2025-12-07 03:38:00 +00:00
 NOAA and NASA report that the 2025 ozone hole over Antarctica was far smaller and shorter-lived than usual. Falling chlorine levels and a weaker polar vortex helped limit ozone loss this season. These findings add to decades of evidence showing that the Montreal Protocol is working. Scientists expect the ozone layer to keep strengthening in […]

| Decades Later, Scientists Finally Explain Voyager 2’s Bizarre Readings at Uranus |
|
|
2025-12-06 22:14:19 +00:00
 Powerful waves unleashed by solar storms could be the key to understanding extreme radiation. Southwest Research Institute (SwRI) researchers now think they have found the answer to a puzzle that has lingered for nearly four decades involving Uranus and its unusual radiation environment. When Voyager 2 completed its first and only visit to the planet […]

| New Research Identifies Who Actually Benefits From Daily Multivitamins |
|
|
2025-12-06 19:41:44 +00:00
 Multivitamins showed no broad effect on blood pressure in older adults, but they offered small, meaningful benefits for those with poorer diets or normal baseline BP. New findings from Mass General Brigham investigators indicate that taking a daily multivitamin over a long period may help lower the risk of developing hypertension and may also reduce […]

| New Research Shows How Bad Air Cuts Exercise Benefits in Half |
|
|
2025-12-06 19:06:42 +00:00
 Scientists found that toxic air can greatly reduce the protective effects of exercise, although it doesn’t erase them completely. When PM2.5 pollution passes widely experienced thresholds, the health boost from regular activity drops noticeably and can fall to roughly half its usual strength. Toxic Air Exposure Weakens Exercise Benefits A new international study involving experts […]

2025-12-06 14:15:38 +00:00
 A new study highlights the key role the Southern Ocean plays in the Earth’s climate system. Around 12,000 years ago, the last Ice Age drew to a close, global temperatures climbed, and the early Holocene began. During this period of warming, human communities gradually shifted toward more permanent settlements. A new study published in Nature […]
