Google simulates the human brain with 1000 machines, 16000 cores and a love of cats

Don’t tell Google, but its latest X lab project is something performed by the great internet public every day. For free. Mountain View’s secret lab stitched together 1,000 computers totaling 16,000 cores to form a neural network with over 1 billion connections, and sent it to YouTube looking for cats. Unlike the popular human time-sink, this was all in the name of science: specifically, simulating the human brain. The neural machine was presented with 10 million images taken from random videos, and went about teaching itself what our feline friends look like. Unlike similar experiments, where some manual guidance and supervision is involved, Google’s pseudo-brain was given no such assistance.

It wasn’t just about cats, of course — the broader aim was to see whether computers can learn face detection without labeled images. After studying the large set of image-data, the cluster revealed that indeed it could, in addition to being able to develop concepts for human body parts and — of course — cats. Overall, there was 15.8 percent accuracy in recognizing 20,000 object categories, which the researchers claim is a 70 percent jump over previous studies. Full details of the hows and whys will be presented at a forthcoming conference in Edinburgh.

This Is What Child Birth Looks Like, From the Inside [Science]

Back in 2010, a team of German doctors announced that they’d recorded the world’s first MRI of a woman giving birth. Back then, only still images were available—but now the researchers have released the video, and it’s spellbinding. More »

New wireless transmission tech hits 2.56Tbps, leaves WiFi feeling inadequate

New wireless transmission tech hits 256Tbps, leaves WiFi feeling inadequateStoked about the gigabit speeds your new 802.11ac WiFi router is pumping out? One group of scientists hailing from NASA’s Jet Propulsion Laboratory and universities in the US, Israel and China isn’t so impressed, having generated a wireless signal clocking in at 2.56Tbps. Proof of the feat was published in Nature Photonics, which details their use of orbital angular momentum (OAM) to make the magic happen. Current wireless protocols alter the spin angular momentum (SAM) of radio waves to hold info, and by combining both methods the team was able to pack eight data steams into a single signal, resulting in the mouth-watering number noted above. The best part is, applying different levels of OAM twist to SAM-based transmissions theoretically allows an infinite number of streams per signal, meaning seriously increased bandwidth without the need for additional frequency. So far the wireless tests have only been conducted over a measly 1m, but the scientists reckon it’ll work at distances up to 1km and that the concept could also be used to boost speeds in existing fiber-optic cables. As with many scientific advances, it’s unlikely hardware capable of such speeds will be available any time soon, so 802.11ac will have to suffice… for now.

Objet Ltd sets 100-material 3D printing record

A new, significant milestone has been reached in the world of 3D printing. You may know 3D printing as a neat, novelty kind of technological advancement that allows people to print their own mugs, earrings, etc. Or you may know it as a significant achievement in medical research. Or you may know it as something else. But there’s one thing that every application of 3D printing relies on – available printing material. That’s where Objet comes into place.

Objet, French for “Object,” of course, entered into a 3D printing merger with Stratasys earlier this year. That has boosted the company’s ability to rapidly expand its research and development to the point where, recently, it announced that it now has the technology to use 107 different materials in 3D printing applications. Most low-level commercial 3D printers only focus on one kind of plastic or similar substance.

But for industrial-grade purposes, there needs to be a lot more flexibility. Objet allows printing of flexible and rigid materials, opaque and transparent, and all manner of colors and shades. “Objet has become the first 3D printing company to break the 100 materials barrier. Considering that we had half this number just a few short years ago, this growth in material choice confirms our commitment to consistently deliver new and enhanced material properties to our customer,” the company said in a statement.

SlashGear Evening Wrap-Up: June 25, 2012

Happy Monday, everyone. As we roll into the final week of June, there’s one major thing to watch – Google’s I/O conference, the annual event where we get all the major Google/Android announcements. Until those fully trickle in, though, here’s what made news today – Xbox Kinect $99 deal starts today, T-Mobile customers consider Galaxy S III vs Galaxy Note, and Apple releases iOS 6 beta 2 to developers. That’s just the beginning. Read on for more stories…

Featured: So our featured articles usually either take a look at a specific product or at a major event or announcement that is just hitting the airwaves. Today’s features fall into the latter category. Up first we have a column from our Chris Burns – Facebook Find Friends Nearby is a symptom of a larger social disease. And also, another column from SlashGear’s Chris Davies – Apple, Microsoft, now Google: I/O 2012 closes the mobility triptych.

Dollar General, Mars, & Helicopters: Have you ever seen a stranger mash-up of headlines before? It’s not often Dollar General comes into our scope. In fact, I’d venture to guess that it has been never. Until now. T-Mobile teams with Dollar General stores for monthly 4G and prepaid services. And moving right along into exciting space news – Mars curiosity landing sequence demonstrated by NASA. And if that wasn’t cool enough for you – Human-powered helicopter breaks world record.

Human-powered helicopter breaks world record

This week we’ve got a human-powered helicopter out there in the world that’s flown a larger amount of time than any human-powered helicopter in the history of the world. This device is called the Gamera II, and is essentially a mass of metal, cables, and one human being. There are four rotor blades, the vehicle is 105 feet across, and the whole thing weighs in at just 71 pounds.

What you’ve got here is a system of cables that allows the pilot to fly the system, and with this much more difficult than it looks amalgamation, a team of University of Maryland Students have broken the flight duration record by a whole heck of a lot. With the last record for such a system being 11.4 seconds (and incidentally set by the first version of this same vehicle), a massive 50 second flight this time around has solidly set this group of engineers in the history books.

The university’s school of engineering’s Alfred Gessow Rotocraft Center has been credited with the creation of the device, and the team is moving ever closer to the coveted Sikorsky Prize for just such a craft. The Sikorsky Prize is given by the American Helicopter Society and requires that a winning entry hover 10 feet off the ground for 60 seconds. The team responsible for the Gamera II will continue their quest for hitting those requirements throughout the summer (and possibly beyond). Have a peek at the 50-second test here:

Creating a craft such as this has its risks, one of which is drifting into a wall since the craft doesn’t have much in the way of directional control. We expect this team to break the record again very soon.

Scientists create wireless connection capable of 2.5 terabits per second

American and Israeli scientists have developed a new system of wirelessly transmitting data using twisted beams of light that could produce a theoretical throughput of 2.5 terabits of data per second. For perspective, that’s more than 8,000 times faster than Verizon’s fastest home Internet connection known as FiOS, which boasts 300Mbps. At this speed you can transfer seven full Blu-ray movies per second.

The new method of twisted signals uses orbital angular momentum (OAM) to put more data into a single stream. ExtremeTech explained it well:

In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM.

The researchers twisted together eight 300Gbps visible light data streams using OAM over a space of one meter to achieve speeds of 2.5 terabits per second. The development comes just one month after it was finally proved that OAM is actually possible. With OAM, an infinite number of conventional transmission protocols, such as WIFi and LTE, can be twisted together for faster speeds without the need for more spectrum.

The team will be working increasing the transmission distance next, which currently at only 1 meter is not so useful. The limit in distance for this new method is likely to be under 1km.

Students Set Record for Human-Powered Helicopter

A team of students at the University of Maryland A. James Clark School of Engineering have been hard at work trying to perfect one of the ideas that many inventors and pioneers of aviation have tried to achieve for many, many decades. That goal is human-powered helicopter flight. The students have set an unofficial flight duration benchmark with their pedal-powered helicopter dubbed the Gamera II.

human copter

The team set the unofficial flight duration record on June 20, with a time of 35 seconds. The 30-second flight has to be verified by the National Aeronautic Association and if verified will become the new record superseding the teams previous record of 11.4 seconds set last summer. The team of students is only the third team to achieve human-powered helicopter flight.

The team is vying for $250,000 prize if they can become first team to build a helicopter powered only by person to liftoff and hover for 60 seconds. The helicopter has to attain a height of at least 3 meters at some point during the 60-second flight and stay within a ten square meter area for the duration of the flight. You can check out the video of the June 20 flight above.
