World affairs have been a constant presence in Mika Brzezinski's life since she was a young girl. Her father, Zbigniew Brzezinski, was the powerful National Security Adviser to President Jimmy Carter. She spent her young adulthood behind or in front of TV cameras, working her way up as a broadcaster on ABC, Fox and CBS, where she worked as an anchor and 60 Minutes correspondent. In 2006, however, she was unceremoniously (and very publicly) let go for reasons she says she still doesn't understand. Brzezinski is currently the co-host of the MSNBC show Morning Joe, with...
...beginning. Until that happens, however, both sides will remain locked in a nightmarish anachronism, with nuclear annihilation of both sides always only minutes away. As Andreasen says, "Most experts agree: We will need to do more than the new START, with greater urgency and on a much broader front, to get ahead of the nuclear danger...
...blow up a flight to Detroit on Christmas Day, trained for his mission with al-Qaeda operatives in Yemen has renewed attention on the nation as a breeding ground for extremists. Saleh - a professed U.S. Ally - has promised action and indeed has sent hundreds of extra soldiers to the front lines of al-Qaeda-dominated territory east of Sana'a. But U.S. officials view him as a fickle leader facing a difficult array of threats - from a sectarian rebellion in the north and a secessionist movement in the south, to say nothing of dwindling water supplies and oil reserves...
Still, even these planetary finds are unlikely to be exact copies of Earth, and for a very simple reason. Kepler spots faraway planets by watching them transit, or pass in front of, their stars, blocking out a little bit of light and making the star slightly dimmer. The five planets just announced orbit very close to their suns, which is the reason they're so ridiculously hot. That proximity also means they move very fast, completing three or even more transits in the first round of observations - which is just the kind of data stream the Kepler team prefers...
Still, Kepler has had some tantalizing news on the biology front too. While looking for planets, the probe has been taking note of the behavior of the stars themselves. Our sun is remarkably steady, without dramatic changes in warmth and brightness that might have prevented the emergence and evolution of life - and Kepler now reports that two-thirds of the sunlike stars it's monitoring are no more active than the sun at its most turbulent. Lots of stable suns could mean at least a handful of promising Earths - and those, in turn, could mean living company...
