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.

New Material Breaks World Record Turning Heat into Electricity
New Material Breaks World Record Turning Heat into Electricity
A new type of material generates electrical current very efficiently from temperature differences. This allows sensors and small processors to supply themselves with energy wirelessly. Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: If there is a temperature difference between the two ends of such a material, electrical voltage can be generated and current can start to flow.

Applying biodiversity conservation research in practice
Applying biodiversity conservation research in practice
One million species are threatened with extinction, many of them already in the coming decades. This unprecedented loss of biodiversity threatens valuable ecosystems and human well-being. But what is holding us back from putting conservation research into practice? The journal Biological Conservation has published a collection of 14 articles on this topic.

Ancient Rome: a 12,000-year history of genetic flux, migrations and diversity
Ancient Rome: a 12,000-year history of genetic flux, migrations and diversity
Scholars have been all over Rome for hundreds of years, but it still holds some secrets - for instance, relatively little is known about where the city's denizens actually came from. Now, an international team led by Researchers from the University of Vienna, Stanford University and Sapienza University of Rome, is filling in the gaps with a genetic history that shows just how much the Eternal City's populace mirrored its sometimes tumultuous history.

From cone snail venom to pain relief
From cone snail venom to pain relief
Conotoxins are bioactive peptides found in the venom that marine cone snails produce for prey capture and defense. They are used as pharmacological tools to study pain signalling and have the potential to become a new class of analgesics. To date, more than 10,000 conotoxin sequences have been discovered.

Atomic images reveal unusually many neighbors for some oxygen atoms
The identification of new chemical bonds is crucial for the design of new material structures. A team led by Jani Kotakoski at the University of Vienna and Jannik Meyer at the University of Tübingen has found unexpected new configurations of oxygen and nitrogen in graphene. Direct images of the actual atoms and the analysis of Life as we know it is based on just a handful of different types of atoms (called elements), among them carbon, nitrogen and oxygen.

Bioprinting: Living cells in a 3D printer
With a new process developed at TU Wien (Vienna), living cells can be integrated into fine structures created in a 3D printer - extremely fast and with very high resolution. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework.

Atomic force microscopy: new sensing element for high-speed imaging
Researchers at TU Wien have developed a new type of sensing element for atomic force microscopy, which enables a high measurement speed and can even image sensitive processes in living cells. High-definition images of minute objects are standard these days including the imaging of bacteria and viruses, and even molecules and individual atoms in extremely fine details.

Solving the Mystery of Quantum Light in Thin Layers
Solving the Mystery of Quantum Light in Thin Layers
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to glow in a highly unusual fashion.

Researchers show path of zearalenone through the womb using new technology The human foetus is considered to be particularly sensitive to environmental contaminants. A team led by Benedikt Warth from the Faculty of Chemistry at the University of Vienna and Tina Bürki from the Swiss Materials Science and Technology Institute, Empa, has now been able to demonstrate for the first time how the widespread food estrogen zearalenone behaves in the womb.

The fast dance of electron spins
Chemists investigate the interactions of metal complexes and light Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role.

Quantum Vacuum: Less than Zero Energy
Quantum Vacuum: Less than Zero Energy
Is it possible to borrow energy from an empty space? And if yes, do we have to give it back? Energy values smaller than zero are allowed - at least within certain limits. Energy is a quantity that must always be positive - at least that's what our intuition tells us. If every single particle is removed from a certain volume until there is nothing left that could possibly carry energy, then a limit has been reached.

A metronome for quantum particles
A new measurement protocol, developed at TU Wien (Vienna), makes it possible to measure the quantum phase of electrons - an important step for attosecond physics. It is like a microscope for time: Today's methods of attosecond physic allows us to measure extremely short time intervals. With the help of short laser pulses, physical processes can be investigated on a time scale of attoseconds - that is billionths of a billionth of a second.

From years to days: Artificial Intelligence speeds up photodynamics simulations
Scientists use deep neural networks to achieve simulations on long time scales The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna has now presented a method using artificial neural networks that drastically accelerates the simulation of light-induced processes.

Searching for the Origin of Life across the Universe
Researchers from European countries discuss life in the Universe at the University of Vienna Astrobiology is a young, rapidly developing branch of science that seeks to address the question of whether life exists, or has existed, elsewhere in the Universe. It is by nature an interdisciplinary science that explores the origins of life, the conditions, and processes that support or challenge life, the influence of different environmental conditions on preservation and detection of biosignatures of past and present life.

A new alphabet to write and read quantum messages with very fast particles
A new alphabet to write and read quantum messages with very fast particles
The interplay of quantum mechanics and special relativity requires a new alphabet to send reliable quantum messages Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to unambiguously decode the message and the communication fails.
