It’s strange what gets massive amounts of press, sometimes. This story’s been out there for less than 24 hours, and it’s already got a lot of copies floating around: The Engineer R&D Mag PhysOrg Science Daily New Scientist Wired UK
Summary: Scientists have developed a soap that has magnetic properties, by incorporating iron into the soap particles. This will allow the stuff (and any oil or dirt that it’s glommed onto) to be removed more easily from water, which would be really handy for cleaning up oil spills in environmentally sensitive areas. It’s still in the development stages, but the point is that it’s possible to do it, so something with practical applications should appear eventually.
