One individual briefed on the negotiations told POLITICO there has been so little back and forth on core economic issues, such as wages, that they believe a strike appears increasingly inevitable.

Would be interesting (sobering) to see both how economic opportunities affect these decisions (e.g., are lower income/wealth folks forced to keep their heads down more but higher SES folks able to organize or move more?) and how these decisions change future economic successes
New research confirms what many of us see: there's a large internal migration of LGBTQ people in the US, especially trans people, to friendlier states & cities.
Since 11/2024, 9% of all trans people have moved to another state, 43% have considered moving.

If public health and vaccines still exist when the next pandemic happens, some important lessons to save lives and prevent illness:
A study on 1.7 million people in Hong Kong shows superior hybrid immunity to Covid in people who got vaccinated before infection vs. people who got infected first. "Our findings are a direct rebuttal to arguments for natural immunity," the authors write. doi.org/10.1016/j.va...

In a study following 23 million people age 18-59 (pretty young) for 4 years…despite the fact that the ones who got the COVID vaccine were overall older and sicker at baseline, they not only had 74% lower risk of dying from COVID than the unvaccinated but 25% lower risk of dying from any other cause!

Compensations, eg slowing movement time in order to maintain safe driving and task accuracy. That's a good thing!
