Split hand syndrome is a potential sign of amyotrophic lateral sclerosis (ALS). This means that some of the muscles in the hand are weak and thin (atrophied), while others are less affected.

The Peg Restrained Intrinsic Muscle Evaluator (PRIME) enables more-accurate hand strength evaluation than methods that are currently available. (Image courtesy of Rice University.) A senior project ...

In a remarkable fusion of biology and technology, researchers from the University of Tokyo and Waseda University have developed a groundbreaking biohybrid robotic hand that utilizes lab-grown human ...

A biohybrid hand which can move objects and do a scissor gesture has been created. The researchers used thin strings of lab-grown muscle tissue bundled into sushilike rolls to give the fingers enough ...
