And Madonna's version of Santa Baby was also adjacent to all of this stuff.

Andy Rivkin @asrivkin.bsky.social · 5h

Having lived through it, I think that a good fraction of it was "Madonna in a(nother) movie", plus Madonna and Warren Beatty were either actually an item or just rumored to be one at the time.

I stand for the National Anthem, I enthusiastically stand for Take Me Out to the Ballgame, and friends I've been to games with know that for several years now, if I stand for GBA I do it for their benefit and only after grousing about it.

God Bless America is just a song by Irving Berlin. It’s not the national anthem. America is so far down the moron hole it will never get out

Chicago, because Bud Selig was such a terrible commissioner and made so many baseball fans so unhappy for so long, I don’t want him to be happy either.

Chicago priest Fr. Larry Dowling describes procession to ICE facility: “No one had the courage to speak directly to us. No one from Homeland Security could stand in the presence of the Monstrance holding the Blessed Sacrament. No wonder. Evil is repelled, recoils in the presence of Christ.”

FAREWELL TO BENNU by Danielle Rose Baker. A watercolor painting of asteroid Bennu, trailing debris from the left, with an abstract mottled background in navy, purples and blacks. The sun, spacecraft OSIRIS-REx and a distant Earth are seen on the right-hand side.

Well, congrats to the Tigers and their fans. They didn't let their end-of-year losing streak define their season, as tough a loss as this is.

And big, big congrats to the Mariners crew. Who do you want throwing out the Game 1 first pitch--Ichiro, Junior, or Edgar? Or King Felix, I guess?

Sure, you bunt with 1st and 2nd here, I don't hate that--the double play is in order. But man on 2nd and nobody out? The bunt is just throwing away an out.

Andy Rivkin @asrivkin.bsky.social · 2d

Did they actually just talk about Gleyber Torres "squeezing out number 2"‽ I mean, I know what they meant but damn.

Andy Rivkin @asrivkin.bsky.social · 2d

Totally agree--I remember enjoying the hell out of the 1991 Series, with 2016 coming in second. 1985 was great, too.

Just don't forget the spinades.

Planetary scientists - we have a continual lament that goes like, waaah we have too many meetings how can we work and put in so many abstracts! Here's a solution! Choose a different meeting!

Dr. Adeene Denton @spacewhalerider.com · 2d

It's really disheartening to try to talk to colleagues about boycotting a conference that removed all its records of abstracts pertaining to DEI, only for the response to largely be "I don't want to go, but..." But what??? Each of us has agency! You can choose not to go!

A two-post summary from April, though they also took down and scrubbed community meetings ("AGs" if that means anything to you) of content they deemed incompatible with the EOs issued at that time, and did all of this proactively without being asked.

In response to the Trump executive orders, the Lunar and Planetary Institute (#lpi) is removing abstracts from previously held meetings that used to be archived on their website.

Here is an example of one that was removed from the 2025 Lunar and Planetary Science Conference (#lpsc).
