Scientists discover hidden symmetries, opening new avenues for material design

When you knock on a melon to see if it's ripe, you are using sound waves to probe the structure of the material inside. Physicists at the University of Chicago were using the same concept to explore how sound waves travel ...

Using a material's 'memory' to encode unique physical properties

A new study published in Science Advances found that certain types of materials have a "memory" of how they were processed, stored, and manipulated. Researchers were then able to use this memory to control how a material ...
