Hi all, I'll try to check in more often. Always looking for:

1) paid job/research opportunities to share with undergrads
2) cool ecophys/ecology stuff
3) connections for research & collaboration

I'm also reachable by my professional email, which is on my webpage: maryheskel.com

Important education message: "independent research has made clear that technology rarely boosts learning in schools—and often impairs it."

Ed tech is profitable. It is also mostly useless

Independent research identifies few learning gains

This morning, federal agents staged at the Powderhorn Park Recreation Center lot and began to throw chemical irritants at observers. They also kidnapped an observer. Our parks are meant for our children, youth, and neighbors. They should never be militarized zones meant to separate families. 1/

Last week in Minnesota, I watched ordinary people risk their lives to protect their neighbors. In the process, they not only won a significant—though not final—victory against authoritarianism, they proved virtually every MAGA social theory wrong. (gift link) www.theatlantic.com/ideas/2026/0...

Every social theory undergirding Trumpism has been broken on the steel of Minnesotan resolve. The multiracial community in Minneapolis was supposed to shatter. It did not. It held until Bovino was forced out of the Twin Cities with his long coat between his legs.

The secret fear of the morally depraved is that virtue is actually common, and that they’re the ones who are alone. In Minnesota, all of the ideological cornerstones of MAGA have been proved false at once. Minnesotans, not the armed thugs of ICE and the Border Patrol, are brave. Minnesotans have shown that their community is socially cohesive—because of its diversity and not in spite of it. Minnesotans have found and loved one another in a world atomized by social media, where empty men have tried to fill their lonely soul with lies about their own inherent superiority. Minnesotans have preserved everything worthwhile about “Western civilization,” while armed brutes try to tear it down by force.

The majority of organizing happening in Minnesota isn’t just peaceful, it’s INVISIBLE. Moms showing up who won’t be interviewed on TV, people whose ICE patrols don’t turn into viral video. The grocery runs, the donations, the people filming bc they happen to be there. Please remember this.

They are literally abducting people from their cars.

This is at the same Speedway gas station in St. Paul, MN, where they dragged a man off like a sack of potatoes.

Look at the brutality and violence they are using here.

The USDA's shutdown messages are increasingly unhinged. I discovered this looking up lecture materials & the banner blamed the "Radical Left Democrats". Today's is much worse.
