Phys.org / New photonic crystal method improves single-photon sources for quantum networks
Quantum communication promises many advantages over today's standard technologies, including absolutely secure transmission of large amounts of data. However, it requires single photons—and generating them is very difficult. ...
Phys.org / Rare satellite data reveal major limits in flood models
The Kakhovka Dam in southern Ukraine was destroyed on June 6, 2023. The event unleashed a catastrophic flood that forced thousands of residents to evacuate their communities as water levels rose 10 feet (3 meters) above normal.
Phys.org / Secrets of a mystery mammal from Patagonia revealed at last
Eight years of painstaking research on the virtually unknown Wolffsohn's viscacha have helped to shine the spotlight on this super-rare South American rodent and catalyze the conservation action it so urgently needs.
Phys.org / A new mathematical tool to uncover 'who eats whom' in nature
Understanding "who eats whom" is the key to keeping our oceans alive—and our dinner plates full. However, this invisible network that makes up the food chain can unravel with the pull of just one thread. Overfish one species, ...
Phys.org / Existing drug could treat invasive canine oral tumors
A benign but invasive canine oral cancer is often mistaken for a similar malignant one, leading to misdiagnoses in close to a third of cases. But a new diagnostic tool can now distinguish between the two, according to a new ...
Phys.org / Experiment shows how AI discoveries can shape human cultural evolution
Artificial intelligence can develop solutions that humans would be unlikely to discover on their own. But what happens when machines do more than solve individual problems and actually discover entirely new solution strategies? ...
Phys.org / 'Switchable' smart gel may pave way for next-gen drug delivery and sensing tech
University of Birmingham scientists have developed a new material that changes from a gel to a liquid-like state under ultraviolet light and can be rebuilt using heat or dismantled by acid.
Phys.org / New bone analysis challenges long-held theory on farming's arrival in Ireland and Great Britain
New research led by University College Dublin has rewritten a key chapter in Irish prehistory, revealing that bones long thought to mark the beginning of farming in Ireland belong to bear and wild boar, not cattle.
Phys.org / Climate doom may discourage climate action, but there's a way to counter it
Every summer is getting hotter. Wildfires are blazing, and the worst is yet to come. There's nothing to be done—we're doomed! Sound familiar?
Phys.org / Plants could transform how scientists measure the climate benefits of tidal marshes
Growing up in New Jersey, Emily Wilson regularly passed tidal marshes without giving them much thought. They were part of the coastal landscape—stretches of green and blue she saw from the road.
Phys.org / Novel plastic turns into a gas when heated—then reforms once cooled
In a study published in Macromolecules, researchers introduce a novel polymer that could simplify how materials are applied, removed and recycled by eliminating several complex processing steps used today.
Phys.org / Curved surfaces reshape active materials, localizing vibrations near defects
Many materials, both living and engineered, are powered from within. Scientists have thoroughly investigated how such 'active' materials operate, but so far, mostly in circumstances where the curvature of the environment ...
