Black and white photo of Jesse Jackson, taken by Don Carl Stefan in 1972. It is a head and shoulders shot of Jackson, arms crossed and looking over his left shoulder and st something off frame to his left. 

Jackson here is a young, black man dressed in a dark, collared shirt, light vest. He has a medium-length Afro and a mustache. He is sporting a button that reads “Ingreso adecuado ahora” which means adequate income now.

Friends — did you know that Jesse Jackson was a speaker at the 1st National Conference on Minority Participation in Earth Sciences?

This 1972 USGS event sparked a lot of great work before R’s decided to shut it down. I was surprised when I learned of his participation-maybe you are too.

Once you notice society's base reluctance to refer to women as "geniuses" with the same frequency they do as men, no matter how talented or influential she may be, it's a thing you never really stop noticing.

ICE Begins Buying ‘Mega’ Warehouse Detention Centers Across US Plans for such centers and jails in nearly two dozen communities have sparked protests over suitability, proximity to homes and schools.

BIG news from @bloomberg.com, which confirms that ICE has gone ahead and *purchased* multiple commercial warehouses with the aim of converting them into mass detention camps.

This is likely to be the big detention story of 2026 — literal warehousing of people.

Also, may I say that I don’t agree with people saying ICE and CBP need “more training.” They’re doing exactly what this administration has trained them to—impose a reign of fear in blue cities. They don’t need more training. They need to be ripped up root and branch.

I am really excited to share news of this new jaw...until now Paranthropus had been conspicuously absent from the Afar.

Fieldwork at Mille-Logya is not easy, and this fossil is the result of years of very hard work (and a lot of days of dry screening by our team)!

Five Republicans joined with Senate Democrats today to take a step forward in checking President Trump's unlawful actions in Venezuela - but we need everyone to stand up and use your voice to demand the Senate assert our Constitutional authority over the use of military force.

THREAD: I'll fact-check all the viral misinformation about the US military operation in Venezuela in this thread

This image, purporting to show the US military arresting Venezuelan President Nicolas Maduro, is AI-generated.

This is a good visual. Looks like in order to ensure we have proof that we mailed something on a specific day, we will have to stand in line at the post office and request a manual post mark.

Open up this picture fully.

Then look at the surface of Mars.

Then look up to the top right.

Spot Mars' moon Phobos high in the sky.

Then notice the bright spot beside Phobos.

That's Earth.

Unbelievable. This would be a terrible blow to American science, writ large. It would decimate not only climate research, but also the kind of weather, wildfire, and disaster research that has underpinned half a century of progress in prediction, early warning, and increased resilience.

A deeply dangerous — and blatantly retaliatory action against Colorado — by the Trump administration.

NCAR is one of the most renowned scientific facilities in the WORLD — where scientists perform cutting-edge research everyday.

We will fight this reckless directive with every legal tool we have.

NSF pares down grant-review process, reducing influence of outside scientists Memo cites overburdened staff, but some say move also aims to elevate White House priorities

NSF now planning to let POs largely decide what gets funded, and to send PIs reviews that are only 3-5 sentences long. They don't have to use outside reviewers (except maybe 1) and don't have to convene panels. (1/5)
