"New research suggests that space rocks as large as the one that fell over Chelyabinsk -- about 19 meters (62 feet) across -- are three to five times more numerous than scientists had realized. The study, led by Peter Brown at the University of Western Ontario, also found that larger and more dangerous ones are unexpectedly abundant. In other words, alien projectiles pose a serious threat. Is it a manageable one?"
In the debut issue of PoliticoMagazine, Micah Zenko discusses the current drone market and implications of inevitable proliferation of armed drones. Citing the White House's lack of reform and transparency, Micah writes, "When Chinese officials authorize their first drone strike against a drug kingpin in Myanmar or against Japanese citizens occupying a disputed East China Sea island, what will the White House say then?"
"On November 11, it is worth remembering that the investments involved in preserving peace in Europe are peanuts compared to the price of war. In terms of value for money, the EU is a bargain. So too is NATO. Even the largely dysfunctional UN is, on balance, a cheap asset. Today's anniversary can still offer quite a few political lessons. Unfortunately, they are all about hard work."
"One problem with economics is that it is necessarily focused on policy, rather than discovery of fundamentals. Nobody really cares much about economic data except as a guide to policy: economic phenomena do not have the same intrinsic fascination for us as the internal resonances of the atom or the functioning of the vesicles and other organelles of a living cell. We judge economics by what it can produce. As such, economics is rather more like engineering than physics, more practical than spiritual."
Julia Sweig reflects on Washington's inconsistent response to outrage from foreign leaders at revelations of NSA spying, and on the roots and the implications of the United States' Euro-centric diplomacy.
The NSA revelations have already resulted in policy changes, but this will not be Edward Snowden's most meaningful impact. Rather, "The default appeal to 9/11 and vague warnings of terrorism that Bush and Obama administration officials relied upon to shape opinions and silence critics is no longer sufficient or acceptable," writes Micah Zenko.
