U-M scientists simulate effects of blowing Mars dust

Gusting winds and the pulsating exhaust plumes from the Phoenix spacecraft's landing engines could complicate NASA's efforts to sample frozen soil from the surface of Mars, according to University of Michigan atmospheric scientist Nilton Renno.

1. Health effects of pesticide mixtures: Unexpected insights from the salmon brain
   02-16-2008 · EurekAlert!
   In his research, NOAA scientist Nat Scholz examines how pesticides that run off the land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system. These pesticides are widely used in the United States and their occurrence as mixtures in the food supply for humans may also pose an unexpected risk for people.

2. Arizona State scientists keep an eye on Martian dust storm
   07-11-2007 · EurekAlert!
   Scientists at Arizona State University's Mars Space Flight Center are using the Thermal Emission Imaging System (THEMIS) on NASA's Mars Odyssey orbiter to monitor a large dust storm on the Red Planet. The dust storm, which erupted during the last week of June 2007, is affecting operations for all five spacecraft operating at Mars: two NASA rovers on the ground plus three orbiters, two of which belong to NASA and one to the European Space Agency.

3. U of M physicist reads the history of the solar system in grains of comet dust
   01-03-2008 · EurekAlert!
   Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin. After testing helium and neon trapped in the dust specks, Pepin and his colleagues report that while the comet formed in the icy fringes of the solar system, the dust appears to have been born close to the infant sun.

4. The key to quieter Atlantic hurricane seasons may be blowing in the wind
   02-15-2008 · EurekAlert!
   Every year, storms over West Africa disturb millions of tons of dust and strong winds carry those particles into the skies over the Atlantic. According to a recent study led by University of Wisconsin-Madison atmospheric scientists, this dust from Africa directly affects ocean temperature, a key ingredient in Atlantic hurricane development.

5. Arizona State University scientist finds Martian ice is patchy and variable
   05-02-2007 · EurekAlert!
   For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.

   Scientists have discovered that reducing calorie intake later in life can still induce many of the health and longevity benefits of life-long calorie reduction. Importantly, this also includes anti-cancer effects. They are using this knowledge to establish a novel screening technique to find drugs which mimic this longevity effect.
