MetaLimbs is a robotic system that provides the wearer with an extra pair of arms. The mechanical arms are controlled by the user's legs, feet, and toes. The researchers from Keio University and the University of Tokyo will present their work at next month's SIGGRAPH 2017 conference in Los Angeles.
Researchers from the Technical University of Denmark demonstrated a new nanotechnology-based printing technique that produces long-lasting color images on plastic at resolutions up to 127,000 dots per inch, many times more detailed than traditional laser printers. The system uses a laser to alter the structure of nanoscale structures on the plastic material. (A nanometer is one-billionth of a meter; a human hair is around 60,000 nanometers in diameter.) The nanoprinting technique could also lead to new kinds of 3D displays or invisible watermarks. From New Scientist:
The surface of the plastic is shaped so that it has lots of tiny pillars, one roughly every 200 nanometers. A thin film of the element germanium is then spread over the plastic. Heat from a laser melts the germanium on each pillar, morphing its shape and thickness. As a result, it reflects a specific color. The coating protects the shapes of the newly carved nanostructures.
This is NASA's new "space fabric" in development at the Jet Propulsion Laboratory.

1. Visions not goals
2. Fund people not projects — the scientists find the problems not the funders. So, for many reasons, you have to have the best researchers.
3. Problem Finding — not just Problem Solving
4. Milestones not deadlines
5. It’s “baseball” not “golf” — batting .350 is very good in a high aspiration high risk area. Not getting a hit is not failure but the overhead for getting hits. (As in baseball, an “error” is failing to pull off something that is technically feasible.)
6. It’s about shaping “computer stuff” to human ends per the vision. Much of the time this required the researchers to design and build pretty much everything, including much of the hardware — including a variety of mainframes — and virtually all of the software needed (including OSs and programming languages, etc.). Many of the ARPA researchers were quite fluent in both HW and SW (though usually better at one than the other). This made for a pretty homogeneous computing culture and great synergy in most projects.
7. The above goes against the commonsense idea that “computer people should not try to make their own tools (because of the infinite Turing Tarpit that results)”.

Drone manufacturer DJI published a white paper proposing a kind of license plate for drones in the form of a wireless identifier that the buzzing UAVs would be required to broadcast. The paper describes a possible way to balance the privacy of drone operators with perceived public concern about whose controlling the bots buzzing overhead. You can read the full paper as a PDF here. From David Schneider's column in IEEE Spectrum:

As the company points out in its whitepaper, drone operators might want to maintain anonymity even if there were people around to witness their flights. Suppose, for example, that a company were surveying land in anticipation of purchasing and developing it. That company might not want to clue in competitors. Or perhaps the drone is being flown for the purposes of investigative journalism, in which case the journalists involved might not want others to know about their investigations.
DJI proposes that drones be required to broadcast an identifying code by radio . . . That code would not include the name and address of the owner, but authorities would be able to use it to look that information up in a non-public database—a kind of electronic license plates for drones.
At the same time, it’s easy to understand why law-enforcement or regulatory authorities would sometimes want to identify the owner or operator of a drone, say, if somebody felt the drone were invading their privacy or if a drone were being flown close to a nuclear power plant.
The public bathroom at Beijing's Temple of Heaven Park now has a toilet paper dispenser outfitted with a camera and facial recognition technology to prevent toilet paper theft. From the New York Times:
Before entering restrooms in the park, visitors must now stare into a computer mounted on the wall for three seconds before a machine dispenses a sheet of toilet paper, precisely two feet in length. If visitors require more, they are out of luck. The machine will not dispense a second roll to the same person for nine minutes.
At the Temple of Heaven Park, one of Beijing’s busiest tourist sites, many people said on Monday they were pleased by the new machines.
“The people who steal toilet paper are greedy,” said He Zhiqiang, 19, a customer service worker from the northwestern region of Ningxia. “Toilet paper is a public resource. We need to prevent waste...”
I agree with park visitor Wang Jianquan, 63: “The sheets are too short."
Poking a golden tortoise beetle ("goldbug") triggers the insect's color to change from gold to a red-orange. Inspired by the natural system underlying that insectoid superpower, MIT researchers have developed flexible sensors circuits that can be 3-D printed. Eventually, the technology could lead to sensor-laden skin for robots. From MIT News:

“In nature, networks of sensors and interconnects are called sensorimotor pathways,” says Subramanian Sundaram, an MIT graduate student in electrical engineering and computer science (EECS), who led the project. “We were trying to see whether we could replicate sensorimotor pathways inside a 3-D-printed object. So we considered the simplest organism we could find...."
The MIT researchers’ new device is approximately T-shaped, but with a wide, squat base and an elongated crossbar. The crossbar is made from an elastic plastic, with a strip of silver running its length; in the researchers’ experiments, electrodes were connected to the crossbar’s ends. The base of the T is made from a more rigid plastic. It includes two printed transistors and what the researchers call a “pixel,” a circle of semiconducting polymer whose color changes when the crossbars stretch, modifying the electrical resistance of the silver strip.
In fact, the transistors and the pixel are made from the same material; the transistors also change color slightly when the crossbars stretch. The effect is more dramatic in the pixel, however, because the transistors amplify the electrical signal from the crossbar. Demonstrating working transistors was essential, Sundaram says, because large, dense sensor arrays require some capacity for onboard signal processing.
MNTNT's Albert Clock is a clock that presents the hours and minutes as simple math problems. Is it annoying or engaging? Or.... both!
In standard mode, the queries change every minute. They are completely random, so even the query for the hours change, even if the result stays the same.
You can speed up this challenge so the queries change in the fastest mode every 10 seconds.
You can also download the Albert Clock as a free mobile app.
