  • Telomeres

    Giant ‘polytene’ chromosomes (white) from a fruit fly with a fluorescent probe (red) that hybridizes to a telomere-restricted DNA repeat.

  • Sea Anemone

  • Porphyrogenes peterwegii

     Pupa of the butterfly Porphyrogenes peterwegii "peering" out of its leafy nest with false eyes, which in turn mimic the eyes of a snake, thereby protecting the pupa from small feather-brained  birds.

  • 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).

Biology is fundamental to our changing world. The 21st century challenge for our students, our scholars, and the greater society is to understand our place in this changing world and to create fundamental knowledge for informed policies, economies, and social structure.
