Magnetic effect without a magnet
Magnetic effect without a magnet
Surprise in solid-state physics: The Hall effect, which normally requires magnetic fields, can also be generated in a completely different way - with extreme strength. Electric current is deflected by a magnetic field - in conducting materials this leads to the so-called Hall effect. This effect is often used to measure magnetic fields.

Two-phase material with surprising properties
Two-phase material with surprising properties
Microstructure and macroscopic electro-mechanical properties are closely coupled in so-called ferroelectric polymers. An explanation for the high temperature dependence of this coupling has now been found at TU Wien. In certain materials, electrical and mechanical effects are closely linked: for example, the material may change its shape when an electrical field is applied or, conversely, an electrical field may be created when the material is deformed.

Marmoset monkeys have personalities too
Marmoset monkeys have personalities too
In humans, differences in personalities have been evident since the ancient times. Personality in animals has long been ignored, but recently this question has received increasing research interest as it has been realized that personality has evolutionary and ecological significance. An international team of behavioral biologists from Austria, Brazil and the Netherlands, with Vedrana ¦lipogor from the University of Vienna as leading author of the study, designed a set of tasks to assess personality of common marmosets.

Origami with DNA
Origami with DNA
A team at TU Wien was able to answer important questions about the immune system - with a trick reminiscent of paper folding. T-cells are an important component of our immune system: with the receptors they carry on their surface, they can recognise highly specific antigens. Upon detection of an intruder, an immune response is triggered.

Optimal information about the invisible
Optimal information about the invisible
How do you measure objects that you can't see under normal circumstances? Utrecht University and TU Wien (Vienna) open up new possibilities with special light waves. Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required - and this prerequisite is not always satisfied.
