Researchers at the Max Planck Institute for Intelligent Systems have discovered a new mechanism of self-organization of active matter. When photochemically active nanoparticles are enclosed at high density within a drop and are exposed to UV light, a self-organized flow pattern emerges by spontaneous symmetry breaking. Furthermore, each drop communicates with neighbouring drops by exchanging chemicals, and coordination of their internal flows occurs – even when far apart.
Communication and organized behaviour is considered to be the quintessence of living systems. For example, understanding how cellular patterns form is one of...
For the first time, an international team of researchers succeeded in demonstrating the previously unknown structure of magnetic skyrmion tubes in 3D. This knowledge makes it possible to better understand the formation and destruction of skyrmions and to use the magnetic structures in so-called spintronic storage devices.
Scientists have never before succeeded in making so-called skyrmions – 100 nanometre small vortex structures that occur in magnetic material – visible in 3D....
A specific fibril tip shape design is the key to achieving elastic dry fibril adhesives with super liquid repellency. This new bioinspired material opens up many possibilities for use, as it prevents any form of liquid droplet or layer from hindering or degrading its adhesion.
Scientists at the Max Planck Institute for Intelligent Systems (MPI-IS) in Stuttgart have developed a bioinspired reversible dry adhesive material that is able...
With the help of NASA’s Spitzer Space Telescope, an international team of researchers has confirmed that the cosmic object OJ 287 is a distant galaxy with a binary system of two supermassive black holes in its centre, which are orbiting each other. With the measurement data that the scientists present in today’s issue of the “Astrophysical Journal Letters”, they also verify the “no-hair” theorem of black holes. Astrophysicists from the Friedrich Schiller University Jena are among the authors of the study (https://doi.org/10.3847/2041-8213/ab79a4)
It took more than 100 years until the existence of gravitational waves predicted by Albert Einstein in 1915 as part of his general theory of relativity was...
Data transmission that works with magnetic waves instead of electric currents can be the basis for future information technologies. Some years ago, researchers at the University of Münster reached a new quantum state of magnetic particles at room temperature – a Bose-Einstein condensate. In a new study they show that the particles in the condensate behave repulsively, which leads to its stabilization. In this way, they resolve a long-standing contradiction between theory and practice. The study was published in the journal "Nature Communications".
Data transmission that works by means of magnetic waves instead of electric currents – for many scientists, this is the basis of future technologies that will...
The destructive force of a tornado occurs due to the extremely high rotational speeds in its center, which is called “vortex”. Surprisingly, similar effects as in such storms are predicted for light that travels along an atomically smooth gold surface. This light can exhibit angular momentum and vortices. Researchers at the Universities of Stuttgart and Duisburg-Essen and the University of Melbourne (Australia) have now succeeded for the first time in filming these vortex patterns on the nanometer scale, which are named "skyrmions" after their discoverer Tony Skyrme. The journal Science reports this groundbreaking work in its issue of April 24, 2020.
When a figure skater starts to perform a pirouette and raises her arms, she turns around her own axis increasingly faster due to the conservation of angular...
The use of mechanical ventilation can save lives – and not just for COVID-19 patients who develop severe respiratory problems. But at the same time, the ventilation pressure puts immense stress on delicate lung tissue. Especially for patients with preexisting lung damage, the use of ventilators can prove deadly. A computational lung model that’s been developed by the Technical University of Munich (TUM) can be used to reduce damage caused by mechanical ventilation – and could increase survival rates for patients significantly.
For patients suffering from acute lung failure (Acute Respiratory Distress Syndrome, ARDS), mechanical ventilation is a lifesaving treatment.
Researchers from University of Copenhagen have discovered a new way of developing topological superconductivity that may provide a useful route toward the use of Majorana zero modes as the foundation of qubits for quantum information.

Scientists at TU Bergakademie Freiberg are currently testing a prototype of a pressure-controlled emergency ventilator. The device, which can be built with simple tools and is easy to maintain, could be used primarily in developing countries for the ventilation of emergency patients suffering from lung diseases.
To this end, the mine rescue team of TU Bergakademie Freiberg and the Institute for Machine Elements, Design and Production have combined their expertise.
