President of MIT not mincing words today in @statnews.com www.statnews.com/2026/05/27/s...

So let me say it as clearly as I can: Without basic scientific research, supported by the kind of farsighted public investment that allows large-scale, undirected, curiosity-driven inquiry, the scientific pipeline will run dry.
In daily life, people may not feel the effects right away, or even in 10 years. But we will feel it. And when someone we love needs therapies that could have emerged but didn't or when other countries now
investing in science can launch new science-based industries or run their societies on vast resources of fusion energy or reap the benefits of quantum computing power or advanced medical breakthroughs, America will wish it sustained its leadership in scientific research here and now.
Sally Kornbluth is the president of MIT.

Cross-country skiing gold medalist Jessie Diggins: “I'm racing for an American people who stand for love, for acceptance, for compassion, honesty, and respect for others...For everyone out there caring for others, protecting their neighbors & meeting people with love, every single step is for you."

A photo of cross-country skiing gold medalist Jessie Diggins, who said in a social media post, that her motivation comes from the people she believes represent the country’s best values. She stressed that her focus is on compassion and inclusion.

“I'm racing for an American people who stand for love, for acceptance, for compassion, honesty, and respect for others. I do not stand for hate or violence or discrimination," she said. "I get to decide who I’m racing for every single day, and how I want to live up to my values. For everyone out there caring for others, protecting their neighbors and meeting people with love - every single step is for you."

Diggins concluded by saying, "You are the ones who make me proud to carry the flag, and I hope I can bring you joy over these next few weeks."

The recent days have been horrific. We can't become numb to repeated instances of illegal and unconstitutional action by government agencies. It's even worse when public officials are blatantly lying in ways that contradict dozens of pieces of video evidence.

The Seattle area runs 14% less bus service today than it did in 2019. The region grew by 3% in that time. We’ve got to get back to running more frequent transit. That’s going to take more investment from the City, State, & County. Great research from @urbaninstitute.bsky.social & @yonahfreemark.com
