An epithelial signalling centre in sharks supports homology of tooth morphogenesis in vertebrates Alexandre P Thiery, Ariane S Standing, Rory L Cooper, Gareth J Fraser ABSTRACT: Development of tooth shape is regulated by the enamel knot signalling centre, at least in mammals. Fgf signalling regulates differential proliferation between the enamel knot and adjacent dental epithelia

Evaluating the Shark Deterrent Effects of the Novel Exclusion Barrier in Comparison to the Rigorously Tested Sharksafe Barrier Technology

Evaluating the Shark Deterrent Effects of the Novel Exclusion Barrier in Comparison to the Rigorously Tested Sharksafe Barrier Technology Craig P O’Connell, Julia Crews, Andre King, Juliet Gressle ABSTRACT: Although exceedingly rare, shark attacks have a disproportionately large impact on human behavior, often resulting in shark culls. Due to the invasive nature of shark culls,
