Admit it. You've used the free, crowd-sourced entries of Wikipedia to brush up on history or look up a fact or two in many a trivia conundrum. And you're not alone. Since Wikipedia was launched more than a decade ago, millions of Web users have "Wikied" this or that.
But what have you done for Wikipedia lately?
Maybe you've added a sentence or two to an entry, or even created a new page about for your favorite up-and-coming indie artist.
The General Services Administration, which is tasked with developing the rules followed by other government agencies, is back in the limelight for the money it spent on a one-day event in the Washington, D.C. area.
In a letter to House members, the agency's inspector general says it has launched an investigation after its initial findings showed the GSA spent $268,732 on the event.
JACKIE NORTHAM, BYLINE: I'm Jackie Northam in Washington. Today at the U.N., Russia and China vetoed a Western-backed draft resolution that warned of sanctions against the Syrian regime unless it complies with a peace plan.
This is the third time those two countries have used their veto power to block a resolution on Syria. Britain's U.N. ambassador, Mark Lyall Grant, called the decision by Russia and China appalling, and said it would lead to further bloodshed in Syria.
Early in this show, fellow guest Tim O'Brien joked that the Ontario-based Great Lake Swimmers "had better get started" if they hoped to make it to the show on time. They didn't actually swim – but it was still great to have the Toronto band on an episode of Mountain Stage recorded on the shore of Lake Superior in Grand Marais, Minn.
Researchers studying brains want to know what's happening in an area called the premotor cortex — the place in the brain that gears up for something the body is about to do, like swimming. Above, Michael Phelps dives off the starting blocks in the final heat of the men's 400-meter individual medley during the 2012 U.S. Olympic Swimming Team Trials in Omaha, Neb., on June 25.
When Olympic swimmer Michael Phelps steps onto a starting block a few days from now, a Stanford scientist named Krishna Shenoy will be asking himself a question: "What's going on in Michael Phelps' brain?"
Specifically, Shenoy would like to know what's happening in an area called the premotor cortex. This area doesn't directly tell muscles what to do. But it's the place where the brain gears up for something the body is about to do, like swimming.
Longtime AIDS activist Dr. Ashraf Grimwood says South Africa has made huge strides in confronting HIV. But he worries that giving anti-retroviral drugs to healthy people could have negative consequences in the long term.
The news that the U.S. Food and Drug Administration this week approved the use of Truvada, an AIDS drug, to prevent infections in people who are HIV-negative is being greeted with skepticism, derision and even worry by some doctors in South Africa.
That's what one U.S. official says about the prospect that Syria's vast stockpile of chemical weapons might be used against rebel forces. From a U.S. national security standpoint, an even worse outcome would be for those weapons to fall into the hands of terrorists.
Here's your vocabulary word for the week: zoonosis. It describes an infection that is transmitted between species. For example, the disease that the husband and wife team of Bill Wasik and Monica Murphy have written about in their new book, Rabid: A Cultural History of the World's Most Diabolical Virus.
