And we’re up and running. First Antarctic cores have been CT scanned! The GCR has truly become a world-class core analysis facility!

The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku.

Looks like the Gulf Coast Repository @tamu.bsky.social is getting a new "toy" today.
So exciting, can't wait to see it up and running!

A tweet from BrooklynDad_Defiant! says: “THIS.” followed by several clapping emojis. The image text reads: “Let’s give teachers $50k signing bonuses, $100k salaries, and $60k student loan forgiveness. You know, the same as ICE gets.”

Delays and increased screenings for visas mean that many students didn't make it to campus on time – and that has some big implications for the economy.

Question for Mike Flood: With $450 million being allocated to Alligator Alcatraz, and ICE burning through $8.4 million a day to illegally detain people—How much does it cost for fascism? How much do the tax payers have to pay for a fascist country?

Austin is on the way out as TX most desirable city!

Many of the rich and famous are instead moving to Bryan, TX. Elizabeth Holmes moved first, and she has convinced other rich people like Ghislaine Maxwell to join her here.

Japan has managed a huge accomplishment: fully covering the offshore parts of their subduction zones, which generate massive earthquakes and tsunamis, with more than 200 fiber-connected geophysical stations -- at a cost of hundreds of millions of dollars.

Nothing else in the world can compare.
