Not-so-mutually beneficial coral symbiosis The partnership between corals and their intracellular algal symbionts has long been a textbook example of mutually beneficial association. In this essay, Mikhail Matz argues for an updated view in which the coral acts more as a farmer of algal cells to support its own growth.

I missed this when it came out last September - excellent essay!

I have an R56 that will pay for 1 year of a postdoc that will hopefully bridge us to a 4-year R01. It's not without risk but uh...everything in science feels like a major risk right now. We're in need of a #postdoc w/ #nmr experience. DM or email me for project details.

I am (optimistically) looking for a postdoc with solution state biomolecular NMR expertise to join our group. I can provide access to high-end instrumentation and technical assistance via our membership at the New York Structural Biology Center. #nmr #academicsky #postdoc
