Remember: Darwin's note of "I am very poorly today & very stupid & hate everybody & everything" was written on Oct 1 (1861). Thus we are free to celebrate Very Poorly And Very Stupid Hatred Day today.

a PowerPoint slide with the main text: "Madeleine's PhD Defense/Wednesday July 15, 2026/10 AM"
The center of the slide has a logo: circle containing an MS paint cartoon of a deer mouse in a ti'at style plank canoe on the water. The logo also has text: "Evolutionary Genomics of Channel Island Peromyscus". 
There are also several photos and graphics on the slide, clockwise from the top right: me suiting up to go in the ancient DNA lab, mammalogist Jack von Bloeker with future island fox museum specimens, a deer mouse specimen and its removed toe for DNA analysis, a mitochondrial haplotype network, a map of the California Channel Islands, an admixture graph, a subfossil of Peromyscus anyapahensis, and a picture of me subsampling deer mouse specimens at the LA County Natural History Museum.

The tech industry props up the richest people on the planet and pays far less than its fair share of taxes. It can absolutely afford its own R&D. But instead, it’s effectively hijacked our public science infrastructure because having more wealth than anyone could ever spend is still not enough.

More than 10,000 Ph.D. scientists were fired by the Trump administration last year. Grant cuts affected more. "A few dozen got jobs in other countries" is not a serious solution. There are not enough jobs in the whole world. The result will be less science, not the same science just elsewhere.

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...
This line graph illustrates the percentage change in agency staff levels from the previous year for nine major U.S. federal scientific and health organizations between the fiscal years 2016 and 2025. The agencies tracked include the CDC, Department of Energy, EPA, FDA, NASA, NIH, NIST, NOAA, and NSF. For the majority of the timeline between 2016 and 2023, the agencies show relatively stable fluctuations, generally staying within a range of +5% to -5% change per year. However, there is a dramatic and uniform plummet starting in the 2024–25 period. Every agency depicted shows a sharp downward trajectory, with staffing losses ranging from approximately -15% to over -25%. The Environmental Protection Agency (EPA) shows the most significant decline, dropping to roughly -26%, while the National Institute of Standards and Technology (NIST) shows the least severe but still substantial drop at approximately -15%.

Importance: High
perhaps i misunderstood "let's concentrate on you"
Jamaica is bad enough but i have mastered that-at least the danger-4th highest murder rate in the world as for the us i have alienated large stretches of it-i will spare you the details i was amused that you are now friends with JD Watson he single-handedly prevented me from getting a Junior Fellowship at Harvard
In 1972 I got my PhD in Biology and it was conventional to nominate the very best post-docs for a Junior Fellowship, Harvard's most prestigious award-it provided three years of research support without any duties. I was the best student out of Evolutionary and Organismic Biology in more than 20 years. The entire department was behind me.
but Watson was on the 3-man committee, in charge of all the science candidates and he deemed my two papers, reciprocal altruism and parental investment and sexual selection as "not being science" and dismissed me in one sentence. Well bless his soul, he now does not even understand his own subject-yes, i speak of genetics-because having remained resolutely ignorant of evolutionary logic and biology he can neither understand the shape and form of the genotype nor how it differs systematically within life
i have been preparing something for you for a long time on human intelligence, Africa, parasites etc because i prefer to get things right but i am ready to send you what i have main focus is-Africans stupid or smart?“The Worst person you Just Made a Great Point” photo from The Onion meme
