Tech Xplore / Electric vehicles could travel farther on a single charge thanks to lithium-sulfur batteries with added platinum
More electric vehicles are on the road than ever before. But a recent global survey has found that some EV owners—about 46% in the U.S.—have considered switching back to a gasoline car. The top reason: charging. While ...
Tech Xplore / AI chatbots struggle with empathy: Overempathizing and gender bias uncovered
You can talk to an AI chatbot about pretty much anything, from help with daily tasks to the problems you may need to solve. Its answers reflect the human data that taught it how to act like a person; but how human-like are ...
Tech Xplore / Nanoscale tweaks help alloy withstand high-speed impacts
A Cornell-led collaboration devised a new method for designing metals and alloys that can withstand extreme impacts: introducing nanometer-scale speed bumps that suppress a fundamental transition that controls how metallic ...
Tech Xplore / Feeling is believing: Bionic hand 'knows' what it's touching, grasps like a human
Johns Hopkins University engineers have developed a pioneering prosthetic hand that can grip plush toys, water bottles, and other everyday objects like a human, carefully conforming and adjusting its grasp to avoid damaging ...
Tech Xplore / Open-source software that models soft materials expands engineering solutions
When mechanical and structural engineers design machines, bridges, and buildings, they calculate loads, stresses, and deformation of metal, steel, concrete, glass, wood, and plastic to find the optimal geometry that bears ...
Tech Xplore / Combating deepfakes with CAPTCHA-like verification that uses real-time physical interactions
Researchers at the Carnegie Mellon University Robotics Institute and the Massachusetts Institute of Technology (MIT), created CHARCHA ( Computer Human Assessment for Recreating Characters with Human Actions), a secure and ...
Tech Xplore / Turning liquor waste into power: Baijiu sediment transformed into anode for sodium-ion batteries
A small team of materials engineers at the University of Electronic Science and Technology of China, working with Wuliangye, a manufacturer of baijiu, has developed a carbon-source anode using baijiu sediment for use in a ...
Tech Xplore / Why more water is not always better in ion-conducting membranes: New insights for clean energy technology
Researchers at the University of Chicago Pritzker School of Molecular Engineering (UChicago PME) and at the Tandon School of Engineering of New York University have made a breakthrough in understanding how water transports ...
Tech Xplore / Sony's aibo dog could soon walk quietly and perform elaborate dance routines
Aibo, the cute-looking robot puppy developed by Sony, was designed to be a household companion. The robot can already emulate many of the movements and behaviors of real dogs, such as walking on four legs, responding when ...
Tech Xplore / Scientists study the hidden cost of Netflix's autoplay
Autoplay, a feature that automatically begins the next episode or movie without user input, has become a staple of modern streaming platforms like Netflix. But how much is this convenience truly costing us in terms of control ...
Tech Xplore / Chain of Draft approach allows AI models to carry out tasks using far fewer resources
A small team of AI engineers at Zoom Communications has developed a new approach to training AI systems that uses far fewer resources than the standard approach now in use. The team has published their results on the arXiv ...
Tech Xplore / Aqueous organic flow batteries: Pyrene tetraone derivative offers stable, high-density energy storage
Aqueous organic flow batteries (AOFBs) hold promise for renewable energy integration and electricity grid storage due to their inherent safety, as well as the availability of naturally abundant and synthetically tunable organic ...
