I'm disgusted by the hyperbole but relieved the story is a lie.

No, dire wolves haven't been brought back from extinction, and I don't believe any species should be, at least for now.

We are careless and irresponsible and restoring extinct species will have negative unintended consequences that outweigh all possible positive consequences.

Happy birthday to Canadian 🇨🇦 geneticist Irene Ayako Uchida (1917-2013)! In my #linocut Uchida is shown surrounded by chromosones, with anomalies (shown with pink arrows) due to radiation exposure, based on one of her research papers. A strand of DNA is hidden in the image (as her watchband).⁠
⁠
Uchida didn’t set out to be a scientist. She was studying English literature at UBC, before she was interned 🧵1/n

Linocut portrait of geneticist Irene Ayako Uchida (handsome, middle age woman of Japanese heritage with curly hair with a white streak on her right temple, with an open, thoughtful face) leaning on folded arms in a white button down shirt with a small watch with double-helix watchband on her wrist, in dark teal-grey ink. She is surrounded by chromosomes in gold, from one of her papers. The anomalous ones are pointed out with small pink arrows.

The Return of the Dire Wolf

The dire wolf once roamed an American range that extended as far south as Venezuela and as far north as Canada, but not a single one has been seen in over 10,000 years, when the species went extinct. Plenty of dire wolf remains have been discovered across the Americas, however, and that presented an opportunity for a company named Colossal Biosciences.

And...I'm not sure this is a good idea...

Before my wife's chronic migraine, she was deeply involved in genealogy.
For my family history, she actually found where my paternal great-grandmother was on the Dawes Rolls. She was 1/4 Choctaw which makes me 1/32 Choctaw. I think I'm also 1/128 Cherokee but we can't find the evidence since that would be quite far back.
Anyway, that makes my dad verifiably 1/16 Choctaw.
What's interesting is that he took a DNA test and it found 0% Native American DNA. Genetics and heredity is weird like that since you only get half of each parent's DNA.

I'm not obscene enough to start claiming my "Native American Heritage" for 1/32 and a life that was lived entirely as an entitled white person.

Can't wait for #Orban, and consequently #Putin, to get hold of this:

»This will enable secure #automated exchanges of #fingerprints, #DNA profiles, #vehicle registration data, #facial images, and police #records through EU routers.

After a long journey, finally, my good friend Sai and coworkers published this amazing work in #NatCommun. 🎉

They can use native functional groups such as alcohols and transform them to the most challenging Z-olefins.

Without the use of a transition metal catalyst, and even working for #DNA 🧬 functionalization!
