#Nuclear: Radioactive water is leaking from a hole which has opened up in the main vessel of Fukushima’s number 1 reactor, according to TEPCO, the plant operator. “There must be a large leak,” said Junichi Matsumoto, a general manager at TEPCO. “The fuel pellets likely melted and fell, and in the process may have damaged… the pressure vessel itself.”

Meanwhile, Greenpeace’s radiation monitoring team has reported high levels of radiation in seaweed near Fukushima. Tests of seaweed samples, collected up to 40 miles out to sea, showed significant levels of contamination, raising fears for public health as it accumulates in the foodchain.

#Arctic: Documents released by Wikileaks show that a race to control the Arctic and its natural resources is creating military tension in the region. As the ice melts, previously inaccessible oil reserves are becoming open to exploration, which Arctic nations are vying to control. The leaked cables reveal Russian and NATO diplomats’ anticipation of conflict, as the US and Russia attempt to strengthen their claims on this pristine wilderness. Greenpeace campaigner Ben Ayliffe said: “They’re preparing to fight to extract the very fossil fuels that caused the melting in the first place. It’s like pouring gasoline on a fire.”

#Nuclear: Ever wondered what it would be like trying to survive in a post-nuclear disaster environment? Four Italians are doing just that – and they say they won’t leave their locked “bunker” until Italy’s nuclear referendum on June 12. Living under strict anti-radiation measures, the four men are live-streaming their experiences on the internet. Watch this apocalyptic version of Big Brother here.
