...Most research into fish sex determination has been done in the lab (for obvious reasons), but the pejerrey is one of the few species that scientists have been able to study in the field. And those studies have revealed that already, its proportion of males to females is skewed. "It could be because of chemical pollution or it could be because of climate change. We don't know," cautions Piferrer. "But the field data matches our predictions...
...headphones. It's all dictated by the level of background noise in their listening environment. When we put people in different listening environments, like flying in an airplane - we used noise we'd recorded while flying on a Boeing 757 commercial flight, and we simulated that environment in our lab - 80% of people listened at levels that would eventually put their hearing at risk. On the subway system here in Boston, the ambient noise levels are very comparable to the level on an airplane, although it sounds very different. The noise is sufficiently high that it induces people to listen...
Cell-phone broadcasting has caught on in some unexpected places. Republican Congressman John Culberson of Texas recently filmed and broadcast 25 Qik videos, including one meta-video: live footage of the Phoenix Mars landing from the Jet Propulsion Lab control room in Pasadena, Calif. H2o News, which broadcasts events for the Vatican, has streamed dozens of Qik videos so far, including some documenting the Pope's travels. But even for more mundane occasions, Qik's early fans say it's satisfying to know you could broadcast anything to anyone in the world at a second's notice should the need...
...objective is to standardize methods for validating genetic tests and guaranteeing accuracy and quality, says Mari Baker, CEO of California-based Navigenics. For now, all clinical labs, including those that conduct genetic tests, are regulated by the Centers for Medicare and Medicaid Services, which, under the federal Clinical Laboratory Improvement Amendments (CLIA), governs lab-personnel qualifications, quality-control procedures and proficiency testing. But critics argue that the law needs to be updated to include standards for genetic-testing labs. CLIA requires independent evaluations of labs' test-performance proficiency, for example, but genetic-testing labs are exempt from this rule, according...
...after receiving complaints from consumers, the California Department of Health sent cease-and-desist letters to 13 companies, including deCODE Genetics, 23andMe and Navigenics, asking them to stop doing business with California customers until they could prove they were complying with state laws. In California, only physicians may order lab tests, and all labs must obtain a state license and meet federal CLIA requirements. Last November, New York State's Department of Health mailed similar letters to 31 companies. (Navigenics and 23andMe have since submitted business plans to New York for approval.) "Our priority is to protect the health...
