⚒️ The Proterozoic Earth had radically different ocean and atmospheric chemistry, was ruled by bacterial mats, and was possibly being shaped by not-plate-tectonics, or at least different-plate-tectonics.

Calling it boring is such a depressing failure of the imagination.

“That name, man,” Riedman says of the boring billion. “We’ve got to kill it. Kill it with fire.”

Gave me a smile to see they interviewed you about your work too.

I'm part of an online truck form were members will rely parts across the country to get them to you... I think we should set something similar here.

Last week I was co-leading a field trip in Utah, to check out some fluvial and eolian rocks. It was exhausting but fun and forced me to think more carefully than before about complex bedforms. This is a 3D model of one of the many stunning exposures of the Navajo Sandstone near Escalante 🧪⚒️

New co-author paper out today in @pnas.org led by the fantastic Dr. Lubna Shawar!

Lubna breathes new life into the sponge sterol hypothesis with her meticulous organic geochemistry, and the ID of two new sponge-derived C31 Steranes in ~600 Myr rocks. Check it out! 🧪⚒️

A reminder to please support non-profit publishers.

It’s good for science and scientists.

It’s a responsible use of taxpayer dollars.

It requires resisting peer pressure to submit to Nature journals.

Thanks @bacteriality.bsky.social for this helpful slide for microbiology journals.

Slide with text “Support Society Journals:
Society-based journals help build and advocate for our scientific communities” showing the logos for non profit publishers ASM, ACS, ASBMB. microbiology society, Science, and ISME. Underneath “for-profit journals do not” showing logos for Nature, Elsevier, Frontiers, CellPress, and MDPI.

Today was a hard day for Ph.D. students who found out that they can no longer apply for NSF's prestigious Graduate Research Fellowship Program. "Devastating“ was how one student described it to me. #GradSchool #NSFGRFP

Everyone writing about Perseverance today should be asking how many of the scientists and engineers who were involved in this discovery no longer work for NASA bc of Trump.

Buddy, I can see mountains reflected in the eyes of a trailside pika.

An even tighter crop, focusing more on the pika's eye.

If I wanted to spend a bunch of time building cool things only to see it burned down, I would have applied for a federal grant or helped build up a federal lab or sample depository.
