10/25/2007: "Environmental toxins change the DNA of embryos"

Changes in gene expression patterns in zebrafish embryos resulting from exposure to environmental toxins can identify the individual toxins at work, according to new research. The genetic response of zebrafish to each toxin can be read like a barcode, offering researchers a potential method for identifying the effects of the toxin on developing vertebrate embryos.

[ Same is true of humans. All those exhaust pipes, decaying plastics, and intense factories are making your children mutant idiot criminals. Awesome. ]
