Completing a daily crossword and enjoying a range of activities and interests has long been accepted as a recipe for maintaining a healthy brain in older age, but the reasons for this have never been clear. Now, scientists at the University of Edinburgh are seeking to identify brains survival genes which lie dormant in unused brain cells, but are re-awakened in active brain cells. These awakened genes make the brain cells live longer and resist traumas such as disease, stroke and the effects of drugs, and are also critical to brain development in unborn babies.
Their findings could lead to the development of smarter drugs or gene therapies to halt the progress of neurological diseases like Alzheimers and Parkinsons disease and may also explain, scientifically, the benefits to the brain of maintaining an intellectually and physically stimulating lifestyle in later years.
Dr Giles Hardingham of the Centre for Neuroscience Research at the University of Edinburgh said: "When brain cells are highly stimulated, many unused genes are suddenly reactivated. We have found that a group of these genes can make the active brain cells far healthier than lazy, inactive cells, and more likely to live a long life. These findings also have implications at the other end of life, where maternal drug taking and drinking can cause these survival genes to be turned off in the brain of unborn babies."

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...
