What do 3D printing, jelly, liver transplants, chainmail, dental fillings, ferrofluids, and the Six Million Dollar man have to tell us about our future? Materials scientist and engineer Mark Miodownik lets us know in this Royal Institution lecture
Defense contractor takes break from F-35 JSF, finds a way to eliminate 99% of the energy cost of desalination.
Lockheed-Martin has developed a way to craft sheets of carbon a single atom thick, which can filter the salt (and just about anything else) from water with a tiny fraction of the energy required by current processes. "Lockheed officials see other applications for Perforene as well, from dialysis in healthcare to cleaning chemicals from the water used in hydraulic fracturing, or "fracking," of oil and gas wells." Previously
Researchers at MIT and in Korea have developed
a new, efficient desalinization nanotechnology
that could theoretically lead to small, portable units
powered by solar cells or batteries, yet deliver enough potable fresh water from seawater to supply the needs of a family or small village
. As an added bonus, the system would simultaneously remove many contaminants, viruses and bacteria. MIT Press Release

Nanotech? Kids stuff.
The nanotech industry and research community has been plugging away steadily since Eric Drexler
's cheerleading for it in the early 80's. Now the National Science Foundation acknowledges (in the form of this Request for Proposals
) that kids as young as 7th grade must be prepared for living in a nanotech world.
