Those genes hardly exhaust the list of possibilities. Among the suspects are virtually all the genes that control brain development and perhaps cholesterol and immune-system function as well. Christopher Stodgell, a developmental toxicologist at New York's University of Rochester, observes that the process that sets up the brain resembles an amazingly intricate musical score, and there are tens of thousands of genes in the orchestra. If these genes do what they're supposed to do, says Stodgell, "then you have a Mozart's Concerto for Clarinet. If not, you have cacophony...
...threat from the mercury has spread beyond the villages around the mining site. The processing units are highly mobile, with some located as far as 50 km away, says Rini Sulaiman, an environmental toxicologist with the U.S.-funded National Resources Management Program. And that, says Daniel Limbong, means the mercury contamination will eventually threaten the 400,000 people living in Manado. It could be happening already. According to Limbong, samples taken from sediment in the estuary of the Talawaan river where it empties in Manado Bay are almost at the levels seen in samples taken where the river passes...
Surrounded by his famous collection of time pieces, Judge Lance Ito is clearly impatient with the pace of the Simpson trial. In a serious setback for the defense, Ito ruled that he will not allow the testimony of disgruntled FBI agent Frederic Whitehurst. The decision also means that FBI toxicologist and former prosecution witness Roger Martz will not have to return to the stand. James Willwerth reports from the trial: "Ito ruled that it was not relevant for jurors to hear Whitehurst saying he believed that Martz had altered lab results in another case, testimony the defense hoped...
...blood found on a sock inO.J. Simpson's bedroom and on a gate at the murder scene planted by police? Witnesses for the O.J. Simpson defense can't agree on the razor-thin strand of evidence that might support such a claim. Monday, Fredric Rieders, a forensic toxicologist, testified that the blood apparently contained EDTA, a chemical preservative used in crime analysis, which suggested that the blood could have been planted by someone with access to samples from the victims and the defendant. Today, FBI Special Agent Roger Martz -- who performed the analysis of the blood -- said Rieders essentially misrepresented...
...these reports involve heavy doses of chemicals, evidence from laboratory studies suggests there are also effects at lower concentrations. Endocrinologist David Crews has discovered, for example, that small PCB doses can dramatically influence the ratio of male to female offspring in red-eared slider turtles. When University of Wisconsin toxicologist Richard Peterson investigated the impact of dioxin on male rats, he found that the dose needed to cause reproductive-system problems was relatively high. "But when we exposed pregnant rats to a dose 1/100th as large," he says, "we found the male offspring showed signs of reproductive dysfunction," including smaller...
