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.

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.

Los astrobiólogos de los Estados Unidos y Alemania, registraron el nivel más alto conocido de la radiación UV solar que llega a la superficie terrestre. Esto fue hace unos 10 años. El 29 de diciembre de 2003, el índice de radiación Ultra Violeta (IUV) alcanzó su punto máximo, alcanzando un abrasador 43.3 sobre las montañas de los Andes en Bolivia. Para poner esto en contexto, un bañista en los Estados Unidos espera una IUV de 8 o 9 en un día de verano. Incluso con esos números, no se puede escapar el día sin las quemaduras solares. No obstante, le ha tomado a los científicos 10 años para detallar un informe de estos datos, teniendo en cuenta las variables y anomalías monitoreadas desde una red internacional de dosímetros (o Eldonets por sus siglas en inglés) que miden la radiación UV en todo el mundo. Este sistema se compone de más de 100 estaciones en los 5 continentes para dar cuenta de la variación atmosférica sobre cada estación.

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."

You have probably heard that melting permafrost is a big contributor to increasing the levels of greenhouse gases in our atmosphere, and that melting permafrost may even cause an unstoppable acceleration of global warming. New research, however, supported by the National Science Foundation (NSF), counters this widely-held scientific view that thawing permafrost uniformly accelerates atmospheric warming, indicating instead that certain arctic lakes store more greenhouse gases than they emit into the atmosphere. The study, published this week in the journal Nature, focuses on thermokarst lakes, which occur as permafrost thaws and creates surface depressions that fill with melted fresh water, converting what was previously frozen land into lakes.

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.
