This graph took me 3 years to make. It's perhaps the largest-ever #metaanalysis of #TMS #BrainStim data. It includes my first real scientific discovery 🧵: When you stimulate the hand with a brief electric pulse, your brain and spinal cord are momentarily less excitable: muscle output decreases 1/n

The report “Preserving Our Humanity, Supporting Our Students: Doctoral Advising in Mathematics” by the Teaching Working Group of the Association for Human Mathematics #AHM just dropped! Spread it far and wide! 🫳📄 www.ahmath.org/doctoraladvi...

One thing that has genuinely shocked me over the past year is how many faculty are now using LLMs for nearly every part of their jobs. Not as tools to assist their thinking, but to offload the entire job itself. 1/7

Trouble with AI? Do you need to AI your AI? Are you having AI problems AIing your AI? Do you need AI to AI the AI in your AI? Then we're here to help. Just AI AI to A I A I and we'll AI the rest. Saitaisfaictaion guairainteed. #AI

Your monthly reminder that if you're using ChatGPT to do your science, you're failing your colleagues, community, and all of us. Here, ChatGPT makes up data and presents it as the real thing — then apologizes when confronted.

Do students read anymore? When we assign a book chapter or an article, do students read it, or do they just ask something to summarise it? Genuine question, motivated by my teaching today. If you have a view, please reply 🙏 👇

Who should I follow to see critical perspectives on published qualitative research with a focus on flawed methods? Thanks!

This week, NIH advisors rebuked RFK for harming #NIH and US science. Sheryl Gay Stolberg reported it. Then RFK posted calling her sources anonymous or corrupt. I'll say this hoping it does good: I'm an NIH scientist, I'm not anonymous, and RFK Jr is destroying NIH. More in attachment:

"Neuroscience" does not feature as a research sub-field in this new list of numbers 🧠🤔. (Seems like Ioannidis has had a 'problem' with neuroscience for a while - since the (very poor) hatchet-job they did on us in Button et al. 2013) Ho hum. Guess understanding the brain is so very 20th century...

Government support for drilling at #Jackdaw takes a wrecking ball to any pretence of UK climate leadership & pours fuel on an overheating world - and for what? It’s equivalent to just 2 months of UK gas demand, creates just 27 direct jobs & has *no* impact on energy bills🧵1/4

Totally normal behaviour from one of the leading scientific organisations in the world.

The next TMSMultiLab meeting: 30th October, 16h UK time (GMT, after clocks go back): Dr Antonio Capozio "Who is Afraid of Brain Stimulation? Acoustic Startle Contributes to Variability in Motor Evoked Potentials" Meeting link is available via our Slack channel & github page #TMS #Brainstim ⚡️🧠🧲

Panopto (video/audio lecture capture tool) seems to have been hacked (or LLM'd), this is quite insane. Thank you, Computers 🙏

Or: don't outsource thinking. If your academic writing is absent of thought, then what value is being created by the act? If, instead, writing forces you to engage with the subject and truly *think* about what you are saying and why, then having an LLM do it is absurd.

Liquidambar leaf palette. This tree puts on such a stunning show in October. If you know of one growing near you maybe go and visit it -they look like a sycamore or maple that’s part of a Pride parade…intense leafy dopamine fireworks 🍁:

SE / SD confusion is one of the most common errors in scientific papers, and it messes up all meta-analyses that use the data. Cross-check *every* effect-size you add to your meta-analyses 👇

Thank you François for writing things so clearly and showing us we're not alone. lookingup.francois-rincon.org/an-open-lett...

LinkedIN just moved the Notification button on my Android without any warning. If only there was a place they could notify you about changes to the app 🤔

Harvard just dropped a study AI productivity in software engineering and it found the average increase in productivity from using Claude code is.....zero and for exactly the reasons you'd think fion.ac/jellyfish.pdf

24 month FT Research Assistant role with the excellent Dr Victoria Newell on a project to refine, validate, and implement the Self-Harm Questionnaire – Autism (SHQ-A), a new assessment tool co-developed with autistic people. Details here... jobs.nottingham.ac.uk/vacancy.aspx...

My next door neighbour's house is for sale; the main photo on the estate agent's website is 'AI'-manipulated, with nonexistent lush green grass, shadows in three different directions, weird blurry patches, paths & drains appearing in the wrong places. Which house-buyer will be fooled by this #slop?

People ARE worried - but will it change how we travel? Here's the thing: staying grounded is one of the most powerful things we can actually do. Worry is a start. Action matters more. 🌎💚

"You're absolutely right: I incorrectly described a Chinese cargo in the Middle East as 'nuclear' when in fact it was 'unclear'. You deployed the Navy Seals. That's on me." "Is there another cargo that I can help you with? Or perhaps I can declare intercontinental thermonuclear war for you?" #LLM

Go see Mr Spicer on Tour now: you'll laugh your mouth off.

Whoever's putting hot honey on everything can you please stop?
