For medicines that do not go down well in pill form, administering drugs via transdermal patches is nothing new. Patches are currently on the market for nicotine replacement, birth control, and even pain relief. But many drugs, such as an effective migraine medication called sumatriptan, do not pass easily from a patch into the skin. Drug company NuPathe has a solution: at the press of a button, an electric current running through the patch gently prods the meds into your body.

Scientists at the University of Kentucky have built tiny pipes that move water 10,000 times as fast as the conventional laws of fluid flow allow, mimicking for the first time the seamless way fluids progress through our cells. They´ve also found a way to control which molecules can pass through the pipes, a discovery that could yield safer, more efficient skin patches to deliver medicine into the body. The pipes are made of carbon nanotubes, thin sheets of graphite rolled into cylinders just seven billionths of a meter in diameter.
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.
