Tech Xplore / Can AI build a machine that draws a heart? What automated mechanism design could mean for mechanical engineering
Can you design a mechanism that will trace out the shape of a heart? How about the shape of a moon, or a star? Mechanism design—the art of assembling linkages and joints to create machines with prescribed motion—is one ...
Tech Xplore / Converting human urine into clean energy: Researchers optimize the process
Researchers at McGill University have improved the efficiency of a method for converting human urine into clean energy. The method employs microbial fuel cells (MFCs), which use bacteria to turn organic waste into electricity, ...
Tech Xplore / Compressorless hydrogen turbine runs 303 seconds, beating NASA's 250-second record
Researchers at Karlsruhe Institute of Technology (KIT) have set a record runtime with a new compressorless gas turbine. The burner, featuring a revolutionary pressure-gain combustion technology, operated for 303 seconds. ...
Tech Xplore / Fiber batteries promise 'smart clothing,' but two obstacles stand in the way
Fiber batteries are an emerging technology which could one day be used to create smart clothing with a wide array of functions, from charging electronic devices to acting as wearable controllers. However, a new study finds ...
Tech Xplore / Magnetic gear reconfigures the Yagi-Uda antenna for future 6G developments
As researchers around the world race toward the realization of 6G wireless communication systems, the need for antennas that can dynamically adapt to ever-changing signal environments has never been greater. A key requirement ...
Tech Xplore / How AI can cause businesses to lose their knowledge
Over time, the loss of human expertise caused by AI use can impair the quality of that very AI—in the worst case, insidiously and unnoticed. This is the finding of a new study by researchers from the University of Passau ...
Tech Xplore / AI 'arms race' risks human extinction, warns top computing expert
Tech CEOs are locked in an artificial intelligence "arms race" that risks wiping out humanity, top computer science researcher Stuart Russell told AFP on Tuesday, calling for governments to pull the brakes.
Tech Xplore / AI model reads social media language to flag mental health risks
Mental health problems are among the most pressing of public health challenges, affecting millions across different age groups and societies. Depression, anxiety, and stress-related conditions rank among the leading causes ...
Tech Xplore / Woven nickel-titanium structures unlock new flexibility in 3D-printed shape-memory materials
At first glance, few materials would seem to have less in common than metals and textiles. And yet, by manufacturing nickel-titanium alloys as a highly deformable, interwoven material, more similar to fabric than a typical ...
Tech Xplore / Why 'zero-knowledge encryption' may not stop password theft if servers are hacked
People who regularly use online services have between 100 and 200 passwords. Very few can remember every single one. Password managers are therefore extremely helpful, allowing users to access all their passwords with just ...
Tech Xplore / Organic solar cells degrade quickly, but a solid additive could help them last longer
Solar power continues to grow—accounting for most new capacity added to U.S. electric grids in 2024—but the mid-1950s technology most often used to capture the sun's energy comes with environmental costs.
Tech Xplore / Miniaturized radar chip developed for next-generation wireless networks
A miniaturized radar chip, developed by researchers at Science Tokyo, advances Integrated Sensing and Communication for Beyond 5G and 6G systems. Measuring just 0.24 mm2 and consuming only 9.8 mW, the compact, low-power device ...
