In Narang’s office, the shades are drawn, the better to read a large monitor on one wall. There are no tickers scrolling by, no flashing updates on the value of the Dow Jones index. Narang’s strategy is “market neutral,” meaning that when it works–and it usually does–he makes money no matter which way the market goes. His profits don’t depend on whether share prices rise or fall; instead, he relies on a set of algorithms that can find and instantly take advantage of tiny, fleeting movements in trading activity. On the wall across from the window is a whiteboard filled with code: a scribbled flowchart in different colors, with variables and occasional amounts in boxes and the words buy or sell. In the middle of the monitor is a large number in a box, going up and down but mainly up. That is Tradeworx’s profit so far that morning.–“Trading Shares in Milliseconds,” Technology Review, by Harper’s contributor Bryant Urstadt

Centropomis undecimalis. Common name: snook. Salts pronounce its common name to rhyme with “Luke,” but from the mouths of most anglers the name rhymes with “book.” Snook range in color from amber to silver, depending on how much shrimp they’ve been eating. The snook boasts big yellowish fins. A dark lateral line streaks down the length of its body on both sides and accounts for one of its more popular aliases (linesider), while its long tapered head and underslung jaw accounts for another nickname (bucketmouth). Common at 18-35″ long but individuals may reach 55″ and weigh nearly 50 pounds. Imagine a really long bass stretched absurdly at the snout before a funhouse mirror and you have the general idea. Discovering a few years ago that a fish called snook actually lurked beneath my feet in the sulfurous mangrove estuaries, concrete canals, and dredged inlets blocks from my home was sort of like discovering that a bird named snipe existed. I had to lay eyes on that skulking bird some ten years ago in a nearby wetland—and did, and do. I had to catch this fish, but haven’t. It’s not from a lack of trying. –Snooking, Andrew Furman, Agni

YouTube might seem an unlikely venue for skeptical investigations. The online video site originated as a way for individuals to easily share videos online without having to deal with technical issues like file formats and software compatibility. YouTube gained fame through a series of “viral” videos of various ephemera such as laughing babies, stunts gone wrong, adorable kittens, and so on. It hardly seemed a good venue for skepticism in those early days. But like most new tools, uses far beyond those initially anticipated were soon discovered…. Some of the most interesting aspects of skepticism on YouTube do not come from organizations or professional skeptics but are occurring at the grassroots level between individual users. Simple, short videos debunking paranormal or pseudoscientific concepts, when created with cleverness and good visuals, can be very effective. One example, “Bigfoot Myths: Where are the Bones?” addresses the simple question: Why have we never found Bigfoot bones? –“Skepticism via YouTube,” Tim Farley, Skeptical Inquirer
