Years ago the city of Grand Rapids, Michigan, changed its policy on dealing with the emerald ash borer (EAB), a pretty but deadly insect that has killed many of the state’s ash trees.
Instead of cutting down all ash trees, they allowed residents to treat high-value trees with insecticides at their own expense, says Kathy Quick, an assistant professor in the University of Minnesota’s Humphrey School of Public Affairs who was working in Grand Rapids at the time.(more…)
SACRAMENTO, Calif. — A study on frogs in remote Sierra Nevada mountain habitats including Yosemite National Park and Giant Sequoia National Monument, detected concentrations of pesticides in frog tissue that potentially came from California’s Central Valley sources.
“Our results show that current-use pesticides, particularly fungicides, are accumulating in the bodies of Pacific chorus frogs in the Sierra Nevada,” says Kelly Smalling, a research hydrologist with the U.S. Geological Survey and lead author of the study. “This is the first time we’ve detected many of these compounds, including fungicides, in the Sierra Nevada. The data generated by this study support past research on the potential of pesticides to be transported by wind or rain from the Central Valley to the Sierras.” (more…)
Studying bacteria from the Baltic Sea, UA researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses.
Researchers of the University of Arizona’s Tucson Marine Phage Lab have discovered a dozen new types of unknown viruses that infect different strains of marine bacteria. (more…)
Asian Indians are one of the fastest growing ethnic groups in the United States, and roughly half a million people of Indian ancestry live in California — more than any other state. Individuals from this group are strongly predisposed to obesity-related conditions such as diabetes and heart disease, due in large part to physical inactivity, diets low in fruit and vegetables, and insulin resistance.
Among other racial and ethnic groups, research has shown that religious practices and religiosity have been associated with obesity and greater body weight, but no one had studied this potential link among Indians. (more…)
A team of researchers at the IRCM, led by Dr. Javier M. Di Noia in the Immunity and Viral Infections research division, discovered a novel research model for the study of auto-immune diseases. The Montréal scientists are the first to find a way to separate two important mechanisms that improve the quality of antibodies. This study was featured in a recent issue of The Journal of Immunology.(more…)
New study shows healthy Red Sea corals carry bacterial communities within
Corals may let certain bacteria get under its skin, according to a new study by researchers at Woods Hole Oceanographic Institution (WHOI) and King Abdullah University of Science and Technology (KAUST) and soon to be published in the journal Applied and Environmental Microbiology. The study offers the first direct evidence that Stylophora pistillata, a species of reef-building coral found throughout the Indian and west Pacific Oceans, harbors bacterial denizens deep within its tissues.
“We have evidence that other species of coral also host these bacteria, and that they may play an important role in keeping a coral healthy,” says Amy Apprill, a WHOI assistant scientist who co-directed the study along with KAUST Assistant Professor Christian Voolstra. KAUST post-doctoral scholar Till Bayer was the lead author of the study. (more…)
Low vitamin D blood levels are linked to greater risk of heart disease in whites and Chinese, but not in blacks and Hispanics, according to a study appearing this week in JAMA, the Journal of the American Medical Association.
Growing evidence has suggested that low blood levels of 25-hydroxyvitamin are associated with higher risk of developing coronary heart disease among whites. Few of these studies included substantial numbers of people from other races. (more…)
