A distant Sun-like star suddenly went dark for months, stunning astronomers who quickly realized something massive was passing in front of it. Observations revealed a gigantic disk of gas and dust filled with vaporized metals, swirling around an ...

Chronic inflammation may be quietly reshaping the colon and making it more vulnerable to early-onset colorectal cancer. Scientists found that colon tissue in younger patients was stiffer, even in areas that appeared healthy, suggesting these changes ...

Aging immune cells may be sabotaging the body from within. Researchers found that macrophages produce a protein that locks them into a chronic inflammatory state, making infections like sepsis more deadly in older adults. Turning off this signal ...

People with spinal cord injuries often lose movement even though their brains still send the right signals. Researchers tested whether EEG brain scans could capture those signals and reroute them to spinal stimulators. The system can detect when a .. ...

Locust swarms can wipe out crops across entire regions, threatening food supplies and livelihoods. Now, scientists working with farmers in Senegal have shown that improving soil health can dramatically reduce locust damage. By enriching soil with ...

A large, decades-long study suggests that signs of ADHD in childhood may have consequences that extend well beyond school and behavior. Researchers followed nearly 11,000 people from childhood into midlife and found that those with strong ADHD traits ...

Scientists are finding new ways to replace expensive, scarce platinum catalysts with something far more abundant: tungsten carbide. By carefully controlling how tungsten carbide's atoms are arranged at extremely high temperatures, researchers ...

A groundbreaking new radio image reveals the Milky Way in more detail than ever before, using low-frequency radio "colors" to map the galaxy's hidden structures. The image is sharper, deeper, and wider than anything previously released, uncovering .. ...

Astronomers have spotted a rare, rule-breaking quasar in the early Universe that appears to be growing its central black hole at an astonishing pace. Observations show the black hole is devouring matter far faster than theory says it should--about 13 ...

Giant kangaroos that lived during the Ice Age may not have been as slow and grounded as once believed. A new study finds their leg bones and tendons were likely strong enough to support hopping, despite their massive size. Rather than traveling this ...
