Thought for the month
“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”
Margaret Thatcher, 1 October 1996.

Paint it black
I doubt that Mick Jagger will ever sing about carbon nanotubes. However NASA have devised a coating based on multiwalled carbon nanotubes that is about 10 times better at absorbing light, and thus suppressing stray light, than the black paint (NASA Z306) typically used by their instrument engineers. NASA has many observational and measurement related activities where background illumination is the ultimate resolution determinant and so require a paint that is blacker than black.
