The ggpubfigs package just got more stable. Now, every time the code updates, it’s automatically tested on older, current, and development versions of Rβ€”which you can see on the green badge. I officially support R versions 4.4, 4.5, and the latest development release. (1/2)

Opinion | How a Conservative Texas District Rejected the Politics of Division Many Americans are growing both exhausted and frightened by Trump’s scorched-earth, hyperpartisan, fire-ready-aim approach to the presidency.

In @nytopinion.nytimes.com

β€œA lot of Americans are tired of being pitted against their neighbors and hunger to be brought together for a common purpose; they want common-sense solutions and to preserve our most cherished public institutions,” our columnist Thomas Friedman writes.

Thanks for this.
How does the affect the GWAS for diseases in which ~1% was explained? Do those diseases have also very low heritability? Or were the studies underpowered?

PhyloWeaver – Interactive phylogenetic tree editor Edit and visualize phylogenetic trees directly in your browser. PhyloWeaver lets you interactively rearrange tree topologies and export high-quality figures for publications and presentations.

I’ve released a tool to sketch and edit phylogenetic trees!
yawak.jp/PhyloWeaver/

Load a Newick file and intuitively add/remove/resize branches.
Useful for quick conceptual trees, extracting subtrees, or turning ideas into Newick.

I confirmed with the organizer of the Evomics workshops that we will be *unable* to extend the registration date.

Please ensure your seat and register before November 15 :)

Excited to share this work, out today in MBE! In polar fishes, we found that antifreeze protein genes expanded in copy number at low temperatures and contracted in the deep sea, highlighting a role of depth and pressure in AFP evolution.

When my out-of-office email hits your inbox and you have one set too, why doesn’t it result in an infinite out-of-office emailing loop?

Grant writers of the NIH kind:
Did you know the grant guide asks for Letters of Support from *all* senior personnel, Co-Is, etc...?
I have never done this! Have you? I had no idea, just assumed they're funded on the grant and helped write it, so why?

Reupping support for journalism outlets not beholden to corporate interests. When everything is a commodity, it's worth asking where your news is coming from.

Congrats to lab postdoc, Dr. Emily Kopania, on being selected for a Catalyst Award from the Center for Evolutionary Biology and Medicine! Her project will develop a Virtual Reality experience demonstrating to students how other species see the world through their differing visual systems.
