Further evidence in support of a new amyloid-independent hypothesis for the pathogenesis of Alzheimer's disease is provided, with an expanded set of Alzheimer-causing mutations in the protease that produces amyloid.

Transport of double-stranded RNA from parental circulation to progeny using the transmembrane protein SID-1 can occur through multiple routes during C. elegans development and buffer heritable changes in gene expression.

A new collection of driver lines enables experimental manipulation of over 300 cell types centered around the mushroom body in Drosophila.

The composition of nodes that effectively transmit sinusoidal waves in a model network resembling C. elegans' electrical synapses network changes according to the waves' wavenumber.

Laminin gamma1-dependent basement membranes are required for multiple aspects of olfactory system development in zebrafish, including the maintenance of placode tissue shape and the growth of the olfactory axons.
