Phys.org / How root growth is stimulated by nitrate: Researchers decipher signaling chain
When 200 natural accessions of the model plant Arabidopsis thaliana grown in a nitrate-enriched medium were compared, one observation stood out: some accessions formed significantly longer lateral roots than others. Genetic ...
Phys.org / Why some objects in space look like snowmen: Gravitational collapse may shed light on contact binaries
Astronomers have long debated why so many icy objects in the outer solar system look like snowmen. Michigan State University researchers now have evidence of the surprisingly simple process that could be responsible for their ...
Phys.org / Rare fossil at Montana museum records Tyrannosaurus attack
A fossil on display at Montana State University's Museum of the Rockies reveals how dinosaurs in the Tyrannosaurus genus may have subdued prey, and the specimen is the focus of a new collaborative research publication between ...
Tech Xplore / Will you notice this ad? New AI model predicts attention from content context
Researchers at the University of Maryland and Tilburg University in the Netherlands have produced an AI-driven innovation to reshape how marketers place digital ads. AdGazer, a predictive tool, evaluates both an advertisement ...
Medical Xpress / Mechanism behind immunotherapy resistance in lung cancer identified
Mayo Clinic researchers and collaborators have identified a previously unrecognized way lung tumors weaken the immune system, helping explain why many patients do not respond to immunotherapy and pointing to a potential new ...
Medical Xpress / Toxic exposure creates disease risk over 20 generations, epigenetic inheritance study suggests
A single exposure to a toxic fungicide during pregnancy can increase the risk of disease for 20 subsequent generations—with inherited health problems worsening many generations after exposure. Those are the findings of ...
Phys.org / Storms reveal rare 2,000-year-old footprints on Scottish beach
Storms that recently ravaged Britain's coastline have revealed 2,000-year-old footprints on an Angus beach—one of only a handful of locations in the U.K. where markings of this kind have ever been discovered. The imprints ...
Phys.org / Honey bees navigate more precisely than previously thought
A team from the University of Freiburg led by neurobiologist and behavioral biologist Prof. Dr. Andrew Straw studied the flight behavior of honey bees. Using a drone, the researchers tracked honey bees as they flew between ...
Phys.org / Why people say they care about ethical shopping but often buy differently
Many Canadians say they care about ethical products. They want coffee that supports farmers, chocolate made without child labor and everyday goods that are better for the environment.
Phys.org / A few weeks of X's algorithm can make you more right-wing—and it doesn't wear off quickly
A new study published in Nature has found that X's algorithm—the hidden system or "recipe" that governs which posts appear in your feed and in which order—shifts users' political opinions in a more conservative direction.
Medical Xpress / Ancient mind-body practice proven to lower blood pressure in clinical trial
A traditional Chinese mind-body practice that combines slow, structured movement, deep breathing and meditative focus lowered blood pressure as effectively as brisk walking in a large randomized clinical trial published in ...
Phys.org / Blood marker from dementia research could help track aging across the animal world
A protein called neurofilament light chain (NfL)—studied in humans in the context of neurodegenerative diseases and aging—is also detectable in the blood of numerous animals, and NfL levels increase with age in mice, ...
