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.
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 / 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 / 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 ...
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 ...
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 ...
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 / Free climbers discover remnants of ancient sea turtle stampede in Italy
Rocks have been found to hold many traces of Earth's ancient history, but usually geologists have to seek them out. Every once in a while, however, these imprints of times past are found by unsuspecting visitors. This occurred ...
Phys.org / Interstellar object covered in 'icy volcanoes' could rewrite our understanding of how comets formed
Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes. Researchers also discovered that the ...
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 / 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 ...
