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).

Wendy Bohon: Quelling Fears and Sparking Geoscience Joy - Eos This earthquake enthusiast and science communicator wants you to know that a “whole ecosystem” of scientific careers exists outside of academia.

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.

A Geologic Map of the Asteroid Belt - Eos Scientists leveraged a global camera network and doorbell cameras to track dozens of meteorites to their asteroid families.

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.

The 2025 GRC will be preceded by a Gordon Research Seminar (GRS) (www.grc.org/geochronolog...) planned by and for students and ECRs. The GRS is August 16-17 at Sunday River, and will include a mentoring session. Encourage and support your research groups to attend both the GRS and GRC!

The GRC provides an immersive experience for five days with colleagues in a collegial environment. The previous two Geochronology GRCs were very well received, and we still have room for more people to participate. We hope you will join us in August!

The theme of the 2025 GRC is the "Timing, Tempo and Drivers of Earth’s Climate.” We have an exciting lineup of confirmed discussion leaders and speakers, which you can find at the link above. These include geochronologists as well as scientists whose work is heavily influenced by geochronology.

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!

Moe's dissertation is: “Investigating the exposure and thermal history of enstatite (E) chondrites and improving cosmogenic noble gas production rate calculations for terrestrial and extraterrestrial applications." Congratulations, Dr. Mijjum!!!

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!!!

AGeS was so important for our community. An immense loss 😔

An “NSF BY THE NUMBERS” fact sheet screenshot with some facts about “ADVANCING SCIENCE AND ENGINEERING RESEARCH IN THE U.S. AND ABROAD” -The U.S. National Science Foundation was created by Congress in_ 1950 to continue the U.S. science and technology enterprise began during World War II. -NSF allocates 94% of its approximately $8.5 billion budget for grants and awards to support research projects, facilities and STEM education. -NSF funds research in all 50 states and U.S. territories. -NSF fosters international scientific collaboration on all 7 continents around the globe. -About 2,000 academic and other private and public institutions across the U.S. conduct NSF-funded research. -NSF supports 24% of all federally funded academic fundamental research at U.S. colleges and universities. fundamental research comes from NSF. - In 2020, NSF received approximately 43,000 research proposals from scientists and engineers and funded about 12,000. - NSF-funded researchers have received 248 Nobel Prizes.

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!

heading of journal paper

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!

A photo taken from a plane that shows a mountain (Mount Murphy, West Antarctica), moraine, and outcrops of a scoria cone, all of which are surrounded by ice and snow. A small glacier that flows from the flanks of Mount Murphy toward the moraine and scoria cone is highlighted in purple. Arrows show our interpreted ice flow directions.

🚨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 🧵

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 🤗

Dismantling the Ship That Drilled for the Ocean’s Deepest Secrets The JOIDES Resolution, which for decades was key to advancing the understanding of the Earth and its innards, concluded what could be its final scientific expedition.

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):

And the same journal sent me a reviewer request 2 days later 🫠🫠
