West Nile virus can infect a wide range of animals, but only a few key species of bird "hosts" and mosquito "vectors" are important in transmission of the virus, according to an article published in Science.  West Nile virus spread across the United States in just a few years after its initial appearance in New York in 1999.  The virus is now well established throu

A new malaria vaccine provided significant protection against malaria in African children, according to a clinical trial report published in the New England Journal of Medicine. This could be the first effective vaccine against malaria.

A six-legged robotic bug, DASH, outfitted with wings to improve its mobility unexpectedly shed some light on the evolution of flight.

A research group has now, for the first time, visualized the motion of electrons during a chemical reaction. The new findings in the experiment are of fundamental importance for photochemistry and could also assist the design of more efficient solar cells.

A team of scientists have invented new artificial muscles strong enough to rotate objects a thousand times their own weight, but with the same flexibility of an elephant’s trunk or octopus limbs.  The new twisting artificial muscle could be used for propelling nano robots.

Taking considerable risk  male crickets remain with their female partners, postcopulation, to protect them.  This behavior has generally been interpreted as a guarding tactic of male crickets designed to reduce the likelihood that a rival male can rapidly displace the ejaculate of the guarding male.

Neuroscientists have discovered a novel response to human faces by looking at recordings from brain cells in neurosurgical patients. The finding provides the first description of neurons that respond strongly when the patient sees an entire face, but respond much less to a face in which only a very small region has been erased.
