We all know that a viral infection can be developed extremely quickly, but in fact its even more dramatic than that - the process is literally explosive.
The pressure inside a virus is 40 atmospheres, and it is just waiting for an opportunity to blow up. The virus is like a living DNA cannon. How this cannon functions has been mapped by Dr. Alex Evilevitch at the Department of Biochemistry at Lund University in Sweden. This is knowledge that will have applications in gene therapy, drug development, nanotechnology and the treatment of infections. This involves a new type of virus research that is based more on physics than biochemistry. Perhaps it could be called virus biophysics. Alex Evilevitch took his doctorate at Lund in physical chemistry and worked for a few years at UCLA.
"There I met Professor William Gelbart, who predicted on theoretical grounds that the pressure in a bacteriophage - a virus that attacks bacteria must be 40 atmospheres," explains Alex Evilevitch. "This roughly corresponds to the pressure at a depth of 400 meters under the sea. Thats twenty times more than the pressure in a car tire and ten times more than the pressure in an unopened bottle of champagne. Using measurements, I was able to confirm that Professor Gelbarts prediction was accurate."

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...
