Phys.org / Camera traps snap nearly three times more images of endangered Sumatran tigers than before
Destroyed habitats, poaching, and prey depletion have dramatically reduced tiger habitats around the world. Today, tigers occupy just 5–10% of their historical habitats. But on the Indonesian island of Sumatra, an important ...
Phys.org / Fearless frogs feast on deadly hornets
A remarkable resistance to venom has been discovered in a frog that feasts on hornets despite their deadly stingers. This frog could potentially serve as a model organism for studies on mechanisms underlying venom tolerance.
Phys.org / Astronomers find vast spinning filament of galaxies 140 million light-years away
An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a "razor-thin" string of galaxies embedded in a giant spinning cosmic filament, 140 million light-years ...
Medical Xpress / Marriage and emotional support may protect against obesity through brain–gut connection
Strong social relationships, particularly high-quality marriages, may help protect against obesity by influencing a complex communication system between the brain and gut, according to new research by UCLA Health.
Phys.org / Degraded peatlands emit nearly twice as much greenhouse gas as previously thought, study finds
For the first time, researchers have produced a detailed, high-resolution map of peatlands in the EU, showing that these areas emit twice as much greenhouse gases than previously thought. The research, led by eco-hydrologist ...
Phys.org / Over 16,000 dinosaur footprints identified along a Bolivian shoreline
A fossil site in Bolivia preserves thousands of traces of dinosaurs who walked, ran, and swam along an ancient coastline, according to a study by Raúl Esperante of the Geoscience Research Institute, California, U.S., and ...
Medical Xpress / Chronic cannabis use, vomiting and compulsive bathing—symptoms of a hidden syndrome
Researchers at the Jane Addams College of Social Work at the University of Illinois Chicago have found that cannabinoid hyperemesis syndrome, a vomiting condition tied to chronic cannabis use, rose sharply in US emergency ...
Phys.org / Is anyone really misled by the term 'veggie burger?' Our research suggests consumers are savvy
The European Parliament recently backed changes to the rules around the labeling and marketing of plant-based meat alternatives. New definitions specify that words like "burger," "sausage," or "steak," refer exclusively to ...
Phys.org / How Ramanujan's formulae for pi connect to modern high energy physics
Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More recently, scientists have ...
Phys.org / Smart material instantly changes colors on demand for use in textiles and consumer products
Scientists have developed a revolutionary technique for creating colors that can change on command. These are structural colors that don't rely on dyes or pigments and can be used for display signage, adaptive camouflage ...
Medical Xpress / Airplane and hospital air is cleaner than you might think
When it comes to the air in public places, germophobes can breathe a bit easier. According to a new Northwestern University study, the ambient air on airplanes and in hospitals mostly contains harmless microbes typically ...
Phys.org / 10-thousand-year-old genomes from southern Africa change picture of human evolution
In southern Africa, a group of people lived in partial isolation for hundreds of thousands of years. This is shown in a new study based on analyses of the genomes of 28 people who lived between 10,200 and 150 years ago in ...
