Critical connections that neurons form in the brain during development turn out to rely on common but overlooked cells, called glia. These cells were known to support the neurons in adults, but had never been fingered as players in forming the connections between neurons, known as synapses.
The Stanford University School of Medicine researchers who conducted the work, led by Ben Barres, MD, PhD, professor of neurobiology, also discovered two of the proteins made by glial cells that signal synapse formation. This study, published in the Feb. 11 issue of Cell, could help researchers understand diseases such as epilepsy and addiction in which too many synapses form.
"We knew glia had a close relationship with neurons," Barres said. "We never thought the synapses would entirely fail to form without the glia." In fact, that relationship was considered so unlikely that the grant application was turned down six times because the work was considered too risky. The research was eventually funded by the National Institute on Drug Abuse, whose interest in the work stems from the possibility that new synapses are what keep recovered addicts craving drugs.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
