It has been known since the early 1960s that hexagonal sampling is the optimal sampling approach for isotropically band-limited images, providing a 13.4% improvement in sampling efficiency over...

Until about 20 years ago, scientists relied on chemical fluorescent dyes to make biological molecules visible. To look inside cells, stain organelles, and perform...

Following severe trauma, patients may have tissue damage or open wounds that require reconstructive surgery using fasciocutaneous flaps. These flaps of tissue, which are taken from...

Accurately measuring semiconductor properties of materials in small volumes helps engineers determine the range of applications for which these materials may be suitable in the...

A robot is being developed that tracks facial movements to perform human tasks. The robot resembles large, squiggly arms holding tiny cameras. Sitting in a rolling office chair across from one of the arms, the robot's...

There's an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can't see. But infrared cameras can pick up this light emitted as...

With the aim of bringing more human-like reasoning to autonomous vehicles, MIT researchers have created a system that uses only simple maps and visual data to enable driverless cars...

Scientists at the University of Sheffield have been working with HiPERCAM, a high-speed, multicolor camera, which is capable of taking more than 1,000 images per...

By capping liquids with graphene (an ultrathin sheet of pure carbon), researchers can easily image and analyze liquid interfaces and the surface of nanometer-scale objects...

Experimental photonic switches developed at UC Berkeley have shown promise toward the goal of fully optical, high-capacity switching for...

A new learning system improves a robot’s ability to mold materials into target shapes and make predictions about interacting with solid objects and liquids. The system, known as a...

Graphene Flagship partner ICFO, based in Barcelona, Spain is developing graphene-based prototypes that aim to turn mobile phones into life saving devices. The first of these will allow...

An ingestible pill was developed that, upon reaching the stomach, quickly swells to the size of a soft, squishy ping-pong ball big enough to stay in the stomach for an...

Researchers at NASA’s Johnson Space Center improved their Flash Thermography capabilities by incorporating transient and lock-in thermography. By...

Simon Fraser University and Swiss researchers are developing an eco-friendly, 3D printable solution for producing wireless Internet-of-Things (IoT) sensors that can be...

Researchers have created stretchable, rubbery semiconductors including rubbery integrated electronics, logic circuits, and arrayed sensory skins fully based on rubber materials. The semiconductors have...

Stretchable electronics, which can be stretched, deformed and wrapped onto nonplanar curved surfaces, have attracted much attraction due to their...

Light is widely used for communications, carrying phone conversations and video signals through fiber optic cables around the world in pulses composed of many photons. Single...

Microwave signals are ubiquitous in wireless communications but interact too weakly with photons. A technique was developed to fabricate high-performance optical microstructures using lithium niobate, a material...
