A group of scientists at The Scripps Research Institute (TSRI) and San Diego Supercomputer Center at the University of California at San Diego (UCSD) have used a powerful laser in combination with innovative quantum mechanical computations to measure the flexibility of mouse antibodies.
The new technique, described in an upcoming issue of the journal Proceedings of the National Academy of Sciences, is significant because protein flexibility is believed to play an important role in antibody-antigen recognition, one of the fundamental events in the human immune system.
"This is the first time anybody has ever gone into a protein and experimentally measured the frequency of protein vibrations in response to an applied force," says Floyd Romesberg, assistant professor in the Department of Chemistry at The Scripps Research Institute, who led the study.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
