When disaster strikes, drones and robots can be sent into danger zones to scout for survivors. The RoBoa from a student team at ETH Zurich is designed to snake its way through debris that would stop other solutions in their tracks.

Ice wreaks havoc on surfaces, but we might have a new way to prevent it building up. Scientists at Northwestern University have shown that textured surfaces with thin layers of graphene oxide can stay completely frost-free for long periods.

Mahle has been hard at work on next-gen e-drive systems, and it's also been exploring other electrification components. It has revealed a thermal management fan that borrows from nature to provide smoother, quieter, more efficient performance.

Pangolins already dig in the dirt, so why not get them planting trees while they're at it? Well, training them would be pretty hard, which is why a California high school student named Dorothy designed a pangolin-inspired robot to do the planting.

Tubular structures that fold flat for storage may not take up much room in that form, but they also tend not to be very strong when deployed. That isn't a problem with an experimental new type of tube, that's inspired by both origami and bamboo.

Ordinarily, if you want liquid to flow in only one direction through a pipe, that pipe has to have a flap-type valve – which could fail. Now, scientists have created a new type of more robust one-way-flow pipe, which was inspired by shark intestines.

Sensors such as EEG electrodes can help save a person's life, but the adhesive patches used to attach them may also harm that person's skin. An experimental new medical patch addresses that issue by utilizing octopus-inspired suckers.

Soft materials and stiff materials both have their uses, but the two properties typically aren't seen in one substance. RoboFabric is an exception, then, in that it can be switched back and forth between soft and stiff states.

Tiny aerial drones have many potential uses, but their ability to navigate is severely limited by their minuscule amount of onboard processing power. Scientists have now set about addressing that limitation, taking a cue from foraging insects such as ants.

Multirotor drones may get all the glory, but fully rotating "monocopters" are much more energy-efficient. A new one distinguishes itself further, as it can squeeze through narrow spaces or drop like a falcon by reducing its wingspan while in flight.

Scientists have created a four-legged bio-inspired robot that climbs like no other. It clings to rough vertical surfaces utilizing a unique mechanism that is highly effective, yet at the same time relatively simple.

Scientists have replicated the seed-delivery system used by wild oats, resulting in a seed-carrying bio-hybrid "robot." Scores of the tiny devices could one day be utilized for much easier, more effective aerial seeding of crops or even new forests.
