LAS VEGAS, July 19, 2011 /PRNewswire/ -- The Environmental Protection Agency (EPA) "cherry-picked" research to support its biased air emission rules for power plants. The agency also avoided balanced peer review to build its case for stringent new controls on mercury emissions, an important new scientific review has concluded. Not only does EPA base its concerns about health risks on whale blubber, it ignores the skyrocketing, job-killing energy costs that employers and families will...

Feathers collected from the rare Pacific black-footed albatross over the past 120 years have helped researchers from Harvard University track increases in the neurotoxin methylmercury in the endangered bird, which forages extensively throughout the Pacific, reports AFP. Scientists took the feather samples from two US museum collections -- the Harvard University Museum of Comparative Zoology and the University of Washington Burke Museum of Natural History and Culture. Studies of the feathers...

A newly sequenced bacterial genome from a team led by the Department of Energy's Oak Ridge National Laboratory (ORNL) could contain clues as to how microorganisms produce a highly toxic form of mercury. Methylmercury, a potent human neurotoxin, appears in the environment when certain naturally occurring bacteria transform inorganic mercury into its more toxic cousin. Few bacterial species are capable of this conversion, and exactly how the transformation takes place has been a matter of...

Although research has shown that eating fish, which is rich in beneficial omega-3 fatty acids, is associated with lower risk of cardiovascular diseases, mixed evidence from prior studies has suggested that mercury exposure from fish consumption may be linked to higher risk of cardiovascular diseases. In a new, large-scale study from Harvard School of Public Health (HSPH) and Brigham and Women's Hospital (BWH), researchers found no evidence that higher levels of mercury exposure were...

Mercury contamination, a worldwide environmental problem, has been called "public enemy No. 1" in California's San Francisco Bay. Mercury mining and gold recovery in the mid-1800s to late 1900s, combined with present day oil refineries, chemical manufacturing plants and wastewater treatment plants have contributed enough mercury to threaten wildlife and prompt a fish consumption advisory in the Bay Area. With so many possible sources of contamination, environmental scientists and regulatory...

Nature has a bit of a Jekyll and Hyde relationship with mercury, but researchers at the Department of Energy's Oak Ridge National Laboratory have made a discovery that ultimately could help explain the split personality. While scientists have known that microbes in aquatic environments make methylmercury, a more toxic form of mercury that accumulates in fish, they also know that nature and other types of bacteria can transform methylmercury to less toxic forms. What they haven't completely...

WASHINGTON, Dec. 13, 2010 /PRNewswire-USNewswire/ -- While an FDA panel re-examines risks of amalgam over the next two days, the World Health Department is expected to release a key report soon recommending that amalgam use be "phased down" globally, consistent with its earlier recommendations.(i) "We welcome WHO's support for "phasing down" amalgam, and urge FDA to do the same," said Michael Bender, director of the Mercury Policy Project. On Dec. 14-15, 2010, an FDA panel will discuss...

YONKERS, N.Y., Dec. 7, 2010 /PRNewswire/ -- Consumer Reports' latest tests of 42 samples from cans and pouches of tuna bought primarily in the New York metropolitan area and online confirm that white (albacore) tuna usually contains far more mercury than light tuna. Canned tuna, Americans' favorite fish, is the most common source of mercury in our diet. The Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) say that women of childbearing age and young...

Fifty-seven laboratories from 29 countries volunteered to put their measuring competence to the test. Each laboratory received a sample without knowing the levels of heavy metals present, and was asked to measure and report the values back to the JRC. The good results should enhance consumers' confidence, as maximum levels of lead, cadmium and total mercury in seafood are regulated by EU law and it has been proven that most participants are able to correctly measure them. In addition, this...

Mercury (element) Mercury, also called quicksilver, is a chemical element in the periodic table that has the symbol Hg (from the Greek hydrargyrum, for watery (or liquid) silver) and atomic number 80. A heavy, silvery, transition metal, mercury is one of only two elements that are liquid at room temperature (the other is bromine). Mercury is used in thermometers, barometers and other scientific apparatuses. Mercury is mostly obtained by reduction from the mineral cinnabar. Notable...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
