Gamma‐secretases play a pivotal role in the generation of Aβ peptides. Mutations in these enzymes that cause early‐onset, autosomal dominant AD shift Aβ production towards generation of longer peptides. We have recently shown that the mutation‐induced shifts in the ratio of short‐to‐long Aβ peptides not only inform about mutation pathogenicity but...

Genomics is an increasingly important part of biology research. However, educating undergraduates in genomics is not yet a standard part of life sciences curricula. We believe this is, in part, due to a lack of standard concepts for the teaching of genomics. To address this deficit, the members of the Genomics Education Alliance created a set of ge...
