Mitochondria can lose power like batteries, but they can potentially be regenerated—a promising development than can be used ...

Tiny structures inside your cells keep your body alive by turning food into fuel. These structures, called mitochondria, ...

Retinoic acid, the active state of Vitamin A, appears to regulate how stem cells enter and exit a transient state central to their role in wound repair. Retinoic acid, the active state of Vitamin A, ...

When injured, cells have well-regulated responses to promote healing. These include a long-studied self-destruction process that cleans up dead and damaged cells as well as a more recently identified ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

The field of immunology of ageing is rapidly evolving, with T cells playing a pivotal role in maintaining immune competence and overall organismal ...

In a recent study published in the journal Nature, researchers found that the recruitment of neurons to memory circuits is preceded by a cascade of molecular events induced during learning, which ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Researchers at the University of Birmingham have made significant strides in understanding two key DNA repair pathways—offering much-needed clarity to an area of molecular biology that has long ...
