A 25-year study found that frequent consumption of soda, sports drinks, and fruit juice beginning in childhood was linked to a higher risk of high blood pressure in adulthood. Swapping one daily drink for whole fruit, milk, or water could significantly reduce that risk.
Scientists may be able to reliably forecast Antarctic ice loss through the middle of this century, offering governments a vital head start on sea level rise. After that, unstable ice retreat could accelerate dramatically, making the future much harder to predict.
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal. During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, allowing crews and ground teams to test the complex maneuvers needed for later missions.
A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust. Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets.
Researchers have developed a fluoride-free gel that could help rebuild damaged tooth enamel, something the body cannot naturally replace once it is lost. Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic cracks and draws calcium and phosphate from saliva to grow a new mineral layer that closely matches healthy enamel.
A plant-derived compound reduced swelling, inflammation, and joint damage in rats with rheumatoid arthritis. It also helped rebalance immune activity and improve the way certain fats were processed in the body. Researchers say the findings could lead to a new approach for treating the disease.
Researchers found that specific brain circuits help decide which jobs bees perform as they age. When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties. The findings reveal that a bee colony’s complex division of labor may be guided by neural switches hidden inside each bee’s brain.
Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction. New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the devastation.
Colorectal cancer is now the leading cause of cancer death among people under 50, and cases in younger adults continue to rise. Warning signs can include persistent bowel changes, recurring rectal bleeding, dark or narrow stools, unexplained weight loss, and fatigue. These symptoms often have harmless causes, but they should not be dismissed, especially when they are new or ongoing. Early detection can greatly improve treatment outcomes.
Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant. The organoids and the particles they release could eventually guide more personalized treatments and provide new clues for diagnosing the disease.
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules. The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started. This quantum-driven shuttle could offer a powerful new way to tune solar cells, lasers, and catalytic reactions.
MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts. Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals. In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view.
