NASA Ozone Study May Benefit Air Standards, Climate

PASADENA, Calif. – A new NASA-led study finds that when it comes to combating global warming caused by emissions of ozone-forming chemicals, location matters.

Ozone is both a major air pollutant with known adverse health effects and a greenhouse gas that traps heat from escaping Earth’s atmosphere. Scientists and policy analysts are interested in learning how curbing the emissions of these chemicals can improve human health and also help mitigate climate change. (more…)

Nitrogen Pollution Changing Rocky Mountain National Park Vegetation, Says CU-Boulder Study

A new study led by the University of Colorado Boulder indicates air pollution in the form of nitrogen compounds emanating from power plants, automobiles and agriculture is changing the alpine vegetation in Rocky Mountain National Park.

The emissions of nitrogen compounds to the atmosphere are being carried to remote areas of the park, altering sensitive ecosystems, said CU-Boulder Professor William Bowman, who directs CU-Boulder’s Mountain Research Station west of Boulder and who led the study. “The changes are subtle, but important,” he said. “They represent a first step in a series of changes which may be relatively irreversible.”

In other regions of the world, higher amounts of nitrogen pollutants correlate with decreased biodiversity, acidified soils and dead stream organisms like trout, said Bowman. “There is evidence that indicates once these changes occur, they can be difficult if not impossible to reverse. It is best to recognize these early stages before the more harmful later stages happen.” (more…)

Researchers Reap a Sweet and Sustainable Harvest

*Known as the sugarcane of the desert, sweet sorghum could be a sustainable and ecological future biofuel crop for Arizona.*

Researchers in the University of Arizona’s department of agricultural and biosystems engineering recently reaped the reward of six years of planning, testing and trials and harvested 40 acres of experimental sweet sorghum at the UA College of Agriculture and Life Sciences’ Red Rock Agricultural Research Center.

Known as the sugarcane of the desert, sweet sorghum could be a sustainable and ecological future biofuel crop for Arizona – and there will be one, said Dennis Ray, a plant geneticist in the UA’s College of Agriculture and Life Sciences: “There’s no doubt that we’re going to have biofuels in the future because no matter what, petroleum is a finite resource.” (more…)

Imagine: Material That If Scratched, You Can Quickly and Easily Fix Yourself, With Light Not Heat

*Discovery of self-corrective healing process for polymer detailed this week in the journal Nature*

Imagine you’re driving your own new car–or a rental car–and you need to park in a commercial garage. Maybe you’re going to work, visiting a mall or attending an event at a sports stadium, and you’re in a rush. Limited and small available spots and concrete pillars make parking a challenge. And it happens that day: you slightly misjudge a corner and you can hear the squeal as you scratch the side of your car–small scratches, but large anticipated repair costs.

Now imagine that that you can repair these unsightly scratches yourself–quickly, easily and inexpensively–or that you can go through a car wash that can detect these and other more minor scratches and fix them as the car goes through the washing garage. Fantasy. Not exactly. Not anymore. Not according to a new discovery detailed in the April 21 issue of the journal Nature, and depicted in a short video interview and simulation. (more…)
