  • 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. 

  • Telomeres

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

  • 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).

  • ERK1/2 signaling pathway

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

  • Courtship in Drosophila

    Various courtship songs produced by Drosophila species

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.

Mathematical models of organelle size control and scaling

Dr. Thomas Fai, Brandeis University
- | DRL 4C2 and via Zoom

Abstract: The size of the nucleus scales robustly with cell size so that the nuclear-to-cell size—the N/C ratio—is maintained during growth in many cell types. To address the fundamental…



From the Blackboard to the Clinic: combining mechanism-driven models with machine learning for personalized medicine

Dr. Giovanna Guidoboni
- | DRL 4E19 and via Zoom

Abstract: Machine Learning (ML) aims at extracting information and knowledge from data. ML is naturally interdisciplinary, as it bridges fundamental techniques of data analysis, typically…
