"Your carbon is our lifeblood! Your matter is our market! Your DNA is all we need!"
Whoever wrote up the event for the San Diego Union-Tribune seems as baffled as I am, noting that "It isn't entirely clear what the health effects are of the strangely-named nanoparticles (like carbon buckyballs or halogenated phenoxy)."
Read about what our future with nanotechnology and capitalism will be like in Todd Seavey's "Neither Gods Nor Goo." (Hint: no apocalypse, lots of stain resistant pants.)
