Five-year NIH-funded study will examine how early-life factors such as growth patterns and exposure to air pollution affect ...

"Telomeres are special (genetic) sequences found at the ends of chromosomes, which are very long DNA molecules. Telomeres are ...

Telomeres are often described as the protective caps of our chromosomes. Over time, telomeres get shorter, and this shortening has been linked to aging, infertility, and heart disease. For years, the ...

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 ...

A study found that daily vitamin D supplements helped slow telomere shortening—the cellular process linked to aging and disease. Researchers believe its anti-inflammatory effects may protect DNA.

Premature aging may be due to various factors, such as telomere shortening and a lack of cell division. Lifestyle habits such as eating a nutritious diet, being physically active, and getting enough ...
