How did life first appear on Earth? Are there living organisms beyond Earth? Scientists, throughout time, have tried to understand what could be considered as life and how the building blocks of living organisms could have emerged in early Earth conditions. This video aims to show the main steps of the origins-of-life study and also discusses the definition of life in order to know what we should consider alive.

![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.
