Cornell researchers are taking 3-D printing and 3-D modeling to a new level by using augmented reality (AR) to allow designers to design in physical space while a robotic arm rapidly prints the work. “Instead of designing 3-D models on the computer screen, we wanted to give users the opportunity to work in conjunction with

When they turn up in family pantries or restaurant kitchens, cockroaches are commonly despised as ugly, unhealthy pests and are quickly killed. But in the name of science, Johns Hopkins researchers have put these unwanted bugs to work. In a crowded, windowless lab, scholars and students are coaxing the insects to share some crucial locomotion

New research has demonstrated how the nano-architecture of a silkworm’s fiber causes “Anderson localization of light,” a discovery that could lead to various innovations and a better understanding of light transport and heat transfer. The discovery also could help create synthetic materials and structures that realize the phenomenon, named after Nobel laureate Philip Anderson, whose

Using a new technique they call ‘in-air microfluidics’, University of Twente scientists succeed in printing 3D structures with living cells. This special technique enable the fast and ‘in-flight’ production of micro building blocks that are viable and can be used for repairing damaged tissue, for example. Microfluidics is all about manipulating tiny drops of fluid

The rapid development of flexible and wearable electronics is giving rise to an exciting range of applications, from smart watches and flexible displays–such as smart phones, tablets, and TV–to smart fabrics, smart glass, transdermal patches, sensors, and more. With this rise, demand has increased for high-performance flexible batteries. Up to now, however, researchers have had

3-D printing has come a long way since the first “rapid prototyping” patent was rejected in 1980. We’ve evolved from basic designs to a wide range of highly-customizable objects. Still, there’s a big issue: once objects are printed, they’re final. If you need a change, you’ll need a reprint. But imagine if that weren’t the

Accurately measuring electric fields is important in a variety of applications, such as weather forecasting, process control on industrial machinery, or ensuring the safety of people working on high-voltage power lines. Yet from a technological perspective, this is no easy task. In a break from the design principle that has been followed by all other

Fuel cells have the potential to be a clean and efficient way to run cars, computers, and power stations, but the cost of producing them is limiting their use. That’s because a key component of the most common fuel cells is a catalyst made from the precious metal platinum. In a paper published today in Small,

Northwestern University researchers have developed a first-of-its-kind technique for creating entirely new classes of optical materials and devices that could lead to light bending and cloaking devices — news to make the ears of Star Trek’s Spock perk up. Using DNA as a key tool, the interdisciplinary team took gold nanoparticles of different sizes and

In an advance that could push cheap, ubiquitous solar power closer to reality, University of Michigan researchers have found a way to coax electrons to travel much further than was previously thought possible in the materials often used for organic solar cells and other organic semiconductors. “For years, people had treated the poor conductivity of
