MIT researchers have designed a completely flat wide-angle lens that can produce clear, 180-degree images, reports Darrell Etherington for TechCrunch. “The engineers were able to make it work by patterning a thin wafer of glass on one side with microscopic, three-dimensional structures that are positioned very precisely in order to scatter any inbound light in precisely the same way that a curved piece of glass would,” writes Etherington.

The Takeaway

Tanzina Vega of The Takeaway speaks with WGBH reporter Kirk Carapezza about how MIT is training workers in the field of integrated photonics to help fill a labor gap. “MIT has been working with community college students, helping them get internships,” explains Carapezza, “and trying to simultaneously develop the technology and train people how to use it.”

Scientific American

Scientific American reporter Prachi Patel writes that a new study by Prof. Elsa Olivetti found that demand for cobalt, which is critical to electric vehicle batteries, could soon outstrip supply. “The best lithium battery cathodes [negative electrodes] all contain cobalt, and its production is limited,” Olivetti explains.
