For decades, circular RNA was treated as little more than molecular background noise — stable fragments that accumulated in ...

As people grow older, their immune systems do not simply slow down, they often become locked into a simmering, self-perpetuating state of inflammation. Emerging work now suggests that aging immune ...

Aging and cancer are deeply intertwined: advancing age is the single largest risk factor for most malignancies, and many of the molecular processes that ...

Improvements in public health have allowed humankind to survive to older ages than ever before, but, for many people, these added golden years are not spent in good health. Aging is a natural part of ...

Researchers have identified an unexpected mechanism that links age-related stress to the decline of blood-forming stem cells.

Scientists found that compounds in coffee interact with a cell receptor that helps reduce stress and inflammation.

Scientists succeed in reversing liver damage by removing key aged cells, p21-TREM2, that cause inflammation and fat ...

During vaccination, the immune system is purposefully exposed to weakened, inactivated, or a component of pathogens so that the body can recognize their molecular structures in the future and mount a ...
