Benny Chain: The T cell receptor repertoire in health and disease

Mon, Mar 25, 2019, 12:00 pm

The human adaptive immune system makes robust decisions which regulate quantitative and qualitative parameters of a complex physiological system, to prevent invasion and destruction of tissues by the enormous array of microorganisms which share our environment. Remarkably, these decisions are made by a distributed system made up of moving parts...

Elizabeth Hillman: High-speed imaging of real-time brain activity

Mon, Apr 1, 2019, 12:00 pm

Optical reporters of neural activity have improved dramatically over the past decade. Recent developments in optical imaging approaches have unlocked the power of these indicators and can now provide real-time read-outs from large populations of brain cells in a wide range of living organisms.

Massimo Vergassola: Waves and flows in the early embryogenesis of Drosophila melanogaster

Mon, Apr 8, 2019, 12:00 pm

Early embryogenesis of most metazoans is characterized by rapid and synchronous cleavage divisions. After fertilization, Drosophila embryos undergo 13 swift rounds of DNA replication and mitosis without cytokinesis, resulting in a multinucleated syncytium containing about 6,000 nuclei.

Markus Meister: Large Ratios in Brain Science

Mon, Apr 15, 2019, 12:00 pm

In physics and engineering dimensionless numbers frequently help to characterize the state of a system. I will present a series of vignettes about unusually large dimensionless numbers that arise in brain science. These can indicate issues that are poorly understood, and in some cases clearly misunderstood.
