A broad storm system spread heavy snow across the Great Lakes region Tuesday and fired up violent thunderstorms that knocked out power to thousands of homes and businesses in the Southeast.
When marauding Vikings decided to settle down they usually "went native,'' marrying local girls and blending in. Invading honey bees may be doing the same. The invasion of new bee populations has attracted attention in recent years with the spread of so-called Africanized, or "killer bees'' moving north from South America.
When a new strain of bees invades a region already populated by honey bees, they interbreed and gain benefits from the genes of their predecessors, researchers report in this week's edition of Proceedings of the National Academy of Sciences.

One man has died and another is missing after Japan was battered by strong winds on Sunday, officials said.
A 72-year-old fisherman died after being thrown out of his boat in high waves in the Sea of Japan off Toyama prefecture, northwest of Tokyo, a local government official said.
"Another man has separately been missing, while six others were injured in wind-related incidents," the official said, adding that more than 200 houses were flooded as high surf engulfed large areas near the coast.

A pygmy sperm whale found stranded off the Florida Keys was in critical condition at a rehabilitation center on Sunday.
The 10 1/2-foot long male was discovered Saturday off Islamorada and transferred to the Marine Mammal Conservancy in Key Largo.

An earthquake with a magnitude of 6.5 on the Richter scale hit Indonesia's Sumatra Island Sunday, but no injuries or tsunami warnings were reported initially.
An India-based meteorology agency measured the quake at 6.5, while the U.S. Geological Survey had it at 6.4. The temblor was felt throughout the island's Bengkulu province and in the province of West Sumatra, the state-run Chinese news agency Xinhua reported.

Protected forest strips buffering rivers and streams of the Amazon rainforest should be significantly wider than the current legal requirement, according to pioneering new research by scientists at the University of East Anglia. This is the first wildlife study on remnant riparian tropical forest corridors.
Brazilian forestry legislation currently requires that all forest strips alongside rivers and streams on private land be maintained as permanent reserves and it sets a minimum legal width of 60m.
But after investigating the effects of corridor width on the number of bird and mammal species, Alexander Lees and Dr Carlos Peres of UEA's School of Environmental Sciences say a minimum critical width of 400m is necessary.

They may be considered pests, but beaver can help mitigate the effects of drought, and because of that, their removal from wetlands to accommodate industrial, urban and agricultural demands should be avoided, according to a new University of Alberta study.
