| Each Winter, These Tiny Ocean Travelers Bury Millions of Tons of Carbon |
|
|
2025-08-28 23:01:42 +00:00
 Every year, billions of microscopic ocean drifters—copepods, krill, and other zooplankton—perform a breathtaking migration in the Southern Ocean, diving hundreds of meters into the deep. As they descend to hibernate for the winter, they carry carbon from the surface with them and, through respiration and mortality, lock it away beneath 500 meters. This newly quantified […]

| Healing Ozone Layer Could Trigger 40% More Global Warming |
|
|
2025-08-28 22:36:36 +00:00
 As the ozone layer recovers, it’s also intensifying global warming. Researchers predict that by 2050, ozone will rank just behind carbon dioxide as a driver of heating, offsetting many of the benefits from banning CFCs. The planet is now expected to heat up more than scientists once predicted, and a major reason lies in the […]

|
|
2025-08-28 19:07:49 +00:00
 Two spacecraft mimicked a solar eclipse to capture rare images of the Sun’s corona. The mission also helps predict hazardous space weather. During a natural solar eclipse, heliophysicists have a rare opportunity to investigate the Sun’s corona, the outermost layer of its atmosphere, in ways that are not normally possible. The Sun’s inner regions shine […]

| Physicists Discover Universal Laws Governing Quantum Entanglement |
|
|
2025-08-28 16:44:53 +00:00
 Scientists uncovered universal laws of entanglement in any dimension. The results strengthen links between particle physics, quantum theory, and gravity. A group of theoretical physicists has shown that quantum entanglement obeys universal principles in every dimension by applying thermal effective theory. Their findings were recently published in the journal Physical Review Letters, where the paper […]

| Scientists Crack a 40-Year Puzzle in Unbreakable Encryption |
|
|
2025-08-28 16:09:35 +00:00
 For decades, scientists thought unbreakable quantum encryption required flawless light sources, a nearly impossible feat. But a team has flipped the script using tiny engineered “quantum dots” and clever new protocols. By making imperfect light behave more securely, they proved that encrypted messages can travel farther and more safely than ever before. Real-world tests have […]
