|A high-tech robotic fish hatched at Michigan State University has a new look. A new skill. And a new name. MSU scientists have made a number of improvements on the fish, including the ability to glide long distances, which is the most important change to date. ...> Full Article|
|Nanyang Technological University scientists have invented a 'sense-ational' device, similar to a string of 'feelers' found on the bodies of the blind cave fish, which enables the fish to 'sense' their surrounding and so navigate easily. ...> Full Article|
|Polytechnic Institute of New York University researchers have published findings in the Journal of the Royal Society Interface that illuminate the emerging field of ethorobotics -- the study of bioinspired robots interacting with animal counterparts. They studied how real-time feedback attracted or repelled live zebrafish. The fish were more attracted to robots with tail motions that mimicked the live fish. The researchers hope that robots eventually may steer live animal or marine groups from danger. ...> Full Article|
|Homeland Security's BIOSwimmer? is a unmanned underwater vehicle designed for high maneuverability in harsh environments and hard-to-reach underwater places where inspection and security is necessary. ...> Full Article|
A bioinspired robot has provided the first experimental evidence that live zebrafish can be influenced by engineered robots.

Shark skin has long been known to improve the fish's swimming performance by reducing drag, but now George Lauder and Johannes Oeffner from Harvard University show that in addition, the skin generates thrust, giving the fish an extra boost. The duo also discovered that Speedo's shark skin-inspired Fastskin® FS II fabric surface does not improve swimming speed, although they point out that the figure hugging costumes probably enhance performance in other ways.

|Scientists at the University of Maryland and Tulane University have developed a computational model of a swimming fish that is the first to address the interaction of internal and external forces on locomotion. The research team simulated how the fish's body bends, depending on the forces from the fluid moving around it as well as the muscles inside. Understanding these interactions will help design medical prosthetics for humans that work with the body's natural mechanics. ...> Full Article|
|How well do flying fish fly? This is the question that puzzled Haecheon Choi from Seoul National University, Korea. Measuring aerodynamic forces on dried darkedged-wing flying fish in a wind tunnel, Choi and Hyungmin Park discovered that flying fish glide better than insects and as well as birds. The fish also derive an aerodynamic advantage from gliding close to the water's surface to cover distances as great as 400 meters. ...> Full Article|
Civil Engineering Professor Bill Yu has built a pair of sensors to provide real-time risk assessments of bridges during flooding -- the largest cause by far of bridge failure.

|To lower the fuel consumption of airplanes and ships, it is necessary to reduce their flow resistance, or drag. An innovative paint system makes this possible. This not only lowers costs, it also reduces CO2 emissions. ...> Full Article|
|The quest to derive energy from wind may soon be getting some help from Caltech fluid-dynamics expert John Dabiri -- and a school of fish. ...> Full Article|
|The fish species Astyanax fasciatus cannot see, but their unique technique for sensing their environment and the movement of water around them with gel-covered hairs that extend from their bodies may inspire a new generation of sensors that perform better than current active sonar. ...> Full Article|
|Scientists seeking to protect the soldier of the future can learn a lot from a relic of the past ...> Full Article|
|Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines. ...> Full Article||
