This Friday from noon to 1 pm PST, we'll discuss this paper about major transitions in the history of life on Earth.
I am also attaching next week's paper: Summons et al.'s report on managing contamination on the Mars 2020 rover. It's a long report, so just pick and read the section of your choice. Here it is a week in advance, so you have more time in case you're interested in browsing the paper further.
