...China's powerful strain of export-led growth. Moreover, to the extent that its currency-management objectives required ongoing recycling of a massive reservoir of foreign-exchange reserves into U.S. dollar - based assets, such capital inflows helped keep longer-term U.S. interest rates at exceptionally low levels. In effect, China's implicit interest-rate subsidy ended up becoming an important prop to bubble-prone U.S. asset markets and, ultimately, for the asset-dependent American consumer...
...Until then, researchers have only some intriguing and, frankly, puzzling snippets of information--and plenty of questions. The trial actually tested two vaccines: one that primes the immune system by training cells to recognize and destroy the virus and one that boosts that response. Neither shot has proved effective alone, yet together they seemed to trigger a modest immunity--although no one yet knows why. Fifty-one people who received the vaccine became infected with HIV, compared with 74 who received a saltwater placebo, a barely significant difference. And while a lower risk of infection normally derives from a drop...

That the Web is full of misinformation is irrefutable, but Sunstein's case for toughening libel laws and educating consumers on how information spreads (which he approvingly predicts would have a chilling effect) will most likely provoke debate--especially given the legal scholar's new role as head of the White House Office of Information and Regulatory Affairs...

...IPCC's predictions are grim for a country that still hasn't figured out an effective strategy for water management. In the northwest alone, the water table is falling by about 1.6 inches per year, according to the GRACE (Gravity Recovery and Climate Experiment) mission. At least half of India's precipitation comes from the annual monsoon rains, and as they become increasingly diminished and unpredictable, the country faces an imminent threat of extreme water shortages. Changing rainfall patterns aren't the only climate- change effect threatening India's water supply: Himalayan glaciers - the source for the many Indian rivers...
