To study jellyfish and other fragile marine life without damaging them, researchers developed ultra-soft underwater grippers that catch and release jellyfish without harm.

Flying in shallow arcs helps birds stay aloft with less effort.

Engineers predict how flowing fluid will bend tiny hairs that line blood vessels and intestines.

Three-tiered structure of these impact-resistant shells could inspire better helmets, body armor.

A bio-inspired gel material developed at MIT could help engineers control movements of soft robots.
