In astronomical terms, a blue moon really doesn't denote that long a time span. In fact, a blue moon happens once every 2.7 years on average.

Still, it's a special event that, at least using its modern definition, happens when there are two full moons in a single month.

Today (Aug. 1) we'll see a full-moon and that is a prelude to the blue moon of Aug. 31. As Space.com reports, the Aug. 31 moon will reach its full phase during the day.

What's A Gold Medal Really Worth?

Plenty To Smile About: Weightlifter Maiya Maneza of Kazakhstan celebrates on the podium with her new 400-gram gold medal, matching the feat of her compatriot Zulfiya Chinshanlo. The Kazakh Olympians will each receive a $250,000 bonus.

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.
