A strange gamma-ray glow at the center of the Milky Way has long sparked debate over whether it comes from hidden neutron stars or elusive dark matter. By applying machine learning to more than a million simulated observations, researchers included . ...

Scientists have solved a long-standing mystery by discovering the missing genetic ingredient that helps melanoma cells become effectively immortal. The breakthrough could open the door to new treatments aimed at disrupting one of cancer's most ...

Tiny, tooth-sized fossils have just reshaped the story of our deepest ancestry. Paleontologists have discovered the southernmost remains ever found of Purgatorius--the earliest-known relative of all primates, including humans--in Colorado's Denver .. ...

Researchers have uncovered an unexpected antiviral defense system in sea anemones that works very differently from the one humans use. The discovery suggests evolution developed multiple ways to combat viruses, challenging long-held ideas about how . ...

A Colorado research team has created experimental osteoarthritis treatments that appear to regenerate damaged joints rather than just relieve pain. In animal studies, a single injection restored arthritic joints to a healthy state within weeks, while ...

A common brain protein may be giving Alzheimer's disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones. By blocking these harmful protein packages before they reach new cells, researchers believe it . ...

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 ...

Scientists have finally confirmed the origin of the mysterious Silverpit Crater beneath the North Sea. New evidence shows that an asteroid about 160 meters wide struck the seabed roughly 43 to 46 million years ago. The impact triggered a tsunami more ...
