Atoms, molecules or even living cells can be manipulated with light beams. At TU Wien a method was developed to revolutionize such "optical tweezers". They are reminiscent of the "tractor beam" in Star Trek: special light beams can be used to manipulate molecules or small biological particles. Even viruses or cells can be captured or moved.

Machine learning speeds up atomistic simulations of water and ice
Machine learning speeds up atomistic simulations of water and ice
Why is water densest at around 4 degrees Celsius' Why does ice float? Why does heavy water have a different melting point compared to normal water? Why do snowflakes have a six-fold symmetry? A collaborative study of researchers from the École Polytechnique Fédérale de Lausanne, the University of Göttingen and the University of Vienna and just published in the Proceedings of the National Academy of Sciences of the USA, provides physical insights into these questions by marrying data-driven machine learning techniques and quantum mechanics.

Marmoset monkeys expect the melody's closing tone
Marmoset monkeys expect the melody’s closing tone
In speech and music, words and notes depend on each other. Humans are highly sensitive to such dependencies, but the evolutionary origins of this capacity are poorly understood. Cognitive biologists at the University of Vienna conducted playback experiments with common marmoset monkeys and found that sensitivity to dependencies might have been present in the shared ancestor of marmosets and humans.

Quantum Tricks to Unveil the Secrets of Topological Materials
Quantum Tricks to Unveil the Secrets of Topological Materials
[ Florian Aigner "Topological materials" are very interesting for technology, but difficult to study. TU Wien (Vienna) and the University of Science and Technology in China are presenting new approaches. Electrons are not just little spheres, bouncing through a material like a rubber ball. The laws of quantum physics tell us that electrons behave like waves.

Artificial intelligence for better computer graphics
Artificial intelligence for better computer graphics
[ Florian Aigner At the TU Wien (Vienna), neural networks have been developed which make it much easier to create photorealistic pictures of a wide variety of materials. If computer-generated images are to look realistic, different materials have to be presented differently: The metallic sheen of a coin looks quite different from the dull gloss of a wooden plate or the slightly transparent skin of a grape.

First diode for magnetic fields
First diode for magnetic fields
Innsbruck quantum physicists have constructed a diode for magnetic fields and then tested it in the laboratory. The device, developed by the research groups led by the theorist Oriol Romero-Isart and the experimental physicist Gerhard Kirchmair, could open up a number of new applications. Electric diodes are essential electronic components that conduct electricity in one direction but prevent conduction in the opposite one.

Transparent Fruit Flies
Transparent Fruit Flies
Advances in cellular microscopy: at TU Wien (Vienna), flies were made transparent, so that individual nerve cells, marked with fluorescent molecules, can be examined directly in the animal. The nervous system of an animal can be studied by cutting it up into thin layers - however this inevitably leads to the destruction of the cellular structures in the tissue.

A Chip with Blood Vessels
A Chip with Blood Vessels
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way. Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more difficult task.

Re-inventing the hook
Re-inventing the hook
Orangutans spontaneously bend straight wires into hooks to fish for food The bending of a hook into wire to fish for the handle of a basket is surprisingly challenging for young children under eight years of age. Now cognitive biologists and comparative psychologists from the University of Vienna, the University of St Andrews and the University of Veterinary Medicine Vienna around Isabelle Laumer and Alice Auersperg studied hook tool making for the first time in a non-human primate species - the orangutan.

Quantum systems: Same, but different
Quantum systems: Same, but different
When quantum particles swirl about, they still obey universal laws. Different quantum systems can show the same behaviour - this has been demonstrated by two different experiments at TU Wien and Heidelberg University. Some things are so complicated that it is completely impossible to precisely calculate them.

RNA Microchips
RNA Microchips
Ribonucleic acid (RNA) is, along with DNA and protein, one of the three primary biological macromolecules and was probably the first to arise in early life forms. In the "RNA world" hypothesis, RNA is able to support life on its own because it can both store information and catalyze biochemical reactions.

The car is becoming communicative thanks to antennas in the roof
Telecommunications is becoming ever more important for vehicles. At TU Wien, a new antenna concept has now been developed for cars. Driving without communication technology has now become almost unthinkable. It seems quite normal to us that navigation systems regularly update their maps and shows us the way using satellite data, or that we can make phone calls while driving.

Bioethanol in diesel engines: a contribution to sustainability
Bioethanol in diesel engines: a contribution to sustainability
Ethanol can make an important contribution to climate protection: at TU Wien, a diesel engine has been developed that can run on over 70% bioethanol. TU Wien has developed an engine that uses two different types of fuel simultaneously: it uses both bioethanol and diesel, which is used for ignition. A special duel-fuel combustion process has been developed for this purpose, which now enables the use of a large proportion of bioethanol in diesel engines.

String Theory: Is Dark Energy even Allowed?
String Theory: Is Dark Energy even Allowed?
A new conjecture causes excitement in the string theory community. Timm Wrase of the Vienna University of Technology has now published much-discussed results on recent new developments. In string theory, a paradigm shift could be imminent. In June, a team of string theorists from Harvard and Caltech published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible with our current understanding of "dark energy" - but only with "dark energy" can we explain the accelerated expansion of our current universe.
