Tech Xplore / A low-tech solution to the 6G problem—metacrystal panels offer cheap way to guide wireless signals around corners
Basements, tunnels, large buildings—a weak Wi-Fi or mobile signal in these hard-to-reach places is frustrating. The usual solution is to add more electronics like routers, repeaters and base stations. Yet, as we move towards ...
Tech Xplore / Multinex: An ultra lightweight AI model advancing low light image enhancement
A University of Manchester student has developed a powerful new ultra-lightweight tool that can turn dark, noisy footage into clear, detailed and usable images. Multinex, a new model for low-light image enhancement (LLIE), ...
Tech Xplore / Human–AI jam session shapes live music with swarm intelligence
Have you ever seen birds flying across the sky in shifting, mesmerizing patterns? Or ants using their own bodies to form a living bridge that other ants can walk across?
Tech Xplore / Plastic waste yields jet fuel through new process costing as little as $1 per kilogram
Aviation is one of the sectors that contributes most to greenhouse gas emissions and climate change on Earth. One proposed strategy for mitigating or counterbalancing the effects of these emissions is to substitute existing ...
Phys.org / What happens to a star that captures a primordial black hole?
We don't know whether theorized primordial black holes (PBH) are real. If they are, they formed in the very early universe, when physics was much different. They had no stellar progenitors and were created by the direct collapse ...
Phys.org / Mining companies may soon bypass UN rules and mine the deep sea
A Canadian deep-sea mining company may become the first to commercially mine the international seabed under a controversial U.S. executive order that bypasses United Nations regulations. A recent legal analysis suggests that ...
Phys.org / Protected bike lanes, not painted lanes, lift NYC bikeshare ridership, analysis shows
Protected bike lanes increase Citi Bike ridership in New York City, but painted bike lanes and sharrows do not show a statistically significant causal effect on ridership after accounting for confounding factors, according ...
Medical Xpress / Testing AI against public health's existing tools shows mixed results
A new Penn-led randomized controlled trial has found that AI-powered chatbots can make vaccine-hesitant parents more likely to say they will immunize their children against human papillomavirus (HPV), but no more than standard ...
Phys.org / MUSE maps spiral galaxy W2246f, uncovering old core and ongoing star formation across disk
Astronomers have employed the Multi-Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT) to perform deep spectroscopic observations of a peculiar spiral galaxy known as W2246f. Results of the observational ...
Phys.org / Gold nanoparticles unlock vibrant structural colors across the visible spectrum
Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues ...
Phys.org / Cutting a photon in two creates an infinite swarm of particles
By definition, elementary particles can't be broken into smaller pieces. But in a new theoretical study published in Physical Review Letters, Johannes Skaar and colleagues have revealed what would happen if you tried anyway ...
Phys.org / Expedition to Antarctica advances research on potential melanoma treatment
Deep beneath the icy waters surrounding Antarctica, a small marine organism may hold clues to a future cancer treatment. Researchers from USF recently returned from a six-week expedition in one of the most remote environments ...
