Amber Provides New Insights Into the Earth's Atmosphere
Amber Provides New Insights Into the Earth’s Atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant resins. The results suggest that atmospheric oxygen was considerably lower in the Earth's geological past than previously assumed.

Chronobiology: Not everything revolves around the sun
Researchers in Vienna shed light on the interplay of a worm's inner clocks For a long time, molecular chronobiology has almost exclusively focused on circadian rhythms that are driven by the changes of day and night and hence follow the daily cycle of the sun. However, especially in the sea, the cradle of evolution, organisms set their pace also according to the moon.

A completely new atomic crystal dynamic of the white pigment titanium dioxide discovered
An international team of researchers at Vienna University of Technology in Austria and at Princeton University in the USA has confirmed theoretically-predicted interactions between single oxygen molecules and crystalline titanium dioxide. The results, which could be of importance for a variety of applications, have been published in the current.

Detection of single photons via quantum entanglement
Detection of single photons via quantum entanglement
A team of quantum physicists in Innsbruck led by Christian Roos and Cornelius Hempel have realised an extremely sensitive method for the spectroscopy of atomic and molecular atoms. This technique can be used to closely study a number of particles. The scientists have published their findings Photonics.

Improving Measurements by Reducing Quantum Noise
Researchers from Vienna University of Technology have built a new interferometer for trapped, ultracold atomic gases. By strongly suppressing the quantum noise, which ultimately limits the performance of interferometers, they were able to curb the effect of atomic interactions, and increase the interrogation time of their interferometer.

Data Highways for Quantum Information
Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables. Now, they have shown that their technique enables storage of quantum information over a sufficiently long period of time to realize global quantum networks based on optical fibers. Researchers at the Vienna University of Technology quantum mechanically couple atoms to glass fiber cables.

The Dance of the Atoms
Catalysts can stop working when atoms on the surface start moving. At the Vienna University of Technology, this dance of the atoms could now be observed and explained. Lone people standing in a ballroom don't tend to move a lot. It's only when they find a suitable dance partner that rapid motion sets in.

Helicopter-light-beams - a new tool for quantum optics
A light wave oscillates perpendicular to its propagation direction - that is what students learn in school. However, scientists of the Vienna University of Technology (TU Vienna) now perform atom-physics experiments with light oscillating in the longitudinal direction. Storing light in a bottle is easier than one might think: Laser light can be coupled into an optical glass fiber in such a way that it does not travel along the fiber but rather spirals around it in a bulged, bottle-like section.

Cross-talk between signaling cascades
Cross-talk between signaling cascades
Signaling cascades communicate and integrate extracellular signaling cues spatially and temporally via formation of defined protein-protein interactions. Scientists from the Institute of Biochemistry in Innsbruck discovered a unique mechanism which is based on binary protein-protein interactions and which explains cross talk between critically regulated signaling cascades.

New Material Promises Better Solar Cells
Researchers at the Vienna University of Technology show that a recently discovered class of materials can be used to create a new kind of solar cell. Single atomic layers are combined to create novel materials with completely new properties. Layered oxide heterostructures are a new class of materials, which has attracted a great deal of attention among materials scientists in the last few years.
