Broadband A Go-Go

In city after city, high-speed wireless access may be the next Internet revolution

11 min read

I've got a Dell laptop on my knees and the wind is in my (very short) hair. I've got as many windows open as a beach house in summer—Google searches and instant messages to my wife; in the background, a new batch of e-mails downloads and my hometown public radio station streams on. It's the usual cruise down the information superhighway at 2 Mb/s.

But I'm also hurtling down an actual superhighway—U.S. Interstate 4, at a very real 115 km/h. I'm in a Ford Mustang convertible, under cotton-ball clouds and a postcard-blue Florida sky. The Dell is outfitted with a prototype card that communicates with a test network set up by broadband wireless start-up MeshNetworks Inc.

Engineers Are Working on a Solar Microgrid to Outlast Lunar Nights

Future lunar bases will need power for mining and astronaut survival

The next time humans land on the moon, they intend to stay awhile. For the Artemis program, NASA and its collaborators want to build a sustained presence on the moon, which includes setting up a base where astronauts can live and work.

One of the crucial elements for a functioning lunar base is a power supply. Sandia National Laboratories, a research and development lab that specializes in building microgrids for military bases, is teaming up with NASA to design one that will work on the moon.

Trilobite-Inspired Camera Boasts Huge Depth of Field

New camera relies on “metalenses” that could be fabricated using a standard CMOS foundry

Inspired by the eyes of extinct trilobites, researchers have created a miniature camera with a record-setting depth of field—the distance over which a camera can produce sharp images in a single photo. Their new study reveals that with the aid of artificial intelligence, their device can simultaneously image objects as near as 3 centimeters and as far away as 1.7 kilometers.

Five hundred million years ago, the oceans teemed with horseshoe-crab-like trilobites. Among the most successful of all early animals, these armored invertebrates lived on Earth for roughly 270 million years before going extinct.
