Phys.org / Space station crew credits ultrasound machine for handling in-orbit health crisis
The astronauts evacuated last week from the International Space Station say a portable ultrasound machine came in "super handy" during the medical crisis.
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 / 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 / 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 / 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 / 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 / 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 / AI method advances customized enzyme design
Enzymes with specific functions are becoming increasingly important in industry, medicine and environmental protection. For example, they make it possible to synthesize chemicals in a more environmentally friendly way, produce ...
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. ...
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 / Increased soil salinity alters global inorganic carbon storage, finds study
A new global study shows that increasing soil salinity is systematically reshaping the storage and distribution of soil inorganic carbon (SIC), a key but often-overlooked part of terrestrial ecosystems. The findings, published ...
