Very proud to have launched our manifesto and report to make Dutch academia more sustainable - a moment to celebrate after two years of hard work with the Green Young Academy, DJA and many inspiring colleagues

Harvard Gazette: Gazette: “You are the mother of two In ten years you have produced three novels and two short-story collections. Can you talk about your process and how you manage work and family?” Groff: “I understand that this is a question of vital importance to a lot of people, particularly to other mothers who are artists trying to get their work done, and know that I feel for everyone in the struggle. But until I see a male writer asked that question, I am going to respectfully decline to answer it.”

Years ago I started the Green Young Academy with @sanlifaez.bsky.social & @anne-urai.bsky.social. Across meetings, zoom calls, pitches and even a meeting with the King, this grew into 2 projects launched today: A report on Universities' sustainability plans & a manifesto with sustainability pledges

I have a vivid but possibly made up memory of paper(s) showing that dual task interference is greater if the same task is done under high time constraints vs low/no time constraints. Any pointers come to mind?

Gather round, all those bayes curious, pragmatic, committed or indifferent, for an elegant and flexible way to approach reliability estimation using bayesian measurement models! All thoughts and ideas welcome

New preprint with @rogierk.bsky.social @paulbuerkner.com - we introduce "relative measurement uncertainty" - a reliability estimation method that's applicable across a broad class of Bayesian measurement models (e.g., generative-, computational- and item response theory-models osf.io/h54k8

Choosing to go by train/ferry to #Flux2025 I emitted SEVEN times less C02 compared to a plane trip.

Air travel is one of the largest contributors to the carbon footprint of research. Researchers, universities and conferences have the responsabilities to create more sustainable alternatives.

Finally! 🤩 Our position piece: Against the Uncritical Adoption of 'AI' Technologies in Academia:
doi.org/10.5281/zeno...

We unpick the tech industry’s marketing, hype, & harm; and we argue for safeguarding higher education, critical
thinking, expertise, academic freedom, & scientific integrity.
1/n
Abstract: Under the banner of progress, products have been uncritically adopted or even imposed on users — in past centuries with tobacco and combustion engines, and in the 21st with social media. For these collective blunders, we now regret our involvement or apathy as scientists, and society struggles to put the genie back in the bottle. Currently, we are similarly entangled with artificial intelligence (AI) technology. For example, software updates are rolled out seamlessly and non-consensually, Microsoft Office is bundled with chatbots, and we, our students, and our employers have had no say, as it is not considered a valid position to reject AI technologies in our teaching and research. This is why in June 2025, we co-authored an Open Letter calling on our employers to reverse and rethink their stance on uncritically adopting AI technologies. In this position piece, we expound on why universities must take their role seriously toa) counter the technology industry’s marketing, hype, and harm; and to b) safeguard higher education, critical thinking, expertise, academic freedom, and scientific integrity. We include pointers to relevant work to further inform our colleagues. Figure 1. A cartoon set theoretic view on various terms (see Table 1) used when discussing the superset AI (black outline, hatched background): LLMs are in orange; ANNs are in magenta; generative models are in blue; and finally, chatbots are in green. Where these intersect, the colours reflect that, e.g. generative adversarial network (GAN) and Boltzmann machine (BM) models are in the purple subset because they are both generative and ANNs. In the case of proprietary closed source models, e.g. OpenAI’s ChatGPT and Apple’s Siri, we cannot verify their implementation and so academics can only make educated guesses (cf. Dingemanse 2025). Undefined terms used above: BERT (Devlin et al. 2019); AlexNet (Krizhevsky et al. 2017); A.L.I.C.E. (Wallace 2009); ELIZA (Weizenbaum 1966); Jabberwacky (Twist 2003); linear discriminant analysis (LDA); quadratic discriminant analysis (QDA). Table 1. Below some of the typical terminological disarray is untangled. Importantly, none of these terms are orthogonal nor do they exclusively pick out the types of products we may wish to critique or proscribe.

“a deliberate, systematic starvation of an entire population”

A statement by Doctors Against Genocide.

#Gaza
A statement by Doctors Against Genocide which reads: To all international humanitarian organizations, The situation in Gaza is spiraling beyond any medical or moral threshold. The limited stock of intravenous fluids in our hospitals is no longer sufficient to treat the waves of starving individuals arriving at emergency units — from infants to the elderly, they are collapsing from pure exhaustion and hunger. This is no longer just a humanitarian crisis. It is a deliberate, systematic starvation of an entire population. We urge you — Speak. Act. Intervene. Nasser Medical Complex

Over 120 mRNA cancer trials are now at risk as the Trump admin cuts funding & tells researchers to scrub “mRNA” from grant proposals.

What started as COVID fearmongering is now derailing life-saving cancer research.

Hope remains - but scientists say time is running out.

New paper by @njudd.com shows that an additional year of education doesn't causally affect telomere length in old age, despite many (theory) accounts arguing otherwise. It's been desk rejected by 13 journals happy to publish small 'positive' telomere studies. Sigh. www.biorxiv.org/content/10.1...
