How to program unreliable chips

As transistors get smaller, they also become less reliable. So far, computer-chip designers have been able to work around that problem, but in the future, it could mean that computers stop improving at the rate we've come ...

Hip-hip-Hadoop: Data mining for science

The model of distributed calculations, where a problem is broken down into distinct parts that can be solved individually on a computer and then recombined, has been around for decades. Divide-and-conquer techniques allow ...

Under the hood of the ribosome

(Phys.org) —We all know—generally speaking—how a car works: The gas pedal makes it go, the break pedal makes it stop, and the steering wheel determines its course. But pop open the hood and you'll find there's a lot ...

More efficient and reliable robotic-control systems

When a robot is moving one of its limbs through free space, its behavior is well-described by a few simple equations. But as soon as it strikes something solid—when a walking robot's foot hits the ground, or a grasping ...
