The Economist is hosting a debate between Bruce Schneier and former TSA honcho Kip Hawley, on the proposition "This house believes that changes made to airport security since 9/11 have done more harm than good." I'm admittedly biased for Bruce's position (he's for the proposition), but it seems to me that no matter what your bias, Schneier totally crushed Hawley in the opening volley. The first commenter on the debate called Hawley's argument "post hoc reasoning at its most egregious," which sums it all up neatly.

While the brightest minds of Silicon Valley are "disrupting" whatever industry is too crippled to fend off their advances, something odd is happening to our language. Old, trusted words no longer mean what they used to mean; often, they don't mean anything at all. Our language, much like everything these days, has been hacked. Fuzzy, contentious, and complex ideas have been stripped of their subversive connotations and replaced by cleaner, shinier, and emptier alternatives; long-running debates about politics, rights, and freedoms have been recast in the seemingly natural language of economics, innovation, and efficiency. Complexity, as it turns out, is not particularly viral.

Millions of people log on to Lumosity daily to flex their brain muscles--and hopefully improve memory, attention and general cognitive performance in the process.  But this brain training site has recently garnered attention for a large-scale survey which found that better brain performance was linked to 7 hours of sleep per night,  aerobic activity 2-3 times per week and a daily cocktail.  While the overall efficacy of brain training remains hotly debated, Michael Scanlon, co-founder and Chief Scientific Officer of Lumos Labs (creator of Lumosity), discusses the findings from the study, what surprised him most and what we can take away from correlational data. 

A refrain running through the debate over global warming suggests we need to nothing to slow it, because after all, the climate science predicting more warming could turn out to be wrong. Giordano Bruno was burned at the stake, and Galileo almost was, for objecting to the scientific doctrine that the Sun revolves around the Earth. For two thousand years people believed in systems of physics and astronomy that turned out to be incorrect. And for a few more centuries after that they held to a new celestial mechanics only to see it displaced by relativity theory.

"Wikipedia founder Jimmy Wales has spoken out against the Draft Communications Bill, the UK government plans to monitor and store all digital communications, dubbed the "Snooper's Charter". In case Draft Communications Data Bill becomes the law, the US entrepreneur has promised to encrypt all connections between Wikipedia servers and the UK, effectively reducing the government's ability to snoop on use of Wikipedia. Wales was speaking to a  joint committee tasked with scrutinising the proposed Communications Bill before it is debated in the House of Commons."

A debate that has gone on for millennia has flared up again in recent years Is the fact you are reading this story a decision you arrived at it by your own free choice, or was your interest programmed into the universe from the moment of the big bang? What makes free will such a fun topic is not only that it dives deep into physics, neuroscience, and philosophy, but also that we all feel we have a direct stake in the answers.

UNU Media Centre head Brendan Barrett shares insights derived from a UNU Institute for Water, Environment and Health conference that focused on K* (K-Star) - a spectrum of ideas that covers research communication, science push, knowledge translation, adaptation, transfer and exchange, knowledge brokering and mobilization, and policy pull. * * * To sum up the underlying need for the recent K* Conference 2012, I borrow the words of a co-participant who explained that "as we are seeing with the climate debate and other 'wicked problems', it is not sufficient to assume that scientific consensus about the facts will be influential in policy or the wider community".
