Video games like Dance Dance Revolution could soon require more than just fancy footwork.

Small, cheap sensors for tracking the movement of a person's entire body could lead to "whole-body interfaces" for controlling computers or playing games, researchers say.

In the middle of rush hour on Aug. 1, at 6:04 p.m., traffic zoomed across the westbound span of the I-35 Mississippi River bridge in Minneapolis.

By 6:05, the 40-year-old structure had buckled and broken, dumping most of the bridge into the river and killing 13 people. Though it came as a shock, this was in retrospect an accident waiting to happen, experts say. The Minneapolis bridge had been poorly maintained, with cracks in its iron arches that had been patched up over the years. And the bridge's design lacked redundancy.

Researchers have hit upon an unusual way to spin tiny propellers – set them on top of tiny bouncing bubbles.

Inspired by winged seed pods, they could find use for mixing tiny amounts of liquids, or strength-testing nanostructures, researchers say.

A long-sought device able to produce a beam of 'T-rays' that could revolutionise airport security and medical scans has been created by persuading normally independent quantum junctions to work together.

Carbon nanotubes spun to form long yarnlike fibers could outperform even the strongest bullet-proof materials on the market, but turning nanotubes into such materials has proved to be a challenge.

Now researchers say that they have improved the method of making the fibers: they can pull them from a hot furnace faster, make the nanotubes line up better, and vastly improve their strength.

It takes only a tiny magnetic field to see clear through a person's head, a new study shows.

A method called ultra-low field magnetic resonance imaging (MRI) has captured its first, blurry shots of a human brain, revealing activity as well as structure.

A new microbe-powered device can extract up to 99% of the available hydrogen from biological compounds that have stumped previous attempts to ferment fuel from plant waste.

The secret is to give the bugs a helping hand with a kick of electric charge.

The most energetic particles in the universe shoot from supermassive black holes at the centers of galaxies, a new study suggests.

Particles known as cosmic rays are constantly bombarding objects in space. The sun bathes Earth in low-energy cosmic rays, astronomers have found, and exploding stars emit medium-energy particles.

MicroRNAs may be only short snippets of nucleic acid, but since their discovery more than a decade ago, biologists—many of them in Boston—have uncovered the important roles these molecules play in orchestrating some of the most basic processes in cells, such as cell division and differentiation.

So it’s not surprising that these gene-regulating molecules are turning out to be central to the development of cancer. “The interplay between microRNAs and cancer is enormous,” says Carl Novina, a microRNA researcher at the Dana-Farber Cancer Institute.

Computers might not be clever enough to trick adults into thinking they are intelligent yet, but a new study shows that a giggling robot is sophisticated enough to get toddlers to treat it as a peer.

An experiment led by Javier Movellan at the University of California San Diego, US, is the first long-term study of interaction between toddlers and robots.
