A study in the April issue (currently available online) of Nature Genetics establishes a model that may take scientists closer to understanding how cells in the human body determine their own fate.
Researchers, led by Anthony Firulli, Ph.D., associate professor of pediatrics and of medical and molecular genetics at the Indiana University School of Medicine, investigated the interaction of proteins responsible for Saethre-Chotzen Syndrome, a rare genetic disorder associated with limb abnormalities including webbed fingers and other developmental defects.
In the study, Dr. Firulli and colleagues studied how two proteins, Twist1 and Hand2, which are antagonists, couple to determine the number of digits on a hand, paw or wing, and whether these digits are webbed or not. In addition to limb abnormalities, these proteins are associated with cardiac and placental tissue defects. Twist1 mutations are encountered at high frequency in patients with Saethre-Chotzen Syndrome.

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
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
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...
