Some materials, like wood, are insulators that block the flow of electricity. Conductors, such as copper, allow for electricity to flow through them. Other materials—semiconductors—can be either/or depending on conditions such as applied electric field or temperature. Unlike wood or copper or silicon, though, topological insulators (TIs) are an exotic... Read more

As Wi-Fi is deployed more widely in cities, and perhaps at higher frequencies, it may depend on an abundant urban asset: streetlight poles.... Read more

One of many special human qualities is the ability to handle objects with skill and precision. This is all down to our sense of touch, which is particularly acute in the tips of our fingers. Using our hands, we are able to explore the shape and composition of objects and... Read more

A team of international scientists have performed difficult machine learning computations using a nano-scale device, named an "optomemristor."... Read more

In April 2022, the project "Smart Electronic Olfaction for Body Odor Diagnostics"—SMELLODI for short—started with the kick-off meeting. The objective of the seven partners from Germany, Israel and Finland is to develop intelligent electronic sensor systems that can distinguish between healthy body odors and those altered by disease and transmit...

A pop-up urban port for delivery drones—and one day, potentially flying taxis—launched Monday in Britain, lifting a box of prosecco for a brief celebratory test flight hailed as groundbreaking.... Read more

The National Aeronautics and Space Administration (NASA) announced April 15 it has awarded Lawrence Livermore National Laboratory (LLNL) and a private company with funding to develop LLNL's revolutionary volumetric additive manufacturing (VAM) 3D printing technology to produce artificial cartilage tissue in space....

Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their... Read more

Standard image sensors, like the billion or so already installed in practically every smartphone in use today, capture light intensity and color. Relying on common, off-the-shelf sensor technology—known as CMOS—these cameras have grown smaller and more powerful by the year and now offer tens-of-megapixels resolution. But they've still seen in... Read more

You are standing in an apartment when you hear on the news that an earthquake has struck. Soon you feel your body sway and the ground starts to shake, the intensity increasing until the shelves on the walls and items on the table fall off.... Read more

One way farmers learn best practices is through their peers, but the pandemic has limited in-person meetings.... Read more

Speech recognition technology allows us to ask Siri to check the weather for tomorrow, or to ask Alexa to play our favorite song.... Read more

When Tony Stark needs to travel to space in the original Iron Man movie, he asks his artificial intelligent (AI) assistant J.A.R.V.I.S. to make a suit that can survive harsh conditions.... Read more

Picture a birthday card that flickers between images of a birthday cake and flowers as you turn the card and view it from different angles. No doubt you can think of other examples of such morphing images in, say, advertisements. Until now, however, the effect has been limited to flat... Read more

Riddell has developed a football helmet that might not be just the next big step in design and player safety, but a major leap.... Read more
