...income brackets. Moreover, 46 percent of those test-takers scoring over 1420 came from families in the top quintile in income level. Critics of the current SAT believe this demonstrates the degree to which test scores are determined by background and preparation. In fact, this does not actually explain the numbers. A 2005 College Board survey found that, on average, SAT tutoring raised verbal scores a mere 10 points and math scores only about 15-20 points. This is hardly a mind-blowing difference...
...results can vary, and quite significantly. The Rochester study, for example, happened to look at the effectiveness of a vaccine during two seasons in which the flu strain included in the vaccine was not well matched to the predominant circulating strain that was making people sick. That could explain the lack of protection among the vaccinees - the shot may have been protecting against the wrong flu proteins. Targeting the correct strain is a always a bit of a guessing game, however; researchers make their best scientifically based prediction as to which flu virus will be making the rounds...
...will help us probe what the universe was like just moments after the Big Bang. It might explain why more than 95 percent of the stuff out there is actually invisible. And it could lead to technological breakthroughs years from now. Plus, with all the low hanging fruit in physics already picked, scientists need expensive technology to continue delving into the secrets of the universe. Clocks, pendulums, and oil drops just don’t cut it in the 21st century...
Such stories help explain an interesting feature of transgender life: men who want to change outward gender wait an average of 10 years longer to transition than women, according to the new article by Schilt and Wiswall. "MTFs attempt to preserve their male advantage at work for as long as possible," they write, "whereas FTMs may seek to shed their female gender identity more quickly." It should be noted that many transgender men do experience discrimination, especially if they are short and if they don't look convincingly male. Also, it's harder for MTFs to pass than FTMs...
...condition of anonymity, made clear that they shared the suspicion that the tanks were destined for south Sudan, where Kenya has supported a secessionist resistance movement oppossed to the northern Sudanese-dominated government in Khartoum. The fact that such a shipment might contravene international arms embargoes might help explain why the Faina, traveling with minimal security on board, presented itself as an unremarkable cargo freighter - to fool officials along its route as well as pirates. Of more concern to East Africa's regional security, recent reports from north and south Sudan have suggested both sides are currently re-equipping their...
