Uploaded a Census handout in Grammarly to see who’d pop up in their Expert Reviews and looks like @shcohen.bsky.social and @albertocairo.com are among their AI experts. I have a feeling that’s news to them! www.platformer.news/grammarly-ex...

Emily is the best sports data journalist working right now, and I have no doubt she will continue to do incredible things in whichever newsroom is lucky enough to hire her. I’ll deeply miss getting to work with such an amazing colleague (and fellow FPL fan!!!)

U.S. vaccination rates are plunging. Look up where your school stands. Take a look to see what the kindergarten measles vaccination rates are in your area.

EXCLUSIVE: @laurenweberhp.bsky.social & I have spent the last year collecting school+county-level vaccination data from across the US and found that only about 28% of counties now have herd immunity for kindergartners from measles—that leaves about 5.2mn kids unprotected.

In deadly D.C. plane crash, city lights may have played a role. See how. The Post examined the bright skyline around Reagan National Airport and whether it may have been a factor in the January accident, which killed 67 people.

For our new visual investigation into how night vision and city lights may have played a part in the DCA crash we flew a drone along the helicopters route, filmed incoming planes through night vision goggles, and analyzed it all within a 3D model of Washington, D.C.

The deadliest roads in America The number of pedestrians killed by vehicles has increased in the U.S., with road infrastructure and inadequate safety measures among key contributing factors.

Wide roads and fast-moving vehicles — especially when combined with signs of poverty, homelessness, drug & alcohol abuse, plus a lack of pedestrian-focused roadway improvements — has produced a pattern of death-by-vehicle that is uniquely American.

Trump defends Saudi crown prince over Khashoggi killing The de facto Saudi ruler was branded a pariah in 2018 after the killing of Washington Post columnist Jamal Khashoggi. Now, U.S.-Saudi relations are approaching a high point.

You can oversee the bloody dismemberment of a Washington Post journalist with a bone saw, and the president of the United States will smile, shake your hand and threaten to pull the license of a news outlet whose reporter asks you a question about it.

There's an unsettling shift in cancer diagnoses in America, with rates for young adults in their 20s, 30s and 40s trending up even as overall cancer rates decline — and with geography appearing to be a key characteristic in who falls ill young. wapo.st/43HHrXZ

Parlays have become incredibly popular, with many betting apps encouraging these high-stakes multi-leg bets. But as legs are added, the chance of winning drops faster than the growth of the potential payout - which means sportsbooks have the advantage. Explore the math and and try your own bets:

ICE Is Deporting People to Africa on Nearly Un-Trackable Military Flights Immigration and Customs Enforcement (ICE) is deporting people to African countries like Ghana on military flights that are nearly un-trackable.

NEW: Air Force jets are doing ICE flights to Africa with transponders turned off, making them nearly un-trackable.

This includes the third-country removal to Ghana and another secret flight. We figured out where it landed.

We analyzed open source ADS-B data which leaves out countless other military aircraft that fly over D.C with their transponders off for reasons of "national security." Still, with the data we had available we could drill down into which neighborhoods are seeing the most change.

In Trump’s D.C. surge, helicopters hovered and surveilled day and night Park Police helicopters circled more often than they did in the same time period last year and at lower altitudes than other law enforcement helicopters in D.C. this August.

During Trump's federal law enforcement surge in DC, Park Police helicopters spent nearly 20 hours hovering over city neighborhoods, up from 3 hours this same time last year -- and flew hundreds of feet lower than other helicopters.

Washington’s Metropolitan Police Department’s officer count alone already puts D.C. ahead of any other large city in the United States per capita. Including the additional federal officials means there’s currently one officer for every 100 residents in D.C. www.washingtonpost.com/dc-md-va/202...
