Engineers last week finished a work on one of the world’s most ambitious conservation projects: a doomsday vault carved into a frozen mountainside in the archipelago of Svalbard, a few hundred miles from the North Pole. Over the next few weeks, the huge cavern—backed by the Norwegian government and the Gates Foundation—will be filled with more than a million types of seed and will be officially opened in February next year. "This will be the last refuge for the world’s crops," said Cary Fowler, of the Rome-based Global Crop Diversity Trust, which is building the vault. "There are seed banks in various countries round the globe, but several have been destroyed or badly damaged in recent years. We need a place that is politically and environmentally safe if we are going to feed the planet as it gets hotter." About 500 seeds from about 1.5 million types of crop—donated by individual countries—will be placed in envelopes and about 400-500 of these envelopes are stored in a single box. Boxes will then be stacked like library books along shelves inside the vaults.

Cohen and his colleagues had found in a previous study that happier people seemed less susceptible to catching a cold, but some questions remained as to whether the emotional trait itself had the effect. For the new study, the researchers had 193 healthy adults complete standard measures of personality traits, self-perceived health and emotional style. Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy, tense and hostile had a negative style. The researchers gave them nasal drops containing either a cold virus or a particular flu virus. Over the next six days, the volunteers reported on any aches, pains, sneezing or congestion they had, while the researchers collected objective data, like daily mucus production. Cohen and his colleagues found that based on objective measures of nasal woes, happy people were less likely to develop a cold.

Last Sunday, China’s central bank governor Zhou Xiaochuan said if necessary, the nation will consider widening the yuan’s trading band. But any change in the yuan’s floating band will depend on the global economic situation and it’s not the only tool the country would use to make its currency moreflexible, Zhou said at the Group of 20 meeting in Cape Town, South Africa. China widened the yuan’s daily trading band against the U.S. dollar from plus or minus 0.3 percent to 0.5 percent in May. However, market observers said some commercial banks are ordered by the central bank to hand in reserve requirements in foreign currencies next week, which will translate into demand for the U.S. dollar. This Will somehow help slow down RMB’s appreciation against the greenback in the coming few days.
