Ancient copper smelters may have accidentally set the stage for the Iron Age. At a 3,000-year-old workshop in Georgia, researchers discovered that metalworkers were using iron oxide not to smelt iron but to improve copper yields. This experimentation ...

Researchers discovered that autism's prevalence may be linked to human brain evolution. Specific neurons in the outer brain evolved rapidly, and autism-linked genes changed under natural selection. These shifts may have slowed brain development in .. ...

Beer and wine, staples of human history for millennia, are still yielding new surprises. Recent research highlights how yeast extracts can cloud lagers, gluten can be quickly detected with a simple test strip, tannins give red wine its lip-puckering ...

Daily cocoa extract supplements reduced key inflammation markers in older adults, pointing to a role in protecting the heart. The findings reinforce the value of flavanol-rich, plant-based foods for healthier aging.

Researchers have discovered an unusual "quantum echo" in superconducting materials, dubbed the Higgs echo. This phenomenon arises from the interplay between Higgs modes and quasiparticles, producing distinctive signals unlike conventional echoes. By ...

Scientists have uncovered an unexpected witness to Earth's distant past: tiny iron oxide stones called ooids. These mineral snowballs lock away traces of ancient carbon, revealing that oceans between 1,000 and 541 million years ago held far less ...

Scientists have identified three new species of deep-sea snailfish, including the strikingly pink "bumpy snailfish," thanks to MBARI's advanced technology and global collaborations. Found thousands of meters below the surface off California, these .. ...

Vincetoxicum nakaianum tricks flies into pollinating it by imitating the smell of ants attacked by spiders. Ko Mochizuki stumbled upon this finding when he noticed flies clustering around the flowers and later confirmed their unusual preference. The ...

New studies show that a bacterial molecule, peptidoglycan, is present in the brain and fluctuates with sleep patterns. This challenges the idea that sleep is solely brain-driven, instead suggesting it's a collaborative process between our bodies and ...

For decades, scientists believed Alzheimer's was driven mainly by sticky protein plaques and tangles in the brain. Now Purdue researchers have revealed a hidden culprit: fat. They found that brain immune cells can become clogged with fat, leaving ...
