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...

Experiments on the quantum wave nature have enabled researchers to precisely measure tiny forces and displacements as well as to shed light onto the unexplored zone between the microscopic realm of quantum physics and our everyday world Matter wave interferometry has a long standing tradition at the University of Vienna, where the first quantum interference of large molecules has already been observed in 1999. Nowadays scientists are hunting down evidence for the quantum mechanical...

New Method Developed For The Construction Of Building Blocks At The Nanoscale
2013-01-17 11:25:42

University of Vienna Barbara Capone of the Computational Physics Group of the University of Vienna has developed a new method for the construction of building blocks at the nanoscale. The researcher in Soft Matter Physics, who works at the group of Christos Likos, Professor for Multiscale Computational Physics, is specialized on topics of self-assembly of materials at the nanoscale and she has published, together with her colleagues, a paper at the prestigious Journal "Physical Review...

Quantum Object Behavior Depends On Measurement Apparatus Used
2013-01-09 14:54:07

University of Vienna Whether a quantum object behaves like a wave or like a particle depends (according to the Copenhagen interpretation) on the choice of measurement apparatus used for observing the system, and therefore on the type of measurement performed. Anton Zeilinger's team of physicists at the University of Vienna and the Austrian Academy of Sciences has recently taken this phenomenon further than ever. Whether a certain photon behaves like a particle or like a wave depends on...

Using Uranium-236 From The 1960s To Investigate Ocean Currents
2012-12-17 12:22:49

University of Vienna In the period of atmospheric nuclear testing in the 1950s and 1960s significant amounts of uranium-236 were distributed world-wide. Despite this, uranium-236 has mostly eluded detection and clear attribution to this source. A team of three researchers based in Austria and Australia lead by Stephan Winkler have identified the bomb-pulse of this isotope in corals from the Caribbean Sea. Uranium is readily dissolved in seawater, and therefore is carried by ocean currents....

"In our current paper we present new computational results that explore how membranes may influence crucial biological processes", explains Richard Matthews, Lise-Meitner-Fellow at the University of Vienna and first author of the study. The focus of the investigation is the self-assembly of microscopic particles, the formation of structures or patterns without human intervention. More specifically, the effect of the interactions between membranes and proteins, which can influence the...

How Does The Swim Bladder Affect Hearing In Cichlid Fish?
2012-08-08 11:35:57

"Sound vibrations are transmitted to the inner ear via anterior extensions of the swim bladder or via bony ossicles", the biologist Tanja Schulz-Mirbach explains how swim bladders may serve for hearing. The hearing sensitivity improves considerably in this way. The anterior part of the swim bladder functions in specialized fish species similar to an ear drum. Up to now the effects of the different swim bladder morphologies have not been investigated in detail in cichlid fishes. The...

A modeling study from the European Alps suggests that population declines to be observed during the upcoming decades will probably underestimate the long-term effects of recent climate warming on mountain plants. A European team of ecologists around Stefan Dullinger from the Department of Conservation Biology, Vegetation and Landscape Ecology of the University of Vienna presents a new modeling tool to predict migration of mountain plants which explicitly takes population dynamic processes...

Quantum Physics Mimics Spooky Action Into The Past
2012-04-23 09:37:30

Physicists of the group of Prof. Anton Zeilinger at the Institute for Quantum Optics and Quantum Information (IQOQI), the University of Vienna, and the Vienna Center for Quantum Science and Technology (VCQ) have, for the first time, demonstrated in an experiment that the decision whether two particles were in an entangled or in a separable quantum state can be made even after these particles have been measured and may no longer exist. Their results will be published this week in the journal...

A pan-European study published in Science shows that mountain plants across the continent are moving to higher altitudes. This often results in raised species numbers on mountain tops, when colonizers from lower down start to dwell on the summits. This study, however, also shows that upward shifts can lead to a reduction in species richness. The paper is based on detailed surveys of 66 mountain summits distributed between the north of Europe and the southern Mediterranean Sea. An...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
