The brain as command center for bodily movement was too simple an idea, thought the Russian physiologist Nicolas Bernstein some 60 years ago. After studying human movements for years, Bernstein pointed out in 1940 that the great flexibility of the body, coupled with unexpected events in the world, meant that the nervous system had to prepare the body in advance for what might happen next.
If Bernstein were right, it would affect the design of prosthetic devices and biologically inspired robots.
Using computer technologies unavailable to their predecessor, researchers at Case Western Reserve University have provided direct evidence for Bernsteins hypothesis. Reporting on their findings in the Journal of Neuroscience are Hillel Chiel, professor of biology, neurosciences and biomedical engineering; Hui Ye, Chiels former graduate student who is currently a postdoctoral fellow at the Toronto Western Research Institute; and Dr. Douglas Morton, another former graduate student who is currently a radiologist at Premier Medical Imaging in Michigan.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
