How do simple creatures manage to move to a specific place? Artificial intelligence and a physical model from TU Wien can now explain this. How is it possible to move in the desired direction without a brain or nervous system? Single-celled organisms apparently manage this feat without any problems: for example, they can swim towards food with the help of small flagellar tails.
T cells use their antigen receptors like sticky fingers - a team from TU Wien and MedUni Vienna was able to observe them doing so. T-cells play a central role in our immune system: by means of their so-called T-cell receptors (TCR) they make out dangerous invaders or cancer cells in the body and then trigger an immune reaction.
The acidity of molecules can be easily determined, but until now it was not possible to measure this important property for atoms on a surface. With a new microscopy technique from the Vienna University of Technology (TU Wien), this has now been achieved. The degree of acidity or alkalinity of a substance is crucial for its chemical behavior.
Is it possible to transmit information through a material in the form of electron spins? New measurements show: not in the way that scientists had been working on for decades. It is an old dream of solid-state physics: "spin liquids" are a hypothetical state of matter with exotic magnetic properties.
In a new study, an international team led by Sebastian Stumpf from the University of Vienna describes a fossil skeleton of an ancient shark, which is assigned to a new, previously unknown genus and species. This rare fossil find comes from the Kimmeridge Clay Formation in England, a series of sedimentary rocks that was formed in a shallow, tropical-subtropical sea during the Upper Jurassic, about 150 million years ago.
The extent to which the composition of the microbiome of apples and oil pumpkins depends on the geographical location and what insights can be derived from this for breeding, health and shelf life of the fruits is shown in two recent publications by researchers at TU Graz. Additional pictures for download at the end in the text We refer to the microbiome as the community of microorganisms that exist in or on all organisms, including bacteria and fungi.
Human childbirth is comparatively difficult because our babies' heads are large relative to our birth canals. This tight "fetopelvic" fit increases the risk of obstructed labor, which in turn has potentially dire outcomes for both mother and child. It has long been thought that bipedalism prevents further widening of the human pelvis.
With an elephant-friendly alternative to ivory, developed by TU Wien and Cubicure, old artefacts can be restored with high precision. For centuries, ivory was often used to make art objects. But to protect elephant populations, the ivory trade was banned internationally in 1989. To restore ivory parts of old art objects, one must therefore resort to substitute materials - such as bones, shells or plastic.
Researchers at Utrecht University and at TU Wien (Vienna) create special light waves that can penetrate even opaque materials as if the material was not even there. Why is sugar not transparent? Because light that penetrates a piece of sugar is scattered, altered and deflected in a highly complicated way.
A sulfosugar from green vegetables promotes the growth of important gut bacteria An international team of scientists led by microbiologists Alexander Loy from the University of Vienna and David Schleheck from the University of Konstanz has uncovered new metabolic capabilities of gut bacteria. For the first time, the researchers have analyzed how microbes in the gut process the plant-based, sulfur-containing sugar sulfoquinovose.
How can we remove heat from computer chips as fast as possible' At TU Wien, a metal compound has now been identified that is particularly well suited for this purpose. A thermos bottle has the task of preserving the temperature - but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed.
Researchers at TU Graz and the University of Graz, together with experts from France, have succeeded in imaging surface phonons in 3D for the first time. This success could accelerate the development of new, efficient nanotechnologies. Whether for microscopy, data storage or sensor technology, many advanced technological applications that require specific functions rely on the structure of the electromagnetic field near the surfaces of materials.
Carbonized plants contain harmful free radicals Every year, an estimated four percent of the world's vegetated land surface burns, leaving more than 250 megatons of carbonized plants behind. For the first time, a study by the University of Vienna has now recorded elevated concentrations of environmentally persistent free radicals (EPFR) in these charcoals - in some cases even up to five years after the fire.
With a total length of up to 5.5m, the tiger shark is one of the largest predatory sharks known today. This shark is a cosmopolitan species occurring in all oceans worldwide. It is characterized by a striped pattern on its back, which is well marked in juveniles but usually fades in adults.
2D materials have triggered a boom in materials research. Now it turns out that exciting effects occur when two such layered materials are stacked and slightly twisted. The discovery of the material graphene, which consists of only one layer of carbon atoms, was the starting signal for a global race: Today, so-called "2D materials" are produced, made of different types of atoms.
International survey shows different perceptions in science and practice To minimize negative impacts of agriculture on biodiversity and related ecosystem services, "biodiversity-friendly" management is needed. Why scientific results are rarely translated into agricultural practice could be explained by their different perceptions of agricultural biodiversity, according to the results of a recent survey of European scientists and farmers.
The study results are based on investigations of repeated mass movements and are expected to benefit planning, maintenance, and development of transportation infrastructure in affected areas. Mass movements such as landslides and hill-slope debris flows cause billions of euros in economic damage around the world every year.
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population's response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors that help to maintain high perceived levels of health during restrictions.
New measurements have solved a mystery in solid state physics: How is it that certain metals do not seem to adhere to the valid rules? We all have a clear picture in mind when we think of metals: We think of solid, unbreakable objects that conduct electricity and exhibit a typical metallic sheen. The behaviour of classical metals, for example their electrical conductivity, can be explained with well-known, well-tested physical theories.
An international team of scientists with Fridgeir Grímsson from the University of Vienna has found a previously unknown fossil fly species in old lake sediments of the Messel Pit, a UNESCO World Heritage Site in Germany. In the stomach of the fossil insect, pollen from various plants could be detected, which allows rare insights into the feeding behavior, the ecology and the role of the fly as a pollinator.
