Wonderful opportunity to read for a PhD with two of the most amazing cognitive and computational neuroscientists around!

My 5-year-old is playing "Australopithecus" (pronounced correctly). This is pure luck of the draw, but expect a smug book on how to parent in a bookshop near you soon.

Great example! I'm going to steal this from my ever-increasing repository of gross parenting situations; thanks!

After previously showing kids are gross (see doi.org/10.1177/2398...), we now find that parents get used to it! After starting the weaning process, they stop avoiding soiled diapers. This disgust habituation even generalises beyond child-specific stimuli.

Parents stop finding diapers disgusting once babies are eating solids The extent to which parents feel disgust appears to come and go, which could be important for their children's health

If you'd like a more accessible write-up, @newscientist.com did an excellent article on the study: www.newscientist.com/article/2462...

Or if you prefer digestible science podcasts, @npr.org Short Wave featured it today: www.npr.org/2026/01/23/n...

Relatively low-quality (student project) electrogastrography data for testing analysis pipelines

Hahaha! I don't have a clear example directly at hand, there's a dataset here: doi.org/10.5281/zeno... Traces are in columns labelled "eeg_[i]". It's part of this preprint on EGG methodology: doi.org/10.48550/arX...

If youโ€™d like further distraction from your analysis, ponder electrogastrography. The stomachโ€™s pacemaker operates at 3 cpm, but we frequently pick up peaks at 6 and 9 cpm too. Harmonics? Pyloric activity? Signal bleed from intestines? WHO KNOWS ๐Ÿคท

Zenodo is fantastic for this! You can use it to permanently host a snapshot of a GitHub repo (by creating a Release). You can do with the repo what you like (e.g. update later) without impacting the deposited code, and Zenodo meets journal requirements for code and data deposit.

Lovely overview! Great to see other applications mentioned. (I used my visual working memory tools in pigeon navigation: doi.org/10.1371/jour...)

Hahah, sorry, I didnโ€™t mean โ€œjustโ€ as โ€œonly socksโ€! It was an expression of surprise that adding socks and other useful stuff was a genuine possibility. This will forever change out party bags. (Which, honestly, were already quite amazing due to my wifeโ€™s creativity.)

Iโ€™m sorry; it sounds very stressful and demoralising. Itโ€™s such a terrible illness. Hope this round wonโ€™t be as bad as expected, and that you come out the other end.

Such exceptions exist because 1) If enough people get it wrong enough of the time, it becomes accepted. 2) Historical weirdness is often grandfathered in. 3) English is actually three languages in a trench coat.

That fact that itโ€™s the de facto lingua franca is a historical fluke (and a mistake).

Only a native speaker could be so confidently wrong about their own language ๐Ÿ˜œ

For anyone else: the doubling-up rule suggests "focussed" as the correct version. However, in reality both "focussed" and "focused" are both accepted ways of spelling it.

06.01.2026 17:21 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

I was 2 characters over the limit in a box on a grant proposal, so I did what any self-disrespecting English speaker would: removed the additional Ss (e.g. "focussed") and Us (e.g. "behaviour"). Now Iโ€™m 2 characters under.

I might apply for citizenship at some point, so nobody tell the Home Office!

Definitely true for a lot of my work, but at least I produce hand-crafted artisanal research blunders. Instead, this is auto-generated slop that sounds like the early stages of a spin-out company riding the AI bubble.

Regardless, I thought it offered nice context, even if not (as) problematic :)

This is beside your point, but I participated in this and the suggestions were gobshite.

So in addition to all of the objections you rightfully raise, the whole thing theyโ€™re testing is absolutely useless.

Also, while making light of this helps ridicule its dimwitted billionaire owner, the fact that Twitter now openly allows and encourages revenge porn is absolutely nuts. (Not to mention legally questionable in many countries: the UKโ€™s intimate image abuse rules explicitly include realistic fakes.)

I left Twitter when Musk took over, and havenโ€™t really kept up since. It looks like theyโ€™ve added two more Xs?

If I recall correctly, NICE guidelines come with similar warning. I assume itโ€™s a liability thing.

So I looked at NICE to check, and now thereโ€™s a whole EULA to agree with: cks.nice.org.uk This one reads more like copyright (and AI?) protection.

If youโ€™re wondering why your friends in academia are a little on edge right now, itโ€™s because an eighteen-year-old who hasnโ€™t done the reading, doesnโ€™t look at the assignment, and has does no critical thinking skills more complex than โ€œbecause I think itโ€™s in the Bibleโ€ can literally end your career
