How do you feel? Video of your face may tell all
Rice University researchers are developing a highly accurate, touch-free system that uses a video camera to monitor patients' vital signs just by looking at their faces. The technique isn't new, but engineering ...
Knowing whether food has spoiled without even opening the container (w/ video)
A color-coded smart tag could tell consumers whether a carton of milk has turned sour or a can of green beans has spoiled without opening the containers, according to researchers. The tag, which would appear ...
New analysis yields improvements in a classic 3D imaging technique
Research conducted at Curtin University in Perth has enabled significant increases in image quality in a widely used 3D printing technique that is more than 100 years old.
Birds of a different color: Three major genes set feather hue in pigeons
Scientists at the University of Utah identified mutations in three key genes that determine feather color in domestic rock pigeons. The same genes control pigmentation of human skin.
Look, something shiny! How color images can influence consumers
When it comes to buying things, our brains can't see the big, black-and-white forest for all the tiny, colorful trees.
Building a better light bulb
Scientists study the movement of charge carriers to design an organic LED that is energy efficient and still casts a warm, natural glow.
Biomimetic photodetector 'sees' in color
(Phys.org) —Rice University researchers have created a CMOS-compatible, biomimetic color photodetector that directly responds to red, green and blue light in much the same way the human eye does.
Color printing at highest resolution possible enabled by use of arrays of metal-coated nanostructures
Commercial laser printers typically produce pin-sharp images with spots of ink about 20 micrometers apart, resulting in a resolution of 1,200 dots per inch (dpi). By shrinking the separation to just 250 nanometers—roughly ...
Fine-tuning a rainbow of colors at the nanoscale
(Phys.org) —TVs, image sensors, iPads, digital cameras and other modern devices use filters to display the breadth of colors available in the visible portion of the electromagnetic spectrum.
Color-tunable photonic fibers mimic the fruit of the 'bastard hogberry' plant
(Phys.org)—A team of materials scientists at Harvard University and the University of Exeter, UK, have invented a new fiber that changes color when stretched. Inspired by nature, the researchers identified ...
African starlings: Dashing darlings of the bird world in more ways than one
It's not going to happen while you're peering through your binoculars, but African glossy starlings change color more than 10 times faster than their ancestors and even their modern relatives, according to ...
iPad dominates due to Apple's supply deals
Apple certainly has lots of buzz and corporate cache behind its products, but there's a hidden - almost mundane - reason its newest iPad is likely to dominate the competition: the advantageous deals the company ...
Electrochromic polymers create broad color palette for sunglasses, windows
Artists, print designers and interior decorators have long had access to a broad palette of paint and ink colors for their work. Now, researchers have created a broad color palette of electrochromic polymers, ...
