In its latest Perspectives in General Physiology series, the Journal of General Physiology (JGP) offers an in-depth look at several of these methods and the advantages of each as applied to membrane proteins, with special focus on ion channels. The Perspectives appear in the June issue (www.jgp.org).
The main focus of computational biology is to develop mathematical modeling and computational techniques to better analyze biological systems. As guest editor Benoit Roux (University of Chicago) explains, no single method can provide researchers with all the levels of description needed to fully examine every relevant lengthscale and timescale of a particular physiological process. However, the four Perspectives presented in this issue illustrate how various methods can be used to achieve different goals.
The Perspectives include: Denis Bucher and Ursula Rothlisberger (Ecole Polytechnique Fédérale de Lausanne) present ab initio (first-principles) simulations; David Shaw and colleagues (Columbia University) examine the all-atom molecular dynamics (MD) method; Ivet Bahar (University of Pittsburgh) shows how important insights can be obtained from "course-grained" (CG) models; and Jonathan Silva and Yoram Rudy (University of Chicago) examine a strategy using a small number of simplified "states" to represent a complex system.
The purpose of the Perspectives in General Physiology series is to provide an ongoing forum where scientific questions or controversies can be discussed by experts in an open manner.

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...
