...roads, Hoffrichter and Provis (partners on the 4 p.m.-to-midnight shift) are alert but not alarmed.

A bin outside their hut overflows with confiscated produce; statewide, 45,000 kg were collected in the past six months. The low-tech operation is winning the war for South Australia's $250 million fruit and vegetable industry. "We're the only state free of fruit fly," says...

They crawl out, let out a bit of silk and float away...
...get around political roadblocks, scientists are searching for another source of cells that is less ethically troublesome, ideally one that involves no embryo destruction at all. One approach is "altered nuclear transfer," in which a gene, known as CDX2, would be removed before the cell is fused with the egg. That would ensure that the embryo lives only long enough to produce stem cells and then dies. That strategy, promoted by Dr. William Hurlbut, a member of the President's Council on Bioethics, has its critics. Dr. Robert Lanza of biotech firm Advanced Cell Technology considers it unethical to deliberately...
NUCLEAR-TRANSFER EMBRYOS Why they are useful These embryos are created using the technique that created Dolly, the cloned sheep. Stem cells can be custom-made by inserting a patient's skin cell into a hollowed human egg. Any resulting therapies would not run the risk of immune rejection...
