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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
