It goes without saying that if someone has a blood clot in their brain, that clot should be cleared as soon as possible. An experimental new transducer could help, as it uses swirling waves of ultrasound to break up blood clots much faster than existing methods.

A new technique using piezoelectric nanoparticles that are activated via bursts of ultrasound has shown promise as a wire-free way to stimulate the brain. It could be used to treat Parkinson's disease and other brain-based disorders.

When it comes to communicable diseases, it's important to identify the source of an outbreak ASAP. In the case of cholera, a new toilet sensor could help, by detecting how many people in one area are experiencing one of the main symptoms – diarrhea.

Stents can make a life-saving difference for people with vascular problems, as they open up narrowing blood vessels. An experimental new one goes a step further, by actually transmitting blood flow data to an external computer or mobile device.

Although there are various systems that detect quadriplegics' head movements, most such setups are limited to the control of wheelchairs. Such is not the case, however, with the MagTrack system.

Although electroporation technology is very effective at delivering DNA-based vaccines, the required equipment is bulky, complex and expensive. Now, however, scientists have shown that a converted barbecue lighter is capable of doing the job.

While aerial drones do show promise as a means of urban parcel delivery, their small size will limit them to carrying relatively light packages. An experimental new system, however, lets multiple drones team up to hoist heftier items.

The excavation and disposal of landmines is a time- and labor-intensive business, so it can be quite a waste of resources if the detected object is not actually a mine. A new system could help, by reducing the number of mine-hunting errors.

A tiny new sensor that can be worn in items of clothing could offer a new way to tap into the subtle vibrations produced by a wearer's heart and lungs, and even alert the user when it might be time to head for a checkup.

​We've already heard about gloves and cameras that could be used to translate hand gestures (such as American Sign Language) into text or spoken words. What might be simpler, though, is a system consisting of just a ring and a wristband – which has been created.

Scientists have developed an AI system that can recreate a video game engine after watching just two minutes of gameplay, which could help lighten the load for developers and allow them to experiment with different styles of play.

​Like pretty much any other computer-controlled device, 3D printers can be maliciously hacked. That's why scientists have developed a new system for making sure that the machines are doing what they're supposed to.
