Scientists have successfully conducted the first clinical trial giving xenon gas to patients undergoing coronary artery bypass grafting in order to safeguard against postoperative brain damage that can occur following this procedure.
Research published in Anesthesiology shows how the team safely gave xenon to 12 patients undergoing coronary artery bypass grafting while on cardiopulmonary artery bypass, a step which could eventually lead to new treatments for people suffering from illnesses that damage nerve cells, such as strokes, and brain and spinal cord injuries.
Earlier preclinical work by the team showed that xenon was effective as a neuroprotectant, stopping processes present during strokes or brain and spinal cord injuries that would damage nerve cells. They found that xenon was capable of blocking the effects of a particular type of glutamate receptor, the same receptor implicated in the pathway that leads to nerve cell death.

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.

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...
