University of Wisconsin-Madison biochemists have developed an approach that allows them to measure with unprecedented accuracy the strengths of hydrogen bonds in a protein. The scientists were then able to predict the function of different versions of the protein based on structural information, a novel outcome that was published recently in the Proceedings of the National Academy of Sciences.
Professor of biochemistry John Markley, along with a team that included graduate student I-Jin Lin, studied iron-sulfur proteins called rubredoxins that transfer energy in the form of electrons throughout living systems.
Rubredoxin is a key part of processes like photosynthesis and respiration, where energy is converted from one form to another.
"Variants of rubredoxin have evolved different sequences to transport electrons in the most efficient manner possible," Markley explains. "Different mechanisms have been put forward to explain this, and we wanted to understand how the proteins evolved to have different electron affinities."

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...
