A little stress is good for cellular health and longevity

Northwestern University molecular bioscientists have discovered that a little stress can be good for cellular health. The findings will help researchers better understand the molecular mechanisms that drive aging and risk ...

Researchers report innovative optical tissue imaging method

A UK-wide research team, led by the University of St Andrews, has developed an innovative new way to optically image through tissue, which could allow for a more detailed understanding and diagnosis of the early stages of ...

Cells in fish's spinal discs repair themselves

Duke researchers have discovered a unique repair mechanism in the developing backbone of zebrafish that could give insight into why spinal discs of longer-lived organisms like humans degenerate with age.

Nano-SPEARs gently measure electrical signals in small animals

Microscopic probes developed at Rice University have simplified the process of measuring electrical activity in individual cells of small living animals. The technique allows a single animal like a worm to be tested again ...

Scientists find key to vitamin A metabolism

Researchers at Case Western Reserve University School of Medicine have uncovered the mechanism that enables the enzyme Lecithin: retinol acyltransferase (LRAT) to store vitamin A—a process that is indispensable for vision.
