If you are planning a vacation you may want to call on Chung-Kuei the Chinese god of travel who offers people protection on their journeys. He can scare away demons and evil spirits and keep you safe on your travels. In Japan he is known as Shoki.

"UK facing ‘brain drain’ of cancer researchers after failure to join EU scheme"

This piece focuses on principal investigators (i.e., grant holders). The bulk of scientific research work is carrried out by postdocs and other soft-money researchers, and the effect on them of Brexit and the removal of free movement needs addressing.

There appears to be zero political will to finalise UK association to Horizon Europe.

@cyrilpedia Good list. As Fortenberry says (in Complete Science Communication): write like a journalist - talk like a caveman.

Importance of noting all clinical observations, even when not intended -> discovery of metoprolol as an IL-6 antagonist... (well, inhibition of IL-6 translation).

Therapeutic benefit in CAR-T cell-associated cytokine release syndrome (CRS).

Intriguing in vitro effect limited to stimulation by CAR-T lysate & not LPS. Hard to know if experiments really comparable, in terms of timing and stimulus

Not only are the Saudis mass murdering Ethiopians, but the Ethiopian regime, not content with committing genocide against Tigrayans, is denying that the Saudis are mass murdering Ethiopians. Both KSA and Ethiopia are invited to join the so-called BRICS while the Saudis are literally shooting Ethiopians for sport. Read this.

"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.
