Our friends at io9 have a great little overview of what we scientific types like to call the Eternal Sunshine Molecules (note: no scientific types call them that.). These are the recently-discovered molecules that may be able to erase, restore, retain, and protect our memories--at least, they might, in the coming decades.
Check out io9's feature for more on molecules like CaMKII, which leads to the inability to recall short-term memories associated with fear. (Curious about the moral side of that? Check out this ethicist's position.)
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
