Yesterday, I had the honor of giving my tenure talk to the Purdue EAPS department. I won’t actually find out if I was successful until next spring, but no matter what, I am incredibly grateful to have had the opportunity to be a faculty member here and thoroughly enjoyed the last 6 years. #boilerup

A cadre of iron-rich extraterrestrial particles picked up faint whiffs of our planet’s atmosphere when they fell to Earth millions of years ago.

Mineral Monday: The Handbook of Mineralogy on MSA’s Website Where can you find quick and handy information on 5,663 minerals, both common and rare? In the Handbook of Mineralogy of course. It is available as a set of hardcover volumes, or on the MSA website (handbookofmineralogy.org).

Through social media, talks, and more, @drwendyrocks.bsky.social shares the joy of understanding our planet with audiences that might otherwise have never taken a second look at a rock. buff.ly/fSaRJCX Read more in our August issue: bit.ly/Eos-Aug2025

Turns out, most meteorites come from only a few places in the asteroid belt. This could help scientists understand where to send future asteroid exploration missions. eos.org/articles/a-g... Read more in the July issue of Eos: bit.ly/Eos-Jul2025

Fellow Geoscientists! We encourage you to attend the third Gordon Research Conference (GRC) on Geochronology (www.grc.org/geochronolog...). This GRC conference will be held August 17-22, 2025 at Sunday River, Maine. The deadline to apply to attend is July 20, 2025!!

🚨 New paper from the T@P group! 🚨 We performed diffusion experiments on laboratory deformed apatite samples, and demonstrated that the deformation-induced dislocations can create helium diffusion 'sink' like behavior observed in some natural samples. Check it out!

I am so very proud of Dr. Moshammat (Moe) Mijjum, who successfully defended her Ph.D. on Wednesday and is the first Ph.D. student from our research group at Purdue!!!

Do you want a big overview of NSF, explaining things like the fact that 24% of all federally funded academic fundamental research comes from NSF? And that 94% of its budget goes out the door in grants/awards? Here you go. nsf-gov-resources.nsf.gov/files/Factsh...

A nice tribute in honor of Dr Laura Crossey, who has recently retired. I feel very fortunate to have had her as a mentor and role model! www.nmepscor.org/news-and-eve...

Proud advisor week! PhD student Moe Mijjum had her first, first-author paper published in Meteoritics & Planetary Science, and she's got another accepted paper that should be out soon!

🚨New paper just in time for the holidays 🚨 We combine exposure ages, glacial geomorphology, and sea level data to show that this pile of rocks near Thwaites Glacier is a moraine that formed in the Late Holocene (~1.4 ka) when a glacier thickened/advanced tinyurl.com/4sanafnb 🧵

Welcome all the Bluesky newcomers 🤗

Congratulations to Emily Judd and the entire Phantastic DA team on this temperature reconstruction www.science.org/doi/10.1126/...

A happy update: I resubmitted the same paper to another journal, and received FOUR REVIEWS within 1 month of that submission! Thank you to the editor who did the hard work of finding reviewers and to the four individuals who said YES! PS - on the whole they like the paper 🤗

So much discovery came from the Joides Resolution. Hopefully NSF will find a way to revitalize the vital window into earth’s past that deep-sea drilling provides (gift link): www.nytimes.com/2024/08/26/s...

When a journal rejects your manuscript two months after you submit it because they were unable to find reviewers 🫠

Hey All! We're looking for a glaciology PhD student at DTU-Space to model the ice flow of the Greenland ice sheet over the past 12,000 years. 👇 efzu.fa.em2.oraclecloud.com/hcmUI/Candid... The CISP team is fun and growing! This call closes 16 August 2024.

Wow, very sad news to learn today. It was a pleasure getting to work with David on a large collaborative project when I was a PhD student.

The Natural History Museum of Denmark is looking for a new Assistant, Associate, or Full Professor of Geology! Come and join our museum at perhaps the most exciting time in its >300 year history! employment.ku.dk/all-vacancie...

Being indoctrinated with @ickert.bsky.social

First look at the orex sample from bennu. Such amazing preliminary science of a carbon and water rich rock. Geology ⚒️🧪

@ickert.bsky.social 👀👀👀

Looking for a tephra chronologist or tephra ID-ing lab that works on ashes collected in the four corners region of the USA. Not looking for U-Pb age, but geochemical correlation ID. Any ideas? Thanks!

Our group at Virginia Tech is recruiting a Ph.D. student to work on a NASA funded project looking at changes in the environment and biogeochemical cycles between the Cambrian Explosion and Great Ordovician Biodiversification Event. (1/2) ⚒️

If you like the K-Pg boundary and/or Bayesian inversions, check out this paper out today in Science by my @dartmouthears.bsky.social MS student Alex Cox!! www.science.org/doi/full/10....

When it rains it pours; I sent out 1 manuscript to coauthors and received 3 coauthor manuscripts to edit within 7 working days. Guess you know where you can find me for the next little while:

Wow this is super cool!! Will definitely be sharing with folks I think might be interested in the #geoscience community ⚒️

FAT BEAR WEEK VOTING IS OPEN

Today I submitted my first final report for a grant that ended. Feels pretty good! We did some cool science studying the diagenesis of fossil gar scales. TLDR, they aren't great for #geochronology. Manuscript led by my former MS student is forthcoming!

Oo thanks for the reminder! Ordered ✅

Why though 😭

Congrats to the #OSIRISREx team!!! You punched 🤜 the asteroid and then you kissed 💋 the Earth!!! Can’t wait to hear about the mass estimate 👀

And the #OSIRISREX samples are on the ground. Here's our story about why that's important and what happens next: www.nature.com/articles/d41...

Thank you for the invite code, @alisabokulich.bsky.social! Happy to move to this platform 🤗
