Well, blogs and all other electronics-related things. WTOP reports that University of Maryland researchers have found an alternative for the body and planet-harming lead used on most electronics. One of the reasons people are always harassing you to throw away your old electronics responsibly is that they contain lead which seeps out of them if you just toss them in the landfill. This achievement at UMD will allow manufacturers to use bismuth instead of lead.
WTOP also reports that some manufacturers are using bismuth in place of lead in ammunition, though they stop short of claiming it makes it healthier for you.
