An obvious AI-generated ad included in a NYT email to me (a subscriber). So many questions: 1. Why only 23? 2. How is riding that thing easier (or safer) than just walking up the stairs? 3. Can that thing even drive up stairs, because it looks stuck. 4. WTF?
An AI generated ad for a stupid stair-climbing device that is completely pointless.

Today I got to take a ride in the ferry wheelhouse on my way home to Dartmouth! The oldest saltwater ferry in North America, it's "the best office view in Halifax," Captain Stuart said. And it sure beats sitting in bridge traffic. Thank you!

After the hard work and advocacy of the community, the Minister of Municipal Affairs has decided not to overturn the bylaw restricting infilling in Dartmouth Cove. We will look at their amendments closely, but at least for now, Dartmouth Cove won't be turned into a dump.

Maybe this @johncullenocean.bsky.social et al. piece where they said — "adding iron to the ocean is not an effective way to fight climate change, and we don't need further research to establish that" — wasn't straightforward enough because this idea just won't die. 🤷🏻‍♂️ www.nature.com/articles/461...

@altagliabue.bsky.social making a presentation at @ucl.ac.uk telling us that ocean iron fertilization won’t do jack for climate and will further harm fisheries. Yet, it’s the marine CO₂ removal (mCDR) method that has sold the most credits so far. 🤷🏻‍♂️
Conclusions from Al’s presentation:

• Iron limitation will not make a significant contribution to ocean carbon dioxide removal, even if tech challenges to scalability are dealt with
• ~4 years of emissions assuming the most optimal (impossible to achieve)
scenario
• The similarity of the 'fingerprint' of OlF on ocean biogeochemistry to climate change will make MRV very difficult
• Negative impacts on fisheries will compound climate effects and may emerge after 15-20 years after initiation of OlF
• Hampering our ability to reverse course or cease 🌊

this is a letter to the editor from a high school track runner who came in second to a trans girl in a race. her state house rep in maine started talking about it. so she wrote this: www.pressherald.com/2025/05/14/r...
Rep. Laurel Libby, R-Auburn, recently used my second-place finish in the 1,600-meter run, and that of my teammate in the 800-meter run, to malign Soren Stark-Chessa, the trans-identified athlete who finished first.

One of the reasons I chose to run cross-country and track is the community: Teammates cheering each other on, athletes from different schools coming together, and the fact that personal improvement is valued as much as, if not more than, the place we finish.

Last Friday, I ran the fastest 1,600-meter race I have ever run in middle school or high school track and earned varsity status by my school’s standards. I am extremely proud of the effort I put into the race and the time that I achieved. The fact that someone else finished in front of me didn’t diminish the happiness I felt after finishing that race. I don’t feel like first place was taken from me. Instead, I feel like a happy day was turned ugly by a bully who is using children to make political points.

We are all just kids trying to make our way through high school. Participating in sports is the highlight of high school for some kids. No one was harmed by Soren’s participation in the girls’ track meet, but we are all harmed by the hateful rhetoric of bullies, like Rep. Libby, who want to take sports away from some kids just because of who they are.
