Fantastiskt förvärv av ÅA, grattis!

A genetically encoded device for transcriptome storage in mammalian cells Understanding how cells make decisions over time requires the ability to link past molecular states to future phenotypic outcomes. We present TimeVault, a genetically encoded system that records and s...

So cool - someone finally hacked 'the vault'.

Nature’s 10: Ten people who shaped science in 2025 A fired public-health official, a mosquito breeder and a baby with a smile seen around the world. These are just a few of the remarkable people chosen for Nature’s 10.

A fired public-health official, a mosquito breeder and a baby with a smile seen around the world. These are just a few of the people who shaped science this year and were chosen for Nature’s 10. 🧪

What’s the alternative? Have PhD students that you don’t mentor? Is an unmentored PhD student really a student?

The dust has settled after this year's SSI-meeting at karolinska institutet.
Thanks to everyone who made it a great meeting 🤓🔬🧬

We still can’t predict much of anything in biology Biology is hard. Yes, even for AI.

AI in biology: "I read about some new computational method...get excited because it’s exactly what I need...I try the method...Most of the time things don’t work...I have seen this play out so many times my default assumption is nothing is going to work" blog.genesmindsmachines.com/p/we-still-c...

BREAKING: The Nobel Prize in Physiology or Medicine has been awarded jointly to Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi "for their discoveries concerning peripheral immune tolerance"

Stay tuned for more.

Adipose tissue-derived fibroblasts engage in immune-stromal crosstalk during obesity-aggravated atherosclerosis in mice Background Atherosclerosis is a common disorder where changes in vascular wall and in the surrounding perivascular adipose tissue are evident. However, how multiple cell types contribute to the diseas...

Our newest preprint is out! I'm super proud of this work.

We found:
Obesity turns some adipose tissue-derived fibroblasts into immune-active players in a highly atherogenic atherosclerosis mouse model.

I also don't recommend going for a three-day hike during a heatwave 🥵

Reminder to all the scientists: Touch grass 🌿

Shimon Sakaguchi presented this on Monday, looks very promising!

Super cool microscopy images!

First full day of the ENII Summer School on Advanced Immunology in Alghero, Sardinia is done! So far it has been fantastic! 🤯 @rantakarigroup.bsky.social Nick doing what he does best in the picture, talking 😉

Thanks for a great talk, I learned a lot! 🤩

We de-extincted dire wolves. Be honest. We created a dire wolf. Be honest. It's a genetically modified puppy dog. Thank you.

An absolute #mustread showing how much the publishing industry is using and abusing scientists for profit. And with a bonus metric to catch fraudulent citations, the #impactinflation

Exclusive: NIH to terminate hundreds of active research grants Studies that touch on LGBT+ health, gender identity and DEI in the biomedical workforce could be terminated, according to documents obtained by Nature.

I never imagined I'd see this day, but clearly I didn't have enough imagination. NIH is going to terminate ongoing (and of course all future) research that focuses on gender identity, inclusion, environmental justice, anything "deemed DEI" etc. www.nature.com/articles/d41...

🙋

To be fair, it took years before I learned the difference between "TRANSGENIC" and transgender as well 🫠

NIH hoitaa tieteen hakukoneita, jotka ovat joka päivä välttämättömiä bio/lääketieteessä koko maailmassa. Ne ovat nyt kaikki kumossa. Ei liittyne siihen, että DOGE veti eilen töpselin kokonaiselta valtion IT-osastolta. Mutta muistuttaa, miten tärkeä USA on koko maailmalle - eikä vain sotahommissa.

Registration for THE 50th SSI-meeting in Stockholm opens soon! We hope to see many of you there! #SSI2025 #ScandinavianSocietyOfImmunology

Hi Justin,
very much enjoying reading the paper so far!

I found a small error in the results where it refers to fig. 5c-e, when it is actually should be extended fig. 5c-e.

👩‍🔬Happy International Day of Women and Girls in Science! 🎉 🌟

Today, we celebrate the incredible contributions of women in science and want to hear your story!

Share your experiences, challenges, and successes as a woman in science!

Dietary fructose enhances tumour growth indirectly via interorgan lipid transfer - Nature Dietary fructose enhances tumour growth in animal models of melanoma, breast cancer and cervical cancer indirectly via metabolite transfer.

Liver metabolizes high fructose corn syrup to fructose, which leads to increase production of LPC lipids that promote tumor growth.

Wonderful to see the #immunology community growing here.

The first starter pack is full (they cap at 150), so I created a second one. Let me know if you'd like to be added
