Lasers have revolutionized the world in many ways -- they allow everything from satellite communication to precision-cut diamond -- but even so, they were supposed to be so much more. From missile ...

Jerusalem, Israel] While nanocrystals offer color tunability and are used in various technologies, achieving different colors requires using different nanocrystals for each color, and dynamic ...

Rewritable smart materials and colour switching technologies represent a burgeoning field at the interface of chemistry, materials science and engineering. These systems offer a sustainable ...

Researchers have developed a fluorescent small molecule that attaches to biomolecules through azide−alkyne cycloaddition—a click reaction—and converts from green to red with the flash of a laser. The ...

When Martin Scorsese decided to include old-fashioned movie-house newsreels in his new film, “Killers of the Flower Moon” (Apple TV+), he and cinematographer Rodrigo Prieto knew they’d be shot in ...

Fabrics that change color on demand could help soldiers blend into their environments and could enable wearable displays and sensors. In a step toward such textiles, researchers have made flexible ...

Illustration of the pump color-controlled metadevice for coded terahertz switching. a, Measured THz transmission spectral variation at various coded states. b-f, Pumping color driving THz spectral ...

As long-time readers may recall, I've long held an intense interest in analog- and digital-domain video processing. Look, for example, at this hands-on project from June 2001 (how time flies) that ...

Fast user switching (accessible from Login Options in the Accounts System Preference pane) makes it easy to keep two or more users logged in to a Mac at the same time. Instead of logging in and out ...

New research has achieved a significant breakthrough in color switching for nanocrystals, unlocking exciting possibilities for a simple, energy efficient display design and for tunable light sources ...

No fewer than five awards season movies — including 'Oppenheimer,' 'Killers of the Flower Moon,' 'Poor Things,' 'Maestro' and 'The Color Purple' — alternate between black and white and color.
