CAMBRIDGE, Mass. —Economist Paul A. Samuelson, a Nobel laureate and winner of the National Medal of Science, has died. He was 94.
The Massachusetts Institute of Technology, where Samuelson taught, says he died Sunday at his home in Belmont, Mass.
Samuelson was one of the leading economists of the 20th century and served as an adviser to Presidents John F. Kennedy and Lyndon B. Johnson. He won the Nobel Prize in 1970.
Search continues for missing Utah woman
SALT LAKE CITY — Police had little to go on Sunday in the search for a Utah woman who hasn't been seen for a week.
Twenty-eight-year-old Susan Powell was reported missing from a Salt Lake City suburb in a case that police call suspicious.
She left behind two children and a husband, who says he doesn't know what happened to her.
West Valley City police Capt. Tom McLachlan says at least eight detectives worked the case Sunday, fielding any tips or leads they can get from the family or friends.
Helicopter searches for climbers in Oregon
GOVERNMENT CAMP, Ore. —Fears of an avalanche on Mount Hood forced rescuers to use a helicopter and airplanes in their search for two missing climbers on Sunday, a day after crews found the body of their climbing companion on a glacier on Oregon's highest mountain.
Eight inches of snow fell on the 11,249-foot mountain overnight, and avalanche dangers in the higher elevations made a rescue mission on foot too risky.
