Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from ...

Our genome is organized into chromosomes, which are shaped like little X's. Every time a cell divides, the genome has to be replicated, and there are protective caps called telomeres on the ends of ...

Tumors are stressful places for cancer-fighting immune cells. Low oxygen, high acid levels, and other stressors put strain on mitochondria, the cell's energy factories, leading to T cell exhaustion ...

As people age, caps called telomeres on the ends of their chromosomes shrink. The observation has led some scientists to argue the shortening is... Healthful Living May Lengthen Telomeres And ...

A day in the life of DNA can be rough. It gets yanked across a dividing cell, zapped by radiation, and assaulted by chemicals. Luckily, cells have developed a complex set of repair mechanisms to ...

A research group from the National Cancer Research Center (CNIO) has found that an alteration in the POT1 gene prevents lung tissue from regenerating, which over time makes breathing difficult. The ...

New research in The American Journal of Clinical Nutrition suggests vitamin D supplements may slow aging by preserving telomere length. Experts explain how vitamin D reduces inflammation, supports ...

Researchers studying a Swedish aging cohort found no overall link between air pollution and telomere shortening, a key marker ...
