    • Augmin : a protein complex required for centrosome-independent microtubule generation within the spindle 

      Goshima, Gohta; Mayer, Mirjam; Zhang, Nan; Stuurman, Nico; Vale, Ronald D. (Rockefeller University Press, 2008-04-28)
      Since the discovery of γ-tubulin, attention has focused on its involvement as a microtubule nucleator at the centrosome. However, mislocalization of {gamma}-tubulin away from the centrosome does not inhibit mitotic spindle ...

    • Bacterioplankton community shifts in an Arctic lake correlate with seasonal changes in organic matter source 

      Crump, Byron C.; Kling, George W.; Bahr, Michele; Hobbie, John E. (American Society for Microbiology, 2003-04)
      Seasonal shifts in bacterioplankton community composition in Toolik Lake, a tundra lake on the North Slope of Alaska, were related to shifts in the source (terrestrial versus phytoplankton) and lability of dissolved organic ...
    • Baleen whales are not important as prey for killer whales Orcinus orca in high-latitude regions 

      Mehta, Amee V.; Allen, Judith M.; Constantine, Rochelle; Garrigue, Claire; Jann, Beatrice; Jenner, Curt; Marx, Marilyn K.; Matkin, Craig O.; Mattila, David K.; Minton, Gianna; Mizroch, Sally A.; Olavarría, Carlos; Robbins, Jooke; Russell, Kirsty G.; Seton, Rosemary E.; Steiger, Gretchen H.; Víkingsson, Gísli A.; Wade, Paul R.; Witteveen, Briana H.; Clapham, Phillip J. (Inter-Research, 2007-10-25)
      Certain populations of killer whales Orcinus orca feed primarily or exclusively on marine mammals. However, whether or not baleen whales represent an important prey source for killer whales is debatable. A hypothesis by ...
    • Barnegat Bay-Little Egg Harbor Estuary : case study of a highly eutrophic coastal bay system

      The Barnegat Bay-Little Egg Harbor Estuary is classified here as a highly eutrophic estuary based on application of NOAA’s National Estuarine Eutrophication Assessment model. Because it is shallow, poorly flushed, and ...
    • Bcl-xL regulates metabolic efficiency of neurons through interaction with the mitochondrial F1FO ATP synthase 

      Alavian, Kambiz N.; Li, Hongmei; Collis, Leon P.; Bonanni, Laura; Zeng, Lu; Sacchetti, Silvio; Lazrove, Emma; Nabili, Panah; Flaherty, Benjamin; Graham, Morven; Chen, Yingbei; Messerli, Shanta M.; Mariggio, Maria A.; Rahner, Christoph; McNay, Ewan; Shore, Gordon; Smith, Peter J. S.; Hardwick, J. Marie; Jonas, Elizabeth A. (2011-06)
      Anti-apoptotic BCL-2 family proteins such as Bcl-xL protect cells from death by sequestering apoptotic molecules, but also contribute to normal neuronal function. We find in hippocampal neurons that Bcl-xL enhances the ...
