I've seen fossils in some remarkable places, but this takes the prize: the benthic foram Nummulites in the base of the Great Pyramid of Giza. These massive blocks were quarried from the Eocene Mokkatam Formation when a relictual population of woolly mammoths still lived on Wrangel Island.

It’s a gloomy day BUT I finally debugged a loop, so here’s a throwback to a favorite bodega cat

(please let me remain ignorant if anything’s happened to Poncha in the last few years bc my partner has sought her out for about a decade of visits and thinks of her as a Hell’s Kitchen landmark)

Thanks so much! I’ll drop a line shortly :)

I know it’s close to the best consideration date, but would you have time to chat about this with me?

Super interesting, but also— what a harrowing punch to the gut

New genome assembly for the golden jackal (Canis aureus)! The species is expanding across Europe due to various selective pressures including anthropogenic change and competition over resources. However, its spread into urban areas could contribute to zoonotic diseases.

On Michigan Cherry Farms, Small Falcons Are Improving Food Safety - Inside Climate News Kestrels are already abundant on local cherry farms, but a new study suggests their presence might lower the risk of food-borne illnesses caused by pathogens from other birds.

A new study by MSU found that providing habitat and nest boxes for kestrels near cherry orchards significantly reduced the risk of food borne illness in humans. Kestrels kept out rodents and small birds that could contaminate fruit with their feces. #goodnews #biodiversity

This is terrific. Writing is a way to think; waiting to write until you've worked everything out is counterproductive. On the discomfort of thinking through writing, from @patthomson.bsky.social

This past week's moth in #YearOfTheMoth is the VAMPIRE MOTH!

It has a sharp snout for drinking juice from fruits, but males evolved to suck mammal blood to collect salt which they then give to females through their sperm! #sciArt

Selective sweep probabilities in spatially expanding populations - Nature Communications In this study, the authors use mathematical modelling and analysis to understand how mutations spread through populations that are expanding in space. The results shed light on the evolution of biolog...

Our paper "Selective sweep probabilities in spatially expanding populations" is out in Nature Communications!

Our work extends the theory of population genetics and contributes to our understanding of cancer evolution.

I’m relieved in a way that it’s not just me. 😅 I recently put out my first paper as corresponding author and had similar frustrations (that chatbot was comically useless and the automatic reformatting of references was downright absurd), but I didn’t know if it was always this bad.

We have more #biodiversity data than ever — from 🛰️, field work, citizen obs., and Indigenous knowledge.

But, are we halting biodiversity loss? The answer is uncertain.
Why? Because the chain of evidence needs to be stronger

Our new #PNAS paper proposes a way forward
www.pnas.org/doi/epdf/10....

Finally published! We first uploaded this preprint in 2022 but dropped it after frustrating reviews.
It was well received and cited, motivating us to revisit it.
We added new content, including simulations and a proof-of-concept genomic green status assessment.

Evaluating the analytical performance of direct-to-consumer gut microbiome testing services - Communications Biology Comparative analysis of DTC gut microbiome testing services reveals significant methodological variability, underscoring the need for standardized reference materials and guidelines to ensure reproducibility and reliability in commercial microbiome testing.

Results and health assessments from gut microbiome home-testing kits vary whether they are produced by the same or different manufacturers. The findings, published in Communications Biology, highlight the need for caution when interpreting or acting on test results, according to the authors. 🧪

Well, well, well… happy International Polar Bear Day!

I searched my zotero library for 'personal communication', because these tend to be interesting and can illustrate how science really works. I was not disappointed, the most recent one in my library was this from @syeducation.bsky.social. More of this! doi.org/10.36850/mr11

Interbreeding between Neanderthals and modern humans was strongly sex biased Sex biases in admixture and other demographic processes are recurrent features throughout human evolution. For admixture between Neanderthals and anatomically modern humans (AMHs), sex bias has been p...

Many living people carry fragments of Neanderthal DNA, remnants of ancient interbreeding events, with uneven distribution across chromosomes. New work by @sarahtishkoff.bsky.social lab suggests patterns are most consistent with Neanderthal contribution to human populations being highly male biased.🧪

Cheekiness aside (and no shade to overwhelmed editorial staff, who were super helpful with each challenge), I genuinely don’t know if this is typical and whether I should account for a similar workload in the future. IS this normal?? Did I maybe get off easy?? Insight appreciated! (4/4)
