Isolation and characterization of motility-defective mutants of Haloferax volcanii.
Haloferax volcanii is a motile extreme halophile, and a detailed physical map of its genome exists. An effort is underway to locate more genes and to increase the detail of this map. Flagellated motile bacteria possess a number of filaments that function as cellular propellers. Motile bacteria swim …

Distribution and structure of ocelli in Lepidoptera previously reported to be anocellate and morphology of a nerve complex associated with the ocelli
… The structure of internal ocelli is examined by light and electron microscopy. A unique circular rhabdom apparently composed of a single retinular cell was observed in the internal ocelli of sphingids. Pigment cells were found to be absent. Observations were also made on the synapse between first …
