Took a late afternoon hike through the woods down to Kyoto with the kids today — I couldn't manage to focus well but there was absolutely a persistent, full-color rainbow streaking through this (ジョロウグモ) spiderweb! About 3 in the afternoon with the sun already getting low.

(an old memory from the Starry Plough in Berkeley, CA)

"…seek a vent in song for the aspirations, the fears and the hopes, the loves and the hatreds engendered by the struggle. Until the movement is marked by the joyous, defiant singing of revolutionary songs, it lacks one of the most distinctive marks of a popular revolutionary movement…"

"the girlfriend of one of the founders of Antifa"

(disclaimer: I am also a card-carrying member of Antifa.)

A still shot of Vel Sartha, a human female with long blond hair and blue eyes, wearing a fur-lined coverall garment, standing on a windswept plain, her gaze intently focused on her interlocutor. She is a character in the serial TV drama "Andor", set in the Star Wars universe. She and her partner Cinta Kaz are founding members of the Rebel Alliance who fight against the Empire at great personal risk. Of course, what I mean by this is: "Antifa" are the good guys, and always have been.

A selenium-binding protein contains the sequence "SELEN…" - OK, not that surprising, I guess.

Are there any unlikely coincidences in a protein sequence akin to the prescient name of Su(var)3-9? A kinase that has "KINASE" as part of its sequence for example.

I’m a USC alum and would be sickened if they agreed to this.

🚨 First pre-print from my team !!

TL;DR: presence of polymorphism (sequence differences between the homologous chromosomes) can *increase* the local rate of recombination in Arabidopsis thaliana, turning cold regions of the genome hot (purple v. grey) !

The recombination frequency (cM/Mb) along chromosome 4 of A. thaliana (female meiosis).

In full hybrids (grey), where polymorphism is distributed all along chromosomes, most crossovers occur in the regions surrounding the Centromere (Cen), and very few at chromosome ends (Tel: telomeres).

In lines where polymorphism is restricted to chromosome ends (purple), the local recombination rate increases drastically, at the expense of the non-polymorphic regions (yellow).

One day, a stranger arrived at the island and said "One of you has blue eyes".

Awesome! We coincidentally all watched some similarly amazing ocean life documentaries in the past few weeks. I got the impression that mastery of drone photography has opened up some new possibilities lately.

I don’t think the central dogma as illustrated by the diagram you posted is challenged by this article.

Just got back from an excellent week-long family trip to Ishigaki island, and despite the passing of a typhoon nearby we thoroughly enjoyed the ocean. This year the suzumedai / スズメダイ (damselfish?) were very bitey, and I came back with a bit less skin on my legs than I started with!
