The genes that influence the risk of developing Alzheimers disease may vary over the course of an individuals lifetime, a new study by Duke University Medical Center researchers finds. The teams results revealed two chromosomal regions not previously known to influence Alzheimers disease: one linked to the disorder in families that first show symptoms early in life and another in families with very late onset of the disorders symptoms.
While earlier studies have identified genes that underlie early- versus late-onset Alzheimers disease, the new study is the first to indicate that distinct genes might also determine the very late onset of Alzheimers disease, in which symptoms first appear after the age of 80, said Duke Center for Human Genetics researcher William Scott, Ph.D., the studys first author.
The teams findings will appear in the November 2003 issue of The American Journal of Human Genetics. The research was supported by the National Institute on Aging and the Alzheimers Association. The study immediately follows another in which the Duke team identified a single gene that influences the age at onset of both Alzheimers and Parkinsons diseases.

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...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
