Floating-electron catalyst withstands week in air while making ammonia under milder condit

A surface electrene, BaSiN2:O, developed by researchers at Science Tokyo enables efficient ammonia synthesis under mild conditions while overcoming the long-standing air instability of electrene materials. Synthesized by doping barium silicon nitride with oxygen, the material for

Popular weight-loss drugs Ozempic and Wegovy may slow biological aging

Researchers found that semaglutide, the active ingredient in Ozempic and Wegovy, slowed biological aging markers in adults with HIV, marking the first clinical evidence that the drug may influence human aging. Although the findings are encouraging, scientists say larger studies a

Frame-dragging observations validate Einstein yet again

More than a century after Albert Einstein first transformed our understanding of gravity, his general theory of relativity continues to withstand ever more demanding experimental tests. Now, an international team led by Ignazio Ciufolini at the Chinese Academy of Sciences has car

A 37-year soil experiment revealed a hidden climate threat

The world's longest-running soil warming experiment has revealed an unexpected climate concern. After nearly four decades, researchers found that warming can cause microbes to break down stable soil carbon that scientists once believed was largely protected. That releases extra c

Disturbance has a greater effect on giant kelp productivity than resource availability

Marine scientists at UC Santa Barbara have found that disturbances to giant kelp forests have a major influence on their net primary productivity (NPP)—an indicator of an ecosystem's health and its ability to support its community—even more so than the availability of the resourc

Are there aliens on exoplanet K2-18b? Scientists just scanned it for signals

K2-18b is one of the most promising worlds for the search for extraterrestrial life, so astronomers conducted an unusually powerful radio survey using both the VLA and MeerKAT telescopes. Advanced software analyzed millions of signals, filtering out Earth-based interference and o

Eating chili peppers may raise the risk of one deadly cancer

A major review found that people who consumed the most chili peppers had a substantially higher risk of esophageal cancer, though the evidence was less clear for stomach and colorectal cancers. Researchers emphasize that the findings show an association, not proof of cause and ef

Watchdog science journalism: Crucial yet precarious work, according to study

How do journalists act as watchdogs of science? New qualitative research led by University of Amsterdam media scholar Alice Fleerackers sheds light on the labor-intensive nature of watchdog science journalism, a form of critical journalism that scrutinizes science. It shows that

Chewing bubble gum after beetroot may help lower blood pressure

A new study found that chewing sugary gum after eating nitrate-rich vegetables or drinking beetroot juice helped the body produce more beneficial nitrite, leading to a temporary drop in blood pressure. Researchers hope the discovery will lead to healthier ways to enhance the card
