Anyone who made it to high school biology has learned about mitosis, or cell division. One cell divides into two, two into four and so forth in a process designed to pass on exact copies of the DNA in chromosomes to daughter cells. New research, by a University of Georgia team, shows how the genes that control this process are regulated.
The study is important for cancer research because the regulation of cell division goes awry in tumors and normal cell growth and behavior are lost. Understanding how normal cell division is regulated will allow scientists to identify potential targets for cancer therapeutics, said Stephen Dalton, the molecular geneticist who led the UGA team.
"This is fundamental molecular cancer research," Dalton said. "One major problem in cancer is mis-segregation, [when the cells] ability to equally divide chromosomes is lost. One [daughter] cell might get too much genetic information and the other too little.

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...
