Forbes contributors publish independent expert analyses and insights. Telomeres, the protective caps at the ends of our chromosomes, act much like the plastic tips of shoelaces, preventing our DNA ...

Some say that the telomere test might not tell people much that cannot be learned in other ways. “You can pretty much look at people and determine their biological age,” said Michael West, who founded ...

The University of Wisconsin’s Lim Lab has identified the cause of chromosome instability associated with a range of genetic diseases. Their findings, published in Science, attributed dysfunction in a ...

Small plastic or metal bits at the end of shoelaces, known as aglets, prevent laces from unraveling and protect them from wear and tear. Similarly, chromosomes are capped by telomeres—specialized ...

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 ...
