Hardware processing for AI goes 3D, boosting processing power. A breakthrough development in photonic-electronic hardware could significantly boost processing power for AI and machine learning applications. The approach uses multiple radio frequencies to encode data, enabling multiple calculations to be carried out in parallel. The method shows promise for outperforming state-of-the-art electronic processors, with further enhancements possible. In a paper published today in Nature Photonics, researchers from the University of Oxford, along with collaborators from the Universities of Muenster, Heidelberg,…
This machine developed at the University of Bonn measures just one ten-thousandth of a millimeter. An international team of scientists headed by the University of Bonn has developed a novel type of nanomotor. It is driven by a clever mechanism and can perform pulsing movements. The researchers are now planning to fit it with a coupling and install it as a drive in complex machines. Their findings have now appeared in the journal Nature Nanotechnology. This novel type of motor is…
A University of Oklahoma-led article published in Geophysical Research Letters highlights newly measured extremes recorded during the National Aeronautics and Space Administration Dynamics and Chemistry of the Summer Stratosphere field project. “Extreme Altitudes of Stratospheric Hydration by Midlatitude Convection Observed During the DCOTSS Field Campaign,” led by OU School of Meteorology Interim Director and Associate Professor Cameron Homeyer, summarizes the extremes in measured stratospheric depth of hydration by convection recorded during the DCOTSS project as a whole, and then highlights a specific…
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This ‘fast radio burst’ (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory’s (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took eight billion years to reach us. The FRB is also one of the most energetic ever observed; in a tiny fraction of a second it released the…
Model is small, durable and contains all functions in one capsule. When the heart beats too slowly, the use of a pacemaker may be necessary. The device works like a pacemaker, restoring the heartbeat to a normal rhythm. The Department of Cardiology and Angiology at Hannover Medical School (MHH) is one of the first hospitals in Germany to offer implantation of the new innovative AVEIR VR pacemaker. The model is associated with many advantages: It has no electrodes, it can…
Successful trial installation in Erlangen… The fully automated measurement of the biophysical properties of hundreds of cell samples in just a few days is the goal of the cooperative project “AutoRAPID,” involving scientists from the Max Planck Institute for the Science of Light (MPL) in Erlangen and the Fraunhofer Institute for Production Technology and Automation IPA in Mannheim. For the first time, the biophysicists and automation engineers have assembled their individual components in a setup in Erlangen. Researchers from the…
FAU team of researchers succeed for the first time in accelerating electrons using a nano device. Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky. Until now, no substantial…
Researchers in Sweden have developed a microscale device for implantation in the eye, which presents new opportunities for cell-based treatment of diabetes and other diseases. Aiming towards encapsulating insulin-producing pancreatic cells and electronic sensors, the 3D-printed device was developed by a team from KTH Royal Institute of Technology and Karolinska Institutet. The researchers reported the results of the work in the journal Advanced Materials. The collaboration between KTH and Karolinska Institutet enables micro-organs—namely pancreatic islets or islets of Langerhans—to be positioned…
Researchers have invented an experimental wearable device that generates power from a user’s bending finger and can create and store memories, in a promising step towards health monitoring and other technologies. The innovation features a single nanomaterial incorporated into a stretchable casing fitted to a person’s finger. The nanomaterial enabled the device to generate power with the user bending their finger. The super-thin material also allows the device to perform memory tasks, as outlined below. Multifunctional devices normally require several…
In an extensive investigation, EMBL researchers have tested over 10,000 drug combinations against some of the leading pathogenic bacteria carrying antimicrobial resistance and causing mortality. Antimicrobial resistance – occurring when pathogens can survive antibiotic treatment – is one of the most rapidly emerging global public health threats today. According to a 2022 study, nearly five million deaths were associated with antibiotic-resistant bacteria in 2019, with over a million deaths per year directly attributable to antimicrobial resistance. In a new study, researchers…
The U.S. National Science Foundation (NSF) is looking for materials that “revolutionize and engineer our future.” Researchers at Iowa State University and the University of California, Santa Barbara think they can do just that by fundamentally changing Digital Light Processing – a type of 3D printing that users light rather than heat to quickly cure and harden liquid resin into plastic layers – to enable multi-material printing. “We want to produce two material properties with the same resin,” said Adarsh…
… helps mice recover after stroke. New research offers a tantalizing avenue for treating stroke by reprogramming microglia, the main immune cells in the brain, to replace damaged neurons. Researchers at Kyushu University have discovered that turning brain immune cells into neurons successfully restores brain function after stroke-like injury in mice. These findings, published on October 10 in PNAS, suggest that replenishing neurons from immune cells could be a promising avenue for treating stroke in humans. Stroke, and other cerebrovascular…
Robotic prosthetic ankles that are controlled by nerve impulses allow amputees to move more “naturally,” improving their stability, according to a new study from North Carolina State University and the University of North Carolina at Chapel Hill. “This work focused on ‘postural control,’ which is surprisingly complicated,” says Helen Huang, corresponding author of the study and the Jackson Family Distinguished Professor in the Joint Department of Biomedical Engineering at NC State and UNC. “Basically, when we are standing still, our…
An advanced new three-dimensional (3D) computer simulation of the light emitted following a merger of two neutron stars has produced a similar sequence of spectroscopic features to an observed kilonova. “The unprecedented agreement between our simulations and the observation of kilonova AT2017gfo indicates that we understand broadly what has taken place in the explosion and aftermath,” says Luke Shingles, scientist at GSI/FAIR and the leading author of the publication in “The Astrophysical Journal Letters”. Recent observations that combine both gravitational…
A team from the Vehicle Safety Institute at TU Graz has used Human Body Models to investigate accidents involving electric scooters and identified the most important factors for preventing serious injuries. The use of e-scooters has increased significantly in recent years, but so has the number of accidents involving this relatively new form of transport. At the same time, knowledge about injury mechanisms in this area was still very limited. In the project SURF, funded by Zukunftsfonds Steiermark, the Vehicle…
A newly discovered type of electronic behavior could help with packing more data into magnetic memory devices. Ordinary pencil lead holds extraordinary properties when shaved down to layers as thin as an atom. A single, atom-thin sheet of graphite, known as graphene, is just a tiny fraction of the width of a human hair. Under a microscope, the material resembles a chicken-wire of carbon atoms linked in a hexagonal lattice. Despite its waif-like proportions, scientists have found over the years…
