Irish Moss, Chondrus crispus
Andrea Ottesen, University of Maryland
"The slimy, glistening mass of seaweed washed up on a sandy beach seems light-years distant from this feathery, dendritic image of Irish moss (Chondrus crispus) created by Andrea Ottesen, a botanist and molecular ecologist at the University of Maryland, College Park. "If you pull Chondrus out of the ocean, it's folded on itself—really curled up," she says. It wasn't until after she had "pressed every one of those little ends down with sea stones" and left it to dry for 2 days that the seaweed's beautiful, simple shape was revealed. Besides being one of the most common seaweed species on the Atlantic coast, says Ottesen, Irish moss and algae like it are sources of natural thickeners and stabilizers called carrageenans, which are widely used in processed foods as diverse as lunch meat and ice cream." -- Winner 2007 NSA Scientific Image ContestPosted by Vanderleun at March 24, 2008 10:34 AM | TrackBack
