Scientists use deep neural networks to achieve simulations on long time scales The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna has now presented a method using artificial neural networks that drastically accelerates the simulation of light-induced processes.
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.
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.
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.
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.
Scientists study individuals who lived during the Migration Period Led by Ron Pinhasi from the University of Vienna, Austria and Mario Novak from the Institute for Anthropological Research in Zagreb, Croatia the study combines bioarchaeological isotopic and ancient DNA methods to analyze the dietary patterns, sex, and genetic affinities of three Migration Period (5th century CE) individuals who were recovered from a pit in the city of Osijek in eastern Croatia.
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.
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.
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.
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.
Ultradense arrays of magnetic quanta in high-temperature superconductors The properties of high-temperature superconductors can be tailored by the introduction of artificial defects. An international research team around physicist Wolfgang Lang at the University of Vienna has succeeded in producing the world's densest complex nano arrays for anchoring flux quanta, the fluxons.
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.
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.
Metallophilic microorganisms could benefit from the heavy metal in harsh survival conditions A boiling point of 5900 degrees Celsius and diamond-like hardness in combination with carbon: tungsten is the heaviest metal, yet has biological functions - especially in heat-loving microorganisms. A team led by Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna report for the first time rare microbial-tungsten interactions at the nanometer range.
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.
The unique tooth structure of the great white shark gives new insights into its origin Mackerel sharks (Lamniformes) are a group consisting of some of the most iconic sharks we know, including the mako shark (the fastest shark in the world), the infamous great white shark and Megalodon, the biggest predatory shark that has ever roamed the world's oceans.
Effective atomic interactions in complex materials picked up by on-the-fly machine-learning At the atomic scale materials can show a rich palette of dynamic behaviour, which directly affects the physical properties of these materials. For many years, it has been a dream to describe these dynamics in complex materials at various temperatures using computer simulations.
Physicists develop new method to prove quantum entanglement One of the essential features required for the realization of a quantum computer is quantum entanglement. A team of physicists from the University of Vienna and the Austrian Academy of Sciences (ÖAW) introduces a novel technique to detect entanglement even in large-scale quantum systems with unprecedented efficiency.
Antidepressant treatment, not only depression per se, can lead to reductions in behavioral and neural responses to pain empathy Depression is a disorder that often comes along with strong impairments of social functioning. Until recently, researchers assumed that acute episodes of depression also impair empathy, an essential skill for successful social interactions and understanding others.
