The emerging threat of pesticide resistance means that biological malaria control methods are once again in vogue. view more (2007-08-09)
Snails and humans use same genes to tell right from left
Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body. view more (2008-12-22)
Parasitic worms make sex worthwhile
The coevolutionary struggle between a New Zealand snail and its worm parasite makes sex advantageous for the snail, whose females favor asexual reproduction in the absence of parasites, say Indiana University Bloomington and Swiss Federal Institute of Technology biologists in this week's Current Biology. view more (2009-07-24)
Alcohol activates cellular changes that make tumor cells spread
Alcohol consumption has long been linked to cancer and its spread, but the underlying mechanism has never been clear. view more (2009-10-27)
How healthy is that marsh? Biologists count parasites
Is that salt marsh healthy? To answer this, Sea Grant biologists are cracking open common marsh snails and counting parasitic worms. Their claim: the more parasites, the healthier the marsh. view more (2006-05-19)
Biosensors to probe the metals menace
Researchers from CRC CARE are pioneering a world-first technology to warn people if their local water or air is contaminated with dangerous levels of toxic heavy metals and metal-like substances. view more (2007-08-30)
Study finds role for parasites in evolution of sex
What's so great about sex? From an evolutionary perspective, the answer is not as obvious as one might think. view more (2009-07-07)
Controlling schistosomiasis: buffalo or snails?
A parasitic infection common in China and Southeast Asia could be effectively reduced by controlling snail populations, according to research published in PLoS Medicine. view more (2008-01-22)
A new tool against brain disease
University of Utah researchers isolated an unusual nerve toxin in an ocean-dwelling snail, and say its ability to glom onto the brain's nicotine receptors may be useful for designing new drugs to treat a variety of psychiatric and brain diseases. view more (2006-08-21)
Ecological communities suffer dramatic changes when non-native species are introduced by humans!
Ecological communities suffer dramatic changes when non-native species are introduced by humans. Such introductions have been documented in hundreds of locations and appear to be common in marine and island habitats. One of the best-studied cases of a species that suddenly appeared in the New England intertidal, and subsequently spread rapidly... view more... (2002-07-11)
New Medicines At Risk From Biodiversity Loss
Science study reveals that habitat loss and overexploitation imperil the world's most promising source of new drugs In a letter published in the October 17th issue of Science, three scientists warn that biodiversity loss could have devastating consequences for drug discovery and the development of new medicines. "Tropical cone snails may... view more... (2003-10-22)
Penn Biologists Demonstrate that Size Matters-in Snail Shells
A team of biologists at the University of Pennsylvania has completed a research study begun in 1915 and determined that a snail making its home in the northwest Atlantic Ocean around Mount Desert Island, Me., has experienced a dramatic increase in the size of its shell during less than a century, providing a clear illustration of how fast and... view more...

Surprising Killer of Southeastern Salt Marshes: Common Sea Snails
Periwinkles, the spiral-shelled snails commonly found along rocky U.S. shorelines, play a primary role in the unprecedented disappearance of salt marsh in the southeastern states, according to new research published in Science. view more (2005-12-16)
MSU researcher finds renewed interest in turning algae into fuel
The same brown algae that cover rocks and cause anglers to slip while fly fishing contain oil that can be turned into diesel fuel, says a Montana State University microbiologist. view more (2008-01-16)
Winner of 2004 EMBO Science Writing Prize Announced
The winner of the 2004 EMBO Science Writing Prize is Matthew Bottomley of the Istituto di Ricerche di Biologia Molecolare in Rome, Italy. The winning piece, entitled "From Hawaii with Love", takes a novel and entertaining look at the use of quorum-sensing systems in transcriptional regulation of bacteria. view more (2004-08-30)
Invasive species threaten critical habitats, oyster among victims
A study of oyster reefs in a once-pristine California coastal estuary found them devastated by invasive Atlantic Coast crabs and snails, providing new evidence of the consequences when human activities move species beyond their natural borders. view more (2009-07-20)
Alberta's hidden valleys offer both resources and danger
Alberta is crisscrossed with hidden glacial valleys that hold both resource treasures and potential danger. University of Alberta researcher Doug Schmitt discovered a 300 metre deep, valley hidden beneath the surface of the ground near the community of Rainbow Lake in northwestern Alberta. view more (2009-11-13)
New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Polarized light guides cholera-carrying midges that contaminate water supplies
Cholera is a major killer and since the first pandemic in the early 19th century it has claimed millions of lives. According to Amit Lerner from The Hebrew University of Jerusalem, Israel, the lethal infection is harboured by an equally infamous insect: chironomids (midges). view more (2008-10-31)
Study shows that parasites form the thread of food webs
Scientists have discovered that parasites are suprisingly important in food webs and their findings appear in a report published this week in the Early Edition of the on-line version of the Proceedings of the National Academy of Sciences. view more (2006-07-13)
