‘Liquid armor’ based on shear-thickening non-Newtonian fluids
Speaking broadly, non-Newtonian fluids are of two types: Either they get thinner under shear, or they get thicker. Shear-thickening fluids, like the common corn flour-water mixture sometimes called “oobleck,” obviously, get thicker when a force is applied. This new and highly secretive non-Newtonian fluid formulation by British defense giant BAE is like oobleck to the power of ten, and can, reportedly, be very effectively combined with Kevlar to improve human body armor performance against bullets.

Japanese wave-shaping machine
These are not standing waves; they appear momentarily and then recede. Which is still pretty amazing. The machine, at Japan’s National Maritime Research Institute, is being described in the English-language blogosphere as having been designed to conduct water-safety tests. [via Neatorama]
