MIT chemists have printed carbon nanotubes on paper to create a sensor for detecting dangerous gases. The lines are printed on specially treated paper. When an electrical current is passed through the paper, the change in resistance indicates gas molecules that have bound to the printed nanotubes. The test sensor detected small traces of ammonia…

In this video, Japanese astronaut, Dr. Takao Doi, throws a boomerang inside the International Space Station, in a zero-G environment. Before the experiment, they really were not sure what it would do, thinking it would probably spin up and away from the thrower, As it turns out, it acts pretty much the same as it…
