nasw.org/2026ScienceinSociet… “Texas Banned Abortion. Then Sepsis Rates Soared,” won the 2026 @sciencewriters.org Science in Society Journalism Award! I'll be in Corvallis, Oregon this weekend at the Science Writers conference to accept the award! If you're going, give me a shout out!

This huge cable that’s a safety hazard has been lying across our front lawn since the storm hit NJ on the Fourth of July. @OptimumHelp refusing to send a crew to remove till 7/20 I fear for our safety does anyone know how to expedite the process?

Purely unscientific survey: If you are a NJ/NYC commuter, take the @NJTRANSIT regularly, or work in the Meadowlands, how do you plan to get to work during the World Cup? I’m especially interested in hearing from people who don’t have the option of working from home!

Sophie was my (much smarter) partner in a class I audited at MIT when she was in grad school. Kind to a much older student and talented as the day is long. I'm not surprised - now someone should snap her up!

3/ It’s hard to describe what this win means. This industry can be tough on POC and other minorities. It feels surreal to share this with Haru Coryne. We’re the kind of people I wish I saw winning awards growing up.

4/ I’m no longer at ProPublica and am looking for what’s next — open to journalism, data science, or research/consulting roles (NYC/hybrid/remote). prioritizing good management + fair pay. full series: ctmirror.org/series/on-the-h…

SO PROUD of @mpetitchou, an amazing data reporter, more importantly a wonderful person, for her @PulitzerPrizes win in local reporting about Connecticut’s towing laws favoring unscrupulous companies. Also named is former ProPublica reporter @Harucoryne 🎉 pulitzer.org/winners/dave-al…

So proud to be a @PulitzerPrizes winner along with my good friends Haru & @GinnyMonk. We all worked on this data together!
JUST IN: ProPublica and @CTMirror’s “On the Hook” series, which exposed how Connecticut laws had come to favor towing companies at the expense of low-income residents, has won the Pulitzer Prize for Local Reporting. It’s ProPublica’s ninth Pulitzer Prize.

The latest data story in our (now Pulitzer-winning) series, Life of Mother. Another stark sepsis finding in Texas
Under Texas’ abortion ban, the rate of sepsis shot up by more than 50% for women hospitalized when they lost a second-trimester pregnancy. Our new analysis shows the risk varies widely between the state’s two largest metro areas. propublica.org/article/texas…

NEW STORY from me + superstar team @asuozzo @lizziepresser @Ksurana6 <3
Pregnancy became far more dangerous in Texas after the state banned abortion, according to ProPublica’s first-of-its-kind analysis, which found the sepsis rate for women hospitalized as they miscarried in the 2nd trimester shot up by more than 50%. propublica.org/article/texas…
