I like to search for evidence of evolution in the genomes of animals, specially birds. Las opiniones aquí abajo son mías. ❤️🧬

A gene within a supergene: An estrogen receptor shapes the behavior of White-throated Sparrow morphs
Expression levels of the estrogen receptor determine aggressive behavior in these songbirds.

On the event of James Watson's death, I highly recommend this 2023 commentary from @matthewcobb.bsky.social and Nathaniel Comfort with crucial new insights into the discovery of the double helix. (And also check out Cobb's brand new biography of Francis Crick) www.nature.com/articles/d41...
What Rosalind Franklin truly contributed to the discovery of DNA’s structure
Franklin was no victim in how the DNA double helix was solved. An overlooked letter and an unpublished news article, both written in 1953, reveal that she was an equal player.

I try to teach my students how to be smarter than AI, and I think that can happen if they learn how “smart” AI is and how they can use it for their purpose. Which means they need to distinguish AI good answers from wrong answers and that leads them to research more and learn. I hope 🤓

I realize broad science-literacy problems cannot generally be solved just by shoving more facts at people but I really wish more people understood that the entire purpose and mechanism of a vaccine is to educate your OWN immune system, making it about the most "natural" medical intervention possible
