Boeing unveils refreshed jet concept with ultra-thin wings
SAN DIEGO (Reuters) — Boeing Co unveiled a speedier and higher-flying version of a concept plane on Tuesday aimed at sharply reducing fuel use thanks to its elongated ultra-light wings.
The so-called Transonic Truss-Braced Wing aircraft boasts a 170-foot (52 meter) wingspan that sits atop the fuselage and is braced from underneath by a truss in a design reminiscent of biplanes from the early years of aviation.
The world’s largest planemaker and U.S. space agency NASA have been studying the concept plane for nearly a decade as part of the Subsonic Ultra Green Aircraft Research program. Boeing unveiled a reconfigured model or prototype and artist’s rendering at an aerospace conference in San Diego.

The 2018 Good Tech Awards
It’s true that this was a horrible year for many of the tech industry’s biggest companies. Amazon held a nationwide beauty pageant for its new headquarters, raising hopes that the company would help transform a struggling city, then picked the two places that needed it the least. Executives from Facebook, Google and Twitter got hauled before Congress to apologize for * gestures wildly in all directions*. One of Uber’s self-driving cars killed someone. And then there was Elon Musk.
But the tech sector is more than its giants.
Last year, I handed out “good tech” awards to a handful of companies, nonprofit organizations and people who used technology to help others in real, tangible ways. The goal was to shine a spotlight on a few less-heralded projects that may not get front-page headlines or billions of dollars in funding, but are actually trying to fulfill the tech industry’s stated goal of improving the world.

A self-driving car can choose who dies in a fatal crash. These are the ethical considerations
Can machines make moral choices?
A massive new survey developed by MIT researchers reveals some distinct global preferences concerning the ethics of autonomous vehicles, as well as some regional variations in those preferences.
The survey has global reach and a unique scale, with over 2 million online participants from over 200 countries weighing in on versions of a classic ethical conundrum, the “Trolley Problem.” The problem involves scenarios in which an accident involving a vehicle is imminent, and the vehicle must opt for one of two potentially fatal options. In the case of driverless cars, that might mean swerving toward a couple of people, rather than a large group of bystanders.
“The study is basically trying to understand the kinds of moral decisions that driverless cars might have to resort to,” says Edmond Awad, a postdoc at the MIT Media Lab and lead author of a new paper outlining the results of the project. “We don’t know yet how they should do that.”
