Friday was my last day at WIRED. Today I started a new job at Bloomberg on a dream desk with @suryamattu.com and @jeffykao.bsky.social.

Got a tip? A dataset? Something we should look at? Find me on Signal at dmehro.89

In no particular order, here’s some stuff I’d like to continue to dig in to:

Good "missing data" story
When Trump encounters a demographic he doesn’t care for, he “disappears” them–in many cases, the very record of their existence.
Meet America’s new “missing persons," and the govt campaign to delete statistical evidence of anyone who doesn't fit Trump’s idea of our new golden age.

Opinion | Here are the people Trump doesn’t want to exist
Women, people of color and those in the LGBTQ+ community are main targets.

The story behind RFK Jr. in Samoa's measles crisis has never been reported. He wasn't there to spread misinformation about vaccines (though he did). He wanted to study a "natural experiment" of unvaccinated kids.

“I can’t imagine anything less ethical or more cruel.”
www.nbcnews.com/news/us-news...
Experts saw Samoa's plunging vaccination rates as a crisis. RFK Jr. saw an opportunity.
New details show how Robert F. Kennedy Jr., then chair of an anti-vaccine group and now Trump’s pick for health secretary, sought to exploit a deadly vaccine accident.
