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.

MATLAB is optimised to take advantage of vectorisation for mathematical operations between arrays, whereby the processor executes one instruction across multiple variables simultaneously. Vectorisatio...

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? ☕🧐

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

Ever wonder how you read so fast? Your brain gets a head start—processing the next word before your eyes move. Our MEG + eye tracking study out in Nature Communications study from @thechbh.bsky.social reveals orthographic & semantic previews predicting reading speed www.nature.com/articles/s41...

Fast hierarchical processing of orthographic and semantic parafoveal information during natural reading - Nature Communications

Combining MEG, eye-tracking, and representational similarity analysis, this study shows that readers rapidly and sequentially extract orthographic and semantic information from upcoming words before fixation, supporting efficient reading.

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

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.
