Explained: How does a soccer ball swerve?

The smoothness of a ball’s surface — in addition to playing technique — is a critical factor. It happens every four years: The World Cup begins and some of the world’s most skilled players carefully […]
This scanning electron microscope image shows ultrafine diamond needles (cone shapes rising from bottom) being pushed on by a diamond tip (dark shape at top). These images reveal that the diamond needles can bend as much as 9 percent and still return to their original shape.

How to bend and stretch a diamond

The brittle material can turn flexible when made into ultrafine needles, researchers find. Diamond is well-known as the strongest of all natural materials, and with that strength comes another tightly linked property: brittleness. But now, […]
“We are particularly interested in wetsuits for surfing, where the athlete moves frequently between air and water environments,” says Anette (Peko) Hosoi, a professor of mechanical engineering and associate head of the department at MIT. “We can control the length, spacing, and arrangement of hairs, which allows us to design textures to match certain dive speeds and maximize the wetsuit's dry region.”

Beaver-inspired wetsuits in the works

Rubbery hair-lined wetsuits may help keep surfers warm. Beavers and sea otters lack the thick layer of blubber that insulates walruses and whales. And yet these small, semiaquatic mammals can keep warm and even dry […]
MIT researchers have developed a new platform for microfluidics, using LEGO bricks. Shown here, fluid flows through tiny channels milled into the side walls of LEGO bricks.

Human tissue samples linked by microfluidic channels replicate interactions of multiple organs. MIT engineers have developed new technology that could be used to evaluate new drugs and detect possible side effects before the drugs are […]
In a time-lapse sequence, infrared imaging shows the temperature changes within a droplet of water as it moves across a treated silicon surface in response to temperature differences on that surface.
