Someone referred to my Brompton's color as periwinkle blue yesterday, and I just realized I can name it the Commodore (after Matthew Calbraith Perry).

Very excited that Blueprint Biosecurity is funding studies that will evaluate the real-world effectiveness of far-UVC light as a pandemic countermeasure! We're looking at infectious flu virus in respiratory particles with and without far-UVC. blueprintbiosecurity.org/building-the...

Yesterday I horrified some Philadelphians by telling them that Bostonians drink iced coffee through the winter, including outside.

SNAP benefits will stop for millions on Nov. 1 due to the U.S. government shutdown. Help send emergency cash to the lowest-income families as soon as their payments are missed: GiveDirectly.org/snap

New episode of HARD DRUGS! AlphaFold, ProteinMPNN & other AI tools are transforming biology and drug design. But how do they work? What can’t they do? And can we use them to make a vaccine against Strep A for the very first time? In this episode, Jacob and I talk about hacking proteins with AI.

Hi. It's me. 2 weeks later. This is done. 58 frames over 3 seconds, *50* layers in the final image. WOO. This was a long edit, felt like ACTUAL work so unless I get it again with the actual sunset I doubt I'll be editing more like this. Psyched for the final piece tho! 🪶

Blue cities should tear up the roads in front of ICE facilities and then start decades of community engagement and input sessions to rebuild them. Let's harness our core competencies.

Is there anything more Sisyphian than checking the "keep me logged in on this device" box?

Just got a Covid vaccine at a CVS in Philly no problem - made an appt online and then was not asked any questions about eligiblity while I was there. 💉💪

Pedestrian walking in road because cyclist riding on sidewalk because car parked in bike lane

You have to constantly stay vigilant when walking in New York at night. Otherwise when there's a cat in someone's window, you might miss it.

NEW: 1km of Montreal’s Ste-Catherine Street will become permanently “pedestrian only” (less than perfect term since it will be a people-place for a LOT more than walking). 225+ new trees, vegetation-covered pits for rain drainage, more seating, illuminated canopy, financial help for businesses, etc.

after sharing our book about making outdoor pigs pay, lots of people are sending us this meme:

Zohran’s citibike numbers make me feel like we need to start demanding bike share stats from our politicians in the same way we demand tax returns

My most memorable parking story is that time they repaved my street in Brooklyn and there were no cars parked on it for a couple days and we met a bunch neighbors across the street who we had never talked to before because the cars had always been in the way.

There’s a new pedestrian-only walkway between Market & JFK and 31st & 32nd–and we’ve painted it with murals. Here’s more about the two murals Branche Coverdale created for Mural Row at Schuylkill Yards! This project is by Brandywine Realty and Mural Arts, and it was curated by Conrad Benner.

One of the (many) things I love about Bryant is that it was a completely average American street (2 way traffic, 2 side car parking). Most streets in the U.S. have plenty of space for protected bikeways. We just need to make safety (for all road users) a priority. Here’s Bryant before:

happy 2 years to the Boston Cop Slide

Feeling called out

Safety is more important than aesthetics, but a general reminder that concrete can be beautiful, as seen on Atlanta's Midtown bike lane : www.jonesyartatl.com/midtownbikel...

Gay Jawn. Protect Trans Youth! (Spotted in South Philly) 🦅🏳️‍⚧️🏳️‍🌈

I'm so glad Boston finally decided that drivers flipping over their cars when they hit these barriers is a driving skill issue, not a liability/flaw with protective infrastructure from cars

This is a Hall of Fame reader comment on a very reactionary op-ed about Zohran Mamdani's victory that was published in my local paper today.

It's hot today - and even more deadly tomorrow. Reminder: WBGT (wet bulb globe temp) shows true daytime heat risk outdoors. Left: air temp (looks hot but manageable) Right: WBGT (shows how truly deadly it will be across wide swath of U.S.) What's WBGT? www.washingtonpost.com/opinions/202...

Did you know that Philly's first Juneteenth mural is located at 6228 Germantown Avenue on the Germantown ArtHaus? The mural was created by Lead Artists Keisha Whatley and Andre Chaney, along with Assisting Artists Khalid Dennis and Donna Grace Kroh.

trans rights btw this isn't up for debate

Here's a photo of Max smiling at the park

Earlier this year, I explained why I donated 16% of my annual income directly to help save USAID programs that were terminated. Now there's an easy way to do that. This Response Fund pools donations directly to urgent and vetted programs in need of support: proimpact.tools/rapid-response

Whoa, Integral was bought by Electric Bike Company and they're getting rid of existing stock to make room for new models. You can get a longtail with hydraulic brakes, TWO batteries, front rack, etc. for $999 ($1275 w/ cushions and guardrail). integralelectrics.com/products/the...

We're making viruses from public opinions! At #GERF2025 we're asking the public if they would take part in a human challenge study: green for yes, red for no, and blue for maybe. The mix of opinions is fascinating and it's clear there's a hunger to know more! 🧪@imperialinfect.bsky.social, @cepi.net
