Spoke with a PI whose postdoc is trapped abroad because of social media vetting. It appears the postdoc missed disclosing one account and it's unclear if they can come back… ever.

This is the country we live in now.

It was just a matter of time…

Long exposure photo of students sitting on the beach, facing the water and watching an olive ridley nest just after midnight.

Long exposure photo of an olive ridley returning to the water after nesting.

Students take turns digging up the nest to relocate the olive ridley eggs. We worked with red light, but the sky looks lighter due to a long exposure shot.

The group gathers for a photo in front of a strangler fig in Copalita National Park, Mexico.

We finally saw an olive ridley nesting last night! I used the long exposure setting to take photos under the full moon.

Today, we went to Copalita National Park before heading to the beach.

Two students rebury Pacific green turtle nests in a hatchery.

A student poses next to a leatherback track. It was a false crawl: she didn’t lay.

Students out plant cactus.

Neat triangulation.

The learning continues. Night time nest relocation, a leatherback track after we saw the female false crawl, revegetation, and triangulation.

Students sit in a half circle as a cooperative member tells his story and our local coordinator translates.

A student has found a nest of turtles emerging and gets ready to place them in her bucket.

Two student students tip their buckets with hatchlings toward the camera.

A student has emptied her bucket near the water’s edge.

Yesterday afternoon, we learned about the history of sea turtle conservation from local cooperative members as well as government employees. This morning, we rescued hatchlings on the beach.

Students watch a nest of olive ridley hatchlings emerge under red light.

Students line up to move turtles during the tank cleaning.

A student walks among stones in the tank with a turtle in her hands. Other students scrub the tank with scrubby sponges under their feet.

Two student students prepare a turtle for a vitamin injection.

We saw our first olive ridley hatchlings last night. This morning, we cleaned a large tank and helped handle green turtles for vitamin injections at Centro Mexicano de la Tortuga.

Carved jaguar was a symbol of the nobility.

Before heading to the coast this afternoon, we toured Monte Albán to learn about some Mesoamerican archaeological history.

Two blue painted cats sit on either side of a shop entrance flanked by green walls.

Squash soup for dinner.

I have the privilege of taking students to Mexico for just over a week for my Sea Turtle Biology and Conservation Course this semester. Despite the travel complications yesterday, all but one arrived to Oaxaca. Some scenes from the city.

NSF building on Eisenhower Av. HUD now owns.

Destroying the NSF mural in the foyer. Of the Eisenhower building.

The National Science Foundation sign on our Eisenhower Av building is now gone.

The NSF mural in the foyer is removed and torn off in sheets.

We were supposed to celebrate the 75th anniversary of the agency in May 2025. That never happened.

I would be inclined to go for a) with an appreciative but honest tone.

The university mandated everyone to come back to the office but now say they can longer afford to keep paying for office phones.

On the list:

Intergovernmental Panel on Climate Change;

Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services

International Tropical Timber Institute

Internacional Union for the Conservancy of Nature

Inter-American Institute for Global Change Research

Maybe this is my sign to tone down my perfectionism this year.

I can tell you are tired because the alt text mentions craps on tote bags.

Trump administration cannot slash NIH research funding, court rules District Judge Angel Kelley last year blocked the cuts, and on Monday the appeals court agreed.

The district court injunction that prevented NIH from capping indirects at 15% was upheld today on appeal!

7/ Here's the bottom line: This is an unprecedented shift that risks weakening protection against preventable diseases at a time when outbreaks are rising and children are already being hospitalized. Vaccines don’t work without strong supporting systems...and the U.S. doesn’t have Denmark’s.

I felt that way, too.

What about Connor, Conrad, Conley, Colin, or Cedric?

I am on a C kick.

As parents are helping their kids consider colleges, this is my perennial reminder that state schools often have lower price tags, yes, but private schools, including many small liberal arts schools, often have better aid packages, and are thus often cheaper in the end (but may be more competitive).

Every article about the dismantling of NCAR says the same thing, but read every one because it's so insane.

Ha, I love this thread. I have learned the students refer to the courses as Bio 1 and Bio 2, but the faculty call them 2010 and 2011.

A model human skeleton is posed in a window with one arm resting on the sill and its chin resting on its other hand. It looks like it is enjoying people-watching everyone passing by.

I really appreciate whoever keeps posing the skeleton model in the anatomy lab room like this; I grin every time I walk past it.

That is amazing!

Grilled cheese.

It was our first publication with @stacksjournal.bsky.social, and I highly encourage others to consider this affordable, open-access journal with an innovative peer review process.

This knowledge is important in diet reconstructions using stable isotope methods, especially for animals that consume prey whole, as studies often use non-invasively collected tissues as a proxy for the whole animal.

Parts of a whole: isotopic difference between single keratin-based tissues and whole-body tissues of birds and mammals - Stacks Journal Peer-reviewed research - Parts of a whole: isotopic difference between single keratin-based tissues and whole-body tissues of birds and mammals

New OA pub in @stacksjournal.bsky.social : @zoologistkate.bsky.social social compared the isotopic composition of hair and feathers to the whole body of mammals and birds. It turns out these tissues can sometimes (but not always) represent the whole body.

Selfie of me just after running 13.1 miles with a finish line in the background.

I ran a slow half marathon this morning…it was 75F by the end. This afternoon, I did some grocery shopping and made a double batch of enchiladas to take a pan to our neighbors with a newborn. #WorkfreeWeekend

it's wild that R, the ubiquitous statistical computing language, was co-created by a Māori prof (Ross Ihaka) — and yet the vast majority of scientists who use R don't know

this is like inventing the toaster. possibly the largest impact of a single member of an indigenous community on modern science
