Neither sun, nor mud, nor atypically warm March weather in northern Michigan could keep three hardy entries from completing the Endurance Run at the 2010 SAE Clean Snowmobile Challenge at Michigan Technological University. Making it through the course were North Dakota State University, the University of Wisconsin-Madison and the University of Minnesota-Duluth.

The Clean Snowmobile Challenge is a collegiate design competition of the Society of Automotive Engineers. Engineering students from participating schools take a stock snowmobile and reengineer it. Their aim: to reduce emissions and noise while maintaining or boosting performance.

The Challenge includes a zero emissions division for battery-powered sleds. Michigan Tech’s Keweenaw Research Center co-hosts the event with the Department of Mechanical Engineering-Engineering Mechanics.

During the Endurance Run, entries in the Challenge’s zero emissions division competed in a range test and were judged by how far their battery-powered snowmobiles could travel. Clarkson University went 10 miles, the farthest on a single charge, followed by McGill University in second. Wisconsin-Madison's zero emissions entry was third followed by South Dakota School of Mines and Technology, fourth.

The theme for the internal combustion engine division this year is fuel economy. “After10 years of hosting the Challenge, we know we can beat industry emission standards,” said co-organizer Jay Meldrum, director of Michigan Tech’s Keweenaw Research Center. “Now we want to improve fuel economy using E2X.”

E2X is a gasoline-ethanol blend incorporating 20 to 29 percent ethanol.

Cold and Bubbly: The Sensory Qualities that Best Quench Thirst

New research from the Monell Center finds that oral perceptions of coldness and carbonation help to reduce thirst. The findings could guide sensory approaches to increase fluid intake in populations at risk for dehydration, including the elderly, soldiers, and athletes.

J.R. Macdonald Lab receives nearly $8 million DOE grant renewal

MANHATTAN -- A nearly $8 million grant from the U.S. Department of Energy is supporting the "bread and butter" physics research at Kansas State University's James R. Macdonald Laboratory. The grant is a three-year renewal award, "Structure and Dynamics of Atoms, Ions, Molecules and Surfaces." "This big operational grant is our bread-and-butter," said Itzik Ben-Itzhak, university distinguished professor of physics and director of the J.
