Phys.org / Why cultivating drought-resistant plants disappoints: Soil physics may be the real bottleneck
Plants need water, light, and air to thrive. But when they transport water from the soil up to their leaves, they defy gravity. Scientists describe this astonishing phenomenon as "negative water potential," a form of negative ...
Medical Xpress / Could a new type of weight‑loss pill shake up the market? Here's what to know about orforglipron
A new type of daily pill has proven more effective for weight loss and blood sugar control than its currently available counterparts, according to a recent trial. The drug, known as orforglipron, could be a game-changer in ...
Tech Xplore / Bird‑like robots promise greater flexibility and control than drones
A bird banking in a crosswind doesn't rely on spinning blades. Its wings flex, twist and respond instantly to its environment. Engineers at Rutgers University have taken a major step toward building bird-like drones that ...
Phys.org / Superconducting altermagnets could carry spin without energy loss
Researchers have proposed that a newly identified class of magnetic materials could extend the zero-resistance currents of superconductors to electron spins. Publishing their calculations in Physical Review X, Kyle Monkman ...
Phys.org / Moons orbiting wandering exoplanets could be habitable—with one catch
Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David Dahlbüdding at the Max Planck ...
Phys.org / XRISM identifies gamma Cas X-ray origin, solving a 50-year-old stellar mystery
Visible to the naked eye in the constellation Cassiopeia, the star γ Cas has puzzled astrophysicists for half a century. It emits X-rays of an intensity and temperature incompatible with what one would expect from an ordinary ...
Medical Xpress / Radiotherapy rather than surgery may help reduce risk of lymphedema in patients with breast cancer
Patients with breast cancer may be able to avoid lymphedema, which can occur after surgery to remove lymph nodes in the armpit (the axilla), by having radiotherapy instead. New findings, presented at the 15th European Breast ...
Medical Xpress / Vivid dreaming makes sleep feel deeper, researchers discover
Researchers led by Guilio Bernardi at the IMT School for Advanced Studies Lucca in Italy have discovered a key relationship between dreaming and the feeling of having had a good night's sleep. Published in PLOS Biology, the ...
Phys.org / The evolutionary secret of the California poppy's alkaloids
Characteristic features of plants, such as their active ingredients or flower color, may have developed through very different evolutionary histories. This is shown by an international study on the orange-flowering California ...
Phys.org / Pike eat more as water warms, threatening native species
Rising temperatures in a Southcentral Alaska river have led to a hungrier population of invasive northern pike, a trend that could imperil native salmon and other fish species. A University of Alaska Fairbanks-led research ...
Phys.org / Stolen chloroplasts maintained by host-made proteins offer clues to plant cell origins
Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria that took up residence ...
Medical Xpress / Anthrax‑causing bacteria have dwelled in soil for centuries, cycling through people, animals and earth
The bacteria that cause deadly anthrax disease persist in the earth, a place their ancestors preferred over petri dishes and blood-filled tissues.
