New research suggests the astringent sensation caused by flavanols could act as a direct signal to the brain, triggering effects similar to a mild workout for the nervous system. In mouse experiments,...
Fossils from a Moroccan cave have been dated with remarkable accuracy to about 773,000 years ago, thanks to a magnetic signature locked into the surrounding sediments. The hominin remains show a blend...
New simulations reveal that both H1N1 and COVID-19 spread across U.S. cities in a matter of weeks, often before officials realized what was happening. Major travel hubs helped drive rapid nationwide t...
A major study suggests menopause is linked to changes in brain structure, mental health, and sleep. Brain scans revealed grey matter loss in areas tied to memory and emotional regulation, while many w...
For decades, Americans were surrounded by lead from car exhaust, factories, paint, and even drinking water, often without realizing the damage it caused. By analyzing hair samples preserved across gen...
Arctic sea ice helps cool the planet and influences weather patterns around the world, but it is disappearing faster than ever as the climate warms. Scientists have now developed a new forecasting met...
New research suggests that Epstein-Barr virus may actively provoke the immune system in people with multiple sclerosis. Scientists found large buildups of virus-targeting immune cells in the nervous s...
Researchers have discovered a previously unknown enzyme that plays a crucial role in fat production. By blocking it, they stopped weight gain, reduced liver damage, and lowered harmful cholesterol lev...
Inspired by the shape-shifting skin of octopuses, Penn State researchers developed a smart hydrogel that can change appearance, texture, and shape on command. The material is programmed using a specia...
Colorectal cancer has long baffled scientists because, unlike most tumors, patients often do better when their cancers are packed with immune-suppressing regulatory T cells. New research finally expla...
Quantum computers struggle because their qubits are incredibly easy to disrupt, especially during calculations. A new experiment shows how to perform quantum operations while continuously fixing error...
Scientists at Keck Medicine of USC are testing an experimental stem cell therapy that aims to restore the brain’s ability to produce dopamine, the chemical whose loss drives Parkinson’s disease. The e...
