Some interesting !
When flies like sit, walk or fly, the gain in their motion vision adapts:

Like many other animals, flies also attenuate expected motion input during turns:

Because mice appear to have similar features, this was considered quite general.
Work in monkeys now challenges that notion:

@brembs @NicoleCRust @albertcardona @PessoaBrain FYI in mice and zebrafish, spontaneous (movement-driven) and stimulus-driven patterns are largely orthogonal, so high-fidelity and high-dimensional visual representations still exist in mouse visual cortex that the mouse can and does use to do complex visual behaviors. I would agree with @NicoleCRust that mouse V1 is more of an association area than in primates, and this association still has to happen somewhere in primates, so hopefully insights from mice can still be useful in that context. (Our paper: https://www.science.org/doi/10.1126/science.aav7893; review: https://www.sciencedirect.com/science/article/pii/S0896627322005888)

If you were to recalibrate, what would you do?

I always suspected I would do something like study those amazing desert ants that navigate via the earth’s magnetic field. But when thinking through the question “How do you want to spend the next 10 years?” more seriously (pretending there are few constraints), that’s not where I actually point myself.

Acknowledging that it’s a tremendously priveleged (and emotional) thought experiment, What would you do with your next 10 years, assuming that thing needs to be useful enough that it’s reasonably supported (and you would continue to get a paycheck)?

TIL the unicorn origami from Blade Runner requires cutting and taping and is made from two squares! Purple is the Blade Runner unicorn, pink is based on Jo Nakashima's model and is more kosher. Tutorials here:

Ugh.

https://www.vulture.com/article/hugo-awards-china-censorship-controversy.html

the volunteer body that administered the 2023 Hugo Awards appeared to have directly engaged in self-censoring the nominees over political concerns about the host country, China. The emails allege members of the Hugo administration team succeeded in keeping certain books off-ballot because they wanted to operate under Chinese laws related to content and censorship

@mrcompletely@heads.social avatar

@NicoleCRust yeah they fucked that up royally. Everyone involved in the decisions needs to go and the 2023 award categories that were impacted should be nullified. Effectively they already are; those awards are illegitimate. The authors who won them should reject them imo, though that's a tough ask.

I did make sure to put some of the censored books on my to read list, so good job with the Streisand Effect I guess

@NicoleCRust oh no :( I recently read Babel (it was very good!)

“I wish to clarify that no reason for Babel’s ineligibility was given to me or my team. I did not decline a nomination, as no nomination was offered … I assume this was a matter of undesirability rather than ineligibility.” (https://www.theguardian.com/books/2024/jan/24/science-fiction-awards-held-in-china-under-fire-for-excluding-authors)

Do psychologists "measure"?

Weird question, right?

"Measurements of attributes such as emotions, well-being, or intelligence are widely used for various purposes in society, but it remains a matter of discussion whether psychological measurement is analogous to measurement in the natural sciences, and to what extent it qualifies as measurement at all.'
https://doi.org/10.1080/09515089.2023.2300693
Edit: author is here! @mieronen

My initial take: what?! This seems silly. But I'm starting to warm up to it. It's about causality. Consider: "insomnia causes fatigue"; no one disputes it. But there's not a physical thing in the world called insomnia that causes a physical thing in the world, fatigue billiard-ball-style. Rather, the physical causal chain happens by way of a lack of sleep causing the brain state that leads to the mind state of fatigue (in other words, that word "cause" is doing some heavy lifting in that phrase). The question is: can you meaningfully talk about causality when you have abstracted away from physical interactions?

On one hand, of course - you can develop causal models formulated entirely at the psychological level (rewards, punishments, surprises, mood) that make falsifiable predictions and you can both perturb and measure these things to test those models.

On the other hand, we probably do need to take some care that we aren't confusing ourselves as we throw around that word "cause" interchangeably for things that physically interact and abstractions of those things.

Thoughts? I'm particularly curious about cases in which this type of abstraction has led researchers astray.

We’re just one day away from International Day of Women and Girls in Science. Is there a woman who inspired you to pursue a career in neuroscience?

Tag her or share your story below.

@thetransmitter

I am where I am today because of my undergraduate research advisor Dr. Akaysha Tang. She was a young female professor in a older male dominated department, who gave us undergrads opportunities often reserved for graduate students. She mentored me on my own independent research projects, sent me to numerous conferences, and taught me how to write papers and give talks. In fact, the only reason that I got into my dream grad school was because of the research experience that Akaysha fostered (my GREs were mediocre and I came from a mid-tier state school). I very likely would not have gone into science at all as a career had it not been for her patient and dedicated mentoring.

This interview with Philip Ball is really good:

I was hoping for a bit more questions on the book, and meaning in biology, but it's interesting to hear about his unique intellectual trajectory. I know very very few people who are as broadly read as Phil.
