Two important questions face biologists studying the infectious proteins called prions: What stops prions that infect one species from infecting another species and what causes the invisible transmission barrier between species to fail sometimes?
In experiments with yeast prions reported in this weeks issue of Nature, Howard Hughes Medical Institute researchers have shown how point mutations in prions — which do not compromise their infectivity — can nevertheless cause prions to alter the specificity of the yeast strain that they infect.
According to the researchers, their findings point the way to studies that could begin to clarify the factors that determine whether a prion specific to cattle that causes bovine spongiform encephalopathy (BSE), or mad cow disease, might become infectious to humans.

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
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...
