Increasing Dust Accelerates Mountain Snowmelt
June 30, 2009 07:34 AM - Discovery News from AP

Dust in the wind is rewriting the cycle of life in the mountains. Throughout memory the warmth of spring has begun the mountain snowmelt, bringing life-giving water to greening plants so they can blossom and renew their species. But now, scientists say, the timing is being thrown off by desert dust stirred as global warming dries larger areas and human activity increases in those regions.

Dams Are Thwarting Louisiana Marsh Restoration, Study Says

Desperate to halt the erosion of Louisiana’s coast, officials there are talking about breaking Mississippi River levees south of New Orleans to restore the nourishing flow of muddy water into the state’s marshes.

NASA readies 'sandbox' to plot Mars rover's escape
June 23, 2009 03:15 PM - Rachel Courtland, New Scientist

NASA plans to fill a 'sandbox' with simulated Martian soil this week to test escape maneuvers for the Mars rover Spirit, which has been stuck in a sand trap called "Troy" since early May. When the rover first became stuck, its wheels slipped so much in the fine, flour-like soil that Spirit moved just centimeters despite the fact that its wheels had rotated enough to move it about 10 metres away. Mission managers then stopped trying to drive the rover, whose wheels had already become buried halfway into the loose soil.
