Aging: What underlies the mitochondrial stress response

Scientists at EPFL have discovered certain enzymes that play a central role in the stress responses that defend mitochondria from stress, and promote health and longevity.

Study provides whole-system view of plant cold stress

When temperatures drop, plants can't bundle up. Stuck outside, exposed, plants instead undergo a series of biochemical changes that protect cells from damage. Scientists have described these changes and identified some of ...

Gene network illuminates stress, mutation and adaptation responses

For much of her professional life, Dr. Susan Rosenberg has studied the puzzling response of bacteria to stress and the mutations that result. In the current issue of the journal Science, she puts together the pieces of that ...

A new role for cytokinin plant hormones

When plants, including crops, are exposed to environmental stresses such as drought or high salinity, abscisic acid (ABA), a stress-responsive hormone is synthesized to induce a protective response. At the same time, the ...

Biologists identify a new clue into cellular aging

The ability to combat some age-related diseases, such as cancer and diabetes, may rest with scientists unlocking clues about the molecular and cellular processes governing aging. The underlying theory is that if the healthy ...
