...lice becoming hardier? According to TIME medical reporter Janice Horowitz, the Harvard study results revealed a correlation between over-treatment and resistance. "The researchers looked at kids in two American cities, Boise and Boston, and compared them with kids with lice in Borneo. In Borneo, where few or no pesticides are used, lice were killed very quickly by an application of permethrin. In Boise and Boston, the lice were far more resistant to the pesticide, having been exposed to the chemicals before." Horowitz notes that an increased dose of the lice-killer in Borneo destroyed the parasites faster, whereas...
...medicine has made so many gains against maladies far more serious than lice. Why, 20 years ago, a bottle of Kwell, a hot dryer and a good cleaning did the job. But today's louse, a.k.a. Pediculus humanus capitis, which nests in 12 million new heads annually, is a hardier bug, having grown resistant to the prescription drugs lindane and Elimite and the over-the-counter permethrin drug Nix, which remain imperfect mainstays in the treatment of lice. "The pyrethrins [RID, Pronto and A-200 Pyrinate] aren't working as well as they used to either," says University of Miami...
...from necessary economic reforms. At worst, the West could eventually be confronted with a China-led belligerent East -? and new Cold War for the 21st century. At best?

...good one, but time and again it failed--just as it had failed for other scientists who had tried similar methods. On one trial, however, the Atlanta team happened to extract the eggs on the eighth day of the hormone regimen rather than the 10th. When these younger, presumably hardier ova were frozen and thawed, they emerged from the process intact. "It was more a matter of timing than anything else," says Michael Tucker, scientific director...
