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.

Researchers create new technique for manipulating polarization of terahertz radiation

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
