Call for abstracts: I’m putting together an edited book on archaeology and horror. Details below. Contact me for full CFP or to discuss potential submissions. 🏺👻🧟🏛️

Fantastic news. More countries should do the same.

Wait. Elon Musk now has the email for every federal employee? Isn't THAT a bigger story than the stupid request for 5 bullet points of what they've been doing?

France's Nazis officially find CPAC too Nazi to attend. www.politico.eu/article/fran...

It's been pointed out already, but looking at current media coverage, apparently not often enough: trowelandpen.com/2025/01/22/c...

I've never understood how scientists, in particular, could flee from that Musk place only to take refuge in, wait for it, a Bannon place like #BlueSky. 🤦‍♂️ "On social media, Mastodon is managed and run by the community (e.g., https://neuromatch.social is a server run by neuroscientists) […]

What a fabulous collection & what a resource for understanding landscapes!

Welcome to the new Bluesky account for the Contemporary Archaeology module run by the Department of Archaeology, Durham University. This is a course where we explore the archaeology of the contemporary world in a hands-on way.

Minister Mona Keijzer negeert het vogelvriendelijke plan om neststenen in te metselen bij nieuwbouw en renovaties. Zelfs na de aangenomen kamermotie en de ruim 37.000 keer getekende petitie. Onbegrijpelijk!

"Trump Wants a Monarchy, Not a Presidency. He Must Be Stopped" Writing for Zeteo, constitutional law professor @kimwehle.bsky.social says we are in danger of losing our democracy over the president's false claim to unlimited executive power under Article II. Read/share: zeteo.com/p/trump-mona...

I just found out that my first book 📗, LAB GIRL 🌱🌿🌳, was challenged by a parent and subsequently removed from the shelves of the library at Walworth High School in Elkhorn, Wisconsin. So I decided to write a 🧵 on book 📚 #censorship 🚫 in American 🇺🇸 schools 🚸 1/n

This is really a great tutorial on plotting charts and how people can lie with data visualisations

Finally! I will defend my dissertation: "Relating Roman Rings. An interdisciplinary study using archaeology, data science and tree rings to understand timber provision in the German Provinces of the Roman Empire" at the VU in Amsterdam on May 26 at 15:45

Many #researchintegrity sleuths are volunteers with little financial support for their often-daunting work to uncover #scientificfraud. One of the most prominent, Elisabeth Bik, has now provided money to change that. @elisabethbik.bsky.social @science.org www.science.org/content/arti...

Tesla, whose chief executive, Elon Musk, has been advising President Trump on how to cut government spending, is likely to receive a lucrative contract to supply armored versions of its Cybertruck pickup to the State Department, according to public documents.

This enormous steel sculpture stands near the site of Croy Hill Roman fort on the Antonine Wall. Created by Svetlana Kondakova and Big Red Blacksmiths, it has been christened 'Silvanus', named after the Roman god associated with countryside and woodland. #RomanFortThursday

In landscape ecology, I emphasize how simple models can illustrate complex patterns—like how dispersal on an environmental gradient can look like species sorting and niche partitioning. So, I make toy models for class.

Ah, Lads! My heart is breaking. Just 78 Irish head-the-balls signed in the last hour. Please share this EU petition to ban harmful gay conversion therapy! Stand up for human rights!

I'm starting to see stories from Trump voters saying "This isn't what we voted for." No. It's exactly what you voted for.

I honestly wonder when @wikipedia and @wikidata go offline. I understood their servers are running on USA soil, and surely both contains plenty of content that violates USA law (under the new admin). This is a very significant risk to projects like @wdscholia and many, many more What is the […]

Sámi archaeology for #SamiNationalDay Trees were seen by the Sámi as mediators between people and deities, and were likely engraved with crosses whilst offerings were made. Intensive forestry is destroying culturally modified trees at an alarming rate. 🆓 https://doi.org/10.15184/aqy.2024.184

Elon Musk believes in the "checks" part of "checks and balances" so long as the checks are written to him.

Er is al veel gewaarschuwd voor de mogelijke gevaren van AI, maar dat een stelletje geradicaliseerde tech-bro’s de regering zouden proberen over te nemen hoorde geloof ik niet tot de scenario’s.

Nu de regering-Trump hard ingrijpt in de wetenschap als die volgens politici de verkeerde woorden gebruikt, en nu het duidelijk is dat grote Amerikaanse bedrijven door de knieën gaan en het nieuwe regime steunen, wordt het belangrijk om keuzes te maken. neerlandistiek.nl/2025/02/waar...

🚨BREAKING. From a program officer at the National Science Foundation, a list of keywords that can cause a grant to be pulled. I will be sharing screenshots of these keywords along with a decision tree. Please share widely. This is a crisis for academic freedom & science.

On May 10, 1933, Nazis burned the library of The Institute for Sexual Science. The Institute was founded by Dr. Magnus Hirschfeld. Its community clinic pioneered healthcare for queer, trans, & intersex people. The Institute was targeted & attacked as part of a Nazi government censorship program.

The universe speaks in mysterious ways.

Book burning? If everything was digital in Hitler's 1930s Germany, this is what his book burning would have looked like: deletion of data, removal of websites, retraction of scientific studies, censorship of words like "equity," "diversity," "climate change."

Science is political. It wouldn't necessarily have to be partisan. But when one party is opposed to science-based policy, scientists have a choice between saying "you're right, thoughts and prayers are probably as effective as reducing carbon emissions" or saying "fuck that."

Every archaeologist in the US needs to be proactively organizing against the erasure of cultural heritage 🏺

Reading through the first ten days of executive orders--not even all of them, just some--is like sitting through a vile lecture, unable to respond. And then seeing the USDA climate-change related pages pulled down. And then funds for cross-border education pulled... on and on. By contrast, this:

Dear California farmers and Congressional representatives: Trump has just literally thrown millions of gallons of #water away that farmers were counting on this summer, purely to brag that he could. That #cawater cannot be captured or used now by anyone. www.latimes.com/environment/...

Legacy media helped create this anti-trans moment. Now they’re reporting on it. ▫️Legacy media in US [& UK & Ireland] have engaged in a campaign of vilification against trans ppl, unprecedented since the AIDs panic & 1930s antisemitism. objectivejournalism.org/2025/01/lega...
