In1948, Mildred Gillars, accused of being Naziwartime radio propagandist "Axis Sally," pleaded not guilty in Washington, D.C., to charges of treason. (Gillars, later convicted, ended upserving 12 years in prison.) In1955, President Dwight D. Eisenhower suffered a heart attack while on vacation in Denver. In1960, the USSEnterprise, the first nuclear-powered aircraft carrier, was launchedat Newport News, Virginia. In1976,former hostage Patricia Hearst was sentencedto seven years in prison for her part in a1974 bank robbery in San Francisco carried out by the Symbionese Liberation Army.

The heads of theGroup of 20 nations began a two-day meeting in Pittsburgh aimedat making sure afledgling global recovery remained ontrack. One year ago:President Barack Obama andnew Iranian President HasanRouhani appeared separately before the U.N. General Assembly, with both leaders speaking up for improved relations and a resumption of stalled nuclear talks but giving no ground on long-held positions that had scuttled previous attempts to break the impasse.

BIRTHDAYS

Polar bears have become a symbol of the danger of global warming, but in Canada's Hudson Bay, scientists have found that our understanding of climate change may not be as simple as it seemed. Case in point: Polar bears have gotten lucky in one area, in that they have something new to eat.

"Because our economy is so bad," he said, "we need to focus on it and on jobs and not worry so much about global warming." Fifty-four percent said the warming was caused by human behavior.
