Aston Institute of Photonic Research academics are part of a team that sent data at a rate of 402 terabits per second This beats their previous record of 301 terabits per second They constructed the first optical transmission system covering six wavelength bands. Aston University researchers are part of a team that has sent data at a record rate of 402 terabits per second using commercially available optical fibre. This beats their previous record, announced in March 2024, of 301…
A research team led by Professor Hyoung Seop Kim from the Graduate Institute of Ferrous & Eco Materials Technology and the Department of Materials Science and Engineering and Jeong Ah Lee, a PhD candidate, from the Department of Materials Science and Engineering, in recent collaboration with Professor Figueiredo from Universidade Federal de Minas Gerais’s Department of Metallurgical and Materials Engineering in Brazil, has developed an optimal artificial intelligence model to predict the yield strength of various metals, effectively addressing traditional…
When ultrafast electrons are deflected, they emit light – synchrotron radiation. This is used in so called storage rings in which magnets force the particles onto a closed path. This light is longitudinally incoherent and consists of a broad spectrum of wavelengths. Its high brilliance makes it an excellent tool for materials research. Monochromators can be used to pick out individual wavelengths from the spectrum, but this reduces the radiant power by many orders of magnitude to values of a…
Together with colleagues from Augsburg, Bonn, Cologne, Dresden, Geneva and Prince George (Canada), Professor Zhe Wang from the Department of Physics at TU Dortmund University has discovered an exotic quantum state of the matter in a solid-state compound – repulsively bound magnons. This observation is so spectacular for fundamental research in the field of quantum physics that it has been published in the renowned journal “Nature”. Atoms, molecules or solids that are formed by attractive forces between their constituents are…
Heidelberg chemists characterise new basic structure in the field of aromaticity. The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore unknown. The research team led by Prof. Dr Lutz Greb, a scientist at Heidelberg University’s Institute of Inorganic Chemistry, recently succeeded in isolating such a metal ring and describing it in full. Aromatic compounds, or aromatics, are a substance class in…
A new study led by researchers at UCL and the University of Sheffield, has demonstrated the potential of stem cell therapy to treat those with Hirschsprung disease. Hirschsprung disease is a rare condition where some nerve cells are missing in the large intestine. This means the intestine doesn’t contract and can’t move stool, meaning that it can become blocked. This can cause constipation and sometimes lead to a serious bowel infection called enterocolitis. Around 1 in 5000 babies are born…
Monoclonal antibody developed from blood of recovering patients. The National Institutes of Health (NIH) is sponsoring a clinical trial to evaluate the safety of an investigational monoclonal antibody to treat enterovirus D68 (EV-D68), which can cause severe respiratory and neurological diseases such as acute flaccid myelitis (AFM) – similar to polio. Scientists are striving to better understand AFM, which has emerged in the United States with spikes in cases every other year, primarily in the late-summer months over the last…
Research shows deep sea organisms have unique lipid structures to help them survive. The bottom of the ocean is not hospitable: there is no light; the temperature is freezing cold; and the pressure of all the water above will literally crush you. The animals that live at this depth have developed biophysical adaptations that allow them to survive in these harsh conditions. What are these adaptations and how did they develop? University of California San Diego Assistant Professor of Chemistry…
Researchers at LJI and Columbia University uncover exactly how a neutralizing antibody blocks measles virus infection. What happens when measles virus meets a human cell? The viral machinery unfolds in just the right way to reveal key pieces that let it fuse itself into the host cell membrane. Once the fusion process is complete, the host cell is a goner. It belongs to the virus now. Scientists in the La Jolla Institute for Immunology (LJI) Center for Vaccine Innovation are…
Study shows Manipulation Possibilities. On behalf of the German Federal Office for Information Security (BSI), experts from the IHP – Leibniz Institute for High Performance Microelectronics prepared the study “Analysis of Hardware Manipulations in Distributed Manufacturing Processes (PANDA)”. The result: Safety properties or functionality can be negatively affected in all sub-steps. IHP scientist Hon. Prof. Zoya Dyka shows the BSI employees where the mainboard of a laptop could be manipulated.(c) Franziska Wegner / IHP Hardware Trojans could become a threat….
HIRI researchers introduce novel approach to DNA transformation and genetic mutation of bacteria. Bacteria possess unique traits with great potential for benefiting society. However, current genetic engineering methods to harness these advantages are limited to a small fraction of bacterial species. A team led by the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg has now introduced a novel approach that can make many more bacteria amenable to genetic engineering. Their method, called IMPRINT, uses cell-free systems to enhance…
Würzburg researchers from the Bavarian initiative Solar Technologies Go Hybrid are reporting progress on the road to more efficient utilisation of solar energy: they have developed an innovative light-harvesting system. In order to convert sunlight into electricity or other forms of energy as efficiently as possible, the very first step is an efficient light-harvesting system. Ideally, this should be panchromatic, i.e. absorb the entire spectrum of visible light. The light-collecting antennae of plants and bacteria are a model for this….
Hand prostheses that restore tactile sensitivity to amputees. Sensors capable of detecting diseases prior to outbreaks. These applications could soon become part of conventional treatment thanks to microchips implanted in the body. At Fraunhofer IZM, the Technologies for Bioelectronics working group is busy developing ultra-thin biocompatible coatings for bioelectronics implants. The core aim is to enable decade-long functionality of miniature implants without the need for surgical interventions. Compared to current forms of diagnosis and treatment that are based on conventional…
A research team from the University of Jena has developed a small optical lens, only a few millimetres in size, whose refractive behaviour changes in the presence of gas. As reported by the researchers in the journal Nature Communications, this “intelligent” behaviour of the micro-lens is enabled by the hybrid glass material from which it is made. The molecular structure of the lens consists of a three-dimensional lattice with cavities that can accommodate gas molecules, thereby affecting the optical properties…
Makino and Fraunhofer ILT expand the possibilities of Additive Manufacturing. Makino and the Fraunhofer Institute for Laser Technology ILT are using EHLA and EHLA3D to redefine the boundaries of Additive Manufacturing. By integrating EHLA3D into a five-axis CNC platform, they have developed a process that can efficiently produce, coat or repair complex geometries with high-strength materials. Result of the collaboration: shorter production times and extended component life in critical industries, while laying the foundations for future innovation in the circular…
In a single leap from tabletop to the microscale, engineers at Stanford have produced the world’s first practical titanium-sapphire laser on a chip, democratizing a once-exclusive technology. As lasers go, those made of Titanium-sapphire (Ti:sapphire) are considered to have “unmatched” performance. They are indispensable in many fields, including cutting-edge quantum optics, spectroscopy, and neuroscience. But that performance comes at a steep price. Ti:sapphire lasers are big, on the order of cubic feet in volume. They are expensive, costing hundreds of…
