A bird banking in a crosswind doesn't rely on spinning blades. Its wings flex, twist and respond instantly to its environment. Engineers at Rutgers University have taken a major step toward building bird-like drones that move the same way, flapping their wings like real birds, using electricity-driven materials instead of conventional electromagnetic motors to power them.

When a nuclear plant reaches the end of its life or is damaged, it must be decommissioned. This process can take more than 20 years and includes decontamination, dismantling, and handling radioactive materials so the site can be reused. According to the International Atomic Energy Agency, almost half of the 423 nuclear power reactors in operation today are expected to enter decommissioning by 2050.

A collaborative research group has developed a bio-inspired robotic system based on insect behavior which can locate odor sources both indoors and outdoors with consistent accuracy, even if one of its two sensors fails. The team includes Assistant Professor Shigaki Shunsuke of the National Institute of Informatics (NII), Professor Kurabayashi Daisuke of the School of Engineering at Science Tokyo, and Associate Professor Owaki Dai of the Graduate School of Engineering at Tohoku University.
