    High resolution study of anion formation in low-energy electron attachment to SF6 molecules in a seeded supersonic beam

    Using two variants of the Laser Photoelectron Attachment (LPA) method involving a differentially-pumped, seeded supersonic beam (0.05% and 12.5% of SF6 molecules in helium carrier gas, nozzle temperatures T0= ...

    Osteoblastic cells regulate the haematopoietic stem cell niche

    Stem cell fate is influenced by specialized microenvironments that remain poorly defined in mammals1,2,3. To explore the possibility that haematopoietic stem cells derive regulatory information from bone, account...

    Evolution of the Hemaggllutinin Gene of Influenza B Virus was Driven by Both Positive and Negative Selection Pressures

    Nucleotide sequences of the hemagglutinin (HA) gene of twelve influenza B strains and their deduced amino acid sequences were extracted from the GenBank and compared to those of early isolates. Separate analys...

    Isolation of isoflavones from soy-based fermentations of the erythromycin-producing bacterium Saccharopolyspora erythraea

    A search for an abundant and economical source of isoflavones, particularly genistein, led to the discovery that the erythromycin-producing organism Saccharopolyspora erythraea also produces this promising new c...

    Rydberg electron transfer to C60 and C70

    Experimental results are reported for the attachment of Ar* * (nl) Rydberg electrons to C60 and C70 over the range n = 19–270. In agreement with other Rydberg work we find that the rate coefficient for C ...
