      Fiore, Arlene M.; Jacob, Daniel James; Bey, Isabelle; Yantosca, Robert M.; Field, Brendan; Fusco, Andrew; Wilkinson, James (Wiley-Blackwell, 2002)
      Observations indicate that ozone (O3) concentrations in surface air over the United States in summer contain a 20–45 ppbv background contribution, presumably reflecting transport from outside the North American boundary ...

      Potsdam, Eric; Polinsky, Maria (Wiley Blackwell (Blackwell Publishing), 2012)
      This paper documents and analyzes an instance of covert A-movement, specifically covert subject-to-subject raising, in the Northwest Caucasian language Adyghe. We argue that Adyghe has a subject-to-subject raising ...
    • Bacteria activate sensory neurons that modulate pain and inflammation 

      Chiu, Isaac M.; Heesters, Balthasar A.; Ghasemlou, Nader; Von Hehn, Christian A.; Zhao, Fan; Tran, Johnathan; Wainger, Brian; Strominger, Amanda; Muralidharan, Sriya; Horswill, Alexander R.; Wardenburg, Juliane Bubeck; Hwang, Sun Wook; Carroll, Michael C.; Woolf, Clifford J. (2013)
      Summary Nociceptor sensory neurons are specialized to detect potentially damaging stimuli, protecting the organism by initiating the sensation of pain and eliciting defensive behaviors. Bacterial infections produce pain ...
    • Bacteria Pattern Spontaneously on Periodic Nanostructure Arrays 

      Hochbaum, Allon I.; Aizenberg, Joanna (American Chemical Society (ACS), 2010)
      Surface-associated bacteria typically form self-organizing communities called biofilms. Spatial segregation is important for various bacterial processes associated with cellular and community development. Here, we demonstrate ...
    • Bacterial biofilm shows persistent resistance to liquid wetting and gas penetration 

      Epstein, A. K.; Pokroy, B.; Seminara, A.; Aizenberg, Joanna (Proceedings of the National Academy of Sciences, 2010)
      Most of the world’s bacteria exist in robust, sessile communities known as biofilms, ubiquitously adherent to environmental surfaces from ocean floors to human teeth and notoriously resistant to antimicrobial agents. We ...
    • The Bacterial Carbon-Fixing Organelle Is Formed by Shell Envelopment of Preassembled Cargo 

      Chen, Anna H.; Robinson-Mosher, Avi; Savage, David F.; Silver, Pamela A.; Polka, Jessica K. (Public Library of Science, 2013)
      Background: Cyanobacteria play a significant role in the global carbon cycle. In Synechococcuselongatus, the carbon-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is concentrated into polyhedral, ...
    • Bacterial chemotaxis and the question of gain 

      Sourjik, Victor; Berg, Howard C. (National Academy of Sciences, 2002)
      Chemoreceptors in Escherichia coli are coupled to the flagella by a labile phosphorylated intermediate, CheYsimilar toP. Its activity can be inferred from the rotational bias of flagellar motors, but motor response is ...
    • Bacterial Coexistence Driven by Motility and Spatial Competition 

      Gude, Sebastian; Pinçe, Erçağ; Taute, Katja; Seinen, Anne-Bart; Shimizu, Thomas S.; Tans, Sander J. (Springer Science and Business Media LLC, 2020-02)
      Elucidating elementary mechanisms that underlie bacterial diversity is central to ecology and microbiome research. Bacteria are known to coexist by metabolic specialization, cooperation, and cyclic warfare. Many are also ...
    • A bacterial cytidine deaminase toxin enables CRISPR-free mitochondrial base editing 

      Mok, Beverly Y.; de Moraes, Marcos H.; Zeng, Jun; Bosch, Dustin E.; Kotrys, Anna V.; Raguram, Aditya; Hsu, FoSheng; Radey, Matthew C.; Peterson, S. Brook; Mootha, Vamsi K.; Mougous, Joseph D.; Liu, David (Springer Science and Business Media LLC, 2020-07-08)
    • Bacterial Diversity across Individual Lichens 

      Mushegian, A; Peterson, Celeste; Baker, Christopher Cher Meng; Pringle, Anne E. (American Society for Microbiology, 2011)
      Symbioses are unique habitats for bacteria. We surveyed the spatial diversity of bacterial communities across multiple individuals of closely related lichens using terminal restriction fragment length polymorphism (T-RFLP) ...
    • Bacterial Flagella Are Firmly Anchored 

      Darnton, Nicholas C.; Berg, Howard C. (American Society for Microbiology, 2008)
      There are mutants of Salmonella enterica (with mutations in fliF and fliL) that shed flagella when they are swimming in a viscous medium or on the surface of soft agar. Filaments with hooks and the distal rod segment FlgG ...
