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.

Watching molecules 'dance' in real time

(Phys.org) —A new technique which traps light at the nanoscale to enable real-time monitoring of individual molecules bending and flexing may aid in our understanding of how changes within a cell can lead to diseases such ...
