WASHINGTON -- Researchers told lawmakers Tuesday that they may have two new weapons against the quagga mussel, an invasive mollusk that clogs municipal water pipes, takes food from native species and may even stimulate the deadly bacteria that cause botulism. The thumbnail-sized mussel has a high reproduction rate and no natural predators, and it's a big and growing worry in the Great Lakes, the Colorado River, Lake Havasu and Lake Mead. More recently, quagga mussels have turned up in...

By Steven Kalas He's not in love anymore. When he says it, I think of Dorothy holding her scruffy dog and saying, "I don't think we're in Kansas anymore, Toto." He's dismayed. A little awed. Eyes wide. Unsure. But relieved. Ever so relieved. And maybe a little anxious, too, like, if he surrenders to the relief and enjoys it, then perhaps he'll relapse into heartsickness once again. I'm not Jewish, but still I pantomime raising a glass of wine and I say, "Mazel tov!" Almost three years...

Central California lakes and waterways are being threatened by tiny mollusk invaders that pose as hitchhikers. Because quagga and zebra mussels are spread primarily through human-related activities, the Department of Fish and Game is asking for cooperation from boaters to prevent these destructive species from gaining a foothold in the San Joaquin Valley. Many other areas of the state have been on high alert since last fall, when quagga mussels were discovered in numerous places along the...

LAKE WORTH, Fla. - A Florida man was about halfway through a plate of steamed clams when he chomped down on something hard - a rare, iridescent purple pearl. George Brock and his wife, Leslie, had been spending a day at the beach Friday in South Florida and stopped at Dave's Last Resort & Raw Bar for a bite. Their find could be worth thousands. "Few are round and few are a lovely color, so this is rare," said gemologist Antoinette Matlins. "I think they have found something precious and...

By Erin Fuchs, Chattanooga Times/Free Press, Tenn. Oct. 28--DALTON, Ga. -- During a summer survey of freshwater mussels, conservationist Nate Thomas saw the mollusks struggling to find enough water in the Conasauga River to thrive. "You could literally see the trails the shells made (in the mud) as they moved up and down the bank, looking for water," said Mr. Thomas, who runs The Nature Conservancy's North Georgia operation. "Some of them made it. Some of them didn't." The Conasauga...

By SETH BORENSTEIN By Seth Borenstein The Associated Press In one of the earliest hints of "modern" living, humans 164,000 years ago put on primitive makeup and hit the seashore for steaming mussels, new archaeological finds show. Call it a beach party for early man. But it's a beach party thrown by people who weren't supposed to be advanced enough for this type of behavior. What was found in a cave in South Africa may change how scientists believe Homo sapiens marched into...
