A good understanding of the epidemic’s dynamic’s mechanism is needed in order to anticipate and predict the range of pandemic phenomena. To do this, different models exist from the simplest to the hardest, each taking into account different parameters.
In the case of Covid-19, models suffer from the presence of superspreaders, people who are responsible for the main part of infection.
In this video, the issue posed by superspreaders will be explained at the same time as the different models we can use to predict their impact on the dynamics of the epidemic.
Watch Hadrien's video to learn more about how simplest epidemiological models work.

![Designing a self-propelled vesicle inspired by a bacterial swimmer
We present an original design for a self-propelling lipid bilayer vesicle using a DNA origami rotary motor, powered by transmembrane water flow[1] generated via photoactivable sodium pumps[2] and mimicking bacterial locomotion with a rigid helical flagella.
We have built a numerical model to assess the compatibility between the elements of the system and the viability of its structure and function. From this model, we have identified the limitations of the current design and proposed additional functions to consider for future development.
