A step towards understanding cell mutations that cause a variety of human diseases, particularly in children -including that which brings about premature aging and early death - has been taken by researchers at the Hebrew University of Jerusalem Silberman Institute of Life Sciences and the John Hopkins University School of Medicine.
The scientists have focused their research on a study of induced mutations in the nuclear envelope of cells from the tiny C. elegans worm. Their aim is to thus provide clues towards a better understanding of mutations in proteins of the envelope of the cell nucleus in humans.
Such mutations, particularly in lamin (nuclear envelope) proteins A and C, cause many different diseases, including Hutchison Gilford progeria syndrome. Children with this disease develop premature aging and die usually before the age of 13. Other diseases brought about by these mutations include a form of muscular dystrophy, cardiomyopathy (a weakening of the heart muscle), and various other forms of irregular or retarded growth in childhood.

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...

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...
