The parts of the genetic make-up that are thought to determine an individual’s maximum possible longevity, so-called telomeres, are inherited from the father but not the mother. This is shown by a research team at Umeå University in the coming issue of the U.S. scientific journal Proceedings of the National Academy of Sciences.
Telomeres are genetic material with repetitive content at the ends of DNA, and their main function is believed to be to protect the rest of the genetic material from degradation. Telomeres are shortened each time a cell divides, which in broad terms means that the longer a cell’s telomeres are, the longer the individual can live, in theory. A person’s telomeres are shortened with age, which the findings of the study indeed show: telomeres were shortened by an average of 21 nitrogen base pairs per year in the subjects studied.
The study, soon to appear in the U.S. scientific journal PNAS, Proceedings of the National Academy of Sciences, was carried out on 132 healthy subjects in 49 different families with no close kinship to each other in northern Sweden. The subjects consisted of fathers and mothers (mean age 66 years) and their daughters and sons (mean age 37 years). Blood samples were taken, and mononuclear immune cells were culled.

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...
