Tech Xplore / New AI method uses engineering knowledge to estimate disaster damage from incomplete satellite imagery
A new technology has been developed that can rapidly predict city-scale structural damage even when portions of satellite imagery are obscured by clouds or smoke immediately after a disaster.
Tech Xplore / New method reveals how efficiently water-based cells turn waste heat into electricity
Most electricity is generated by using heat to produce steam, which then turns a turbine. Although this approach performs exceptionally well in the high-temperature, superheated-steam regime, we currently lack widely applicable ...
Tech Xplore / Ultrathin mesh harvests energy from human heart cells to generate electricity
A team of engineers led by the University of Massachusetts Amherst has designed an ultrathin, flexible mesh that seamlessly integrates electronics with human cells to provide a continuous, reliable, powerful electrical supply. ...
Tech Xplore / 'SANDO' system ensures a robot's flight path will remain collision-free in uncharted territory
Uncrewed aerial vehicles (UAVs) could fly deep into the heart of a raging wildfire, avoiding sudden flare-ups and dodging falling tree branches to gather critical information for rescuers. But in this dangerous situation, ...
Tech Xplore / Green hydrogen production method yields valuable industrial chemical instead of oxygen
A study published in the journal Nature Communications presents an advance in hydrogen production: a green, cost-effective process that generates hydrogen while simultaneously producing valuable chemicals for industry. The ...
Tech Xplore / Atomically thin transistors could transform computing by surpassing silicon's switching limit
For decades, silicon transistors have driven computational power, and scientists have devoted much of their time to making them smaller. That is because shrinking these tiny electronic switches that make up computer chips ...
Tech Xplore / How to head into VR without wearing a headset
A person wearing bulky goggles, turning awkwardly in circles and reaching out to grab something that isn't there—that is the image many of us have of virtual reality, and one that researchers at Kyushu University want to ...
Tech Xplore / Agentic AI turns simple language into self-guided X-ray scans of microelectronics
Science has increasingly used artificial intelligence (AI) as a kind of microscope—sorting data, analyzing images and revealing hidden patterns. Now a new shift is underway: AI that not only breaks down data but also helps ...
Tech Xplore / Out-of-sync sleep schedules may steer people toward AI for dating and job assessments
Life often gets in the way of going to bed in sync with our circadian rhythm and getting enough sleep. Work, school and other social commitments can pull our schedules out of step, and scientists call this mismatch social ...
Tech Xplore / Wave-shaped wall and roof designs can protect against hurricane-force winds
Florida State University faculty are helping build stronger structures by examining how wave-shaped patterns on exterior walls and roofs reduce wind loads on low-rise buildings by up to 60%.
Tech Xplore / Solar cells gain efficiency by emitting light in fewer directions
Solar cells absorb sunlight and convert it into electricity. This process, however, is not perfect, and a large part of the solar energy is simply lost along the way. Some of it is lost as heat, while photons with insufficient ...
Tech Xplore / Laser-sculpted bumps that guide light around obstacles could make fiber-optic communications faster and more reliable
University of Maryland (UMD) assistant professor Avik Dutt and research colleagues have demonstrated a new way to control light precisely by using microscopic structures created on the surface of hair-thin glass fibers.
