...dopamine levels high by inhibiting the activity of a transporter molecule that would ordinarily ferry dopamine back into the cells that produce it. Nicotine, heroin and alcohol trigger a complex chemical cascade that raises dopamine levels. And a still unknown chemical in cigarette smoke, a group led by Brookhaven chemist Joanna Fowler reported last year, may extend the activity of dopamine by blocking a mopping-up enzyme, called MAO B, that would otherwise destroy...
This Whitehurst guy is Frederic Whitehurst, the FBI chemist who originally blew the whistle on the FBI lab in 1989 and helped launch an inquiry that finally resulted last week in a blistering report from the Justice Department's inspector general. Michael Bromwich released a 600-page doorstop charging that some FBI forensic operations had been sloppy and biased. But even before the verdict was reached, Whitehurst's treatment as a whistle-blower raised questions about the FBI's ability to manage dissent. At first, lab managers dismissed his complaints about colleagues' work as prickly perfectionism. They suspended...
...have triggered a staff shake-up. On Jan. 20 the Justice Department gave FBI officials a preliminary report that found errors, sloppiness and poor management in the agency's crime lab. The investigation had its origins in charges made since the mid-1980s by Frederic Whitehurst, a senior chemist. The report is still secret, but Justice and FBI officials say that while it found nothing illegal, it did identify some serious lapses. FBI Director Louis Freeh has already launched reforms. Meanwhile, the agency announced that three bomb investigators have been removed from their positions and that Whitehurst has been suspended...
Justice Department prosecutors say they have known for months that Williams would receive harsh criticism, and had long since decided against having him testify. Instead they will call Steven Burmeister, a chemist praised in the report as meticulous, and Linda Jones, a British explosives expert. Burmeister performed the tests that showed traces of an explosive on McVeigh's clothing. He found no evidence that the clothes had been mishandled, the officials say. They acknowledge that some debris may have been contaminated, but they say that these were never intended to be used as evidence. All very reasonable, perhaps...
...grappling with similar suits brought by thousands of women. One reason: Jones took the unusual step of appointing four independent experts to assess the purported link between the rupture of silicone implants and specific physical complaints. These experts--an immunologist, an immunologist/toxicologist, a rheumatologist and a polymer chemist--arrived at the same conclusion reached by many others, including Dr. Marcia Angell, executive editor of the New England Journal of Medicine: localized problems, notably the painful hardening of breast tissue, can accompany implants, but as yet no compelling evidence links the leakage of silicone gel to more debilitating disease. "This...
