Wisconsin chemists have identified a new species of iron VI, which binds nitrogen, and is different from ferrate (iron VI plus oxygen). This is pretty cool. Also in cool chemistry news, researchers have found that Han purple, a 2000-year-old dye pigment - chemically BaCuSi206, undergoes some really cool transformations at low temperatures. It shifts from three dimensions to two. Weird.
Saying "not for kids" is, of course, the surest way you can guarantee kids wanting it. A Swiss scientist has published a review article indicating that anti-smoking laws for minors are almost totally ineffective. Surprise surprise, kids find ways around them, just as they do parents' curfews and gun-hiding techniques. The review doesn't really offer anything that shouldn't be obvious to anyone who thinks about it, but I suppose it'd be nice to think that some science could inspire some more sensible approaches to be developed.
US and Japanese researchers have found that compulsive addiction behaviors seem to stem more from aversion to withdrawal than from pleasure-seeking motives. This is, of course, obvious to anyone who's ever had a
