The town’s main street is only two blocks long right now; its string of smaller businesses survive generally on tourists who come to hike the nearby Arizona Trail, bike on serene mountain roads or bird view. But, High Country News further reports: [M]ore than 145 million ounces of silver and 7.2 billion pounds of manganese lie buried under the hills, and plans are underway that could re-begin Patagonia’s old industry on a straight larger level: an open pit mine 4,000 feet wide and 1,500 feet deep, just six miles southeast of town. Wildcat Silver, a Canadian mining business, is definitely behind the proposed Hermosa Mine, which supporters says provides 300 jobs and a boost to the local economy. Perpetual water reduction The site also happens to be in the same watershed that feeds into Patagonia’s normal water, say occupants and activist groups.One of the tasks is led by Assistant Prof Toh Chee Seng of the National University of Singapore , who, in close collaboration with dengue and antibody analysis experts from A*STAR’s SIgN, is developing an ultra-sensitive, low priced biosensor probe system for fast recognition of the dengue virus. The system comprises a channel of nanometre-scale attached with antibodies that may bind and distinguish between your four serotypes of the dengue virus, in addition to a detector. ‘With this technique, we will be able to sense low amounts of the dengue virus in sufferers’ blood samples, and therefore reduce the right time necessary for analysis from the existing six hours to less than one hour. If successful, this system may also be applied to rapid recognition of multiple illnesses at clinics further, schools and offices during large-scale outbreaks of infectious diseases,’ said Associate Prof Toh.
