Event provides new evidence that traveling stars can form binary systems. From a zoomed out, distant view, star-forming cloud L483 appears normal. But when a Northwestern University-led team of astrophysicists zoomed in closer and closer, things became weirder and weirder. As the researchers peered closer into the cloud, they noticed that its magnetic field was curiously twisted. And then — as they examined a newborn star within the cloud — they spotted a hidden star, tucked behind it. “It’s the…
… using AI-enabled surgical robot. A novel AI-empowered robotic device successfully underwent clinical trial for assisting in percutaneous nephrolithotomy— surgery for removing kidney stones. Percutaneous nephrolithotomy (PCNL) is an efficient, minimally-invasive, gold standard procedure used for removing large kidney stones. Creating an access from the skin on the back to the kidney—called renal access, is a crucial yet challenging step in PCNL. An inefficiently created renal access can lead to severe complications including massive bleeding, thoracis and bowel injuries, renal…
Collaborative research published in Nature Electronics shows promise of probabilistic computers. The rise of artificial intelligence (AI) and machine learning (ML) has created a crisis in computing and a significant need for more hardware that is both energy-efficient and scalable. A key step in both AI and ML is making decisions based on incomplete data, the best approach for which is to output a probability for each possible answer. Current classical computers are not able to do that in an…
Watch this. Watch for the patterns created as the circles move across each other. Those patterns, created by two sets of lines offset from each other, are called moiré (pronounced mwar-AY) effects. As optical illusions, moiré patterns create neat simulations of movement. But at the atomic scale, when one sheet of atoms arranged in a lattice is slightly offset from another sheet, these moiré patterns can create some exciting and important physics with interesting and unusual electronic properties. Mathematicians at…
Researchers discover and characterize a novel membraneless organelle that could play a role in Alzheimer’s treatment. Researchers in UC Santa Barbara neuroscientist Kenneth S. Kosik’s lab have discovered a novel organelle — a previously unknown cell structure whose function it is to help clean up faulty proteins in times of stress and keep cells functioning in top condition. Optimizing this membraneless organelle, which they call a BAG2 condensate, could lead to treatments for conditions that are the result of misfolded proteins, including…
Scientists from the Institute of Industrial Science at The University of Tokyo fabricated three-dimensional vertically formed field-effect transistors to produce high-density data storage devices by ferroelectric gate insulator and atomic-layer-deposited oxide semiconductor channel. Furthermore, by using antiferroelectric instead of ferroelectric, they found that only a tiny net charge was required to erase data, which leads to more efficient write operations. This work may allow for new even smaller and more eco-friendly data-storage memory. While consumer flash drives already boast huge…
Identical light particles (photons) are important for many technologies that are based on quantum physics. A team of researchers from Basel and Bochum has now produced identical photons with different quantum dots – an important step towards applications such as tap-proof communications and the quantum internet. Many technologies that make use of quantum effects are based on exactly equal photons. Producing such photons, however, is extremely difficult. Not only do they need to have precisely the same wavelength (colour), but…
ITA Institut für Textiltechnik of RWTH Aachen University will once again be showcasing its entire research spectrum at the Elmatex joint stand in Hall 12.0 B55 at Techtextil 2022 https://techtextil.messefrankfurt.com/frankfurt/en.html in Frankfurt am Main, Germany: 1. 3D printing robot on textiles – experience it live in Hall 12.0 B55! The 3D printing robot is a mobile and size-independent 3D printer for large-area components on textiles. For the first time, a 2.5D support structure can be printed on a textile with…
Southern Africa has a rich bounty of crop varieties, crop wild relatives, orphan crops and underutilised plant species, collectively known as plant genetic resources for food and agriculture (PGRFA), which have sustained generations of local farmers and rural communities and enabled them to cope with changing environmental conditions. The project “Farmer Resilience and Melon Crop Diversity in southern Africa” (FRAMe) aims at a future-oriented agriculture of crop diversity using melons as an example. The German Federal Ministry of Education and…
HIRI scientists show that target RNA levels influence defense against invaders. Friend or foe? Immune systems constantly face this question. They must recognize and clear foreign invaders without eliciting autoimmunity. Prokaryotic CRISPR-Cas systems recognize invaders based on genetic sequence. But what happens if the host genome shares the same sequences? A research team of the Helmholtz Institute in Würzburg in cooperation with the North Carolina State University (USA) has now discovered a control mechanism exhibited by CRISPR-Cas systems that use…
Have you ever noticed when moving furniture that heavy objects are easier to move if you rotate them at the same time as you push? Many people intuitively do this right. An international research team from Konstanz (Germany), Trieste and Milan (Italy) has now investigated this phenomenon – the reduction in static friction caused by simultaneous rotation – on the microscopic scale. In their recent study in Physical Review X, the researchers found that the reduction in static friction of…
OHIO researchers start by finding new carbon solid. As the world’s appetite for carbon-based materials like graphite increases, Ohio University researchers presented evidence this week for a new carbon solid they named “amorphous graphite.” Physicist David Drabold and engineer Jason Trembly started with the question, “Can we make graphite from coal?” “Graphite is an important carbon material with many uses. A burgeoning application for graphite is for battery anodes in lithium-ion batteries, and it is crucial for the electric vehicle…
While the national census is only just beginning in Germany, the first evaluation of our galactic neighborhood as part of the ongoing census has now been completed with the assistance of researchers at TU Dresden. The data acquired for this survey as part of the European Space Agency’s Gaia mission will be released to the public during a celebratory event on June 13, 2022, at 12:00°pm CEST. Since 2014, the Gaia satellite has been surveying the galaxies at a distance…
A new study shows the inner core oscillates. USC Dornsife scientists identify a six-year cycle of super- and sub-rotation that affected the length of a day based on their analysis of seismic data. USC scientists have found evidence that the Earth’s inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate than the planet’s surface. Their study, published today in Science Advances, shows that the inner core changed direction in the six-year period from…
Eternal matter waves. Imagining our everyday life without lasers is difficult. We use lasers in printers, CD players, pointers, measuring devices, and so on. What makes lasers so special is that they use coherent waves of light: all the light inside a laser vibrates completely in sync. Meanwhile, quantum mechanics tells us that particles like atoms should also be thought of as waves. As a result, we can build ‘atom lasers’ containing coherent waves of matter. But can we make…
Researchers created perovskite quantum dot microarrays to achieve better results in full-color light-emitting devices and expand potential applications. Quantum dots color conversion (QDCC) has become a foundational technology in the design of full-color light-emitting devices with dramatically improved color performance. However, conventional QDCC pixels fabricated by inkjet printing, that is commonly used, are still too thin to achieve efficient color conversion. A research team has developed perovskite quantum dots microarrays with strong potential for QDCC applications, including photonics integration, micro-LEDs,…
