Either Way, We Don't Want It in Our Apartments

Two New York City high school students took to the streets to collect more than 200 samples, including hair from classmates, food, and cockroaches, to examine their DNA barcodes, reports NPR's health blog Shot. Brenda Tan and Matt Cost confirmed that their classmates were human (shucks) and identified some mislabeled food. They might have, though, identified a new species of cockroach. That roach, collected from an Upper West Side apartment, varied from the roaches in the Barcode of Life Database by about four percent and most species vary by one percent or less.
