Using math and physics to investigate mad cow disease (bovine spongiform encephalopathy or BSE) and similar diseases caused by infectious proteins called prions is the aim of research by physicists Daniel Cox, Rajiv Singh and colleagues at UC Davis. The researchers are using mathematical models to study issues such as the incubation time, prion "strains" and treatment or detection strategies.
Diseases such as BSE in cattle, Creutzfeld-Jakob disease in humans and chronic wasting disease in deer are all apparently caused by prions, misfolded versions of a normal brain protein. Similar diseases have been found in other animals including cats, mink and rodents, and prion-type proteins have even been found in yeast.
Prions seem to cause disease by triggering normal versions of the same protein to spontaneously fold up the wrong way, creating growing mats and tangles.

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...
