Things I'm interested in: evolution of planetary systems & habitability; nucleosynthesis; neutrinos; stellar influence on planetary & satellite bodies, their atmospheres & habitability; relativistic propulsion methods; interstellar exploration; astrobiology & extremophiles.

With the Guardian reporting that “UnitedHealth managers pressed nurse practitioners to persuade Medicare Advantage members to change their “code status” to DNR even when patients had clearly expressed a desire that all available treatments be used to keep them alive,” I thought I

I am not sure if anyone cares what a 27 year old with autism and special needs has to say, but I want to help inspire others. I lost both my parents when I was 19. I was attacked and bullied. But it hasn’t broken me. Can you share this post if you care what I have to say?

NEW: NASA is about to send an audacious spacecraft to paint a portrait of an icy moon hiding an ancient ocean. It’s called Europa Clipper. And it’s going to change the way we understand not just our world, but every world, everywhere. Me @NewsfromScience https://t.co/sidKCBHPGC

Here's how we plan to confirm its existence and learn more about it: https://t.co/ql2DI8uxSb

Did you know ❓ Scientists suspect that hidden beneath the icy surface of Europa, the fourth largest of Jupiter’s 95 moons, is a salty-water ocean thought to contain twice as much water as Earth’s oceans combined! 📸 NASA/JPL-Caltech/SETI Institute

Not a lot phases me, but the trifecta of: *Several major events that overlap *Above events happening during hurricane season (in a prone area) *These events happening on the wrong end of a possible government shut down ... is making me very nervous.

The U.S. government's 2025 fiscal year begins on October 1, 2024, but no funding bills have been passed, including the one for NASA. If Congress doesn’t act by midnight on September 30, the government will shut down. Learn more. ⬇️

We know social media is rife with medical misinformation (wearing glasses is good, actually). This isn't great when 1 in 5 Americans turn to TikTok before their physicians, so I made this free guide to social media to share with the healthcare professional in your life!

The last several months have been pretty hairy. Red about the herculean effort of our engineers and scientists who pulled off something miraculous... and in record time.

"We can't afford to have so many hospitals, emergency rooms and clinics closing their doors," says #CMADocs President Dr. Tanya W. Spirtos. #Prop35 prevents the state from redirecting health care funds.
