Polar bear DNA found from tracks in snow, in conservation step
Polar bear DNA has been isolated for the first time from footprints left in the snow on an Arctic island, a breakthrough that could help scientists better protect rare and endangered wild animals, experts said on Tuesday. Scientists often spend days tracking rare animals such as snow leopards or orangutans for samples of DNA, for instance from hair or faeces, to understand their movements, monitor their populations and propose ways to protect them.
