🎉 New paper alert! 🧠 The velocity-curvature power law is one of the 'kinematic laws of nature' (Flash 2021), a 'fundamental law of human control' (Zago et al. 2016), and one of the 'kinematic regularities' (Frith & Frith 2023) thought to underlie all biological motion.

1/3 How do you correct for multiple comparisons? Do you take into account *all* comparisons that can render the paper publishable? Most of us don’t. In this NHB piece, Yoav Benjamini, Yoav Zeevi and I argue that it’s time to change our practices >>

I’m claiming I knew the MATLAB ones and that my code is a model of efficiency! 😅 But the Python and R tricks? Total revelation 🤯 – days will be saved!

Very reasonable, I am sure we can all agree!
The RPC-SIG document hard-won wisdom 💡 with tweaks in R, C/C++/Python, Fortran and MATLAB, to help us squeeze out every last drop of efficiency 🧃

Whether you’re on Big Iron 🏗️ or MATLAB Mobile on your iPhone 📱, these tips are gold.

Well if you want more bespoke code, you’re in luck 🍀 — the Society of Research Software Engineers (🔗 society-rse.org) has an RPC Special Interest Group 👀 🔗 sig-rpc.github.io
It's all 'High Performance Computing this' 🧠, 'supercomputing cluster that' 🖥️, and embarrassingly parallel* code on Big Iron 💪 these days…
But what about a more understated, perhaps quintessentially British 🇬🇧, Reasonable Performance Computing? ☕🧐

Perfect for making those publication-ready figures that'll keep reviewer 2 from throwing shade!😎 📈💯
You can play with it right now even without MATLAB. Most users' submissions can open in MATLAB Online by clicking the "Open in MATLAB Online" button such as in the link above – or directly: matlab.mathworks.com/open/fileexc...

Wish I had seen this MATLAB function a few months ago when reviewer 2 said my plots were placeholders at best! 😅📊

Ever needed to visualise overlapping data regions with proper transparency and clean legends? Javier's 😎 ‘shade’ is an absolute lifesaver - showing overlapping bounded regions without turning your figure into an illegible mess 🎨✨

TIL that the aggro af wasps you see in late summer are worker wasps who have finished their nest tasks and are all out seeking sweet stuff and raising hell for the locals with the last days of their lives while waiting to die, wasps are basically just the insect version of retired Brits in Spain

I clearly had a lot of thoughts/feelings from reading Terry's blog post, so I wrote one of my own

It ended up being a bit of a stream-of-thought post but I think it captures some of my worries

ReplicationResearch.org is now open for submissions!

Submit replications and reproductions from many different fields, as well as conceptual contributions. With diamond OA, open and citable peer review reports, and reproducibility checks, we push the boundaries of open and fair publishing.

Please spread the word! I am recruiting a PhD student this cycle (Fall 2026 start) to join my team in a new venture: the neuroscience of mood.

If you are curious to learn more, this short talk provides a good overview of why, what and how.
