Human environmental genome recovered in the absence of skeletal remains

Innovative approach permits the identification of DNA in samples of environmental material

14-Jul-2021

Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which difficults the analyses to be performed with these sequences. A study led by Ron Pinhasi and Pere Gelabert of ...

Crystalline supermirrors for trace gas detection in environmental science and medicine

Analysis of particularly complex gas mixtures with unprecedented accuracy

25-May-2021

In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating ...

Environmental exposures affect therapeutic drugs

High-resolution mass spectrometry promotes new methods for analysis

16-Dec-2020

Humans are exposed to various environmental or dietary molecules that can attenuate or even increase the effect of therapeutic drugs. Studies on the industrial chemical bisphenol A and the phytoestrogen genistein, for example, have shown drug-exposome interactions. However, interactions between ...

Evolution in real-time: How bacteria adapt to their hosts

Some bacteria become increasingly infectious when they have to move from cell to cell in order to survive

20-Aug-2020

Bacteria that invade animal cells in order to multiply are widespread in nature. Some of these are pathogens of humans and animals. In the environment, they are often found inside unicellular organisms. A research team led by Matthias Horn at the Centre for Microbiology and Environmental Systems ...

New simulation-experiment combination allows deeper insights into ultrafast light-induced processes

14-Feb-2020

Researchers from Graz University of Technology and the University of Vienna are demonstrating for the first time how the energy flow between strongly interacting molecular states can be better described. Since the 1990s, femtochemistry has been researching ultrafast processes at the molecular ...

How do atoms vibrate in graphene nanostructures?

Innovative new electron spectroscopy technique pushes the limits of Nanospectroscopy for materials design

14-Aug-2019

In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, opto- and quantum-technology it is crucial to understand how phonons – the vibration of atoms in solids – influence the materials’ properties. Researchers from the University of Vienna, ...

How to separate nanoparticles by “shape”

New strategy to separate molecules

13-Jun-2019

In our daily lives, the purpose and function of an item is defined by either its material, e.g. a rain jacket is fabricated of water-proof material, or its shape, e.g. a wheel is round to enable a rolling motion. What is the impact of the two factors on the nanoscale? The impact of material, ...

Artificial intelligence for obtaining chemical fingerprints

Neural networks carry out chemical simulations in record time

28-Sep-2017

Researchers at the Universities of Vienna and Göttingen have succeeded in developing a method for predicting molecular infrared spectra based on artificial intelligence. These chemical "fingerprints" could only be simulated by common prediction techniques for small molecules in high quality. With ...

Quantum diffraction at a breath of nothing

Physicists build stable diffraction structure in atomically thin graphene

27-Aug-2015

Quantum physics tell us that even massive particles can behave like waves, as if they could be in several places at once. This phenomenon is typically proven in the diffraction of a matter wave at a grating. In a European collaboration, researchers carried this idea to the extreme and observed ...

Quantum physics enables revolutionary imaging method

29-Aug-2014

Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), the Vienna Center for Quantum Science and Technology (VCQ), and the University of Vienna have developed a fundamentally new quantum imaging technique with strikingly counterintuitive features. For the first time, ...
