In the second-season premiere, Hawking and his team investigate groundbreaking innovations in science inspired by nature. Included are reports on all-terrain robots designed to go where humans and vehicles can't; underwater subs used to train astronauts for deep-space exploration; a fabric that mimics the adhesive ability of gecko feet; the process of reengineering a virus to prevent pandemics; and the realization of Nikola Tesla's dream of wireless power.
Examining how science is adapting and reinventing itself. Included: advanced quadrocopters that work in unison to perform astonishing feats; and a blood-clotting product found in bioengineered shrimp shells.
Technology that's transforming the idea of reality is highlighted, including a 3-D virtual training program created for the military. Also: a system that maps locations inaccessible by GPS; and 3-D bioprinting.
A look at inventions that could change how humans deal with crises in the future. Included: a pilotless helicopter; a high-tech bomb disposal robot; and a sniper rifle equipped with jet fighter target tracking technology.
