Thought to dwell mostly near the ocean's surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and international colleagues reveals that these large and majestic creatures are actually among the deepest-diving ocean animals. "So little is known about these rays," said Simon Thorrold, a biologist at WHOI and one of the authors of the paper, published July 1, 2014, in the journal Nature Communications. "We thought they probably travelled long distances horizontally, but we had no idea that they were diving so deep. That was truly a surprise."

By measuring how fast Earth conducts electricity and seismic waves, a University of Utah researcher and colleagues made a detailed picture of Mount Rainier's deep volcanic plumbing and partly molten rock that will erupt again someday. "This is the most direct image yet capturing the melting process that feeds magma into a crustal reservoir that eventually is tapped for eruptions," says geophysicist Phil Wannamaker, of the university's Energy & Geoscience Institute and Department of Civil and Environmental Engineering. "But it does not provide any information on the timing of future eruptions from Mount Rainier or other Cascade Range volcanoes."

Chinese businessman Yi Zong decided to install charging stations himself after he purchased his Tesla earlier this year. He realized that charging his vehicle would be a problem in China because, well, there are few stations in that country. Zong installed recharging facilities on his own dime, or yuan as the case may be, in 16 cities between Beijing and his home in Guangzhou — a 3,573-mile corridor. Zong, one of the first Chinese owners of the Model S, calls his project the country’s "first electric-charging road," according to a report at Caixin Online, a Beijing-based media group.

El misterio detrás de los movimientos de las bandadas de estorninos podría explicarse por las zonas de luz y oscuridad creada mientras vuelan, sugiere una investigación reciente. La investigación, llevada a cabo por la Universidad de Warwick y publicada en la revista PNAS, encontró que los estorninos tienden a mantener una densidad óptima de la que se pueden recopilar datos sobre su entorno. Esto ocurre cuando se puede ver la luz a través de la manada en muchos ángulos, un estado conocido como la opacidad marginal. El patrón resultante de luz y oscuridad, formada conforme las aves intentan lograr la densidad necesaria, es lo que proporciona información vital para las aves individuales dentro de la bandada.

More extreme droughts, floods and wildfires – these are just some of the impacts of climate change that won't just occur in the distant future to our great-great grandchildren, but are happening now. To address the changing climate's current effects on communities in the U.S., President Barack Obama announced a plan to strengthen national infrastructure and help cities, states and tribal communities better prepare for and recover from natural disasters.
