| Our pick of today's science stories Metamorphosis. Physicists have found the first direct proof of a metamorphosis between 'muon' and 'tau' neutrinos (Nature news story). The results come from the OPERA experiment, which made headlines in 2011 after it announced that it had clocked neutrinos travelling faster than light, in apparent violation of Einstein's special theory of relativity (Nature news story). Buzzy work. Almost 80% of crop pollination by wild bees is provided by just 2% of the most common species. (BBC; Nature Communications paper) Export rules. Changes to US national-security regulations could dramatically affect how researchers collaborate with foreign scientists and industry. (Nature news story) MERS watch. Public-health measures are working in the fight against the MERS in South Korea. But it could be several weeks before the outbreak is declared officially over. (Nature news story) Martian methane. Methane has been found in meteorites from Mars. Scientists have suggested that microbes back on the Red Planet could live off the methane, just as some bacteria do in extreme environments on Earth. (Space.com; Nature Communications paper) Anti-ageing. Regulators are being asked to think of ageing as a treatable condition, by considering medicines that delay ageing-related disease as legitimate drugs. (Nature news story) Graphene boom. 'Wonder material' graphene is being made in record volume, but it still lacks a killer application that will see it hit the mainstream (Nature news story). Meanwhile, a wave of innovative flat materials is following in graphene's wake (Nature feature story). Disaster zone. The number of natural disasters has more than doubled since 1980. But the science of natural hazards is too fragmented to influence policy effectively, and experts say a more integrated approach to disaster-risk management is needed. (Nature comment piece) Today's good read The power generated by the Navajo Generating Station, the West's largest power-generating facility, enables a modern wonder. It drives a set of pumps 325 miles down the Colorado River that heave trillions of gallons of water out of the river and send it shooting over mountains and through canals. This achievement, however, is gained at an enormous cost. Every hour the Navajo's generators spin, the plant spews more climate-warming gases into the atmosphere than almost any other single facility in the United States. Alone, it accounts for 29 percent of Arizona's emissions from energy generation. Read more: Inside the power plant fuelling America's drought on Matter.
