Scientists who developed the first yeast model of Parkinsons disease (PD) have been able to describe the mechanisms of an important genes role in the disease. Tiago Fleming Outeiro, Ph.D., and Susan Lindquist, Ph.D., of the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts, studied the genes actions under normal conditions and under abnormal conditions to learn how and when the genes product, alpha-synuclein, becomes harmful to surrounding cells. The scientists created a yeast model that expresses the alpha-synuclein gene, which has been implicated in Parkinsons disease (PD). Yeast models are often used in the study of genetic diseases because they offer researchers a simple system that allows them to clarify how genes work.
The National Institute of Neurological Disorders and Stroke, part of the National Institutes of Health, funded the study, which appears in the December 5, 2003, issue of Science.
The alpha-synuclein protein, which is found broadly in the brain, has been implicated in several neurodegenerative disorders. Sometimes a mutation or a misfolding of the protein causes the problems; other times there are too many copies of the normal gene. A study earlier this year reported that patients with a rare familial form of PD had too many normal copies of the alpha-synuclein gene, which resulted in a buildup of protein inside brain cells, causing the symptoms of PD.

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...
