Novel method to accurately measure key marker of biological aging

Telomeres—the caps at the ends of chromosomes that protect our genetic materials from the brunt of cellular wear and tear—are known to shorten and fray over time. Lifestyle, diet and stress can exacerbate this process, ...

Study: Rapamycin has harmful effects when telomeres are short

In the past few decades, researchers discovered that the rate at which we age is strongly influenced by biochemical processes that, at least in animal models, can be controlled in the laboratory. Telomere shortening is one ...

Chromosome number changes in yeast

Researchers from Trinity College Dublin have uncovered the evolutionary mechanisms that have caused increases or decreases in the numbers of chromosomes in a group of yeast species during the last 100-150 million years. The ...

Noise may shorten sparrow lives, study finds

The noise of cars honking and zooming through the streets may shorten the lifespan of sparrows growing up near the clamour, scientists said Wednesday.

Position of telomeres in nucleus influences length

(PhysOrg.com) -- A study the latest issue of Nature Cell Biology sheds light on the mechanism controlling telomere length in budding yeast. In this publication, scientists from the Friedrich Miescher Institute for Biomedical ...
