For wireless networks that share time-sensitive information on the fly, it's not enough to transmit data quickly: that data also needs to be fresh. Consider the many sensors in your car. While it may...

When it comes to the “smell test,” the nose isn't always the best judge of food quality. Now in a study appearing in ACS’ journal Nano Letters, scientists...

Infrared spectroscopy is the benchmark method for detecting and analyzing organic compounds. However, that requires complicated procedures and large, expensive instruments, making...

What had been a peaceful and productive mission for the six men aboard the Russian space station Mir, including U.S. astronaut Jerry Linenger, nearly became a tragic...

Stanford and Seoul National University researchers have developed an artificial sensory nerve system that can activate the twitch reflex in...

Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance...

A next-generation X-ray beamline now operating at the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) brings together a unique set of capabilities to measure the...

Optoelectronic engineers in China and Hong Kong have manufactured a special type of liquid crystal display (LCD) that is paper-thin, flexible, light, and tough. With this, a daily...

Researchers have developed an inkjet printing technique that can be used to print optical components such as waveguides. Because the printing approach can also fabricate...

The unique capabilities of soft robots are to bend, deform, stretch, twist, or squeeze in all the ways that conventional rigid robots cannot. Today, it is easy to envision a world in...

In the early years of manned flight, wing warping was used for lateral control of an aircraft. This technique consisted of a system of pulleys and cables used to twist the trailing edges of the wings in...

Resistance welding with direct current (DC) using inverter technology reduces costs by improving quality, reducing maintenance, and increasing productivity. Switching from...

Today's crop breeders are trying to boost yields while preparing plants to withstand severe weather and changing climates. To succeed, they must locate the genes for high-yielding, hardy traits in crop...

There are applications that require multiple electric machine drives, such as electric or hybrid electric vehicles, where there is a main traction motor and one or more accessory...

Researchers at NASA's Marshall Space Flight Center have devised a method for the creation of crystal-free non-oxide optical fiber preforms. Non-oxide fiber optics are extensively used in...

Marine-grade stainless steel is valued for its performance under corrosive environments, and for its high ductility — the ability to bend without breaking under stress. But conventional...

When Navy SEALs carry out dives in Arctic waters, or when rescue teams are diving under ice-covered rivers or ponds, the survival time even in the best wetsuits is very limited — as...

Currently, concussion is measured by the symptoms someone experiences, but it is difficult to know what is happening in the brain in any one person. To address this problem, a portable brain imaging system was...

Lithium-metal batteries — which can hold up to ten times more charge than lithium-ion batteries — haven't been commercialized because of a fatal flaw: as the batteries charge and...

The most common methods for glucose self-testing involve monitoring glucose levels in blood. These conventional measurements are not suitable for preventing hypoglycemia during exercise. The...

Silver nanowires have drawn significant interest in recent years for use in many applications ranging from prosthetic devices to wearable health sensors due to their flexibility,...
