Our favorite grippy robot fist, the balloon filled with coffee grounds, has graduated from grabbing to throwing. Its developers at Cornell University and the University of Chicago have taught it how to hurl objects, from mini basketballs to darts.
OK, so it can’t reach the energies produced at the LHC or Tevatron, but this is still pretty impressive. Engineers at a micro-electro mechanical systems conference last week unveiled this tiny cyclotron device, which can speed argon ions down a 5-millimeter accelerator track.
Slow and steady really does win the race. A diminutive robot perched atop stork-like legs has slowly strode beyond BigDog’s world record for robotic walking, making a continuous 11-hour trek around an indoor running track at Cornell University that covered 14.3 miles.
Leaping tall buildings, punching through solid concrete walls and using public phone booths as ersatz changing rooms without anyone noticing are still beyond human capacity, but a development at Cornell University might allow us to walk on walls like Spider Man, or even dance on the ceiling like Lionel Richie.
New York is the most photographed city in the world. The Eiffel Tower is the most photographed landmark. And in what may be a sign of the times, the Apple retail store in midtown Manhattan is the 28th-most-photographed place in the world.
Will we grow babies outside their mothers' bodies?

A fetus lives in a world of bubbles. In its earliest days, it’s shaped like one. Later, it floats in one-the squishy, enveloping amniotic sac. And eventually, if all goes well, the fetus releases one bubble of fluid, then another and another, like smoke signals, as it puckers and swallows and floats in the womb. It was the bubbles that first convinced Hung-Ching Liu two years ago that a baby might actually be grown outside its mother’s uterus.
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.
