"We estimate that we have one dinosaur fossil for every 10,000 years"

I hadn't really thought of this before, but it's pretty crazy when you think of it. There were sooooo many dinosaurs and we've found so few. There's just so much about the distant past that we can't know, and that the distant future won't know about us.

I am (or was) an avid cyclist in Chicago and have a lot of opinions on pedestrian safety and car-culture. I think this article shows a lot of good data but doesn't really offer solutions other than "stop being America".

Chicago-centrically, I think things are improving. We've been installing hundreds of miles of protected bike lanes (where the lanes are between parked cars and the sidewalk, instead of between parked cars and moving traffic), and there are so many cycling advocacy groups and such that are active here.

Additionally, during Covid, we saw some pedestrian corridors open up, streets that were closed down to car traffic and setup with outdoor seating and just a general "town square" kind of feel. I really hope we continue that trend and make more investments, as a city and country, in public transit and more pedestrian-focused cities.

I love this idea that most living cells have "innate abilities" and can do things that we're not aware of when constraints are removed/changed.

Very excited to see where these types of explorations take us with regards to human longevity, cancer and brain function fixes, etc.
