Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance ...

It’s been 16 years since scientists first coaxed skin cells back into their embryonic state, a development that made it possible to sidestep the thorny ethical dilemmas around sourcing human stem ...

Researchers have discovered a mechanism behind the yo-yo effect: fat cells have a memory that is based on epigenetics. Researchers at ETH Zurich have discovered a mechanism behind the yo-yo effect: ...

Obesity rates are increasing in the United States and around the world, and the condition has been linked to increases in the risks of a wide range of health disorders, including diabetes and ...

Why do some people remain healthy through childhood yet become more vulnerable to brain disorders such as dementia later in life? A KAIST (President Kwang Hyung Lee) -led team has uncovered a key part ...

The immune system is one of the most complex parts of our body. It keeps us healthy by getting rid of parasites, viruses or bacteria, and by destroying damaged or cancer cells. One of its most ...
