If you see this, don't participate. It's a rigged study by Lisa Littman and unethical researcher J. Michael Bailey meant to undermine access to care. Spread the word.
“Screenshot of a promoted Reddit post by u/AYAGDOS. The post reads: ‘Navigating gender dysphoria? Join our confidential, cross-country study of 18–25 year olds to tell your story, challenge preconceptions, and have YOUR experience reflected in the science.’ Below is a banner graphic with the Northwestern University logo and the text ‘TRANS OR GENDERQUEER? SHARE YOUR STORY.’ The image shows a close-up of a hand with light pink nail polish, partially painted blue, held up against a blurred background. A link to ayagdos.org and a ‘Learn More’ button appear at the bottom, along with Reddit vote and share icons.”

I got Linux running in a PDF file using a RISC-V emulator.

PDFs support Javascript, so Emscripten is used to compile the TinyEMU emulator to asm.js, which runs in the PDF. It boots in about 30 seconds and emulates a riscv32 buildroot system.

A new framework inspired by mountain landscapes enables the classification of nonlinear physical systems by mapping their stable and unstable states, offering insights into abrupt phase transitions. doi.org/hbdbn4
Seeing physics as a mountain landscape for classification of nonlinear systems
Imagine standing on top of a mountain. From this vantage point, we can see picturesque valleys and majestic ridges below, and streams wind their way downhill.

Plants adapt to compacted soil by altering root structure, using engineering-like principles to strengthen outer layers and expand root diameter, potentially improving crop growth in challenging conditions. doi.org/hbcrvc
Plants use engineering principles to push through hard soil
Across the globe, soil compaction is becoming an ever more serious challenge. Heavy vehicles and machinery in modern agriculture compress the soil to such an extent that crops struggle to grow.

We saw it with big tobacco, we saw it with the fossil fuels industry. When their own internal research showed the harm from their product, the defunded the research and attacked independent researchers coming to the very same conclusions.
