Extremely Sophisticated Criminals access Tremendous Amount of IRS Data

May 27, 2015 | by Stephen Ohlemacher, Associated Press | News | Comments

More than 100,000 taxpayers have had their personal tax information stolen from an IRS Web site as part of an elaborate scheme to claim fraudulent tax refunds. The information was stolen from a system called "Get Transcript," where taxpayers can get tax returns and other tax filings from previous years. In order to access the information, the thieves cleared a security screen...

New Algorithm lets Autonomous Robots Divvy up Assembly Tasks on the Fly

May 27, 2015 2:33 pm | by Larry Hardesty, MIT | News | Comments

Today’s industrial robots are remarkably efficient — as long as they’re in a controlled environment where everything is exactly where they expect it to be. But put them in an unfamiliar setting, where they have to think for themselves, and their efficiency plummets. And the difficulty of on-the-fly motion planning increases exponentially with the number of robots involved. For even a simple collaborative task...

Crucial to most designs for quantum computers is quantum error correction, which helps preserve the fragile quantum states on which quantum computation depends. Until now, codes that could make do with limited measurements could correct only a limited number of errors. But now, researchers have presented a new code that can correct errors afflicting - almost - a specified fraction of a computer’s qubits.

Understanding how turbulence can alter the shape and course of a flock of birds, a swarm of insects or even an algal bloom could help us to better predict their impact on the environment. Now mathematicians have investigated for the first time how the surrounding fluid environment – such as air and water - can affect the shape of a model flock.

Although his achievements spanned a huge number of fields in the mathematical sciences, he will likely be best remembered for his work in the development of game theory.

Paralyzed from the neck down after suffering a gunshot wound when he was 21, Erik G. Sorto now can move a robotic arm just by thinking about it and using his imagination. Sorto is the first person in the world to have a neural prosthetic device implanted in a region of the brain where intentions are made, giving him the ability to perform a fluid hand-shaking gesture, drink a beverage and even play “rock, paper, scissors.”

Quantum-mechanical Models Predict New Phase of Matter

Computer simulations have predicted a new phase of matter, an atomically thin two-dimensional liquid. This prediction pushes the boundaries of possible phases of materials further than ever before. Two-dimensional materials themselves were considered impossible until the discovery of graphene around 10 years ago. However, they have been observed only in the solid phase, because the thermal atomic motion required for molten materials...
