New Model For Evolution Of Paired Appendages
2014-01-27 11:28:06

University of Vienna This news release is available in German. All of us backboned animals – at least the ones who also have jaws – have four fins or limbs, one pair in front and one pair behind. These have been modified dramatically in the course of evolution, into a marvelous variety of fins, legs, arms, flippers, and wings. But how did our earliest ancestors settle into such a consistent arrangement of two pairs of appendages? – Because we have a belly. Researchers in the...

Development Of Cryptic Worms Provides New Insights Into Molluscan Evolution
2013-10-18 12:20:59

University of Vienna There are still a lot of unanswered questions about mollusks, e.g. snails, slugs and mussels. The research group of Andreas Wanninger, Head of the Department of Integrative Zoology of the University of Vienna, took a detailed look at the development of cryptic worms. The larvae of the "wirenia argentea" hold a much more complex muscular architecture than their adults -- they remodel during their metamorphosis. That's a clue that the ancestors had a highly complex...

Cockatoos Know What Goes On Behind Barriers
2013-07-29 09:58:11

University of Vienna How do you know that the cookies are still there although they have been placed out of your sight into the drawer? How do you know when and where a car that has driven into a tunnel will reappear? The ability to represent and to track the trajectory of objects, which are temporally out of sight, is highly important in many aspects but is also cognitively demanding. Alice Auersperg and her team from the University of Vienna and Oxford show that "object permanence"...

Researchers Demonstrate Leap Forward In Optical Coating Technology
2013-07-23 10:07:55

University of Vienna Although it may not be immediately obvious, the mechanical properties of optical components have a significant impact on the performance of lasers employed in precision sensing applications. Currently, the mechanical damping of such components, and the inherent mechanical fluctuations they generate, present a roadblock to further advancement of ever more precise measurements of time and space. For the past decade, researchers in the precision measurement community have...

The unique properties of graphene such as its incredible strength and, at the same time, its little weight have raised high expectations in modern material science. Graphene, a two-dimensional crystal of carbon atoms packed in a honeycomb structure, has been in the focus of intensive research which led to a Nobel Prize of Physics in 2010. One major challenge is to successfully integrate graphene into the established metal-silicide technology. Scientists from the University of Vienna and their...

The Science Behind A Self-assembled Nano-carbon Helix
2013-05-16 12:42:51

University of Vienna Nanotechnology draws on the fabrication of nanostructures. Scientists have now succeeded in growing a unique carbon structure at the nanoscale that resembles a tiny twirled moustache. Their method might lead the way to the formation of more complex nano-networks. Researchers of the Electronic Properties of Materials Group at the Faculty of Physics (University of Vienna) and their international collaborators have published their results in the new open access journal of...

Brighter Future From Photonic Quantum Computers
2013-05-13 12:40:14

University of Vienna Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the Faculty of Physics, University of Vienna succeeded in prototyping a new and highly resource efficient model of a quantum computer — the boson sampling computer. The results will be published in the upcoming issue of the renowned scientific journal "Nature...

20 to 40% of European plant and animal species endangered A new study on extinction risk based on extensive data from 7 taxonomic groups and 22 European countries has shown that proportions of plant and animal species being classified as threatened on national Red Lists are more closely related to socio-economic pressure levels from the beginning than from the end of the 20th century. Stefan Dullinger of the University of Vienna and Franz Essl from the Austrian Environment Agency together...

No More Loopholes For Photons
2013-04-15 14:53:36

University of Vienna A team led by the Austrian physicist Anton Zeilinger has now carried out an experiment with photons, in which they have closed an important loophole. The researchers have thus provided the most complete experimental proof that the quantum world is in conflict with our everyday experience. The results of this study appear this week in the renowned journal Nature (Advance Online Publication/AOP). When we observe an object, we make a number of intuitive assumptions,...

Nano-machines Developed Create 'Bionic Proteins'
2013-02-15 15:38:30

University of Vienna [ Watch The Video Animation Of Folding Pathway ] Physicists of the University of Vienna together with researchers from the University of Natural Resources and Life Sciences Vienna developed nano-machines which recreate principal activities of proteins. They present the first versatile and modular example of a fully artificial protein-mimetic model system, thanks to the Vienna Scientific Cluster (VSC), a high performance computing infrastructure. These "bionic...
