Stanford Medicine researchers have discovered a naturally occurring molecule that may suppress appetite and reduce body weight much like Ozempic, but without several of its common side effects. The molecule, called BRP, acts on a more targeted region of the brain involved in hunger and metabolism rather than affecting tissues throughout the body.
A sulfur-based compound called LASSS appears to protect and supercharge a key protein involved in repairing damaged muscle. The discovery could eventually lead to new ways to slow muscle loss and preserve strength as people age.
An experimental pill prevented a measles-like virus from spreading through the air or through close contact in ferrets. It worked when given shortly before or after exposure and also shortened illness and the period when infected animals remained contagious. Researchers say the drug could one day complement vaccination and make outbreaks easier to contain.
Ozempic, Wegovy, and similar drugs may deliver excellent health value, but covering them for millions of eligible patients could overwhelm insurance budgets. Researchers say better long-term support is needed and warn that low-cost compounded versions may carry serious safety risks.
Sweden could become an important source of rare earth elements needed for magnets and green technologies. Instead of extracting one target metal, researchers are cataloging everything contained in Swedish mineral deposits. They will then develop magnets using those naturally available combinations, potentially reducing pollution, waste, and reliance on China.
China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars. The images reveal its tail and glowing coma, offering scientists a glimpse of material born beyond our solar system.
A newly identified fossil ape from northern Egypt is reshaping ideas about where the ancestors of modern apes first emerged. Analyses place it closer to living apes than any known East African species of the same age, pointing to North Africa and the Middle East as a possible birthplace and crossroads for the ape lineage that eventually produced gibbons, orangutans, gorillas, chimpanzees, and humans.
The longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress. The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s.
A large study suggests that GLP-1 drugs including Ozempic and Mounjaro may slightly increase the risk of hair loss in people with type 2 diabetes. Compared with two other common classes of diabetes medications, GLP-1 users had a significantly higher rate of alopecia, though the absolute risk was still low. The hair loss was mainly non-scarring, which means it may be reversible.
Fossils discovered in Japan more than two decades ago have finally been identified as a new genus and species of giant salamander. Limnospondylus ajimuensis lived around 3.5 million years ago in a warmer, wetter Kyushu and may have reached 1.1 meters in length. Its discovery hints that many more unknown giant salamanders could be hiding among fossils previously given the wrong classification.
Researchers in the Gulf of California have documented a dramatic orca behavior never described before. In two separate encounters, one orca gripped a dead sunfish by the fin while another charged into it at high speed, blasting the carcass into thousands of pieces.
A global shift toward healthier diets could sharply reduce livestock farming, free up agricultural land, and cut emissions from land-use change by 85% by 2050. At the same time, fruit, vegetable, nut, and legume production could soar, creating a sweeping transformation of what the world grows and eats.
