Brunstetter, Duncan Matthew; Blair, David F. | Unlocking the switching of a nanomotor | Many pathogens use flagella as a means of locomotion. Pairs of Fli M residues were mutated and tested in the presence of repellent (forcing the motor to tumble) and differences in crosslinking were observed. Of those species, some (e.coli, salmonella etc.) can spin their flagella in 2 different di... | Pathogens; Flagella; Nanotechnology; Nanomotor; Trapeze Interactive Poster | 2010-03-15 |

Goller, Franz | Vocal gestures of shared syllable types in cardinals | In songbirds, songs are learned by memorization and copying of tutor song and such copies can be remarkably accurate. However, it is not known whether acoustic similarity is generated by equally similar vocal gestures. We studied syringeal and respiratory motor patterns of syllable types shared by u... | Cardinalis cardinalis; Vocal gestures; Birdsong syllables; Song syllables | 1997 |

Sperry, John S. | Water transport in vesselless angiosperms: conducting efficiency and cavitation safety | Two structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from cav... | | 2007 |
