More than 400,000-year-old Homo erectus teeth from China may reveal a surprising link between this ancient human species, Denisovans, and some modern people. Scientists found protein mutations suggesting several East Asian Homo erectus populations .. ...

Scientists discovered that charged water droplets can damage protective coatings by releasing tiny electrical discharges when they hit a surface. The hidden effect could help explain weathering and lead to tougher coatings for cars, bridges, ...

An experimental compound called AP503 significantly strengthened bones in mice by activating GPR133, a receptor that boosts bone formation while slowing bone loss. Because the same treatment has also been linked to stronger muscles, researchers see . ...

Semaglutide, the drug found in Ozempic and Wegovy, was linked to nearly 40% fewer asthma attacks in a large real-world study. It was also associated with about 20% fewer COPD flare-ups. Researchers say GLP-1 drugs may offer respiratory benefits in .. ...

Two major alien-life announcements in 2025 generated enormous excitement, but most astrobiologists remained unconvinced. Only 6.6% of surveyed experts thought possible biological molecules on K2-18b probably represented extraterrestrial life, while . ...

Interstellar comet 3I/ATLAS contains exceptionally high levels of methanol, suggesting it formed under conditions very different from those that shaped most comets in our solar system. ALMA also revealed that tiny icy grains around the comet are ...

Britain's towering Devil's Arrows were built from 25-tonne stones hauled at least 18 kilometers from Brimham Rocks around 4,000 years ago. The discovery reveals an astonishing feat of prehistoric engineering and suggests the stones' distant source .. ...

Insects quietly hold much of the natural world together, yet conservation efforts are overlooking the tropical regions where more than 80 percent of insect species live. Monash University researchers have developed a global framework to close this .. ...

Scientists found that a tiny atomic structure that forms on nickel oxide during methane conversion is more effective than the metallic nickel long believed to drive the reaction. The discovery allowed a low-nickel catalyst to rival one containing 10 ...

Volcanic rocks in Colombia are rewriting the timeline of the collision between Central and South America. Their magnetic signatures show that major tectonic deformation had already weakened by the late Miocene, suggesting the most intense collision . ...
