Deb Chachra @debcha.bsky.social · 04/10/2026As I’ve written elsewhere, if you pride yourself on your intelligence and discernment, one very important reason to be aware of societal and your own implicit biases is that it keeps you from saying ahistorical, easily falsifiable, or just plain stupid shit. 110
Deb Chachra @debcha.bsky.social · 04/10/2026I have a soft spot for the black-crowned night heron, because I first saw one in the Charles River while walking to MIT twenty-odd years ago and was, “what is that?” Seeing them in the city is such a wonderful indicator of how the river’s been cleaned up. www.cambridgeday.com/2021/10/02/a...cambridgeday.comAlways dinner for black-crowned night-herons, wading into the hunt when other birds are asleepBlack-crowned night-herons live in Massachusetts wetlands, calling “kwok" in the darkness as they fly at dusk to their hunting sites.

It really is a complement/follow-up to HOW INFRASTRUCTURE WORKS (thinking about matter and bodies, vs energy and networks), in part because I always get asked, “so what about lithium?” I’m pretty excited I get to dig into these ideas in a sustained way. 140

Deb Chachra @debcha.bsky.social · 03/10/2026Conversely, there are a lot of smart kids in college who’d be happier working with their hands (I’ve taught lots of them) but AFAICT we don’t have great pathways into the trades, especially not for women/NB people. I dream of a Climate Corps-backed analog of my college for the energy transition. 0111
Deb Chachra @debcha.bsky.social · 03/10/2026Yeah, I’m assuming that’s the same mechanism that Seattle is using, and I suspect many more cities have block party permits than advertise them as Halloween closures. 020

Deb Chachra @debcha.bsky.social · 30/09/2026I mean — there’s been a bunch of new historical scholarship (like in the last 20 years) that reflects the experiences of colonized peoples, and a lot of that is truly fucking horrifying.

Deb Chachra @debcha.bsky.social · 30/09/2026The thing about being me is that you think i) non-toxic batteries for biomedical applications are cool as hell, and ii) a world where dead batteries get tossed onto a compost pile instead of being e-waste is even cooler. 1364
Deb Chachra @debcha.bsky.social · 30/09/2026The thing about having a radiologist friend like @gammacounter.bsky.social is that you will learn, in incredibly well-documented detail, how dangerously life-threatening swallowing button batteries are to kids.
