Although aerial drones can travel much faster than their underwater counterparts, they certainly aren't as good at gathering water-related data. The MEDUSA multi-rotor drone addresses this conundrum, by landing on the water and deploying an underwater pod.
-
While we have heard of a few aerial drones that are also able to operate underwater, a new one takes that concept considerably further. Using a fish-inspired suction disc, it can hitch rides underwater – possibly even on submarines – to save power.

While antibiotics are very effective at treating infected wounds, they should definitely be used sparingly. An experimental new bandage was designed with this fact in mind, as it only dispenses medication when it detects the heat of an infection.

As 3D-printed electrical circuits become more widely produced, the problem of electronic waste could correspondingly get worse. That's why Swiss scientists have developed a new natural-source "e-ink" that biodegrades once discarded.

The construction industry is a big producer of CO2, and ETH Zurich has been working on new techniques that help clean up the industry's act. The result is the HiLo, which was built using minimal concrete and has impressive sustainability features.

Scientists in Switzerland have been working to bring the efficiency of CIGS flexible solar cells up to the levels offered by rigid solar cells, and have taken another step toward this goal by setting a new record of 21.4 percent.

When it comes to closing incisions or other wounds in the digestive tract, sutures alone aren't enough to keep fluids or food waste from leaking out into the abdomen. A new hydrogel patch is designed to help, by thoroughly sealing such injuries up.
-
Although optical fibers are highly effective at data transmission, they're also relatively brittle. An experimental new type of optical fiber addresses that limitation, by incorporating a core made of liquid glycerol.

In many countries, long, dark winters limit the amount of solar energy that can be generated for much of the year. That's where the Underground Sun Conversion system comes in, as it's intended to use sunlight to help produce natural gas underground.
-
As technology continues to evolve, we're going to see an increasing number of battery-powered connected devices – some of which will be single-use, like shipping packaging. A new biodegradable mini-capacitor has been created with such uses in mind.
-
Researchers have demonstrated how patterns of string carefully laid out by robotic arms can be used to bind asphalt together in place of environmentally damaging bitumen, resulting in greener roads that are also easier to recycle after use.

In order for a thief to bypass a security system's interface, they generally have to see that interface in the first place. That's why Swiss scientists have designed an access code keypad which is completely transparent.
