How dormant bacteria come back to life

Solving a riddle that has confounded biologists since bacterial spores—inert, sleeping bacteria— were first described more than 150 years ago, researchers at Harvard Medical School have discovered a new kind of cellular ...

Scientists slow aging by engineering longevity in cells

Human lifespan is related to the aging of our individual cells. Three years ago a group of University of California San Diego researchers deciphered essential mechanisms behind the aging process. After identifying two distinct ...

A fast and efficient method for detecting microRNAs

In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs (miRNAs), which are now ...

New fluorescent dyes help illuminate microscopic life

Inspired by the mechanism behind light-sensitive sunglasses, a team led by a North Carolina State University researcher invented a family of fluorescent dyes to illuminate biological processes at a very small scale—comparable ...

Researchers find evolutionary support for induced defenses

Graduate student Reese Martin and his doctoral advisor, Ann Tate, assistant professor of biological sciences, used theoretical modeling to identify a potential relationship between genetic pleiotropy and the evolution of ...
