New optical tweezers can trap large and irregularly shaped particles
Researchers have developed new optical tweezers that can stably trap particles that are large—about 0.1 mm—and irregularly shaped. While conventional optical tweezers use highly focused laser beams to trap micro- or nano-scale rod shaped or spher.....»»
Compact on-chip polarimeter measures light polarization with high accuracy
Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made of bulky components, which makes them difficult to.....»»
Active particles reorganize 3D gels into denser porous structures, study shows
Colloidal gels are complex systems made up of microscopic particles dispersed in a liquid, ultimately producing a semi-solid network. These materials have unique and advantageous properties that can be tuned using external forces, which have been the.....»»
Most precise measurement of electrically neutral beauty meson lifetime achieved
The ATLAS collaboration at the Large Hadron Collider (LHC) has released a new high-precision measurement of the lifetime of the electrically neutral beauty (B0) meson—a hadron composed of a bottom antiquark and a down quark......»»
By looking at individual atoms in tooth enamel, researchers are learning what happens to our teeth as we age
Teeth are essential for helping people break down the food they eat, and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repa.....»»
New physics sim trains robots 430,000 times faster than reality
"Genesis" can compress training times from decades into hours using 3D worlds conjured from text. On Thursday, a large group of university and private industry researchers unveile.....»»
Sustainability not an important criterion in top executives" remuneration
A study by an international team of researchers from the University of Tübingen and the HEC business school in Paris has shown that the payment of bonuses to executive board members in large European corporations is only minimally influenced by whet.....»»
In-plane magnetic fields reveal new Hall effect behaviors in advanced materials
In-plane magnetic fields are responsible for inducing anomalous Hall effect in EuCd2Sb2 films, report researchers from the Institute of Science Tokyo. By studying how these fields change electronic structures, the team discovered a large in-plane ano.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
Apple collaborates with NVIDIA to research faster LLM performance
In a blog post today, Apple engineers have shared new details on a collaboration with NVIDIA to implement faster text generation performance with large language models. Apple published and open sourced its Recurrent Drafter (ReDrafter) technique.....»»
Nonlinear "skin effect" unveiled in antiferromagnetic materials
A team of researchers has identified a unique phenomenon, a "skin effect," in the nonlinear optical responses of antiferromagnetic materials. The research, published in Physical Review Letters, provides new insights into the properties of these mater.....»»
Antineutrino detection gets a boost with novel plastic scintillator
How do you find and measure nuclear particles, like antineutrinos, that travel near the speed of light?.....»»
New radar algorithm reveals hidden dance of ionospheric plasma
At night, charged particles from the sun caught by Earth's magnetosphere rain down into the atmosphere. The impacting particles rip electrons from atoms in the atmosphere, creating both beauty and chaos. These high-energy interactions cause the north.....»»
Thin-film tech makes nuclear clocks a 1,000 times less radioactive and more affordable
In the quest for ultra-precise timekeeping, scientists have turned to nuclear clocks. Unlike optical atomic clocks—which rely on electronic transitions—nuclear clocks utilize the energy transitions in the atom's nucleus, which are less affected b.....»»
Chinese detector to hunt elusive neutrinos deep underground
Underneath a granite hill in southern China, a massive detector is nearly complete that will sniff out the mysterious ghost particles lurking around us......»»
Cutting-edge satellite tracks lake water levels in Ohio River Basin
The Ohio River Basin stretches from Pennsylvania to Illinois and contains a system of reservoirs, lakes, and rivers that drains an area almost as large as France. Researchers with the SWOT (Surface Water and Ocean Topography) mission, a collaboration.....»»
This 1080p projector is on sale for a very affordable $50
The Groview 1080p Projector, which can project images as large as 300 inches, is on sale from Walmart with a huge $150 discount, bringing its price down to $50......»»
Nvidia’s new app is causing large frame rate dips in many games
Fully disabling optional, AI-powered filters seems to fix the problem. When Nvidia replaced the longstanding GeForce Experience App with a new, unified Nvidia App last month, most.....»»
Were Neanderthals cold-adapted or were they just ready for anything? Ribcage reconstruction may hold the answer
Researchers at the Department of Paleobiology, Museo Nacional de Ciencias Naturales in Madrid report that analysis of a Neanderthal ribcage from a cave in Iraq exhibits a "bell-shaped" thorax configuration typical of Neanderthals elsewhere, differing.....»»
ALMA observations investigate disk and jet of a massive protostar
Astronomers from Italy and Spain have used the Atacama Large Millimeter/submillimeter Array (ALMA) to observe a massive protostar designated IRAS 20126+4104. The observational campaign, detailed in a paper published Dec. 9 on the arXiv preprint serve.....»»
"Video game ecology" can help us understand the climate crisis in our forests
When we think of climate change we often think of extreme events like flooding rains and large bushfires. But climate change can also have slower, more subtle impacts on our landscapes......»»
