We've spent a ton of time talking about teens getting injured on e-bikes (or illegal e-motos). We've heard that crash rates are skyrocketing. Marin County Dept of Health even set up a dashboard to see how many e-bike/e-moto crashes are happening. But how many kids are getting hurt *in cars*? 🧵

Something I often talk about is the need for media outlets to put conversations about e-bike safety and regulations in the context of the larger danger on our streets: cars. The Boston Globe published two letters to the editors that do this well. I'll thread them below.

Say it with me 3 times... E-MOTOS ARE NOT BIKES E-MOTOS ARE NOT BIKES E-MOTOS ARE NOT BIKES velo.outsideonline.com/ebike/ebike-...

A picture is worth a 1000 words. The birth dose of hepatitis B vaccines in the USA eliminated perinatally acquired hepatitis B infection from over 20,000 cases a year before the vaccine was introduced to <20 cases a year. The gaslighting by the current members ACIP is obscene, unethical and cruel.

Abject failure. wapo.st/49WM4BI

I'm sorry, I just have to pop off again on that NYT e-bike piece. The fatality rate for e-bike injuries is 11%?? You're saying that one out of every 9 times someone hurts themselves on an e-bike, they die? That is just so mind-blowingly incorrect, I don't know where to start.

This is actually quite brilliant, up to and including the final sentence 🔥

The state's response to wildly popular e-bikes? Cancel the program and fund more cars. 🤦‍♀️ CARB is ending the EBIP, mistaking "cleaner cars" for real climate progress. We demand mobility, not just motors. Demand a Better Path: https://go.calbike.org/a/better-path-permanent-funding-e-bikes

Sometimes when I'm critical of what I put under the rubric of "Dem leadership" which includes but isn't limited to elected leadership, party officials, and big Dem organizations and donors, I get nitpicky nonsense of about whether specific constituencies are exempt.

This is one of the coolest visualizations I've seen of waves moving throughout the country over 2 years. Note the seasonal patterns in various states. From Yale school of public health

The Data Management Workbook: Practical Exercises for Better Organization, Storage and Use of Your Research Data by Kristin Briney. @kbriney.bsky.social.

Donald Trump deleted this from the government website. Let's be clear: there's funding available to cover SNAP benefits next month. Trump is stopping SNAP benefits because he wants to. He is forcing mommas and babies to go hungry.

So, a child was losing weight (the implication is the stress of the Alpha School's methods) so much so her pediatrician recommended additional snacks, and the School's untrained "guides" (who are not teachers) withheld those snacks from the child until "she met her learning metrics"?

NEW: The entire staff supporting ACIP was laid off, and most working groups haven't met in months. That means the US may not make routine vaccine recommendations for more than half of children in 2026, and it could halt new vaccines in the pipeline. My latest: www.theguardian.com/us-news/2025...

This is what the Democrats have been raising hell about.

I was thinking about this today & did some Googling: despite the fact that this spike is often blamed on children's Halloween behaviour (wearing dark costumes, not paying attention on roads, etc), ~40% of deaths on Halloween 2022 involved drunk drivers: www.trafficsafetymarketing.gov/safety-topic...

More of this, please. Also, for those of you who have been asking what the point of the #nokings protests is: among many other things, this is. It's no coincidence that this letter was published two days after seven million people got off their asses to protest against Trump. More Republicans […]

The Treasury Secretary declares himself to be pro-monarchy, and promises to punish the entire country if the people exercise their First Amendment rights.

Fustiliarian Friday: Trump/Kennedy/GOP use the shutdown as an excuse to destroy the CDC’s elite field epidemiology team and one of the most important epidemiology journals in the world. Gift link.

“ABC7 spoke to Pertissue Fisher, a woman who lives in the building. She said ICE agents took everyone in the building, including her, and asked questions later….’They was bringing the kids down, too, had them zip tied to each other.’” It can’t happen here, you say. But it is happening.

"Republicans run the entire government but can't keep it open" That's it. That's the whole story.

BREAKING: WE WON!!! 💥 💥 💥 Federal Judge William G. Young ruled today in our lawsuit against the Trump administration that the policy of arresting, detaining, & deporting noncitizen students & faculty members for their pro-Palestinian advocacy violates the 1st Amendment. Full ruling here:

He's telling us what he's doing. Using the military to suppress protest. At some point the opposition needs to listen to him and adjust strategy.

i don’t think he was supposed to post this. this is a company lobbying for medical cannabis, specifically for medicare coverage of it, and i think they made a whole commercial for an audience of one. “YOU will…” “cementing YOUR legacy,” millions will thank you… this was just for trump

It takes nine healthy, vigorous humans to keep 60 horses fed and exercised. Today, six of us are sick with COVID-19, influenza A, or both. Three were in bed or at the hospital this afternoon. It’s gnarly here in Ventucky. #COVIDisNotOver

This is a fantastic health breakthrough.

Imagine having access to the greatest information-gathering systems to have ever existed, and destroying them and replacing them with Facebook memes.

Why your next car should be an electric cargo bike

In addition to scraping your uploads for "generative AI" training, Academia dot edu is going to start claiming rights to your personal info— *including your signature & voice*— for anything they see fit. So now'd be a good time to remove all of your uploaded works, & then delete your whole account.

tldr humanity needs to engineer buildings around filtered air replacement rate and it's not even that dramatic but for dramatic results

RFK Jr now claiming, without evidence, that Tylenol during pregnancy causes autism. He has no qualifications to make these claims. He’s a menace who’s persecuting autistics while undermining public health and putting millions of lives at risk. He must resign.

WARNER: Do you accept the fact that 1 million Americans died from covid? RFK Jr: I don't know how many died W: You're the secretary of health and human services. You don't have any idea how many Americans died from covid? RFK Jr: I don't think anybody knows that W: How can you be that ignorant?

If you had told me in 2012 that Mitt Romney’s presidential campaign manager would be posting like this 13 years later i would not have believed you

A state could say: Congress apportioned $2 billion to us in the following bills… But the Trump administration hasn’t paid. So we are collecting it from federal taxes of state employees. Am I just making it up? Yes. But I want to see people try things.

Federal agents showed up northeast of Lake Cushman to check identification of crew members fighting Washington's largest active wildfire.

Full resignation letter from Demetre C. Daskalakis, a CDC leader, does not hold back. "The recent shooting at CDC is not why I am resigning. My grandfather, who I am named after, stood up to fascist forces in Greece and lost his life doing so. I am resigning to make him and his legacy proud."

Explaining this: As a presidential nominee who was confirmed by the Senate, Trump has to fire her, and her lawyers say that has not happened yet, so she is still in office.

There can’t be any gun restrictions because we have to protect against federal government tyranny, and if kids get shot we just have to live with it. Also the President can send troops to cities because the federal government can do whatever it wants. These two ideas are consistent and reasonable.

It's not "skepticism" when his stated goal has been to destroy not just mass vaccination but the entire public health infrastructure in the United States
