For as long as I can remember, I’ve always been much more interested in what was above my head than what was below my feet. But this project showed me that looking down and back in time can be an important step toward the future of how we study worlds beyond.
New PNAS study shows that life’s signature lingers in rocks long after the original biomolecules are gone. Hazen, Wong (@miquai.bsky.social) & Prabhu (@anirudhprabhu.bsky.social) found chemical traces of ancient life in 3.3 BYO rocks.
Let’s get into it. (1/6)

Thoughts are with everyone in Jamaica and Cuba right now.
Cuba's second largest city (Santiago de Cuba) looks like it will be close to the eye and on the dirty side at landfall and that bay and low-lying nature of the city is really worrisome, thinking about surge.

And here is the updated color summary for #MinCup25!
Colorless (white-grey-black) minerals were quickly kicked out, unfortunately. Maybe next time, there can be a max color level for participation? Tenebrescent #tugtupite can participate again and take a glorious win after exposure to UV ;-)

Thermo25 was a great conference! Got to soak up the state of the art in thermochronology in one of the prettiest places I've ever seen - Kanazawa, Japan

Optimism may seem like it’s in short supply these days, but I fervently believe we must give ourselves permission to hope. Whether it’s looking for life in the universe or fighting for a brighter tomorrow here on Earth, optimism alone won’t be the solution to our problems, but it can be a start.

Not sure who needs to hear this, most of the stuff that government does is because a) society has determined those services are valuable and are willing to pay for it, and b) there is no private sector model to do most of those things.

I didn't think I would ever get a reason to feel kinship with Lady Gaga: "The chaos I thought was long gone is fully intact and ready to greet me whenever I’d like."
First field season of 2025 is in the books and I miss it already.
