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 ...

Researchers have identified a common supplement that can slow aging. It may even be in your medicine cabinet already. Science ...

New research from the University of Wisconsin–Madison reveals that dysfunction in a protein essential to maintaining ...

A study reveals that a protein called RPA is essential for maintaining chromosome stability by stimulating telomerase. New findings from the-Madison suggest that problems with a key protein that helps ...

Much the way the caps on the ends of a shoelace prevent it from fraying, telomeres — regions of repetitive DNA sequences and a protein structure — protect the tips of chromosomes from damage. Every ...

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 ...

A study found that daily vitamin D supplements helped slow telomere shortening—the cellular process linked to aging and ...

Short telomeres might lead to increased risk of Alzheimer’s disease, but observational analyses have been inconclusive and potentially confounded by the strong association of both telomere length and ...

Q I have been reading more and more about telomeres. I have seen advertisements for supplements sold with the claim to lengthen telomeres. Is there any real science behind the supplement claims? — G.F ...
