What the data say By Kerry Grens ARTICLE EXTRAS Feature Article 3,7 The gel does not indicate the subunit gene for which the primers were designed, although the gene for chain 1 of Fel d 1 is 1.7 kb (GenBank accession number X62477). Chain 2 is 2.4 kb (GenBank accession number X62478). Microbac's genetic analysis concludes, however, that mutations found in chain 1 "are

Bioterror has been a serious threat, and you wonder if maybe that cloud is full of pathogens, or perhaps it's just going to rain. Better not take a chance: You reach for your stash of Hemopurifiers, clasp one to your belt, plug it into your blo

So the animal communication researcher came up with the obvious choice: condoms. In 2000, Narins, a professor at the University of California, Los Angeles, and his colleagues at the University of Vienna glued a condom to the jaw

Although she was an environmental scientist, Snyder didn't really know anything about sludge, but the story piqued her interest because she had recently retired to New Hampshi

(Cited in 68 papers) The finding: A team of Finnish and US researchers, led by University of Michigan professor Michael Boehnke, found that several single nucleotide polymorphisms (SNPs) around the transcription factor, hepatocyte nuclear factor-4á (HNF4A), were associated with dia
