Scientists have discovered that wildfires release far more air-polluting gases than previously estimated. Many of these hidden emissions can transform into fine particles that are dangerous to breathe. The study shows wildfire pollution rivals human ...

Teens who sleep in on weekends may be giving their mental health a boost. A new study found that young people who made up for lost weekday sleep had a significantly lower risk of depression. While consistent sleep is still best, weekend catch-up ...

Dogs began diversifying thousands of years earlier than previously believed, with clear differences in size and shape appearing over 11,000 years ago. A massive global analysis of ancient skulls shows that early dogs were already adapting to ...

Earthquakes happen daily, sometimes with devastating consequences, yet predicting them remains out of reach. What scientists can do is map the hidden layers beneath the surface that control how strongly the ground shakes. A new approach speeds up ...

A familiar mouth bacterium best known for causing cavities may also be quietly influencing the brain. Scientists found that when this microbe settles in the gut, it produces compounds that can travel through the bloodstream and harm neurons involved ...

Researchers discovered that a poison frog species described decades ago was based on a mix-up involving the wrong museum specimen. The frog tied to the official species name turned out to be brown, not the colorful animal shown in the original photo. ...

A distant pulsar's radio signal flickers as it passes through space, much like stars twinkle in Earth's atmosphere. By monitoring this effect for 10 months, researchers watched the pattern slowly evolve as gas, Earth, and the pulsar all moved. Those ...

Living cells pay a hidden energy price not just to run chemical reactions, but to keep them on track and block all the alternatives. A new thermodynamic framework makes it possible to calculate these overlooked costs and compare different metabolic . ...

Researchers studying Caribbean whales and orcas have discovered two new viruses not previously observed in these animals. The viruses were found using advanced genetic sequencing of archived samples, revealing a previously invisible layer of marine . ...

Researchers at USF Health have discovered a new way opioid receptors can work that may lead to safer pain medications. Their findings show that certain experimental compounds can amplify pain relief without intensifying dangerous side effects like .. ...
