  • ERK1/2 signaling pathway

     ERK1/2 signaling pathway regulates exocytosis and tumor invasion through phosphorylation of the exocyst complex. 

  • Drosophila

    Drosophila are small flies, typically pale yellow to reddish brown to black, with red eyes. Many species, including the noted Hawaiian picture-wings, have distinct black patterns on the wings. The plumose (feathery) arista, bristling of the head and thorax, and wing venation are characters used to diagnose the family.

  • Archaea

    Haloferax volcanii motility mutants stab-inoculated on a 0.3% agar motility plate. The “halos” and “rings” likely reflect the motility of this archaeon following gradients of attractant or repellent chemicals. 

  • Larix siberica

    Siberian Larch, taken at our field site near Lake Khovsgol in north-central Mongolia.  We are analyzing tree-ring width and stable isotopes of the tree rings to reconstruct climate, and Larch responses to climate change, over the past century as the temperature in Mongolia has risen.  

  • Malaria parasites

    Malaria parasites (and their kin) can be viewed as minimal eukaryotes, harboring a nucleus (yellow), a secretory pathway the Golgi (purple) and specialized ‘rhotpry’ organelle (black), and two endosymbiotic organelles, the mitochondrion (red) and apicoplast (green).
