How Anglers Are Learning To Save Fish That Get 'The Bends'
Millions of deep-water fish die every year because of barotrauma, a condition divers know as "the bends." But scientists say descending devices can help fish survive a trip to the surface.

How Thoroughbreds Convert Air Into Blazing Speed
There are sprinters and there are distance runners, but the thoroughbreds charging down the track this month at the Kentucky Derby (sometimes called the fastest two minutes in sport) need to be both. The race stretches a grueling mile and a quarter, so those horses have to be machines that convert air into speed.

Golden Arches: Human Feet More Flexible Than We Thought

X-ray tomography on a living frog embryo 
Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones. Alternatively, X-rays can also image soft tissues throughout early embryonic development of vertebrates. Related to this, a new X-ray method was presented recently in a Nature article published by a German-American-Russian research team led by KIT.

Researchers identify key cellular organelle involved in gene silencing
RNA molecules, made from DNA, are best known for their role in protein production. MicroRNAs (miRNAs), however, are short (~22) nucleotide RNA sequences found in plants and animals that do not encode proteins but act in gene regulation and, in the process, impact almost all biological processes — from development to physiology to stress response.

Sometimes you just can't resist a tiny piece of chocolate cake. Even the most health-conscious eaters find themselves indulging in junk foods from time to time. New research by scientists at the University of Massachusetts Medical School (UMMS) raises the striking possibility that even small amounts of these occasional indulgences may produce significant changes in gene expression
