Using a paper clip and a single match to defuse a bomb and escape through a two foot square hole? Not exactly, but here are ten real-life situations where people were very resourceful.
Researchers from North Carolina State University have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.

A mystery announcement from NASA is coming Monday, which will (we think) publicize the confirmation of flowing water on the surface of Mars. It’s kind of a big deal that a massive ocean could be sitting there flowing under the red surface, mostly because where there’s water, there’s the potential for life. Here’s how we got to this point.
Astronomy fans, you don't even need a telescope for this one. On September 27, sky gazers will see the Moon at its perigee (closest point of orbit) plus a full moon, plus a total lunar eclipse. It will appear 14% larger than usual and also have a reddish tinge to it.
If you miss this one, there won't be another until 2033.

SpaceX's Dragon capsule has proven itself over and over during cargo deliveries to the International Space Station, but the version of the craft made to carry humans has yet to do so — although if it works anywhere as well as it looks in these newly published photos, it should be fine.

You may not think of plants as particularly chatty or active organisms, but they're not as passive as they might seem. Plants can't run away, so they have to develop other strategies to stay alive, as James Cahill, an environmental plant ecologist at the University of Alberta, explains in "What Plants Talk About," a documentary from the PBS show NATURE. They've evolved the use of chemicals to communicate with insects and each other in order to thrive. Here are five behaviors that show how active plants can be.
