"Scientists have mapped out the entire genetic map of the Black Death, a 14th century bubonic plague that killed 50 million Europeans in one of the most devastating epidemics in history.

The work, which involved extracting and purifying DNA from the remains of Black death victims buried in London's "plague pits," is the first time scientists have been able to draft a reconstructed genome of any ancient pathogen.

The Obama White House issued a strong statement Wednesday opposing a bill by Rep. David McKinley (R-WV) that would prevent the Environmental Protection Agency from regulating the disposal of coal ash. A 2008 failure of a TVA coal-ash in Kingston, Tennessee, caused major property and environmental damage.

EPA's official investigation of a massive 2009 fish kill in West Virginia's Dunkard Creek ended by blaming the pollution squarely on Consol Energy's Blacksville No. 2 mine. But an EPA biologist said that coal mine drainage alone was not enough to explain the problem -- and that contamination of mine pools by methane and water from the Marcellus Shale formation was possibly an additional cause.

"UNITED NATIONS -- Conservationists and the international fishing industry are gearing up for another showdown over the fishing method known as bottom trawling next month, when U.N. officials return to what has probably been the most intensely debated fisheries issue to feature here over the last decade."

"America must stop promoting the production of biofuels if there is to be any real progress in addressing spiking global food prices and famine, such as seen in the Horn of Africa, an authoritative thinktank has warned."

"NEW ORLEANS -- Federal regulators on Wednesday cited oil company BP PLC and two other companies – Transocean Ltd. and Halliburton – for alleged safety and environmental violations stemming from last year's rig explosion and massive Gulf oil spill.

The companies have 60 days to appeal the citations issued by the Interior Department's Bureau of Safety and Environmental Enforcement.

The bureau says the alleged regulatory violations could result in civil penalties once the appeal period has ended.

"The conservative nonprofit Americans for Prosperity unleashed a volley of ads aimed at Democrats in last year's midterm elections, but it recently reported to the IRS that it was not active in political campaign activities."
