This water harvester could extract drinkable water even from dry air

Researchers have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat...

Scientists print wearable sensors directly on skin without heat

Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international...

New circuit could generate clean, limitless power from graphene

A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical...

Marine sponges inspire the next generation of skyscrapers and bridges

When we think about sponges, we tend to think of something soft and squishy. But researchers at Harvard University are using the glassy skeletons of...

Scientists use AI to optimize vanadium flow battery performance and cost

Vanadium flow batteries (VFBs) are promising for stationary large-scale energy storage due to their high safety, long cycle life, and high efficiency. The cost of...

This novel fisheye lens is completely flat

The single piece of glass produces crisp panoramic images. To capture panoramic views in a single shot, photographers typically use fisheye lenses — ultra-wide-angle lenses...

Scientists create better material for wearable biosensors

Biosensors that are wearable on human skin or safely used inside the body are increasingly prevalent for both medical applications and everyday health monitoring. Finding...

New way to predict the slow death of lithium-ion batteries

The new tech could improve driving range estimates and prolong battery life. Batteries fade as they age, slowly losing power and storage capacity. As in people,...

Scientists find a better way to detect prediabetes

In a new study, researchers have developed a patch of needles connected to a paper sensor for diagnosing conditions such as prediabetes. Luckily, this patch...

New photon device offers ‘x-ray vision’ through fog

Using a new algorithm, researchers have reconstructed the movements of individual particles of light to see through clouds, fog, and other obstructions. It’s like a...
