Getting hook bending off the hook
Getting hook bending off the hook
The bending of a hook into wire to fish for the handle of a basket by the crow Betty 15 years ago stunned the scientific world. However, the finding was recently relegated as similar behavioural routines were discovered in the natural repertoire of the same species, suggesting the possibility that Betty's tool manufacture was less intelligent than previously believed.

Electrical current provides a look inside the lungs
A new imaging technique, Electrical Impedance Tomography (EIT), will soon be used to monitor important bodily functions. A collaborative project between TU Wien, the Medical University of Vienna and the University of Veterinary Medicine Vienna, has enabled significant progress to be made with this technology.

New ERC grant - using mercury to explain the universe
New ERC grant - using mercury to explain the universe
Simon Stellmer has been awarded a prestigious ERC Starting Grant. He will now use ultracold mercury atoms to investigate fundamental symmetries in nature. Why is there matter in the universe at all? To date there has been no conclusive answer to this question. Our understanding of the Big Bang is based on the assumption that equal amounts of antimatter and matter were created.

Quantum Ruler for Biomolecules
Quantum Ruler for Biomolecules
Quantum physics teaches us that unobserved particles may propagate through space like waves. This is philosophically intriguing and of technological relevance: a research team at the University of Vienna has demonstrated that combining experimental quantum interferometry with quantum chemistry allows deriving information about optical and electronic properties of biomolecules, here exemplified with a set of vitamins.

When fish swim in the holodeck
When fish swim in the holodeck
Behavior experiments are useful tools to study brain function. Standard experiments to investigate behavior in popular lab animals such as fish, flies or mice however only incompletely mimic natural conditions. The understanding of behavior and brain function is thus limited. Virtual Reality (VR) helps in generating a more natural experimental environment but requires immobilization of the animal, disrupting sensorimotor experience and causing altered neuronal and behavioral responses.

Bacteria stab amoebae with micro-daggers
Bacteria stab amoebae with micro-daggers
Researchers from ETH Zurich and the University of Vienna have discovered a type of bacteria that uses tiny daggers to prevent itself from being eaten by amoebae. The scientists also resolved the three-dimensional structure of the mechanism that allows the micro-daggers to be shot quickly. Bacteria have to watch out for amoeba.

Massive particles test standard quantum theory
Massive particles test standard quantum theory
In quantum mechanics particles can behave as waves and take many paths through an experiment, even when a classical marble could only take one of them at any time. However, it requires only combinations of pairs of paths, rather than three or more, to determine the probability for a particle to arrive somewhere.

What flowers looked like 100 million years ago
What flowers looked like 100 million years ago
Flowering plants with at least 300,000 species are by far the most diverse group of plants on Earth. They include almost all the species used by people for food, medicine, and many other purposes. However, flowering plants arose only about 140 million years ago, quite late in the evolution of plants, toward the end of the age of the dinosaurs, but since then have diversified spectacularly.

It's never too cold for quantum
It’s never too cold for quantum
The peculiar characteristics demonstrated by 'quantum critical points' at absolute zero remain one of the great unsolved mysteries of science. Normally, there needs to be a change in temperature in order to see a phase transition: a liquid gets cold, it freezes; a metal heats up, it loses its magnetic properties.

Magnetic Quantum Objects in a
Magnetic Quantum Objects in a "Nano Egg-Box"
Magnetic quantum objects in superconductors, so-called "fluxons", are particularly suitable for the storage and processing of data bits. Computer circuits based on fluxons could be operated with significantly higher speed and, at the same time, produce much less heat dissipation. Physicists around Wolfgang Lang at the University of Vienna and their colleagues at the Johannes-Kepler-University Linz have now succeeded in producing a "quantum egg-box" with a novel and simple method.

Marine microplastics: many past studies contaminated
Marine microplastics: many past studies contaminated
Wherever you look, you are almost guaranteed to find tiny plastic particles. However, a study conducted by TU Wien has revealed that, in many cases, what is thought to be plastic found in samples of seawater may actually be natural fibres from lab coats. Plastic is constantly finding its way into the ocean - it comes from ships, unsecured landfill sites and the sewage system.

Nickel is Crucial for the Earth's Magnetic Field
Nickel is Crucial for the Earth’s Magnetic Field
Scientists at TU Wien and Würzburg University are changing our idea of the earth's magnetic field: iron alone cannot explain the concept of the geodynamo. The crucial ingredient is nickel. It only takes a simple compass to demonstrate that the earth has a magnetic field - but it is quite difficult to explain how exactly it is created.

CO2-neutral hydrogen from biomass
CO2-neutral hydrogen from biomass
Without fossil fuels, there can be no blast furnace process - but hydrogen could play a more important role in the future. An environmentally friendly process is being developed at TU Wien by which biomass can be used to produce a hydrogen-rich gas that can then be employed in various ways in the iron and steel industry.

Bridges in Austria often exceed expectations
Bridges in Austria often exceed expectations
Assessing old bridges using modern standards is no mean feat. Studies conducted by TU Wien show that many bridges are actually significantly more stable than might be expected, often rendering costly restoration work unnecessary. Deciding which bridges need to be restored in the near future and which are still in good condition can have extremely expensive repercussions.

Graphene encapsulation provides unprecedented view of the diffusion and rotation of fullerene molecules
Graphene encapsulation provides unprecedented view of the diffusion and rotation of fullerene molecules
Scientists at the University of Vienna have created a new hybrid structure, termed buckyball sandwich, by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine for the first time soccerball-like fullerenes, each consisting of sixty carbon atoms, and graphene, a one-atom thick layer of carbon.

Measured for the first time: direction of light waves changed by quantum effect
The 'quantized magneto-electric effect' has been demonstrated for the first time in topological insulators at TU Wien, which is set to open up new and highly accurate methods of measurement. A light wave sent through empty space always oscillates in the same direction. However, certain materials can be used to rotate the direction in which the light is oscillating when placed in a magnetic field.

Testing Quantum Field Theory in a Quantum Simulator
A new way to characterize many-particle quantum systems has been presented in the journal "Nature" by TU Wien (Vienna) and Heidelberg University. Quantum simulators can now be used to take a deeper look at previously unanswered questions. What happened right after the beginning of the universe? How can we understand the structure of quantum materials' How does the Higgs-Mechanism work? Such fundamental questions can only be answered using quantum field theories.

In both love and war, alligators signal size by bellowing
In both love and war, alligators signal size by bellowing
American alligators produce loud, low-frequency vocalizations called "bellows". Cognitive biologists at the University of Vienna, Stephan Reber and Tecumseh Fitch, investigated these vocalizations and found that they reveal the caller's body size. Alligators can use this information to avoid unpromising contests for mates and breeding areas.
