Chickens Finally 'One-Up' Humans

COLBY, Kan. - Birds, reptiles and mammals are all descended from a common ancestor, but during the age of the dinosaurs, most mammals became nocturnal for millions of years. Birds likely owe their superior color vision to not having spent a period of evolutionary history in the dark.

"Birds have clearly one-upped us in several ways in terms of color vision," says Joseph C. Corbo, M.D., Ph.D., senior author and assistant professor of pathology and immunology and of genetics at the Washington University School of Medicine in St. Louis.

According to Corbo, researchers have peered deep into the eye of the chicken and found a masterpiece of biological design.

HAYS, Kan. - Rising temperatures, faster evaporation rates, and more sustained drought brought on by climate change will bring stress to water resources and particularly our wetlands. Climate change is likely to affect native plant and animal species by altering key habitats such as the wetland ecosystems known as prairie potholes or playa lakes.

The new research shows that the prairies will be much more sensitive to climate warming and drying than previously thought.

COLBY, Kan. - White roofs can have the effect of cooling temperatures within buildings. As a result, depending on the local climate, the amount of energy used for space heating and air conditioning could change, which could affect both outside air temperatures and the consumption of fossil fuels such as oil and coal that are associated with global warming.

Depending on whether air conditioning or heating is affected more, this could either magnify or partially offset the impact of the roofs.

White roofs would reflect some of that heat back into space and cool temperatures, much as wearing a white shirt on a sunny day can be cooler than wearing a dark shirt.

Moreover, painting the roofs of buildings white has the potential to significantly cool cities and mitigate some impacts of global warming, a new study indicates.
