...Tononi and a growing number of other scientists believe that sleep - not just in flies but also in higher-order mammals - may perform such a pressure-releasing role. During sleep, researchers theorize, the brain actively prunes the neural network laid out during waking hours, trimming away weaker connections that haven't been used in a while or weren't strong enough to begin with. The stronger connections are believed to be filed during sleep into long-term memory, where they can be accessed again and again as needed. All this nocturnal tidying creates room for new connections to be formed...
...That makes sense for a human. But exactly how much new information does a fruit fly acquire in a day? How complex could Drosophila's world be that it actually needs shut-eye to recharge its brain? You'd be surprised. For a fly, its brief, two-month life can only be about mating and eating - or eating and mating, depending on whether mates or food are in shorter supply - but these activities involve complex social interactions that, frankly, can be exhausting...
...Answering that question won't be easy. While there are clear benefits to starting anti-HIV medicines early in the progression of the disease, the drugs are not without side effects. Some studies have noted increased risk of certain cancers as well as toxic effects to the brain and other organs over the long term. "The real critical issue that everyone is struggling with is, What about the potential long-term deleterious effects of ART that might override the beneficial effects?" says Fauci...
...many to sign up after 9/11 is now eight years past. That leaves recruiters with perhaps the toughest, if not the most dangerous, job in the Army. Last year alone, the number of recruiters who killed themselves was triple the overall Army rate. Like posttraumatic stress disorder and traumatic brain injury, recruiter suicides are a hidden cost of the nation's wars...
...previous voting records of their neighbors and noted that a follow-up would be sent indicating who voted this time. (The Obama campaign actually priced out a similar mailer but decided not to risk a backlash.) And shame works; even some AIG executives gave up bonuses. Cialdini says brain imaging shows that when we think we're out of step with our peers, the part of our brain that registers pain shifts into overdrive. "It's an incredibly powerful spur to action," he says. (See 25 people to blame for the financial crisis...
