Great read, one small correction - pretty sure it's Dan's wife Marian who was nicknamed "Bunny" not Dan Koshland...

Do we need a go-fund-me for a Claude Code Max subscription for @jeremymberg.bsky.social to unlock even more valuable reports?

GitHub - GrotjahnLab/surface_morphometrics: Morphometrics for Membrane Surfaces Segmented from Cryo-ET or other volumetric imaging. Morphometrics for Membrane Surfaces Segmented from Cryo-ET or other volumetric imaging. - GrotjahnLab/surface_morphometrics

I've been working on Surface Morphometrics for a new version (coming soon), and made some significant (AI-assisted) performance improvements, especially in pycurv (20-50x!). If you've had technical issues or just felt like it was too slow, give it another try! #teamtomo github.com/GrotjahnLab/...

AI is not a peer, so it can’t do peer review If we still believe thatΒ science is a vocationΒ grounded in argument, curiosity and care, we can’t delegate judgement to machines, saysΒ Akhil Bhardwaj

'to treat peer review as a throughput problem is to misunderstand what is at stake. Review is not simply a production stage in the research pipeline; it is one of the few remaining spaces where the scientific community talks to itself.' 1/3

On the plus side - hallucination is dramatically lower now than a year ago. In the downside- peer review should be fun an a mental exercise (two things you should never outsource to AI)

As soon as NIH decided that preprints were A-OK we started preprinting everything.

The biggest negative is that now once we've preprinted I lose interest in the actual peer-reviewed article. Which for me isn't a big deal (I'm tenured) but my folk aren't. So I need to force myself to keep up on it

This is cool - is it: app.benchmate.ai/pricing or something you are writing?

Happy new year #teamtomo! We've resumed our OHSU tomo journal club, and this year I am going to be sharing it on bluesky. This week we did a roundtable, where attendees each brought a paper and did a 3-5 minute discussion of what they thought was cool about it. Here are the papers they discussed!

Me too. Just trying to brainstorm ideas that might incentivize more retirement without a forcing function of a hard cutoff

Sorry. I misread! Many reacting strongly the other way - they should just be forced to retire at age X.

I think the trouble is that people are still competitive- and don’t have an off-ramp for their identity as a scientist. I’m with you, I’ll exit stage right when the time comes. But I see many who don’t….

from: hhmicdn.blob.core.windows.net/policies/Inv... "expanded phase out" of 5 years, rather than going through competitive renewal (7 years if successful and 2 years if not)

A point in favour of this: an off ramp exists for HHMI investigators and many actually take it

07.01.2026 19:29 πŸ‘ 4 πŸ” 1 πŸ’¬ 1 πŸ“Œ 1

I agree it’s hard. Much like convincing them to retire. But the alternative isn’t retiring. It’s renewing their R01.

07.01.2026 19:23 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

People just don’t do it though. I think an off-ramp program would allow people to hold their heads high, maintain identity as a scientist ,etc.

Trying to brainstorm policy ways to get people to do actually do it.

07.01.2026 19:20 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

Great. I don’t think advocating for either or both of these are mutually exclusive. Need many policy ideas for this problem…

Yes. We have such programs but - How do you get them to transition out to free up resources? Hence the reverse K99 as a potential off ramp policy…

The problem is people don’t retire. What’s a policy solution to help?

07.01.2026 18:55 πŸ‘ 3 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

I also do- but I’ll tell you there aren’t really any levers of incentives to get people to do that

07.01.2026 18:55 πŸ‘ 1 πŸ” 0 πŸ’¬ 1 πŸ“Œ 0

The alternative isn’t no money. It’s 4-5 years of them renewing.
