Phys.org / One-way sound tunnel offers novel way to control acoustic waves
(Phys.org)—Scientists have designed and built an acoustic one-way tunnel that allows sound to pass through in one direction only while blocking it from passing through in the opposite direction. The tunnel is completely ...
Phys.org / Macroscopic quantum phenomena discovered in ice
(Phys.org)—Scientists have discovered an anomaly in the properties of ice at very cold temperatures near 20 K, which they believe can be explained by the quantum tunneling of multiple protons simultaneously. The finding ...
Phys.org / Earlier ultra-relativistic freeze-out could revive a decades-old theory for dark matter
A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from Standard Model particles far earlier than previous theories had suggested.
Phys.org / New limit to the Church-Turing thesis accounts for noisy systems
(Phys.org)—The question of what a computer is capable of, and what it is not, has intrigued computer scientists since the 1930s, when Alonzo Church and Alan Turing began investigating the capabilities and limits of computers. ...

If a can of coconut water and a banana smoothie had a baby, it might be banana water. The latest plant-based hydration beverage on the market is being touted as "the peel good beverage" that offers "a bunch of nutrients." ...
Phys.org / Quantum Cheshire Cat effect may be explained by standard quantum mechanics
(Phys.org)—"A grin without a cat" is how Lewis Carroll describes the Cheshire Cat's mysterious way of disappearing while leaving its grin behind in his 1865 classic, Alice in Wonderland. The fanciful character raises a ...
Phys.org / Officials suspect bird flu after 12 swans die at Orlando's Lake Eola
A dozen of the iconic swans that live in the heart of downtown Orlando, Florida, have died in recent days of an unknown cause, leading officials to suspect that bird flu is to blame.
Phys.org / How a new diet of penguins is changing puma behavior and social lives in Patagonia
Penguins in the coastal steppes of Argentina have a new enemy to worry about: the increasing numbers of pumas in Monte León National Park (MLNP). These powerful mountain cats were once on the brink of disappearing from this ...
Phys.org / What Renaissance readers left behind in haircare books
What if the pages of an old book could tell us who touched them, what medicines they made, and even how their bodies responded to treatment?
Medical Xpress / Do marathons damage your heart? Decade-long study shows no long-term cardiac harm
A marathon pushes the human body close to its limits. Legs tire, lungs burn and the heart works hard for hours on end. For years, that strain has raised an uncomfortable question: does running 26 miles actually damage the ...
Tech Xplore / Lowering barriers to explainable AI: Control technique for LLMs reduces resource demands by over 90%
Large language models (LLMs) such as GPT and Llama are driving exceptional innovations in AI, but research aimed at improving their explainability and reliability is constrained by massive resource requirements for examining ...
Tech Xplore / California crypto company accused of illegally inflating Katy Perry NFTs and fraud
Four years ago, California startup Theta Labs' cryptocurrency was soaring, and its future appeared bright when it landed a partnership with pop star Katy Perry.
