President Obama began last year's State of the Union address by recognizing recently returned Iraq War veterans, adding: "At the end of World War II, when another generation of heroes returned home from combat, they built the strongest economy and middle class the world has ever known." Expect more historical references in Obama's Tuesday night address to a joint session of Congress.
Sometimes the best way to advance an argument is by looking back.
President Obama's second inaugural address was filled with historical allusions. His State of the Union address on Tuesday, which will lay out a long list of agenda items for the year and his second term, is likely to employ fewer references to the past.
A common vitamin supplement appears to dramatically reduce a woman's risk of having a child with autism.
A study of more than 85,000 women in Norway found that those who started taking folic acid before getting pregnant were about 40 percent less likely to have a child who developed the disorder, researchers reported in the Journal of the American Medical Association.
North Korea's latest nuclear weapons test is much more powerful than the previous two, according to estimates made by instruments that measure seismic waves from the blast. It's about the size of the bomb that devastated Hiroshima in World War II.
But it's not so easy to verify the claim that the nuclear explosive has also been miniaturized. That's a critical claim because a small warhead would be essential if the rogue regime chose to threaten the United States with a nuclear-tipped missile.
Big bombs are easier to make, but they aren't all that useful as a threat.
The late civil rights icon Rosa Parks, who broke racial barriers in 1955 when she would not move to the back of a segregated bus in Montgomery, Ala., will be posthumously part of another barrier-breaking moment on Feb. 27.
The office of House Speaker John Boehner, R-Ohio, announced Tuesday that a statue of Parks will be dedicated that day in the National Statuary Hall of the U.S. Capitol.
