Orbiting satellites are mostly propelled by gravity. But electrospray propulsion is sometimes used to reposition them. The fine nozzles in such systems are notoriously prone to breakage though, so researchers developed a way to create them out of their own fuel source, making them self-healing.

A team of engineers at MIT is working on a smaller computer chip that can be installed in a drone the size of a bottle cap, yet can take images and navigate the device with a minimum of power.

​An international team of astronomers has discovered the smallest ever star to date – a tiny red dwarf only slightly larger than the planet Saturn. Known as EBLM J0555-57Ab, it sits roughly 600 light years from Earth, and was found using a technique ordinarily used for hunting exoplanets.

​​When Airdog arrived on the scene in 2014, it was one of the first drones to offer auto-tracking technology, commonly known as follow-me mode. A suite of competitors have since worked this feature into models of their own, and the team at Airdog seems intent on playing to its strengths.

A few days ago, the Juno probe completed the closest flyby of Jupiter's infamous Great Red Spot ever conducted by a spacecraft. After an agonizing wait the photos are now in… and they are absolutely incredible.

Climbing stairs is a chore that's inspired some creative alternatives. Now a team from Georgia Tech and Emory University has developed energy-recycling stairs that take some of the pressure off the knees and ankles, by storing energy from people descending then giving it back as they climb up.

​Scientists have been experimenting for some years with electroencephalography (EEG) as an interface for mind-controlled devices. Now a group of researchers has developed the Encephalophone, a musical instrument that can be played using the power of your mind.

There’s a mind-boggling amount of data naturally stored in the genome of every organism, with far better density and durability. Now a Harvard team has created a biological hard drive, using the CRISPR gene-editing tool to record information to (and retrieve it from) the genome of living bacteria.

Most people don’t understand sign language, to the frustration of those who rely on it to communicate. Now engineers have developed a prototype called “The Language of Glove,” a Bluetooth-enabled, sensor-packed glove that reads the hand gestures of sign language and translates them into text.

​While still not as plentiful as their aerial cousins, there are now several underwater drones that are either in development or production. And while almost all of the ones that we've seen so far can't go deeper than 100 m (328 ft), the new Blueye Pioneer can go down to 150 m (492 ft).

​Dodge set the internet alight with the Demon earlier this year, but it's been busy on other projects as well. It doesn't get the full gamut of drag features from the Demon, but the new Hellcat Widebody borrows from its unhinged big brother to deliver more grip and a meaner, more imposing stance.

Online supermarket Ocado in the closing stages of a grocery delivery trial, where customers get their shopping delivered by a self-driving electric CargoPod. Developed by Oxbotica for the experiment, the vehicle uses sensors and software to make its way around without the need for GPS.
