Drexler, DSMZ-German Collection of Microorganism and Cell Cultures, Braunschweig, GermanyHeLa cell line infected with Mycoplasma hyorhinis. Scanning electron micrograph of critical point-dried cell culture grown on cover slips. Note the loop- and rod-like mycoplasmas attached to the host cell membrane. Smaller web-like structures on the cell surface represent microvilli of the cell. Original magnification 3,000×.Mycoplasmas have

DELETION BY DESIGN:Courtesy of Guci GiaeverThe deletion cassette module used to delete each yeast gene contains two 74-basepair tags upstream and downstream (UPTAG and DNTAG) of the KanMX gene, which confers resistance to the drug geneticin. UPTAG and DNTAG contain 18 basepairs of genomic sequence to flank the yeast's open reading frame, and U1 and U2, or D1 and D2 PCR primers for amplifying a unique 20-basepair TAG region-the so-called molecular barcode. A second round of PCR adds 45 base-pairs
For Olfaction, a Hypothesis is Felled

Peter MombaertsCourtesy of Peter MombaertsRarely do scientific studies claim that something is not the case. Rarer still do negative results appear in top-tier journals. Yet two recent papers in Nature describe what olfactory sensory neurons do not do.12The olfactory system is often compared to the immune system. The key cell types in each system, the olfactory sensory neuron (OSN) and the lymphocyte, can detect a wide variety of chemicals, both natural and synthetic. Chemical recognition by the
