    • Adaptation at the output of the chemotaxis signalling pathway 

      Yuan, Junhua; Branch, Richard William; Hosu, Basarab Gabriel; Berg, Howard Curtis (2012)
      In the bacterial chemotaxis network, receptor clusters process input1–3, and flagellar motors generate output4. Receptor and motor complexes are coupled by the diffusible protein CheY-P. Receptor output (the steady-state ...
    • Dynamics of Mechanosensing in the Bacterial Flagellar Motor 

      Lele, Pushkar Prakash; Hosu, Basarab Gabriel; Berg, Howard Curtis (Proceedings of the National Academy of Sciences, 2013)
      Mechanosensing by flagella is thought to trigger bacterial swarmer-cell differentiation, an important step in pathogenesis. How flagellar motors sense mechanical stimuli is not known. To study this problem, we suddenly ...
    • 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 ...
    • Osmotic Pressure in a Bacterial Swarm 

      Ping, Liyan; Wu, Yilin; Hosu, Basarab Gabriel; Tang, Jay Xin; Berg, Howard Curtis (Elsevier BV, 2014)
      Using Escherichia coli as a model organism, we studied how water is recruited by a bacterial swarm. A previous analysis of trajectories of small air bubbles revealed a stream of fluid flowing in a clockwise direction ahead ...
    • Reversible Disassembly of the Actin Cytoskeleton Improves the Survival Rate and Developmental Competence of Cryopreserved Mouse Oocytes 

      Hosu, Basarab Gabriel; Mullen, Steven F.; Critser, John K.; Forgacs, Gabor; Steinhardt, Richard (Public Library of Science, 2008)
      Effective cryopreservation of oocytes is critically needed in many areas of human reproductive medicine and basic science, such as stem cell research. Currently, oocyte cryopreservation has a low success rate. The goal of ...
