People at University of Tokyo created a 5-millimeter tall living doll out of living cells.
It reportedly lived for more than a day in a culture solution. The goal of the project seems to be to be able to build human tissue and organs from scratch. But what a way to start!
What would happen if you threw a boomerang in a microgravity environment (like, say, if you were in the International Space Station)? Well, now thanks to astronaut Takao Doi, we have the answer, and it is completely awexome:
ApriPoko, this unbearably cute remote control from (where else) Japan can tell when you're using another remote control, and actually asks you what you just did. You tell it (for example, "I turned up the volume on the TV"), and it records the infared signal that the other remote sent out. Then if you later tell ApriPoko, "Turn up the volume on the TV," it emits that exact same infrared signal to the TV!
