Astronomers have identified a star system just 22 light years from Earth with three planets that could potentially harbor life. The Gliese star system is easy to locate in the constellation Scorpius. The two main stars, Gliese 667A and B, are visible to the naked eye, but the one with the planets, Gliese 667C, requires a telescope to see. Gliese 667C has 7 planets, and 3 of them are in its habitable zone, which is the region around the star where temperatures would not be too high or too low for life to form, and where water would be a liquid. Earth is near the center of the sun’s habitable zone, and Venus and Mars are at its extremes.

Scientists have discovered that one of the primary things that has made us human is a surprising one: our ability to throw.

Researcher Neil T. Roach proposes that this ability first evolved nearly 2 million years ago to aid in hunting. Humans are unique in their throwing ability, even when compared to our chimpanzee cousins.

He says, "Chimpanzees are incredibly strong and athletic, yet adult male chimps can only throw about 20 miles per hour–one-third the speed of a 12-year-old little league pitcher." (Throwing sports, like baseball, are literally in our genes.)

In November of 2010, the existence of the Stuxnet virus was disclosed to reporters. The virus had been used by the US in a hacking attack to cause centrifuges in Iranian uranium enrichment facilities to fail, setting their nuclear weapons program back years. It turns out that this particular leak wasn’t carried out by a low-level individual, but allegedly by a member of the Joint Chiefs of Staff. The U.S. Department of Justice has told retired Marine General James Cartwright, who was vice chairman of the Joint Chiefs of Staff from 2007 to 2011, that he is a target in the investigation. He faces allegations that he provided reporters with information about Stuxnet.
