Electrons have an intrinsic angular momentum, the so-called spin, which means that they can align themselves along a magnetic field, much like a compass needle. In addition to the electric charge of electrons, which determines their behaviour in electronic circuits, their spin is increasingly used for storing and processing data. Already now, one can buy MRAM memory elements (magnetic random access memories), in which information is stored in very small but still classical magnets – that is, containing very many…
Researchers at the University of Gothenburg have developed an AI model that increases the potential for detecting cancer through sugar analyses. The AI model is faster and better at finding abnormalities than the current semi-manual method. Glycans, or structures of sugar molecules in our cells, can be measured by mass spectrometry. One important use is that the structures can indicate different forms of cancer in the cells. However, the data from the mass spectrometer measurement must be carefully analysed by…
In humankind’s ever-ticking pursuit of perfection, scientists have developed an atomic clock that is more precise and accurate than any clock previously created. The new clock was built by researchers at JILA, a joint institution of the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder. Enabling pinpoint navigation in the vast expanse of space as well as searches for new particles, this clock is the latest to transcend mere timekeeping. With their increased precision, these…
Researchers at Fraunhofer IPM have developed a contactless flow measurement method based on magnetic fields. For the first time, they have been able to show the quantitative impact of the flow profile on the magnetic signal. This opens up new possibilities for improving the measurement method. The results were recently published in the “Journal of Applied Physics”. There are many manufacturing processes across various industries where flowing liquids play a key role. Controlling or automating such processes requires reliable data…
Interaction with autonomous driving. Optimizing communication between vehicle and driver as a function of the degree of automation is the objective of a research project conducted by Fraunhofer in collaboration with other companies. The researchers are combining sensors for monitoring the vehicle interior with language models to form what are known as vision language models. They are designed to increase the convenience and safety of cars in the future. “Warning, if you keep reading now, you may become nauseous on…
Fraunhofer researchers have developed a method of creating biogenic construction materials based on cyanobacteria. The bacteria multiply in a nutrient solution, driven by photosynthesis. When aggregates and fillers such as sand, basalt, or renewable raw materials are added, rock-like solid structures are produced. Unlike traditional concrete production, this process does not emit any carbon dioxide, which is harmful to the environment. Instead, the carbon dioxide is bound inside the material itself. The construction industry has a problem. Cement, the main…
DFKI researchers are in the finals of XPRIZE Rainforest. Researchers from DFKI Niedersachsen, together with doctoral students from the Applied Artificial Intelligence department at the University of Oldenburg, have reached the finals of XPRIZE Rainforest, a global competition that promotes innovative technologies for researching and conserving biodiversity in tropical rainforests. As part of the Brazilian Team, they are developing an AI-system that filters out the acoustic signals that ecologists need to determine species diversity from a large number of audio…
To prevent proteins from being damaged during cellular stress, they are concentrated in so-called stress granules. Scientists from the department of Cellular Biochemistry at the Max Planck Institute of Biochemistry have now been able to show for the first time that the protein Urm1 has a critical role in this process. In yeast cells, the ubiquitin-like protein facilitates the onset of phase separation and thus the formation of stress granules. The results of the study were published in the scientific…
From smart electric meters to tachometers, wherever consumption or mileage is read out electronically, the data transmitted should not be open to manipulation. That is especially true for verification of payment transfers made via credit card. Researchers at the Fraunhofer Institute for Photonic Microsystems IPMS have developed a solution that makes it possible to configure the functions of security elements to address this issue after manufacturing, reliably and cost-effectively providing them with multidimensional protection. From payment transfers to smart electric…
… at depths of 3,000 meters off Svalbard. Study of the Jøtul hydrothermal field, discovered in 2022, has now been published. Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered. An international team of researchers from Bremen…
Hydrogen generated with the power of the sun could largely replace fossil fuels in the future, helping to lower carbon emissions. In the Neo-PEC joint research project, Fraunhofer specialists have developed a tandem module that is self-sufficient and reliable at producing solar-generated green hydrogen. Hydrogen is a key starting point in transforming industrial processes for lower climate impact. However, a fuel that combusts without releasing CO2 should also be produced without any carbon footprint if at all possible. One classic…
Reducing semiconductor laser production costs by 1/6 with quantum dot lasers for optical communications. Using 6-inch substrates instead of 2-inch: time reduction and mass production achieved. South Korean researchers have successfully developed technology to mass-produce quantum dot lasers, widely used in data centers and quantum communications. This breakthrough paves the way for reducing the production cost of semiconductor lasers to one-sixth of the current cost. Metal-Organic Chemical Vapor Deposition (MOCVD).

A team of researchers led by the University of California San Diego has developed a soft, stretchy electronic device capable of simulating the feeling of pressure or vibration when worn on the skin. This device, reported in a paper published in Science Robotics, represents a step towards creating haptic technologies that can reproduce a more varied and realistic range of touch sensations. The device consists of a soft, stretchable electrode attached to a silicone patch. It can be worn like…
How algae get nitrogen to grow. Newly discovered symbiosis between Rhizobia and diatoms could also open new avenues for agriculture. In a new study, scientists from the Max Planck Institute for Marine Microbiology, the Alfred Wegener Institute and the University of Vienna shed light on an unexpected partnership: A marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean. This symbiosis likely plays a key role for global marine…
Key Mechanism of Herpesvirus Egress Uncovered. An international team of researchers, led by the Leibniz Institute of Virology (LIV), uncovered crucial details on how herpesviruses exit the cell nucleus without compromising the integrity of the nuclear envelope. The study, published on June 25 in the renowned journal Nature Microbiology, utilized advanced electron cryo-tomography to visualize the structures involved.
