I realize broad science-literacy problems cannot generally be solved just by shoving more facts at people but I really wish more people understood that the entire purpose and mechanism of a vaccine is to educate your OWN immune system, making it about the most "natural" medical intervention possible

Creative work in general pays far less than people think it does, especially relative to the notability one can have. The correlation between "fame" and "income" is rather shaky, especially the further down you go on the fame power curve. Lots of "world famous" creators are broke as hell.
Even though I *know* authors don't earn as much as it seems like they should, it's always mildly disappointing that even wildly popular authors make less than a lot of the rank and file in many industries that provide less value to actual people.

I got one of these the first time around and can say, being from the rainy Pacific Northwest, it's legit the best umbrella I've ever owned. 10/10 would recommend if you're in the market for an ultra-nerdy umbrella! ❤️
Please help me bring back the #DareMightyThings umbrella inspired by the Perseverance rover parachute! 🪂🤖
Sold out, but I really want to reorder them. To do that we need 25 pre-orders! ✨

Permanently shadowed craters on Mercury: amazing results!
• Older polar craters host more ice, suggesting steady-state processes drive long-term accumulation.
• Younger radar-bright craters imply recent resurfacing

I was a NASA Space Grant Student in my junior year of undergrad, it was through this program that I really started to see what a career in planetary science could look like and where I could fit within it.
Under the proposed White House budget, the NASA Space Grant program would be eliminated.
I was a NASA Space Grant recipient during my Masters—it funded my research on water on Mars.
I then went on to work in science & mission ops on multiple NASA Mars missions immediately after graduation. (1/2)
