...that scientists can now turn so much of their attention to the dangers of N2O is in part because CFC levels have dropped so low, thanks to the Montreal Protocol. But N2O is likely to prove much more difficult than CFCs to phase out. While CFCs had a relatively narrow range of uses - and chemical companies like DuPont were able to come up with replacements quickly - N2O is all around us, tied intimately to our industrial way of life. The millions of tons of soil fertilizer used in U.S. agriculture alone add N2O into the atmosphere, as do livestock manure...
...Paul H. Earley, medical director at Atlanta's Talbott Recovery Campus, equates abusing the drug to playing Russian roulette. "There is a very narrow window to go from feeling euphoric to be being unconscious to being unconscious and not breathing," says Earley. In a closely monitored operating theater, doctors can make quick adjustments to avoid problems. Abusers have no such recourse for a drug that acts so quickly that they often injure themselves immediately by falling. Earley says that a center that specializes in drug abuse among medical professionals started to see early signs of propofol abuse five years...

Cross streets aggressively and stare down disgruntled motorists—they’re required to stop for pedestrians in cross walks. In under five minutes, you can get from the Yard to the Law School and Hemenway Gym. Just go north, behind the Science Center, and voila. The Business School is about 20 minutes away, south of the Yard and just across the Charles. In the unfortunate event that you need to rush...
...like small departments with tiny, discussion-based seminars? Or do you like to be that one student who always speaks up during large auditorium lectures? While all concentrations will have required tutorials—smaller, narrow-topic classes that can end up being one-on-one by the time you are a senior—tutorials in larger concentrations take more of a lecture-and-section format. You won’t find much in the way of small seminars in government or economics (especially with Harvard’s budget cutting...
...This rule is especially true in higher level courses or cores where you’re assigned whole batches of academic papers or books to read each week. You almost certainly do not need to slog through it all. Narrow your focus to that which is necessary for the final/midterm/paper sweet spot, and you’ll do fine...
