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

Scientists have discovered that a protein linked to cell death is secretly driving the aging of blood stem cells in a completely different way. Instead of killing the cells, it damages their ...

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

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 ...

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 ...

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

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

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

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 ...
