​We hear a lot about aerial and underwater drones, but ones that travel on the water's surface … not so much. They can be quite useful, though, as we discovered when we recently checked out the Heron USV (unmanned surface vessel) at the International Conference on Robotics and Automation.

​Vertical Take-Off and Landing (VTOL) drones typically have four horizontal propellers for moving up and down, along with a vertical rear "pusher" prop for moving forward in more efficient fixed-wing flight. A new aircraft, however, uses the same four props for everything.

​Back in 2013, we heard about an all-terrain walking robot known as RHex. Designed in a collaboration between McGill University and the University of Pennsylvania, it used six flipper-like legs to scamper around. Now, its successor is taking to the briny depths.

At the SMMT off-road test day at Millbrook Proving Ground in Bedfordshire, UK, Team Dynamics Motorsport and Ralph Hosier Engineering each debuted a Honda Civic Type R concept. These Civics are meant to show what is possible with the car as a basis for a rally machine.

For thousand of years humans have been using fermentation as a way of preserving foods and engendering good gut health. A new study has discovered that a specific immune function receptor, evolved in humans and apes, is triggered by a metabolite from lactic acid bacteria found in fermented foods.

Using the latest trend in artificial intelligence – adversarial learning – Samsung has demonstrated that it can take a single image of a person and turn it into a talking head. And if watching the Mona Lisa come to life doesn't send chills down your spine, you need to check your pulse.

Two remarkable new studies are suggesting sci-fi stories of memory manipulation may not be so far-fetched. The research describes early proof-of-concept experiments showing how negative emotional associations with traumatic memories can potentially be weakened or even entirely edited out.

Carlo Ratti Associati (CRA) is planning to bring something of the Italian countryside to inner-city Milan with its Vitae project. The eye-catching building will host research facilities, offices and a restaurant, and will be covered in greenery, including a vineyard.

Dutch design firm Studio Rotor has been working with startup Retter Helfer Medical on a lightweight patient transport option for ambulance personnel. The Multi Scoop Pro features a patented mechanism that sees it change from flat stretcher to wheelchair in a matter of seconds.

Last time we wrote about the HyQ robot​, it had just mastered walking and begun venturing into rough terrain. Now, its successor has do so with a three-ton passenger airplane in tow.

​Remember those "bottle"-type dynamos that rubbed against the side of your bike tire in order to power the lights? Well, they've gotten a high-tech makeover, in the form of the CadenceX generator – its creators say that it can replace the batteries currently needed for all bicycle electronics.

​3D printing technology is set to have a real impact on the worlds of building and construction. Adding to the mix of possibilities is a new proof-of-concept bathroom unit, which scientists in Singapore were able to 3D print in its entirety in a single day.
