New Horizons for Arterial Spin Labeling
By Stefan M. Spann Over the last two decades researchers have been working on a contrast-agent free magnetic resonance imaging (MRI) method called Arterial Spin Labeling (ASL) for detecting blood flow changes within the brain and other organs. Recent improvements in imaging hardware, new strategies for efficient data sampling and sophisticated reconstruction algorithms have now brought the application out of research into clinical practice.

A Remote Control for Everything Small
A Remote Control for Everything Small
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.

ZombieLoad 2.0 also attacks new processors and software patch
ZombieLoad 2.0 also attacks new processors and software patch
By Birgit Baustädter At the beginning of 2019, an international research team led by Daniel Gruss, Michael Schwarz and Moritz Lipp from TU Graz discovered the processor loophole ZombieLoad. Since then there has been a software patch and new processors. But with a new variant of the old attack these are no longer safe either.

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.

Graz universities celebrated their flashes of genius
Graz universities celebrated their flashes of genius
By Christoph Pelzl Med Uni Graz, TU Graz and Uni Graz yesterday honoured those scientists who have pioneered research in the last two years with their inventions and patents. Since 2015, the Medical University of Graz, Graz University of Technology and the University of Graz have been honouring particularly "inventive" researchers in a joint ceremony every two years.

From Lego to New Material Building Blocks
From Lego to New Material Building Blocks
By Birgit Baustädter Materials researcher Florian Lackner "wraps" highly reactive alkali metal atoms in gold and examines them in his laser laboratory. A job he dreamed of when he was a child. "What I'm doing now is exactly what I've always wanted to do." Florian Lackner has achieved what many wish for.

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.

Minimizing post-harvest food losses
Minimizing post-harvest food losses
By Barbara Gigler Research team from Graz develops biological methods to improve the shelf life of fruit and vegetables. Additional at the end of the text The crops have been harvested. Now it is important to store the various crops well and to preserve them as long and as carefully as possible. Post-harvest losses due to spoilage, however, represent a significant problem along the supply chain and lead to profit losses in the millions.

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
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.

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.
