Do you deliberately avoid visiting friends who live in multi-story buildings without an elevator? No one would fault you -- having to climb even just a single flight of stairs is like being forced to work out against your will. But thanks to engineers at Georgia Tech and Emory University, stairs might one day do all the hard work for you.

We all know that frogs have one of nature's coolest methods of catching their prey -- blasting their tongue out and latching onto the victim. But we haven't fully understood how the process works. New research shows that frog saliva transforms in surprising ways and could be applied to making super adhesives.
All the sensors, servos and motors that allow humanoid robots like ATLAS to walk on two feet require a lot of battery power -- so much so that they're still impractical for real-world applications. But by more closely replicating a human's gait -- at least one with lots of swagger -- Georgia Tech's DURUS requires far less power.
Everyone assumes that self-driving cars will stick to the rules of the road as strictly as a teenager taking their driving test. But life is unpredictable, and often fast, evasive manoeuvres are needed to avoid an accident. To ensure they will perform just as reliably when they have to drive more aggressively, this RC truck is learning how to drift all by itself.
