The purpose of this study was to explore how individual differences—specifically abilities—were used in the construction of computer-mediated learning artifacts while working within a project-based learning environment. A case study design was used with five participants purposively selected from 61 eighth grade geography students at a small, private day school in the southeastern United States...

Donald Hebb postulated the existence of a mechanism of activity-dependent transcription and synaptic modification almost 60 years ago. While the details of this process are still unclear, a new study by Ince-Dunn et al. in this issue of Neuron indicates that NeuroD2, a calcium-regulated transcription factor, plays a central role in thalamocortical synaptic maturation.

ETAILED examinations of gene frequency changes at loci which show Dnon-Mendelian segregation are generally unavailable because realistic models are analytically intractable. Most naturally occurring examples of meiotic drive occur in only one sex. In at least one case, that of segregation distorter in Drosophila melanogaster (HARTL, HIRAIZUMI and CROW 1967), the sexes also differ in fecundity. ...
