A newly identified mosasaur from Texas suggests that some ancient marine predators were larger, more powerful, and possibly more aggressive than previously recognized. Bite marks, broken jaws, and a giant skull from Texas are helping scientists redraw the family tree of one of the ocean’s most fearsome ancient predators. The animal behind the evidence was [...]

Scientists have taken a major step toward safely freezing and reviving brain tissue by preventing the microscopic damage normally caused by ice crystals. What if living tissue could be frozen for years, or even decades, and later revived without losing its function? Scientists searching for ways to make this possible have turned to an unlikely [...]

As bees and hummingbirds move from flower to flower collecting nectar and pollinating plants, they may also be consuming small amounts of alcohol. In the first large-scale study examining alcohol in floral nectar, biologists at the University of California, Berkeley detected ethanol in at least one flower sample from 26 of the 29 plant species [...]

Obesity may worsen Alzheimer’s disease through fat molecules that send harmful signals to the brain, but targeting those molecules could offer a new path for intervention. Alzheimer’s disease is often viewed as a disorder that begins and ends in the brain. But growing evidence suggests the disease may also be shaped by what happens throughout [...]

Researchers reviewing decades of evidence conclude that alcohol plays a major role in disease and injury, affecting everything from the immune system to the brain and heart. A major new review published in Addiction paints a sobering picture of alcohol’s impact on health, linking drinking to dozens of diseases, infections, and injuries that affect nearly [...]

Scientists at UC Riverside uncovered evidence that compounds beyond THC may influence how the body regulates metabolism and insulin signaling. A preclinical study from the University of California, Riverside offers new insight into a puzzling pattern that scientists have noticed for years: people who use cannabis chronically often have lower body weight and a lower [...]

A decades-old patent from MIT Professor Bill Freeman inspired the new “Y-zipper,” a three-sided fastener that can snap gear, robots, and art into shape with the push of a button. Long before shape-shifting robots and self-assembling structures became engineering goals, one MIT professor had already imagined a zipper that could transform floppy materials into rigid [...]

NASA’s Psyche spacecraft just used Mars as a giant slingshot on its journey to a mysterious metal world that could reveal what’s hidden inside planets like Earth. NASA’s Psyche spacecraft successfully completed a close flyby of Mars on May 15, passing just 2,864 miles (4,609 kilometers) above the planet’s surface. The maneuver used Mars’ gravity [...]

Ancient asteroid craters may have been safe havens for Earth’s earliest oxygen-producing life. Scientists in South Korea have uncovered evidence suggesting that asteroid impact craters may have played an important role in the rise of oxygen-producing life on early Earth. A research team from the Korea Institute of Geoscience and Mineral Resources (KIGAM) discovered stromatolites [...]

A long-running study suggests that one of the simplest ways to support healthy aging may also be one of the most effective: eating slightly fewer calories. Search online, and you will find countless biohacking trends that promise healthier aging, from cold plunges and hyperbaric oxygen therapy to sleeping under red lights. But research from Tufts [...]

New research suggests grapes may offer surprising benefits for skin health by changing how genes behave in the body. Earlier clinical trials showed that eating grapes could improve resistance to UV radiation in about 30% to 50% of people. Now, scientists say the effects appear to be much broader and may influence nearly everyone in [...]

A new “Trojan horse” weight-loss drug sneaks extra metabolic power into cells and delivers striking results in mice. Researchers at Helmholtz Munich have developed a new drug strategy that could improve treatment for obesity and type 2 diabetes. Led by metabolism scientist Prof Timo D. Müller, the team created a hybrid molecule that uses the [...]

Unusual fat deposits in domestic cat kidneys may reveal why cats are especially vulnerable to chronic kidney disease. Scientists at the University of Nottingham have identified an unexpected feature of domestic cat biology that could help explain their high risk of chronic kidney disease. Compared with dogs and most other mammals, domestic cats seem to [...]

Warming is making Himalayan rivers more unstable, with potentially serious consequences downstream. The Himalayas do more than tower over Asia. They help store and release the water that feeds some of the continent’s most important rivers, supporting nearly 2 billion people from mountain valleys to densely populated plains. Now, a new study suggests that this [...]

An analysis found that Climate TRACE may substantially underestimate city vehicle CO2 emissions, raising concerns about data accuracy in climate policy. Some of the world’s most widely used climate emissions estimates could be missing far more pollution than anyone realized. A new study from Northern Arizona University reports that the global greenhouse gas emissions database [...]

A new study suggests the gut microbiome may retain long-term signatures of past medication use, with some drugs leaving detectable effects years after treatment ends. Your gut may carry a record of medications you stopped taking years ago. A large study from the University of Tartu Institute of Genomics suggests that prescription drugs can leave [...]

Researchers have identified a vitamin B12–based compound that appears capable of crossing the blood–brain barrier and selectively accumulating in glioblastoma tissue. For decades, one of the biggest problems in brain cancer treatment has had little to do with killing cancer cells and everything to do with reaching them. The brain’s protective blood-brain barrier (BBB) blocks [...]

Scientists are uncovering why some dietary fats may worsen metabolic disease while others appear to help protect against it. A new study is shedding light on how two common dietary fats may influence the risk of developing type 2 diabetes, a disease linked to serious health complications worldwide. The research, published in Trends in Endocrinology [...]

Birmingham researchers have developed a new method for producing hydrogen fuel that costs less than existing approaches. Hydrogen has long been hailed as a key fuel for a low-carbon future, capable of powering everything from heavy industry to transportation without producing carbon emissions at the point of use. Yet there is a major contradiction at [...]

New measurements of nickelate superconductors reveal clues about their hidden electronic behavior. The mechanism behind high-temperature (TC) superconductivity remains one of condensed matter physics’ major unsolved problems. Chinese researchers have now made important progress in studying high-TC nickelate superconductors. For the first time, scientists identified a nodeless superconducting gap …
