KOLKATA, India (Reuters) - Indian health authorities are using colorful aquarium fish with a taste for mosquito larve to fight a dengue epidemic that has left dozens dead, health officials said on Friday. Dengue, which is transmitted by mosquitoes, has killed about 50 people and affected hundreds in the past few weeks in the eastern state of West Bengal where authorities are struggling to control the disease. Health officials have released thousands of gambusia and guppies -- small,...

Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology. The researchers found that MXC, which was manufactured as a safer replacement for the now-banned DDT, alters the estrogen-regulated gene Hoxa10 in the reproductive tract and reduces the ability of the uterus to support embryo...

For those concerned with the troublesome effects of genetic resistance to drugs and pesticides, the conventional wisdom of evolution offers a reassuring word: In the absence of the original chemical threat, most resistance mutations would cause a disadvantage to their hosts and might be expected to quickly leave the genetic landscape once the use of a drug or insecticide is suspended or withdrawn. But emerging research suggests that such assumptions need reconsideration. Working with the...

By Michelle Rizzo NEW YORK (Reuters Health) - Results of a study hint that exposure to PCBs (polychlorinated biphenyls) increases the risk of the development of non-Hodgkin's lymphoma (NHL), a blood cancer involving the lymph nodes. The incidence of NHL has risen over the past several decades but the reasons for this are unclear, study investigators explain in the July issue of the journal Epidemiology. In a population-based, case-control study, they examined the association between NHL...

By Maggie Fox, Health and Science Correspondent WASHINGTON (Reuters) - Sea birds can spread pollutants such as mercury and pesticides across the Arctic in their droppings, Canadian researchers reported Thursday. The finding, published in the journal Science, surprised experts, who had presumed that the chemicals were being spread only by atmospheric winds. It could help explain the high levels of such pollutants found in the bodies of people living in and near the Arctic region, far from...

WASHINGTON -- Unborn U.S. babies are soaking in a stew of chemicals, including mercury, gasoline byproducts and pesticides, according to a report released on Thursday. Although the effects on the babies are not clear, the survey prompted several members of Congress to press for legislation that would strengthen controls on chemicals in the environment. The report by the Environmental Working Group is based on tests of 10 samples of umbilical-cord blood taken by the American Red Cross. They...

AVALON, Calif. (AP) -- Federal and state officials will stop funding a program to reintroduce bald eagles on Santa Catalina Island, but they could restart the project after 2007. Officials representing six environmental agencies made the decision as they determined how to spend $25 million in settlement money over the next five years. A Montrose Chemical Corp. factory near Torrance from 1947 to 1971 flushed the pesticide DDT into Los Angeles County sewers that empty into the ocean off the...

LOS ANGELES -- An important program that restored bald eagles to Santa Catalina Island after they were wiped out there 40 years ago is in danger of losing its funding to breeding sites on an island farther north. For nearly two decades, biologists have worked to get the adult eagles on Santa Catalina to reproduce without human assistance after contamination from chemical dumping caused their eggs to weaken and dehydrate. Now, a council that funds the project with money from an...
