1) Treasure Caves A Day Out: Paleoanthropology
A trip report describing the public access to the Cradle of Humankind World Heritage site, and specifically a trip to the Sterkfontein caves in South Africa, the location of past and active digs for Australopithecus remains. The author takes her 9-year old son along for the trip. http://www.sciencemag.org/content/335/6064/40.1.full.pdf 2) Candle Soot as a Template for a Transparent Robust Superamphiphobic Coating A very cool scientific paper outlining the construction of a "superamphiphobic" coating--a coating that repels both water and hydrophobic solvents. Essentially the authors use a layer of candle soot to create a rough, fractal surface on glass that is used as the undersurface for a more permanent silica surface (deposited by vapor diffusion). The underlying candle soot is then "baked off" and the new, thin surface is transparent in the visible range (as long as it remains a relatively thin layer). Supplemental info and movies make this a fascinating article, and help explain the physics and engineering behind the recently described Liquipel coating in a post by Mark Minton http://www.sciencemag.org/content/335/6064/67.full.pdf As always, if you are unable to access this content, drop me an email message and I'll forward it to you.
