An international team of astrophysicists has made a puzzling discovery while analyzing certain star clusters. The University of Bonn played a major role in the study. The finding challenges Newton’s laws of gravity, the researchers write in their publication. Instead, the observations are consistent with the predictions of an alternative theory of gravity. However, this is controversial among experts. The results have now been published in the Monthly Notices of the Royal Astronomical Society. In their work, the researchers investigated…
International research team from pharmacy and chemistry develops an estrogen that can be switched on and off. Unwanted side effects in the body, drug resistance or environmentally harmful residues – drugs not only cure diseases or relieve pain, but can also have negative effects on people or the environment. This could be reduced by medical compounds that are only active at the site of an illness in the body. A research team from Pharmacy and Chemistry at Kiel University (CAU),…
A 3D-printed device in a tank of water braids nanowires and moves microparticles. The next generation of phones and wireless devices are going to need new antennae to access higher and higher frequency ranges. One way to make antennae that work at tens of gigahertz — the frequencies needed for 5G and higher devices — is to braid filaments about 1 micrometer in diameter. But today’s industrial fabrication techniques won’t work on fibers that small. Now a team of researchers…
… may one day help with laundry. New research from Carnegie Mellon University’s Robotics Institute can help robots feel layers of cloth rather than relying on computer vision tools to only see it. The work could allow robots to assist people with household tasks like folding laundry. Humans use their senses of sight and touch to grab a glass or pick up a piece of cloth. It is so routine that little thought goes into it. For robots, however, these tasks are…
Anisoprint arrived at Jacobs University Bremen. Starting in September 2022, 3D printing solution provider Anisoprint deployed their Research and Development Team at Jacobs University Bremen. The main focus of the partnership? Fostering research and development of composites manufacturing with Continuous Fiber Coextrusion (CFC) technology, and establishing a research environment for 3D printing technologies on the university campus in Bremen, Germany. Following the announcement of the cooperation between Anisoprint and Jacobs University, the startup team moved their R&D operations to Bremen…
For the first time, physicists have observed novel quantum effects in a topological insulator at room temperature. This breakthrough, published as the cover article of the October issue of Nature Materials, came when Princeton scientists explored a topological material based on the element bismuth. The scientists have used topological insulators to demonstrate quantum effects for more than a decade, but this experiment is the first time these effects have been observed at room temperature. Typically, inducing and observing quantum states…
When algae, mussels or barnacles settle on ship hulls, this can lead to billions of euros worth of damage. To counteract this, they are treated with antifouling coatings. A scientist at the Leibniz Centre for Tropical Marine Research (ZMT) has now investigated the extent to which newly developed antifouling coatings could be used to curb algal growth, which often affects coral larvae as they settle and develop. The results of the study were published in the journal Scientific Reports. Tropical…
MHH research team finds two promising AAV capsid variants for gene therapy in the liver. There are numerous severe, hardly treatable monogenetic diseases that are caused by a defect in a single gene – also in the liver. These include the blood coagulation disorders haemophilia A or B or the metabolic disease phenylketonuria. Gene therapies could help here, in which intact genes are transported directly into the cell as a “drug”. In Europe, some gene therapies have already been approved…
University of Tübingen astrophysicists combine measurements from different telescopes to uncover mysterious object hidden in a supernova cloud. The lightest neutron star so far found is located at the center of the supernova remnant HESS J1731-347. Dr. Victor Doroshenko, Dr. Valery Suleimanov, Dr. Gerd Pühlhofer and Professor Andrea Santangelo from the High Energy Astrophysics section of the University of Tübingen’s Institute of Astronomy and Astrophysics discovered the unusual object with the help of X-ray telescopes in space. According to calculations…
Forty years ago, physicists at the Max Planck Institute for Plasma Physics found a new plasma state that could be particularly suitable for energy production: the H-mode. On 8 November 1982, the corresponding paper was published, giving fusion research a worldwide boost. To this day, the investigation of the H-mode is one of their most important fields of work. The breakthrough came on a Thursday when – as often before – plasmas with neutral beam heating were to be studied…
The Yield consortium uses satellite data and artificial intelligence to reliably predict agricultural yields. In collaboration with BASF Digital Farming, John Deere, and Munich Re, DFKI develops predictive models for selected arable crops in the focus regions of Europe, South and North America. Later models will extend to other relevant crops and growing regions. How can artificial intelligence help the agricultural sector? Environmental challenges in our world today are materializing on a global scale, in the form of food crises,…
A KIT team has analyzed the extraction of lithium from thermal water resources in Germany – feasible extraction volumes and time horizon limit the potential. Pumping up thermal water, separating lithium, and using it to produce batteries for electric mobility – the idea of lithium as an environmentally compatible and regionally available by-product of geothermal energy plants appears highly promising. However, it has not been clear so far whether domestic lithium extraction is really worthwhile. A team of researchers from…
Team of three researchers with participation from Humboldt-Universität to receive 8 million euros in funding from the European Research Council. Both a future tap-proof quantum Internet and the quantum computer use principles and methods of quantum optics, which deals with the interaction of photons, i.e. light particles, with quantum emitters such as atoms or molecules. Particular progress has recently been made in the field of nonlinear quantum optics. There, one investigates photons that attract or repel each other in a…
… could enable circular home furnishings and building materials. Plastics used in home furnishings and constructions materials could be replaced with a new kind of wood-based degradable plastic with semi-structural strength. Unlike thermoplastic, the material can be broken down without harm to the environment, researchers in Sweden have reported. One of the goals of renewable wood composite development is to make materials strong enough to replace fossil-based materials used in home construction and furnishing, such as bathroom cabinets, doors, wall-boards…
Physicists have created the first Bose-Einstein condensate — the mysterious ”‘fifth state” of matter — made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle properties like charge and spin. For decades, it was unknown whether they could undergo Bose-Einstein condensation in the same way as real particles, and it now appears that they can. The finding is set to have a significant impact on the development of quantum technologies including quantum computing….
Using a new technology, researchers hope to create better control systems for prosthetic limbs. Using a simple set of magnets, MIT researchers have come up with a sophisticated way to monitor muscle movements, which they hope will make it easier for people with amputations to control their prosthetic limbs. In a new pair of papers, the researchers demonstrated the accuracy and safety of their magnet-based system, which can track the length of muscles during movement. The studies, performed in animals,…
