Scientists have developed a new ultra-light limb that can mimic the movement in a real hand better than any currently available. This research was presented today at the Institute of Physics conference Sensors and their Applications XIII which took place at the University of Greenwich, Kent, UK.
Every year 200 people in the UK lose their hands. Common causes include motorbike accidents and industrial incidents. Currently available prosthetic hands are either simple mimics that look like a hand but dont move or moving hands which have a simple single-motor grip.
The human hand has 27 bones and can make a huge number of complex movements and actions. Dr Paul Chappell, a medical physicist from the University of Southampton has designed a prototype hand that uses 6 sets of motors and gears so that each of the five fingers can move independently. This enables it to make movements and grip objects in the same way a real human hand does.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
