IBM just got a contract to build the first petaflops supercomputer (that’s 1000 trillion computations per second). The machine will be used at Los Alamos to simulate nuclear explosions. What is really interesting is that some of the specialized processors that will be used were originally designed for the PlayStation 3.

An ancient hair dye formula, used by both the Romans and Greeks 2000 years ago (and still marketed as Grecian Formula) is based on nanoparticles, researchers say. The dye contains lead, which when applied to hair reacts with the sulfur in keratin protein to precipitate dark lead sulfide crystals. Using X-ray diffraction and other techniques they imaged the crystals. They appear to be like today’s lead sulfide quantum dots created via techniques from materials science, and are just 5 nanometers wide. Ancient Nanotech!
