Annabel Howard and Francois Omlin from the International Centre of Insect Physiology and Ecology in Nairobi, Kenya, introduced Nile tilapia (Oreochromis niloticus L.), to abandoned fishponds in western Kenya. The study, funded by the Government of Finland, BioVision Foundation (Switzerland) and the Toyota Environment Foundation, monitored pond life, comparing the restocked ponds with a control pond nearby.
After 15 weeks the fish reduced both Anopheles gambiae s.l. and Anopheles funestus, the region's primary malaria vectors, by over 94 percent. The fish also decimated three quarters of the culicine mosquito population.
The findings present a win-win situation for Kenyans, who can use the fish to limit mosquito populations and gain food and income from them too. "O. niloticus fish were so effective in reducing immature mosquito populations that there is likely to be a noticeable effect on the adult mosquito population in the area," Howard says. This control method is apparently sustainable, as the fish breed and provide a continuous population. The authors also point out other benefits in their article.
There are over 2000 pediatric malaria cases annually in the Kisii Central District where the authors carried out their research. Nile tilapia's predilection for mosquitoes has been known since 1917. However this is the first field data published detailing this species' use for mosquito control.

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...
