Scientists at the University of Sheffield have played a major role in sequencing the chicken genome, published in Nature and Genome Research on Thursday 9 December. The chicken is the first farm animal to be successfully sequenced, as well as being the first bird.
The Sheffield team were responsible for determining the sequences of messenger RNAs, which have allowed an international team of scientists to analyse the chicken genome sequence and identify most chicken genes.
The team have also contributed to an analysis of the genetic differences in three types of chicken, which has implications for the food industry. They examined the genomic sequence for a meat producing chicken (broiler), an egg producing chicken (layer), an ornamental chicken called the Silkie and the genome sequence for an ancestral chicken called the red jungle fowl. This research found that, despite many years of intensive breeding, modern food production chickens retain much of the genetic diversity found in their wild ancestors.

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...
