Tech Xplore / The impact of all New Zealand's power sources from cradle to grave
A first national-scale study on the lifetime impact of New Zealand's electricity, transport, and heat sources shows road transport is a "prime target" for electrification. Scientists looked at how 15 energy sources affect ...
Medical Xpress / Innovative surgery relieves chronic leg and arm swelling
Advances in cancer treatment mean more people are living longer after a cancer diagnosis. But some survivors develop lymphedema—long-term swelling in the arms, hands, legs or feet that can cause pain, limit movement and raise ...
Phys.org / Shredded stars reveal how black holes ignite trillion-sun flares
Supermassive black holes are among the most enigmatic objects in the universe. They typically weigh millions or even billions of times the mass of the sun and sit at the centers of most large galaxies. At the heart of the ...
Phys.org / Ultrasound creates light inside the body, opening a new path to targeted treatments
Light has an increasing number of applications in biology and medicine—it can be used to stimulate cell growth, manipulate neural signals, and treat some cancers—but it doesn't easily pass through tissue. Most methods to ...
Tech Xplore / Tiny battery-free tags turn radio waves into a new way to track breathing at home and in hospitals
The same wireless technology that can track your cat or locate an item in a warehouse can also monitor your breathing. Researchers at Chalmers University of Technology, Sahlgrenska University Hospital and the University of ...
Tech Xplore / AI-guided snakebot unlocks rolling move that doubles speed per unit power
Snake-like robots represent the future of rescue. Their slender bodies allow them to navigate narrow spaces, uneven terrain, and water surfaces, entering places that would be hazardous for humans. This could potentially save ...
Phys.org / Rapid melatonin test can help astronauts and others easily monitor their biological rhythm
A simple test developed at Washington State University could eventually allow astronauts and others in round-the-clock occupations to monitor their biological rhythms in just minutes using a drop of blood, a paper test strip, ...
Medical Xpress / How long does a transplanted heart last?
Heart transplant surgeon Raymond Lee, MD, explains what patients can expect after a heart transplant—including how long the heart will last. The average lifespan of a transplanted heart is about 10 years, though outcomes ...
Tech Xplore / These restless materials don't just bend under pressure—they snap, crawl, walk and dig on their own
When we think of materials, we usually think of substances like metal, concrete, glass or rubber. What these examples have in common is that they are inactive: when pushed, pulled, shifted or sheared they may move or deform, ...
Phys.org / Global warming is changing the hatching of bees and wasps
A large-scale experiment shows that warmth brings bees and wasps out of hibernation earlier—leaving some of them with poorer starting conditions. This is particularly true for species in cooler regions that emerge during ...
Phys.org / Smart cable sharing gives quantum computers a big boost
A major obstacle in the development of powerful quantum computers is the growing number of cables required to control a computer as the number of qubits increases. Researchers at Chalmers University of Technology in Sweden ...
Phys.org / Glaciers may flow into the ocean more quickly than we think
Models of glacial flow and retreat rely on estimates of glacial ice viscosity, the measure of the ice's resistance to flow. Ice viscosity is dependent on the stress applied to the glacier. Most ice sheet models use a standard ...
