Glad you brought this up - this Mexican is the first and only in this sport, and everyone was impressed by her determination - the USA gold medalists were so sweet, she removed her skis and hugged her dearly. The MSNBC cut out all of it. Why? That's the best of the #Olympics! empathy and love.

Treatment for preeclampsia. Would be huge if results hold up.
Researchers celebrate early results of a drug that may become the first treatment for a serious complication of pregnancy called preeclampsia. It's got the potential to save many lives.
It's a dangerous complication of pregnancy -- but a new drug holds promise

Impressive how much AI is (undeservely) trusted.
With actual disclaimers about errors in some chatbots' outputs, and all the cases of hallucinations already publicized, it took someone asking for a double check to uncover what amounts to AI-induced breaches of fiduciary duty, fraud...

Anyone who gets mad when a woman says "no, I'll not talk with you because you don't recognize me as a human being" should urgently go touch grass.
Here's an example of the reaction I'm describing here, and I appreciate something this particular poster makes clear: They neither understand nor respect boundaries. There's no policing happening here, just my own decisions about who I will have a conversation with.

A lot of people really don’t realize that there is a vast amount of information out there that is not online and plausibly never will be, or can’t be.
I think that's a point that will surprise a lot of people. There's a lot of calling the internet capable of accessing "the sum of all human knowledge" and such that I think gives people the impression that any and all records exist online somewhere.
