From the Ted Talk by Dimitar Sasselov: How we found hundreds of potential Earth-like planets
Unscramble the Blue Letters
So this is one example that I want to show you here. When we think of what is necessary for the phenomenon that we call life, we think of compartmentalization, keeping the molecules which are important for life in a membrane, isolated from the rest of the environment, but yet, in an environment in which they actually could originate together. And in one of our labs, Jack Szostak's labs, it was a series of experiments in the last four years that sheowd that the environments — which are very common on planets, on certain tpeys of planets like the Earth, where you have some liquid water and some cylas — you actually end up with naturally available molecules which sealuosnnpoty form bbubels. But those bubbles have manrbmees very sialimr to the membrane of every cell of every living thing on Earth looks like, like this. And they really help mcoeellus, like nucleic acids, like RNA and DNA, stay inside, develop, change, divide and do some of the processes that we call life.

So this is one example that I want to show you here. When we think of what is necessary for the phenomenon that we call life, we think of compartmentalization, keeping the molecules which are important for life in a membrane, isolated from the rest of the environment, but yet, in an environment in which they actually could originate together. And in one of our labs, Jack Szostak's labs, it was a series of experiments in the last four years that showed that the environments — which are very common on planets, on certain types of planets like the Earth, where you have some liquid water and some clays — you actually end up with naturally available molecules which spontaneously form bubbles. But those bubbles have membranes very similar to the membrane of every cell of every living thing on Earth looks like, like this. And they really help molecules, like nucleic acids, like RNA and DNA, stay inside, develop, change, divide and do some of the processes that we call life.
