Africa’s Giant Herbivores Were Disappearing Millions of Years Before Humans Could Hunt Them   2026-09-07 11:31:55 +00:00 Africa’s giant herbivores did not simply vanish in a wave of extinctions. Their evolutionary family tree was slowly running out of new branches. A new study suggests that the long decline of animals such as elephants, hippopotamuses, and their extinct relatives was driven primarily by low rates of speciation. Once a giant species disappeared, another [...] Read more...   This Utah Mountain Is Hiding Enough Ice To Fill 600 Olympic Pools   2026-09-07 10:16:31 +00:00 A mountain of loose rock in Utah hides enough ice to fill 600 Olympic swimming pools, revealing that some of the state’s largest frozen water reserves are almost invisible from the surface. Unlike conventional glaciers, which expose broad expanses of ice, rock glaciers resemble slowly shifting fields of broken stone. Their rocky coverings can conceal [...] Read more...   Vagus Nerve Stimulation Could Unlock the Brain’s Hidden Learning Potential   2026-09-07 00:11:57 +00:00 Practice may teach the brain a new movement, but what happens immediately afterward could determine whether that skill lasts. Scientists have long known that repetition alone does not guarantee learning. A newly practiced movement must be stabilized through memory consolidation, a process that continues after training ends. New research in mice suggests that signals arriving [...] Read more...   Your Mother’s Age May Leave a Biological Mark That Lasts for Generations   2026-09-06 22:56:50 +00:00 Maternal age effects may arise from reversible epigenetic changes whose impact depends partly on genetics and evolutionary pressures. A mother’s age can leave a biological imprint on her offspring, influencing physical and behavioral traits across many animal species, including humans. These so-called maternal age effects are widespread, but scientists still do not fully understand the [...] Read more...   Women Who Ate More Antioxidants Had Strikingly Lower Rates of Cervical Cancer   2026-09-06 19:31:34 +00:00 Women with the most antioxidant-rich diets had a strikingly lower prevalence of cervical cancer in a nationwide analysis. A cervical cancer diagnosis is usually traced back to one dominant cause: persistent infection with a high-risk strain of human papillomavirus (HPV). But infection alone does not determine who develops cancer, leaving researchers interested in the other [...] Read more...   A Hidden Hormone Disorder May Be Driving Millions of High Blood Pressure Cases   2026-09-06 18:16:56 +00:00 A hidden hormone disorder may be driving millions of cases of high blood pressure, and a wearable device is revealing what standard tests miss Researchers have used a wearable device to uncover previously hidden hormone patterns in primary aldosteronism, a potentially curable disorder that may affect as many as one in five people with high [...] Read more...   This Self-Rebuilding Electrode Could Supercharge Green Hydrogen Production   2026-09-06 15:56:32 +00:00 A metal surface that becomes more active as it changes could help green hydrogen electrolyzers run harder and longer. Researchers at the Chinese Academy of Sciences have developed an electrode that combines five metals in a high-entropy antiperovskite structure. Supported on porous nickel foam, the material helped an anion exchange membrane (AEM) electrolyzer sustain industrially [...] Read more...   These Light-Powered Robots Can Keep Jumping Forever   2026-09-06 14:41:39 +00:00 A self-resetting soft robot can repeatedly jump under infrared light, with simple design changes controlling how and where it moves. A teardrop-shaped soft robot developed at North Carolina State University can keep jumping for as long as infrared light shines on it, without needing to be reset between leaps. Depending on a simple change to [...] Read more...   Ancient Human Teeth Uncover a Genetic Connection Hidden for 400,000 Years   2026-09-06 12:02:43 +00:00 Enamel proteins from Homo erectus teeth suggest genetic links to Denisovans while offering a less destructive way to study ancient human fossils. A handful of ancient teeth may preserve clues to a relationship that has remained difficult to trace through fossils alone. Researchers from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese [...] Read more...   DNA Solves a 166-Year-Old Mystery From the Doomed Franklin Expedition   2026-09-06 10:47:45 +00:00 New research reveals more details about the doomed mission to find the Northwest Passage. Researchers have now identified four additional members of Sir John Franklin’s 1845 expedition, including one sailor whose identity had been debated for more than 100 years. The work was led by anthropologists in the Faculty of Arts at the University of [...] Read more...   Researchers Discover a Gut Microbe Metabolite That Supercharges Cancer Immunotherapy   2026-09-06 02:33:17 +00:00 A microbial metabolite called 3,4 dihydroxybenzoic acid, derived from dietary fiber, improved antitumor immunity in mice. A compound made by gut bacteria during the breakdown of dietary fiber may offer a way to strengthen cancer immunotherapy. In mouse studies, University of Michigan researchers turned that compound into an oral drug that helped T cells attack [...] Read more...   How Often You Exercise May Matter More Than How Hard You Work Out for Mental Health   2026-09-06 01:18:25 +00:00 When it comes to reducing the risk of depression and anxiety, how often students exercise may matter more than how hard they push themselves. A large Norwegian study found that students who exercised infrequently were more likely to develop clinically defined depression, anxiety, or another common mental disorder over the following year. How often they [...] Read more...
