Why is it that when you go on holiday some members of your family always seem to get bitten more than others? Researchers supported by the Biotechnology and Biological Sciences Research Council (BBSRC) think they may have found the answer and their work could lead to new types of insect repellent.
James Logan, a research student at the BBSRC-sponsored institute Rothamsted Research in Hertfordshire, has found that some people give off "masking" odours that prevent mosquitoes from finding them. His research builds on earlier studies on cattle at Rothamsted Research, led by Professor John Pickett, which showed that the number of flies on a herd depended on certain cows being present. The scientists found these key unattractive individuals gave out different chemical signals from the other cows. When these individuals were moved to another field the number of flies afflicting the herd increased.
James, working in collaboration with Professor Jenny Mordue at the University of Aberdeen, tested the behavioural reaction of yellow fever mosquitoes to the odour of the volunteers. James said: "The mosquitoes were placed into a y-shaped tube and given the choice of moving upwind down either branch. The air flowing down one branch was laced with odour from the volunteers hands."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
