Molecular paleoecology is the application of molecular data to test hypotheses made by paleoecological scenarios. Here, we use gene regulatory analysis to test between two competing paleoecological scenarios put forth to explain the evolution of complex life cycles. The first posits that early bilaterians were holobenthic, and the evolution of macrophagous(More)
The sea urchin embryo is a classical model system for studying the role of the cytoskeleton in such events as fertilization, mitosis, cleavage, cell migration and gastrulation. We have conducted an analysis of gene models derived from the Strongylocentrotus purpuratus genome assembly and have gathered strong evidence for the existence of multiple gene(More)
KAP is the non-motor subunit of the heteromeric plus-end directed microtubule (MT) motor protein kinesin-II essential for normal cilia formation. Studies in Chlamydomonas have demonstrated that kinesin-II drives the anterograde intraflagellar transport (IFT) of protein complexes along ciliary axonemes. We used a green fluorescent protein (GFP) chimera of(More)
Two experiments compare pe~orlnance on a prototype indicator of perceptual defencelvtgilance with performance on other related measures of individual differences. On the basis of theoretical expectations and empirical findings, participants’ performance on the prototype indicator of perceptual defencelvigilance was predicted to relate to the personality(More)
A relatively small number of signaling pathways govern the early patterning processes of metazoan development. The architectural changes over time to these signaling pathways offer unique insights into their evolution. In the case of Hedgehog (Hh) signaling, two very divergent mechanisms of pathway transduction have evolved. In vertebrates, signaling relies(More)
Research into mind-matter interactions (MMI) investigates the possibility of some sort of relationship between the consciousness of living beings and external material systems, mediated by mechanisms beyond those we presently understand. This paper presents a conceptual basis for experimental strategies in the investigation of such effects. Twelve different(More)
centrosome's job as an MTOC. One view was that the the " mysterious " centrosome has been demystified by centriole was just along for the ride, possibly en route real progress. A molecular basis for many centrosome for a task in meiosis. However, the tide may be turning functions is rapidly emerging. To the detriment of poetic against the centriole(More)
Computational methods of inferring regions of noncoding DNA that regulate gene activity are important to efficient biological validation of gene regulatory control. In many cases the available resources may allow for relatively few biological assays to be performed, and computational results allow these assays to be tightly focused on the highest confidence(More)
