Airborne dust causes ripple effect on climate far away
01-29-2007 · EurekAlert!When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters. NASA researchers have found a similar process at work in the atmosphere: tiny particles in the air called aerosols can cause a rippling effect on the climate thousands of miles away from their source region.

- Scientists to track impact of Asian dust and pollution on clouds, weather, climate change
04-18-2007 · EurekAlert!
Scientists using the nation's newest and most capable aircraft for environmental research are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. The plumes are believed to affect weather systems and global climate.

Scientists using one of the nation's newest and most capable research aircraft are launching a far-reaching field project this month to study plumes of airborne dust and pollutants that originate in Asia and journey to North America. The plumes are among the largest such events on Earth, so great in scope that scientists believe they might affect clouds and weather across thousands of miles while interacting with the sun's radiation and playing a role in global climate.

- New theory for mass extinctions
10-24-2006 · EurekAlert!
A new theory on just what causes Earth's worst mass extinctions may help settle the endless scientific dust-up on the matter. Whether you favor meteor impacts, volcanic eruptions, cosmic rays, epidemics or some other cause for the worst mass extinction events in Earth's history, no single cause has ever satisfied all scientists all the time for any extinction event. That may be because big extinctions aren't simple events.

- Dung happens and helps scientists
02-15-2008 · EurekAlert!
A scientist at Northern Arizona University is in charge of the largest animal dung collection in the world, used for clues about animal evolution and extinction, Ice Age existence and climate change. Researcher Jim Mead admits it is a bizarre resource, but he is one of many around the globe who access dung for DNA information. Mead, a dung authority, continues to grow the collection with specimens from as far away as Siberia.

- Electric sand findings could lead to better climate models
01-07-2008 · EurekAlert!
Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. The other culprit is electricity. By taking both factors into account, researchers at the University of Michigan have developed a new model that matches real-world measurements of "saltation" better than the decades-old classical theory.

- If air gets scarce -- new gene causes asthma in children
08-20-2007 · EurekAlert!
Usually harmless external stimuli like animal hair, pollen and house dust cause a life-endangering narrowing of the bronchi in asthma patients. An international team of scientists headed by researchers from the Ludwig-Maximilians University, Munich, and Oxford University, UK, have now been able to identify a gene that clearly increases the risk for asthma in childhood.
