And, by providing a more complete picture of the marine web of life, it is another step toward managing the Gulf of Maine as an ecosystem ?one of the primary goals of fisheries laws in the U.S. and Canada and of recent ocean commi...

New nano-canary in the nanotoxicology coalmine: The body itself

...s, live cell FTIR spectroscopy is expected to be a sentinel of exposure to help identify the physico-chemico properties of nanoparticles that mediate biological activity, without bias of what that biological activity represents. The PNNL scientists are also developing infrared transparent chemistries that ...
