Uncommon helmet headed to auction
A helmet that is considered an extraordinary example of Roman metalwork is scheduled to be auctioned next month by Christie's in London. The helmet, which dates from the late first century, was discovered in a field in northwestern England by a treasure-hunter with a metal detector. Christie's said Monday that the helmet could fetch $242,000 to $363,000 when auctioned Oct. 7.
Melting ice sends walruses ashore
Tens of thousands of walruses have come ashore in northwest Alaska because the sea ice they normally rest on has melted. Federal scientists say this massive move to shore by walruses is unusual in the United States. But it has happened at least twice before, in 2007 and 2009. In those years arctic sea ice also was at or near record low levels. U.S. Geological Survey biologist Anthony Fischbach said scientists don't know how long the walrus camp-out near Point Lay, Alaska, on the Chukchi Sea will last, but there should be enough food for all of them.
Drug-resistant superbug enters U.S.

An infectious-disease nightmare is unfolding: Bacteria that have been made resistant to nearly all antibiotics by an alarming new gene have sickened people in California, Massachusetts and Illinois and are popping up all over the world, health officials reported Monday at an American Society for Microbiology conference in Boston.
The U.S. cases and two in Canada all involve people who had recently received medical care in India, where the problem is widespread.
A British medical journal revealed the risk last month in an article describing dozens of cases in Britain in people who had gone to India for medical procedures.
How many deaths the gene may have caused is unknown; there is no central tracking of such cases. So far, the gene has mostly been found in bacteria that cause gut or urinary infections.
Scientists have long feared this — a very adaptable gene that hitches onto many types of common germs and confers broad drug resistance, creating dangerous "superbugs."
"It's a great concern," because drug resistance has been rising and few new antibiotics are in development, said Dr. M. Lindsay Grayson, director of infectious diseases at the University of Melbourne in Australia. "It's just a matter of time" until the gene spreads more widely person to person, he said.
