English physician and scientist Edward Jenner died #OTD in 1823.

The terms vaccine and vaccination are derived from Variolae vaccinae, the term devised by Jenner to denote cowpox. He used it in 1798 in the title of his Inquiry into the Variolae vaccinae known as the Cow Pox, in which he described the protective effect of cowpox against smallpox. In the West, Jenner is often called "the father of immunology", & his work is said to have saved "more lives than any other man".

"Here we present ancient DNA evidence of a pre-Columbian New World treponematosis by reconstructing a high-coverage T. pallidum genome retrieved from nearly 2,000-year-old Brazilian indigenous human remains, along with three low-coverage genomes from the same spatiotemporal context."

"Using metallurgical technologies from the Wadi Arabah (Jordan/Israel) as a case study, we demonstrate a gradual technological development (13th-10th c. BCE) followed by a human agency-triggered punctuated “leap” (late-10th c. BCE) simultaneously across the entire region (an area of ~2000 km2)."

"Notably, we demonstrated through AlphaGeometry a neuro-symbolic approach for theorem proving by means of large-scale exploration from scratch, sidestepping the need for human-annotated proof examples and human-curated problem statements."

"The team used a sophisticated statistical technique, latent profile analysis, to identify clusters of biomarker activity. Three groups were identified and labelled as low risk to health, moderate risk, and high risk. The researchers then looked at how earlier exposure to stressful circumstances might affect people’s likelihood of being in the high-risk group." ucl.ac.uk/news/2024/jan/financ @science @biology

That’s a massive jump from the four decades prior to the pandemic, when profits drove just 11% of price growth. “

"The following article provides a mathematical analysis of the paradox, explains its role in causal reasoning and inference, compares theories of what makes the paradox seem paradoxical, and surveys its applications in different domains."

"Governments have put future bans on the sale of internal combustion engines, but recently we’ve seen politicians backtracking a little on the issue. Also, there are still huge infrastructure and cost challenges ahead for EVs. So, are reports about the death of the internal combustion engine a little premature?" youtu.be/i8iHzXHt9iw @engineering
