The fast dance of electron spins
Chemists investigate the interactions of metal complexes and light Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, plays an important role.

Searching for the Origin of Life across the Universe
Researchers from European countries discuss life in the Universe at the University of Vienna Astrobiology is a young, rapidly developing branch of science that seeks to address the question of whether life exists, or has existed, elsewhere in the Universe. It is by nature an interdisciplinary science that explores the origins of life, the conditions, and processes that support or challenge life, the influence of different environmental conditions on preservation and detection of biosignatures of past and present life.

A new alphabet to write and read quantum messages with very fast particles
A new alphabet to write and read quantum messages with very fast particles
The interplay of quantum mechanics and special relativity requires a new alphabet to send reliable quantum messages Quantum information relies on the possibility of writing messages in a quantum particle and reading them out in a reliable way. If, however, the particle is relativistic, meaning that it moves with velocities close to the speed of light, it is impossible for standard techniques to unambiguously decode the message and the communication fails.

A molecular "Trojan Horse"
The research group of Nuno Maulide from the Faculty of Chemistry of the University of Vienna has, in cooperation with the Research Center for Molecular Medicine (CeMM) of the Austrian Academy of Sciences, achieved the synthesis of a potential immunosuppressive agent by modification of a naturally occurring compound.

Quantum gravity's tangled time
Quantum gravity’s tangled time
The theories of quantum mechanics and gravity are notorious for being incompatible, despite the efforts of scores of physicists over the past fifty years. However, recently an international team of researchers led by physicists from the University of Vienna, the Austrian Academy of Sciences as well as the University of Queensland (AUS) and the Stevens Institute of Technology (USA) have combined the key elements of the two theories describing the flow of time and discovered that temporal order between events can exhibit genuine quantum features.

Sleeping unsafely tucked in to conserve energy in nocturnal migratory songbirds
Sleeping with the head tucked in the back feathers is a common behavior exhibited by most species of birds. In a recent study, scientist from the Vetmeduni Vienna and the University of Vienna found, that the hiding of the head during sleep reduces heat loss and conserves energy reserves. However sleeping with the head tucked is risky for the birds.

"Qutrit": Complex quantum teleportation achieved for the first time
Austrian and Chinese scientists have succeeded in teleporting three-dimensional quantum states for the first time. High-dimensional teleportation could play an important role in future quantum computers. Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility.

How do atoms vibrate in graphene nanostructures?
Innovative new electron spectroscopy technique pushes the limits of Nanospectroscopy for materials design In order to understand advanced materials like graphene nanostructures and optimize them for devices in nano-, optoand quantum-technology it is crucial to understand how phonons - the vibration of atoms in solids - influence the materials' properties.

Symphony of genes
Symphony of genes
One of the most exciting discoveries in genome research was that the last common ancestor of all multicellular animals - which lived about 600 million years ago - already possessed an extremely complex genome. Many of the ancestral genes can still be found in modern day species (e.g., human). However, it has long been unclear whether the arrangement of these genes in the genome also had a certain function.

How to trick electrons to see the hidden face of crystals
How to trick electrons to see the hidden face of crystals
Researchers try a trick for complete 3D analysis of submicron crystals The 3D analysis of crystal structures requires a full 3D view of the crystals. Crystals as small as powder, with edges less than one micrometer, can only be analysed with electron radiation. With electron crystallography, a full 360-degree view of a single crystal is technically impossible.

When the pigeon and the letter do not travel together
When the pigeon and the letter do not travel together
In standard communication the pigeon always carries the message; the information is linked to a physical entity/particle. Counter to intuition, in a new counterfactual communication protocol published in NPJ Quantum Information, scientists from the University of Vienna, the University of Cambridge and the MIT have experimentally demonstrated that in quantum mechanics this is not always true, thereby contradicting a crucial premise of communication theory.

Mitosis is the process by which the genetic information encoded on chromosomes is equally distributed to two daughter cells, a fundamental feature of all life on earth. Scientists led by Alexander Dammermann at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, now examine how centrioles contribute to this process.

A connection between quantum correlations and spacetime geometry
Researchers of the Academy explore the consequences of locality for measurements distributed in spacetime. Their article has now been published in the Nature journal "Quantum Information". Locality is a fundamental principle behind all physical interactions. It says that each physical system can only interact with other systems in its immediate vicinity, so that interactions between two distant objects must be mediated by an intermediary.
