Scientists at UCLA discovered a surprising reason aging muscles heal more slowly. In older muscle stem cells, a protein called NDRG1 builds up and acts like a brake, slowing the cells' ability to jump into repair mode after injury. But there's a ...

Scientists have discovered that a common type of stroke may have a very different cause than doctors once thought. Instead of fatty plaque clogging arteries, the strongest link was found with enlarged and damaged blood vessels deep within the brain. ...

Bumble bees astonished researchers by inventing a new way to reach a hidden reward, despite never being taught the trick. The discovery adds to growing evidence that these tiny insects are far smarter and more adaptable than once believed.

A protein called "Mitch" may hold the key to a new generation of obesity treatments. Researchers found that disabling it in human cells boosts fat burning, increases energy use, and makes it harder for new fat cells to develop. The findings help ...

A new spray-on powder developed by KAIST can stop life-threatening bleeding in about one second by instantly forming a strong gel over a wound. It works on deep and irregular injuries where conventional hemostatic products often struggle and remains ...

A massive national study found that nearly half of Americans with kidney failure who are referred for a transplant never even begin the evaluation process, and only 19% make it onto the transplant waitlist. Researchers discovered that factors such as ...

A surprising discovery is overturning a long-held assumption about how the brain's movement center works. Researchers found that two key cerebellar cell types--thought to be tightly linked--often don't behave in predictable ways, even though one ...

What if Sigmund Freud was onto something that modern neuroscience is only now beginning to explain? A new paper argues that today's leading theory of the brain--as a prediction machine constantly anticipating the world--closely mirrors ideas ...

Could something as simple as vitamin C help support a healthier aging brain? In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and weaker ...

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 ...
