Scientists have pinpointed and described unusual subtypes of fat cells that may help scientists explain why gut fat is linked to poor health. The research could open up new avenues for medical treatments.

A man who should have developed early-onset Alzheimer's disease due to a genetic mutation is still symptom-free in his 70s. Scientists are trying to understand why.

People with aphantasia still generate brain activity when attempting to visualize, but that image may be getting lost in translation, a new study suggests.

Fathers exposed to high stress in childhood had different epigenetic markers that may affect their offspring, though more research is needed.

A study using Swedish patient data found anti-obesity drugs were linked with fewer hospitalizations related to alcohol use, adding to a body of work suggesting these drugs could potentially be used to manage addiction.

Most people who lose weight through dieting will see it creep back up, leading to a cycle of "yo-yo dieting" that's hard on the body. A new study suggests fat cells keep a memory of previous weight gain, which may help to explain why this happens.

Stress can shape how memories are formed, a study in mice suggests. The findings could point the way to future treatments for PTSD and anxiety.
