What do you think about our new preprint? 🥳🥳🥳Please let us know! It’s about how geography, mode of transmission, and long-term host–parasite coevolution is shaping genomic variation in a microsporidium. @peterdfields biorxiv.org/content/10.110…
Great conference during the last two days: In person and with free coffee. I got to present a poster about my PhD project. Check it out online: doi.org/10.6084/m9.fig… Work with @peterdfields and Dieter Ebert (in prep.) #biology22basel @Biology22Basel (1/3)
Evolutionary Biology Field Course, Guarda, Switzerland, summer 2022. Dieter Ebert is reviving this after a 2 y hiatus. John Krebs and @hopihoekstra on the faculty! Details: evolution.unibas.ch/teaching/guard…

There is now enough genomic data from the US and Germany to repeat this approach to estimating Omicron-specific rate of epidemic spread. Here, we observe similar initial rapid spread in the US and Germany. 1/10
We've seen exceptionally rapid spread of Omicron in South Africa. Although we should expect this rapid spread to follow in other geographies, we've mostly lacked data to confirm this until recently. 1/21

We've seen exceptionally rapid spread of Omicron in South Africa. Although we should expect this rapid spread to follow in other geographies, we've mostly lacked data to confirm this until recently. 1/21
As the Omicron epidemic continues to expand in South Africa and as case counts and sequencing data continues to come in, we can better estimate the current transmission rate of Omicron. 1/19
Following up here with speculative estimates of the rate of spread of Omicron and a stab at how to apportion this rapid rate of spread between intrinsic transmissibility and immune escape. 1/18
Just started: a discussion among virologists and evolutionary biology experts on the new Omicron variant, looking at data in the early days.
I think there's perhaps been some confusion regarding transmissibility vs immune escape in Omicron. The apparent rapid increase in frequency of Omicron in Gauteng does not mean that Omicron is necessarily more intrinsically transmissible than Delta. 1/15
There have been a number of overview threads on the emerging variant designated as @PangoNetwork lineage B.1.1.529, @nextstrain clade 21K and @WHO Variant of Concern Omicron. I'm not going to attempt to be comprehensive here, but will highlight a few aspects of the data. 1/16
Here's how mutations in #SARSCoV2 Nu variant (B.1.1.529) will affect polyclonal and monoclonal antibodies targeting RBD. These assessments based on deep-mutational scanning experiments; underlying data can be explored interactively at jbloomlab.github.io/SARS2_RBD_Ab_e… (1/n)
Hi Twitter. I just submitted my first manuscript to biorxiv with @peterdfields. Check it out: doi.org/10.1101/2021.1… 🥳

I wrote an R script to download photos from #inaturalist based on a list of species. Maybe it can be useful for someone else? Code is available at github.com/ghuertaramos/I…
