In this video excerpt from NOVA's "Making Stuff: Smarter", host and New York Times technology columnist David Pogue visits Virginia Tech, where scientists are developing an artificial jellyfish that ...

ALBUQUERQUE, N.M. — Imagine untwisting a finger-size spring, then holding the flame from a lighter underneath the unraveled section. Like magic, it twirls itself into a spring again because the metal ...

The secret to how steel hardens and shape-memory alloys snap into place lies in rapid, atomic-scale shifts that scientists have struggled to observe in materials. Now, Cornell researchers are ...

Besides superfluous features like touchscreens and internal cameras, basic refrigerator technology hasn't changed much in decades. They still chill your milk by way of chemical refrigerants and ...

What is a shape memory alloy? Shape memory alloys or SMA's are metals that exhibit shape memory properties. The shape memory effect was first discovered in 1932 in a silver-cadmium alloy. It allows ...

Shape-memory alloys that can operate at higher temperatures have been developed by researchers at Texas A&M University, potentially paving the way for the use of the smart materials inside turbine ...

Shape memory alloys (SMA) remember their original shape and return to it after being heated. Similar to how a liquid transforms into a gas when boiled, SMAs undergo a phase transformation when heated ...

Shape memory materials (SMMs) are featured by the ability to recover their original shape from a significant and seemingly plastic deformation upon a particular stimulus is applied 1. This is known as ...

Engineers are closing in on a long imagined goal in aviation, wings that can subtly change shape in midair instead of relying ...

Some metal alloys will "remember" a shape when you heat them to the same temperature they were originally shaped at. So a straight wire made from one of these "shape memory alloys" might change back ...
