URI professor investigates the muscle behind blue mussels
The blue mussel clings to life by a thread. Make that about 80 byssal threads in the winter and 30 or so threads in the summer, but you get the idea that life for these hard-shelled mollusks is quite dramatic.

Brain's visual cortex doesn't 'tell' all it knows
New research by scientists at the University of Minnesota and the University of California, San Diego has shown that neurons in the human visual cortex, a brain center that processes visual information, can respond to patterns of lines too fine for subjects to resolve.

Race car drivers dizzy over physics
The drivers competing in the Indianapolis 500 race this weekend will have to contend with more that just the other drivers-they'll have to battle the gravitational forces of physics.

New U. of Colorado research may reduce renewable fuel costs
Researchers at the University of Colorado at Boulder have developed a novel process involving the production of ethanol that could lead to a significant decrease in the cost of renewable fuel.

Duke experiment hints that not much extra carbon dioxide will be locked up in future forests' wood or soils
Results from continuing experiments near Duke University - where forest plots grow in the higher atmospheric levels of carbon dioxide expected by the mid 21st century - suggest that trees and soil may not sop up much of the extra gas over the long term under real-world conditions.

Young children are socialized by their same-sex peers to conform to typical sex role behavior and the effects are noticeable even within a short time, according to a study involving pre-school and kindergarten children.

Soil fertility limits forests capacity to absorb excess CO2.
A field study on the effects of elevated carbon dioxide (CO2) on forest ecosystems raises doubts about the ability of trees to absorb excess CO2 accumulating in the earth's atmosphere.
