Melting ice from West Antarctica once delivered huge amounts of iron to the Southern Ocean, but algae growth did not increase as expected. Researchers found the iron was in a form that marine life could not easily use. This means more melting ice does not automatically boost carbon absorption. In the future, Antarctic ice loss could actually reduce the ocean’s ability to slow climate change.

Scientists are digging into why heart disease risk in type 2 diabetes differs between men and women—and sex hormones may be part of the story. In a large Johns Hopkins study, men with higher testosterone had lower heart disease risk, while rising estradiol levels were linked to higher risk. These hormone effects were not seen in women. The results point toward more personalized approaches to hear…

Scientists have uncovered a surprising genetic shift that may explain how animals with backbones—from fish and frogs to humans—became so complex. By comparing sea squirts, lampreys, and frogs, researchers found that key genes controlling cell communication began producing many more protein variations right at the moment vertebrates emerged. This genetic flexibility likely helped cells specialize …

Sound machines may not be the sleep saviors many believe. Researchers found that pink noise significantly reduced REM sleep, while simple earplugs did a better job protecting deep, restorative sleep from traffic noise. When pink noise was combined with outside noise, sleep quality dropped even further. The results suggest that popular “sleep sounds” could be doing more harm than good—particularly…

Plants make chemical weapons to protect themselves, and many of these compounds have become vital to human medicine. Researchers found that one powerful plant chemical is produced using a gene that looks surprisingly bacterial. This suggests plants reuse microbial tools to invent new chemistry. The insight could help scientists discover new drugs and produce them more sustainably.

As we age, our cells don’t just wear down—they reorganize. Researchers found that cells actively remodel a key structure called the endoplasmic reticulum, reducing protein-producing regions while preserving fat-related ones. This process, driven by ER-phagy, is tied to lifespan and healthy aging. Because these changes happen early, they could help trigger later disease—or offer a chance to stop i…

A newly identified tiny dinosaur, Foskeia pelendonum, is shaking up long-held ideas about how plant-eating dinosaurs evolved. Though fully grown adults were remarkably small and lightweight, their anatomy was anything but simple—featuring a bizarre, highly specialized skull and unexpected evolutionary traits. Detailed bone studies show these dinosaurs matured quickly with bird- or mammal-like met…

Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer than similar low-cost materials. Surprisingly, the improved manganese catalyst even beat many expensive precious-metal options. The discovery could …

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA’s James Webb Space Telescope, the research shows how dark matter gathered ordinary matter into dense regions, setting the stage for galaxies like the Milky Way and eventually planets like Ear…

A new brain imaging study reveals that remembering facts and recalling life events activate nearly identical brain networks. Researchers expected clear differences but instead found strong overlap across memory types. The finding challenges decades of memory research. It may also help scientists better understand conditions like Alzheimer’s and dementia.

Even in some of the most isolated corners of the Pacific, plastic pollution has quietly worked its way into the food web. A large analysis of fish caught around Fiji, Tonga, Tuvalu, and Vanuatu found that roughly one in three contained microplastics, with Fiji standing out for especially high contamination. Reef and bottom-dwelling fish were most affected, linking exposure to where fish live and …

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed scientists to measure multiple “tones” from the collision, all matching Einstein’s predictions. That confirmation is exciting—but so is the possibility that future signals won’t behave so neatly. Any devi…

MMS has long been promoted as a miracle cure, but new research shows it’s essentially a toxic disinfectant. While it can kill bacteria, it only works at levels that also damage human cells and beneficial gut microbes. Scientists warn that homemade MMS mixtures are especially dangerous due to wildly inconsistent dosing. The study calls MMS a clear case where the risks are high—and the benefits are…

Chronic stress can damage the gut’s protective lining, triggering inflammation that may worsen depression. New research shows that stress lowers levels of a protein called Reelin, which plays a key role in both gut repair and brain health. Remarkably, a single injection restored Reelin levels and produced antidepressant-like effects in preclinical models. The findings hint at a future treatment t…

New research reveals a forgotten side of medieval Christianity—one rooted not in cathedrals, but in fields, forests, and farms. Historian Dr. Krisztina Ilko uncovers how the Augustinian order built its power through “green” miracles: restoring barren land, healing livestock, reviving fruit trees, and taming deadly landscapes once blamed on dragons. Far from symbolic tales, these acts helped rural…
