A model for ageing

Life is short, especially for the killifish, Nothobranchius furzeri: It lives for only a few months and then its time is up. During that short lifespan it passes through every phase of life from larva to venerable old fish. ...

Scientists find a key to maintaining our DNA

DNA contains all of the genetic instructions that make us who we are, and maintaining the integrity of our DNA over the course of a lifetime is a critical, yet complex part of the aging process. In an important, albeit early ...

Simulations open a new way to reverse cell aging

Research findings by a KAIST team provide insight into the complex mechanism of cellular senescence and present a potential therapeutic strategy for reducing age-related diseases associated with the accumulation of senescent ...

Newly discovered lipid prevents cell death

Programmed cell death is an important tool that an organism uses to keep itself healthy. When a cell does not function as it should, various stress reactions are activated. The goal of these reactions is to restore the original ...

Oxidative stress: Less harmful than suspected?

Arterial calcification and coronary heart disease, neurodegenerative diseases such as Parkinson's and Alzheimer's, cancer and even the aging process itself are suspected to be partially caused or accelerated by oxidative ...

New study takes a high-level look at Nazca boobies' breeding

Nazca boobies can live to 28 years of age, but in their late teens, their ability to raise chicks declines substantially. Why their breeding drops in old age has plagued Wake Forest University Professor of Biology David Anderson ...
