We’ve been heads down @ArcadiaScience for a bit but the @arenabioworks news this week caused me to dump thoughts. hard things are hard; don’t be such a fucking hater. Reflections on parallels w our own institutional experiment here seemay.substack.com/p/big-experi...

this is most of all true for the actual trainees. protecting them can inadvertently block them from opportunities they want. don't be that guy

overall, way fewer people are arguing against our policy as change seems inevitable now

A note in here for other science philanthropists… we have a chance rn to help scientists rethink systems, technical & operational. They’re game to take useful risks, let’s help them. Coming soon: more open science research, experimenting outside journals… seemay.substack.com/p/from-syste...

It will certainly be important to include more modalities (and scientists) beyond X-ray, which we hope to do in the future! Lots of fun work to be done to ensure interoperability in that way

Announcing the Diffuse Project! We're unlocking protein dynamics through diffuse X-ray scattering - the overlooked signal that could revolutionize how we understand protein motion. seemay.substack.com/p/from-syste...

Doing this will require co-iterating across an entire data system, not just refining one part. And we're experimenting with how to share all of this (our real-time thinking, pivots, tools, data) openly and quickly all outside of traditional journals
110
Seemay Chou @seemaychou.bsky.social · 12/08/2025
Tldr, we're focusing on diffuse scattering, which is the messier background signal in X-ray diffraction images. These data are often tossed because they're complex, but this complexity is where so much of the interesting biology sits
130
Seemay Chou @seemaychou.bsky.social · 12/08/2025
Our take: more of the same data won't get us there. We're bringing together top experts across almost every node of the X-ray pipeline to generate the right kind of data to model ensembles of different protein conformations. Think: pictures to movies

We're dreaming about the next frontier in structural biology: protein motion. Understanding how proteins move will be the next big unlock for predicting function

Hoped others would jump on it, but wasn't super straightforward so we ran with some predictions ourselves. Ultimately collaborating with sea squirt and choano experts to scope some pilots (biggest filter was finding people willing to publish openly/rapidly but we prevailed!)

Props to those taking the first steps. Those first steps are scary, messy, and the only guarantees I can offer is that now we have a chance at something better. More announcements in coming months.

Seemay Chou @seemaychou.bsky.social · 05/06/2025
In the last 48h since announcing our policy, 4 academic PIs decided that they can indeed take this risk w us. They aren't the glam journal "elite" but they're damn good scientists. They're on the more junior side, and that's fucking awesome because they're our future.

Seemay Chou @seemaychou.bsky.social · 05/06/2025
#2 is actually a made-up concern in at least 50% of the cases that I help people work through. When you start talking to the real people involved, students are often hungry to try a different way but don't think their PIs will "let" them.

Seemay Chou @seemaychou.bsky.social · 05/06/2025
#1 makes sense because they actually think they have the most to lose since their success was built on the existing system. Why would they give up a winning hand even if it's in a broken game?
110
Seemay Chou @seemaychou.bsky.social · 05/06/2025
The "elite" scientists who publish in glam journals are actually waiting for the rest of you. When I talk to them, they either say: 1) Happy to do it once others do, and/or, 2) I can't do it because I have to protect so many trainees.

Seemay Chou @seemaychou.bsky.social · 05/06/2025
A v common suggestion I get re: publishing work outside journals is "if you just get some elite scientists to do it, everyone else will do it." This is an instinct that may seem sound, but here's what I've found irl:

I know this is a hard conversation to have, but it's really important that scientists lead it. Particularly at this moment. We might be able to really change things for the better, especially with all the technologies at our fingertips today.

We want to hear from actual scientists about what the bottlenecks and specific opportunities are. As a microbiologist myself, I'm eager for this conversation and am invested in seeing it happen... by literally investing $ into it. Please help us do this in the right way.

Seemay Chou @seemaychou.bsky.social · 23/01/2025
This is going to be hard. Most functions are v complex. I don't think many are thinking realistically about how we predict causal basis without breaking the bank. Datasets need to public/structured, tools need to be open/maintained, problems need to be more defined beyond "bio foundation model."

Seemay Chou @seemaychou.bsky.social · 23/01/2025
And not just for microbes, as a window into eukaryotes too. Microbes not only have features that are conserved across the tree of life but also have honed extraordinary tools for studying other organisms they infect. We've learned a ton about basic cell biology from our microbial friends.

Picking the right research organisms/models in a data-driven way is a huge problem that will require all of us to fix -- no one denies this is a problem, no matter who you talk to (academia, pharma, etc). Yet we pour BILLIONS each year into clinical trials based on faulty animal models.

Another way to structure data is thru lens of evolution. People forget this was a key unlock for protein predictions (MSAs). There's not enough data/compute/$ for big AI promises without. Why I've devoted all my energy to old school, open evo tools @arcadiascience.com -- that's "big bio" IMO
