My look back at a year of claims about deextinction that didn't live up to the hype. No, the dire wolf is not back from the dead 🧪 Featuring @toriherridge.bsky.social @devoevomed.bsky.social @nicrawlencenz.bsky.social and @grenyer.bsky.social www.newscientist.com/article/2505...

De-extinction was big news in 2025 – but didn't live up to the hype
Biologists poured cold water on Colossal Biosciences’ claim to have brought the dire wolf back from extinction, and some worry the overblown headlines will undermine conservation work

“It’s like claiming to have brought Napoleon back from the dead by asking a short French man to wear his hat.” A short piece in The Conversation by me on why “de-extinction” is nothing of the sort, and bad, bad conservation. theconversation.com/why-de-extin...

Why ‘de-extinct’ dire wolves are a Trojan horse to hide humanity’s destruction of nature
Extinction is, for the time being, forever – and a symptom of our global economic system.

resjournals.onlinelibrary.wiley.com/doi/full/10.... New paper - England’s Biodiversity Net Gain policy could easily and inadvertently harm invertebrate populations because it doesn’t value habitats, condition, connectivity, or scale in ways that invertebrate populations respond positively to.

I’ll happily die on the hill of academic freedom of speech. But I’m damned if I’m sharing it with the Oxford Union who have absolutely nothing to do with it.

Just breaking my own Twitter embargo to congratulate @johnmittermeier and colleagues on refinding Otidiphaps insularis after 146 years, and also on outrunning pirates. We need to adjust the postgraduate research skills training accordingly :) www.bbc.co.uk/news/world-asia-63672…

The perfect time for the government to spend a zombie month while the Brexit ultras try a last power grab and we all pay. “…my lifeless two-year-old wasn't enough of an emergency to get the help of the ambulances. The cuts to the NHS are just so scary.” www.bbc.co.uk/news/uk-wales-633256...

I spent the summer off Twitter, pretty much. I’ve returned to it this week. And honestly, I think I need to fundamentally rethink whether and how I use it. I’ve curated my feed intensively, and professionally and politically it tells me a lot of things I want and need to know.

Amazing-looking paper in Nature on the new @IUCN ecosystem typology. It’s a hugely ambitious idea, with profound and quite hard-to-predict consequences for monitoring: www.nature.com/articles/s41586-022-… It’s also got an eye-opening (presumed) response to a reviewer…

Yes, a screenshot of a retweet. But the UN just retweeted to the world a warning from major conservation bodies about the Conservatives’ plan to destroy three fundamental legislative pillars of nature protection in the U.K. without clear replacement. It’s bad on a global scale.

I’m not particularly skilled at presentational politics, but I can’t help thinking that “Shall I publicly associate myself with pumping actual human shit onto beaches and rivers in August?” only has one answer, and it isn’t yes. inews.co.uk/news/politics/sewage-vo…...

A new strain of avian flu is decimating wild birds. Humans should worry on.ft.com/3QTFUWa “Good” summary article if you need one for non-technical types. I wish it was clearer on was the need for mitigating other threats, especially food supply, during recovery.

Is there a name for assorted digital cruft that builds up in your life but to which you are strangely attached? One of my accounts still gets promotional mails from a limo company I used once in NYC in 2004. I was even worried about them during lockdown.

An interesting read from Davos. Conflates two processes: an internally-consistent [sic] argument re ESG and profit-seeking (ie ROI horizon / discounting rate), and the ability of MAGA populism to feed off any power structure on.ft.com/3wVj0Gv

New paper out in @PLOSBiology from the lovely folks at GARD @ReptileMaps and collaborators. 🟩 We have some #XGBoost #ML magic, ~4500 DD #reptiles and simulated @IUCNRedList assessors (kind of!) 🟥 We find a lot of those DD species are probably in trouble. journals.plos.org/plosbiology/arti...

1.Nothing is worth normalising a legal silencing of academic discourse. The populists & the hydrocarbon industry would love it. 2.A reflection on positionality != a conflict of interest statement. It’s a heuristic for better research in many contexts and redundant in others.

I love thee to the depth and breadth and height my walrus can reach, when he wants to try. I love thee by the acres of his blubbery skin, I love thy tusks that show his strength within. I love thee for his blundering, slow-moving grace, the way he rolls in mud to hide his face.
