The contented shall inherit the Earth—The glum? Not so much

The survival of the fittest might just be the survival of the steadfast instead. Having a positive attitude could be evolutionarily advantageous, according to Cornell researchers who simulated generations of evolution in ...

Simulations aimed at safer transport of explosives

In 2005, a semi truck hauling 35,000 pounds of explosives through the Spanish Fork Canyon in Utah crashed and caught fire, causing a dramatic explosion that left a 30- by-70-foot crater in the highway.

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 ...

How computers can learn better

Reinforcement learning is a technique, common in computer science, in which a computer system learns how best to solve some problem through trial-and-error. Classic applications of reinforcement learning involve problems ...

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 ...
