Please explain!

Please explain!

By Helena and Anaëlle
We are Anaëlle and Helena, third year Microbiology Phd students at the University of Copenhagen. To distract ourselves from the dauntingly fast approaching deadline, we decided to produce a podcast series called “Please explain!”, where we talk about different science topics in an easily digestable way.
