Cornell professor of biological and environmental engineering Dan Luo and research associate Shogo Hamada have created a DNA material capable of metabolism, in addition to self-assembly and organization.

Autonomous submersible craft could harvest a species that is damaging critical reefs and depleting valuable fish supplies.

Recently, engineers and marine biologists at the University of California have developed an eel-like robot which can swim silently in salt water without the use of an electric motor. Instead, the robot uses artificial muscles that fill with water to propel itself. The foot-long robot, which is connected to an electronics board that remains on the surface of the water, is also virtually transparent.
