Biomolecules inside a microfluidic system can be used to solve computational problems, such as theorem proving, which is an important class of logical reasoning problems. In this article, the Boolean variables (literals) were represented using single-stranded DNA molecules, and theorem proving was performed by the hybridization and ligation of these variables into a double-stranded ‘‘solution’’...

Theodor Kocher (1841-1917)--a surgical maestro.

Accessible online at: www.karger.com/journals/dsu The name Theodor Kocher (fig. 1) is obviously known to surgeons working not only in his hometown Bern, Switzerland, but also in the rest of the world. Outside Bern, probably, his name today is usually connected to ‘the Kocher maneuver’, or to some instrument, rather than to the 1909 Nobel laureate. Bern’s doctors and surgeons are proud of Theodo...

Brownell-BIOCOCHLEA.doc 1/31/2003 10:08 AM 169 MEMBRANE ELECTROMECHANICS AT HAIR-CELL SYNAPSES

Both outer hair cell electromotility and neurotransmission at the inner hair cell synapse are rapid mechanical events that are synchronized to the hair-cell receptor potential. We analyze whether the forces and potentials resulting from membrane flexoelectricity could affect synaptic vesicle fusion. The results suggest that the coupling of membrane curvature with membrane potential is of suffic...

John Gray M'Kendrick, physiologist (1841-1926).

IN 1859 The British Association met in Aberdeen. A letter' circulated in February of that year, asked for contributions to the Natural History exhibition suggesting that '. . . iftolerably complete (as a little exertion may easilymake it) will prove very interesting and instructive.' M'Kendrick was then an indentured clerk in a lawyers' office, and had assembled a marine aquarium in his lodging...
