Russian astronauts, or cosmonauts, have discovered living organisms clinging to the exterior of their International Space Station. The microscopic creatures were discovered during a space walk to clean the surface of the vessel, and they’ve reportedly been identified as a type of sea plankton. But scientists have no idea how they got there.

En un informe de las Naciones Unidas publicado en mayo, científicos de todo el mundo fueron llamados a unirse a la guerra contra las medusas. Según el informe, las medusas han abrumado el ecosistema marino como consecuencia de la sobrepesca de especies más competitivas que ellas, consumiendo huevos y larvas de peces de especímenes más débiles y la creación de lo que el informe denomina...

El Fracking está una vez más en problemas. Los científicos han encontrado que lo que se bombea en las rocas ricas en hidrocarburos, como parte de la técnica de fractura hidráulica de rocas (fracking, NT) para liberar el gas y el aceite atrapado en depósitos subterráneos, puede no ser completamente sano. El ingeniero ambiental William Stringfellow y sus colegas en el Laboratorio Nacional Lawrence Berkeley y la Universidad del Pacífico, dijeron a la reunión de la American Chemical Society en San Francisco, que...

In Italy, a man foraging for mushrooms was attacked when he happened upon a mother bear and her cubs. Part of a reintroduction and conservation program in Italy's northern Dolomites, the bear, named Daniza, was ordered to be captured and possibly killed. This has sparked social media outrage, prompting those on twitter to hashtag #iostocondanzia (I'm with Danzia). The outrage stems from a revelation that when mauling victim Daniele Maturi happened upon the bear, he did not immediately leave, but rather hid behind a tree to watch him. It is said the bear only charged when it spotted him watching from behind a tree (like a predator would do, thus provoking the bear).

More and more people are living in our cities. They are great places to live, exciting, good jobs, great night life, but also sometimes congestion and unhealthy air quality. The latter problems are improving, however. Efforts to make cities livable without driving are paying off. Bike lanes, bike sharing, and efforts to reduce auto traffic and congestion are helping to improve the air quality in our cities. The U.S. Environmental Protection Agency (EPA) this week released its Second Integrated Urban Air Toxics Report to Congress - the final of two reports required under the Clean Air Act (CAA) to inform Congress of progress in reducing public health risks from urban air toxics. "This report gives everyone fighting for clean air a lot to be proud of because for more than 40 years we have been protecting Americans – preventing illness and improving our quality of life by cutting air pollution - all while the economy has more than tripled," said EPA Administrator Gina McCarthy. "But we know our work is not done yet. At the core of EPA's mission is the pursuit of environmental justice - striving for clean air, water and healthy land for every American; and we are committed to reducing remaining pollution, especially in low-income neighborhoods."

Una investigación de la NASA ha revelado que la atmósfera de la Tierra contiene una inesperada cantidad de un compuesto destructor de ozono proveniente de una fuente desconocida, que hace décadas fue prohibido su uso en todo el mundo. El tetracloruro de carbono (CCl4), que alguna vez fue utilizado en aplicaciones tales como limpieza en seco y para apagar incendios, se reguló en 1987 bajo el Protocolo de Montreal junto con otros clorofluorocarbonos que destruyen la capa de ozono y...
