Individual Choices Won’t Fix America’s Public Schools

I love how genomic analyses keep dismantling the concept that species cannot interbreed. Even better, ancient introgression often facilitates diversity in a domestic context. New paper shows this is in pigs too! www.science.org/doi/epdf/10.... A thrill to be a small part of a giant piggy effort!

Ancient introgression drives wild boar expansion and phenotypic diversification of domestic pigs
Despite the ubiquity of wild boar populations across Eurasia, their origins, routes of dispersal, and phenotypic evolution remain uncertain. Here, using 745 genomes representing populations across Eur...

In 2023, @nature.com published 'Papers and patents are becoming less disruptive over time', receiving world-wide media attention. Our Matters Arising, published after a 32 month delay (more on that soon), shows that the reported decline can largely be attributed to dataset artefacts. 🧵

I am sick of some media uncritically repeating Rand Paul's misrepresentation of Fauci's journal about the Huanan market. In late Jan 2020, it was a common commentary that the market may not be the origin of the outbreak, b/c of a Lancet paper on early cases ▫️1/6 www.paul.senate.gov/wp-content/u...
It now appears using epi data and genomic data that the first infection was in early
December and was not connected to the market. The infections spread among people
weeks before the Chinese reported that they were dealing with a new infection and that
gave the virus time to establish itself in multigenerational (sustained) spread.
Remember, early on the Chinese were saying that there is no human to human
transmission and all the original 27 cases were from the market. Now we know the
market was not the source, it was the amplifier. Having said that, somewhere the virus
jumped from animals to humans.
