Researchers Discover Eleven New Species of Rain Frogs in Ecuador

The rain frogs comprise a unique group lacking a tadpole stage of development. Their eggs are laid on land and hatch as tiny froglets. Image credit: BIOWEB-PUCE.Nadia Paez, a PhD student at the University of British Columbia, and Pontifical Catholic University’s Professor Santiago Ron have discovered eleven new species of the frog genus Pristimantis living in the Ecuadorian Andes. The rain frogs comprise a unique group lacking a tadpole stage of development. Their eggs are laid on land and hatch as tiny froglets. Image credit: BIOWEB-PUCE. Pristimantis…

Researchers Find First Candidate for 3D Quantum Spin Liquid

A 3D representation of the spin-excitation continuum -- a possible hallmark of a quantum spin liquid -- observed in a single crystal sample of cerium zirconium pyrochlore. Image credit: Tong Chen / Rice University.A quantum spin liquid is a state of matter where unpaired electrons’ spins, although entangled, do not show magnetic order even at the zero temperature. The realization of a quantum spin liquid is a long-sought goal in physics. In a paper published in the journal Nature Physics, physicists from Rice University and elsewhere show that cerium zirconium pyrochlore (Ce2Zr2O7), in its single-crystal…

Study: In Hot Climates, Pavements Can Be Hot Enough to Cause Second-Degree Burns within Seconds

Pavement burns account for significant burn-related injuries in the Southwestern United States and other hot climates with nearly continuous sunlight and daily maximum temperatures above 100 degrees Fahrenheit (38 degrees Celsius). Image credit: Johannes Plenio.In a study published recently in the Journal of Burn Care & Research, a team of researchers reviewed all pavement burn injury admissions into a Las Vegas area burn center, and compared the outdoor temperatures at the time of each patient admission to, in essence, determine how hot is too hot. Pavement burns account for significant burn-related injuries in the Southwestern United States and other…

Smoke from African Fires is Fertilizing Amazon Rainforest, Atlantic and Southern Oceans: Study

Using satellite data and models, Barkley et al identified a previously underestimated source of soluble phosphorus: biomass burning aerosol transported from southern Africa that can supply phosphorus to the Amazon, Tropical Atlantic and Southern oceans. Image credit: Scite / University of Miami.Smoke from fires in southern Africa is the largest contributor of phosphorus — an important agricultural fertilizer — to the Amazon rainforest, Tropical Atlantic and Southern oceans, according to new research published in the Proceedings of the National Academy of Sciences. Using satellite data and models, Barkley et al identified a previously underestimated source of soluble phosphorus:…
