Comments Off on Giant manta ray nursery discovered in Gulf of Mexico

Researchers have identified the first recognized giant manta ray nursery in the Flower Garden Banks National Marine Sanctuary in the Gulf of Mexico , about 70 miles offshore from Galveston, Texas . Graduate student and executive director of  Manta Trust Josh Stewart first made this discovery while studying adult mantas in the area for the first time. “I was there trying to get a genetic sample from a full grown manta, and that’s when I saw it. It was a juvenile male manta, which is a very rare,” Stewart told NPR . After expressing his excitement to local researchers, he was informed that young manta sightings were quite common there. He said, “And that’s when I knew that this was a really special, unique place.” The local researchers at the National Oceanic Atmospheric Administration had misidentified the young manta rays as another species, neglecting to recognize the importance of this place until the arrival of an outside perspective. Typically, adult manta rays live in deep tropical and subtropical waters, making the study of these majestic sea creatures quite difficult. Young manta rays are almost never seen with adults. Related: Microplastic pollution poses particular threat to filter-feeding rays, sharks and whales “The juvenile life stage for oceanic mantas has been a bit of a black box for us, since we’re so rarely able to observe them,” Stewart explained. “We don’t know much about their movements, their feeding behavior and how that compares to the adults. Now we have a pool of juveniles that we can study.” The recognition of the nursery will ensure that these young mantas, now an endangered species in the U.S., are protected while also providing a road map for the protection of juvenile habitats around the world. “This research backs up the need for protection of other critical habitat, especially since manta rays have recently been designated as threatened species,” study co-author Michelle Johnston told the Herald Sun . “Threatened species need a safe space to grow up and thrive and live.” + Scripps Institution of Oceanography Via NPR and  The Herald Sun Images via G.P.

Engineers Build Robotic Carp That Can Dive and Turn Like a Real Fish

Comments Off on Engineers Build Robotic Carp That Can Dive and Turn Like a Real Fish

From mechanical manta rays to giant robo jellyfish , the marine world is well represented in the field of robotics. While many autonomous underwater vehicles (AUVs) take advantage of energy-efficient gliding or pulsing motions, a team of scientists at the National University of Singapore’s Department of Electrical and Computer Engineering have invented two robots that mimic the movements of a carp. The machine is capable of diving, floating, and using its fins like a real fish, and it can be maneuvered into spaces that are difficult for many AUVs to access.

Comments Off on NASA’s New X-48C Flying Wing Airplane Uses 50% Less Fuel Than Standard Aircraft

Researchers at NASA have developed a revolutionary flying wing aircraft that uses 50% less fuel than standard planes. The new manta ray-esque X-48C is based on the X-48B Blended Wing Body aircraft , which flew 92 flights at NASA Dryden between 2007 and 2010. The X-48C improves upon its predecessor with its low-noise, fuel-efficient hybrid wing body (HWB) design.

Comments Off on Why Google’s Autonomous Cars Probably Won’t Kill the Auto Industry

It’s undeniable the Google’s autonomous driving tech is pretty awesome—impressive enough that even a blind man can travel behind the wheel of one of the web giant’s self-driving cars. And there’s been a lot of buzz surrounding it, as Google became the first company to gain the legal right to test autonomous cars Nevadan roads, and autonomous cars were recently legalized in California . But, as a recently published editorial by Johann Muller in Forbes discusses, the successes of—and the hype surrounding—Google’s self-driving developments don’t necessarily pose a threat to the conventional auto industry.

There are few more graceful swimmers in the ocean than the ray – ”batiod” rays, such as mantas and stingrays, are quick, agile, and energy-efficient.  Engineers are using these fascinating creatures as inspiration for the Mantabot , a new autonomous underwater vehicle . The Mantabot’s plastic body and and silicone fins are modeled from a direct molding of the cownose ray , and it glides through the water with the same flapping motions as its living counterparts.  Read the rest of Mantabot: University of Virginia Engineers Build a Robot that Looks and Swims Like a Ray Permalink | Add to del.icio.us | digg Post tags: autonomous underwater vehicle , batoid ray , biomimicry , cownose ray , hilary bart-smith , manta ray , mantabot , princeton , ray , stingray , ucla , university of virginia , west chester university
