The shorter a drone's propellers, the less efficient they are at keeping it airborne. That factor, along with compact, low-capacity batteries, is the reason that small drones can't fly very long. A new two-prop drone, however, is claimed to deliver twice the flight time as same-sized quadcopters.

We've seen robots that can walk, trot, run, and even do backflips, but now a student team is working on a rover robot prototype that is designed to travel in lunar gravity by controlled bounds into space where all four legs leave the ground.

While shape-memory materials do have some interesting applications, many of them require the application of heat in order to change shape – and that could cause problems, in environments such as the human body. A new material, however, relies instead on a magnetically-responsive liquid.

Researchers in Switzerland have figured out a way to reduce the temperature of water to a very cool -263° C (-441.4° F) without freezing it, opening up some interesting possibilities around how we study molecular structures at extreme temperatures.

Scientists have created the first fully computer-generated genome of a living organism. Named Caulobacter ethensis-2.0, it was built by simplifying the natural code of Caulobacter crescentus. The team says this is a huge step towards creating completely synthetic life and medicinal DNA molecules.

Goggles, glasses and windshield can fog up if there’s a difference in temperature or humidity. Researchers at ETH Zurich have developed a new anti-fog coating that warms up the surface without needing electricity.

Chemotherapy drugs are effective at killing cancer cells – but they’re also pretty good at killing healthy cells. Making these drugs more selective for tumors is a key area of research, and now a team at ETH Zurich has found a way to keep a common treatment – platinum nanoparticles – on target.

The human body is full of wildly different environments, so any robots exploring them need to be able to adapt on the fly. Now, researchers at EPFL and ETH Zurich have developed micro-robots that can automatically morph in response to their surroundings.

Mother of pearl is the coating found on the outside of pearls, and the inside of certain mollusc’s shells. It's one of nature's hardest, stiffest, most stable materials – and scientists have now figured out how to make an artificial version of it, which can be "tuned" for different applications.

In motion-capture animation, an actor moves through a studio equipped with multiple cameras. A computer tracks markers on their body, building a 3D "skeleton" that is used to create the final animated character. Experimental new drone-based tech, however, may make the process much easier.
