Arizona State University researchers and Tempe-based Kinetic Muscles, Inc., have developed a robotic arm to help stroke survivors regain the ability to perform basic tasks, such as reaching for objects or feeding themselves. The rehabilitative device aids in task-oriented repetitive therapy, and the hope is that it will provide a cost-effective alternative to traditional therapy. This would enable a wider population to regain maximum motor function.
The research team is led by Jiping He, Ph.D., of the Biodesign Institute at Arizona State University. Dr. He* directs the Institute’s Center for Neural Interface Design and is a professor of bioengineering at ASU’s Fulton School of Engineering. Dr. He will present a paper on the design and evaluation of the robotic arm this summer at the 9th International Conference on Rehabilitation Robotics in Chicago on June 28-July 1.
Dubbed "RUPERT," for Robotic Upper Extremity Repetitive Therapy, Kinetic Muscles, Inc. is producing the prototypes for the project, which is funded by the National Institutes of Health. Kinetic Muscles currently has a device for hand rehabilitation in stroke survivors on the market.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
