Researchers at the University of Pennsylvania School of Medicine have demonstrated that star-shaped glial cells in the brain called astrocytes are directly involved in regulating communication between neurons. A central finding of the study is that astrocytes modulate the level of a signaling molecule called adenosine, which is thought to be important in controlling wake-to-sleep transitions and epileptic seizures.
"This finding may cause neuroscientists to radically alter their view of the role of astrocytes as merely supportive to one of actively communicating with and instructing neurons," states senior author Philip G. Haydon, PhD, Professor of Neuroscience. "Astrocytes are not just the kitchen cells of the brain, providing nutritional support, but instead also help the neurons talk to each other." Haydon and colleagues published their results in last weeks issue of Science.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
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...
