Scientists discovered that more muscle and less hidden abdominal fat are linked to a younger biological brain age. Deep visceral fat appeared to accelerate brain aging, while muscle mass offered a protective ...
Personalized algorithms may quietly sabotage how people learn, nudging them into narrow tunnels of information even when they start with zero prior knowledge. In the study, participants using algorithm-curated clues explored less, absorbed a ...
Researchers studying Yellowstone’s depths discovered that small earthquakes can recharge underground microbial life. The quakes exposed new rock and fluids, creating bursts of chemical energy that microbes can use. Both the water chemistry and the ...
A horned native bee dubbed Megachile lucifer has been discovered in Western Australia’s Goldfields. Identified while surveying a rare wildflower, the species stood out with its unusual “devilish” facial horns. DNA testing confirmed it was ...
Using a precisely aligned pair of laser beams, scientists can now hold a single aerosol particle in place and monitor how it charges up. The particle’s glow signals each step in its changing electrical state, revealing how electrons are kicked ...
Moss spores survived an extended stay on the outside of the ISS and remained capable of germinating once back on Earth. Their resilience to vacuum, extreme temperatures, and UV radiation surprised the researchers who expected them to perish. The ...
Sargassum seaweed is creating major new obstacles for sea turtle hatchlings, drastically slowing their crawl to the ocean and increasing their risk from predators and heat. Despite the physical challenge, their energy stores stay stable, suggesting ...
UC Davis researchers engineered wheat that encourages soil bacteria to convert atmospheric nitrogen into plant-usable fertilizer. By boosting a natural compound in the plant, the wheat triggers bacteria to form biofilms that enable nitrogen ...
A massive long-term study shows that Mediterranean and plant-based diets can help prevent chronic constipation in aging adults. Surprisingly, the benefits weren’t explained by fiber alone. Western and inflammatory diets raised constipation risk, ...
Ultra-processed foods are rapidly becoming a global dietary staple, and new research links them to worsening health outcomes around the world. Scientists say only bold, coordinated policy action can counter corporate influence and shift food systems ...
Researchers have uncovered a surprising new role for the HSL protein: beyond breaking down fat, it also works inside the nucleus of fat cells to keep them functioning properly. When HSL is missing, fat tissue doesn’t expand as expected— instead, ...
Monk parakeets ease into new friendships, slowly approaching strangers to avoid aggressive encounters. Researchers watched how birds shared space, groomed each other, and escalated to deeper social bonds over time. The results show a clear pattern ...

Europe is investing in a coordinated effort to develop high-power optical vortex technologies and train new specialists in the field. The HiPOVor network unites academia and industry to advance ...

Participants lost more weight on a low-fat vegan diet than on the Mediterranean diet, largely due to eliminating animal foods and reducing oils and nuts. Increased intake of plant foods, even ...

Researchers discovered that copper oxide catalysts form metallic copper mid-reaction, triggering a dramatic boost in ammonia output. The insight offers a roadmap for designing cleaner, more efficient ...

Around 115 million years ago, northern Australia’s seas hosted a colossal shark that rewrites what we thought we knew about early ocean predators. New fossil discoveries show that modern-type ...

Researchers discovered that raising the protein Sox9 can help the brain’s astrocytes clear out toxic plaque buildup linked to Alzheimer’s. In mouse models that already showed memory problems, ...

A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and ...

Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered ...

Researchers discovered that chemotherapy can accidentally trigger a stress alarm in immune cells, causing inflammation that damages nerves. Blocking this alarm protected mice from nerve pain and kept ...

A new airflow device from UBC Okanagan engineers traps exhaled aerosols almost immediately, sharply reducing pathogen exposure in indoor spaces. Early simulations suggest it could outperform existing ...

About 4.5 billion years ago, a colossal impact between the young Earth and a mysterious planetary body called Theia changed everything—reshaping Earth, forming the Moon, and scattering clues across ...

Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or ...

Scientists have created a live-cell DNA sensor that reveals how damage appears and disappears inside living cells, capturing the entire repair sequence as it unfolds. Instead of freezing cells at ...

A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing ...

Researchers taught young loggerhead turtles to associate certain magnetic fields with feeding, prompting a distinctive dance when they recognized the signal. After a magnetic pulse briefly disrupted ...

Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a ...

Researchers have launched the first coordinated plan to protect microbial biodiversity, calling attention to the “invisible 99% of life” that drives essential Earth systems. The IUCN has formally ...

Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling ...

Scientists discovered that deep earthquake faults can heal far faster than expected, sometimes within hours. Slow slip events in Cascadia reveal repeated fault movements that only make sense if the ...

Migratory birds that fill North American forests with spring songs depend on Central America’s Five Great Forests far more than most people realize. New research shows these tropical strongholds ...
