LilaG writes "Drug tests spot banned substances based on their chemical structures, but a new breed of narcotics is designed to evade such tests. These synthetic marijuana drugs, found in 'herbal incense,' are mere chemical tweaks of each other, allowing them to escape detection each time researchers develop a new test for one of the compounds. Now chemists have developed a method that can screen for multiple designer drugs at once, without knowing their structures. The test may help law enforcement crack down on the substances. The researchers used a technique called 'mass defect filtering,' which can detect related compounds all at once. That's because related compounds have almost equal numbers to the right of the decimal point in their molecular masses. The researchers tested their technique on 32 herbal products ... They found that every product contained one or more synthetic cannabinoid; all told, they identified nine different compounds in them — two illegal ones and seven that are not regulated. The original paper appears (behind a paywall) in Analytical Chemistry."
From the article: "The research is timely, too. 'Many drugs of abuse in the Olympics are designer drugs,' he [Gary Siuzdak] says, in the steroid family. Grabenauer plans to extend her method to other designer drug families."Read Replies (0)

writes "In Digital Vertigo: How Todays Online Social Revolution Is Dividing, Diminishing, and Disorienting Us, author Andrew Keen, who describes himself as the Anti-Christ of Silicon Valley (whatever that means), raises numerous profound questions about social media and its implications on society. In the new world of social media and Web 3.0, which is claiming to revolutionize communication and interactions, Keen writes that history is repeating itself and points to the beginning of the industrial revolution as an example. He writes of Jeremy Bentham who invented the Panopticon; a structure where the inhabitants were watched at all times. Bentham felt the Panopticon could make humanity more virtuous, more hard-working and happier; similar to the promise of Web 3.0. The Panopticon was a failure, and Keen sees the same for Web 3.0. The book is a critique of Web 3.0."
