Snake venom does not sweat for opossums
Pit viper venom is getting podpajeczynówkowy does not sweat for certain species of opossum, which devour snakes with impunity. Now finding Why opossums do not give a hoot about prepare bitten researchers at the University of Minnesota and the American Museum of natural history in New York. Snake venom aimed at important protein clotting of blood, but blood clotter opossums is chemically modified and penetrated the toxin molecular clutch, researchers report online on June 22 in PLoS ONE. Another retro, which eat snakes, such as the honey forest, mongooses and kune Desert, have different ideas for rozbrajania toxins, suggesting that strategies are themselves responsible for antivenom has evolved, since many times in animals. – Rachel Ehrenberg
Flexible screen
The scientists created a prototype of an electronic display screen, which is thinner than a dime, and can be folded up like a piece of paper. The device employs a flexible organic light-emitting diodes, color filter and a protective layer that can be made at low temperatures. After 10,000 bends to reduce display brightness was so low was indiscernible to the human eye, scientists from Samsung in Korea and Purdue University in West Lafayette, Ind. report. When you bend deforms liquid crystal display, a new approach may make Paravane literally seamless. The prototype is described online July 7 in advanced materials. – Rachel Ehrenberg
Penguins Smells dinnertime
The smell of death is the dinner of the penguins. African penguins flock for Ocean spots which smell like dimethylsulfide, compound released when the krill and other small floaters meet their doom discovered the scientists in South Africa, from the University of Cape Town. Penguin for the presence of plankton dead or dying, it means that the feast of living fish eat krill in the vicinity. The penguins can track smell their prey food from two miles away, the team reports in the online journal of experimental biology, July 14. – Rachel Ehrenberg
