In collaboration with Nature, I investigated the impact of the Trump administration on US science one year after its return to office. More than 7800 research grants were cancelled or frozen, affecting ~25000 scientists and research staff and resulting in an ~US$32 billion in lost research funding.

Wonderful to have a Svelte meetup in Berlin! Thanks to @fubits.dev and @peterkogo.bsky.social for organising it, and to @dominikg.dev for coming over. Thanks also to all three of you for presenting! It was a great start, and hopefully there will be many more to come!

The risk of an #AMOC shutdown - explained in 15 minutes at the Arctic Circle in Reykjavik on Saturday. I had the honor of presenting a letter by 44 experts warning of that underestimated risk to the Icelandic 🇮🇸 climate minister Guðlaugur Þór Þórðarson. youtu.be/k0FUZKQhU6U?...

Data visualizations are some of the most powerful tools in a climate science communicator’s playbook. However, designing visuals that are clear to the public and policy makers is not a straightforward task, writes @rachitdubey.bsky.social . So, what works?

People tell me nobody wants to look at climate curves anymore, yet here we are!!! Please enjoy our interactive journey through 485 million years of climate history and dive into the fascinating and important work of paleoclimate scientists. 🎁 www.zeit.de/wissen/umwel...

Last week I had the pleasure of finally releasing the #SveltePlot alpha version during my talk at the #SvelteSummit in Barcelona. It's a new visualization framework for @svelte.dev that I've been working on for the past 18 months, so it's about time for a 🧵

stoked for svelteplot.dev, launched on stage just now at #sveltesummit by @driven-by-data.net

On the anniversary of the sinking of the Titanic, we thought we'd answer a question that's often asked, "If they raised the Mary Rose, why not raise the Titanic?" Allow our scaled diagram to explain...

I'm very pleased to share Tunnel & Fortress, a new live coached training series bringing the art of system administration to those with no prior experience in the field. Participants will deploy, garden & harden servers to keep their communities safe. video.nikau.io/w/sXj2kQ8vQo... #exitbigtech

The Wikimedia Foundation, which owns Wikipedia, says its bandwidth costs have gone up 50% since Jan 2024 — a rise they attribute to AI crawlers. AI companies are killing the open web by stealing visitors from the sources of information and making them pay for the privilege

I’m thrilled to bring together two institutions that shaped my work: BarabásiLab & metaLAB (at) Harvard. On June 11–12, 2025, we’re hosting Data | Art—a conference on how data entangles with artistic, scientific & curatorial practices. We have a stellar lineup of speakers! More soon: data-art.info

For the German election we wanted to use a cartogram of German election districts but didn't find anything good, so we created our own. Here's a little nerd thread how the final algorithm worked 🤓 🧵 #gis #cartogram #election #datavis #cartography

I am very excited to announce Unpic 1.0 🎉 As easy as an <img> tag but generates all the right attributes and styles for a responsive image. No downloading and no build-time resize • Components for ten frontend frameworks • Support for 26 image providers, now with type-safe transforms for every one

this is so good. this is so so so good. i'm running around my office screaming the lev manovich quote about how software is ideology

Lovely example of how weird real-world data is. I put all 55 million points in Overture maps into a Nomic Atlas map. Lots of points spuriously appearing in the ocean. But the 1° square around 'null island' (0° lat, 0° long) is suspiciously clear -- someone has cleared out bad data just there.

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography

Anne Telnaes, Pulitzer-winning editorial cartoonist for the Washington Post, has resigned. The paper censored a cartoon that criticized billionaires. Democracy dies in broad daylight, too. anntelnaes.substack.com/p/why-im-qui...

Wenn ihr mit einer hoffnungsfrohen Karte aus dem Jahr gehen wollt: 2.500 neue Windräder haben 2024 eine Baugenehmigung bekommen, laut unserer Zählung @zeit.de. Die meisten davon gehen in den nächsten Jahren ans Netz und liefern grünen Strom. Die Energiewende geht voran! zeit.de/energiemonitor

2024 geht zuende - das heißeste Jahr weltweit & in Deutschland. Die Folge: krasse, teure Wetterextreme. Schaut den Jahresrückblick. Wir dürfen die #Klimakrise nicht weiter als Nebensache behandeln! Dafür würden wir & unsere Kinder & Enkel bitter bezahlen. youtu.be/XEH3NZkTdNI?...

Fascinating exploration of entropy as a measure of ignorance. Researchers are attempting to capitalize on the apparent subjectivity of that ignorance. By @zacksavitsky.bsky.social with terrific interactive graphics by Jonas Parnow and @markabelan.bsky.social: www.quantamagazine.org/what-is-entr...

New blog post out (first one in over a year 🥵): I tested how well different election dashboards implemented common dataviz accessibility principles, and explained where things went wrong, including lots of demos. fossheim.io/writing/post...

There’s more to rainbows than the human eye can see: here’s how a rainbow extends into the infrared and ultraviolet. Photos: 1. Infrared 2. Visible (obviously) 3. Ultraviolet, and 4. A composite showing how UV is beyond the violet in a rainbow, and IR beyond the red end. 🧪 #photography

HOW TO GET STARTED ON DATAVIZ BLUESKY 📊 IN 9 STEPS If you're arriving here, you may wonder where is the dataviz community and how to partake in it. Here's a thread on how I suggest going about it. 🧵👇

Unter vielen guten Plakaten heute war das eines der bedten (habe natürlich vorher gefragt, ob ich es fotografieren und posten darf).

Absolutely love this chart - all sorts of stuff you can see going on, much clearer than a Sankey diagram and in particular easier to make comparisons between different effects

It’s freezing cold. Global warming is solved!
