A newly developed rapid test needs only a few seconds to reliably detect pathogens such as SARS-CoV-2. It is based on specially designed magnetic nanoparticles. The current rapid tests for diagnosing infectious diseases are speedy, but not really fast. For example, antigen self-tests, PCR tests or ELISA tests for coronavirus take 15 minutes to several hours before a reliable result is available.

New findings lay the foundation for the search for dark matter How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including Technical University of Munich (TUM) scientists has now measured for the first time the survival rate of antihelium nuclei from the depths of the galaxy - a necessary prerequisite for the indirect search for Dark Matter.

In future it will be possible to incorporate data from deep space telescopes into the underlying atomic models with a high degree of reliability Very hot gas, as found in the sun's corona or in close proximity to black holes, emits very intense x-rays. It reveals the locally prevailing physical conditions, such as temperature and density.

Scientists simulate a whole family of universes with curvature in ultracold quantum gases According to Einstein's general theory of relativity, space and time are inseparable. In our universe - which is hardly measurably curved - the structure of this spacetime is predetermined. Scientists at Heidelberg University have now succeeded in realizing an effective spacetime in a laboratory experiment that can be manipulated.

Chemists at the University of Münster develop method for simple production of vicinal diamines Among the most common structures relevant to the function of biologically active molecules, natural products and drugs are so-called vicinal diamines - in particular, unsymmetrically constructed diamines. Vicinal diamines contain two functional atomic groups responsible for the substance properties, each with a nitrogen atom bonded to two neighbouring carbon atoms.

Researchers at Freie Universität Berlin took part in a new study on chiral molecules recently published in "Science Advances" In a recent study, researchers at Freie Universität Berlin, the DESY research center in Hamburg, Kiel University, and Kansas State University have shown how light can turn a planar molecule into a chiral molecule with just one particular handedness, providing a solution to the long-standing problem of absolute asymmetric synthesis.

Unconventional computing combines Brownian computing with reservoir computing / First prototype developed A large percentage of energy used today is consumed in the form of electrical power for processing and storing data and for running the relevant terminal equipment and devices. According to predictions, the level of energy used for these purposes will increase even further in the future.

Patient study demonstrates benefits of dark-field X-ray technology A research team at the Technical University of Munich (TUM) has, for the first time, produced dark-field X-ray images of patients infected with the corona virus. In contrast to conventional X-ray images, dark-field images visualize the microstructure of the lung tissue, thereby providing additional information.

Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and are constantly increasing. However, if chips, processors and the like are based on electricity, there are limits to miniaturization. Physicists are therefore working on alternative ways of transporting information, such as about spin waves, also called magnons, for example.

Modern solar cells work with thin layers of semiconductors that convert sunlight into electrical energy. The key to increasing their efficiency even further lies in the composition and structure of the material. Due to the way the material is manufactured, it can have defects that have a disruptive effect.

Researchers in Mainz and Kyushu established a novel strategy for the generation of highly energetic UV light Many photochemical processes rely on UV light from inefficient or toxic light sources that the LED technology cannot replace for technical reasons. An international team of scientists led by Professor Christoph Kerzig of Johannes Gutenberg University Mainz (JGU) in Germany and Professor Nobuhiro Yanai of Kyushu University in Japan has now developed the first molecular system for the conversion of blue light into high-energy UV photons with wavelengths below 315 nanometers.

Researchers decrypt transport dynamics of porous media What laws govern how chemicals pass through filters? How do droplets of oil move through layers of stone? How do blood cells travel through a living organism? A team of researchers led by the Technical University of Munich (TUM) and the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) has discovered how pore space geometry impacts transport of substances through fluids.

International team observes innermost structure of quasar 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active types of galaxy centres. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, presents new observations of the first quasar ever identified.

Researchers discover an important clue as to what mechanism drives the solar wind Using observational data from the U.S. weather satellites GOES, a team of researchers led by the Max Planck Institute for Solar System Research (MPS) in Germany has taken an important step toward unlocking one of the Sun-s most persevering secrets: How does our star launch the particles constituting the solar wind into space? The data provide a unique view of a key region in the solar corona to which researchers have had little access so far.

International team observes the innermost structure of the jet of 3C 273 At the core of almost every galaxy is a supermassive black hole. But there are many different types. Quasars, for example, are one of the brightest and most active varieties of galactic centers. An international group, including researchers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, presents new observations of the first quasar ever identified.

A team from the Friedrich Schiller University Jena has set up a new streak camera on ID16B, which can measure very fast kinetic phenomena present in light emission after receiving an X-ray pulse. The camera is now available to the user community to study complex carrier dynamics with spatio-temporal resolutions.

Neutrons from FRM II expose crystal structure of carbonic acid The existence of carbonic acid has long been the subject of debate: theoretically real, but practically impossible to detect. That is because the compound decomposes at the Earth's surface. A German-Chinese team of researchers working at the FRM II Research Neutron Source at the Technical University of Munich (TUM) has now made the crystalline structure of carbonic acid molecules visible for the first time.

Physicists at JGU discovered: Antiferromagnets are suitable for transporting spin waves over long distances Smaller, faster, more powerful: The demands on microelectronic devices are high and continue to rise. However, if chips, processors and the like are based on electric current, there are limits to miniaturization.

A team of German and Spanish researchers from Valencia, Münster, Augsburg, Berlin and Munich have succeeded in controlling individual light quanta to an extremely high degree of precision. In the "Nature Communications" journal, the researchers report how, by means of a soundwave, they switch individual photons on a chip back and forth between two outputs at gigahertz frequencies.

Numerical simulation representing the curvature of spacetime during the merger of the two black holes. When black holes collide in the universe, the clash shakes up space and time: the amount of energy released during the merger is so great that it causes space-time to oscillate, similar to waves on the surface of water.
