Brilliant Staircase Design Stores Extra Energy to Make It Easier to Climb Later

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

Frog Tongues Finally Explained by ‘Reversible’ Saliva

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. Read More >>

Ingenious New Camera Can Read Closed Books

In a breakthrough that will appeal to both spies and those who work with priceless but frail historical documents, researchers at MIT have developed a camera that uses terahertz radiation to peer at the text on pages of a book, without it having to be open. Read More >>

Check Out This Robot’s Funky Walking Style

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. Read More >>

RC Trucks Learning to Drift at High Speeds Will Make Self-Driving Cars Safer

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 trying fast, evasive manoeuvres are needed to avoid an accident. To ensure they’ll perform just as reliably when they have to drive more aggressively, this RC truck is learning how to drift all by itself. Read More >>

Your Touchscreen Usage is So Unique it Can be Used as a Password

It turns out that your seemingly random taps, swipes, and other finger gestures on a touchscreen display might not be so random after all. In fact, the way you interact with a touchscreen is so unique that researchers at Georgia Tech have successfully created software that can lock down your tablet if someone else pokes and prods it.
