Pressure sensors between thumb and index finger regulate the power of the artificial hand.

The pain of losing a body part is twofold, as patients not only suffer from wound pain. Often they are also affected by so called phantom pain. Unlike bodily wounds which will eventually heal, phantom pain often lasts for years and sometimes a lifetime.

Researchers are investigating new ways for developing a novel painkiller based on natural compounds found in the venom of scorpions.

Scorpion venom is notoriously poisonous — but it might be used as an alternative to dangerous and addictive painkillers like morphine, a Tel Aviv University researcher claims.

Clues To Reversing Aging Of Human Muscle Discovered

Young, healthy muscle (left column) appears pink and red. In contrast, the old muscle is marked by scarring and inflammation, as evidenced by the yellow and blue areas. This difference between old and young tissue occurs both in the muscle’s normal state and after two weeks of immobilization in a cast. Exercise after cast removal did not significantly improve old muscle regeneration; scarring and inflammation persisted, or worsened in many cases.

A study led by researchers at the University of California, Berkeley, has identified critical biochemical pathways linked to the aging of human muscle. By manipulating these pathways, the researchers were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself.

Aging Muscles: ‘Hard To Build, Easy To Lose’

090911103807-large

New research may explain the ongoing loss of muscle in older people, whose arms and legs become thinner as they age

Have you ever noticed that people have thinner arms and legs as they get older? As we age it becomes harder to keep our muscles healthy. They get smaller, which decreases strength and increases the likelihood of falls and fractures. New research is showing how this happens — and what to do about it.
