    • Adaptive Remodelling by FliN in the Bacterial Rotary Motor 

      Branch, Richard; Sayegh, Michael; Shen, Chong; Nathan, Vedavalli S.J.; Berg, Howard Curtis (Elsevier BV, 2014)
      Sensory adaptation in the Escherichia coli chemosensory pathway has been the subject of interest for decades, with investigation focusing on the receptors that process extracellular inputs. Recent studies demonstrate that ...

    • Following the Behavior of the Flagellar Rotary Motor Near Zero Load 

      Yuan, Junying; Berg, Howard (Springer Verlag, 2009)
      At room temperature at stall, the flagellar motor of the bacterium Escherichia coli exerts a torque of ~1300 pN nm. At zero external load, it spins ~330 Hz. Techniques for studying the motor near zero load are novel and ...

    • Microbubbles Reveal Chiral Fluid Flows in Bacterial Swarms 

      Wu, Yilin; Hosu, Basarab Gabriel; Berg, Howard Curtis (National Academy of Sciences, 2010)
      Flagellated bacteria can swim within a thin film of fluid that coats a solid surface, such as agar; this is a means for colony expansion known as swarming. We found that micron-sized bubbles make excellent tracers for the ...

    • The Upper Surface of an Escherichia Coli Swarm Is Stationary 

      Zhang, Rongjing; Turner, Linda; Berg, Howard Curtis (National Academy of Sciences, 2010)
      When grown in a rich medium on agar, many bacteria elongate, produce more flagella, and swim in a thin film of fluid over the agar surface in swirling packs. Cells that spread in this way are said to swarm. The agar is a ...
