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 […] Read more…
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 […] Read more…
2025-08-28 22:11:41 +00:00 At current emission rates, the world has just over three years before surpassing the carbon budget needed to limit warming to 1.5 °C. Rising seas, hotter oceans, and record-breaking global temperatures underline how rapidly the climate crisis is accelerating and why urgent action is critical. Carbon Budget Nears Critical Threshold The latest Indicators of Global Climate […] Read more…
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 […] Read more…
2025-08-28 18:32:46 +00:00 A new ultra-detailed map of the Sculptor Galaxy exposes stellar life and hidden structures, offering new insights into how small-scale processes influence entire galaxies. Astronomers have unveiled a remarkable new view of the Sculptor Galaxy, producing a highly detailed image that exposes features never seen before. The achievement comes from observations with the European Southern […] Read more…
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 […] Read more…
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 […] Read more…
2025-08-28 14:14:22 +00:00 Restricted blood flow speeds tumor growth by aging the immune system. The findings highlight risks for patients with vascular disease and potential new therapies. A new study from NYU Langone Health reports that restricted blood flow can accelerate the aging of bone marrow, reducing the immune system’s ability to combat cancer. The research, published on […] Read more…
2025-08-28 13:49:10 +00:00 A study in rats questions long-standing views on hypertension and suggests the brain may serve as a new target for treatment. A recent study shows that consuming a diet high in salt causes inflammation in the brain, which in turn raises blood pressure. The work, led by McGill University scientist Masha Prager-Khoutorsky in partnership with […] Read more…
2025-08-28 13:24:04 +00:00 Common painkillers like ibuprofen and acetaminophen may fuel antibiotic resistance, raising urgent questions about drug interactions in aged care and beyond. Ibuprofen and acetaminophen (paracetamol) are among the most widely used pain and fever remedies, but new findings from the University of South Australia suggest they may be contributing to a global health crisis: antibiotic […] Read more…
2025-08-28 09:58:53 +00:00 Discovery reveals a previously undocumented 30-million-year gap in dragonfly evolution.
