  • Scientists develop the world's smallest single-molecule electric motor

    Bigger is certainly not better when it comes to the world's first single-molecule electric engine, which measures in at one nanometer wide -- for perspective, that lash hanging from your left eye is around 60,000 times larger. Single-molecule engines have been used for years, but the new method uses a low-temperature scanning tunneling microscope to power and control the molecule more effectively. In the future, scientists could use the technology for things like lab-on-a-chip devices, miniature medical testing equipment that require a motor to push fluid through tiny pipes. Tufts researchers responsible for the discovery warn that a practical application is still a ways off, but are hopeful that they'll snag a Guinness world record, regardless. After hearing the news, both Pinky and The Brain are feeling entirely more confident about their lifelong goals.

  • Researchers build a robot inspired by caterpillars, nightmares (video)

    There's a long history of robots modeled on animals, and some researchers from Tufts University have now taken things in a particularly creepy-crawly direction. They've built a robot that's able to mimic the way a caterpillar balls itself up to bounce away from predators. As you can see in the video above, while the robot (dubbed GoQBot) is quite a bit bigger than the actual bug, is does indeed do a pretty good caterpillar imitation. What might such a bot be used for? Well, the researchers say that the so-called "ballistic rolling" behavior could be used to improve on some of the many existing robots that are modeled on worms or snakes -- which could let them fling themselves into a disaster area, for instance, and then wiggle around to aid in search and rescue operations. Head on past the break to see the bot in slow-motion.
