...arguments against long-term handouts of food - dependency, corruption, the disincentive effect, a tendency for outside shocks to be exaggerated in a country with little capacity to plan for them - are well known. Africa provides arresting proof of their validity. Today the continent can no longer feed itself, and its share of world agricultural trade is much less than it was two generations ago. Globalization of agriculture - a process as old as sailing ships - means products that originated in Africa are now grown elsewhere. Coffee came from Ethiopia; Vietnam now grows more than all Africa.

...equipped cell phones being operated with lopped-off fingers. "No system would fly if part of your anatomy is threatened and is necessary to secure what could be substantial assets," says Scott. So the sensor in the phone doesn't merely read a static fingerprint. It also looks for proof of life--blood flow, tissue elasticity and capillary structure. It also uses an anxiety index being developed by the University of Michigan medical school to measure stress-induced, minute changes in capillaries and sweat glands. "If someone puts a gun to your head, the transaction won't occur, and people...
...treatments at all - a fairly high nonresponder rate. Researchers don't yet know how to explain those failures. One inherent stumbling block is that a male contraceptive must block millions of sperm, as opposed to a single egg. (The Pill had it easy.) Another is race: according to several proof-of-concept studies, Asian men maintained a suppressed sperm count with greater frequency than Caucasians, but researchers still don't know...
...parts of Europe, seeking to escape Nazi persecution. Rather less known is the exodus of 30,000 Jews eastward - to Shanghai.

And while historical proof of the cosmopolitan nature of prewar Shanghai is everywhere, this 100-year-old building is among the more intriguing...
...over ideology--and a victory for Rice and her diplomatic team over the neoconservatives led by Vice President Dick Cheney. Since Rice took the helm at State in 2005, she has steadily consolidated her authority over foreign policy. If her clout isn't absolute, it is approaching the veto-proof swat that Cheney enjoyed as the secret vicar of national security...
