A male fruit fly in a laboratory chamber extends his wings and vibrates them to produce his species’ version of a love song. A female fly stays nearby listening. Suddenly, a green light flashes across […]
3D bioprinting, in which living tissues are printed with cells mixed into soft hydrogels, or “bio-inks,” is widely used in the field of bioengineering for modeling or replacing the tissues in our bodies. The print […]
A little-known fact: In the year 1900, electric cars outnumbered gas-powered ones on the American road. The lead-acid auto battery of the time, courtesy of Thomas Edison, was expensive and had a range of only […]
It’s a typical workday and you sign onto your computer. Unbeknownst to you, a high-frequency sensing system embedded in your work device is now tracking your heart rate, allowing your employer to monitor your breaks, […]
Soft robots made out of flexible, biocompatible materials are in high demand in industries from health care to manufacturing, but precisely designing and controlling such robots for specific purposes is a perennial challenge. What if […]
Researchers have fabricated a hair-thin microphone made entirely of silica fiber that can detect a large range of ultrasound frequencies beyond the reach of the human ear. Able to withstand temperatures up to 1,000°C, the […]
A team of EPFL researchers has taken a major step towards resolving the problem of drift in generative video, which is what causes sequences to become incoherent after a handful of seconds. Their breakthrough paves […]
Tungsten carbide–cobalt (WC–Co) is prized for its hardness, but that same property makes it unusually difficult to shape. The current process is wasteful and expensive for the yield produced, and an economically sensible method for […]
In a typical online meeting, humans don’t always wait politely for their turn to speak. They interrupt to express strong agreement, stay silent when they are unsure, and let their personalities shape the flow of […]
Metamaterials—materials whose properties are primarily dictated by their internal microstructure, and not their chemical makeup—have been redefining the engineering materials space for the last decade. To date, however, most metamaterials have been lightweight options designed […]
