Remote-controlled cockroach swarm can now breathe underwater

Tiny 3D-printed suits let cockroaches walk underwater for hours without harm, creating a potential swarm of cyborg insects. This could help explore disaster zones and even Mars, offering a new way to gather critical information. The breakthrough shows how technology can adapt nature for human benefit.
Tiny 3D-printed diving suits allow cockroaches to walk underwater for up to 3 hours with no ill effects, which could enable a cyborg insect swarm to explore disaster zones and perhaps even Mars
