On recent melatonin news:

Research can be hypothesis-generating or hypothesis-testing. Establishing effects requires the latter. Mining a database for statistical significance with no experimental design is / can be useful, but it's also not hypothesis-testing, no matter how much data you have.

I’m recruiting a postdoctoral researcher (@mdc-berlin.bsky.social, Berlin 🇩🇪, @niccolozampieri.bsky.social lab) for my @dfg.de -funded project on somatosensory feedback and locomotor control. Please repost and DM me if interested!

Blue Jays!

As an aside, I think it's a pretty good pelvic-thrust simulation in my video.

"clear all" removes the subsequent speed-up. I used to always do clear all but recent versions of Matlab give a nastygram warning when using it.

Any insights into why this is happening? (first run of code in Matlab is much slower than subsequent runs). Normal and expected? Google-fu didn't turn up much.

Google Scholar tool gives extra credit to first and last authors Researchers welcome the initiative, but say it doesn’t go far enough to capture the nuance of researcher productivity and impact.

Seeing some meltdowns over this this morning. To be clear, this is an optional browser extension by creators unaffiliated with Google. GS itself still just reports the vanilla h-index.

Goodhart's Law is among my favorite adages ("when a measure becomes a target, it ceases to be a good measure").

I think "mechanical doping" in cycling is a great engineering problem. Design a motor that:
- Is light enough and powerful enough to add meaningful W/kg
- Is nearly silent
- Does not produce enough heat to be thermally detected
- Can fit in a bike unobtrusively
- Can be turned on/off inconspicuously

Scientists invent eye implant that helps blind patients see again Device helps restore vision to people suffering from advanced macular degeneration

'The device helped 81 per cent of trial participants suffering from advanced age-related macular degeneration (AMD) to achieve clinically meaningful improvements in their vision, according to research published in the New England Journal of Medicine on Monday.'

Competitor enters a major AI competition (RNA folding)
GPU poor so can't train an AI
Builds a "classic" eng pipeline instead. (90s tech)
Wins and beat everyone using DL 💀
Their winning "hybrid" model had an AI in it. Their original one did not and had a higher score
So they won despite the AI 😂

Always satisfying to determine the perfect initial condition 🤩

When I need a Hill muscle model to use/demonstrate in class, despite having ~20 years of various "MusMod.m" files already existing, I like to make one from scratch: keeps it fresh in my head how to do and how to trouble-shoot!

**and as a nerd it's fun.

Is the rumor that Iowa lost to St. Louis by 30 untrue?

I love journals whose policy is not to bother with any formatting minutia (outside of big-picture stuff length limits) until after review, but they are few and far between unfortunately.

I believe this article (Tucker, 1970) was also the origin of the term "Cost of Transport". First I know of in English anyway:

If you don't know of it already, PyDy is a fantastic Python "tool kit" for multibody dynamics. I use it extensively in a graduate course for generating symbolic equations of motion.

And of course:

In my large (biomech) class I use super-heroes to introduce laws of physics by how heroes violate them, these are my four favorites (Optimus Prime gets top billing of course).

The Matlab Script Editor window should be undocked from the rest of Matlab, I will brook no counterarguments.

So far, I'll take Rocco Becht!

I am biased of course, but great dissertation study from Sam Snyder, we miss her!

"Prediction of knee loads during activities of daily living using custom instrumented insoles and machine learning"

It worked pretty well for everything except sit-to-stand.

Excited for this! I don't suppose you know if there will be a US edition? Bloomsbury is only listing a UK edition at the moment.
