Part Three: Taking rationality seriously | Meta-rationality

A pragmatic understanding of how systematic rationality works in practice can help you level up your technical work.

iGluSnFR3 is published! Check it out⬇️

We made a new glutamate indicator with improved sensitivity, kinetics & localization for imaging synaptic transmission.

This is #iGluSnFR3 in action detecting minis w/ TTX.

Glutamate indicators with improved activation kinetics and localization for imaging synaptic transmission - Nature Methods

iGluSnFR variants with improved signal-to-noise ratios and targeting to postsynaptic sites have been developed, enabling the analysis of glutamatergic neurotransmission in vivo as illustrated in the mouse visual and somatosensory cortex.

Dendritic dynamics as fireworks show 🎆🤯

When an "imaging artifact" turns out to be one of the wildest things we've ever observed in the universe.

A supermassive black hole.
Ejected from its galaxy.
Compressed gas in its wake.
AND FORMED A 200,000 LIGHT-YEAR LONG STRING OF STARS.

WHAT. https://twitter.com/HubbleTelescope/status/1643978146532974594

“Hubble observed a curious linear feature that was first dismissed as an imaging artifact from the telescope’s cameras. But follow-up observations reveal it is a 200,000-light-year-long chain of young blue stars created in the wake of a runaway black hole: https://t.co/l9ZiR0EeRX”

We then quantified 1) the absolute magnitude of color and shape information using normalized Euclidean distance, and 2) the relative dominance of color and shape information, using a shape dominance index that we devised for this purpose. 4/
Specifically, we presented stimuli varying based on their color and either orientation or curvature both to human fMRI participants (looking at areas V1-V4, and LOC), and to various CNNs trained on object recognition. 3/
