Finally PhinisheD!!! Successfully defended my dissertation on Evolutionary Genomics of Channel Island Peromyscus this Wednesday 🐭🧬👩‍🔬 Enormously grateful for the support of my family, friends, labmates, collaborators, and amazing committee members for seeing me through the last 6 years!!!

big things happening: I'll be defending my dissertation next week on July 15! to procrastinate preparing, I will be posting a meme for each of my chapters until the big day. also, please DM me if you'd like a zoom link to attend my public defense, but be prepared for 45 minutes of mouse toe talk!

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.

In the face of ongoing pressures and critique (including here by many), the public reaffirmation of the core mission of the National Academy of Sciences is a much-needed signal from incoming NAS President Neil Shubin. www.science.org/doi/10.1126/...

The enduring pursuit of science in America

Imagine an American organization that convenes scientific experts not to advance any ideology or interest but to provide the nation with a clear understanding of complex problems. Imagine this body wo...

Not wanting to be snarky but this is true of every technological advance in science. My entire PhD in 1983 was the fitting and refinement of a single protein crystal structure. Today I could do the same within an hour - no AI required. Hyperbole does not help.

Artificial intelligence systems will allow a single PhD student’s output to match that of a whole laboratory, according to Demis Hassabis, a Nobel laureate for chemistry.

amazing thread about our latest paper, out in Therya today!! really cool and unexpected find from my Channel Island mouse dissertation research. thanks @kaycebell.bsky.social for all your detective work in the collections!

New paper out today! I had the good fortune to work with this crew, @mabscientist.bsky.social, Susette Castañeda-Rico and others, on a project that discovered previously unknown introduced mice on the Channel Islands in California.

Art of the ancient Americas may not be your thing, but you have to love this earthenware crab vessel. I'm sorry, I don't make the rules. 🦀 This is going into our imaginary museum replica store, pronto. #LACMA Colombia, Calima style, Ilama period, ca. 1500 BCE-100 CE. 🏺 1/ 📸 me

Earthenware crab vessel with two spouts flanking a round handle on its back. It's painted a reddish-orange color and its stumpy claws are closed in front of its cute little face. It's standing up on its six non-claw legs, which are also stumpy. Insanely adorable.

I implore everyone to read this brilliant book review of Kathryn Paige Harden new book on the genetics of criminality. It cuts right through the bullshit to state plainly what Harden's project really is: eugenics bullshit and grifting lareviewofbooks.org/article/orig...

Natural Election | Los Angeles Review of Books

Kathryn Paige Harden’s new book offers a defense of a kind of Scientific Calvinism that converges with the eugenicist ideals of the contemporary Far Right.

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.

I am shocked to see this language from the NSF. “The U.S. National Science Foundation's Fiscal Year 2027 Budget Request reflects a strategic alignment of resources in a constrained fiscal environment while eliminating woke and weaponized grant programs that previously funded radical DEI projects.”

So, um... this is bad. Really bad. I looked at the letters that were translated by the AI, and the very first one I found was almost entirely hallucination. Thread:

The new project mapping 7,000+ ancient letters is impressive: romanletters.org . The database & geolocation (although noting Pleiades rather than just AWMC would be nice) are great. But I absolutely cannot get over use of AI—however transparent—for translation. 🚨 Value human translators 🚨

AI translation transparency
Modern English translations were produced using Claude (Anthropic), working from either the Latin/Greek original or an existing 19th-century English version. Translation work was guided by two internal documents: a translation guide covering late antique epistolary conventions, rhetorical register, and how to handle common formulaic phrases; and a modern voice guide specifying tone, vocabulary level, and how to avoid archaism while remaining faithful to the original.
Al-generated translations are clearly marked in the interface. They are provided for accessibility and research convenience, not as authoritative scholarly translations. The original Latin or Greek is preserved alongside every translation, and 19th-century English versions are shown where available. Corrections from domain experts are
welcome.

The genome isn't a blueprint. But what is it? I originally imagined this as a reported feature on metaphors of the genome, but it ended up being an essay. And at the end I share the metaphor I personally ended up landing on. If you want to tell me why it is wrong, you'll need to read the story ;)🧪

There’s a wolf in LA for the first time in 100 years. A collared gray wolf entered the mountains of north Los Angeles County yesterday. Known as “BEY03F” she traveled hundreds of miles from her pack in Plumas County crossing highways, mountains, creeks and valleys. www.latimes.com/environment/...

A wolf has come to Los Angeles County for the first time in more than a century

Around 6 a.m. Saturday, the 3-year-old female arrived in the mountains north of Santa Clarita, as tracked by a GPS collar.

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.

Dozens of researchers will move to France from US following high-profile bid to lure talent

Large proportion worked at Columbia University, which had its grants cut and frozen by the administration of US President Donald Trump.

Hot take: folks are too focused on the AI emphasis of the PRFB & missing the most concerning part of the solicitation. The heavy emphasis on bio-AI integration for “technological advances” is a concerning degradation of NSFs mission to fund basic biological research.

The National Science Foundation sign on our Eisenhower Av building is now gone. The NSF mural in the foyer is removed and torn off in sheets. We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

NSF building on Eisenhower Av. HUD now owns. Destroying the NSF mural in the foyer. Of the Eisenhower building.
