redOrbit Staff & Wire Reports - Your Universe Online Marine microbes change swimming directions with a sideways flick of their lone flagellum, a type of high-speed controlled failure first documented in 2011 as a unique swimming stroke but whose underlying mechanism had eluded researchers until now. Bacteria swim by rotating the helical, hair-like flagella that extend from their unicellular bodies. Some bacteria, such as the Escherichia coli (E. coli) living in the human gut, have...

Motivated by the desire to determine the simplest 3-D structure that could take advantage of mechanical instability to collapse reversibly, a group of engineers at MIT and Harvard University were stymied – until one of them happened across a collapsible, spherical toy that resembled the structures they'd been exploring, but with a complex layout of 26 solid moving elements and 48 rotating hinges. The toy inspired the engineers to create the "buckliball," a hollow, spherical object...

Biologists and engineers team up to unlock the secret to the hummingbird's 'snap-buckling' beak The shape of a hummingbird's beak allows for a "controlled elastic snap" that allows it to snatch up flying insects in a mere fraction of a second "”with greater speed and power than could be achieved by jaw muscles alone, says a new study in a forthcoming issue of Journal of Theoretical Biology. Hummingbird beaks are built to feed on flowers, but hummingbirds can't live on nectar alone. To...

It's almost one-million pounds of force on the "can," and they want to see it buckle. Watch live TV coverage on NASA Television's Education Channel and the agency's website as NASA engineers test an immense aluminum-lithium rocket fuel tank on Wednesday, March 23, 10:30 a.m. EDT from NASA's Marshall Space Flight Center in Huntsville, Ala. The hope is to use data from the test to generate new "shell-buckling design factors" that will enable lightweight, safe and sturdy "skins" for future...

BLOOMINGTON, Ill., June 26 /PRNewswire/ -- Hot, dry weather is causing roads to buckle, creating hazardous driving conditions. The National Weather Service issued heat warnings across the country this week. Temperatures exceeding 90 degrees over several days can lead to road surfaces buckling with little to no warning. When concrete pavement and concrete pavements overlaid with asphalt expand and push up the pavement surface, it is referred to as buckling. There's not much that can be...
