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.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
Elpasolite is a glassy, transparent, shiny and soft mineral with a cubic crystal structure. First discovered in El Paso County (Colorado, USA), it can also be...
For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility.
In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive...
