The Conversation: Forget AI-generated music, this music was composed using DNA sequences. “For me, the collision between molecular biology and art took me to a surprising endpoint: composing music through the editing of DNA sequences. In a soon-to-be-published paper, I detail my method of using digital DNA sequencing to compose music. Rather than having biotech or medical applications, I did […]

Imagine a team of archaeologists excavating a megalithic tomb near Malmö. Everyone's old South Scandinavian peasant stock except for one person who was born to Sardinian immigrants.

Only one of the diggers is closely related to the megalith builders: the Sardinian Swede. Because old South Scandinavian peasant stock only arrived with the Corded Ware culture, long after the tomb was built. Sardinia is the main place where the meg builder genetics survive.

Happy birthday Rosalind Franklin (1920 – 1958), #chemist & x-ray #crystallographer whose x-ray diffraction images were instrumental to discovering double-helix structure of #DNA, made important contributions to #carbon & #virus research, was 1 of the great scientists of the 20th century.⁠

Watson’s bio lead some to (inaccurately) joke, “What did Watson and Crick discover?” “Rosalind Franklin’s notes.” 🧵

🧬 **Genetic history of Scythia**

"_Using high-quality genomic data generated from 131 ancient individuals from Great Scythia and neighboring regions of the Bronze Age and the Iron Age, we established the genetic structure of the Scythians, revealing their diverse origin with major European Bronze Age ancestral components, and genetic traces of migration and invasions._"

"HIV is a relatively new disease. It was only identified in the last century, but the genetic mutation that defends against it has existed for thousands of years. The international research team, led by Professor Simon Rasmussen and senior researcher Kirstine Ravn of the University of Copenhagen’s Novo Nordisk Foundation Center for Basic Metabolic Research (CBMR), confirmed this through the analysis of over 3,000 genomes of ancient and modern humans. The study used a new AI-based method to detect the mutation in the often degraded DNA of ancient bones.

The researchers analyzed DNA from more than 900 ancient people, ranging from the early Mesolithic era to the Viking era. They found that the CCR5 delta 32 mutation emerged abruptly and rapidly spread in human populations, particularly after humans transitioned from a nomadic hunter-gatherer lifestyle to more densely settled agricultural societies. That shift in lifestyle likely put humans in contact with new pathogens, imposing evolutionary pressure that favored individuals with the mutation.

'People with this mutation were better at surviving, likely because it dampened the immune system during a time when humans were exposed to new pathogens,' explained Leonardo Cobuccio, a co-author of the study and postdoctoral researcher at CBMR, in a statement. 'While it might sound negative that the variation disrupts an immune gene, it was probably beneficial. An overly aggressive immune system can be deadly — think of allergic reactions or severe cases of viral infections like COVID-19, where the immune system often causes the damage that kills patients.'

CCR5, the protein affected by the mutation, helps direct immune cells to areas of inflammation within the body. Disabled by the delta 32 mutation, however, it becomes harder for HIV to infect these cells. This discovery has already been put to use in medicine: scientists have used the protective properties of the mutation to successfully treat a handful of HIV patients."

Now here is something that is super super fringey...

Apparently, there is a 'signature' in human DNA that you can only decipher once you reach a certain level of technology development.

Basically, it's as clear as "Made by Joe Googlyeyes and Friends".
It's molecules arranged in such a way that with 0.00000fuckingcerain probability it was done by intelligent action.

Of course, the current scientific orthodoxy is steering away from that shit because there are easier and more fun ways to destroy your academic career.
