Newton International Fellowships | Royal Society This fellowship is for non-UK scientists who are at an early stage of their research career and wish to conduct research in the UK.

If you're a non-UK scientist who wants to come to the UK for a postdoc, this year's Newton Fellowships are now open. You'll need a lab to host you (which could be me, but truly, could be any PI, so get in touch with someone you'd like to work with!)

I'm excited to be able to share this analysis of rubella transmission in Nigeria that was developed with NCDC and USCDC thanks to an enormous effort by both to do a HUGE national-scale sero-survey using archived sera from 2018.

Can anyone put me in the direction of a paper that synthesizes microbiome diversity across systems? Do we have any idea how variable the number of taxa in microbiomes is? I feel like I have seen this graph in a presentation but I’m not sure if there’s a publication looking at this. οΏΌThanks!!!!
