Phys.org / Shining a light on sustainable sulfur-rich polymers that stay recyclable
For the first time, scientists have used ultraviolet (UV) light, a low-cost and readily available energy source, to successfully synthesize more sustainable and recyclable polymer materials. Led by green chemistry experts ...
Tech Xplore / Brain-inspired hardware uses single-spike coding to run AI more efficiently
The use of artificial intelligence (AI) systems, such as the models underpinning the functioning of ChatGPT and various other online platforms, has grown exponentially over the past few years. Current hardware and electronic ...
Tech Xplore / Snapchat blocks 415,000 underage accounts in Australia
Snapchat has blocked 415,000 accounts under Australia's social media ban for under-16s, the company said Monday, but warned some youngsters may be bypassing age verification technology.
Tech Xplore / Study solves key micro-LED challenges, enabling 'reality-like' visuals for AR/VR devices
From TVs and smartwatches to rapidly emerging VR and AR devices, micro-LEDs are a next-generation display technology in which each LED—smaller than the thickness of a human hair—emits light on its own. Among the three ...
Phys.org / Scientists just mapped the family tree of all 11,000 bird species—and you can explore it
The Cornell Lab of Ornithology today announced the release of a new online tool for studying biodiversity and the evolutionary relationships among birds: the illustrated Birds of the World Phylogeny Explorer. Available on ...
Phys.org / Global population living with extreme heat expected to double by 2050
A new University of Oxford study finds that almost half of the global population (3.79 billion) will be living with extreme heat by 2050 if the world reaches 2.0°C of global warming above pre-industrial levels—a scenario ...
Phys.org / NASA's Juno measures thickness of Europa's ice shell
Data from NASA's Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter's moon Europa. Using the spacecraft's Microwave Radiometer (MWR), mission scientists determined ...
Phys.org / How brick-building bacteria react to toxic chemical in Martian soil
Bacteria that thrive on Earth may not make it in the alien lands of Mars. A potential deterrent is perchlorate, a toxic chlorine-containing chemical discovered in Martian soil during various space missions.
Tech Xplore / Unsinkable metal tubes could lead to resilient ships, floating platforms and renewable energy innovations
More than a century after the Titanic sank, engineers still have hopes of someday creating "unsinkable" ships. In a step toward reaching that lofty goal, researchers at the University of Rochester's Institute of Optics have ...
Tech Xplore / Amorphous passivation strategy creates efficient, durable and flexible perovskite solar cells
Solar cells, devices that convert sunlight into electricity, are helping to reduce greenhouse gas emissions worldwide, promoting a shift toward renewable energy sources. Most solar cells used today are based on silicon, yet ...
Medical Xpress / New federal plan aims to use more donor organs, improve transplant safety
U.S. health officials unveiled proposed changes to the nation's transplant system, hoping to help more patients get lifesaving organs, even when donations aren't perfect.
Tech Xplore / 'Thermal diode' design promises to improve heat regulation, prolonging battery life
New technology from University of Houston researchers could improve the way devices manage heat, thanks to a technique that allows heat to flow in only one direction. The innovation is known as thermal rectification, and ...
