The Brilliant Vigilance of Seattle’s Gargantuan New Tunnel

Say there’s a fire. A fire caused by a car crash, inside a 2.5-mile tunnel under a major American city. It’s a terrifying idea, but if you want that kind of problem to ignite anywhere, it’s in the stretch of State Route 99 that, later this year, will start whisking traffic underneath downtown Seattle. That’s because this bit of SR 99 is more than the hemisphere’s largest-diameter bored tunnel and the country’s longest roadway tunnel outside of Alaska, much of it dug by Bertha, formerly the planet’s largest boring machine.…

This Gadget Communicates Human Emotions Through Touch

Ask engineers what the future of communication looks like and they’ll show you a fiber-optic cable. Ask artists and they’ll conjure something like the Sleeve. For the past year, engineers at Nokia Bell Labs, the famed New Jersey research facility that birthed the transistor, have been developing this wearable armband with input from artistic collaborators. “We’re reductionist in our thinking; artists are divergent,” research lead Domhnaill Hernon says. The labmates are part of a ­program called Experiments in Art and Technology, founded in the ’60s and newly resurrected in partnership…

So far, the theme seems to be retro-chic. McLaren has gone for an “papaya” orange and blue livery for its MCL33 car, inspired by its early 1970s racing machines. Ferrari’s SF-71H has returned to a classic red, dropping last year’s splashes of white. Red Bull is being cagey about its competition colors, revealing its new RB14 in…
