Researchers develop method to create colloidal diamonds

The colloidal diamond has been a dream of researchers since the 1990s. These structures—stable, self-assembled formations of miniscule materials—have the potential to make light waves as useful as electrons in computing, ...

Scientists solve mystery of glassy water

Water has some amazing properties. It is the only natural substance found in all three states — solid, liquid and gas — within the range of natural Earth temperatures. Its solid form is less dense than its liquid form, ...

Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Physicists solve mysteries of microtubule movers

Active matter is any collection of materials or systems composed of individual units that can move on their own, thanks to self-propulsion or autonomous motion. They can be of any size—think clouds of bacteria in a petri ...

Brown engineers build a better battery -- with plastic

Brown University engineers have created a new battery that uses plastic, not metal, to conduct electrical current. The hybrid device marries the power of a capacitor with the storage capacity of a battery. A description of ...

Scientists present a new method for imaging individual electrons

Imagine going for an MRI scan of your knee. This scan measures the density of water molecules present in your knee, at a resolution of about one cubic millimeter—which is great for determining whether, for example, a meniscus ...
