Telomeres are one of the keys to aging. We’ve known this for decades, and the scientists who first figured it out won the Nobel Prize in 2009. (One of them was my former colleague at Johns Hopkins ...

Forbes contributors publish independent expert analyses and insights. I'm an American writer working in fiction and nonfiction. By 1990, scientists knew that telomeres are repetitive DNA sequences ...

Scientists have discovered that when telomeres become very short, they communicate with mitochondria, the cell's powerhouses. This communication triggers a complex set of signaling pathways and ...

Researchers introduce the 'Telomouse'. By making a subtle genetic alteration in standard lab mice, they've made the mouse telomeres, which protect the chromosome ends, more closely resemble those in ...

Telomeres are the structures that protect the ends of chromosomes. The ability of tumor cells to continue dividing indefinitely, as if they were immortal, depends on telomeres When 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 ...

One protein appears to play an integral role in protecting telomeres, and possibly preventing cancerous growth, according to a study published this week in Science. Chromosomes with fluorescently ...

A population-based study in Northern Sweden challenges assumptions about pollution and cellular aging, uncovering an unexpected signal of longer telomeres in patients with dementia that warrants ...

To stay young, you have to keep your cells young, and what dictates a cell’s age is its DNA. Too many cycles of dividing can trigger the aging process, until eventually the cell peters out and stops ...

Transposons, or "jumping genes" – DNA segments that can move from one part of the genome to another – are key to bacterial evolution and the development of antibiotic resistance. Cornell University ...
