How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller?
Excited to share our latest work in @science.org on a new small polymerase.

Happy end
Not something you see in textbooks very often: tripolar mitosis.
No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.
Which just makes me want to share it again: www.nature.com/articles/d41...

Walz: "To Americans who are watching this, I've got a question for you: What side do you want to be on? The side of an all powerful federal govt that can kill, injury, menace, & kidnap its citizens off the streets? Or on the side of a nurse at the VA hospital who died bearing witness to such govt?"
I’m seeing posts from people (outside of MN) about how US citizens should carry their passports.

"The real mystery is why, during a period of mass migration, the number of foreign prisoners hasn't risen by more."
Good piece by @tomcalver.bsky.social (IMO bottom line is that migration/nationality status has little correlation, +be or -ve, with criminality).

While the gospels say that Judas led the Romans to Jesus, a new theory is gaining traction with some Biblical scholars. There is evidence, some say, that Judas merely shared Christ's location on an insecure group chat that accidentally included several Roman officials and journalists.
