Millipedes Preceded Vertebrates on Land by 80 Million Years, Study Reveals

Millipedes may have been crawling across Earth's landscapes nearly 460 million years ago, long before vertebrates ventured onto land. A new study has finally completed their evolutionary family tree, revealing surprising clues about these ancient ecosystem engineers and their early chemical defenses. The research provides a comprehensive view

Study Finds GLP-1 Weight Loss Drug Users Are Moving Less Despite Successful Weight Loss

Reduced Activity Despite Weight Loss A growing body of research is examining the effects of GLP-1 receptor agonists—a class of drugs that includes Ozempic, Wegovy, Mounjaro, and Zepbound—on patient health outcomes beyond just the numbers on the scale. Key Findings Researchers analyzed Fitbit data from users who began

Scientists Challenge Decades-Old Yellowstone Wolf Trophic Cascade Claim

Study Challenges Iconic Ecological Narrative One of the most celebrated claims in ecology about Yellowstone's wolves is facing a major challenge. Scientists have reexamined the landmark study behind the famous trophic cascade story, which had suggested that wolf recovery dramatically reshaped the national park's ecosystem. The

Dark Energy Challenge Fails: Cosmic Acceleration Remains Unchanged

A bold challenge to one of cosmology's most important findings appears to have failed. A previous study had suggested that the universe's accelerating expansion might be an illusion, but researchers have now shown that the controversial claim relied on errors in how supernova data was analyzed.

NASA's X-59 Experimental Jet Breaks Sound Barrier for First Time

NASA's X-59 experimental jet has successfully broken the sound barrier for the first time, according to reports from Live Science. This milestone represents a significant step forward in the development of "quiet supersonic" technology, which aims to reduce the disruptive sonic boom associated with aircraft traveling
