Weighing 400 grams, the Olympic gold medals that are being doled out at the London 2012 Summer Games are the heaviest ever, according to reports. But that doesn't mean they're the most valuable: at an estimated $620.82, they're nearly $590 short of the $1,207.86 value held by a gold medal from the Stockholm Games of 1912.
The discrepancy stems from the fact that the 2012 gold medals contain only 6 grams of gold; the rest is silver and copper. In fact, the London bling contains more copper than gold, which is only used to coat the medals with a plating layer.
Scientists reported new evidence Wednesday that supports a provocative theory about cancer.
Three separate teams of scientists said they had, for the first time, shown that so-called cancer stem cells can be found naturally in brain tumors and early forms of skin and colon cancer.
Evidence has been mounting in recent years for the existence of these cells, which would be especially insidious. They are believed to resist standard chemotherapy and radiation and fuel the growth of tumors and relapses.
As the presumptive presidential nominee, former Massachusetts Gov. Mitt Romney is currently the face of the Republican Party.

Canadian rower Michael Braithwaite is pumped and probably a little nervous. It's the day before the double sculls (two person team) competition at the London Olympics and the British Columbia native is hoping his strong arms and shoulders will bring him gold.
I'm Michel Martin and this is TELL ME MORE from NPR News. Later in the program, we'll hear about some important provisions in the health care overhaul bill that go into effect today. Now, a number of these provisions remain controversial but we're going to step aside from the politics for a minute to try to find out what they mean for individuals. That's coming up later in the program.
The Olympics are a quest to be the best. But some Olympians are accused of purposely playing badly at badminton. The Badminton World Federation has launched disciplinary proceedings against four women's doubles pairs. First, the world champions, who are Chinese, faced off against opponents from South Korea. And spectators started booing when the players seemed to be making simple errors on purpose.
