Soot was just so ordinary no one ever bothered to distill the different molecules out of it, to see if any had unusual properties. C60 is just too big a fraction, with too distinct properties, to have been missed otherwise for so long.

There are literally thousands of different species produced when even the simplest organic compound is burned incompletely (i.e., to form soot). C60 is a tiny fraction of what's produced in most soot from ordinary flames. This is why C60 is still $50 a gram. It actually took the researchers who found C60 in candle soot a pretty heroic effort, and even then, they already knew what they were looking for. The manufacture of C60 on an industrial scale occurs by maintaining an electrical arc across two graphite rods in a rarefied atmosphere. The temperature of the carbon plasma created is around 10000-15000 K, as opposed to a candle flame, which usually isn't more than a few thousand Kelvin. The exciting thing about this study is that there have been several groups that have proposed areas in space where these kinds of high temperature, low pressure conditions exist (namely in the atmospheres of aging red giants) which should, with the carbon rich atmospheres of these stars, form detectable amounts of fullerenes. Until now, this was just a theory. Obviously, it's still just a theory, but at least now it has some evidence to back it up.

World's Smallest Superconductor Discovered 72

arcticstoat writes "One of the barriers to the development of nanoscale electronics has potentially been eliminated, as scientists have discovered the world's smallest superconductor. Made up of four pairs of molecules, and measuring just 0.87nm, the superconductor could potentially be used as a nanoscale interconnect in electronic devices, but without the heat and power dissipation problems associated with standard metal conductors."

This brings up an interesting point. If we can use gene therapy to cure colorblindness or extend our senses, couldn't we also use it to give us certain disabilities to take advantage of handicapped laws? Or maybe we could change out our skin colors like the cool kids do with their ringtones. Or perhaps we could customize our abilities like we do our computers. Some of us may want a bare-bones system (literally?) or to be stripped of stuff we don't really need (like a complete vas deferns or Fallopian tube until we're ready to reproduce). I've seen a few commenters talking about a slippery slope, but what if you want to go skiing for a while (just to completely milk that metaphor)?
