Cellular senescence is commonly defined as a state characterized by permanent cell cycle arrest in the absence of cell death, in which cells have altered function. While cellular senescence has been ...

A person’s body can age faster than the calendar suggests, and that gap may carry important clues about dementia risk. In a ...

The brain plays a big part in the aging process, and scientists think they’ve pinpointed the specific cells that control it. In a study of mice, researchers at the Allen Institute identified certain ...

Researchers develop IRISeq and EnrichSci to map cellular neighborhoods and analyze rare aging cells in the brain simultaneously.

In a recent study published in the journal Nature, researchers developed spatial aging clocks using single-cell transcriptomics to explore cell-type-specific interactions and their impact on brain ...

While much is mysterious about the aging process, change over time remains its cornerstone. The biological shifts that ...

Sedentary lifestyles and lack of physical activity can accelerate brain aging. Chronic stress and poor sleep negatively affect memory and brain health. Staying socially connected and eating a balanced ...

Aging may "erase" the epigenetic markers that control gene expression in the brain, and this may snowball to cause unintended consequences, a new mouse study suggests. Tiny chemical messages attached ...
