He was found not guilty of murder after a jury was told the couple's bitter divorce proceedings had placed him under stress.

In an earlier study, researchers showed that some plants emit ultrasonic clicks when under stress.

In materials science, the design could inspire the creation of responsive materials that become stronger under stress, making them ideal for wearable technologies or aerospace applications where durability is critical.

Anisotropy refers to the property of being directionally dependent, such as how wood is stronger along the grain than across it, and viscoelastic materials are both viscous -- like honey, which resists flow and deforms slowly under stress -- and elastic, returning to their original shape when the stress is removed, like rubber.
