Electronic skin can display a heartbeat on your hand
Electronic skins might not only detect health troubles in the near future, but display them for the world to see. University of Tokyo researchers have developed an e-skin that can measure vital signs like your heartbeat and display them in real time on a skin display. The design blends a breathable nanomesh electrode and stretchable wiring with an array of micro LEDs that can output basic images bending with your body. Others know right away if you need help -- they'd just have to look at your hand (or anywhere else the sensor works) to get an idea of what's wrong. The sensor can pair with a smartphone and transmit its info to the cloud, too.
Adding a second pair of arms is as easy as putting on a backpack
There's only so much you can do with two arms and hands. That's basic science. But what if you could add extras without the need for ethically shady surgery or trading your apartment for a hovel in the shadow of a nuclear power plant? That's what researchers from Keio University and the University of Tokyo hope to achieve with their "Metalimbs" project. As the name suggests, Metalimbs are a pair of metal, robotic arms that doubles the amount of torso-extremities and worn with a backpack of sorts. And unlike thought-powered prosthetics we've seen recently, these are controlled not with your brain, but your existing limbs. Specifically, your legs and feet.
How artificial intelligence can be corrupted to repress free speech
The internet was supposed to become an overwhelming democratizing force against illiberal administrations. It didn't. It was supposed to open repressed citizens' eyes, expose them to new democratic ideals and help them rise up against their authoritarian governments in declaring their basic human rights. It hasn't. It was supposed to be inherently resistant to centralized control. It isn't.
ICYMI: Birds the magical flying machines

Japanese AI abandons its Tokyo University dreams
A team of scientists from the National Institute of Informatics in Japan have given up on making their AI smart enough to get into the University of Tokyo. The Todai Project -- Tokyo University's local nickname is "Todai" -- began in 2011, so we're sure at least some of them were disappointed by the decision. But, hey, this means robots aren't as smart as humans yet, and we don't have to fear an uprising in the near future. The researchers were hoping that the AI would score much higher than the 511 out of 950 it got last year when it took a standardized entrance exam in the country. Unfortunately, its overall results were pretty much the same for 2016.
ICYMI: Robots so advanced, they cool themselves with sweat
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: Researchers from the University of Tokyo devised a better air cooling system for robots that is modeled on their as-yet-overlords, sweaty humans. The 3D-printed bones have spaces for tiny pores, allowing Kengoro to do pushups for 11 minutes without overheating. Next up, world domination.
IBM's Watson AI saved a woman from leukemia
IBM's Watson has done everything from winning at Jeopardy to cooking exotic meals, but it appears to have accomplished its greatest feat yet: saving a life. University of Tokyo doctors report that the artificial intelligence diagnosed a 60-year-old woman's rare form of leukemia that had been incorrectly identified months earlier. The analytical machine took just 10 minutes to compare the patient's genetic changes with a database of 20 million cancer research papers, delivering an accurate diagnosis and leading to proper treatment that had proven elusive. Watson has also identified another rare form of leukemia in another patient, the university says.
Extra-thin LEDs put a screen on your skin
Eventually, wearable displays might be so thin that they effectively blend into your skin. University of Tokyo researchers have developed an optoelectronic skin whose polymer LEDs and organic photodetectors are so thin (3 micrometers) that they practically blend in with your body. If it weren't for the thin film needed to attach the display in the first place, it'd look like a tattoo. The technology more efficient than previous attempts at these skins, running several days at a time, and it's durable enough that it won't break as you flex your limbs.
AI has a better shot at Tokyo University than your kid
Students in Japan could soon compete with AI to get into colleges. The National Institute of Informatics in Tokyo has developed a program that scored above average on a standardized entrance exam that covered math, physics, English and history. The AI scored 511 out of 950, beating the national average of 416. While it was expected to do well on the math test, it did exceedingly well on the history questions that required natural learning processing skills to make inferences.
Super-fast projector may be key to holodeck-like rooms
Projection mapping theoretically adds a Holodeck-like level of immersion to simulations, but current projectors are simply too slow to keep up with fast-moving people. That won't be an issue if University of Tokyo researchers have their way. They've developed DynaFlash, a 1,000 frames per second projector that can keep up with just about any moving object. It can't beam images into thin air, like you see above (that's just for show), but it can seemingly do everything else -- even if you shake or spin an object very quickly, you'll still get the image where you wanted it to be. The trick involves adding a special controller to a DLP (digital light processing) projector that, combined with fast image output, delivers both high frame rates and low latency.
Stretchy conductive ink puts computing power on your clothes
Those dreams of having computers in your clothing might be more realistic than you think. Japanese researchers have developed a printable conductive ink that maintains a circuit even when you stretch fabric to three times its usual length -- you could have athletic gear with hidden activity trackers, sensors and other computing devices. The key is a careful mix of fluorine, an organic solvent and silver flakes which, when combined, keeps transmitting electricity even under heavy abuse.
Japanese robot moves heavy objects by putting its back into it
When you need to move something but it's too heavy to lift off the ground, most of us default to one of two strategies: find someone stronger, or shove it along the floor instead. Researchers from the University of Tokyo's JSK Laboratory are now teaching robots to do the latter. The latest version of its HRP-2 is able to analyse an object, say a heavy crate on tiny rollers, and try different methods of exerting force. Much like a human, lower force strategies mean pushing or pulling with its hands, while higher strength methods include leaning in with a single shoulder or its back. The robot will monitor each attempt and automatically switch to increasingly higher force strategies if it finds the object still isn't moving. Depending on its progress, the HRP-2 will also alter its footwork to ensure it doesn't fall over; a slow-moving object might require shorter steps, for instance, to make sure it's not caught off guard by a sudden change in resistance. It can't replace your local moving company (yet), but it's nice to see a robot finally putting its back into something.
Basics of quantum teleportation now fit on a single chip
Until now, quantum teleportation (that is, sending quantum data from one place to another) has required a room-filling machine. That's not going to usher in a brave new era of quantum computing, is it? However, a team of British and Japanese researchers has shrunk things down to a much more reasonable size. They've stuffed the core optical circuits for quantum teleportation into a single silicon chip that's just slightly longer than a penny -- in contrast, an experimental device from 2013 was nearly 14 feet long. While scientists built the chip using "state-of-the-art nano-fabrication," it should be more practical to make than its ancestors, which took months.
'Spooky' experiment proves quantum entanglement is real
Einstein was wrong -- about the quantum mechanical phenomena known as superpositioning and wave form collapse, at least. A team from Australia's Griffith University and Japan's University of Tokyo, have proven that both are tangible phenomena, not simply mathematical paradoxes. See, back when he was still reigning "smartest guy on the planet," Einstein just couldn't wrap his massive intellect around the theory of superpositioning (or as he called it, "spooky action across distance"). That is, a particle in superposition effectively exists in both places at once (not unlike Schroedinger's Cat) until you observe it at either location. At which time the particle you aren't looking at ceases to exist (a process known as wave function collapse). What's more, the disappearing particle seems to know that its twin has been discovered through some mechanism that happens instantly, literally traveling faster than the speed of light -- a clear violation of Einstein's theory of relativity.
This camera can snap chemical reactions at a trillionth of a second
You know those high-speed cameras used to film mesmerizing ultra slo-mo videos? They're downright slow compared to this one developed by researchers from The University of Tokyo and Keio University in Japan. The 12-man science team has just revealed an extremely speedy camera that can take pictures of chemical reactions (in burst mode, as those are impossible to capture in a single shot) at 450 x 450 pixels. It's called the Sequentially Timed All-optical Mapping Photography or STAMP cam, and it can capture consecutive images at a rate of one per every one-trillionth of a second. To note, other high-speed cameras capture one image per every one-billionth of a second. The device is supposed to be 1,000 times faster than comparable models and has even managed to snap a picture of heat conduction (a process that takes, oh, 1/6th the speed of light) during a test.
Scientists get a shark's eye view using wearable computers
Sure, Sharknado and Sharktopus are fun to watch with friends on a weekend, but they also prove that sharks still get a bad rap. Clearly, what we've learned about the animal's behavior since Jaws came out isn't nearly enough, so a group of researchers are attempting to find out more... by strapping a bunch of gadgets to a bunch of sharks. Think of these things as a combination of a GoPro and a sportsband -- they're equipped with sensors and cameras that monitor and video a shark's adventures.
Watch an ultrasonic array move objects in 3D space (video)
Ultrasonic levitation has been possible for awhile, but it's not very practical when objects must typically hover along a single axis. University of Tokyo researchers Yoichi Ochiai, Takayuki Hoshi and Jun Rekimoto have cleared this hurdle with an ultrasonic array that can push items around in 3D space. The machine creates a focal point from a three-dimensional standing wave; users just have to alter the wave's properties to move whatever is caught inside that point. The technique can manipulate a wide range of materials, and it's safe to disrupt with your hands. While the array will need to scale up before it lifts objects much larger than matchsticks or screws, it already shows that we don't need exotic technologies like tractor beams to float things through the air.
Ultra-thin e-skin could lead to advances in medicine, cool wearable computing (video)
Remember the names Martin Kaltenbrunner and Takao Someya -- that way, you'll have someone to blame when kids start pointing and laughing at gadgets we consider high-tech today. Leading a team of University of Tokyo researchers, they have recently developed a flexible, skin-like material that can detect pressure while also being virtually indestructible. Think of the possibilities: with a thickness of one nanometer, this could be used to create a second skin that can monitor your vital signs or medical implants that you can barely feel, if at all. Also, temperature sensors could be added to make life-like skin for prosthetics... or even robots! Like other similar studies, however, the researchers have a long journey ahead before we see this super-thin material in medicine. Since it could lead to bendy gadgets and wearable electronics first, don't be surprised if your children call iPhones "so 2013" in the not-too-distant future.
Japanese robots Kirobo and Mirata set for launch, literally
Don't get excited about buying the new robots created by Japanese company Dentsu in conjunction with Toyota and the University of Tokyo -- they won't be hitting stores anytime soon. However, do get excited that one of them, namely the white-helmeted droid Kirobo (shown above, left), will actually be launched into orbit as part of a Japan Space Agency mission to the ISS on August 4th. In fact, he and his backup Mirata were endowed with voice recognition, natural language processing, speech synthesis, realistic body language and facial recognition for that very reason. They'll be participating in the "world's first conversational experiment" between people and robots in space, while also mixing it up with kids on earth with educational activities. Hopefully, the astronauts won't give Kirobo any HAL 9000-like control of the station, though the cute 'bots seem malice-free, saying they "wanted to create a future where humans and robots live together and get along." Check it out for yourself in the video after the break.
University of Tokyo's fast-tracking camera system could revolutionize sports coverage (video)
Researchers at the University of Tokyo's Ishikawa Oku Lab have been hard at work on a camera system that can track fast moving objects incredibly well, and the technology may change the way sports like baseball and soccer are televised. Recently, the team building the system has entered the next phase of testing: taking it outside, to see if will perform as well as it has in a lab setting. If all goes according to plan, they expect it'll be ready for broadcast use in roughly two years. Demos of the tech are pretty impressive, as you can see in the video below showing the (warning: not recommended watching for those easily prone to motion sickness). To get the ping-pong ball-centric shots, the system uses a group of lenses and two small mirrors that pan, tilt and move so the camera itself doesn't have to. The mirrors rely on a speedy image tracking system that follows movement, rather than predicting it. Swapping the camera out for a projector also has some interesting applications -- it can paint digital pictures on whatever its tracking. Sounds like the perfect gadget for folks who wish their table tennis balls looked like emoji.
