Improbable video: The net, the flea, the duck and its lover
The net, the flea, the duck and its lover all appear in Improbable Research Collection #101: Our series of tiny bits-and-pieces videos peeks at improbable research — research that makes people laugh, then think. Here, below, is a skimpy guide to these little videos. We might make some more.
Towards a robotic jumping flea (new study)
A South Korean research team, Gwang-Pil Jung and Kyu-Jin Cho, (School of Mechanical and Aerospace Engineering/Institute of Advanced Machines and Design, Seoul National University) and Hong-Cheol Choi (Department of Physics and Chemistry, Korea Military Academy, Seoul) have made progress towards the development of jumping flea robot. “Inspired by the relationship between leg compliance and jumping […]
Flea distributions on stray cats (updated)
“Osbrink and Rust (1985) reported that there was no significant difference in the mean number of fleas collected from any particular area of the cat.” Ref. Osbrink, W.L.A., and M. K. Rust. 1985. Seasonal abundance of adult cat fleas, Ctenocephalides felis (Siphonaptera: Pulicidae) on domestic cats in southern California. Bull Soc Vector Ecol. 1985, 10, […]
Dog & cat flea-jump tribute video
Someone made a tribute video, inspired by the 2008 Ig Nobel physics prize winners. Marie-Christine Cadiergues, Christel Joubert, and Michel Franc of Ecole Nationale Veterinaire de Toulouse, France were honored for discovering that the fleas that live on a dog can jump higher than the fleas that live on a cat.
