The orientation of swimming bi-flagellates in shear flows [PDF]
, 2012 Biflagellated algae swim in mean directions that are governed by their environments. For example, many algae can swim upward on average (gravitaxis) and toward downwelling fluid (gyrotaxis) via a variety of mechanisms.

Analytical approximations for the orientation distribution of small dipolar particles in steady shear flows [PDF]
, 1998 Analytic approximations are obtained to solutions of the steady Fokker-Planck equation describing the probability density functions for the orientation of dipolar particles in a steady, low-Reynolds-number shear flow and a uniform external field.

Glyphosate perturbs the gut microbiota of honey bees
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Increased mortality of honey bee colonies has been attributed to several factors but is not fully understood. The herbicide glyphosate is expected to be innocuous to animals, including bees, because it targets an enzyme only found in plants ...

The interaction of thin-film flow, bacterial swarming and cell differentiation in colonies of Serratia liquefaciens [PDF]
, 2000 The rate of expansion of bacterial colonies of S. liquefaciens is investigated in terms of a mathematical model that combines biological as well as hydrodynamic processes. The relative importance of cell differentiation and production of an extracellular

Nature, 1906 UP to the beginning of 1905, 224 species of wild bees had been recorded from Australia, no less than 183 of them having been described by F. Smith, of the British Museum. I had the opportunity in 1904 to study Smith's types at the British Museum, and since then I have worked up the unnamed Australian material belonging to that institution, with the ...
