New viruses had all the building blocks of the human virus, and lab exeriments found that some are equipped with the same capacity to enter human cells.
Eco Escuela : Ideas para habitar el planeta by Cabrales, Benjamin , Casadiego . El documento relata la historia de la comunidad de Belén de los Andaquíes, Caquetá, que se organizó en tiempos de guerra para defender su entorno y en menos de treinta años lograron transformar una región caracterizada por la extracción de indiscriminada de los recursos naturales, en un lugar protector del agua y los bosques amazónicos como respuesta al reto del cambio climático. Es a partir de esas historias y ese contexto regional donde se inscribe el proyecto Implementación de un Centro de Educación y Capacitación en utilización de Energías Renovables para protección y adaptación al Cambio Climático.. “Los resultados de la expedición Colombia Bio en el Parque Municipal Andakí revelaron que la estrategia de los lugareños para cuidar la Biodiversidad de Belén de los Andaquíes produce buenos resultados. En sólo 26.000 hectáreas aparecieron 47 especies nuevas para la ciencia”.

The vision captured by Australian Customs officers in the Southern Ocean is so sensitive the Government fought for years to keep it secret, saying it could damage relations with Japan.
The Ebola epidemic in West Africa may have surprised most of the medical establishment – this is the first such outbreak in the region – but the risk had been steadily rising for at least a decade. The risk had grown so high, in fact, that this outbreak was almost inevitable and very possibly predictable.All that was needed was to see the danger was a bat’s eye view of the region. Once blanketed with forests, West Africa has been skinned alive over the last decade. Guinea’s rainforests have been reduced by 80%, while Liberia has sold logging rights to over half its forests. Within the next few years Sierra Leone is on track to be completely deforested.This matters because those forests were habitat for fruit bats, Ebola’s reservoir host. With their homes cut down around them, the bats are concentrating into the remnants of their once-abundant habitat. At the same time, mining has become big business in the region, employing thousands of workers who regularly travel into bat territory to get to the mines.
The awful news that all but two penguin chicks have starved to death out of a colony of almost 40,000 birds is a grim illustration of the enormous pressure Antarctic wildlife is under. The causes of this devastating event are complex, from a changing climate to local sea-ice factors, but one thing penguins, whales and other marine life don’t need is additional strain on food supplies.
The Guggenheim’s alarming action continues a growing worldwide trend in which threats of violent protest are silencing artistic expression and posing a danger to free speech in general. Whether or not the provocations of artists are defensible or morally unacceptable, we need to take an uncompromising position against threats of violence. When cultural institutions cave in to such threats, others who are convinced of the moral rectitude of their cause are encouraged to embrace similar tactics. This time it is animal rights activists. Next time it could be religious or political extremists.
I was already midway through my 13 years of working to improve fishery sustainability in the Galápagos and throughout Latin America when I had my “aha!” moment. What I came to realize is that fishers are not the enemies of sustainability or ocean health, but rather the best allies that humankind can have to ensure the conservation of marine ecosystems, food security and poverty eradication around the world. We just need to understand their motivations, needs and concerns in order to help them create the conditions to move fisheries toward sustainability, while not forgetting that crises represent the best opportunities for change.
After years of campaigning to protect grizzly bears from being senselessly killed by trophy hunters in British Columbia, conservationists are finally
Classic anthrax is caused by Bacillus anthracis, which tends to strike ungulates (hoofed mammals) in seasonal outbreaks in arid locales, such as the African savannahs. The bacteria can cause infection in skin, lungs, or intestines. In humans, B. anthracis causes ghastly skin lesions and severe respiratory and intestinal infections—which have mortality rates as high as 85 to 60 percent, respectively.The alternative anthrax bacteria appear to cause an identical anthrax disease in animal models. But, those bacteria aren’t B. anthracis; they’re cousins, B. cereus, commonly found in soil and food. Usually, these are relatively harmless, with some strains known to cause a minor fraction of food poisoning cases. But the ones causing alternative anthrax are different. They just so happen to have gotten their grips on B. anthracis’ virulence plasmids—circular, shareable bits of DNA that contain the genetic code for their disease-causing gene products.
This year’s “dead zone,” where oxygen levels are so low they threaten fish and other small aquatic life, is about 50 percent larger than normal. The average size of the dead zone over the last 31 years has been 14,037 square kilometers, according to Nancy Rabalais, a researcher at Louisiana State University who has long studied the issue. The dead zone was likely even larger than what the scientists found, but there was insufficient time on board the ship to measure its entire extent.
