    What's Swimming In The River? Just Look For DNA

    Biologists have discovered they can track hard-to-see species in streams, ponds and even the ocean by sampling the water for DNA. Scientists say the technique is an important conservation tool: So far, it's been used to track declining giant salamanders and even locate a rare whale.
