A maggot becomes a fly

Each living animal or human originates from a single cell, which divides several times, then cells differentiate and robustly self-organize into tissues and organs. This talk will discuss mechanisms governing such tissue development, which involve a complex regulation based on genetics, but also on physics. In fact, forces, shapes, movements, shape changes, all obey the laws of mechanics. As an example, we will introduce the Drosophila metamorphosis: the fly strikingly changes, within a few days, from a rather simple maggot shape to a refined adult shape with wings, legs, antennas, waist, neck, and compound eyes.

The Colloquium Ehrenfestii takes place Wednesday evenings starting at 19:30 hours in the main auditorium of the Oort building. Before the Colloquium, there is a common dinner in the canteen located on the ground floor of the Oort building. This dinner starts at 18:00 hours sharp and is free of charge, under the condition that one attends the colloquium and that one has made a reservation before noon on the Tuesday preceding the colloquium.

Recent colloquia have been recorded.

Meal registrations may close earlier, when 80 persons have signed up.
