"Drones' greatest attraction for the national security world is that they create options where there were none - or none at a cost policymakers feel comfortable with. With a public tired of large scale military interventions, drones and other approaches that gave the U.S. options to study or intervene against security challenges in a low profile, low risk way fit perfectly into the Obama administration's comfort zone. These platforms came to symbolize and enable much of the Obama national security team's approach. But the enthusiastic embrace of drone technology, particularly in counterterrorism, left some former Obama officials questioning whether they'd been clutching a Pandora's box they should have opened more deliberately. Overall, such "light footprint" strategies generate enduring disagreements about their efficacy, risk, and oversight. Unlike any other recent military platform, drones in particular engender strong emotion - hope, revulsion, overconfidence, demonization - and magical thinking, even among those who know them best. And the attributes that make them so compelling - that they are precise, remote, sensing, and unmanned - may sometimes be too reassuring."

"his paper takes stock of megaproject management, an emerging and hugely costly field of study. First, it answers the question of how large megaprojects are by measuring them in the units mega, giga, and tera, concluding we are presently entering a new "tera era" of trillion-dollar projects. Second, total global megaproject spending is assessed, at USD 6-9 trillion annually, or 8 percent of total global GDP, which denotes the biggest investment boom in human history. Third, four "sublimes" - political, technological, economic, and aesthetic - are identified to explain the increased size and frequency of megaprojects. Fourth, the "iron law of megaprojects" is laid out and documented: Over budget, over time, over and over again. Moreover, the "break-fix model" of megaproject management is introduced as an explanation of the iron law. Fifth, Albert O. Hirschman's theory of the Hiding Hand is revisited and critiqued as unfounded and corrupting for megaproject thinking in both the academy and policy. Sixth, it is shown how megaprojects are systematically subject to "survival of the unfittest," explaining why the worst projects get built instead of the best. Finally, it is argued that the conventional way of managing megaprojects has reached a "tension point," where tradition is challenged and reform is emerging. "

"When animals die, waves of microbes consume their corpses. Scientists have looked at how this "necrobiome" changes over the hours and days after an animal perishes. But Saitta's work suggests that microbes continue to colonize cadavers long after their flesh has decayed, after their bones have turned to stone, and after they've been buried several miles deep for millions of years.   MORE STORIES A Dinosaur So Well Preserved, It Looks Like a Statue ED YONG How a Fossil Can Reveal the Color of a Dinosaur CARI ROMM The Counterintuitive Way That Microbes Survive in Antarctica ED YONG The Scientist Who Stumbled Upon a Tick Full of 20-Million-Year-Old Blood SARAH ZHANG That came as a huge surprise to Tullis Onstott, a microbiologist from Princeton who worked with Saitta, and who always thought of fossils as inert and inanimate. "I thought that dinosaur bone must be some kind of sealed sarcophagus," he says. "It's not, by any means. It's basically a condo for bacteria. Now the question becomes: Is this true for all dinosaur bones?""

"We use the word "authority" to mean lots of things - police and state actors are "the authorities", an expert may be "an authority on the matter, etc. But I want to suggest that it is very useful to think of authority as a characteristic of information in a social context. In particular, information is "authoritative" when some community of people to coordinate upon it and behave as if it were true, regardless of whether or not the information is in fact true, or even of whether the individuals doing the behaving personally believe it to be true. If information is authoritative, members of the community behave as if the information is true even despite strong, often opposing interests in the question. When we claim that someone "is an authority", we are claiming that the information they produce will (or should) alter behavior within some human community. Authority subsists in the relationship between information and behavior in a social context."
