KIMM develops technology for detecting injection of medication to prevent medical accidents related to analgesic drug infusion pump in hospitals. KIMM develops technology for a sensor to measure low flow rate and bubbles during drug infusion. Mass production of the world’s first safe electric drug infusion pump equipped with a flow sensor is in progress. Excessive administration of analgesic drugs frequently results in medical accidents. To prevent the occurrence of these accidents, a drug infusion pump featuring a technology for…
Our built environment is aging and failing faster than we can maintain it. Recent building collapses and structural failures of roads and bridges are indicators of a problem that’s likely to get worse, according to experts, because it’s just not possible to inspect every crack, creak and crumble to parse dangerous signs of failure from normal wear and tear. In hopes of playing catch-up, researchers in Drexel University’s College of Engineering are trying to give robotic assistants the tools to…
A new way of creating color uses the scattering of light of specific wavelengths around tiny, almost perfectly round silicon crystals. This Kobe University development enables non-fading structural colors that do not depend on the viewing angle and can be printed. The material has a low environmental and biological impact and can be applied extremely thinly, promising significant weight improvements over conventional paints. An object has color when light of a specific wavelength is reflected. With traditional pigments, this happens…
Scripps Research team restored neuron-to-neuron connections in human cells. Nerve cells in the brain demand an enormous amount of energy to survive and maintain their connections for communicating with other nerve cells. In Alzheimer’s disease, the ability to make energy is compromised, and the connections between nerve cells (called synapses) eventually come apart and wither, causing new memories to fade and fail. A Scripps Research team, reporting in the journal Advanced Science on January 18, 2024, has now identified the…
Poison ivy ranks among the most medically problematic plants. Up to 50 million people worldwide suffer annually from rashes caused by contact with the plant, a climbing, woody vine native to the United States, Canada, Mexico, Bermuda, the Western Bahamas and several areas in Asia. It’s found on farms, in woods, landscapes, fields, hiking trails and other open spaces. So, if you go to those places, you’re susceptible to irritation caused by poison ivy, which can lead to reactions that…
Prototypes within Two Years. Significantly higher storage capacity, safer operation and durability: this is what industry and research expect from future solid-state batteries compared to conventional lithium-ion batteries. A consortium involving the University of Duisburg-Essen is aiming to realize prototypes up to pilot scale. The decisive anode material was developed at the University’s Institute for Energy and Materials Processes. The Federal Ministry of Education and Research is funding the project* for two years with 1.7 million euros. The structure of…
Sensors that monitor infrastructure, such as bridges or buildings, or are used in medical devices, such as prostheses for the deaf, require a constant supply of power. The energy for this usually comes from batteries, which are replaced as soon as they are empty. This creates a huge waste problem. An EU study forecasts that in 2025, 78 million batteries will end up in the rubbish every day. A new type of mechanical sensor, developed by researchers led by Marc…
Artificial intelligence using neural networks performs calculations digitally with the help of microelectronic chips. Physicists at Leipzig University have now created a type of neural network that works not with electricity but with so-called active colloidal particles. In their publication in the prestigious journal “Nature Communications”, the researchers describe how these microparticles can be used as a physical system for artificial intelligence and the prediction of time series. “Our neural network belongs to the field of physical reservoir computing, which…
High-speed experiments will help identify lightweight, protective “metamaterials” for spacecraft, vehicles, helmets, or other objects. An intricate, honeycomb-like structure of struts and beams could withstand a supersonic impact better than a solid slab of the same material. What’s more, the specific structure matters, with some being more resilient to impacts than others. That’s what MIT engineers are finding in experiments with microscopic metamaterials — materials that are intentionally printed, assembled, or otherwise engineered with microscopic architectures that give the overall…
A theoretical framework for measuring the Reynolds similitude in superfluids could help demonstrate the existence of quantum viscosity. Every fluid — from Earth’s atmosphere to blood pumping through the human body — has viscosity, a quantifiable characteristic describing how the fluid will deform when it encounters some other matter. If the viscosity is higher, the fluid flows calmly, a state known as laminar. If the viscosity decreases, the fluid undergoes the transition from laminar to turbulent flow. The degree of…
Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers. The research team, from the University of Cambridge, used machine learning algorithms to teach a robotic sensor to quickly slide over lines of braille text. The robot was able to read the braille at 315 words per minute at close to 90% accuracy. Although the robot braille reader was not developed as an assistive technology, the researchers…
It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes. Only NASA’s James Webb Space Telescope can deliver highly detailed scenes of nearby galaxies in a combination of near- and mid-infrared light – and a set of these images was publicly released today. These Webb images are part of a large, long-standing project, the…
… essential to monitor climate change. We know that our climate is changing. Extreme weather events are becoming more common, sea levels are rising and overall, our planet is getting warmer. Monitoring these changes is critical. One of the best indicators of climate change is the Ocean Heat Content (OHC) estimate, a measurement of overall oceanic temperature calculated by gathering water temperature data in oceans around the world in differing locations, at varying depths and across time. The data necessary…
… in extreme fields with the heaviest two-electron ion. Recently, an international research team has successfully carried out a high precision x-ray spectroscopy measurement on helium-like uranium, the simplest and heaviest many-electron atomic system. The obtained results allow, for the first time in this regime, to disentangle and to test separately high-order (two-loop) one-electron and two-electron quantum electrodynamics (QED) effects and set a new important benchmark for QED in the strong field domain. Moreover, the achieved accuracy of 37 parts…
“Artificial molecular motors are molecules that absorb light from an external source, such as sunlight, and convert the energy in light into kinetic energy,” says Bo Durbeej, professor at Linköping University (LiU), who led the study published in Chemistry – a European Journal. “Molecular motors” may sound like science fiction, but in the body there are many biological molecular motors that drive muscles and transport substances inside cells. Chemistry and nanotechnology researchers have long been aiming to develop artificial molecular…
Study validates method for guided discovery of 3D flat-band materials. Rice University scientists have discovered a first-of-its-kind material, a 3D crystalline metal in which quantum correlations and the geometry of the crystal structure combine to frustrate the movement of electrons and lock them in place. The find is detailed in a study published in Nature Physics. The paper also describes the theoretical design principle and experimental methodology that guided the research team to the material. One part copper, two parts vanadium…
