Phys.org / How topological surfaces boost clean energy catalysts
The oxygen reduction reaction (ORR) is a key process in fuel cells and metal-air batteries, technologies expected to play a central role in a low-carbon energy future. However, ORR proceeds slowly on most materials, limiting ...
Phys.org / Cracks on Europa sport traces of ammonia
The search for life-supporting worlds in the solar system includes the Jovian moon Europa. Yes, it's an iceberg of a world, but underneath its frozen exterior lies a deep, salty ocean and a nickel-iron core. It's heated by ...
Tech Xplore / A smelly snapshot of the current state of electronic noses for robots
Robots are getting better at sniffing out smells thanks to improvements in electronic noses (e-noses). A comprehensive review of the state of robot olfaction, published in the journal npj Robotics, has surveyed recent advances ...
Phys.org / Fast-growing trees are taking over the forests of the future and putting biodiversity, climate resilience under pressure
Trees play a central role in life on Earth. They store CO₂, provide habitats for animals, fungi, and insects, stabilize soils, regulate water cycles, and supply resources that humans rely on—from timber and food to recreation ...
Tech Xplore / Mechanical engineers' wood-based material could cut energy costs
University of Texas at Dallas researchers and their collaborators have developed and patented a wood-based material that can store and discharge heat to help make building temperatures more comfortable without using electricity. ...
Phys.org / Satellite study reveals 24.2 billion ton annual groundwater loss in High Mountain Asia
A recent satellite-based study has uncovered alarming declines in groundwater storage across High Mountain Asia (HMA), widely known as the "Asian Water Tower." This critical water source, which sustains agricultural irrigation, ...
Phys.org / Sprint or marathon? Aging muscle stem cells shift from rapid repair to long-term survival
Aging muscles heal more slowly after injury—a frustrating reality familiar to many older adults. A UCLA study conducted in mice reveals an unexpected cause: Stem cells in aged muscle accumulate higher levels of a protein ...
Tech Xplore / Quantum-inspired wireless technology could tackle 6G's biggest challenges
Researchers at Monash University and the University of Melbourne have developed a quantum-inspired approach to optical wireless communication that promises to make 6G networks faster, more reliable and energy-efficient. As ...
Phys.org / Lab study suggests longer waves fracture floating ice sheets at lower stress
When waves are moving across ice-covered seas, they can cause sheets of ice to bend and ultimately break. Understanding the processes underlying these wave-induced ice fractures and predicting when they will occur could help ...
Phys.org / Spider spinneret evolution: How a genome duplication event 438 million years ago set the stage
Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they are known today. Arthropods ...
Phys.org / Iguanas fall from trees in Florida as icy weather bites southern US
Iguanas stunned by cold temperatures dropped from trees in usually balmy Florida on Sunday as icy conditions blasted southern U.S. states, dumping nearly a half-meter of snow in some areas and whipping up high winds that ...
Tech Xplore / The data center surge has a hidden source of carbon emissions
Data centers siphon huge amounts of energy to power artificial intelligence. But their environmental footprint starts to balloon even before the first server switches on due to the immense amount of carbon-intensive concrete ...
