My company owes €21 in tax, but I can't figure out the correct way to pay it. The tax authority charges 0.1% interest per month that I am late, so in 632 years I'll be bankrupt. 😒

Announcing #ASHG2026 At a Glance! barrettlab.eu/ashg2026

We are recruiting a postdoc in computational genomics for predictive medicine! 📢 This is a great opportunity to be one of the first members of a newly established lab led by Prof. @jeffbarrett.eu, who has over 20 years’ experience leading genomics research teams. 🔗 jobs.helsinki.fi/job/Helsinki...

I think we are probably at a peak time for AI generated software, where there are extensive human-generated frameworks and libraries with documentation and example code for the LLMs to be trained on. With knowledge and experience it can create great tools but I am not sure how long this will last.

Go ahead, reader, make someone's day go.nature.com/4zvu7ng

For Colombian Exchange Day, I am drinking a mocha, a food that no one before 1492 could have tasted.

This Black Bear is the Queen of PA. All summer long she's been spotted roadside feeding with her three cubs. This week we met her alone, nonchalantly wandering through the last waking weeks of autumn. #mammals #SK

Good thread on today's dump by OpenAI of 722(!) preprints on unsolved math problems. Slightly alleviated my sense of existential despair about being a scientist. Slightly.

Damnit, I almost got a good hallucination

My feed is divided.

Celebrating korvapuustipäivä in style. 🇫🇮

It’s Korvapuustipäivä in Finland and Kanelsbullens Dag in Sweden, which is to say Cinnamon Bun Day! I happen to have a recipe for Swedish Cinnamon Buns, so of course it has to be #RecipeOfTheDay www.nigella.com/recipes/swed...

This essay (from 1990) is still the most useful piece I've ever read on how to write about science clearly. The "old-first, new-last" thing is the most important bit. www.americanscientist.org/blog/the-lon...

Excited to share our new preprint "A cross-tissue splicing signature as a quantitative biomarker for ReNU syndrome" tinyurl.com/RENUsig Led by super⭐ duo @ruebenadawes.bsky.social @alexblakes.bsky.social We show that just 6 alternative 5'splice site events perfectly predict ReNU syndrome 🧬 🧵 1/4

Read a bit of @emilyrcwilson.bsky.social’s Odyssey to my 8-year old tonight (book 10, Aeolus and Circe are more exciting than the suitors). And, WOW, is this meant to be read aloud. The verse just cooks in a way you can’t replicate inside your head.

I like to keep Claude on its toes by mixing wildly different topics in the same chat. For example, this reply came in a chat titled, "Montreal steakhouses": "The mixing parameter α is worth tuning jointly with λ, though results are often fairly flat across α in a moderate range like 0.3 to 0.7."

Are there key discoveries made with spatial RNA seq? Or what are your favorite spatial rna seq papers? Pls reski!

I wonder if worker agents complain about their supervisor agents behind their backs. Do they have agent development discussions about their career prospects?

Meet @jeffbarrett.eu, new Professor of Computational Predictive Medicine @helsinki.fi & @ellisinstitute.fi! Barrett's career spans genomics, public health and industry. His research focuses on using AI to analyse large-scale health data to discover new biomarkers. 🔗 www.helsinki.fi/en/news/publ...

I'm in love.

First opportunity to join my new lab! Deadline is in <1 week, but applying only needs a CV and cover letter. (See previous tweet for advice on how (not) to write the cover letter) www.ellisinstitute.fi/postdoc-and-...

Tempted to use AI to write your cover letter or email to a potential employer? RESIST! It is simultaneously obvious, insulting, and renders you totally undifferentiated from the other 80 people being considered t the same time. There has never been a better time to write concisely in your own voice!

The PROFILE trial of top-down infliximab in Crohn's disease has reported dramatic results over 5 years of follow up. My thoughts here: barrettlab.eu/blog/profile/ www.sciencedirect.com/science/arti...

Both stories are just perfect.

WTF is wrong with Slack that by default they opt you into an email summary of unread messages of every workspace you join.

Without saying your age, what is your favorite movie that came out when you were 20 years old?

"we find minimal spousal assortment for personality in recent history" 🤣

This mix has absolutely carried me through a month of grant writing. Caught in Joy is generally awesome, but I have felt the need for the extra kick of this playlist compared some of his more chill examples. cc @michelnivard.bsky.social youtu.be/azH0gSbQ73g?...

I have heard of Piker and Alix Earle, but have not to my knowledge seen any of their content. The other 23 are tabula rasa. 💪

Here is a link to slides I will present today at Options XIII Conference for Control of Influenza meeting: slides.com/jbloom/optio... Slides describe using sequencing-based neutralization assays to characterize human neutralizing antibody landscape to seasonal influenza virus in near real time

Looks like it was Lowell Weiss: clinton.presidentiallibraries.us/items/show/4...

"In fact, it is now conceivable that our children's children will know the term cancer only as a constellation of stars." Bill Clinton's speechwriter (announcing completion of the human genome project) was pretty good. Anybody know who it was?

I think my favorite part of this is Grover Cleveland as near-great.

$3.7 billion spent on APCs in 2025. That's ~1000X more than it costs to run bioRxiv/medRxiv. Worth thinking about as we consider how to fund infrastructure... arxiv.org/pdf/2608.16322

i’m dying. i’m dead

Spot on. Writing a paper does two things: 1. shares your work with the world; 2. helps you think more clearly about your work. Using AI to write wipes out (2). See also: using a forklift at the gym www.schneier.com/blog/archive...

This is a real bummer.
