Pimp my Spec: Upgrade for Magnetic Resonance Methods with a 1,000-fold Amplifier
University of Vienna

Researchers determine the structure and dynamics of proteins using NMR (Nuclear Magnetic Resonance) spectroscopy. Until now, however, much higher concentrations were necessary for in-vitro measurements of the biomolecules in solution than found in our body's cells. An NMR method enhanced by a very powerful amplifier, in combination with molecular dynamics simulation, now enables their detection and accurate characterization at physiological concentrations. This is reported by Dennis Kurzbach chemist at the University of Vienna and his colleagues in the journal "Science Advances". The team demonstrated their new method with the example of a protein that influences cell proliferation and thus also potential tumour growth.

Nano-sponges with potential for rapid wastewater treatment
University of Vienna

Efficient adsorbents for industrial wastewater treatment are important to minimize potential environmental damage. In particular, organic dyes, as a significant group of industrial pollutants, are usually highly water soluble, non-degradable and many are toxic to carcinogenic. Changxia Li and Freddy Kleitz from the Faculty of Chemistry of the University of Vienna together with colleagues now presented a new approach to design an innovative composite material, consisting of a nanoporous, ultrathin covalent organic framework (COF) anchored on graphene, that is highly efficient at filtering organic pollutants from water. The study was published in “Angewandte Chemie”.

Progress in Bioanalytics: Production of RNA Chips Significantly Simplified
University of Vienna

Biochips (microarrays) are modern analytical tools that allow thousands of individual detections to be performed simultaneously in a small amount of sample material. A team led by Mark Somoza from the Faculty of Chemistry at the University of Vienna has now presented a new method in "Nature Communications". With this method, commercially available DNA chips can be quickly and easily converted into RNA chips, which are otherwise much more difficult to produce. Such RNA microarrays help to elucidate the still unknown functions of RNA molecules in cells - an important prerequisite for advancing the diagnosis and treatment of diseases such as cancer.

Higher Voice Pitch Lets Female Faces Appear Younger
University of Vienna

Psychologists and biologists around Christina Krumpholz and Helmut Leder from the University of Vienna investigated whether voice pitch can influence how female faces are evaluated. Their conclusion: a higher voice does indeed influence how the corresponding face is evaluated. However, this does not apply to all ratings. Faces with a higher voice were rated as younger, but other assumptions that the faces are also rated as more attractive, more feminine or healthier do not apply. The study was published in the journal Frontiers in Psychology.

"Hot" Graphene Reveals Migration of Carbon Atoms
University of Vienna

The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot plate. The study by researchers at the Faculty of Physics of the University of Vienna was published in the journal Carbon.

Chemical Pollution Threatens Biodiversity
University of Vienna

Environmental chemical pollution threatens biodiversity. However, the complexity of this pollution remains insufficiently recognised by decision-makers - this is what international researchers led by Gabriel Sigmund from the University of Vienna and Ksenia Groh from the Swiss Federal Institute of Aquatic Science and Technology (Eawag) argue in the most recent issue of “Science”. Their letter appears shortly before the international negotiations on the “post-2020 Global Biodiversity Framework”. These will take place from 21st of June in Nairobi (Kenya).

Bolder marmoset monkeys learn faster than shy ones
University of Vienna

Individual traits seem to drive our learning success: for instance, conscientious individuals often show higher academic performance. A group of cognitive and behavioural biologists from University of Vienna conducted personality assessments and a battery of learning tests with common marmosets and found that such a link, intertwined with family group membership, exists in these monkeys, too. The study results were recently published in the journal “Scientific Reports”.

How our brain influences language change
University of Vienna

Our language is changing constantly. Researchers of the University of Vienna found that, over centuries, frequently occurring speech sound patterns get even more frequent. The reason for this development is that our brain can perceive, process and learn frequent, and thus prototypical sound patterns more easily than less frequent ones. The results of the study were published in the journal Cognitive Linguistics.

Artificial neurons go quantum with photonic circuits
University of Vienna

In recent years, artificial intelligence has become ubiquitous, with applications such as speech interpretation, image recognition, medical diagnosis, and many more. At the same time, quantum technology has been proven capable of computational power well beyond the reach of even the world’s largest supercomputer. Physicists at the University of Vienna have now demonstrated a new device, called quantum memristor, which may allow to combine these two worlds, thus unlocking unprecedented capabilities. The experiment, carried out in collaboration with the National Research Council (CNR) and the Politecnico di Milano in Italy, has been realized on an integrated quantum processor operating on single photons. The work is published in the current issue of the journal “Nature Photonics”.

Animal genomes: Chromosomes almost unchanged for over 600 million years
University of Vienna

By comparing chromosomes of different animal groups scientists at the University of Vienna led by Oleg Simakov and at the University of California made an astonishing discovery: Every animal species has almost the same chromosomal units that appear over and over again - and this has been the case since the first animals emerged about 600 million years ago. Using new principles, human chromosomes can now also be dissected into these primordial "elements". The new study has just been published in the journal Science Advances.

Learning to enjoy cognitive effort
University of Vienna

People like to take the path of least resistance when it comes to cognitive effort – a common assumption in cognitive psychology. Researchers at the University of Vienna and the Technische Universität Dresden have now come to a different conclusion: once people receive a reward for their effort investment, they later choose challenging tasks even if they no longer receive a reward. The study is currently published in the journal Proceedings of the National Academy of Science (PNAS).

Impossible material made possible inside a graphene sandwich
University of Vienna

Atoms bind together by sharing electrons. The way this happens depends on the atom types but also on conditions such as temperature and pressure. In two-dimensional (2D) materials, such as graphene, atoms join along a plane to form structures just one atom thick, which leads to fascinating properties determined by quantum mechanics. Researchers at the University of Vienna in collaboration with the Universities of Tübingen, Antwerp and CY Cergy Paris, together with Danubia NanoTech, have produced a new 2D material made of copper and iodine atoms sandwiched between two graphene sheets. The results were published in the journal Advanced Materials.
