To address these concerns, Herman Suit and his colleagues Saveli Goldberg, Andrzej Niemeierko, Marek Ancukiewicz, Eric Hall, Michael Goitein, Winifed Wong and Harald Paganetti examined data on radiation-induced neoplastic transformation of mammalian cells in vitro and on the risk of an increase in cancer incidence after radiation exposure in mice, dogs, monkeys, the atomic bomb survivors, persons exposed occupationally, and patients treated with radiation.
The study appears in the January issue of the journal Radiation Research.
The authors found that there is great heterogeneity in the risk of radiation-associated cancer between species, strains of a species, and organs within a species. Currently, the heterogeneity between and within patient populations of virtually every parameter considered in risk estimation results in substantial uncertainty in quantification of a general risk factor.
One implication of their review is that reduced risks of secondary cancer should be achieved by any technique that achieves a dose reduction down to ~0.1 Gy (i.e., the dose to tissues distant from the target). Based on their study, they conclude that the proportionate gain should be greatest for dose decrement to less than 2 Gy.

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...
