As seawater gets colder, it gets more viscous. Hundreds of millions of years ago, these frigid physics may have helped multicellular organisms evolve on an otherwise desolate “Snowball Earth.” @vero_greenwood reports: https://t.co/4mGd7VCMcR

New preprint up, showing how snowflake yeast overcome one of the greatest limitations on the evolution of multicellularity: diffusion. They do so by leveraging emergent biophysics to rapidly flow media through their bodies, like a sea sponge. 1/28

@BeaBasel @umn Congrats!!

Geoscientists are not all gifted with artistic finesse when it comes to sketching what they see in the field. @Snapchat and other social media apps with easy photo and video editing tools can help. https://t.co/921wv50XCJ

Hi everyone, RMGS 2023 will be happening at CU Boulder on April 22nd! Registration is open, please see the flyer below for more info! Hope to see you all there!

[NASA Webb Telescope @NASAWebb]

👀 Sneak a peek at the deepest & sharpest infrared image of the early universe ever taken — all in a day’s work for the Webb telescope. (Literally, capturing it took less than a day!) This is Webb’s first image released as we begin to #UnfoldTheUniverse: https://t.co/tlougFWg8B

From the start, the Electoral College was a political deal — designed to give states with small populations more of a say in presidential elections. The framers expected it to evolve.

But the way we select a president has only been amended once, in 1800. https://t.co/crzIBAAoJg

Some of the $900 in grad student fees just paid to @CUboulder. The $275 "Fall Student Activity Fee" feels especially ironic as CU tells us to quarantine due to their failure in handling the pandemic. Friendly reminder to all my fellow grad workers to unionize @ucwcolorado

Stop asking candidates if they “believe in” climate change and start asking if they understand it.

It’s science, not Santa Claus.

I hit a wall in June/July. It started before that, then got worse. I wasn't alone but felt like I was. Thx to @acsifferlin, who saw potential in what I'd shared in a group, I turned my frustration into a story for others experiencing it too. Hope it helps https://t.co/ZvgkUrNbD9

I made these for my own education, but also want to share them. They are "bite-sized" summary of peer-rev'd articles (which I provide a QR code that directs you to them). I will be sharing a few a day, will continue this project for as long as possible. #Strike4BlackLives #BLM

I’m pleased to announce that the Department of Geological Sciences at CU Boulder has voted overwhelmingly to no longer require the GRE for graduate admissions. #GRExit

1/n How about some fireflies to start the weekend?

Thrilled to share our first firefly preprint on “Spatiotemporal reconstruction of emergent flash synchronization in firefly swarms” https://t.co/3qQLAcqyOm

No, #graduatestudents should not have to go into debt to enhance their careers. Proud for this to be my first solo #science publication @nature @NatureNews
