Probiotics are not always the right approach.
Millions of women around the world have probably used yoghurt as a folk remedy to prevent thrush while taking antibiotics. A Melbourne GP and PhD student has proven that Lactobacillus acidophilus, a key bacterium in yoghurt, was not effective in the prevention of thrush (‘vulvovaginitis’) after antibiotics. Her findings were published recently in the eminent British Medical Journal (BMJ). “It’s a reminder that all medicines, even natural ones need to be tested,” says Dr Pirotta.
235 Melbourne women took probiotic (containing lactobacillus bacteria) or placebo preparations orally or vaginally until four days after completion of their antibiotic course. They recorded any symptoms and provided vaginal swabs for analysis. The results were so clear cut that the trial was cut short on ethical grounds.

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...
