"The insect compass system: From theory to circuitry" by Vilimelis et al. 2023 https://www.biorxiv.org/content/10.1101/2023.07.05.547838v2

Interesting insight on extra-genomic contributions to neural circuit architecture:

"we demonstrate that our predicted circuit can emerge naturally using Hebbian plasticity, which means the neural connectivity does not need to be explicitly encoded in the genetic program of the insect but rather can emerge during development."

And particularly:

"we now address another question: whether there might be a reason that insect head direction circuits typically have an eight-column architecture [...] powers of two are easier to generate with replication dynamics than other numbers, because they just require each cell to divide a set number of times."

"The circuits for N = 2 and N = 4 are degenerate – either producing a single dimensional encoding, or two disconnected circuits that do not enforce the required circular topology. N = 8 is the smallest power of two that could result in a non-degenerate circuit. This hints at the possibility that the eight-column architecture is not a chance evolutionary artefact, but rather that it is the genetically simplest circuit capable of performing heading integration."

Brain samples of a thylacine that died in 1880 in Berlin were kept safe by researchers for decades.

Now, as @rsuarezsaa (@UQ_news) they have finally been analysed. https://theconversation.com/a-140-year-old-tassie-tiger-brain-sample-survived-two-world-wars-and-made-it-to-our-lab-heres-what-we-found-210634?utm_term=Autofeed&utm_medium=Social&utm_source=Twitter#Echobox=1692956554

A group of american disability advocates made a short film about how bikes & trikes work well for people with a wide range of disabilities.

So now the deadbird site, formerly known as Twitter, is inviting developers to come back and "build what's next" with the much abused API.

Twitter (and Reddit)'s greed-infused API restrictions wrecked a project we (ASU News Co/Lab) were doing to help journalists send corrections down the same social media pathways as the original journalism.

The idea what we'd ever work with them again is a sick joke.

Great news: Free KN95 masks are now available from public health vending machines in NYC.

This is amazing work! Not everyone can afford to buy high quality masks regularly. If we want more people to wear masks, high quality masks should be available for free everywhere. Having them in public health vending machines in NYC is a great first step!

Emulsifiers are widely present in ultra-processed foods. A new #PLOSBiology study reveals that, in mice, maternal #emulsifier consumption during gestation and lactation leads to metabolic and neural impairments in the offspring. #metabolism #diet

In 1975, Icelandic women earned 40% less than men; today it is only 10%. A "Women's Day Off" strike was held in 1975; 90% of women refused to work. It shut down the country. In response Iceland passed a Gender Equality Act & elected a female president.
