At the pace of 30 videos a day, Next Media Animation is churning out “All the news that’s fit to animate.” The Taiwanese media company is (in)famous for hilarious and hilariously inappropriate news videos reenacting Tiger Woods’ car crash and TSA’s new full body scanners. It’s the day after the Super Bowl and their video featuring Eli Manning, God, and a “geriatric Lady Gaga Impersonator” (aka Madonna) has already been up for hours. How does it happen so fast? The answer is a huge team of animators but also one particular programming whiz. Eliza Strickland at IEEE Spectrum has a profile of Kevin Wang, the guy who makes it all possible:

Computer Learns to Take Over Virtual Worlds by Doing What Most of Us Don’t: Reading the Manual
Screenshot of Civilization IV, a later version
of the game that MIT’s computer played.
What’s the News: Many video gamers scoff at the idea of actually reading the instruction manual for a game. But a manual can not only teach you how to play a game, it can also give you the basics of language—that is, if you’re a machine-learning computer. Researchers at MIT’s Computer Science and Artificial Intelligence Lab have now designed a computer system that can learn the meaning of certain words by playing complex games like Civilization II and comparing on-screen information to the game’s instruction manual.
Google’s Facebook-Like Anti-Facebook Aims for Privacy & Freedom
What’s the News: To much fanfare, Google has released a preview version of Google+, their long-anticipated move into the social-networking space dominated in the U.S. by Facebook, whose meteoric growth challenges Google’s dominance over the Web itself. The new service lets users send messages and pictures to each other, like Facebook, but puts more emphasis on grouping and communicating with varying-sized audiences, as with email or in the real world of meatspace.
The two consensus early reactions (from the small group of people who have access) are that the service is mostly smooth and functional, a welcome change after Google’s social flops Buzz and Wave; and that it sure looks a heck of a lot like Facebook. Will that be enough to challenge Facebook, whose enormous base of users have uploaded much of their lives to one social network and may not want to invest time in another?
DNA Computer Does Math, Plus Lays Out Building Blocks For Bigger Circuits

Diagram of the new DNA circuit
What’s the News: Researchers have built the most complex DNA-based computer yet, a circuit of 130 strands of DNA that can compute the square root of numbers up to 15. The system, reported today in Science, is made of biological logic gates, which do computations using DNA strands’ natural propensity to zip and unzip. This new method is easily adapted for different calculations and can be automated, meaning it could be used to build much larger circuits.
Intel Says “Fins” on Its New Transistors Are an Electronics Revolution

What’s the News: The foundation of modern electronics, silicon transistors are miniature on/off switches that regulate electric current. This week, Intel demonstrated a new transistor design that’s being hailed by Intel as one of the most radical developments in transistors since the advent of integrated circuits of the 1950s. By adding tiny, vertical fins to normally flat transistors, Intel’s new Tri-Gate transistor allows for faster, smaller, and lower-voltage computer chips. “We’ve been talking about these 3-D circuits for more than 10 years, but no one has had the confidence to move them into manufacturing,” chip-manufacturing specialist Dan Hutcheson told The Wall Street Journal.

Crowdsourcing: Using Language Students to Translate the Internet

With Luis von Ahn’s reCAPTCHA, users help
correct distorted words in digitized books.
What’s the News: Nothing…yet! But word is that Luis von Ahn–the Carnegie Mellon professor behind the clever projects reCAPTCHA and ESP Game–is bringing his crowdsourcing know-how to bear on the problem of web translation. With Duolingo, a project his lab has been working on for the last year and a half, people learning new languages will serve as translators. How well will that work? It remains to be seen, but according to von Ahn, a private beta version should be launching in several weeks.
Economist: Online Games’ Virtual Economies Provide Big Money to the Developing World

What’s the News: Just as the real-world economy is crawling out of a recession, the virtual economy based around online games like World of Warcraft is booming to the tune of $3 billion per year. This money is actually making a measurable economic impact in developing countries, providing up to 100,000 jobs in China and Vietnam. According to Tim Kelly, the Lead ICT Policy Specialist of infoDev, a technology development finance program of the World Bank and IFC, “This could significantly boost local economies and support further development of digital infrastructure in regions such as Africa and southeast Asia.”
“Sexy Math” Helps App Amp Up Car Services
What’s the News: Cool new apps come out every day, but not every app comes with its own car service. Starting in San Francisco, one company lets pedestrians hail a car using their iPhone or Android phone (or any old text-messaging clunker), providing a more expensive, yet faster alternative to cabs. To make this possible, computer scientists had to find a way to make driving routes as efficient as possible, which is actually quite complicated when you’re dealing with a city-ful of car-hailing people. As Uber CEO Travis Kalanick told Wired, “It’s really fun, sexy math.”
Physicists Find New Way to Store Quantum Information in Impure Diamonds
What’s the News: Physicists have worked out a new method of storing information in the quantum states of atoms in diamond crystals. The scientists linked the spin of individual nitrogen atoms in the diamond—impurities at the jewelry counter, but boons in the physics lab—to the spin of nearby electrons. They could form a quantum link between the spin of the nitrogen atom and the spin of a nearby electron, letting the electron store information more stably than if it were spinning on its own.
How the Heck:
- When a nitrogen is next to an empty spot in a diamond’s carbon framework, it lets off an extra electron, leaving that electron free to have its quantum played around with.
- Using what they call “intense microwave fields” [PDF], the physicists were able to link the spin of a nitrogen atom to a neighboring electron, a pairing sparked by magnetic fields.
What’s the Context:
- Scientists have been looking at diamonds—with and without nitrogen impurities—as a quantum computing material for several years, in part because it can store quantum memory at room temperature, not the far-below-freezing temps required by some other materials.
- Some have even proposed the idea of diamond supercomputers, which would store millions of times as much data as today’s machines.
- One hurdle in quantum computing is getting the information to last long enough to use it. In the recent study, the nuclear spin stayed coherent for more than a millisecond—enough time for a ten petaflop supercomputer to do ten trillion operations.
Not so Fast:
- Don’t start rooting around in your hard drive for a rock just yet; diamond-based quantum computing is still a long way off.

Nerve Cells Reach Out and Touch Someone: Electronic Components
What’s the News: Scientists have discovered a new technique for linking semiconducting tubes with mouse nerve cell tendrils: They let the cells do the work for them. After creating biologically friendly semiconductor tubes, they found that nerve cells’ tendril-like axons didn’t shy away. “They seem to like the tubes,” University of Wisconsin-Madison biomedical engineer Justin Williams told Science News. This represents a step toward new technology involving computer-brain networks.
How the Heck: The trick was to create tubes of layered germanium and silicone (which insulate the nerve’s electrical signals) that were big enough for the nerve cell’s threadlike projections to enter but too small for the cell body: When seeded with live mouse nerve cells, the only way the cells could interact with the tubes was be sending tendrils into it—which is just what they did.
What’s the Context:
- This research builds upon some work done in previous studies, where researchers actively connected nerves to semiconductors.
- Science Not Fiction and 80beats have covered other methods of connecting neurons and electronics.
- Which shouldn’t be confused with the development of a brain-like chip. Or the debate over whether random data can become conscious.
Not So Fast: The researchers don’t yet know whether the connected nerves are actually talking with each other.
Next Up: Now they want to hook the tubes to voltage sensors that can “listen” to the cells communicating with each other. If successful, this could lead to new drug tests where doctors can actually measure how nerve cells respond to certain types of drugs, leading to further innovations in the battle against neurological diseases like Parkinson’s.

Engineers Can Now Wirelessly Hack Your Car

It wasn’t too surprising when scientists first hacked into a car using its own onboard diagnostic port—sure, it’s easy to get into a car’s electronic brain if you’re already inside the car. Now the science of car-hacking has received a digital upgrade: Researchers have have gained access to modern, electronics-riddled cars from the outside. And in so doing, they’ve managed to take control of a car’s door locks, dashboard displays, and even its brakes.
The oddest part of these findings, which were presented this week to the National Academy of Science’s Committee on Electronic Vehicle Controls and Unintended Acceleration, is that they weren’t entirely intentional: It was all part of an investigation prompted by the Toyota acceleration problems, and was meant to probe the safety of electronic automotive systems. But testing those system’s safety also uncovered some flaws.
How It Works
The researchers took a 2009 sedan (they declined to identify the make and embarrass the manufacturer) and methodically tried to hack into it using every trick they could think of. They discovered a couple good ones.
News Roundup: Japan Nuclear Fears, Sperm-Whale Names, Internet on Steroids
Japan update: Authorities have been having trouble keeping enough water around Fukushima Daiichi’s nuclear fuel rods, leading Chief Cabinet Secretary Yukio Edano to respond, when asked whether they were melting: “Although we cannot directly check it, it’s highly likely happening.” Still, radiation levels remain at “tolerable levels.”- Call me Ishmael: Slight variations in sperm-whale calls may act as “whale names,” or personal identifiers that allow these social creatures to tell individuals apart.
- Star wars turns to trash: NASA is looking to create a cheap, ground-based laser that would be capable of blasting (ok, slightly nudging, slowing down, and de-orbiting) Earth-orbiting space junk in danger of crashing.
Robots That Talk Like Cave-Dwelling Crickets: Using Silent Puffs Of Air
Ant trails, airborne chemicals, wood vibrations—scientists have a long history of borrowing clever communication techniques from the animal kingdom. Inspired by the odd social habits of a cave-dwelling cricket, scientists have now taught robots to communicate by firing rings of pressurized air at each other.
The cricket in question is the African cave cricket (Phaeophilacris spectrum), which rapidly flicks its wings to launch donut-shaped air rings, a type of vortex, to both potential mates and enemies. Reduced to two kinds of messages, its “language” is pretty simple: It sends isolated vortices to threaten its rival, and a rapid sequence of vortices to woo would-be lovers.
When Andy Russell, an engineer at Monash University in Australia, learned about the cricket, he thought this technique would improve robots’ ability to communicate in noisy environments—but that wasn’t the only benefit. “Like the cave crickets, there may be times when a robot does not want its communications intercepted,” Russell told New Scientist. Researchers speculate that the cricket uses vortices to communicate undetected by predators—so why not robots? Chris Melhuish, a researcher at the Bristol Robotics Laboratory in the UK said, “This could be a useful addition to the communication armoury of future robotic systems.”
So, Did Tech-Lovers Get What They Wanted With Apple’s iPad 2?

Tech bloggers can relax those fingers and recover from endurance live-blogging: The iPad 2 has been revealed by the turtlenecked wonder himself, Steve Jobs. Now that the world has had a look at the next-gen tablet, do its improvements satisfy the wants of the computing masses?
No surprise, the specs are impressive. Apple’s iPad 2 is one-third skinnier and 0.2 pounds lighter than its predecessor. It boasts cameras on both the front and the back, and a video camera which can sync up with iPhones for video chat. It has a 1GHz dual core processor but maintains the 10-hour battery life of the original. The base price is the same, $499, and it goes on sale in the U.S. on March 11. And yes, the rumors are true: It’s coming out in white as well as black.
The toys aren’t bad, either. The new version of iPad’s operating system includes Photo Booth, the standby application for taking gratuitous photos of yourself and mutilating them in new and interesting ways. The app iMovie—which has long been on Apple laptops—is on iPad now, too, allowing users edit film on the tablet. And Jobs gleefully spent much of the presentation fiddling with the iPad version of Apple’s music creation program, Garage Band.
You can play a piano on the iPad, as well as a whole mess of other instruments. There’s a button for a sustain pedal, and the virtual keys are touch sensitive. Play a key softly, the sound is soft. Play it hard, and the sound changes. The iPad uses its accelerometer to measure the force with which the keys are struck. [The New York Times live blog]
“What Is Champion?” IBM’s Watson Seals Its Jeopardy Victory

The scores (and the facial expressions of the beleaguered humans) say it all: Last night on Jeopardy, IBM’s Watson supercomputer completed its dominating victory over former champs Ken Jennings and Brad Rutter. The carbon-based life forms managed a few correct answers during the final game of the three-day match, but not nearly enough to overcome Watson’s smarts and speed.
Facing certain defeat at the hands of a room-size IBM computer on Wednesday evening, Ken Jennings, famous for winning 74 games in a row on the TV quiz show, acknowledged the obvious. “I, for one, welcome our new computer overlords,” he wrote on his video screen. [The New York Times]
Jennings, who spent much of the three-day extravaganza grimacing with frustration at not being able to buzz in ahead of Watson, wrote up his experiences for Slate today. Once the machine acquired the human skill of parsing Jeopardy questions, he writes, there was really no stopping it. If Watson knew the correct response, it was going to ring in first.
