Surface physics: How water learns to dance
Surface physics: How water learns to dance
Pole dancing water molecules - Researchers at the TU Wien have seen this remarkable phenomenon on the surface of an important technological material. Perovskites are materials used in batteries, fuel cells, and electronic components, and occur in nature as minerals. Despite their important role in technology, little is known about the reactivity of their surfaces.

Enigmatic Comammox Microbes
Enigmatic Comammox Microbes
Nitrification plays a key role in Earth's natural nitrogen cycle and in agriculture. This process comprises two sequential steps, and for more than 100 years experts have assumed these steps to be carried out by different microorganisms. Now an international team of scientists led by Holger Daims and Michael Wagner, microbiologists at the University of Vienna, has discovered microbes that perform complete nitrification on their own: A result contrasting textbook knowledge and a milestone of microbiology.

Quantum Physics confirms "Spooky action at a distance"
A team of international researchers performed an experiment in the Vienna Hofburg to observe quantum entanglement with unprecedented certainty. Researchers in Anton Zeilinger's group from the Quantum Optics, Quantum Nanophysics and Quantum Information division of the University of Vienna physics department and from the Institute for Quantum Optics and Quantum Information (IQOQI) Vienna of the Austrian Academy of Sciences (OeAW), in an international collaboration, have demonstrated a definitive confirmation of quantum entanglement.

It's music to my eyes
It’s music to my eyes
When people are listening to music, their emotional reactions to the music are reflected in changes in their pupil size. Researchers from the University of Vienna and the University of Innsbruck, Austria, are the first to show that both the emotional content of the music and the listeners' personal involvement with music influence pupil dilation.

No more brown apples?
No more brown apples?
The longer an apple retains its beautiful colour, the better it is - especially for the food industry. Therefore, the industry works intensely on inhibiting the "browning" of fruits. Chemists of the University of Vienna around Annette Rompel moved a step closer to this ultimate goal. Everybody knows this phenomenon: After slicing an apple, it loses its appetising white colour very quickly, which does not only scare off children.

Early maternal loss has lifelong effects on chimpanzees
Early maternal loss has lifelong effects on chimpanzees
Wild-caught chimpanzees, who were orphaned and imported from Africa in their early infancy, exhibit an impaired social behaviour also as adults. So far long-term effects of early traumatic experiences on social behaviour were known only for humans and socially isolated chimpanzees. An Austrian-Dutch research team led by Elfriede Kalcher-Sommersguter and Jorg Massen published these results in the scientific journal "Scientific Reports".

Larger brains do not lead to high IQs
Is brain size related to cognitive ability of humans? This question has captured the attention of scientists for more than a century. An international team of researchers from the Universities of Vienna (Austria), Göttingen (Germany), and Tilburg (Netherlands) provides no evidence for a causal role of brain size for IQ test performance.

Ravens cooperate - but not with just anyone
Ravens cooperate - but not with just anyone
Ravens spontaneously solve a task that requires both coordination and cooperation - an ability that so far only a handful of species like chimpanzees and elephants have proved to master. A team of researchers led by Thomas Bugnyar of the Department of Cognitive Biology at the University of Vienna showed this for the ravens using an experimental set-up.

Reducing our own pain is also reducing empathy for pain in others
Reducing our own pain is also reducing empathy for pain in others
The ability to feel the pain of others is based on neurobiological processes which underlie pain experience in oneself. Using innovative methods, an international research team headed by psychologist Claus Lamm from the University of Vienna could show that a reduction of self-experienced pain leads to a reduction in empathy for pain in others as well.

Platinum and Iron Oxide Working Together Get the Job Done
Scientists at the Vienna University of Technology (TU Wien) have figured out how a platinum catalyst works. Its remarkable properties are not just due to the platinum, the iron-oxide substrate beneath also plays a role.

Even cockatoos conclude
Even cockatoos conclude
If there is a certain pool of choices (eg. A, B and C) and we can exclude A and B, we can easily deduce that C must be the appropriate choice. The ability of animals to be able to solve this sort of logical inference has been the focus of many studies in recent comparative cognitive research. However, only few managed to establish a comparatively applicable task.

Quantum diffraction at a breath of nothing
Quantum diffraction at a breath of nothing
Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a grating. In a European collaboration, researchers carried this idea to the extreme and observed the delocalization of molecules at the thinnest possible grating, a mask milled into a single layer of atoms.

Paving the way for a faster quantum computer
A team of physicists from the University of Vienna and the Austrian Academy of Sciences have demonstrated a new quantum computation scheme in which operations occur without a well-defined order. The researchers led by Philip Walther and Caslav Brukner used this effect to accomplish a task more efficiently than a standard quantum computer.

The quantum physics of artificial light harvesting
The quantum physics of artificial light harvesting
Plants and bacteria make use of sunlight with remarkably high efficiency: nine out of ten absorbed light particles are being put to use in an ordinary bacterium. For years, it has been a pressing question of modern research whether or not effects from quantum physics are responsible for this outstanding performance of natural light harvesters.

Good Quantum States and Bad Quantum States
Good Quantum States and Bad Quantum States
[ Florian Aigner A theoretical trick allows scientists to describe quantum states of thousands of atoms. If standard methods were used, all storage capacity in the world would not be enough to do this. For a long time, quantum experiments were only carried out with a small number of particles. Even the behaviour of single atoms or molecules can be very hard to describe.

Surprise from the Deep Ocean
Archaea belong together with Bacteria to the first organisms that emerged on Earth. These microorganisms existed hundreds of millions of years before the more complex cell structures of Eukaryotes developed that gave rise to macroscopic life, i.e. plants and animals. An international team of researchers from Uppsala (Sweden), Bergen (Norway) and Vienna (Austria), has found a novel group of Archaea in deep ocean sediments, who are the closest direct relatives of the eukaryotic lineage.

Large heads, narrow pelvises and difficult childbirth in humans
In humans, the size of the neonatal skull is large relative to the dimensions of the birth canal in the female pelvis. This "obstetric dilemma" is the reason why childbirth is slower and more difficult in humans than in most other primates. Barbara Fischer and Philipp Mitteroecker from the Centre of Ecological and Evolutionary Synthesis, University of Oslo, and the Department of Theoretical Biology, University Vienna, identified adaptations in the morphology of the human body, which were unknown so far, and which contribute to ameliorate this obstetric dilemma.
