In APL Materials, researchers have developed a bioelectrical sensor that is convenient and low-cost. The sensor measures electromyography signals that are generated in muscles when they contract and are useful for studying muscle fatigue and recovery, and they have the potential to inform diagnosis and treatment of neuromuscular diseases. The biosensor, made of silver paste with a layer of gold nanoparticles on top, is directly integrated onto a piece of clothing. The result was a detector that was both conductive and nonirritating to the skin.
Wild orangutans are known for their ability to survive food shortages, but scientists have made a surprising finding that highlights the need to protect the habitat of these critically endangered primates, which face rapid habitat destruction and threats linked to climate change. Scientists found that the muscle mass of orangutans on the island of Borneo in Southeast Asia was significantly lower when less fruit was available. That’s remarkable because orangutans are thought to be especially good at storing and using fat for energy, according a Rutgers-led study in the journal Scientific Reports.
A research team led by Associate Professor Alfredo Franco-Obregón from the National University of Singapore’s Institute for Health Innovation and Technology has shown how a molecule found in muscles responds to weak magnetic fields. This responsiveness could be used to stimulate muscle recovery.

Researchers studying the mystery of why some weightlifters’ muscles grow much more quickly than others’ have found new answers through a novel experiment in which subjects worked out one leg and immobilized the other.
