It’s the feedstock for the most heavily used nuclear agent in diagnostic medicine.Tiny metal nanoparticles can damage DNA, essentially by triggering toxic gossip. Biologists can tell a lot about how living things evolved by rooting around in their genes, comparing snippets of DNA from supposedly related — or unrelated — species. This only works, of course, if catalogs of those DNA snippets exist. Which they largely don’t yet — but could in the not-too-distant future. At least, that is, if a consortium of researchers gets its way — and a boatload of money.
