New study may have implications for millions in search of the elusive “good night’s sleep”
In movies and novels alike, much is made of the stage of sleep known as rapid eye movement (REM), since this is the phase of slumber in which dreams (good, bad, exotic) occur. Among the medical community, there is an increased appreciation for what is called “slow-wave” sleep, (also known as deep or delta-wave sleep), because this fourth stage of sleep can be difficult to attain. If one is awakened during the first three stages of sleep, they must repeat these stages again before reaching fourth stage or “delta-wave,” sleep.
Once this latter stage is reached, muscles are relaxed, blood pressure drops, and the pulse and breathing are slower. According to the Sleep Research Center, other benefits to the body are accrued during slow-wave sleep, including: an increase of blood supply to the body; a decrease in body temperature thus preserving energy; a lowering of metabolic activity enabling tissue repair and growth; an increase of natural immune-system modulators; and a period in which the growth hormone secretions reach their peak, thus stimulating body growth and development.

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...
