I've used Lavaan almost every (work)day for 15 years, but this open source labour of love has never received proper institutional support. I'm delighted to be a small part of an 1.5M OpenScienceNL award, led by Jorgensen, to completely revamp and futureproof Lavaan www.openscience.nl/en/news/45-p...

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

Very jealous following the FLUX conferences from afar - If you are attending, don't miss @jordyvanlangen.bsky.social's poster (F65) on our CODEC project later today! And of course, tomorrow morning a double act by @leacmichel.bsky.social

My favourite Ebert sentence for a 1.5 star review: "Pearl Harbor is a two-hour movie squeezed into three hours". This opening paragraph should be framed.

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...

Zand Scholten has a nice chapter (5) on this here. TLDR; if it isn't a crossing interaction, measurement assumptions can mess up your inferences pure.uva.nl/ws/files/122...

Bonus by @leacmichel.bsky.social - this is apparently the face I make when I am secretly screenshotting a zoom call. Be warned.

Today at labmeeting I was surprised by a celebration of the 10 year anniversary of starting my own group! lab members made funny slides, a sash (which I had to wear), videos from former lab members, and a lovely lunch. What a pleasure to work with so many smart, funny and inspiring scientists.

My book of the (last) year - Light Eaters by @zoeschlanger.bsky.social. beautiful writing, amazing insights and new findings about what plants can and can't do, and a vivid picture of the struggles at the cutting edge of science. perfect.

we had a conceptually adjacent issue with *composite* variables, eg what looks like a mediation for the composite (eg grey matter volume) but is actually only a1 and b2 (or vice versa) for the two constituents of volume, so no 'causal' path. same ideas hold for sum score. osf.io/preprints/ps...

Yesterday we had a shared labmeeting with @anne-urai.bsky.social's lab in the trippenhuis. it is always so inspiring to hear about different (as well as convergent) approaches to our core question, and discuss them with people just as excited about them as we are!

But that's not all - These wonderful people at Reading University with extra time on their hands replicated the machine with modern materials and showed it actually worked (ish) with modern 'imaging' task #neuroskyence

The most amazing thing? It actually worked! His original measurements showed rhythmic fluctuations. there is a nice historical overview here, and the original balance is still on display in Turin

This is a schematic of the first 'neuroimaging' machine, developed by Angelo Mosso in 1882. It was a very carefully calibrated balance, which aimed to measure small changes in the balance due to changes in blood flow. #neuroskyence #psychscisky
