Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

By Marcia Wood, ARS Eating raw or undercooked mollusks may pose a safety hazard if they are harvested from waters polluted with pathogenic microbes, so U.S. Department of Agriculture (USDA) scientists are studying ways to enhance the food safety of these popular shellfish. For example, USDA molecular biologist David H. Kingsley at Delaware State University in Dover is exploring new techniques that will decontaminate mollusks while protecting the seafood's flavor, texture, and color. Kingsley,...

Discovery lays groundwork for better understanding of protective human microbes in the gut Medical researchers have long suspected that obscure bacteria living within the intestinal tract may help keep the human immune system in balance. An international collaboration co-led by scientists at NYU Langone Medical Center has now identified a bizarre-looking microbial species that can single-handedly spur the production of specialized immune cells in mice. This remarkable activation of the immune...

 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.The scientists' report represents direct experimental evidence for the "Red Queen Hypothesis" of sex, which suggests sexual reproduction allows host species to avoid infection by their...

WASHINGTON -- The growing number of deformed frogs in recent years is caused at least partly by runoff from farming and ranching, new research indicates. Nitrogen and phosphorous in the runoff fuel a cycle that results in a parasitic infection of tadpoles, resulting in loss of legs, extra legs or other deformities, according to researchers led by Pieter Johnson of the University of Colorado, Boulder. Their findings are being published in this week's online edition of Proceedings of the...

New regulations that took effect on Saturday prohibit labs from experimenting on risky pathogenic microbes without approval. The Chinese cabinet issued the new rules after an incident in March in which two people were infected by the SARS (severe acute respiratory syndrome) virus at a lab of the Chinese Centre for Disease Control and Prevention. China will grade its pathogenic microbe labs in four levels. The first and second grades are labs prohibited from conducting experiments on risky...

Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
