Taking birth control pills may increase a woman's risk of eye disease later in life, a study finds, because they may reduce protective levels of estrogen.
Doctors have long known that cells in the eye have estrogen receptors. But in the past few years they've started looking into whether the changes in a woman's estrogen levels as she goes through life could affect her risk of glaucoma.
As the United States becomes a net exporter of oil for the first time since 1995, the Eagle Ford Shale deposit hums away with activity. The environmental costs have been becoming better documented and one correlation becomes stronger and stronger -- the link between certain hydraulic fracturing disposal methods and earthquakes.
In his new book My Promised Land: The Triumph and Tragedy of Israel, Israeli journalist Ari Shavit tackles several basic questions: Why was Israel created? What has it achieved? What went wrong? Where is it heading? Will it survive?
The book is based on interviews with hundreds of Israelis — Jews and Arabs — as well as his own story and family history (two of Shavit's great-grandfathers became Zionists in the late 1800s).

"It is fitting that San Antonio should be the site of this center and this school [Brooks Air Force Base School of Aerospace Medicine and the Aerospace Medical Center]."

NASA's MAVEN explorer blasted off Monday on the first leg of its 440-million-mile journey to Mars, where scientists hope it will answer an ancient question: why the red planet went from warm and wet to cold and dry in a matter of just a billion years.
The robot orbiter, called the Mars Atmosphere and Volatile Evolution probe, launched aboard an Atlas V rocket from Cape Canaveral Air Force Station at 1:28 p.m. EST. It will take 10 months to reach Mars.

Workers at Japan's Fukushima Dai-Ichi nuclear power station successfully completed the first day of a delicate operation to remove radioactive fuel rods from a reactor damaged in the March 2011 tsunami.
The fuel rods were removed from the Unit 4 reactor, which was offline at the time the tsunami smashed into the plant, overwhelming its backup systems. Although Unit 4 was spared the fate of three other reactors that melted down, a fire in its containment building weakened the structure.
On Wednesday, November 18, 1863 a special train left Washington, D.C. for Gettysburg, Pennsylvania. Depressed due to the Union military situation at both Chattanooga and Knoxville and because of Tad Lincoln’s illness, President Abraham Lincoln related few stories en route.
To his secretary John Hay, Lincoln remarked that he felt weak. Upon arriving at Gettysburg, the president spoke briefly to a small crowd outside the Wills House, where he was staying the night, and then retired to work on his remarks for the following day.
