Curious about the glacial geomorphology? Recent undergrad Regan Collins made this amazing ArcGIS Storymap about the formation of the Finger Lakes Region, complete with a map for a self-guided field trip to see some of the best examples of glacial geomorphology in the world! tinyurl.com/7w4asmwc

New publication alert! Congratulations to Patel and @rachelglade.bsky.social for their paper "When ice meets bedrock: variation in regional lithology as a control on the size variation of the Finger Lakes in Western New York ". Take a look here journals.psu.edu/geomorphica/...

We had a great experience publishing with @geomorphica.bsky.social! Using a simple glacial erosion model, recent undergrad Div Patel found that lithologic differences alone may be enough to explain size differences of the Finger Lakes in Western, NY. Check it out! journals.psu.edu/geomorphica/...

Using laminar(ish) flume experiments with xanthan gum as a proxy for cohesive biofilms, we found that changing cohesion alone can qualitatively alter channel morphology and dynamics, transitioning from braided, to single thread, to gully-like channels with retreating headcuts.

Replication Crisis

xkcd.com/3117/

4-panel comic. (1) [Person 1 with ponytail flanked by person with short hair and another person speaking into microphone at podium] PERSON 1: In the early 2010s, researchers found that many major scientific results couldn’t be reproduced. (2) PERSON 1: Over a decade into the replication crisis, we wanted to see if today’s studies have become more robust. (3) PERSON 1: Unfortunately, our replication analysis has found exactly the same problems that those 2010s researchers did.

A beautiful paper about a ubiquitous pattern- I'll never look at ripples the same way again!

Kurt Vonnegut man

Kurt Vonnegut tells his wife he's going out to buy an envelope:
"Oh, she says, well, you're not a poor man.
You know, why don't you go online and buy a hundred envelopes and put them in the closet?
And so I pretend not to hear her. And go out to get an envelope because I'm going to have a hell of a good time in the process of buying one envelope.
I meet a lot of people. And see some great looking babies. And a fire engine goes by.
And I give them the thumbs up. And I'll ask a woman what kind of dog that is. And, and I don't know. The moral of the story is — we're here on Earth to fart around
And, of course, the computers will do us out of that. And what the computer people don't realize, or they don't care, is we're dancing animals. You know, we love to move around.
And it's like we're not supposed to dance at all anymore."

Amidst an onslaught of bad news, I'm very happy to report some *good* news that JohnPaul Sleiman, DRIP Lab PhD student, just published his very first paper in Icarus! We find that lobate patterns on Mars are likely similar to those found in arctic regions on Earth. Congrats JP! tinyurl.com/3mwrarm2

The lab is run by just seven federal employees who have been paying out-of-pocket for their own coffee since 1973.

Excited to share our new paper in @pnas.org doi.org/10.1073/pnas...! Ice cubes often appear cloudy because, as water freezes, air bubbles get trapped and scatter light. But how does freezing rate affect the shape of the bubbles?
