...sounds simple. But this reverse-engineering approach, finding inspiration for new vaccines by studying HIV immunity in nature, would have been impossible back in 1984 - or, indeed, until just a few years ago. Too little was known about the virus's structure or about the human immune system in general. One recent necessary breakthrough, Nussenzweig says, was finding a way to identify the blood cells that create HIV-specific antibodies. It was only after those cells could be separated from the bloodstream that scientists like Nussenzweig and Johannes Scheid, the first author on the Nature paper, could begin to study...
...other writers say, goes back to the mid-'90s, when the bulletin-board system, or BBS, first appeared on the Chinese Internet as a platform to share opinions and in many cases literary creations. "I still recall my astonishment when I read my first online novel some 15 years ago on a BBS," says Zhang Kangkang, a renowned novelist and vice chairwoman of the Chinese Writers Association.

...Israelis how long it has been since Corporal Gilad Shalit was captured by Palestinian militants in Gaza, and they'll know exactly. On Monday, it was 995 days ago.

...ended abruptly last year and is now unwinding. Deflation is evident in Beijing and Shanghai in particular, where real estate developers and brokers report prices will likely be down 15% to 20% this year. Prices in the once booming city of Shenzhen are down more than 18% from year-ago levels. Nationwide, according to a recent forecast by economists at the Chinese Academy of Social Sciences, housing prices in China may decline 10% to 15% this year, as the overall economy struggles amidst the global financial crisis. "Housing prices far surpassed the actual incomes of the general public" over...
Consider recent apartment buyer Hong Chang-Ying, who owns and runs a small electronics store in central Shanghai. She bought her apartment in Shanghai three years ago for the equivalent of about $80,000, and was "sure she could sell it by now at a profit, and buy a bigger place." Ask her if that plan still holds, and she just laughs. "I have no idea now what my place is worth now - and I don't intend to find out, because I'm not going to sell into this market." China may not confront the disastrous effect that huge...
