SCIENCE OF THE WINTER OLYMPICS: INTERNAL ATHLETE

submitted by: nsf
The United States hasn't won an Olympic medal in cross-country skiing since 1976, but in 2010, several skiers hope to change that. If they're successful, you can be certain it's due to their incredible endurance--cross-country skiers are among the fittest athletes in the world. Deborah King, an associate professor in the Department of Exercise and Sports Sciences at Ithaca College and Joseph Francisco, president of the American Chemical Society, look at the biochemistry of human endurance.

SCIENCE OF SPEED: FIRESUITS

submitted by: nsf

"Frightening" is how Jeff Gordon describes fire, even though he knows he's protected head to toe (and right down to his underwear) by fire-resistant Nomex fabric. Firesuits and the associated gear don't just protect drivers from fire, though--they decrease the rate of heat transfer, giving the driver a little more time to move somewhere cooler.

Getting started with the Ecological Metadata Language

submitted by: LTER_NetworkOffice_is

This short clip shows you how to use Ecological Metadata Language to document your ecological data.
Specifically, it tells you how to download EML, what tools can you use to edit/enter EML metadata, and as an example, it shows how you would use oXygen to create a simple EML document, that is, a metadata record with very basic info such as a title, an abstract, contact info for the organization owning the data set and the point of contact information.

Reconstructing Asian Monsoon History from Chinese Speleothems; Kathleen R. Johnson, Department of Earth System Science, University of California, Irvine: While we know that modern anthropogenic climate change is superimposed upon significant natural climate variability, the instrumental record of climate is too short to capture the full range of this variability. In order to fully understand and predict future changes, therefore, high-resolution, welldated paleoclimate records are needed to...
