Structural color printing creates new pathways for medical diagnostics and miniaturized sensors. Microfluidic devices use tiny spaces to manipulate very small quantities of liquids and gasses by taking advantage of the properties they exhibit at the microscale. They have demonstrated usefulness in applications from inkjet printing to chemical analysis and have great potential in personal medicine, where they can miniaturize many tests that now require a full lab, lending them the name lab-on-a-chip. Researchers at Kyoto University’s Institute for Integrated…
Thermal insulation is not only important for buildings, but also in quantum technologies. While insulation panels around a house keep the heat inside, quantum devices require insulation against heat from the outside world, as many quantum effects are only stable at low temperatures. What is needed are materials with extremely low thermal conductivity that are also compatible with the materials used in quantum technology. Novel sintering process A team led by Dr Klaus Habicht from HZB has now taken a…
Electronic nematicity, thought to be an ingredient in high temperature superconductivity, is primarily spin driven in FeSe finds a study in Nature Physics. Researchers from PSI’s Spectroscopy of Quantum Materials group together with scientists from Beijing Normal University have solved a puzzle at the forefront of research into iron-based superconductors: the origin of FeSe’s electronic nematicity. Using Resonant inelastic X-ray scattering (RIXS) at the Swiss Light Source (SLS), they discovered that, surprisingly, this electronic phenomenon is primarily spin driven. Electronic…
Novel surface treatment developed at UCLA stops microbes from adhering to medical devices like catheters and stents. A hospital or medical clinic might be the last place you’d expect to pick up a nasty infection, but approximately 1.7 million Americans do each year, resulting in nearly 100,000 deaths from infection-related complications and roughly $30 billion in direct medical costs. The biggest culprits, experts say — accounting for two-thirds of these infections — are medical devices like catheters, stents, heart valves…
Coral reef fish breed more successfully if motorboat noise is reduced, new research shows. Scientists introduced “traffic calming” on three reefs for an entire breeding season – cutting the number of boats within 100m, and reducing the speed of those within that distance. They then tracked the breeding of fish called spiny chromis – and found 65% of nests on quieter reefs still contained offspring at the end of the season, compared to 40% on reefs with busy motorboat traffic….
Satellites and drones can provide key information to protect pollinators, researchers say. Their study examines new ways of using these technologies to track the availability of flowers, and says this could be combined with behavioural studies to see the world through the eyes of insects. The flowers available to insects vary from day to day and place to place, and human activity is changing landscapes in ways that affect all pollinators. The University of Exeter research team, supported by the…
Researchers at the University of Gothenburg have developed several new varieties of wheat that tolerate soils with higher salt concentrations. After having mutated a wheat variety from Bangladesh, they now have a wheat with seeds that weigh three times more and that germinate almost twice as often as the original variety. The wheat, which grows in fields near the coast in Bangladesh, has a certain tolerance to salt in soils, which is important when more and more farmland around the…
A team of researchers from Bordeaux, Augsburg and Bayreuth has studied 61 different metals over the course of multiple years. The results have been published in the prestigious journal “Nature Sustainability“ – The most significant finding was that the raw materials critical to modern technology, in particular, have a relatively short usage period. How long are metallic and mineral raw materials usable in the economic cycle – and when do they dissipate? Researchers from Bordeaux, Augsburg, and Bayreuth, answer these…
New insights into understanding turbulence in fusion plasmas. Results shown in this article were published in a scientific journal of the Nature publishing group, Scientific Reports. In order to achieve a fusion power plant, it is necessary to stably confine a plasma of more than 100 million degrees Celsius in a magnetic field and maintain it for a long time. A research group led by Assistant Professor Naoki Kenmochi, Professor Katsumi Ida, and Associate Professor Tokihiko Tokuzawa of the National…
Since the discovery of the chloride ion channel ASOR three years ago, researchers have been searching for its biological functions. Now, the team led by Prof. Thomas Jentsch at the FMP and MDC in Berlin discovered that ASOR is essential for the shrinkage of macropinosomes – particularly large vesicles that take up large amounts of extracellular fluid, including ions and proteins, in a non-specific manner. This process is especially important for certain immune and cancer cells. Indeed, under nutrient-poor conditions,…
As NASA’s James Webb Space Telescope moves through the final phases of commissioning its science instruments, we have also begun working on technical operations of the observatory. While the telescope moves through space, it will constantly find distant stars and galaxies and point at them with extreme precision to acquire images and spectra. However, we also plan to observe planets and their satellites, asteroids, and comets in our solar system, which move across the background stars of our galaxy. Webb needs to…
Scientists have synthesized the first belt-shaped molecular nanocarbon with a twisted Möbius band topology—a Möbius carbon nanobelt—that paves the way for the development of nanocarbon materials with complex topological structures. Obtaining structurally uniform nanocarbons—ideally as single molecules—is a great challenge in the field of nanocarbon science in order to properly relate structure and function. Thus, the construction of structurally uniform nanocarbons is crucial for the development of functional materials in nanotechnology, electronics, optics, and biomedical applications. An important tool for…
MBARI’s autonomous technology uses eDNA to survey biodiversity. In a major step forward for monitoring the biodiversity of marine systems, a new study published today in Environmental DNA details how MBARI researchers are using autonomous underwater robots to sample environmental DNA (eDNA). eDNA allows scientists to detect the presence of aquatic species from the tiny bits of genetic material they leave behind. This DNA soup offers clues about biodiversity changes in sensitive areas, the presence of rare or endangered species,…
Researchers at the 5th Physical Institute of the University of Stuttgart have verified a novel binding mechanism forming a molecule between a tiny charged particle and in atomic measures gigantic Rydberg atom. The scientists could observe spatially resolved the molecule with the help of a self-build ion microscope. The well-known journal “Nature” published the results on May 18, 2022. When single particles like atoms and ions bond, molecules emerge. Such bonds between to particles can arise if they have for…
Strong innovations: “Reference-factory.H2”, intelligent machine components in adaptive process chains, human-robot interaction and soft robotics demonstrate solutions for industrial green hydrogen, the factory of the future, household, and nursing. Reference-factory.H2: advancing the industrial production of electrolyzers and fuel cells Anyone who considers acquiring a photovoltaic system for their domestic roof may con-sider a significantly lower budget than ten or fifteen years ago, in spite of current price fluctuations. Highly efficient industrial large series production realizes the lower prices. An individual…
– Negatively charged Polymer proves effective. A large number of viruses are known to make life difficult for both humans and animals. While broad-spectrum antibiotics can offer protection against a wide variety of bacteria, there are currently no analogous clinically available broad-spectrum antiviral agents. An international research team has now shown that polystyrene sulfonate (PSS) has the potential to be used in the prevention of viral infections – not only in the fight against the SARS-CoV-2 and cold viruses, but…
