Our new experimental evolution study across 30+ locations using the plant Arabidopsis thaliana —— we direct "see" adaptation and extinction to different climates at the genetic as it happens! Read it in Science dx.doi.org/10.1126/scie... @ucberkeleyofficial.bsky.social @hhmi-science.bsky.social

Alright linguistics nerds, if we survive all this nonsense, and the bots keep improving, how does this change language evolution? More homogeneous or less? My intuition says it reduces pressure to conform, leading to more drifty and rapid changes at local scales. I’m probably very wrong though.

🧪This is important. Russel Vought fact check by @jenna-m-norton.bsky.social When a non-scientist says w/ certainty that NIH caused the Covid19 pandemic, it is a red flag & arrogance. His intention is to destroy science & implement Project 2025. Articles of impeachment have been drafted.

The beautiful preservstion of trilobite compound eyes will never cease to amaze me. On this little 400ish million year old Phacops you can see all the little lenses - each one a rigid calcite mineral crystal! Together they had excellent 360° vision, perfect for finding lunch on the seafloor.

I’m happy to share github.com/jpwares/mole... it’s got a long way to go but I felt a need to change my approach a few years ago. It’s clunky AF. I enjoy shaping it and keep useful stuff like your shiny apps there to help folks learn more experientially.

Been working off-and-on towards an .Rmd interactive textbook but haven't been able to work on for a while; need a Shiny tool in there that @silastittes.bsky.social wrote, and so I open it to 'cover image' - always struck by beauty of these #barnacles on rusty iron structures on the Florida coast.

Thought I would share this famous analogy from Felsentein’s book I just re-stumbled on. Just in case you’re bug in a box and missed it 😜

The last stages of finishing and submitting papers is folding laundry.

Angel, Clara (@ramencult.bsky.social), and Andy put together a really nice program for computing the various flavors McDonald-Kreitman tests and related analyses. Give it a spin! www.biorxiv.org/content/10.6...

Recently we're working with SNPs from whole genome assemblies to estimate ARGs. It's a pain to go from alignment files to vcf, keeping track of masked and invariant sites. So we wrote a snakemake/SLURM pipeline. Hope it's useful to others, and don't hesitate to post issues if there are problems!

It's a pretty funny criticism because 1) the data are sourced from a public database, NIH RePORTER 2) "Deranged activist" Jeremy Berg was an NIH institute director for 7 years and most importantly 3) Thacker admits the story is totally accurate

Apparently Jason Locasale and Paul Thacker have a problem with using publicly available data from NIH Reporter about the number of new and competitive renewal grants from fiscal year 2026 compared to previous fiscal years because I first posted it. 1/2

1. Kevin Gross and I have a new paper out today PLOS Biology. We used economic models based around screening games and the market for unpaid labor to highlight a meltdown cycle threatening peer review.

DHS is only now admitting that one of their agents shot and killed 23-year-old Ruben Ray Martinez, a U.S. citizen, last March. Another day, another DHS lie exposed. Congress must rein in this abusive, lawless agency.

What are you reading today evobio and popgen friends?

Can we simulate realistic evolutionary trajectories and “replay the tape of life”? In this work, we propose a flexible, generalizable deep learning framework for modeling how the entire protein sequence evolves over time while capturing complex interactions across sites. 1/n doi.org/10.64898/202...

The #fly community aims to achieve a comprehensive genomic study of the Drosophilidae family. @pankajd.bsky.social @bernardkim.bsky.social @petrovadmitri.bsky.social @darrenobbard.bsky.social present a comparative gene annotation for 301 #Drosophilidae species @plosbiology.org 🧪 plos.io/4c3pyrI

"One of the best takeaways those of us on the left or the center can hold is that tariffs, the annihilation of the safety net, aggressive tax cuts, and all of their other fiscal policies are not about enrichment as an end unto itself: they’re about impoverishment as a means to reinforce hierarchy."

If Moderna is no longer bringing vaccine trials for Epstein-Barr virus (good evidence that EB causes Multiple Sclerosis), herpes, and shingles because of Trump appointees, I want prison time for those appointees. This might be dooming millions to disease they don’t have to experience.

I am seeking a postdoc to join my group at UCLA -- ideally the candidate would have some experience in either population genetics or microbes/microbiome (computational background needed). We have a range of projects and are happy to tailer to your interests. Please dm/email me if interested.

A stunning detail the ICE chief shared in this hearing that was supposed to be a brag, except it isn't: ICE has arrested 379,000 people between Jan. 2025-Jan. 2026 -- but only 8,700 were suspected gang members or known suspected terrorists. That's 2%! www.huffpost.com/entry/latest...

Listen to this. Not a penny more for this. Abolish and prosecute anyone who had anything to do with it.

Definitely seeing the patterns of doomerism on here more. It’s sooooo useless and self-defeating to say nothing is working and there’s no hope — to the point where I wonder if any of the doomer accounts are commenting in good faith.

🚨BREAKING: Puerto Rico has been part of the United States since 1898, and people still act confused that Puerto Ricans are American. States that joined after Puerto Rico: • Oklahoma — 1907 • New Mexico — 1912 • Arizona — 1912 • Alaska — 1959 • Hawaii — 1959 Yet somehow this is still news to folks.

This is insane. The land used to produce crops to make biofuels could supply us with 22x as much power if you used solar farms. ourworldindata.org/biofuel-land...

Fun news! @gcbias.bsky.social and I are teaching a 2-week online population genetics workshop this summer to raise money for the Center for Population Biology at UC Davis. We're trying to gauge interest -- please fill this out if you might be interested! And please share broadly!

BREAKING: The Epstein survivors are releasing this ad on this Super Bowl Sunday to send the message that they will not “move on” from the largest sex trafficking scandal in the world. #standwithsurvivors

BREAKING: The Senate just blocked a bill that would have renewed ICE's budget without real, enforceable changes. This is a direct result of hundreds of thousands of people across the nation demanding that our Senators vote no.

This is what letting RFK jr go wild on health looks like

A retired Minneapolis couple who had guns pointed at them by ICE in a church parking lot. "They were obviously not trained at all. I've known many police officers in my life. These people were right off the streets." "They had the professional demeanor of criminals." ht: @paulgraham.bsky.social

Hey cuties. Everything sucks ass. Get some valentines and send them to your friends. I'm sad. You're sad. They're probably sad. Send them a valentine. It keeps Skype a Scientist running, which hey, is very good too. squidfacts.bigcartel.com/product/deep...

"You look around and think, 'Yep, this is it. Paramilitary deportations, apocalyptic foreign policy, and private corporations looting the federal government. This has to be the Fourth Reich.' Not so fast. It’s only the Fourth Reich if it comes from the Reich region of Germany."

While this is promising news, Liam and his father — like hundreds of other families — remain detained in Texas. No child or family belongs in ICE detention.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good. Stay free

We can't believe we have to say this, but POLIO IS REALLY BAD. RFK Jr.'s "independent" "expert" ACIP is destroying the foundations of our public health system. It cannot be clearer: if we want to save lives, we have to #RemoveRFKJr. Take action now: standupforscience.net/impeach-rfkjr

We profiled refugees who: Arrived in the country legally. Applied for green cards. Were arrested by ICE and detained. One refugee who was arrested found out they got their green card after being released. This is an unprecedented operation. www.nytimes.com/2026/01/26/u...

One small thing you can do *right now* — donate $5, $10, $50, whatever you're able — to this rent fund for South Minneapolis daycare workers whose families are sheltering in place. Can we raise $5k today?? Whatever you can give matters. And if you can't give, can you share? givebutter.com/Rbpl0z
