Breaking up families can be sad, but in a new method for selecting passive livestock animals, that’s a main ingredient for better long-term productivity, according to a Purdue University geneticist.

Using his new breeding approach of picking individual animals that are passive in their behavior and housing them together, breeders can achieve higher long-term productivity.

The new breeding program, designed to get the best out of the animals, is the first major advance in classical breeding in 20 years, said William Muir of the Purdue Department of Animal Sciences. By picking less aggressive individual animals from a broad range of families, the same breeding program can be used for hundreds of generations.
The new program enables breeders to have optimal improvement in productivity while minimizing the health risks associated with inbreeding, he said. At the same time, the program overcomes competition among animals for resources that often means less aggressive animals suffer from lack of nutrition and increased injury. In a group composed of both aggressive and passive animals, even those at the top of the pecking order are harmed from overeating, which wastes food because their bodies can’t properly utilize the nutrition.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
