Squid And Zebrafish Spark Camouflage Inspiration
2012-05-04 04:59:16

University of Bristol researchers have created artificial muscles that can be transformed to mimic the camouflaging abilities of squid and zebrafish. The team demonstrated two individual transforming mechanisms that they believe could be used in "smart clothing" to trigger camouflaging tricks similar to animals observed in the wild. "We have taken inspiration from nature's designs and exploited the same methods to turn our artificial muscles into striking visual effects,"  Jonathan...

Researchers from the University of Bristol have created artificial muscles that can be transformed at the flick of a switch to mimic the remarkable camouflaging abilities of organisms such as squid and zebrafish. They demonstrate two individual transforming mechanisms that they believe could be used in 'smart clothing' to trigger camouflaging tricks similar to those seen in nature. The study is published today, 2 May, in IOP Publishing's journal Bioinspiration and Biomimetics, and is...

For treatment of vocal fold disorders, UD researchers look to insect protein A one-inch long grasshopper can leap a distance of about 20 inches. Cicadas can produce sound at about the same frequency as radio waves. Fleas measuring only millimeters can jump an astonishing 100 times their height in microseconds. How do they do it? They make use of a naturally occurring protein called resilin. Resilin is a protein in the composite structures found in the leg and wing joints, and sound...

What Makes A Robot Fish Attractive?
2012-03-02 04:41:26

Probing the largely unexplored question of what characteristics make a leader among schooling fish, researchers have discovered that by mimicking nature, a robotic fish can transform into a leader of live ones. Through a series of experiments, researchers from Polytechnic Institute of New York University (NYU-Poly) aimed to increase understanding of collective animal behavior, including learning how robots might someday steer fish away from environmental disasters. Nature is a growing...

It´s a matchup worthy of a late-night cable movie: put a school of starving piranha and a 300-pound fish together, and who comes out the winner? The surprising answer–given the notorious guillotine-like bite of the piranha–is Brazil´s massive Arapaima fish. The secret to Arapaima´s success lie in its intricately designed scales, which could provide “bioinspiration” for engineers looking to develop flexible ceramics. The inspiration for this study...

Bionic Leg Makes Amputee Faster On His Feet

[ Watch the Video ] This powered prosthetic is better at anticipating the next move Craig Hutto considers himself part bionic man. In 2005, doctors amputated his leg after a shark attacked him during a fishing trip off the Florida Gulf Coast. "I was 16 years old at the time," recalls Hutto. "My brother heard me yell: 'What was that?' He saw something take me under; he saw the back fin of the shark. There was so much tissue damage and so much flesh gone that it was just irreparable."...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
