We use a lot of energy to ship goods, but it's not always very efficient. With pasta, for example, most of what we're shipping is the air in the box. So a team at Carnegie Mellon University found a way to make flat-packed pasta that changes shape as it cooks. Plus: the New York Times briefly published a story that claimed "Fields of Watermelon Found on Mars, Police Say." It was almost certainly a test page, but still, maybe the Mars rover should do a quick check.
