    Secret Molecular Barcodes Could Be Used To Fight Counterfeits 

    French scientists have created the first synthetic polymers that can store information as bits of 0s and 1s. You might think of it as a highly simplified version of DNA, another molecule that is very, very good at storing information. These new polymers could one day replace DNA in the burgeoning field of molecular barcoding.

    The Secret 1949 Radiation Experiment That Contaminated Washington

    The physicists who invented the nuclear bomb worked out of Los Alamos in New Mexico, but the people who did the dirty work of making the bombs were in Hanford, Washington. Throughout the Cold War, Hanford churned out plutonium for our nuclear arsenal. It was also, conveniently, a place to experiment with radiation.
