Nationwide Soil Microbiome Mapping Project Connects Students and Scientists - Eos Researchers and students are building a comprehensive picture of the microbial life beneath our feet.

β€œSoil is one of the last frontiers on Earth,” says @avahoffman.com. A new project aims to map it.

Hey are you looking for a postdoc focusing on microbial
ecology/bioinformatics? Hit me up - it’s not my lab but trying to help someone else staff their lab. If you have a student about to defend, this could be a great chance to get a ton of papers.

How about we start with societal stigma around life-saving mental health treatments

"Women are PIs on 58% of the canceled grants, although they are PIs on only 34% of all active NSF grants.

Similarly, Blacks are PIs on 17% of the terminated grants, although they make only 4% of the total pool. Hispanic PIs and those with disabilities were twice as likely to lose a grant."

I served on an NIH panel earlier this year. All told, I spent almost an entire work week (38.25 hours) outside my normal work training, writing critiques, and participating in the panel. W/ the stipend, I made $5.23/hr. There's a lot of unpaid labor in science, but this one feels especially icky.
