Recording and classifying the behaviour of laboratory rodents is a vital part of a wide range of studies ranging from the discovery of new drugs and detection of harmful side-effects to the biological control of agricultural pests. Until now, it has been a lengthy and painstaking task, requiring human observers to judge, count and record. But a new computerised system developed with EUREKAs help has done away with the need for human observers, revolutionising the way labs work around the world.
One of the key issues in the biological control of agricultural pests is to find the right natural enemy for a particular pest, for example, parasitic wasps attack pest insects like caterpillars, beetles, aphids, etc. ETHOVISION allows researchers to automate the observation process in the exploratory phase. It measures aspects of the insects behaviour in the laboratory (e.g. walking and flight speed, turning rate, time distribution of different areas in space) that have a predictive value for its performance in the field.
A video tracking linked to a computerised image analysis system automatically records and classifies the spatial orientation and movement of an animal, taking away all-too-human frailties such as variation in classification caused by tiredness or different observers.

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...
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...
