Pupil Dilation Marks Decision Making

The eyes may be the windows to the soul, but the simple pupil--the circular opening at the center of the eye that contracts and dilates to regulate the amount of light the eye receives--offers a remarkable portal to the inner ...

Titan's surface organics surpass oil reserves on Earth

Saturn’s orange moon Titan has hundreds of times more liquid hydrocarbons than all the known oil and natural gas reserves on Earth, according to new Cassini data. The hydrocarbons rain from the sky, collecting in vast deposits ...

Predicting the perfect predator

Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. University of Illinois ecologist Adam Davis has ...

Remarkable new nano-fiber clothing may someday power your iPod

Nanotechnology researchers are developing the perfect complement to the power tie: a “power shirt” able to generate electricity to power small electronic devices for soldiers in the field, hikers and others whose physical ...

Cheating is easy -- for the social amoeba

Cheating is easy and seemingly without cost for the social amoeba known as Dictyostelium discoideum, said a team of researchers from Baylor College of Medicine and Rice University in Houston who conducted the first genome-scale ...

Possible progenitor of special supernova type detected

Using data from NASA's Chandra X-ray Observatory, scientists have reported the possible detection of a binary star system that was later destroyed in a supernova explosion. The new method they used provides great future ...

Graphene Holds Promise for Spintronics

Graphene is a nanomaterial which combines a very simple atomic structure with intriguingly complex and largely unexplored physics. Since its first isolation about four years ago, researchers suggest a large number of applications ...

'Genetic corridors' are next step to saving tigers

The Wildlife Conservation Society and the Panthera Foundation announced plans to establish a 5,000 mile-long “genetic corridor” from Bhutan to Burma that would allow tiger populations to roam freely across landscapes. ...
