James King-Holmes/Science Photo Library Predicting natural death is generally impossible, save for those who study Caenorhabditis elegans: They know the precise moment that 131 cells, and only those 131 cells, are programmed to die. The timing and location of cell death is identical during the development of every tiny C. elegans worm. Nobel laureates John Sulston and Robert Horvitz discovered these cellular suicides in 1976 when they mapped the fate of C. elegans' 1,090 cells. "It really di

This array's dimensions are 37 x 37 x 7 mm. It can be made thinner. Proteins represent the largest class of biotech drug ap-provals, and the numbers will continue to rise as work with the human genome sequence proceeds. Figures from 2000 show that 86% of 77 approved biotech medicines are proteins, with hu

Frontlines | Physics Rules One wonders what force Dylan Thomas was pondering when he wrote: "The force that through the green fuse drives the flower/ Drives my green age." Chances are the poet wasn't considering genetics, but that shouldn't bother researchers Paul Kulesa and Scott Fraser. They've discovered that physical forces may be more important than gene expression during the development of chick somites, or embryonic segments. The prevailing view has been that molecular biology driv

Image: Erica P. Johnson Treating people who have seizure disorders is a little like playing roulette. Place a bet on a drug from column A and hope for a hit. If that drug doesn't work, try one from column B. This process can drag on for months or years, and for many people with epilepsy--between 25% and 30%--relief from seizures never comes. With 40 to 50 million people experiencing seizures worldwide, this means that huge numbers of people receive no benefit from treatment. One might think t
