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.

It was exhausting but fun and forced me to think more carefully than before about complex bedforms.

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! π§ͺβοΈ

Slide with text βSupport Society Journals: Society-based journals help build and advocate for our scientific communitiesβ showing the logos for non profit publishers ASM, ACS, ASBMB. microbiology society, Science, and ISME. Underneath βfor-profit journals do notβ showing logos for Nature, Elsevier, Frontiers, CellPress, and MDPI.
A reminder to please support non-profit publishers.
Itβs good for science and scientists.
Itβs 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.
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. "Devastatingβ was how one student described it to me. #GradSchool #NSFGRFP

For those anxiously awaiting it: the NSF GRFP solicitation is out, with a November 14 deadline for Geoscience applicants: www.nsf.gov/funding/oppo...

An even tighter crop, focusing more on the pika's eye.
An extremely tight crop of the pika's eye, emphasizing their reflection of an early morning mountain scene.
"Pat, why do you carry that ridiculous 600mm lens on long hikes?"
Buddy, I can see mountains reflected in the eyes of a trailside pika.
