They stumbled toward the riverbanks, some crying out, "Mizu, mizu!" (Water, water); the temperature and their injuries had left them severely dehydrated. Because light colors reflect heat and dark ones absorb it, some bomb victims had the images of their clothing tattooed on their flesh: the pattern of a kimono on a woman's back, the unburned swath left by a sash around the waist of an otherwise charred man. "Big black flies appeared and tried to lay eggs on human flesh," says survivor Michiko Watanabe, now 65. "The injured were so weak that they couldn't brush away...
What about side effects? Injections of leptin do not, as one might fear, turn lean mice into starving wretches. After losing weight, researchers from Amgen reported, normal mice stabilize both their food intake and their metabolism. Obese mice likewise reach an optimal leanness, then stop losing weight. The pattern of weight loss is also encouraging. For unlike extreme calorie restriction, which can weaken muscle, leptin appears to dissolve fat while leaving lean tissue intact. On the basis of such data, Amgen (which paid Rockefeller University $20 million for patent rights to make products based on the ob gene) has announced...
...straight out of the leg, proceeding from the ankle out, but develop in a fanlike progression that runs from the smallest digit to the largest. In Geneva, Duboule and his colleagues tracked the activity of four Hox genes in the budding feet of embryonic mice and found precisely this pattern. By contrast, studies showed that in the zebrafish, the Hox genes switch off earlier, perhaps to ensure that a flexible fin ray (useful for swimming) will form in the place of feet. Duboule speculates that if these genes could be tricked into staying on just a bit longer, the fins...
Retaliation is something of a pattern within the ATF, according to a recent internal investigation by the Treasury Inspector General's office. In a report sent to Magaw last year, the investigators said they found that of 370 Equal Employment Opportunity complaints filed by employees, 105 resulted in charges being filed with Internal Affairs against the complainers or their supporting witnesses. In 54 of these cases, Internal Affairs launched full investigations. The report cited an array of management practices that "created at least a perception among some ATF employees that managers abused their authority by retaliating, harassing or intimidating...
...China sees a pattern that may not in fact exist. The Clinton foreign policy in general is somewhat ad hoc and driven by politics. The approach to China is no different, but Beijing sees something more systematic and more sinister. "In China, more and more people are wondering, What are the Americans up to?" says Cui Liru, a scholar at the China Institute of Contemporary International Relations in Beijing. "Quite a number believe the Americans regard a powerful China as a hindrance to the U.S. in its bid to maintain world dominance, and so are trying hard to keep China...
