Mayo Clinic researchers are the first to identify an interaction between two cellular proteins -- Skp2 and FOXO1 -- that is important for the growth and survival of cancer cells. Researchers also show that this interaction can be chemically reversed to stop cancer tumor growth -- a strategy that may lead to new and better cancer treatments.
Their report appears as an electronic advance article of PNAS, the Proceedings of the National Academy of Sciences ( http://www.pnas.org/cgi/reprint/102/5/1649). The research was performed on human cells in the laboratory and was found effective against human cancer cells. Researchers say it will be at least a year before the discovery can be applied in a human clinical trial.
The researchers noted that high levels of Skp2 were associated with low levels of FOXO1 in many human cancer cells, including prostate cancer -- and then combined the lines of evidence outlined above to design experiments to answer the specific question: Do elevated levels of Skp2 drive down and disable FOXO1, thus resulting in loss of its tumor suppression ability? The answer is yes.

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...
