1/ Mitochondrial Na⁺ links metabolism, Ca2+ signaling and disease. We know how it gets in, how it gets out, and proteins that use it. But: we've never actually seen Na⁺ in single mitochondria in live cells. We started with an unusual observation, went down a rabbit hole & found some cool biology .

I'm very grateful for all the support from the Wallenberg foundation that my lab has got over the years!

Feels like this paper on protein-templated DNA synthesis by a natural enzyme warrants some comment. So here's a 🧵. /1 www.science.org/doi/10.1126/...

Insane but true

🧪🧬 You can now play Minecraft with DNA nanotechnology! In our latest preprint we introduce DNA polycubes platform: A modeling driven system, where we use SAT-solvers+multiscale simulations to design 3D finite-size structures that assemble in high yield chemrxiv.org/doi/full/10....

Weird statement by Rutte. First, it is obviously wrong. Given time and the necessary investments, Europe can of course defend itself without U.S. And second: Why undermine European deterrence like that? This message increases the risk that Putin will try to exploit the current fracture in NATO.

When Europe shows its true strength, dictators back down. Apply this lesson to Russia.

Our new paper is out! Tracking the stability of DNA origami in-vivo is typically done with fluorescence, but are they still attached to intact DNA nanostructures? Here we introduce PLASTIQ, a method to quantify the structure of DNA nanostructures using tiny blood samples, ligations and PCRs!

BIG FIGHT AT POLAND’S WROCLAW ZOO!!!

full video, obtained by NBC News, that was apparently filmed on a cell phone by the ICE officer who shot Renee Good

It's clear this is the "shooting someone on 5th Avenue" moment right? No one is still waiting for him to be actually there in Manhattan holding the gun?

Nanopore sequencing of peptides, exciting possibilities ahead also for the microprotein field.

THREAD The first full year of tracking research on @bsky.app Hi, we are Altmetric, and we track how research is communicated across the web. We now have one full calendar year of Bluesky research data and thought we'd have a looksie.

🥳

So the EU could not agree on using the frozen Russian assets to fund Ukraine. Are we trying to be the new Switzerland? “Let us take care of all that money while you bomb and rape your neighbor.”

These arguments come up regularly, that science funding shouldn’t require grant applications because they waste time. But what is the alternative? To rely on universities' internal politics to be able to efficiently... https://bjornhogberg.micro.blog/2025/12/13/these-arguments-come-up-regularly.html

Latest #CDlab paper out in Molecular Cell! see this thread by @RomanBarth2

Ukraine accomplished to pass a UN resolution that recognizes the tragedy of Chornobyl - NOT as RU spells is “Chernobyl”; and Russia’s fault. For years, they’ve claimed their narrative passing THEIR resolutions. For the first time Ukraine accomplished to recognize the truth. Check who voted against

Maybe its time to start posting something.

for those claiming "my head went to putin instead of trump" - no. The russian "logic" is to control trump and his behavior. Someone involved, should know. This was before Trump's first term, during, after and is now. Nothing has changed. Both pro and anti kremlin messaging is kremlin approved.

IT'S HAPPENING! 💥 I'm psyched to launch the collaboration between @qedscience.bsky.social & @openrxiv.bsky.social @biorxivpreprint.bsky.social! Preprint + q.e.d = your science is out there, and anyone can appreciate it. Let's care about making discoveries, and not on “getting published” (1/3) 👇

This video is worth watching. It's easy to lose track of all the fraud going on right now. youtu.be/JMEJTORMVN4?...

A few comments on Trump's dealings with Ukraine: 1. He turned against Zelensky when Zelenky refused to falsify evidence against the Bidens. 2. At that time, Trump & Giuliani worked with men such as Andriy Derkach that US intelligence verified as belonging to Russia intelligence

On this date in 1939, the USSR invaded Poland in cooperation with its ally, Nazi Germany. www.hachettebookgroup.com/titles/timot...

Cutting of air defense ammunition to Ukraine at this point is pure betrayal by the US. A stab in the back.

Now I've looked more closely at these two recent papers in Nature, and they are both excellent examples of why we need new narratives for talking about molecular biology to non-specialists. 🧵 www.nature.com/articles/s41... www.nature.com/articles/s41...

It’s out! 🚨 📣 Excited to see that this collab led to my first paper as one of the first authors—now published in Small @wiley.com 👩‍🔬 In this study, we explored the binding dynamics of DNA origamis with the cell surface at the single-particle level. Check it out! doi.org/10.1002/smll...

Applications are now open! We are recruiting 20 Assistant Professors in a wide range of subject areas. We're looking for early-career researchers with strong scientific merits and future potential. 🔗 All positions: ki.se/en/about-ki/...

What’s Kerch bridge doing? 🙂

Full house at the Nobel Forum as @kragesteen-lab.bsky.social kicks off MBB’s new lecture series celebrating 1982 Nobel Prize winners Sune Bergström and Bengt Samuelsson. And @itaiyanai.bsky.social’s inaugural keynote lecture was as inspiring and entertaining as you’d expect! 🤩

This is exactly what is on the table.

#FNANO in Snowbird a gem among conferences. I went here for the first time as a PhD student in 2005. This year two of my students, Iris and Igor, gave presentations.

Trump pleads with his war criminal patron "Vladimir" over social media not to make him look too stupid as Trump gives everything to Russia and justifies past murder and enables future murder. And Putin laughs at him.

Trump’s Russia “deal” makes Neville Chamberlain look like Churchill

And Trump is upset with Zelensky...

Ruzzia bombing civilizans. Scum.

34 dead and 117 injured and this is what U.S. Secretary of State Rubio comes up with on the Russian missile strike in Sumy: "A tragic reminder of why President Trump has pushed to end this war." No Marco, it is a tragic reminder of how ineffective your administration is in 'resolving' this war.

3yo Tymofiy 7yo Radyslav 7yo Arina 9yo Herman 15yo Danylo 15yo Mykyta 15yo Alina 16yo Kostiantyn 17yo Nikita President Zelenskyi published the names of kids, innocent victims of the russian terror attack against Kryvyi Rih residential district yesterday. Never forgive. Never forget.

Elbows up Heard and McDonald Islands. You'll show them!

Trump is imposing a 10% tariff on the Heard and McDonald Islands. The Heard and McDonald Islands are uninhabited.
