Our Approach to Climate Policy Has Failed. It’s Time for Climate Realism U.S. policymakers need a new strategy to confront the risks of climate change, compete in the global energy transition, and stay the course regardless of which political party is in power. A doctrine…

"climate realism" reading a lot like "sacrificing the global south and just shooting for 3 C"

Engineered heart muscle allografts for heart repair in primates and humans - Nature Epicardial engineered heart muscle allografts from induced pluripotent stem cell-derived cardiomyocytes can safely and effectively remuscularize chronically failing hearts in rhesus macaques, leading ...

Incredible work! A study years in the making published in Nature. I’ve been waiting for this one.

Engineered heart muscle patches from iPSC improve cardiac function in non-human primates…and are stable/show evidence for remuscularization in a human patient! Wow! ❤️

Graphical abstract depicts automated setup to generate 3D cardiac mini tissues consisting of 3 cell types seeded into 384 well plates. The cardiac tissues are monitored using calcium traces to detect arrhythmias and subsequent rescue after compound addition.

🔥Super excited to drop our recent preprint🔥

Here, we automated the generation of 3D Cardiac Microtissues and performed a small high-throughput screen to identify several novel anti-arrhythmic compounds for CPVT1 🧪❤️

Personalized miniorgans could speed treatments for rare diseases Method shrinks time for testing tailored RNA drugs from months to weeks

🥼 A new personalized method reduces the time spent tailoring RNA drugs—from months to weeks. In a @nature.com paper, scientists used patient-derived cardiac #organoids to predict how rare genetic diseases respond to treatments.

Created a starter pack focusing on disease modeling in a dish using stem cells! 🧪🔬

Please (self)nominate anyone you think should be added to the list and repost so it finds the right people ❤️

A thread about being wrong:

5 years ago, we wrote a paper about how how newly enfranchised 16-year-olds vote in Austria. But we were wrong.

This year, @elisabethgraf.bsky.social, @schnizzl.bsky.social, Sylvia Kritzinger and I are setting the record straight: authors.elsevier.com/c/1juT5xRaZk...
