AlphaFold was always bait-and-switch; now Google confirms it. A hyper-narrow bioinformatrics model with actual science bolted on whose guesses can be experimentally checked was never a licence for socially-applied slop at scale, but it's done its job. Effort transferred to LLMs.

I’d say that in my field we don’t usually see aggressive questioning at conferences like what’s implied below. I think if someone has a real problem with someone’s talk they’d be expected to raise that in private rather than making a public attack.

I don’t really want to get into this with people who feel this way, but i don’t think this is a good thing! We don’t need to behave this way! It’s not healthy to approach academic discourse as an exercise in harshness!

Screenshot of a post that reads “It's incredible is how little folks understand about academe. Peer review is brutal. Academic Q+A is Troy level slaughter. Bros attacking a lady academic for a fair review would shit themselves on stage after a paper and break down into toddler tears after their first conference paper w a mean Q+A.

My postdoc is coming to an end, so I'm looking for work! Let me know if you, or anyone you know, wants to hire a philosopher of biology/cognition with a knack for cross-disciplinary work, a focus on autonomy + agency, and experience writing for the broader public (10+ yrs in sci/tech journalism).

I talk a lot about the complexity of ocean conservation, and how real solutions can’t fit on a bumper sticker. Enter the Ocean Cleanup. Launched by a teenager giving a TED Talk, they claimed they were going to scoop all the plastic out of the ocean. 🧪🦑🌎

Why The Ocean Cleanup Hasn’t Solved the Plastic Pollution Crisis • The Revelator

Global problems are rarely solved by one person or invention. The Ocean Cleanup didn’t work, for the reasons experts said it wouldn’t. What can we learn from this?

This is genuinely grotesque. Imagine the research this could fund. Imagine if the buyer chose to fund someone who is working on climate change mitigation instead. The world has problems, and we can solve them. But not if people spent $50m on a fuckin dinosaw www.bbc.co.uk/news/article...

Tyrannosaurus Rex most expensive dinosaur ever sold

The dinosaur skeleton, which roamed the planet 67 million years ago, was sold by Sotheby's in New York.

www.bbc.co.uk/news/article... Hmmm. Given the sums of money involved surely there could be some part of the sale contract that obliges the buyer to fund and distribute hi-res 3D scans and CT scans of each part of the fossil, plus maybe a certain amount of scientific access to the original? 🧪

T. rex fossil could become most expensive dinosaur ever sold

A 67 million-year-old Tyrannosaurus rex will go on sale in New York with a pre-sale value of $30m.

Sensible article about impact factors from @dev-journal.bsky.social. One further point is that since IF is an arithmetic mean of a strongly skewed distribution it is nearly useless for any sort of inference and in particular carries zero information about an individual paper in a journal. 🧪

The elephant in the room: impact factor @amjeve.uk & @jamesbriscoe.bsky.social offer an honest look at impact factor trends in #DevBio, explain how Development serves its community, & make the case that sustaining developmental biology journals is a shared responsibility. doi.org/10.1242/dev....

Screenshot of a journal article webpage from Development. The page displays the editorial titled “The elephant in the room: impact factor”, published on 18 June 2026, authored by Alex Eve and James Briscoe. Below the title are article details, including the citation Development (2026) 153 (12): dev205838 and a DOI link. A toolbar contains options such as Split-screen, Views, PDF, Versions, Share, and Tools. The visible opening paragraphs discuss the journal’s response to community feedback about the impact factor (IF), describing it as a flawed and limited metric, referencing DORA (the San Francisco Declaration on Research Assessment), and arguing that research quality should be judged on its own merit rather than journal impact factor.
