wood cell walls, the mycelium tends to be finer and can more easily navigate this robust barrier.”
“The discovery of these penetrating pegs allowed us to confirm that the fossilized bacteria we encountered belong to the blue-stained fungal group.”
“Unlike wood-decomposing fungi that break down wood cell walls through enzyme secretion, blue-staining bacteria lack the enzymatic ability for wood degradation.”
“Instead, their mycelium breaches the wood cell wall mechanically using these penetrating pegs.”
“This discovery of Jurassic blue-staining bacteria from China marks the second report of such fungi and adds to the early fossil record of this group worldwide, as recognized by Nanjing Institute of Geology and Paleontology.”
“It also sheds light on the ecological interactions between blue-staining bacteria, plants, and insects during the Jurassic period.”
The bark beetle subfamily Scolytinae is considered a major spore disperser for present-day blue stain fungi.
However, molecular and fossil data indicate that Scolytinae likely originated before the early Cretaceous period.
Given the current Jurassic age of the fossil fungi, it is proposed that the spore dispersing agent was not Scolytinae but another wood-boring insect prevalent during that time.
The findings are detailed in a paper published in the June 2025 issue of the journal National Science Review.

Researchers have successfully conducted the first real-time 3D simulation demonstrating how a powerful laser beam alters the quantum vacuum. Remarkably, these simulations reflect the unusual phenomena anticipated by quantum physics, known as vacuum four-wave mixing. This principle suggests that the combined electromagnetic fields of three laser pulses can polarize a virtual electron-positron pair within a vacuum, resulting in photons bouncing toward one another as if they were billiard balls.

This allows the generation of a fourth blue laser beam in a unique direction and color, conserving momentum and energy. Image credit: Zixin (Lily) Zhang.
“This is not merely a matter of academic interest. It represents a significant advance toward experimental validation of quantum effects, which have largely remained theoretical,” remarks Professor Peter Norries from Oxford University.
The simulation was executed using an enhanced version of Osiris, a simulation software that models interactions between laser beams and various materials or plasmas.
“We are doctoral students at Oxford University,” shared Zixin (Lily) Zhang.
“By applying the model to a three-beam scattering experiment, we were able to capture a comprehensive spectrum of quantum signatures, along with detailed insights into the interaction region and the principal time scale.”
“We’ve rigorously benchmarked the simulation, enabling our focus to shift to more intricate, exploratory scenarios, like exotic laser beam structures and dynamic focus pulses.”
Crucially, these models furnish the specifics that experimentalists depend on to design accurate real-world tests, encompassing realistic laser configurations and pulse timing.
The simulations also uncover new insights into how these interactions develop in real-time and how subtle asymmetries in beam geometry can influence the outcomes.
According to the team, this tool not only aids in planning future high-energy laser experiments but also assists in the search for evidence of virtual particles, such as axes and millicharged particles, or potential dark matter candidates.
“The broader planned experiments at state-of-the-art laser facilities will greatly benefit from the new computational methods implemented in Osiris,” noted Professor Lewis Silva, a physicist at the Technico Institute in Lisbon and Oxford.
“The integration of ultra-intense lasers, advanced detection techniques, cutting-edge analysis, and numerical modeling lays the groundwork for a new era of laser-material interactions, opening new avenues for fundamental physics.”
The team’s paper was published today in the journal Communication Physics.

The Centers for Disease Control and Prevention reports that a Texas woman died from an infection linked to an amoeba after using tap water for sinus irrigation, which ultimately led to brain damage Case report.
The 71-year-old woman, who was otherwise healthy, experienced severe neurological symptoms, including fever, headache, and altered mental status, four days after using tap water from the RV’s water system to fill her nasal irrigation device at a Texas campground.
She received treatment for primary amoebic meningoencephalitis, an infection caused by Naegleria fowleri, often referred to as the “brain-eating amoeba.” Despite medical intervention, she suffered a seizure and succumbed to the infection eight days post-symptom onset, according to the CDC.
Laboratory tests confirmed the presence of the amoeba in the woman’s cerebrospinal fluid.
The CDC noted that while infections commonly occur after recreational water use, using undistilled water for sinus irrigation is also a significant risk factor for primary amoebic meningoencephalitis.
A survey conducted by the agency revealed that although the woman had not been recently exposed to freshwater, she had used non-boiled water from the RV’s drinking water tap for nasal irrigation multiple times prior to her illness.
According to the survey findings, the RV’s drinking water tanks were filled and potentially contained contaminated water before the RV was purchased three months earlier. The investigation concluded that contamination could have originated from local government water systems linked to the drinking water systems and bypassing the tanks.
The agency underscores the importance of using distilled, sterilized, or previously boiled and cooled tap water for nasal irrigation to lower the risk of infection or illness.
Retinal implants have shown potential in restoring vision in blind mice, indicating that they may eventually help those with conditions like age-related macular degeneration, where photoreceptor cells in the retina deteriorate over time.
Shuiyuan Wang from Fudan University in China and his team developed a retinal prosthesis composed of metal nanoparticles that replicate the function of lost retinal cells, converting light into electrical signals to be sent to the brain.
In their experiments, the researchers administered nanoparticles into the retinas of mice that had been genetically modified to be nearly completely blind.
They restricted water access for three days to both the modified blind mice and those with normal vision. Subsequently, they trained all mice to activate a 6cm wide button on a screen to receive water.
Following training, each mouse underwent 40 testing rounds. The fully sighted mouse pressed the button successfully 78% of the time. Mice with implants achieved a 68% success rate, while untreated blind mice only managed 27%. “That presents a very noticeable effect,” stated Patrick DeGenard, who wasn’t involved in the research but is affiliated with Newcastle University in the UK.
After 60 days, researchers observed minimal signs of toxicity from the implants in the mice. However, Degenaar emphasized the need for long-term safety data, stating, “For clinical application, extensive animal testing lasting approximately five years will be necessary.”
“Patients with age-related macular degeneration and retinitis pigmentosa could benefit from this prosthetic,” noted Leslie Askew from the University of Surrey, UK, who was not part of the study.
Degenaar also remarked that justifying this solution for age-related macular degeneration patients is complex, as they possess a degree of vision that may not warrant the risks associated with implanting prosthetics.
Furthermore, he noted that mice generally have inferior vision compared to humans, raising uncertainty about how beneficial the findings will be for people until comprehensive clinical trials are conducted.
Taurine supplements are seen as potentially effective in slowing aging, but this may not hold true

While it was previously thought that taurine, an amino acid, diminishes with age, research in animals suggested that taurine supplements might help slow down the aging process. New studies, however, indicate this decline is not consistent. In fact, taurine levels often increase with age, indicating that low nutrient levels might not be the primary factor driving aging.
Earlier research indicated that taurine levels decrease in aging men, with those exhibiting higher taurine levels at age 60 experiencing better health outcomes. This correlation suggests low taurine levels might contribute to aging, supported by evidence that taurine supplements can extend the lifespans of mice and monkeys.
The challenge lies in the fact that taurine levels can fluctuate due to various factors, including illness, stress, and dietary habits. Thus, a reduction in this vital amino acid may not be directly linked to the aging process. Maria Emilia Fernandez and her team from The National Institute of Aging in Maryland assessed taurine levels in 742 individuals aged 26 to 100. The cohort consisted of roughly equal numbers of men and women, with no major health issues and multiple blood samples taken between January 2006 and October 2018.
On average, women aged 100 had taurine levels that were nearly 27% higher than those aged 26, while men aged 30 to 97 exhibited an approximate 6% increase. Similar trends were noted among 32 monkeys sampled at ages ranging from 7 to 32 years, where female monkeys saw taurine levels rise by an average of 72% and male monkeys by 27% between ages 5 and 30.
These results underscore that taurine levels may not be a reliable indicator of aging. Importantly, taurine concentrations vary widely among individuals and can change over time due to external factors, according to Fernandez.
Nevertheless, some individuals may still find taurine supplementation beneficial. Fernandez highlights research indicating its potential to help regulate blood glucose levels in people with type 2 diabetes or those who are obese. However, the question of whether taurine can slow aging in otherwise healthy individuals remains unanswered.
Vijay Yadav from Rutgers University and his colleagues are currently leading clinical trials on taurine supplementation in middle-aged adults. “We aim to conclude the trial by the end of 2025,” he states. “Our goal is to produce robust data to determine if taurine supplementation can decelerate human aging or enhance health and fitness.”
What should a tiny millimeter worm do when food is scarce? The solution lies in teaming up with countless companions to form tentacle-like structures that can bridge gaps to nearby objects or capture larger prey to aid in their journey.
Researchers examining nematode worms in laboratory settings have long observed their ability to construct “towers,” yet these phenomena lacked thorough exploration, states Serenadine from the Max Planck Institute for Animal Behavior in Germany. Therefore, she and her team aimed to investigate this further.
The research focused on the Caenorhabditis elegans worm species. In their experiments, when food was inadequate, and given a structure to assemble, a significant number of worms tended to create towers. For these studies, they utilized toothbrush bristles as a base.
While worms occasionally formed towers without any physical support, these structures were typically under 5 mm tall and only lasted about a minute. In contrast, when built upon the bristles, the towers reached heights of 11 mm and could endure for up to half a day.
In other nematode species, reports indicate towers can grow as tall as 50 mm. “They can expand significantly,” notes Din.
Although the base of the tower remains steady, the upper portion can extend well beyond the support and exhibit movement similar to tentacles. This allows the towers to reach out to nearby surfaces, forming bridges that enable the worms to traverse much wider gaps than individual organisms could manage.
“Tower” of nematode worms on rotten apples
Perez et al. Current Biology (2025)
The towers are capable of gripping objects that come into contact with them, such as fruit fly legs, effectively hitching a ride for the worms. This allows them to travel further without exerting their own energy.
While it’s known that individual nematodes can latch onto insects for transportation, the idea that an entire tower could do the same was previously unverified. “That’s a feature we expect to observe,” says Ding.
Utilizing a digital microscope, the researchers documented the tower’s formation on a decaying apple in an orchard adjacent to their laboratory.
Worm towers are exclusively formed by a single species, despite the presence of various species around them. They can consist of worms at any stage of their life cycle, even if the team discovers them during the process. Previously, it was believed that only “Dawer” worms, which are in their hard larval stage during stressful conditions, could create these towers.
There are other similarly crude forms of aggregation. For instance, slime molds, which are single-celled organisms like amoebas, can group together to form larger masses that move in search of nourishment.
Overlap of Brain Regions in Imagination and Reality Perception
Naeblys/Alamy
How can we differentiate between what we perceive as real and what we imagine? Recent findings have uncovered brain pathways that may assist in this distinction, potentially enhancing treatments for hallucinations associated with conditions like Parkinson’s disease.
It’s already established that the brain regions activated during imagination closely resemble those engaged when perceiving real visual stimuli; however, the mechanism distinguishing them remains elusive. “What allows our brains to discern between these signals of imagination and reality?” asks Nadine Dijkstra from University College London.
To explore this, Dijkstra and her team observed 26 participants engaged in visual tasks while their brain activity was monitored via MRI scans. The tasks included displaying static grey blocks on the screen for 2 seconds, repeated over 100 times. Participants were prompted to imagine diagonal lines within each block, with half of the blocks containing actual diagonal lines.
Subsequently, participants rated the vividness of the lines they perceived on a scale of 1-4 and indicated whether the lines were real or imagined.
Through the analysis of brain activity, researchers found that when participants viewed the lines more vividly, the fusiform gyrus, a specific brain area, was more active, irrespective of the line’s actual presence.
“Prior research indicated that this area is engaged in both perception and imagination, but this study reveals its role in tracking the vividness of visual experiences,” notes Dijkstra.
Crucially, a spike in activity in the fusiform gyrus above a certain threshold led to increased activity in an associated area known as the previous island, causing participants to perceive the lines as real. “This additional area connects to the spindle-like moment, possibly aiding decision-making by processing and re-evaluating signals,” she adds.
While it’s likely that these brain regions are not the sole players in discerning reality from imagination, further investigation into these pathways could refine our understanding of treating visual hallucinations linked to disorders such as schizophrenia and Parkinson’s disease.
“Individuals experiencing visual hallucinations might exhibit heightened activity when visualizing their imagined scenarios, or the monitoring of their signals could be inadequate,” Dijkstra suggests.
“I believe this research could be pivotal for clinical cases,” says Adam Zeman, from the University of Exeter, UK. “However, distinguishing whether minor shifts in sensory experiences are driven by real-world events, discerning fully formed hallucinations, and determining the duration of beliefs remains a significant challenge,” he explains.
To address this knowledge gap, Dijkstra’s team is currently studying the brain pathways of individuals with Parkinson’s disease.
The ITER project is an experimental fusion power reactor
iter
Nuclear fusion holds the promise of nearly limitless energy, but achieving this goal requires the world to produce a significant amount of concentrated lithium fuel from the ground up.
“A major challenge is the concentration phase, where specific lithium types are concentrated,” explains Samuel Ward from Woodruff Scientific Ltd, a British firm dedicated to nuclear fusion. “There is currently no scalable solution capable of providing the fuel required for future fusion reactors.”
Lithium is essential for the most prevalent fusion technology being developed, which combines two forms of hydrogen to generate energy. Moreover, the rare lithium-6 isotope, constituting only 7.5% of naturally occurring lithium, is the most effective for sustaining the fusion process. Consequently, many fusion power projects depend on “enriched” lithium, increasing the lithium-6 content to over 50%, and occasionally as high as 90%.
Only one demonstration fusion plant is set to outpace experimental reactors by delivering net electricity to the grid. Ward and his team require between 10 to 100 tons of concentrated lithium to initiate and sustain operations. The emergence of a new demonstration plant is expected to heighten this demand.
The initial such plants are projected to be operational by around 2040, allowing time for the enhancement of lithium supplies. However, the enrichment strategy must accelerate—one report indicates that the current lithium-6 supply is nearly non-existent. The U.S. amassed stockpiles during the Cold War, producing approximately 442 tons of enriched lithium from 1952 to 1963 to support nuclear weapon fabrication. This process utilized toxic mercury, leading to environmental pollution that needed remediation for decades.
At present, low-purity lithium for fusion is transitioning from the scarce amounts of highly enriched lithium required for nuclear armaments, according to EGEMEN KOLEMEN at Princeton Plasma Physics Institute, part of the U.S. Department of Energy.
For early integration of power, researchers are advocating for a modernized, eco-friendly version of the enrichment process—yet it still relies on mercury. Last year, the German government allocated funds for a project aimed at advancing this form of lithium enrichment while improving cost-effectiveness. “We plan to launch the first concentration facility in Karlsruhe by 2028,” says Michael Frank, who is participating in this initiative at Argentum Vivum Solutions, a German consultancy.
“The only viable approach for supplying adequate lithium concentrate [in the] short and medium term relies on mercury-based methods,” asserts Thomas Giegalich from the Karlsruhe Institute of Technology in Germany, also a collaborator on the project. However, this type of method will not suffice for the extensive requirements of hundreds or thousands of commercial fusion reactors.
“There is broad recognition that mercury-dependent processes cannot sustainably support the widespread deployment of fusion energy,” states Adam Stein from the Breakthrough Research Institute, a research center based in California.
Various mercury-free concentration techniques are under exploration, but they are not yet suitable for immediate application. This is also the case with the UK’s Atomic Energy Agency, which is funding the development of a clean lithium enrichment process, including efficient lithium-6 separation through microorganisms.
“Given the current lack of demand and the need for further innovation, other techniques have yet to be demonstrated at a commercial level but must succeed,” says Stein.
Recent data from the National Oceanic and Atmospheric Administration at the University of California, San Diego, indicates that the Earth’s atmosphere contains millions, and potentially tens of millions, of carbon dioxide molecules.
For the first time ever, the global average concentration of carbon dioxide—a greenhouse gas emitted from burning fossil fuels—surpassed 430 parts per million (ppm) in May. These measurements represent a record high, with an increase of over 3 ppm from last year.
The findings suggest that efforts to curtail greenhouse gas emissions and reverse the growing accumulation of CO2 are insufficient.
“Another year, another record,” stated Ralph Keeling, a professor of climate science, marine chemistry, and geochemistry at the Scripps Institution of Oceanography in San Diego, California; he commented. “I am saddened.”
Carbon dioxide, like other greenhouse gases, traps heat from the sun and can persist in the atmosphere for centuries. High levels of these gases contribute to rising global temperatures and other adverse effects of climate change, including increased sea levels, polar ice melt, and more frequent extreme weather events.
Since the pre-industrial era, CO2 levels in the atmosphere have sharply risen, primarily due to human activities that release greenhouse gases.
Just a few decades ago, crossing the 400 ppm threshold seemed unimaginable. This means that for every million molecules of gas in the atmosphere, over 400 would be carbon dioxide. The planet reached this daunting milestone in 2013. Current warnings suggest that CO2 levels could approach 500 ppm within the next 30 years.
Human society is now in uncharted territory.
According to Keeling, the planet likely experienced such high atmospheric CO2 levels over 30 million years ago, during a time with very different climatic conditions.
He noted the remarkable speed at which CO2 levels are rising.
“It’s changing very quickly,” he told NBC News. “If humans had evolved in an environment with high CO2 levels, the absence of suitable habitats would have likely shaped our evolution. We could have adapted to that world, but instead, we’ve constructed society and civilization based on the climate of the past.”
CO2 levels are typically illustrated using the Keeling Curve, named in honor of Keeling’s father, Charles David Keeling, who began daily atmospheric CO2 measurements in 1958 from the Mauna Loa Observatory in Hawaii.
The Keeling Curve prominently displays the steep rise in CO2 since the Industrial Revolution, attributed to human-induced climate change.
Ralph Keeling and his colleagues at the Scripps Oceanographic Institute reported that the average atmospheric CO2 concentration for May was 430.2 ppm, while NOAA’s Global Monitoring Institute, which has been conducting separate daily measurements since 1974, noted an average of 430.5 ppm for the same month.
Monitoring atmospheric carbon dioxide levels is crucial for understanding how human activities impact the Earth’s climate. These measurements also serve as key indicators of the planet’s overall health.
“These measurements provide insight into the health of the entire system with just one data point,” Keeling explained. “We achieve a comprehensive view of the atmosphere through relatively simple measurement techniques.”
Is this the future in a world where the oceans are rising?
Deep R&D Ltd
The Bajau are indigenous marine people of Southeast Asia, often referred to as sea nomads. For millennia, they have thrived along coastlines, relying on foraging underwater without the aid of diving gear, holding their breath for astonishing durations. Yet, the early 21st century introduced multiple crises that jeopardized their way of life—industrial overfishing, pollution, coral bleaching diminished food sources, and rising sea levels consumed coastal dwellings.
In 2035, a Bajau community near Saba, North Borneo, initiated fundraising for a contemporary floating and underwater settlement. They collaborated with deep, a manufacturer of submarine habitats, to create interconnected rafts and underwater homes, developing business models that could be emulated by other maritime communities facing similar threats from rising seas. Revenue streams included extreme adventure tourism, scientific research facilities, and longevity clinics.
The first habitat comprised a network of platforms and rafts, with tunnels leading to underwater levels. While residents occupied surface structures, they increasingly utilized submerged areas for storage, sustenance, and sleep. This habitat was constructed using a 3D printing technique known as Wire arc additive manufacturing, which allowed the most effective pressure distribution in areas experiencing strain.
The deeper sections were maintained at both ambient water pressure and the corresponding atmospheric pressure from the surface. In modules situated less than 20 meters deep, occupants, referred to as Aquanauts, inhaled a unique gas mixture to prevent nitrogen narcosis. Those exiting deep modules required decompression when returning to normal atmospheric conditions. An advantage of these surrounding modules was the incorporation of a moon door, enabling Aquanauts to swim directly into the deep sea for leisure, research, and farming activities.
Undersea hotels catering to extreme tourism have surged in popularity. In the Galapagos, tourists reside in submerged hydroelectric hotels, exploring hot springs and observing some of the planet’s rarest life forms. Simultaneously, scientists harness these modules to investigate deep-sea ecosystems. Undersea mapping technologies have evolved, enabling researchers to explore vast ocean territories that were previously unreachable, fostering understanding and interactions with whales and other deep-sea creatures, leading to significant advancements in marine biology.
Aquanauts can swim directly into the deep sea for recreational, research, and agricultural activities
The Bajau have long been adapted to marine environments. With thousands of years at sea, they possess enlarged spleens that provide a higher quantity of oxygen-retaining red blood cells compared to typical humans. Some Bajau divers can spend five hours underwater, diving freely to depths of 70 meters without oxygen tanks, holding their breath for up to 15 minutes. After transitioning to seabed habitats, many Bajau began to leave behind surface living, opting instead to spend more time submerged, even resorting to gene editing to enhance their aquatic capabilities, including intentional eardrum puncturing to facilitate deeper dives, and utilizing surfactants in their lungs to aid their decompression, akin to adaptations found in diving marine mammals.

Numerous communities have established depth clinical treatments. Previous research has demonstrated that exposure to intermittent daily sessions of pressurized oxygen therapy can alleviate various medical conditions and age-related diseases. Hyperbaric oxygen therapy, for instance, has proven beneficial, leading individuals who underwent consistent high-pressure sessions to possess longer telomeres and enhanced clearance of senescent cells, both of which are linked to increased longevity. The deep habitat has attracted affluent seniors looking to extend their lives, simultaneously providing a lucrative income source.
The majority of marine communities have become self-sufficient, cultivating their own food through aquaculture of fish, mollusks, and seaweed, while also growing other crops on the surface. Energy sources include a combination of solar, wind, wave, and geothermal energy, tailored to local conditions. Some communities focus on tourism, whereas others specialize in carbon capture within medical facilities. A significant amount of seaweed is harvested, sunk into the ocean depths, and sold as carbon credits.
Living beneath the waves isn’t for everyone. Nonetheless, these habitats empower those most vulnerable to climate change, giving them the tools to redefine their livelihoods and lifestyles, even in the face of rising sea levels that threaten their homes.

Attention athletics fans, there’s an intriguing new competition to check out: Sperm Race.
It’s been reported that male birth rates are on the decline, with reduced sperm motility (movement speed) being a significant contributing factor. To raise awareness, a teenage founder has introduced sperm racing as a sport. As they say: “We’re creating the first racecourse for sperm: two competitors, two samples, one microscope finish line.”
Their site showcases “microscopic racetracks” that mimic reproductive systems, using “high-resolution cameras” to “track all microscopic movements.” They claim, “It’s all streamed live,” suggesting the phrase choice is deliberate, with the victor being “the first sperm to cross the finish line, confirmed via advanced imaging.”
The inaugural race on April 25th featured entries from two California universities. Readers may question why feedback on this topic emerged slowly. It’s due to a twist in the tale post-event.
Unfortunately for organizers, journalists like River Page, Reporter at Free Press, revealed that “the winner was predetermined. The ‘race’ was computer-generated.”
The issue is that microscopes can’t function that way. To have tracks long enough for sperm to swim competently, tracking them on camera is impractical. In film, a cameraman can follow Tom Cruise sprinting along the roof of a moving train. Yet, focusing a microscope can be challenging, even when the cells are nearly stationary.
The creators apparently ran a real race in a private setting, relying on computer-generated imagery to “depict” sperm racing for paying spectators.
This has led to speculation that a second round of the sperm race is improbable. I can’t help but recall how millions relish completely fabricated “sports entertainment” like wrestling, and outcomes in football often hinge on which teams have the wealthiest billionaires. Perhaps sperm racing could indeed be the next big sensation.
Water-Based Cooking
Feedback loves to explore the latest food trends, from cutting carbs to eating only lean meats, salt, and water! There’s even talk of “Air Protein,” which involves “microbial organisms that harness carbon dioxide.”
Essentially, water-based cooking means utilizing water for cooking whenever possible, in favor of oil. Think boiling, stewing, or steaming over stir-frying or roasting. This method reduces the formation of harmful advanced glycation end products (AGEs) found in the crispy bits of fried foods known to be linked to health complications. Hence, water-based cooking enthusiasts should steer clear of those.
Driving this trend is Michelle Davenport, a UCSF and NYU-trained nutrition scientist and the former founder of Digital Children’s Food Company. She educates followers on Instagram on how to manage metabolic health through water-based cooking inspired by family recipes.
Feedback perceives this might revolve around minor details, but it fits perfectly within wellness culture: if you’re not in peak health, it’s certainly your choice. Regardless, we find ourselves empathetic toward Elle from Bruski, who aptly stated: “It’s just soup. They’re making soup.”

As technology evolves, humans enhance their ability to teach skills to others
English Heritage/Heritage Images/Getty Images
Research into human evolution spanning 3 million years illustrates that advancements in communication and technology have occurred simultaneously. As early humans developed more sophisticated stone tools and various techniques, they also refined their abilities to communicate and educate the next generation on these new skills.
“There exists a scenario for the evolution of modes of cultural transmission throughout human history,” states Francesco Dalico, from the University of Bordeaux, France. “It seems there’s a co-evolution between the complexity of cultural traits and the complexity of their transmission methods.”
A defining characteristic of humanity is the progression toward more complex tools and behaviors. For instance, ancient humans crafted sharp stones for cutting or stabbing and affixed them to wooden shafts to create spears.
Crucially, the ability to instruct others in these skills is vital. For more intricate tasks like playing the violin or coding, extensive education and practice are typically necessary. However, in prehistoric times, the capacity for effective communication was limited, particularly before intricate languages emerged.
Furthermore, Ivan Colagè from the Pope University of the Holy Cross in Rome, along with D’Errico, investigated how the transmission of cultural information has evolved over the last 3.3 million years, aligning with changes in behavior and technology. They examined 103 cultural traits, such as specific types of stone tools, decorative items like beads, and burial customs. They documented the initial appearances of each trait in the archaeological record, indicating common practices.
The researchers assessed the complexity involved in learning each trait. Some simple tools, like stone hammers, require minimal instruction. “They don’t need much explanation,” D’Errico notes. In contrast, demonstrating the creation of more advanced tools is necessary, and the most intricate behaviors, such as deeply symbolic burials, demand explicit verbal explanations.
To analyze this, D’Errico and Colagè outlined three dimensions of learning: First, spatial proximity—can tasks be learned from a distance, or does one need to be physically present? Second, temporality—does one brief lesson suffice, or are multiple sessions necessary, perhaps emphasizing various steps? Third, the social aspect—who learns from whom?
They evaluated these traits and consulted a panel of 24 experts for assessment, whose consensus reinforced their findings. “I believe the conclusion is quite robust,” says D’Errico.
Recent studies indicate two significant shifts in cultural communication. The first occurred around 600,000 years ago when early humans began teaching one another, likely without relying on spoken language; gestures may have sufficed. This predates the emergence of our species, Homo sapiens, and aligns with the onset of hafting.
The second shift happened between 200,000 and 100,000 years ago, coinciding with the development of modern languages, which became essential for performing complex tasks like burials. “These actions involve many detailed steps, requiring explanation,” D’Errico explains.
“The relationship between cultural communication and cultural complexity is strong,” asserts Ceri Shipton from University College London. He emphasizes that while the timeline for language development remains uncertain, this new estimate provides a “reasonable timeframe.”
The identification of TO-6894B, an exoplanet roughly 86% the size of Jupiter orbiting the low-mass Redd star (0.2 solar masses), underscores the importance of enhancing our comprehension of the formation mechanisms of giant planets and their protoplanetary disc environments.

The TOI-6894 system is located approximately 73 parsecs (238 light years) away in the Leo constellation.
This planet was discovered through a comprehensive analysis of data from NASA’s Transiting Exoplanet Survey Satellite (TESS), aimed at locating giant planets around low-mass stars.
“I was thrilled by this discovery. My initial focus was on observing a low-mass red star with TESS, in search of a giant planet,” remarked Dr. Edward Bryant, an astronomer from the University of London.
“Then, utilizing observations from ESO’s Very Large Telescope (VLT), one of the most substantial telescopes globally, I identified TO-6894B, a giant planet orbiting the smallest known star with such a companion planet.”
“I never anticipated that a planet like TOI-6894B could exist around such a low-mass star.”
“This finding will serve as a foundational element in our understanding of the boundary conditions for giant planet formation.”
TOI-6894B is a low-density gas giant, with a radius slightly exceeding that of Saturn, which has only 50% of its mass.
The parent star is the lowest mass star yet found to host a massive planet, being just 60% of the mass of the next smallest star observed with such a planet.
“Most stars in our galaxy are actually small, and it was previously believed that they couldn’t support a gas giant,” stated Dr. Daniel Baylis, an astronomer at Warwick University.
“Therefore, the fact that this star has a giant planet significantly impacts our estimates of the total number of giant planets likely to exist in the galaxy.”
“This is a fascinating discovery. We still don’t completely understand why relatively few stars can form such large planets,” commented Dr. Vincent Van Eilen, an astronomer at the University of London.
“This drives one of our objectives to search for more exoplanets.”
“By exploring different planetary systems compared to our own solar system, we can evaluate our models and gain insights into how our solar system was formed.”
The prevailing theory of planetary formation is known as core accretion theory.
According to this theory, the cores of planets are initially formed by accreting material, and as the core grows, it attracts gases that eventually create its atmosphere.
Eventually, the core becomes sufficiently large to initiate the runaway gas accretion process, leading to the formation of a gas giant.
However, forming gas giants around low-mass stars presents challenges, as the gas and dust necessary for planetary formation in their protoplanetary discs is limited, hindering the formation of a sufficiently large core to kickstart this runaway process.
The existence of TOI-6894B indicates that this model may be insufficient and that alternative theories need to be considered.
“Considering TO-6894B’s mass, it might have been formed through an intermediate core-fault mechanism, whereby the protoplanet forms and accumulates gas steadily without orbiting, making it large enough to undergo runaway gas accretion,” Dr. Edward explained.
“Alternatively, it might have formed due to an unstable gravitational disk.”
“In certain cases, the disk surrounding the star can become unstable due to the gravitational forces it exerts on itself.”
“These disks may fragment as gas and dust collapse, leading to planet formation.”
However, the research team found that neither theory fully accounted for the formation of TOI-6894B based on the data available.
“Based on the stellar irradiation affecting TOI-6894B, we anticipate that its atmosphere is primarily influenced by methane chemistry, which is quite rare to identify.”
“The temperatures are low enough that atmospheric observations may even reveal the presence of ammonia.”
TOI-6894B might serve as a benchmark for methane-dominated atmospheric studies and an ideal laboratory for investigating planetary atmospheres containing carbon, nitrogen, and oxygen beyond our solar system.
Survey results will be featured in the journal Nature Astronomy.

Researchers from the Muon G-2 Experiment have unveiled their third measurement of the Muon magnetic anomaly. The conclusive results align with findings published in 2021 and 2023 but boast significantly improved precision at 127 parts per billion, surpassing the experimental goal for 140 people.

The Muon G-2 experiment investigates the wobble of a fundamental particle known as the Muon.
Muons resemble electrons but are roughly 200 times more massive. Like electrons, they exhibit quantum mechanical properties called spins, which can be interpreted as tiny internal magnets.
When subjected to an external magnetic field, these internal magnets wobble akin to the axis of a spinning top.
The precession speed of a magnetic field is influenced by the muon’s characteristics, captured numerically as the G-factor.
Theoretical physicists derive G-factors based on our current understanding of the universe’s fundamental mechanics, as outlined in the standard model of particle physics.
Nearly a century ago, G was anticipated to be 2; however, experimental measurements revealed minor deviations from this value, quantified as the Muon magnetic anomaly, Aμ, based on the formula (G-2)/2, giving the Muon G-2 experiment its name.
Muon magnetic anomalies encapsulate the effects of all standard model particles, enabling theoretical physicists to compute these contributions with remarkable precision.
Earlier measurements conducted at the Brookhaven National Laboratory during the 1990s and 2000s indicated potential discrepancies with the theoretical calculations of that era.
Disparities between experimental results and theoretical predictions could signal the existence of new physics.
In particular, physicists contemplated whether these discrepancies could stem from an undetected particle influencing the muon’s precession.
Consequently, physicists opted to enhance the Muon G-2 experiments to obtain more accurate measurements.
In 2013, Brookhaven’s magnetic storage ring was relocated from Long Island, New York, to Fermilab in Batavia, Illinois.
Following extensive upgrades and enhancements, the Fermilab Muon G-2 experiment launched on May 31, 2017.
Simultaneously, an international collaboration among theorists established the Muon G-2 theory initiative aimed at refining theoretical calculations.
In 2020, the Theoretical Initiative released updated and more precise standard model values informed by data from other experiments.
The differences between the experimental results continued to widen in 2021 as Fermilab announced the initial experimental results, corroborating Brookhaven’s findings with improved accuracy.
Simultaneously, new theoretical predictions emerged, relying significantly on computational capabilities.
This information closely aligned with experimental measurements and narrowed the existing discrepancies.
Recently, the Theoretical Initiative published a new set of predictions integrating results from various groups using novel calculation techniques.
This result remains in close agreement with experimental findings and diminishes the likelihood of new physics.
Nevertheless, theoretical endeavors will persist in addressing the disparities between data-driven and computational approaches.
The latest experimental values for the muon magnetic moment from Fermilab’s experiments are:
aμ =(g-2)/2 (Muon experiment) = 0.001 165 920 705
This final measurement is based on an analysis of data collected over the past three years, spanning 2021 to 2023, and is integrated with previously published datasets.
This has more than tripled the dataset size utilized in the second results from 2023, achieving the precision target set in 2012.
Moreover, it signifies the analysis of the highest quality data from the experiment.
As the second data collection run concluded, the Muon G-2 collaboration finalized adjustments and enhancements to the experiment, boosting muon beam quality and minimizing uncertainties.
“The extraordinary magnetic moment of the muon (G-2) is pivotal as it provides a sensitive test of the standard model of particle physics,” remarked Regina Lameika, associate director of high energy physics at the U.S. Department of Energy.
“This is an exhilarating result, and it’s fantastic to witness the experiment reach a definitive conclusion with precise measurements.”
“This highly anticipated outcome represents a remarkable achievement in accuracy and will hold the title of the most precise measurement of muon magnetic anomalies for the foreseeable future.”
“Despite recent theoretical challenges that have lessened the evidence for new physics in Muon G-2, this finding presents a robust benchmark for proposed extensions to the standard model of particle physics.”
“This is an incredibly exciting moment; not only did we meet our objectives, but we surpassed them, indicating that such precision measurements are challenging.”
“Thanks to Fermilab, the funding agencies, and the host lab, we accomplished our goals successfully.”
“For over a century, the G-2 has imparted crucial insights into the nature of reality,” stated Lawrence Gibbons, a professor at Cornell University.
“It’s thrilling to contribute accurate measurements that are likely to endure for a long time.”
“For decades, muon magnetic moments have served as a significant benchmark for the standard models,” noted Dr. Simon Kolody, a physicist at Argonne National Laboratory.
“The new experimental results illuminate this fundamental theory and establish a benchmark to guide new theoretical calculations.”
The advent of fire marks a significant point in human evolution, though scholars continue to debate its primary function. While cooking is frequently regarded as a key factor, researchers from Tel Aviv University propose that the protection of meat and fat from predators is more plausible. Homo Erectus lived during the Lower Paleolithic era, approximately 1.9 to 0.78 million years ago.
Miki Ben-Dor & Ran Barkai’s research highlights the nutritional value of meat and fat from large prey in the Lower Paleolithic, questioning the significance of culinary practices in shaping human dietary evolution and offering new insights into adaptations in Homo Erectus.
“The origins of fire usage is a ‘burning’ question among prehistoric researchers globally,” stated Professor Barkay, a co-author of the study.
“By around 400,000 years ago, it was widely accepted that fire was commonly used in domestic settings. I concur with the idea of meat roasting, as well as its use for lighting and heating.”
“However, there remains a debate concerning the past million years, with various theories put forth to explain early human interactions with fire.”
“This study aimed to approach this issue from a new angle.”
“For early humans, the use of fire wasn’t a given; most archaeological sites dated around 400,000 years ago show no signs of fire usage,” explained Dr. Miki Ben-Dor, lead author of the study from Tel Aviv University.
“However, in many early locations, there are clear indications of fire usage, even if there’s no evidence of burnt bones or roasted meat.”
“We see early humans—nearly Homo Erectus—utilizing fire sporadically for specific purposes rather than regularly.”
“Collecting fuel, igniting a fire, and maintaining it involved substantial effort, requiring a compelling energy-efficient reason.”
“We propose a new hypothesis for that motivation.”
In their research, the authors reviewed existing literature on all identified prehistoric sites between 1.8 million and 800,000 years ago where fire evidence has been found.
They identified nine sites globally, including Gesher Benot Ya’aqov and Evron Quarry in Israel, six sites in Africa, and one site in Spain.
The study also drew from ethnographic research on contemporary hunter-gatherer societies, relating their behaviors to ancient conditions.
“We examined the common features of these nine ancient sites and found they all contained a significant number of bones from large animals, mainly elephants, hippos, and rhinoceroses,” Dr. Ben-Dor noted.
“Previous research has shown these large animals were critical to early human diets, providing a substantial portion of their caloric needs.”
“For instance, the meat and fat from a single elephant can supply millions of calories, enough to sustain a group of 20 to 30 people for over a month.”
“Thus, hunting elephants and hippos was highly valuable—essentially a ‘bank’ of meat and fat that required protection and preservation, as it was sought after by predators and susceptible to decay.”
Through their analysis of findings and assessments of energetic benefits of preserving meat and fat, the researchers arrived at new conclusions that challenge previous theories. Early fires served dual purposes: first, to safeguard valuable resources from predators, and second, to facilitate smoking and prevent spoilage.
“This study introduces a novel perspective on the motivations behind early human fire use: the necessity to protect large game from other predators and the long-term preservation of substantial meat supplies,” Professor Barkay explained.
“Cooking may have occurred occasionally after fire was established for these protective purposes.”
“Such usage could elucidate evidence of fish roasting around 800,000 years ago found at Gesher Benot Ya’aqov.”
“Our approach aligns with evolving global theories that characterize major prehistoric trends as adaptations to hunting and consuming large animals, followed by a gradual shift to smaller prey exploitation.”
Survey results were published in the journal Nutrition Frontier.

A recent study conducted by physicists at the University of Oxford, Johns Hopkins, and the Institute of Astrophysics in Paris reveals a natural process involving a gravitational particle charger that utilizes free-falling particles from infinity, matter collisions from the most stable circular orbit of rotating black holes, and a gravitational particle charger that repeatedly cycles mass energy—excluding heavy particles. In essence, this describes the Super Collider.
The artist’s concept depicts an ultra-high massive black hole in the heart of the Milky Way galaxy known as Sagittarius A*. Image credits: NASA/ESA/CSA/RALF CRAWFORD, STSCI.
Particle corridors accelerate protons and other subatomic particles towards one another at nearly the speed of light, revealing the fundamental properties of matter.
A subtle energy flash occurs upon collision, with fragments potentially unveiling previously unknown particles that may serve as candidates for dark matter—a crucial, yet elusive, component of the universe that remains undetected by scientists.
Facilities like the Large Hadron Collider also contribute to advancements in areas such as the internet, cancer therapy, and high-performance computing.
“One of the great aspirations for a particle collider like the Large Hadron Collider is to produce dark matter particles, though we have yet to find any evidence,” commented Professor Joseph Silk, an astrophysicist from Johns Hopkins University and Oxford University.
“This is why there’s ongoing dialogue about the necessity of constructing a much more powerful version for the next generation of Super Collider.”
“However, we’ve been waiting for 40 years to invest $30 billion in building this Super Collider, allowing nature to give us a glimpse into the future with supermassive black holes.”
A black hole can rotate around its axis like a planet but possesses significantly greater strength due to its intense gravitational field.
Increasingly, scientists are discovering that massive black holes rapidly spinning at the center of galaxies release enormous explosions of plasma, potentially due to jets transporting energy from the spin and surrounding accretion disks.
These phenomena can yield similar results to those produced by engineered Super Colliders.
“If ultra-high energy black holes can generate these particles through high-energy proton collisions, we could receive signals on Earth. Some high-energy particles pass through the detectors rapidly,” Professor Silk explained.
“This indicates a new particle collider effect within one of the universe’s most mysterious entities, achieving energies unattainable by any accelerator on Earth.”
“We may observe something with a unique signature believed to indicate the presence of dark matter. While this is somewhat speculative, it remains a possibility.”
New research indicates that gas falling into a black hole can harness energy from its spin, resulting in more violent behavior than previously thought.
Near rapidly spinning black holes, these particles can collide in a coordinated manner.
While not identical, this process resembles the collisions created using strong magnetic fields, where particles are accelerated in a circular high-energy particle corridor.
“Some particles from these collisions are swallowed by the black hole and vanish forever,” stated Professor Silk.
“However, due to their energy and momentum, some particles emerge, achieving unprecedented high energies.”
“We have recognized the immense energy of these particle beams, rivaling what can be produced in a Super Collider.”
“Determining the limits of this energy is challenging, but these phenomena are certainly aligned with the energy levels of the latest Super Colliders we plan to construct, providing complementary results.”
To detect such high-energy particles, scientists can utilize observatories that are already monitoring supernovae, massive black hole eruptions, and other cosmic occurrences.
These include detectors like the IceCube Neutrino Observatory and the Kilometer Cube Neutrino Telescope in Antarctica.
The difference between a Super Collider and a black hole is their vast distances from one another. Nevertheless, these particles still reach us.
The team’s paper was published this week in the journal Physical Review Letters.

Characterized by pale greening, a timeline of ancient handwritten manuscripts—like the scroll of death—is vital for reconstructing the progression of ideas. However, there is an almost complete absence of manuscripts with dates. To address this challenge, an international team of researchers developed an AI-driven date prediction model named Enoch, inspired by biblical figures.

While some ancient manuscripts include dates, facilitating precise dating by archaeologists, many do not provide this information.
Researchers can estimate the age of certain undated manuscripts by analyzing the evolution of handwriting styles, but this requires a sufficient number of manuscripts with known dates for creating an accurate timeline.
In the recent study, the University of Groningen and Dr. Mladen Popović assessed the historical periods of manuscripts from various locations in contemporary Israel and the West Bank through radiocarbon dating and utilized machine learning to explore the handwriting styles of each document.
By merging these two datasets, they developed the Enoch program, which objectively estimates the approximate age range by comparing handwriting styles from other manuscripts in the area.
To validate the program, ancient handwriting specialists reviewed age estimates for 135 Ennochs from the Dead Sea Scrolls.
Experts concluded that around 79% of the AI-generated estimates were credible, while the remaining 21% were considered too old, too young, or uncertain.
Enoch has already aided researchers in uncovering new insights about these ancient manuscripts.
For instance, both Enoch and radiocarbon dating techniques estimated an older age for more Dead Sea scrolls compared to traditional handwriting analyses.
“While additional data and further investigation could enhance our understanding of the timeline, our findings offer novel perspectives on the creation periods of these documents,” the researchers stated.
“The Enoch tool serves as a gateway to an ancient world, akin to a time machine, permitting the exploration of biblical handwritten texts.
“It is thrilling to establish significant steps in developing new tools that can tackle the dating challenges of the Dead Sea Scrolls and examine other partially dated manuscript collections from history.”
“This achievement would not have been feasible without collaboration across diverse scientific fields and genuine teamwork.”
A paper detailing this study was published in the journal PLOS 1.

A device designed for facial and neck massage suggests it might enhance the brain’s waste removal system and alleviate symptoms associated with conditions like Alzheimer’s disease.
Cerebrospinal fluid (CSF) envelops the brain and inflates it before moving through a network of delicate tubes known as grinft blood vessels. Research on mice indicates that this fluid clears waste produced by brain cells, including proteins linked to diseases like Alzheimer’s and Parkinson’s, such as beta-amyloid.
This has prompted researchers to consider whether increasing CSF flow could promote brain health. However, they note that the grinft vessels, previously only discovered deep within the neck, are difficult to access. Gou Young Koh, from the Advanced Science and Technology Research Institute in Korea, remarks on this challenge.
Recently, Koh and his team identified a network of grinft vessels located just five millimeters beneath the skin on the faces and necks of mice and monkeys. They made this breakthrough by administering fluorescent dyes that label the CSF and imaging the subjects under anesthesia. “We utilized a different kind of anesthesia than was applied in earlier studies. The previous anesthetic blocked the visualization of vessels close to the skin,” Koh explains.
In their effort to determine if massaging these vessels could boost CSF flow, the researchers developed a device with small rods attached to a 1 cm cotton ball. They used it to gently stroke down the face and neck of a 2-year-old mouse for a few months, applying strokes for one minute on younger mice. “A gentle facial and neck massage can compress the liquid and enhance the CSF flow,” Koh states.
After 30 minutes of massage, CSF flow was observed to increase nearly threefold in the brains of the mice compared to their flow prior to the massage. Furthermore, this process seemed to reverse age-related decreases in CSF flow. “After stimulation, the CSF flow in older mice appeared comparable to that of younger mice [who hadn’t received the massage],” Koh elaborates.
In their unpublished findings, the team observed similar outcomes in monkeys. They also identified glymphetic blood vessels in human cadavers, implying that massage could stimulate CSF flow in humans, as suggested by Koh.
However, due to anatomical differences between mice, monkeys, and humans, further investigations are necessary to confirm this, remarks Vesa Kiviniemi from Uru University in Finland. “It’s a slightly different scenario.”
Moreover, it remains uncertain whether increased CSF flow can genuinely mitigate brain aging or offer protection against neurodegenerative conditions like Alzheimer’s. Stephen Prucks of the University of Bern in Switzerland stated that Koh’s team aims to investigate this with mice that exhibit Alzheimer-like traits.
Rivers like the Chuya in Russia can emit carbon dioxide and methane.

Globally, rivers are releasing ancient carbon into the atmosphere, revealing surprising insights for scientists and indicating that human impact on natural landscapes may be more severe than previously understood.
It is already established that rivers emit carbon dioxide and methane as part of the carbon cycle, a rapid gas exchange linked to the growth and decay of organisms, estimated to release around 2 Gigatonnes of carbon annually.
Researchers, including Josh Dean from the University of Bristol, explored the age of this carbon.
The team utilized radiocarbon dating to analyze carbon and methane released from over 700 river segments across 26 countries.
“When we compiled the available data, what we found was surprisingly significant. [Regarding the carbon released], these ancient stores may originate from much older reserves,” Dean states.
Ancient carbon is sequestered in geological formations such as rocks, peat bogs, and wetlands. The findings reveal that around one Gigatonne of this carbon is released annually via rivers, leading to the conclusion that ecosystems are currently removing one Gigatonne less carbon from the atmospheric balance than previously believed.
“This represents the first comprehensive assessment of river emissions on a global scale, which is quite remarkable,” remarks Taylor Maavara from the Cary Ecosystem Studies Institute in Millbrook, New York.
The pressing concern now is understanding the reasons behind the release of such ancient carbon. Factors might include climate change and human activities that alter natural landscapes. Dean observes that the carbon from rivers has appeared “aged” since the 1990s.
“Human activity may be accessing these long-term carbon reservoirs, which can lead to older carbon being released through these channels,” he explains.
For instance, rising temperatures due to climate change can result in carbon being released from thawing permafrost and increase the weathering rates of rocks. Additional factors such as peatland drainage and wetland desiccation could also play a role. Dean emphasizes the necessity for further research to ascertain the degree to which human activities contribute to this phenomenon and how carbon release varies over time.
“This is a critical area of research,” he asserts. “If we believe we are storing old carbon within these reservoirs, we’re mistaken; this understanding is crucial.” These insights carry significant implications for national climate strategies, particularly concerning reliance on natural ecosystems to mitigate ongoing emissions.
“This research raises intriguing questions about how and to what extent we can manage ancient carbon,” says Scott Teig from Oakland University in Rochester Hills, Michigan. He adds that tackling climate change is likely vital to prevent the release of CO2 and methane from these ancient reserves.
“That’s the million-dollar question,” he remarked. “I don’t have a very satisfactory answer.”
There are three distinct types of Sargassum found in the Caribbean and surrounding regions, buoyed by small air sacs, which makes their presence truly remarkable. According to Burns, scientists are currently observing various factors influencing its growth, which depend on sunlight, nutrients, and water temperature.
Experts also point to agricultural runoff, warmer waters, and alterations in wind, currents, and rainfall as factors that can have an impact.
Large mats of algae in the open ocean create what Burns refers to as a “healthy and thriving ecosystem,” home to species ranging from tiny shrimp to endangered sea turtles. However, Sargassum close to shore can wreak havoc.
It can block sunlight essential for coral reefs and seagrasses, and when the algae sink, they may suffocate these ecosystems. Once washed ashore, the organisms that inhabit the algae either perish or are scavenged by birds, according to Burns.
The massive piles of odorous seaweed pose a significant challenge for the Caribbean, especially since tourism is a vital economic driver for many small islands.
“It’s a hurdle, but it hasn’t impacted every corner of the Caribbean,” said Frank Comitto, a special advisor to the Caribbean Hotels and Tourism Association.
At a popular tourist destination in Punta Cana, Dominican Republic, officials have invested in barriers to keep Sargassum from reaching the beaches, he noted.
In St. Maarten’s Dutch Caribbean territory, teams equipped with backhoes were mobilized for an emergency cleanup after residents reported a strong ammonia and hydrogen sulfide odor.
“The smell is quite unpleasant,” Burns stated.
Meanwhile, in the French Caribbean, officials plan to quickly utilize storage barges and specialized vessels capable of collecting several tons of seaweed daily.
Sargassum “will harm our coastlines, hinder swimming, and create unbearable living conditions for local residents,” French Prime Minister François Beilou recently informed the press.
However, Comitto mentioned that employing such vessels is “very costly” and not widely accepted, while an alternative method (using heavy machinery) is labor-intensive.
“We must tread carefully, as sea turtle eggs might be affected,” he advised. “You can’t just go there and bulldoze everything away.”
As some Caribbean islands face financial challenges, most cleanup efforts fall to hotels, with certain guests receiving refunds and complimentary shuttles to unaffected beaches.
Each year, the volume of Sargassum increases at the end of spring, peaks during summer, and then starts to decline in late autumn or early winter, noted Burns.
The recent record levels remain relatively stationary. Experts are hopeful for more Sargassum in June.
Researchers might be on the brink of solving one of the most significant challenges in physics, potentially laying the groundwork for groundbreaking theories.
At present, two distinct theories—quantum mechanics and gravity—are employed to elucidate various facets of the universe. Numerous attempts have been made to fuse these theories into a cohesive framework, but a compelling unification remains elusive.
“Integrating gravity with quantum theory into a single framework is one of the primary objectives of contemporary theoretical physics,” states Dr. Mikko Partanen, the lead author of the recently published research in Report on Progress in Physics. He elaborates on this innovative approach in the context of BBC Science Focus, calling it “the holy grail of physics.”
The challenge of formulating a theory of “quantum gravity” arises from the fact that these two concepts operate on entirely different scales.
Quantum mechanics investigates the minutest scale of subatomic particles, leading to the development of standard models. These models link three fundamental forces: electromagnetic, strong (which binds protons and neutrons), and weak (responsible for radioactive decay).
The fourth fundamental force, gravity, is articulated by Albert Einstein’s general theory of relativity, which portrays gravity as a curvature of spacetime. Massive objects and high-energy entities distort spacetime, influencing surrounding objects and governing the domain of planets, stars, and galaxies. Yet, gravity seems resistant to aligning with quantum mechanics.
The Duality of Theories
A significant issue is that gravity is rooted in a “deterministic classical” framework, meaning the laws predict specific outcomes. For instance, if you drop a ball, gravity guarantees it will fall.
In contrast, quantum theory is inherently probabilistic, offering only the likelihood of an event rather than a definitive outcome.
“These are challenging to merge,” Partanen comments. “Attempts to apply quantum theory within gravitational contexts have yielded numerous nonsensical results.”
For example, when quantum physicists measure the electron’s mass, the equations spiral into infinity. Similarly, applying gravity in extreme conditions, like at the edge of a black hole, renders Einstein’s equations meaningless.
Even general relativity fails to explain phenomena within a black hole. -NASA
“While intriguing approaches like string theory [which substitutes particles with vibrating energy strings] exist, we currently lack unique, testable predictions to differentiate these theories from standard models or general relativity,” notes Partanen.
Instead of crafting an entirely new theory for unification, Partanen and his colleague, Professor Jukka Tulkki, approached gravity through the lens of quantum mechanics by reformulating the gravitational equations using fields.
Fields represent how quantum theory elucidates the variation of physical quantities over space and time. You may already be acquainted with electric and magnetic fields.
This novel perspective allowed them to replicate the principles of general relativity in a format that combines effortlessly with quantum mechanics.
Testing the Theories
A particularly promising aspect of this new theory is that it does not require the introduction of exotic new particles or altered physical laws, meaning physicists already possess the necessary tools for its verification.
According to him, this new theory generates equations that account for phenomena like the bending of light around massive galaxies and redshifts—the elongation of light’s wavelength as objects recede in the expanding universe.

While this validates the theory, it does not confirm its correctness.
To establish this, experiments must be conducted in extreme gravitational environments where general relativity falters.
If quantum gravity can make superior predictions in such scenarios, it would serve as a crucial step towards validating this new theory and suggesting that Einstein’s framework might be incomplete.
However, this is challenging due to the minimal differences between the two theories.
For instance, when observing how the sun’s mass bends light from a distant star, the predictive discrepancy is a mere 0.0001%. Current astronomical tools are insufficient for precise measurements.
Fortunately, larger celestial bodies can amplify these differences dramatically.
“For neutron stars with intense gravitational fields, relative differences can reach a few percent,” Partanen observes. While no observatory currently exists to make such observations, advancements in technology could soon enable this.
The theory remains in its nascent stages, with the team embarking on a mission to finalize mathematical proofs to ensure the theory avoids diverging into infinities or other complications.
If progress remains encouraging, they will then apply the theory to extreme situations, such as the singularity of a black hole.
“Our theory represents a novel endeavor to unify all four fundamental forces of nature within one coherent framework, and thorough investigation may unveil phenomena beyond our current understanding,” concludes Partanen.

Glue guns generally employ harmful oil-based adhesives

A by-product from the wood industry has been innovatively transformed into safe, reusable hot glue adhesives that could serve as an alternative to hazardous solvent-based adhesives.
Ziwen LV of Beijing University of Forestry, along with a colleague, developed an adhesive from xylan, a component of plant cell walls.
“Xylan acts as a binding agent for cellulose, yet isn’t traditionally considered a ‘glue’ on its own,” stated Nick Aldred, who wasn’t part of the research team at the University of Essex, UK. “This initiative aims to reactivate it as a viable adhesive.”
The LV team chemically modified xylan to create dai-alcohol xylan, utilizing sodium acid and sodium borate in the process.
The resultant adhesive, when extruded from the hot glue gun, boasts a bond strength of 30 megapascals, surpassing that of traditional epoxy resin adhesives. Additionally, it can be reused by remelting, maintaining its adhesive properties even after 10 cycles.
The team also constructed plywood held together with xylan adhesive and found its performance comparable to that of phenol-formaldehyde resin adhesives.
However, there’s a significant limitation: after being submerged in water for one hour, the adhesive melts and the layers disintegrate. The researchers didn’t respond to requests for comment from New Scientist.
Jonathan Wilker from Purdue University, Indiana, highlights the pressing need for sustainable alternatives to the petroleum-based adhesives presently in use.
“[The] combined performance [of the new glue] was quite impressive, especially on wood substrates,” remarked Wilker.
“If we can implement this on a larger scale within the plywood industry, it could be revolutionary,” emphasized Aldred. “Plywood remains one of the last consumer products still containing materials like phenols and formaldehyde, substances that were banned years ago in products such as cosmetics.”
The newest artificial intelligence models demonstrate a comprehension of the world akin to human understanding. Yet, their sensory limitations hinder their grasp of concepts like flowers and humor.
Qihui Xu from Ohio State and her team explored the understanding of nearly 4,500 words by both humans and large-scale language models (LLMs), covering terms such as “flowers,” “hooves,” “humorous,” and “swings.” Both human participants and AI models evaluated these words based on emotional arousal and physical interactions associated with various body parts.
The objective was to analyze how LLMs, such as OpenAI’s GPT-3.5 and GPT-4, along with Google’s Palm and Gemini, compared with human rankings. While both humans and AI exhibited similar concept maps for words unrelated to sensory interaction, substantial discrepancies arose when it involved physical sensations and actions.
For instance, AI models often suggested that flowers could be perceived through the torso, a notion that most people find peculiar, as they typically enjoy flowers visually or through scent.
The challenge lies in the fact that LLMs develop their understanding from a vast array of text sourced from the internet, which falls short in tackling sensual concepts. “They are fundamentally different from humans,” she explains.
Certain AI models have undergone training using visual data like images and videos alongside text. Researchers have noticed that these models yield results more closely aligned with human evaluations, enhancing the chances that future AI will bridge sensory understanding with human cognition.
“This illustrates that the advantages of multimodal training might surpass expectations. In reality, it seems that one plus one can yield two or more,” states Xu. “In terms of AI advancement, this underscores the significance of developing multimodal models and the necessity of embodying these models.”
Philip Feldman at the University of Maryland in Baltimore County suggests that simulating an AI with a robotic body, exposed to sensorimotor experiences, could greatly enhance its capabilities, but he cautions about the inherent risks of physical harm to others.
Preventing such dangers requires implementing safeguards in robotic actions or opting for softer robots to avoid causing injury during training, warns Feldman, although this approach has its downsides.
“This may distort their perception of the world,” Feldman remarks. “One lesson they might learn is that they can gently bounce objects. [In a real robot with mass] The humanoid robots might believe they can collide with one another at full speed. That could lead to serious issues.”
A potential new dwarf planet has been identified at the distant fringes of our solar system, taking approximately 25,000 years to complete one orbit around the Sun.
This celestial object, designated 2017, was discovered by a team from the Advanced Research Institute and Princeton University who were searching for a “Planet 9,” a hypothesized planet larger than Earth that is believed to orbit beyond Neptune. Some astronomers suspect that this elusive Ninth planet could shed light on the peculiar clustering of various objects and other oddities observed in the outer solar system.
While in pursuit of the elusive Planet Nine, researchers instead came across another resident of our cosmic neighborhood.
“It’s similar to the way Pluto was discovered,” remarked Sihao Cheng, a member of the Advanced Research Institute that spearheaded the research team. “This endeavor was a real adventure.”
If validated, the newly found dwarf planet could be what Chen refers to as Pluton’s “extreme cousin.” The findings were published on the Preprint site arXiv and have yet to undergo peer review.
Cheng and his colleagues estimate that 2017 measures approximately 435 miles in diameter.
Dwarf planets are categorized as celestial bodies orbiting the Sun that possess enough mass and gravity to be nearly round, yet unlike typical planets, they do not clear their orbital paths of asteroids and other objects.
Eritayan, a co-author of the study and a graduate student at Princeton University, noted that one fascinating characteristic of 2017 is its highly elongated orbit. At its most distant points from the Sun, it lies over 1,600 times farther than Earth does from the Sun.
The potential dwarf planets were discovered through a meticulous examination of a vast dataset from a Chilean telescope that was scanning the universe for signs of dark energy. By compiling observations over time, the researchers identified moving objects exhibiting clear patterns.
While 2017 may be one of the most distant known objects in the solar system, its discovery suggests that other dwarf planets may exist in that vast region of space.
“We used public data that had been available for some time,” explained Jiaxuan Li, a graduate student and co-author of the research at Princeton University. “It was just hiding in plain sight.”
Li mentioned that the object is currently located near the Sun, necessitating a wait of about a month for researchers to conduct follow-up observations using ground-based telescopes. They also hope to eventually study the object with the Hubble Space Telescope or the James Webb Space Telescope.
In the meantime, Chen stated he remains committed to the quest for Planet Nine. However, new findings may complicate long-held theories about the existence of such a planet.
The hypothesis surrounding Planet Nine suggests that planets several times Earth’s size in the outer solar system might clarify why certain groups of icy objects seem to have unusually clustered orbits.
“Under the influence of Planet Nine, any object lacking a specific orbital geometry would eventually become unstable and be expelled from the solar system,” Yang explained.
Despite 2017’s long orbit leading it away from clustered objects, Yang’s calculations indicate that its path will remain stable for the next billion years.
In essence, if Planet Nine existed, 2017 would not persist. Yet, Yang emphasized that further research is essential, and the discovery of a new dwarf planet candidate does not definitively rule out Planet Nine’s existence.
For one thing, the simulations currently utilize a single hypothetical location for Planet Nine, and scientists do not all agree on the locations of these planets.
Konstantin Batygin, a planetary science professor at the California Institute of Technology, first proposed the existence of Planet Nine in a 2016 study co-authored with Mike Brown from Caltech.
He remarked that the discoveries related to 2017 neither confirm nor deny the theory. Batygin noted that outer solar system objects that might demonstrate gravitational influences of Planet Nine must have their closest points of orbit remain sufficiently distant and not interact significantly with Neptune.
“Unfortunately, this object does not fall into that category,” Batygin told NBC News. “It’s in a chaotic orbit, so the implications are not significant, as it complicates the scenario.”
Batygin expressed excitement about the new research for providing additional context regarding how objects evolve in the outer solar system, praising the researchers’ efforts in mining public datasets as “heroic.”
Chen, however, remains optimistic about finding Planet Nine.
“The entire project commenced as a search for Planet Nine, and I’m still in that mindset,” he remarked. “This, however, is an enthralling tale of scientific discovery. Whether or not Planet Nine exists, the pursuit is a captivating venture.”
A recent study conducted by researchers at Harvard Chan Public Health indicates that caffeine and regular coffee consumption during middle age are modestly and positively linked to various aspects of healthy aging in women. However, no notable correlation was found with tea or caffeinated coffee, whereas increased cola intake was associated with healthy aging and a lower likelihood of related health issues.
Mahdavi et al. Our aim was to explore the relationship between caffeine intake in middle age and the chances of healthy aging in older women participating in nurse health studies. Image credit: Sci.News.
“While earlier studies have linked coffee to specific health outcomes, this research is the first to evaluate coffee’s impact on multiple aspects of aging over three decades,” stated Dr. Sarah Mahadhabi, a researcher at Harvard Chan School of Public Health and the University of Toronto.
“The findings indicate that coffee may uniquely support aging processes that foster both mental and physical well-being.”
“Our study boasts several significant strengths, including a substantial sample size and three decades of follow-up. Moreover, we assessed various elements of longevity and healthy aging, in conjunction with comprehensive data on nutrition and lifestyle habits collected every four years after the study began.”
The research encompassed 47,513 women from the Nurses Health Survey, utilizing dietary and health data gathered since 1984.
Researchers evaluated caffeine consumption using a validated food frequency questionnaire, focusing on major caffeine sources like coffee, tea, cola, and caffeinated coffee.
Healthy aging was characterized as living to age 70 and above, free from 11 major chronic diseases, preserving physical abilities, maintaining mental health, exhibiting no cognitive impairment, and having no memory complaints.
Following 30 years of monitoring, researchers assessed how the probability of healthy aging varied with each additional 80 mg of caffeine consumed daily by the participants.
They also examined specific beverage types, including coffee, tea, caffeinated coffee (per 8-ounce cup), and cola (per 12-ounce glass).
The preliminary analyses identified other factors that might influence healthy aging, such as body weight, smoking habits, alcohol consumption, physical activity levels, educational attainment, and protein intake.
By 2016, 3,706 women in the study met all criteria for being classified as healthy agers.
Women aged between 45-60 typically consumed an average of 315 mg of caffeine daily, with over 80% of that derived from regular coffee consumption.
For those in the Healthy Agers Group, each additional cup of coffee per day was linked to a 2% to 5% increased likelihood of aging well, up to about 5 small cups per day, or approximately 2.5 standard cups by today’s measurements.
Researchers discovered no significant correlation between the consumption of decaffeinated coffee or tea and an elevated likelihood of healthy aging.
Importantly, for each additional glass of soda with caffeine, the chances of healthy aging decreased by 20-26%, indicating that not all caffeine sources are beneficial.
“While these findings are preliminary, they suggest that small, consistent habits can profoundly influence long-term health,” Dr. Mahadhabi noted.
“Moderate coffee intake can provide a range of protective benefits when coupled with other healthy practices, such as regular exercise, a balanced diet, and avoiding smoking.”
“This study expands on previous evidence linking coffee consumption to healthy aging, but the benefits of coffee are relatively modest compared to the impact of an overall healthy lifestyle, warranting further investigation.”
The findings were presented at the Survey results on June 2nd during the Nutrition 2025 annual meeting hosted by the American Nutrition Association.

Paranthropus robustus is a well-documented species within the Hominin group that has yet to be associated with genetic evidence. This species thrived in what is now South Africa between 2 million and 1.2 million years ago. In a recent study, paleontologists extracted enamel protein sequences from a dental specimen, believed to be 2 million years old, discovered at the Swartkrans site in South Africa. The results indicate a greater diversity than previously recognized for Paranthropus robustus and support the potential existence of multiple species within the genus.
Advancements in ancient DNA (aDNA) sequencing have provided essential insights into the evolutionary connections among mid- to late Pleistocene hominins. However, our understanding of the earlier Pliocene-Pleistocene species, including Paranthropus robustus, remains limited.
This limitation is primarily due to the poor preservation of aDNA in African hominin fossils older than 20,000 years.
Paranthropus robustus has traditionally been regarded as a singular evolutionary line.
Yet, morphological overlaps between Paranthropus robustus and Australopithecus raise questions about their possible evolutionary links.
Moreover, variations in dental morphology suggest either an undiscovered diversity within Paranthropus robustus or the existence of multiple distinct species.
In this study, researchers from the University of Copenhagen, the University of Cape Town, and Dr. Paresa Madupe employed more durable ancient proteins to explore the variation within this ancient human species.
Four tooth enamel proteins were analyzed using high-resolution mass spectrometry and paleontological techniques, focusing on Paranthropus robustus fossils from the Swartkrans cave.
These specimens, dating from 2.2 to 1.8 million years ago, are among the earliest known hominins.
Molecular analysis of the protein sequences revealed significant variation at the molecular level among Paranthropus robustus individuals, including evidence from both male and female fossils, challenging the reliability of tooth size as a sole indicator of sexual dimorphism and suggesting that this variance cannot be attributed exclusively to sexual differences.
Notably, one individual appears to be genetically distinct from the others, highlighting considerable intraspecies variability within Paranthropus robustus.
The results align with recent morphological evidence, indicating previously unrecognized taxonomic diversity within the genus, including the proposed species Paranthropus capensis.
“Our study illustrates how paleobiological traits can assist in distinguishing sexual dimorphism from other forms of variation in the early Pleistocene human lineage in Africa,” the authors concluded.

In collaboration with the Chicago-Carnegie Hubble program, astronomers utilizing the NASA/ESA/CSA James Webb Space Telescope have conducted new measurements of the Hubble constant. The findings align with the prevailing Lambda Cold Dark Matter (λCDM) model without necessitating the introduction of additional new physics.

“Emerging evidence indicates that standard models of the cosmos remain robust,” stated Professor Wendy Friedman from the University of Chicago.
“While this doesn’t rule out potential inconsistencies with the model in the future, it currently appears consistent concerning the Hubble constant.”
Presently, there are two primary methods for calculating the rate of the universe’s expansion.
The first method involves measuring the residual light from the Big Bang, which still permeates the universe.
This radiation, referred to as the cosmic microwave background, provides astronomers with insights into the universe’s early conditions.
Professor Friedman and her colleagues focus on the second method, which assesses the current rate of expansion in our local astronomical context.
Ironically, this approach poses more challenges than retracing cosmic history due to the difficulty of accurately measuring distances.
Over the last fifty years, scientists have developed several techniques to measure relatively nearby distances.
One method relies on detecting the light from a specific category of stars at their brightest moment when they explode as supernovae at the end of their lifecycle.
By knowing the peak brightness of these supernovae, astronomers can gauge their apparent luminosity and determine the distance.
Further observations reveal how fast the galaxy that the supernova originated from is moving away from us.

Professor Friedman has advanced two additional techniques utilizing knowledge from other star types: giant red stars and carbon stars.
However, considerable adjustments are necessary before finalizing these distance measurements.
Astronomers first need to account for cosmic dust that dims the light coming from these distant stars within our galaxy.
It is also critical to verify and correct for any luminosity variations that may occur over time and space.
Lastly, correction for any subtle measurement errors from the instruments utilized is essential.
Fortunately, technological advancements, such as the launch of the more powerful Webb telescope in 2021, have enabled scientists to refine these measurements significantly.
“We have more than doubled the sample of galaxies used to calibrate supernovae,” Professor Friedman noted.
“Statistical enhancements are valuable and will greatly improve the findings.”
The latest calculations from the team, which incorporate data from both the Hubble and Webb telescopes, yield a value of 70.4 km per second, with a margin of error of 3% per megaparsec.
This brings the value into statistical alignment with recent measurements from cosmic microwave background observations at 67.4 km per megaparsec, with an accuracy of plus or minus 0.7%.
The Webb telescope, with four times the resolution of Hubble, allows for the identification of individual stars that were previously recorded as blurry groupings.
It also offers enhanced precision and is approximately ten times more sensitive, enabling the detection of significant objects.
“We’re truly witnessing how remarkable the Webb telescope is for accurately measuring distances to galaxies,” stated Dr. Taylor Hoyt, a researcher at Lawrence Berkeley Laboratory.
“Its infrared detectors can penetrate the dust that has historically impeded precise distance measurements, enabling much more accurate brightness assessments of stars.”
“Astrophysicists are striving to formulate a theory that might elucidate varying rates of expansion as the universe ages,” Professor Friedman remarked.
“There are over a thousand scholarly papers addressing this issue, and it proves to be exceptionally challenging.”
The team’s research paper was published on May 27th in the Astrophysical Journal.

Long-term conclusive results from US-based experiments have emerged. The latest release on Tuesday highlights a tiny particle behaving unexpectedly, which is still positive news for our understanding of Physics Laws.
“This experiment represents a remarkable achievement in precision,” noted Toba Holmes, an experimental physicist at the University of Tennessee Knoxville, who is not affiliated with the collaboration.
The enigmatic particles known as Muons are heavier than electrons. They exhibit a wobbling motion akin to a spinning top when subjected to a magnetic field, and scientists are scrutinizing this motion to determine its compliance with the well-established physics framework known as the standard model.
Findings from the 1960s and 1970s suggested everything was functioning as expected. However, investigations at Brookhaven National Laboratory in the late 1990s and early 2000s yielded unexpected results.
Decades later, an international coalition of scientists opted to revisit the experiment with enhanced accuracy. The team navigated Muons around magnetic, ring-shaped tracks akin to those used in the initial Brookhaven studies, and recorded the wobble signals at Fermilab National Accelerator Laboratory near Chicago.
The outcomes from the initial two sets published in 2021 and 2023 appear to affirm the odd behavior of Muons, encouraging theoretical physicists to reconsider the standard model alongside new metrics.
Recently, the team finalized the experiment and published Muon wobble measurements that align with their earlier findings, utilizing more than double the data collected in 2023.
Nevertheless, this does not finalize the fundamental understanding of what underpins the universe. As Muons travel along their paths, other researchers have devised methods to better harmonize standard models with observed behaviors, leveraging the power of supercomputers.
Further investigation is essential as researchers collaborate, and upcoming experiments will encourage future studies that assess Muon wobble. Scientists are also examining the latest Muon data for insights into other mysterious entities like dark matter.
“This measurement will serve as a benchmark for years to follow,” remarked Marco Incagli from the Italian National Institute of Nuclear Physics.
In their pursuit of Muons, scientists aim to unravel fundamental questions that have long intrigued physicists, as noted by Peter Winter from the Argonne National Laboratory.
“Isn’t it something we all wish to understand—how the universe operates?” Winter questioned.
In Sydney, Australia, Okkatoo has mastered the use of public water fountains by turning the handle, a feat not easy for birds. It appears they are imitating one another’s actions.
The Occato, or Kakatua Gallerita, engages in an intellectual competition, as some individuals have figured out how to open waste bins in eastern Sydney. In response, humans devise ways to keep these bins locked while continuing to find methods to open them.
Following reports of similar occurrences with Okkatoos using drinking fountains in western Sydney, Lucy Aplin from the Australian National University and her team temporarily marked 24 Occatos, accounting for a fifth of the local population. They documented the interactions at various drinking fountains, known as Bubblers in Australia.
Okkatoo using Sydney drinking fountain
Klump et al. 2025
During a 44-day observation, Cockatoos made 525 attempts to use a particularly popular fountain. Out of these, 105 attempts were made by 17 of the 24 marked birds. This indicates that about 70% of the more than 100 local birds attempted to use the fountain, according to researchers.
In their natural habitats, these birds typically drink from ponds or water stored in tree hollows near their roosts. However, Aplin notes they seem to prefer using the fountains instead, especially in the morning and evening, which are their regular drinking times before resting.
Researchers even observed more than 10 birds waiting for their turn at one bubbler, but the more dominant birds would often jump the queue.
Despite only 41% of the observed attempts being successful, the act of drinking from the fountain is certainly not a trivial task for these birds, according to Aplin.
“Birds must navigate their bodies through complicated movements,” she explains. “They often place one foot on the drinking fountain’s base and twist the handle with the other foot while leaning in to leverage their weight.”
She suspects that once an individual learns the technique, others follow suit by mimicking the actions.
“This serves as a clear example of culture—newly socially transmitted behaviors—which might surprise those who view culture as solely a human trait,” says Christina Zdenek from the University of Queensland, Australia. “Their innovative abilities in accessing new food and water sources are remarkable across the Tree of Life.”
Why are the Okkatoos doing this? Aplin posits that the water may taste superior to muddy pond water, or perhaps the bubbler offers a safer alternative from predators. It could also be a trend fueled by their thirst for innovation.
The private spacecraft is set to attempt a landing this week. Should the Japanese company ISPACE succeed on this attempt, it would mark a historic achievement as the first non-US enterprise to land on the moon, following a failed attempt in 2023.
ISPACE’s Resilience Lander embarked on its journey towards the moon on January 15th. It launched with the assistance of a SpaceX rocket and Firefly Aerospace’s Blue Ghost Lander. While Blue Ghost made a successful landing on March 2nd, Resilience traveled a longer path, traversing deeper into space before entering lunar orbit on May 6th. This intricate route was essential for landing in the hard-to-reach northern plains of Mare Frigoris, which had been uncharted by previous lunar missions.
If the probe executes its landing operations successfully, it will commence its landing sequence on June 5th at approximately 7:20 PM BST, with a landing in Mare Frigoris scheduled an hour later. The landing attempt will be broadcast live on ISPACE’s YouTube channel.
The lander is outfitted with six diverse experiments, including a device capable of splitting moisture into hydrogen and oxygen for usable resources, a module for producing food from algae, and a radiation monitor for deep space studies. Additionally, it will deploy a 5-kilogram rover named Tenalious, tasked with exploring the lunar surface and capturing images during its anticipated two-week mission.
This marks ISPACE’s second attempt at a lunar landing, following the initial Hakuto-R spacecraft, which lost communication and crash-landed on the moon. The company asserts that it has enhanced Resilience with improved sensors leveraging data gathered from the initial mission, yet challenges remain, particularly in slowing the spacecraft from several hundred kilometers per hour to a complete stop in just three minutes. Should ISPACE choose to abort the landing on June 5th, there are three alternate landing sites and dates prepared as contingencies.
Egg mass containing invasive adult termites Coptotermes gestroi
T Chouvenc, UF/IFAS
Florida’s latest termites offer a unique two-for-one deal, but there’s no celebration for them. Two species of invasive wood-eating insects have interbred, resulting in hybrid colonies that can produce extraordinarily resilient termites, posing a threat to both buildings and forests.
The results are “intriguing and unexpected,” notes Edouard Duquesne, a researcher at the Free University of Brussels, who was not part of the study. “The viable hybrids of these species could have a significantly broad geographic range, leading to highly invasive termites capable of causing severe damage.”
Since 2010, termite infestations have resulted in $40 billion in annual losses, with around 80% attributed to the Coptotermes genus. The Formosan subterranean termites (Coptotermes formosanus) have invaded many warm temperate regions of the Northern Hemisphere, while their Asian counterpart, Coptotermes gestroi, has expanded from Southeast Asia to tropical areas worldwide. Since the late 1990s, both species have overlapped in southern Florida, according to Thomas Chouvenc at the University of Florida.
In 2015, Chouvenc and his team demonstrated that these two species could produce hybrid offspring in controlled environments. By 2021, Chouvenc discovered alates—winged termites that establish new colonies—with characteristics merging those of the Formosan and the smaller, darker Asian species. These hybrids were identified in Fort Lauderdale, Florida, and were confirmed through genetic testing. A hybrid nest was also found in a local park adjacent to the marina.
In 2024, the existence of wild hybrids was validated by Taiwanese researchers, confirming that these species have coexisted for a century in southern Florida.
“It’s only a matter of time before we see hybridization and the establishment of hybrid populations wherever these two species coexist,” warns Chouvenc.
Researchers have also observed that first-generation hybrid females can mate with males from either parent species. Chouvenc expresses concern that gene flow between the species could lead to the emergence of a termite population that thrives in a wider range of environmental conditions, including temperature variations. The proximity of these termites to a busy port heightens the risk that such hybrids could be transported globally.
“We [humans] didn’t pay enough attention, and as a result, we’ve allowed these termites to spread,” Chouvenc added.
Paleontologists have discovered peptide markers for three extinct Australian megafauna. This breakthrough facilitates research on creatures such as hippo-sized wombats, colossal kangaroos, and marsupials with enormous claws, aiding our understanding of the series of enigmatic extinctions that took place 50,000 years ago and the potential role of humans in these events.
“The geographical distribution and extinction timeline of Australia’s megafauna, along with their interaction with early modern humans, are subjects of intense debate,” commented Professor Katerina Dorca from the University of Vienna.
“The limited fossil finds at various paleontological sites across Australia complicate the testing of hypotheses regarding the extinction of these animals,” added Dr. Kali Peters, Ph.D., of the University of Algarbe.
“Using ZooMS (Zoo departments by mass spectrometry) can aid in increasing the number of identified megafauna fossils, provided that collagen peptide markers for these species are accessible.”
Through the analysis of peptides in collagen samples, researchers can differentiate between various animal species, occasionally even distinguishing among different variants.
Collagen proves to be more resilient than DNA, making this method effective in tropical conditions where DNA may not endure.
However, most reference markers originate from Eurasian species that are not found elsewhere.
This study aims to develop new reference markers tailored for Australian contexts, enhancing the understanding gleaned from the fragmented fossil records of Australia.
“Proteins tend to endure better over extensive time periods and in harsh environments compared to DNA,” noted Dr. Peters.
“Thus, in studying megafauna extinction, proteins might still be preserved even in the absence of DNA.”
The research focused on three species crucial for comprehending megafauna extinction: Zygomaturus trilobus, Palorchestes Azael, and Protemnodon Mamkurra.
Zygomaturus trilobus and Palorchestes Azael belong to a lineage of animals that vanished entirely during the late Quaternary period, while Protemnodon Mamkurra survived long enough to likely coexist with humans arriving in Tasmania.
Scientists previously dated fossilized bones from one species back over 43,000 years.
“Zygomaturus trilobus was among the largest marsupials that ever lived, appearing much like a hippo-sized wombat,” said Professor Douka.
“Protemnodon Mamkurra was a massive, sluggish kangaroo that might have occasionally walked on all fours.”
“Palorchestes Azael was a uniquely shaped marsupial with a distinctive nose and long tongue, powerful forelimbs, and a skull equipped with large claws.”
“If ancient continents connected early modern humans to what we now know as Australia, New Guinea, and Tasmania 55,000 years ago, they would have encountered astonishing creatures.”
The researchers eliminated contaminants and compared peptide markers using reference markers.
The collagen in all three samples was well-preserved, enabling the identification of appropriate peptide markers for each species.
With these markers, paleontologists successfully differentiated Protemnodon from five living genera and one extinct genus of kangaroo.
They could also differentiate Zygomaturus and Palorchestes as these two species couldn’t be distinguished from other large extinct marsupials.
This is common in ZooMS, given that collagen changes accumulate slowly over millions of years of evolution.
Unless further studies enhance specificity, these markers are most effective at identifying bones at the genus level rather than the species level.
Nevertheless, Zoom’s ability to distinguish genera from temperate regions presents opportunities to try and identify bones from tropical regions, where closely related species may feature similar or identical peptide markers, since DNA preservation is rare in these environments.
“The introduction of newly developed collagen peptide markers allows us to identify a multitude of megafauna remains in Australia’s paleontological collections,” stated Dr. Peters.
“Yet, many more species still require characterization through collagen peptide markers.”
“For instance, Diprotodon, the largest marsupial genus ever known, and Thylacoleo, the largest marsupial predator.”
The team’s findings will be published in the journal Frontiers in Mammal Science.

The Milky Way galaxy is often believed to be on a collision path with the neighboring Andromeda galaxy. This merger, anticipated roughly 5 billion years in the future, is expected to create a new elliptical galaxy. However, recent studies indicate that the likelihood of such a catastrophic event may be less than previously assumed.
These images depict three encounter scenarios between the Milky Way galaxy and the neighboring Andromeda galaxy. Top left: Messier 81 and Messier82. TopRight: NGC6786. BOTTOM: NGC 520. Image credits: NASA/ESA/STSCI/DSS/Till Sawala, Helsinki University/Joseph Depasquale, STSCI.
The Milky Way navigates through space, its trajectory affected by the gravitational forces from nearby galaxies, including Andromeda, Triangulum, and the Large Magellanic Cloud.
Consequently, prior studies have proposed for over a decade that the Milky Way is likely to collide with Andromeda, forming a new elliptical galaxy referred to as Milkomeda in about 5 billion years.
Dr. Thiru Sawara, an astronomer at the University of Helsinki, stated:
In their latest research, Dr. Sawara and colleagues utilized updated data from the ESA Gaia satellite and the NASA/ESA Hubble Space Telescope to model the Milky Way’s movement through space over the next 10 billion years, while also refining estimates of the masses of local galaxies.
They discovered that there is about a 50% chance that no collision will occur between the Milky Way and Andromeda during this time frame.
The authors suggest that previous analyses overlooked certain calculations and uncertainties, including the gravitational influence of the Large Magellanic Cloud (a smaller galaxy orbiting the Milky Way).
They also propose that a merger with the Magellanic Clouds is nearly certain within the next two billion years, prior to any potential interaction with Andromeda.
“Even with the latest and most precise observational data at hand, the future of local galaxy groups remains uncertain,” Dr. Sawara remarked.
“Interestingly, there are roughly equal probabilities of widely discussed merger scenarios or, conversely, scenarios where the Milky Way and Andromeda remain unaffected.”
The team’s findings will be featured this week in the journal Nature Astronomy.

Regularly incorporating chickpeas into your diet can lead to a notable reduction in cholesterol levels. Discover more at the Nutrition 2025 Meeting in Orlando.
A 12-week research study by the Illinois Institute of Technology explored the impact of consuming one glass of chickpeas or black beans daily with a group of 72 pre-diabetic adults.
Participants were randomly assigned to consume chickpeas, black beans, or rice (as a control) along with their usual meals. Blood samples were taken at the beginning, middle, and conclusion of the study to monitor alterations in cholesterol, inflammation, and blood glucose levels.
The findings indicated that total cholesterol levels dropped significantly from an average of 200.4 to 185.8 milligrams per deciliter after 12 weeks of daily chickpea intake.
Among the legumes studied, only chickpeas were linked to lower cholesterol. “No significant changes in cholesterol were detected with black bean consumption,” stated Morgan Smith, who spoke to doctoral candidates from the Illinois Institute of Technology presenting their research at the conference. BBC Science Focus.
Additionally, chickpeas appeared to reduce inflammation in the short term. “By the six-week mark of chickpea consumption, we noted a significant decline in highly sensitive C-reactive protein (HS-CRP),” Smith remarked. This protein serves as a marker for inflammation in the body.
“Nevertheless, these results diminished by week 12. Although HS-CRP remained lower at week 12 compared to the baseline, the distinctions were no longer statistically significant,” she explained.
Conversely, while black beans did reduce inflammation, they did not impact cholesterol levels.
These results imply that chickpeas and black beans may provide varied health advantages due to their unique nutritional compositions.

“We are currently investigating this, particularly concerning the bioactive components that set apart black beans from chickpeas,” Smith added. “We are analyzing the (poly)phenol content of both the intervention and the corresponding metabolite profile in the blood.”
Smith noted that chickpeas and black beans were selected for their “richness in dietary fiber, plant-based proteins, and bioactive compounds,” and for their convenience as canned options.
“Participants were in a free-living state and simply asked to integrate canned black beans or chickpeas into their regular diet without any specific preparation guidelines,” she stated.
While the study did not yield changes in blood glucose levels, researchers are still examining data related to glucose regulation and plan to explore how legumes influence gut microbiota.
“We are particularly focused on identifying changes in microbial metabolites, like short-chain fatty acids, and how these alterations enhance metabolic health outcomes,” Smith remarked.
“Ultimately, our aim is to deepen our understanding of the connections between diet, microbiome, and chronic disease prevention.”
The complete findings of this study are yet to be published in peer-reviewed journals.

San Juan, Puerto Rico – Enveloped in a significant amount of dust clouds from the Sahara Desert, the Caribbean is headed towards the US on Monday for one of the year’s most noteworthy events.
These clouds have expanded from Jamaica, stretching approximately 2,000 miles (3,200 kilometers) past Barbados in the Eastern Caribbean, and about 750 miles (1,200 kilometers) from the Turks and Caicos Islands down to Trinidad and Tobago.
“It’s quite remarkable,” noted Alex Dasilva, a hurricane expert at Accuweather.
The hazy skies have triggered sneezing, coughing, and watery eyes throughout the Caribbean. Local meteorologists are advising individuals with allergies, asthma, or other respiratory issues to stay indoors or wear face masks when outside.
Idiana Zayas, a forecaster at the National Weather Service in San Juan, Puerto Rico, reported elevated dust levels.
As per the National Oceanic and Atmospheric Administration, an aerosol’s optical depth quantifies how many particles obstruct sunlight from reaching the ground.
The plume is anticipated to reach Florida, Louisiana, Alabama, and Mississippi later this week and over the weekend, Dasilva mentioned.
However, he indicated that plumes often lose much of their density in the Eastern Caribbean.
“These islands typically face higher concentrations that can partially block sunlight, leading to more noticeable effects,” he remarked.
The dry, dusty air known as the Saharan air layer originates from the African Sahara Desert and travels westward from around April to October, according to NOAA. It also hinders the formation of tropical waves during the Atlantic hurricane season, which runs from June 1 to November 30.
June and July generally see the highest average dust concentrations, with plumes moving between 5,000 and 20,000 feet above ground, Dasilva pointed out.
In June 2020, record levels of Sahara dust filled the Caribbean. The scale and density of the plume were unprecedented in half a century, prompting forecasters to label it the “Godzilla Dust Cloud.”
The Cascadia subduction zone, a vast fault line extending from Northern California to British Columbia, has remained unsettlingly silent for 300 years. Should it finally rupture, a substantial earthquake is anticipated to shake the Pacific Northwest for several minutes.
Even more alarming, the resulting tsunami could generate waves reaching up to 100 feet (30 meters), wreaking havoc along the coast.
New research published in Proceedings of the National Academy of Sciences indicates that this event would only mark the onset of Cascadia’s cataclysm.
As if waves equivalent in size to those of the 2004 Boxing Day tsunami weren’t frightening enough, the latest analysis reveals land along the coast could subside by more than 2.5 meters (8 feet) almost instantaneously.
“We often discuss climate-induced sea level rises at a rate of 3-4 millimeters annually,” noted Professor Tina Dura, the lead author of the study, in an interview with BBC Science Focus. “But here, we could witness a 2-meter sea level rise in just a few minutes. Why aren’t we talking about that more?”
What Happens When Cascadia Erupts?
The Cascadia subduction zone represents the boundary where the oceanic Juan de Fuca plate descends beneath the North American plate. However, these tectonic plates tend to get stuck rather than moving freely. When they finally lock in place, immense pressure builds over centuries.
Once this pressure is released, it results in a formidable earthquake.
Cascadia is capable of producing earthquakes reaching magnitudes of 9.0 or higher, historically experienced once every 450-500 years. The last event occurred on January 26, 1700, with estimates suggesting its magnitude was likely between 8.7 and 9.2.
According to the US National Earthquake Hazard Model, there is a 15% chance of experiencing earthquakes of magnitude 8.0 or greater in this zone over the next 50 years.
Planning exercises conducted by the Federal Emergency Management Agency in 2022 predicted that these tremors could directly result in 5,800 fatalities, with an additional 8,000 lives lost to the tsunami.
Over 100,000 individuals could be injured, and more than 618,000 buildings could be damaged or destroyed, impacting over 2,000 schools and 100 critical facilities. The estimated economic impact: $134 billion.
“This will definitely be a catastrophic event for the United States,” Dura stated.

Aftershocks That Will Last for Decades
While the earthquake and tsunami will be devastating on their own, Dura and her colleagues warn that the long-term consequences could be equally destructive.
By integrating historical records of past Cascadia earthquakes with geological data from numerical models, the researchers assessed how coastal landscapes may be altered due to subsidence from the sudden sinking of land during an earthquake.
If a Cascadia earthquake were to occur today, land at 24 estuaries stretching from southern Washington to northern California could drop anywhere from 0.23 to 2.67 meters (0.76 to 8.76 feet) in minutes.
This could significantly expand the 100-year flood plain by 300 square kilometers (115 square miles), meaning more homes, roads, and infrastructure would fall into at-risk areas. In a severe subsidence scenario, flood exposure could more than double.
“It’s a dual threat,” Dura explained. “The tsunami will be catastrophic, but we also know that some locations will face extreme impacts, while others will experience serious repercussions due to the geographic layout of the coast.”

In 1700, the infrastructure suffered minimal damage. Today, the region is filled with critical systems that remain vulnerable to inundation. These include five airports, 18 emergency facilities (such as schools, hospitals, fire stations), eight wastewater treatment plants, one current, and 57 potential contamination sources like gas stations and chemical storages.
Submerged roads and flooded emergency hubs could severely impede recovery, while saltwater intrusion could damage farmland, resulting in long-term economic repercussions.
Furthermore, natural flood defenses like intertidal wetlands could be inundated or eroded, weakening protection against future storm surges. Rising tidal ranges could compound high-water flooding and may exacerbate the erosion of sandy coastlines.
“Once the tsunami hits and eventually recedes, the land will remain at a lower level,” Dura noted. “The flood plain footprint will evolve over decades, and even centuries.”
The Sooner It Hits, The Better
While the occurrence of an earthquake is inherently negative, the longer Cascadia remains quiet, the worse the ultimate disaster may be.
Researchers simulated what would occur if an earthquake were to strike in 2100 instead of today. With climate change, rising sea levels could exacerbate the consequences.
The global average sea level has already seen an increase of 21-24 cm (8-9 inches) since 1880, as reported by the National Oceanic and Atmospheric Administration. Projections suggest an increase of at least 20 cm (2 feet) by 2100.
However, the situation in Cascadia is somewhat complex. As the Juan de Fuca plate slides beneath the North American plates, the land on the continent is gradually uplifted, temporarily masking the implications of global sea level rise.
This slow upward thrust won’t last indefinitely. Eventually, climate change will catch up, leading to a rise in sea levels in the Pacific Northwest on par with other areas. Consequently, the two challenges—tectonic and climatic—are converging.
“You can imagine that when the land subsides during the next earthquake, you suddenly have to contend with centuries of comparable sea level rise,” Dura remarked.
By 2100, even without earthquakes, researchers estimate that flood plains could expand by 100 square kilometers (40 square miles). This, combined with subsidence from a potential earthquake, could triple flood exposure compared to today, resulting in a flood plain enlargement of up to 370 square kilometers (145 square miles).
How Can You Prepare?
What steps can communities take to prepare for this complex threat that combines earthquakes, tsunamis, subsidence, and sea level rise?
Dura admitted that there is no straightforward solution.
“Cascadia presents a unique challenge due to its prolonged quietude,” she said. “It’s tough to keep residents informed about the risks without inciting undue panic. How do you prepare without instilling fear?”
As an initial measure, Dura’s team suggests incorporating their findings into flood hazard and tsunami maps and collaborating across agencies to enhance preparedness.
Key actions include identifying critical infrastructure in future flood zones, planning for relocation or adaptation, promoting nature-based solutions by raising public awareness, restoring wetlands, and carefully considering new developments in high-risk areas.
Is all hope lost? Dura insists that time is of the essence.
“There are certainly individuals actively working on this. I don’t want to undermine their efforts,” she said. “But we need more people engaged in the issue. Perhaps we lack adequate resources, funding, or personnel, but collective efforts are being made, and significant new research is emerging.”

New research suggests that consuming sweet beverages poses a greater risk of type 2 diabetes compared to eating foods that contain sugar.
The study from Brigham Young University (BYU) in the US found that sugary drinks, such as sodas and fruit juices, are linked to an increased likelihood of developing the disease, whereas no similar connection was found with sugar intake from solid foods.
Dr. Karen Dela Corte, the lead author of the study and a professor of nutrition sciences at BYU, stated that the findings highlight why consuming sugar in the form of beverages like soda and juice is more detrimental to health than ingesting it through food.
Researchers analyzed data from 29 studies involving over half a million individuals across Europe, the Americas, Asia, and Oceania to identify which sources of sugar are most closely associated with the onset of type 2 diabetes.
The analysis revealed that a 340ml (12oz) serving of sugary drinks (including soft drinks, energy drinks, and sports drinks) increases the risk of type 2 diabetes by 25%.
Fruit juices, such as pure fruit juice and various juice drinks, exhibited similar effects, even when consumed in moderation. An additional 226ml (8 oz) serving per day raised the risk by 5%.
These risks are relative; for instance, if an individual has a baseline risk of 10% for developing type 2 diabetes, consuming four sodas daily could elevate that risk to around 20%.
Conversely, dietary sugars derived from fruit, table sugar, and general sugar content were not linked to a higher risk of type 2 diabetes and may even be associated with a lower risk in some cases.

As this study is observational, it cannot definitively establish a direct cause-and-effect relationship between sugary drinks and type 2 diabetes. It’s possible that individuals who consume more sugary beverages are more likely to develop the condition.
The researchers adjusted their analyses to account for calorie intake, obesity, and other lifestyle factors, allowing them to isolate the impact of sugar itself instead of focusing on overall caloric consumption.
Nevertheless, Dela Corte emphasized that the findings highlight the necessity for more stringent nutritional guidelines regarding liquid sugars, including fruit juices, in relation to health. “Future dietary recommendations may need to differentiate the health impacts of sugar based on its source and form,” she said.
