Superradiant atoms can help us measure time more precisely than ever. In a new study, researchers from the University of Copenhagen present a new method for measuring the time interval, the second, mitigating some of the limitations that today’s most advanced atomic clocks encounter. The result could have broad implications in areas such as space travel, volcanic eruptions and GPS systems. The second is the most precisely-defined unit of measurement, compared to other base units such as the kilogram, meter,…
The electrode sheet of the thermoelectric device consists of ionic hydrogel, which is sandwiched between the electrodes to form, and the Prussian blue on the electrode undergoes a redox reaction to improve the energy density and power density of the ionic thermoelectric generator. Prof. Zeng Wei of the Institute of Chemical Engineering, Guangdong Academy of Sciences, said that at the beginning, the group mainly carried out research based on the thermal diffusion effect and published a series of research results….
New publication reports record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device. In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy’s unique approach, known as a sheared-flow-stabilized Z pinch, has now joined those rarefied ranks, far exceeding this plasma temperature milestone in a…
Researchers at UC San Diego have deployed state-of-the art imaging techniques to discover the metabolism driving Alzheimer’s disease; results suggest new treatment strategies. Alzheimer’s disease causes significant problems with memory, thinking and behavior and is the most common form of dementia, affecting more than 50 million people around the world each year. This number is expected to triple by the year 2050. Using their own state-of-the art imaging technologies, scientists at the University of California San Diego have now revealed…
After stroke and heart attack: Every year, between 250,000 and 300,000 people in Germany suffer from a stroke or heart attack. These patients suffer immune disturbances and are very frequently susceptible to life-threatening bacterial infections. Until now, little was known about the underlying mechanisms of this immune dysfunction. Research teams from the Faculty of Medicine at the University Hospital of the University of Duisburg-Essen and the Leibniz Institute for Analytical Sciences in Dortmund have now uncovered a previously unknown cause…
Researchers at Helmholtz Munich and the LMU University Hospital Munich introduce DELiVR, offering a new AI-based approach to the complex task of brain cell mapping. The deep learning tool democratizes advanced neuroscience by eliminating the need for coding expertise. DELiVR empowers biologists to investigate disease-related spatial cell dynamics efficiently, fostering the development of precision therapies for enhanced patient care. Democratizing 3D Brain Analysis Many diseases are linked with changes in the expression of certain proteins in the brain. To study…
WSL Institute for Snow and Avalanche Research (SLF) researchers expect an elevated wildfire danger in the Alpine Foreland from 2040 onwards due to changing meteorological conditions. The danger currently remains very low in that region, but there is likely to be a shift in this regard as a result of climate change. There is likely to be a significant increase in the danger of wildfires through the 21st century. Indeed, the expectation is that by 2100 the danger will be…
In the production of printed circuit boards (PCBs), micrometer-diameter vias – known as microvias – are drilled through multilayer PCBs. Lasers can drill through these structures with high throughput and micrometer precision. A measurement technique based on laser-induced breakdown spectroscopy (LIBS) is set to check the quality of the holes inline and control the process. Because of the high density of circuits and components, modern printed circuit boards are extremely challenging to manufacture. Lasers are used to drill the interconnects…
Using light pulses as a model for electrical defibrillation, Göttingen scientists developed a method to assess and modulate the heart function. The research team from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) and the University Göttingen Medical Center thus paved the way for an efficient and direct treatment for cardiac arrhythmias. This may be an alternative for the strong and painful electrical shocks currently used. Cardiac arrhythmias account for around 15-20% of annual deaths worldwide. In case of…
… for ultra-light and compact augmented reality systems. As part of the HOT project (High-performance transparent and flexible microelectronics for photonic and optical applications), scientists from the Fraunhofer Institute for Photonic Microsystems IPMS have developed a semi-transparent microdisplay. This microdisplay is significantly lighter than conventional combiner-based optical see-through near-to-eye systems and offers high resolution. The microdisplay will be presented at the SID Display Week 2024 in San Jose, USA, at the German Pavilion, booth number 1124. In today’s time, more…
Nebraska researcher Eric Markvicka gets NSF CAREER Award to pursue manufacture of novel materials for soft robotics and stretchable electronics. Engineers are increasingly eager to develop robots that mimic the behavior of animals and biological organisms, whose adaptability, resilience and efficiency have been refined over millions of years of evolution. In bringing bio-inspired robots to life, scientists must first create soft matter counterparts that match the softness and functionality of biological tissue. University of Nebraska–Lincoln engineer Eric Markvicka is at the forefront of…
Scientists are closer to finding out how. Pyrrolizidine alkaloids are as bitter and toxic as they are hard to pronounce. They’re produced by several different types of plants and are among the leading causes of accidental death in cattle. Plants that contain these alkaloids have made it very clear they don’t want to be consumed, but that hasn’t deterred bella moths (Utetheisa ornatrix). These day-flying moths exclusively eat the alkaloid-laden leaves and seeds of rattlebox plants. They then use the…
…for enhanced microscopy analysis. Observing individual cells through microscopes can reveal a range of important cell biological phenomena that frequently play a role in human diseases, but the process of distinguishing single cells from each other and their background is extremely time consuming — and a task that is well-suited for AI assistance. AI models learn how to carry out such tasks by using a set of data that are annotated by humans, but the process of distinguishing cells from…
FAU chemists conduct research into novel approach of using an organic module for storing solar energy. Until now, the generation and storage of electricity from solar energy has been dependent on various devices, leading to conversion losses. That may change soon: chemists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and other research institutes in Germany, Australia, the United Kingdom, Italy, Sweden and the USA are conducting research into a hydrocarbon molecule that can either convert sunlight into electricity or save the energy for…
Useful for thrombectomy data transfer. In an ischaemic stroke, an artery in the brain is blocked by blood clots and the brain cells can no longer be supplied with blood as a result. Doctors must therefore act quickly and unblock the artery with the help of catheters. During the so-called mechanical thrombectomy, a lot of data has to be recorded and then transferred to various registers. Dr Nils Lehnen, senior physician at the Clinic for Diagnostic and Interventional Neuroradiology and…
Scientists at the NMI have unraveled the mode of action of collagen crosslinking in the treatment of corneal defects and the results open up new opportunities for the use of collagen in medicine. Collagen has been used in ophthalmology since the 1990s, particularly in the treatment of corneal defects. However, why and how this technique works was only known in theory. Researchers at the NMI Natural and Medical Sciences Institute in Reutlingen led by Lu Fan have found the necessary…
