  • Arabidopsis

    Wild-type and transgenic Arabidopsis plants expressing miR156, a microRNA that promotes juvenility and increases the rate of leaf initiation

  • 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.  

  • Telomeres

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

  • Sea Anemone

  • Bacterial Respiratory Complex

    Structural model of a bacterial respiratory complex III: remember that when you respire, your complex III perspires to produce your body's energy.

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.

Exploring Evolutionary Novelty in Human-Altered Landscapes: Mechanisms of Survival and Persistence Under Global Change

Dr. Anthony Snead
- | Leidy 109 and Zoom

Abstract: As anthropogenic activities continue and intensify, biological systems are increasingly exposed to rapidly changing, non-analogous environmental…



From modular organisms to biological machines: the plasticity of life

Dr. Douglas Blackiston, Harvard University
- | Fagin 116 and Zoom

Abstract: Living organisms remain more adaptive, robust, and regenerative than any artificial system yet developed.  It is thus promising that engineering has seen a surge in novel building…
