Also protects against bone loss from aging or lack of estrogen
Leaping tall buildings in a single bound may be out of the question, but the genetically engineered "supermice" in Ormond MacDougalds laboratory at the University of Michigan Medical School are definitely stronger than average. With bone mass up to four times greater than ordinary mice, these research animals could hold the secret to new drugs for preventing or treating osteoporosis and other human diseases.
The secret appears to be a secreted signaling protein called Wnt10b. Known to inhibit the development of adipose tissue in mice, Wnt10b also stimulates the growth of bone cells, according to a new study that will be published February 21 in the Online Early Edition of the Proceedings of the National Academy of Sciences. "High levels of Wnt10b expression in bone marrow directly increased bone mass and density in our experimental mice," says Ormond A. MacDougald, Ph.D., associate professor of molecular and integrative physiology in the U-M Medical School. "This is the first identification of a specific signaling protein in the Wnt family that regulates bone formation."

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...
