1/ A longtime Wired editor just wrote a mush-brained essay about how he totally missed the political rot of Silicon Valley (& still doesn't get it). But in the late 1990s, a Wired journalist warned of a toxic ideology bubbling up from tech. Paulina Borsook has largely been erased. Let's change that

1 To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised! 🧵Thread on our new preprint with

Public info institution the BoM never mentions fossil-fuelled global heating, even during mega-droughts, heatwaves, bushfires floods. Why? Perhaps because its board is controlled by Shell, Santos, Woodside & Chevron? If you think this stinks, make a subsmission!

Human impacts on large mammals went well beyond triggering late Quaternary mass extinctions. A new paper by Brook et al. showing that biogeographic patterns were erased by the spread of domesticated species:

A related paper is in press. Stay tuned.

Missing data and the problem of handling variable-incomplete datasets is a common feature of ecological, evolutionary, biogeographical and palaeontological analyses. Here is a refreshing review arguing for the application of a generalized "Multiple Imputation" Rubin (1976) procedure 👇

Do we know the number of neurons in the human brain? A typical value cited in the literature is 86 billion. However, as I argue in this essay, the data does not justify this number and we do not have yet a satisfactory answer
