Although we do keep hearing about flexible wearable electronics, most such devices are still powered by rigid batteries that regularly need to be recharged. An experimental new battery, however, is soft, stretchable, and powered by human sweat.

A new example of a material with shape-shifting capabilities is modeled on ancient chain mail armor, enabling it to swiftly switch from flexible to stiff thanks to carefully arranged interlocking particles.

Bike helmets work by absorbing impact energy that would otherwise be passed through to the wearer's head. An experimental new helmet is claimed to do so better than conventional models, thanks to a special resin.

Along with their batteries, many electric cars now utilize supercapacitors for tasks such as quickly delivering power while accelerating. Thanks to new research, a key component of such devices could soon be made from waste tamarind shells.

Most earthquakes last seconds to minutes, but others rumble along slowly for weeks or months, at low frequencies that may not be felt at the surface. Now researchers in Singapore have discovered the slowest earthquake ever found, lasting 32 years.

The people of Singapore consume a lot of fish, and – perhaps surprisingly to some of us – a lot of frog meat. Scientists have now developed a method of converting the waste from both foods into a material that helps bone to regrow.

Back in 2015, we heard about an electrically activated glue that could be used to bond items in wet conditions, or even underwater. Now, scientists have demonstrated that the material could be used to patch leaky blood vessels … from the inside.

Last year, we heard how scientists had created eco-friendly soft gel particles from hard grains of pollen. Now, they've used those particles to create sponges that could soak up oil spills, then biodegrade once used up.

If you worked in a dingy, windowless environment, it would be nice (and energy-efficient) if you could get natural daylight "piped in" from outside. An experimental device does exactly that, in a new compact and robust form.

Although not a huge seller everywhere, durian fruit is consumed in great quantities in countries like Singapore. Scientists there have now developed a method of using its husks to create cheap, eco-friendly, antibacterial hydrogel bandages.

Plants are complex organisms that use electrical signals to sense and respond to their surroundings. New research shows how this might enable them to be used to pick up fragile objects, among other interesting possibilities.

When someone has a skin condition such as eczema, it helps to be able to see all of the tiny ridges and grooves in the affected area. That's where a portable new device comes in, which is designed to produce 3D images of skin in a matter of minutes.
