The bubonic plague or Black Death that scourged Europe in the 1340s seems to have been far more virulent and contagious than the Yersinia pestis microbe that survives today. Now an old plague-era London cemetery is yielding DNA evidence that may begin to answer some of the mysteries.

"BIBLIS, Germany — Not since the grim period after World War II has Germany had significant blackouts, but it is now bracing for that possibility after shutting down half its nuclear reactors practically overnight.

"One year after 1,900 people were sickened and a half-billion Iowa eggs were recalled, government inspectors continue to find unsanitary conditions and inadequate protections against salmonella on Iowa’s egg farms.

"Beyond flooding and destruction, Hurricane Irene is likely to have caused less visible environmental damage by dumping sewage, pesticides and other contaminants into waterways along the East Coast, federal officials said.

Today’s safety questions, though, aren’t nearly so black and white — and neither are the answers.

"The earthquake that rattled much of the East Coast last week is sparking angry calls from elected officials seeking an immediate reevaluation of seismic risks at two dozen or so commercial nuclear plants around the country, including two in California.

The frustration is directed at members of the federal agency charged with regulating commercial nuclear plants, the Nuclear Regulatory Commission."
