Flatworms can rebuild themselves from just a small fragment, and now scientists know why. Their stem cells ignore nearby instructions and respond to long-distance signals from other tissues. This discovery turns old stem cell theories upside down and ...

People with gum disease may have higher levels of brain white matter damage, a new study finds. Researchers observed that participants with gum disease had significantly more white matter hyperintensities, even after accounting for other risk factors ...

UCL scientists found that human skulls evolved much faster than those of other apes, reflecting the powerful forces driving our brain growth and facial flattening. By comparing 3D models of ape skulls, they showed that humans changed about twice as . ...

Finnish scientists found that eicosapentaenoic acid (EPA) from fish oil impacts each person's metabolism uniquely. Participants showed strong but short-lived increases in EPA levels, with significant differences in lipid profiles. The results reveal ...

New research reveals that intelligence plays a key role in how well people process speech in noisy environments. The study compared neurotypical and neurodivergent individuals and found that cognitive ability predicted performance across all groups. ...

A new McGill-led study reveals that digital brain exercises can rejuvenate aging brain systems responsible for learning and memory. Older adults using BrainHQ for 10 weeks showed restored cholinergic function -- effectively turning back the brain's . ...

A team of scientists discovered a hidden antibiotic 100 times stronger than existing drugs against deadly superbugs like MRSA. The molecule had been overlooked for decades in a familiar bacterium. It shows no signs of resistance so far, offering hope ...

An international team of researchers led by scientists from the Max Planck Institute for Evolutionary Anthropology in Leipzig, working with 15 collaborators around the world, has conducted the most comprehensive study yet of lifespan differences ...

ETH Zurich scientists have created "MetaGraph," a revolutionary DNA search engine that functions like Google for genetic data. By compressing global genomic datasets by a factor of 300, it allows researchers to search trillions of DNA and RNA ...

A new study offers reassurance about the safety of certain processed fats found in everyday foods. Interesterified fats made from palm or plant oils didn't raise cholesterol or cause metabolic harm in healthy adults. The research challenges the idea ...
