For years, the metal nanoparticles used in catalysts have been getting smaller and smaller. Now, a research team at TU Wien in Vienna, Austria have shown that everything is suddenly different when you arrive at the smallest possible size: a single atom.

How do you measure objects that you can't see under normal circumstances? Utrecht University and TU Wien (Vienna) open up new possibilities with special light waves. Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required - and this prerequisite is not always satisfied.
For years, the metal nanoparticles used in catalysts have been getting smaller and smaller. Now, a research team at TU Wien in Vienna, Austria have shown that everything is suddenly different when you arrive at the smallest possible size: a single atom. Metals such as gold or platinum are often used as catalysts.

In a new study, an international research team led by Sebastian Stumpf from the University of Vienna describes an exceptionally well-preserved skeleton of the ancient shark Asteracanthus. This extremely rare fossil find comes from the famous Solnhofen limestones in Bavaria, which was formed in a tropical-subtropical lagoon landscape during the Late Jurassic, about 150 million years ago.
With their expertise in microbiome research, the researchers at the Institute of Environmental Biotechnology were able to demonstrate how a specific bacterium inside the seeds of rice plants effectively and in an eco-friendly way inhibits destructive plant pathogens. Rice is the staple food of about half the world's population.
Why do metal oxide surfaces behave differently? At TU Wien, a new research method was found to answer important questions. Metal surfaces play a role as catalysts for many important applications - from fuel cells to the purification of car exhaust gases. However, their behaviour is decisively affected by oxygen atoms incorporated into the surface.
Changes in daylength are a well-established annual timing cue for animal behavior and physiology. An international collaboration of scientists led by Kristin Tessmar-Raible at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, now shows that, in addition to daylength, marine bristle worms sense seasonal intensity changes of UVA/deep violet light to adjust the levels of important neurohormones and their behavior.
Austrian Road Safety Board, and TU Graz have investigated tobogganing accidents for the first time in a computer-simulated crash test. The results: Wearing a helmet and the correct sitting position dramatically reduce the risk of injury for children while tobogganing. More than 2,200 people are injured in toboggan accidents in Austria every year.
Three papers unveil the extraordinary diversity of animal sex chromosomes The sex chromosomes genetically define the developmental fate of an embryo to become a male or a female individual, and usually appear as one pair of morphologically different chromosomes between sexes. For example, women have one pair of XX chromosomes, while men have one pair of XY chromosomes.
Most native species are going locally extinct, while introduced tropical species thrive An international team led by Paolo G. Albano from the Department of Palaeontology at the University of Vienna quantified a dramatic biodiversity collapse of up to 95 per cent of native species in the Eastern Mediterranean.
