A brain-controlled exoskeleton has let a paralyzed man walk in the lab
The news: A paralyzed man has walked again thanks to a brain-controlled exoskeleton suit. Within the safety of a lab setting, he was also able to control the suit’s arms and hands, using two sensors implanted into his brain. The patient was a man from Lyon called Thibault, who fell 40 feet (12 meters) from a balcony four years ago, leaving him paralyzed from the shoulders down.
How it worked: Thibault had surgery to place two implants, each containing 64 electrodes, onto the parts of the brain that control movement. Software then translated the brainwaves read by these implants into instructions for movement. The development of the exoskeleton, by Clinatec and the University of Grenoble, is described in a paper in The Lancet this week.
Herculean effort: Thibault trained for months, using his brain signals to control a video game avatar in order to hone the skills required to operate exoskeleton, which was held up by a ceiling-mounted harness. He was able to walk slowly in the suit, and then stop, as he chose.
The future: The hope is that one day similar technology could eventually let people in wheelchairs move them using their minds. It’s an impressive breakthrough, but the device is many years away from being publicly available. For example, researchers need to find a way to get the suit to safely balance itself before it can be used outside the laboratory.

The Easiest Way to Access Emojis on MacOS
https://lifehacker.com/the-easiest-way-to-access-emojis-on-macos-1838778227
In a (failed) quest to remove a years-old custom keyboard shortcut from my MacBook Pro, I inadvertently found a handy option in the keyboard settings that makes accessing emojis on desktop much easier.
Open your system preferences, click “keyboard,” then check the box that says “show keyboard and emoji viewers in menu bar.” This will instantly create an icon in the toolbar at the top of your screen that will let you access emojis at any time. To insert them into a text field, double click the emoji you want.
Of course, you’ve always been able to access emojis on Mac by using the keyboard shortcut “control + command + space bar,” but having a separate window I can open up with a clickable shortcut is a nice option; I personally find the pop-up that appears when you use the keyboard shortcut to be a little janky. And remember, if you want to organize the way your toolbar shortcuts are laid out, hold down “command” while you click and drag to rearrange them however you like.

Kitty Hawk’s ‘Heaviside’ is an ultra-quiet electric flying machine
https://www.engadget.com/2019/10/04/project-heaviside-vtol/
As the field of players in "urban air mobility" (read: flying cars) get more crowded every day, the Larry Page-backed effort Kitty Hawk is trying a different approach with its latest vehicle: it’s very quiet. Dubbed Project Heaviside, it’s all-electric, flies like a plane but is capable of vertical take-off and landing (VTOL) like a helicopter, while being as much as 100 times quieter than a helicopter.
It’s also tiny, as you can make out in a picture with a person crouching next to the aircraft with seating for one. TechCrunch got up close and personal with Heaviside, noting that at the moment the cockpit seats its passenger on bare carbon fiber.
Kitty Hawk CEO Sebastian Thrun told TechCrunch "The calculus here is that this has to be socially acceptable for people," while demonstrating Heaviside’s capability to fly overhead without being any louder than an office air conditioner. It’s also intended to support both manual and autonomous flight, although regulatory approval could be quite a way off.

Already Working on 2nd Gen: AMD’s Ryzen Microsoft Surface Edition and what Semi-Custom Means
One of the key takeaways from Microsoft’s launch this week was that the company was spreading its wings with devices made by all three major SoC vendors: Intel, AMD, and Qualcomm. Both the AMD and Qualcomm design wins are especially important given that these companies did not traditionally have a foothold in this space. Both companies showcased unique silicon for Microsoft, with AMD’s Ryzen Microsoft Surface Edition going into the consumer-grade Surface Laptop 3, and Qualcomm’s Snapdragon SQ1 in the Surface Pro X. We sat down with AMD to get to grips with this partnership.

Schlieren System Captures Brilliant Shockwave Images
Supersonic flight over land is generally prohibited because sonic booms created by shockwaves disturb people on the ground and can damage property. Armstrong innovators are working to solve this problem with a novel system for capturing images of shockwaves created by supersonic aircraft. The Background Oriented Schlieren Using Celestial Objects (BOSCO) technology uses a celestial object, such as the Sun, as a background to secure unique, measurable shockwave images of full-scale aircraft. The patented image-processing technology captures hundreds of observations with each shockwave, benefitting NASA engineers in their efforts to develop a supersonic aircraft that will produce a soft “thump” in place of a disruptive sonic boom.
