Watching Electrons In Molecules During A Chemical Reaction

in technology

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.

Ultra-Strong, Flexible Carbon Nanotube Artificial Muscle Invented

in technology, medicine

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.

Male Crickets Guard Their Females After Mating -The Altruism Among Crickets?

in biology

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.

Neuronal Output Of Emotions - Neural Basis Of Face Recognition

in medicine, biology

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.

How Sugar Boosted Disease Protection And Human Evolution

in biology

Researchers at the University of California, San Diego School of Medicine say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo.

Graphene 'Big Mac' – the four-layered structure may replace the silicon chip

in technology

Scientists at the University of Manchester  sandwiched two sheets of graphene with another two-dimensional material, boron nitrate and  created the graphene 'Big Mac'. This four-layered structure with graphene could be the key to replacing the silicon chip in computers.

Sandia National Lab To Make Near-Invisible Glitter-Sized Solar Cells

in technology

Sandia National Laboratories researchers are planning to make solar cells of near-invisible dimensions.

Physicists localize 3-D matter waves for first time

in technology

University of Illinois physicists have experimentally demonstrated for the first time how three-dimensional conduction is affected by the defects that plague materials. Understanding these effects is important for many electronics applications.
