Breakthrough in Monte Carlo computer simulations
Researchers develop new algorithm to effectively study long-range interacting systems. Researchers at the University of Leipzig have developed an extremely efficient method for studying systems with long-range interactions that have been very puzzling to experts until now. These systems can be gases or even solid materials such as magnets, whose atoms interact not only with their neighbors, but much more widely.

A new perspective in protein research
A new perspective in protein research
The ordered areas of proteins are readily studied. Consequently, a great deal is known about the role of these areas in the biological function of the respective proteins. However, an international research team led by biochemist Ute Hellmich has shown that disordered areas are also pivotal. Their comprehensive examination of the disordered area of a receptor channel protein has been published in the renowned scientific journal "Nature Communications." The group demonstrated through eleven different methods how this area influences the function of the entire protein.
