How do we fix academia's air travel problem?
I've been declining invites in order to avoid flying and it feels weird at first but in my experience, organizers are very understanding and many will allow a virtual presentation.

Fellow dudes.
We eat a lot of beef.
Eating less beef and more of nearly anything else would greatly reduce the climate impacts of our food choices.
And we can still be manly men.

Eating less beef is a climate solution. Here's why that's hard for some American men
Climate researchers have long grappled with how to get Americans to eat less beef, a food with a huge global warming impact. Now some are thinking about it through the lens of gender.

Electric brain signals (spikes, LFP, ECoG, EEG) are typically modeled statistically. But biophysical forward modeling starting with neurons is an alternative.

What's with the Bluesky algorithm? Despite having indicated about 30 times that I'm not interested in posts of people saying they're supposed to write a manuscript or are writing or editing a book, or asking for book suggestions, this is the main kind of post it keeps feeding me.
