Phys.org / Battery-free nano-sensors could pave the way for next-generation wearables
Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to scientists at the University of Surrey.
Phys.org / Nash equilibria: The hidden math behind predator–prey behaviors
Animal survival depends on effective attack and defense strategies, yet how these behaviors arise remains unclear. Addressing this question, a recent study shows that predator and prey behaviors emerge naturally as stable ...
Phys.org / Arctic cloud and ice formation affected by Russian river runoff as region studied for first time
Organic matter carried in rivers to the Russian part of the Arctic Ocean may be creating more clouds and keeping the region cooler, a new study has found.
Phys.org / Study reveals why light-driven chemical reactions often lose energy before bond-breaking
Florida State University researchers have discovered a pathway within a certain type of molecule that limits chemical reactions by redirecting light energy. The study could enable development of more efficient reactions for ...
Phys.org / AI model that found 370 exoplanets now digs into TESS data
Scientists have discovered over 6,000 planets that orbit stars other than our sun, known as exoplanets. More than half of these planets were discovered thanks to data from NASA's retired Kepler mission and NASA's current ...
Phys.org / Rewilding corn reveals what its roots forgot
Corn is a colossal grain in the global food and feed chain, with the U.S. producing roughly 30% of the world's supply, or nearly 278 million metric tons in the 2024–25 growing season alone. But its journey from wild grass ...
Phys.org / Single enzyme streamlines production of all four RNA building blocks
A single enzyme that can generate all four nucleoside triphosphates, the building blocks of ribonucleic acid (RNA), has been identified by researchers at the Institute of Science Tokyo. The study was published online in the ...
Phys.org / Copper-carrying compound targets and kills MRSA bacteria by mimicking iron
A research team at the University of Arizona College of Medicine–Tucson is developing a drug that works in combination with copper to kill bacteria, including those that cause MRSA, a type of staph infection that is resistant ...
Phys.org / Stress-reduction molecule has potential to treat aging and metabolic disorders
University of Queensland researchers say the discovery of a new stress reduction role for a naturally occurring molecule in the body could lead to new drugs and treatment for metabolic disorders and aging.
Phys.org / Rainfall–salinity link sustains prolonged La Niña events, study reveals
La Niña—a climate phenomenon characterized by unusually cool sea surface temperatures in the central and eastern tropical Pacific Ocean—can persist for multiple years, exerting significant climate impacts worldwide. ...
Phys.org / 2D topological crystalline insulator turns decade-old prediction into reality
Physicists from University of Jyväskylä and Aalto University (Finland) have experimentally realized a two-dimensional topological crystalline insulator. This is a quantum material that has been theoretically predicted for ...
Phys.org / Aging zoo animals threaten long-term species conservation goals
Many mammal populations in European and North American zoos are aging—a trend that jeopardizes the long-term viability of so-called reserve populations and, with it, a core mission of modern zoos in global species conservation. ...
