In collaboration with Stony Brook University (SBU), Brookhaven National Laboratory (BNL), and the American Museum of Natural History (AMNH), the DNA Learning Center (DNALC) of Cold Spring Harbor Laboratory announces Barcode Long Island (BLI). With funding from the National Institutes of Health, the project mission is for students to gain an intuitive understanding of the crucial interdependence between humans and the natural environment. Over the course of five years, BLI will use DNA barcoding to explore, document, and track the biodiversity on and around Long Island, through independent and distributed experiments by student research teams, led by trained Long Island educators. BLI will provide students with real and relevant research experience while they contribute to our knowledge of their environment.
