Scientists have finally found a hidden "critical point" in supercooled water that explains why it behaves so strangely. At this point, two different liquid forms of water merge, triggering powerful fluctuations that affect water even at normal ...

A team of physicists set out to test some of the most exciting claims in quantum computing--and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances . ...

After a stroke, the brain may do something surprisingly hopeful--it can "refresh" parts of itself. Researchers analyzing brain scans from over 500 stroke survivors found that while the damaged side of the brain appears to age faster, the opposite, .. ...

A major new U.S. cholesterol guideline is shifting the focus toward earlier, more personalized prevention of heart disease. It urges people to start screening sooner--sometimes even in childhood--and highlights the importance of tracking not just LDL ...

Nicotine e-cigarettes may be one of the most effective tools yet for quitting smoking, according to a sweeping review of global research. By analyzing findings from 14 major reviews spanning nearly a decade, researchers found consistent, high-quality ...

Scientists have developed a new gene therapy that quiets pain at its source in the brain--without the addictive risks of opioids. Using AI to map how pain is processed, they created a targeted "off switch" that mimics morphine's benefits but skips .. ...

Scientists have created a new kind of carbon material that could make carbon capture much cheaper and more efficient. By carefully controlling how nitrogen atoms are arranged, they found certain structures capture CO2 better and release it using far ...

For decades, astronomers have been puzzled by strange "zebra stripe" patterns in radio waves from the Crab Pulsar -- bright bands separated by complete darkness. Now, new research suggests the answer lies in a cosmic tug-of-war between gravity and .. ...

A widely used sugar substitute found in everything from keto snacks to diet drinks may not be as harmless as it seems. New research shows that erythritol can disrupt brain blood vessel cells, reducing their ability to relax, increasing harmful ...

Scientists have uncovered how your body actually tells your brain to stop eating when you're sick. In a new study, researchers found that specialized cells in the gut detect parasites and send signals that ultimately trigger the brain to suppress ...
