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.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
