Saturday's Weather Rating: 10/10 🥳🎉THE FIRST PERFECT DAY OF 2026!!! High temperatures reach the upper 70s with comfortable dew points, sunny skies and a southerly breeze. That's the secret formula, man. The vibes are immaculate out there!!

This is an excellent deep dive on a terribly hard and heartbreaking problem. Proud of the brilliant @sonalirajan.bsky.social, whose vital work is featured in this piece. She and others in this field work tirelessly to make a seemingly intractable problem incrementally tractable.

Child: I know your name. Mamdani. Obama: What’s his first name? Child: Mayor.

The Artemis II crew proposed naming a moon crater after Commander Reid Wiseman’s late wife Carroll, who lost her life to cancer 😭

The call for abstracts for this year's National Research Conference for the Prevention of Firearm-Related Harms is now open! Threading all the key details below! (1/n) --

Iconic that NASA woke up the #Artemis II crew with Pink Pony Club

What a grift from Haidt. Book 1: parents, it’s not your fault, it’s the phones Book 2: parents, it’s not your fault for being busy, in fact that’s better for your kids.

Wow @tressiemcphd.bsky.social. It's not just the physical violence, it's also the data surveillance apparatus--data we voluntarily and involuntarily share, weaponized by the state. "It is important enough that a federal cowboy kept one hand on his phone even as his other hand reached for his gun."

Friends, we have been so happy to see the excitement and interest in our Inaugural RFP! To provide support for potential applicants, the wonderful Meg O'Toole and I will be hosting an optional webinar tomorrow (Feb 2nd) at 12:00PM ET. Link to register is here! lnkd.in/e8QvjJ8r

Hello Mayor @zohrankmamdani.bsky.social ! I encourage you to ignore any advisor recommending remote schooling instead of a snow day if a storm hits. Kids will learn much more playing outside (or in!) with friends and family than they will doing digital worksheets. Keep up the good work!

have lived every bit of this with my fellow scientists, but seeing the destruction of our nation’s research infrastructure all bundled into one piece like this made me weep: www.nature.com/immersive/d4...

SCOTT JENNINGS: "Let's not get our knickers in a twist here." LEIGH McGOWAN (PoliticsGirl): "Why are you talking like that? It's insane. Your attitude is just horrifying…" [I love her. bsky.app/profile/poli... ]

Thanks so much to @danimcclain.bsky.social for this powerful, heartbreaking piece and for highlighting some of the work I have been fortunate to do with my wonderful collaborators at BU on the staggering disparities in exposure to firearm violence that Black children face in this country --

This is a genuinely good (shockingly rare!) use of an LLM. A tool that scrapes news articles to build a detailed, live, and human-verified database of gun violence across the US. The resulting database can then can be used to better research and stop our violent epidemic.

Oh gosh -- so grateful for our field and for people like @robincogan.bsky.social who continue to devote so much to ensuring our kids are safe and cared for 💖

I'm so proud to share that ​our @everytown.bsky.social research team launched an Inaugural RFP today for a new seed grant program. All details on how to apply/deadlines/eligibility are included in the link below. Please share widely friends and thank you! shorturl.at/sESve

Super proud of my brilliant and thoughtful @everytown.bsky.social team for launching our Gun Law Rankings today! everytownresearch.org/rankings/ Policies matter. Leadership matters. Take a look through our tool below -- grateful to have so many wonderful colleagues dedicated to this work.

Made a quick primer re: calling our reps - see below and please share if helpful❤️ So grateful to every person showing up in all ways big and small - on hard days with difficult news, it gives me a lot of hope to know how many good people there are showing up for and taking care of each other. (1/3)

Zohran Mamdani was officially sworn in as the 112th Mayor of New York City by Attorney General Letitia James with his hand on the Quran. Happy New Year! 🎉

I want to talk briefly about the implications of using AI in creative work. First of all, we agree so-called "AI" is ruining our society and planet. BUT (yikes right?), AI is also transforming our cognitive relationship to the things we use it for. 1/12

Congratulations to @rsbeidas.bsky.social and her team for winning the $5000 Greenwald Award for research on firearm violence prevention for their paper, "Implementation of a Secure Firearm Storage Program in Pediatric Primary Care: A Cluster Randomized Trial"! static1.squarespace.com/static/63924...

The very very best - so grateful for these few days in AZ with our brilliant and thoughtful and dedicated research community (and so many of my favorite people)! 💖 #2025firearmresearchconf

The trauma we inflict on children in this country is unconscionable.

Thank you to my friend & colleague Amy E. Dark DNP, MSN-PH, BA, RN for sharing the article featured in my most recent blog post! @sonalirajan.bsky.social thank you & your colleagues for all you do to support the safety of our nation's children & teens. relentlessschoolnurse.com/2025/11/17/t...

I am just so incredibly proud of this conference and of our Society and, of course, our field. Cannot wait to see so many friends/colleagues next week in AZ -- www.firearmresearchsociety.org

@everytown.bsky.social @sonalirajan.bsky.social @meganranney.bsky.social @bradyunited.org

Truly - for some joyful/fun internet content - join @snowdaylearninglab.org, @haenyyoon.bsky.social, and @lmv.bsky.social (my best buds and favorite people in the entire world) tonight!👇

Constantly in awe of my incredible friend @abbeyclements.bsky.social for her brilliance and kindness and leadership and for all the ways she shows up -- every single day -- for our teachers and kids and schools. @teachersunify.bsky.social www.chalkbeat.org/philadelphia...

“What we should be calling for is for our elected officials to use the tools that we know work to render these drills obsolete…. The burdens we are putting on our schools & our kids to prepare for the potential of this kind of violence is, frankly, unacceptable.” — @sonalirajan.bsky.social 🛟

@sonalirajan.bsky.social sharing the compelling opinion piece you co-authored, recently published in @amjpublichealth.bsky.social via this blog post: relentlessschoolnurse.com/2025/11/09/t...

The discourse on active shooter drills, particularly in K-12 schools, is complex. Thank you to Time for this piece, for referencing our recent NASEM consensus study findings, and for including myself and many of my wonderful colleagues in this reporting: time.com/7331491/less...

Sharing our latest paper -- now out in AJPM Focus on the risk of child firearm assault during afterschool hours. This new work was led by the brilliant team at BU and also includes one of my wonderful doctoral students as a co-author as well -- www.ajpmfocus.org/article/S277...

Thanks so much to @thetrace.org for their critical reporting. And for including me (and some of my favorite colleagues!) in this piece on active shooter drills: www.thetrace.org/2025/10/scho... @everytown.bsky.social @columbiauniversity.bsky.social @teacherscollege.bsky.social

Grateful for the opportunity to have been on an episode of the "Measure of Everyday Life" discussing our recent NASEM consensus study (including, what this work entailed and our recommendations/takeaways for K-12 schools across the nation): measureradio.libsyn.com/protecting-o...

a few of my favorites from #nokings in nyc yesterday! love our city so much - grateful to every person who showed up here and across the country!

ZERO arrests in NYC. #NoKings

I feel so lucky to be working and collaborating with such a thoughtful and dedicated team @everytown.bsky.social. Our latest -- a new report on arming teachers -- out this morning: everytownsupportfund.org/press/new-ev... @teacherscollege.bsky.social @teachersunify.bsky.social

NYC just spectacular this week✨💖

So proud of our latest piece, now out in AJPH and co-authored with some of my favorite people: ajph.aphapublications.org/doi/10.2105/...

What's happening in Chicago is not normal. The arrest of Alderperson Fuentes is just the latest example of how far Noem and Bovino are willing to go to ignore the rule of law. We must all speak up.

We're just a few weeks (!) out from this year's National Research Conference for the Prevention of Firearm-Related Harms - I cannot wait to see so many colleagues/friends in AZ as we bring our research field together to collectively advance critical solutions for gun violence prevention --

So proud of my @everytown.bsky.social research team for releasing a new report today on domestic firearm homicide-suicides (and for @19thnews.org for powerful coverage of this difficult and needed work): 19thnews.org/2025/10/fire...

Looking forward to joining our colleagues at Brady, Giffords, and the Community Justice Action Fund at 12PM ET today to discuss the impacts of the Trump Administration’s policy and funding rollbacks on gun safety progress. Link to register/join is below -- giffords-org.zoom.us/webinar/regi...

i love ta-nehisi coates so much

Another Monday following a weekend of deadly and devastating shootings in this country. But the thing giving me hope are the many many people working so hard every single day across sectors and disciplines to prevent this violence. Grateful for every person in this work and in this fight.

What feels like forever ago, I made a starter pack of gun violence prevention activists. Today felt like a good day to dust it off again. Lots of folks out there doing really powerful work to keep all of us safe from guns. go.bsky.app/QYwdBGk

“We are currently governed by a leader indifferent to scientific consensus if it contradicts his political or economic interests, hostile to immigrants and intent on crippling the research universities that embody our collective hope for the future. The menace now is within.”

One of the many things I’m doing today is sending postcards to my lawmakers about how critical the CDC Injury Center is to the health of our nation. It must be protected & funded. You can support this effort by calling, emailing, posting. keepamericasafe.info/events

Endlessly proud of our research field and of our Society especially (also - registration for our annual conference is open)! I can’t wait to see so many friends/colleagues from across the nation in AZ this November:

RFK Jr. went on Fox News today to claim that HHS has had “no successes” in the past 40 years. I beg to differ. Figure from Lei et al., NEJM 2020. Link below.
