It’s often said that we know more about space than we do about Earth’s own oceans. In the case of the midocean ridges, the maxim is pretty much true.
In the biological world, we see that many things come in different shapes and sizes: animals, plants, microbes, and proteins. It turns out that even RNA falls into that category. In this article, we will explore what circular RNAs are, the history of their discovery, and why we should care about them.
Before there were chickens or eggs, there were RNA molecules that gained the ability to duplicate themselves. How did these molecules manage to do this outside of cells on the early earth, and how did this lead to life as we know it?
You probably remember the 1993 film, Jurassic Park. If not, the skinny is that a bunch of ambitious scientists use dinosaur DNA from preserved mosquitoes combined with modern reptile DNA to create your family fun dinosaur theme park (with real-life dinosaurs). It turns out this work of science fiction is a little more science and a little less fiction these days. I am not actually talking dinosaurs here, but we are now in an era where de-extinction is becoming possible. Before anyone goes all, honey, grab the flares, just STOP, collaborate and listen.
