If you can believe it, this is the same bird a year apart. We caught this gorgeous male Scarlet Tanager in 2024 and banded him. He flew all the way to South America for the winter and then came right back to Iowa where we caught him again in the same net.
Nitrogen is an essential element for life on Earth. Interested in its relationship to major evolutionary events in oceans the past ~four billion years? If so, check out a new @Nature review paper my advisor and I chipped in on! doi.org/10.1038/s43017… @GeologistBen
📢 Woot, woot! Our work is on the cover of Trends Microbiology, June 2024 issue - a special issue dedicated to microbial nitrogen transformation! 🎉🎉 Read the article led by Holly Rucker @hollyr_rucker ➡️ cell.com/trends/microbi… @TrendsMicrobiol @CMB_UWMadison @UWBact
Behind every scientist is a fantasy/sci-fi series they love with their entire heart (LOTR/Star Trek/etc)… mine is the Southern Reach Trilogy by @jeffvandermeer (this tweet is an attempt to get you to READ IT!!!!)
Worried you are starting 2024 without the recommended dose of iron-rich rocks from the Paleoproterozoic? If so, check out our new paper (and my #firstpaper !) on identifying mineralization pathways in the Biwabik Iron Formation! (1/3) 🔬🪨🌊
Much thanks to the awesome coauthors who made this paper happen! link here--> 📷 pubs.geoscienceworld.org/msa/ammin/arti…
We found that sediment horizons cemented by silica contain well-preserved diagenetic mineral reactions, and that we can use these reactions to identify the earliest-forming minerals in these enigmatic, ~1.9 billion year-old rocks.
critical support for the javelina as they lead the war on arizona golf courses
Come along with me on my carnage (I mean course) check this morning. What should be one of the most beautiful golf courses in the country is being destroyed by herds of javelina. If anyone has a contact in AZ state govt that can help us find a solution please pass it along.
Vote #zircon! A lone timelord can be seen center-stage in this hastily-taken image of a sandstone. Under the petrographic microscope, they appear as colorful, high-relief crystals in cross-polarized light. A great tool for providing max depositional ages in sedimentary rocks!
It's the #MinCup23 FINAL ROUND!! 32 minerals have battled for your hearts, but only one can claim the Championship. Will it be #Zircon, the eternal timekeeper, or #Perovskite, the cubical rain on brown dwarf stars? Vote: mineralcup.org/2023/campaigns… Results: mineralcup.org/2023/campaigns…
@MineralCup As a philosopher of geologic time I have to go #TeamZircon! Vote for the oldest bits of Earth that still exist today-the resilient time capsules that allow us to reconstruct ~ 4.37/4.53 billion years of Earth's history! #MinCup23 bokulichorg.files.wordpress.com/2020/09/bokuli… npr.org/2022/12/28/114…
With the new Oppenheimer movie having been recently released, we figured sharing the story again of when he visited @IowaStateU as part of a Physic's Dept Carlson Lecture Series in 1954 would be appropriate isuspecialcollections.wordpress.com/2022/02/17/j-r…
I'm ✨INCREDIBLY✨ excited to share our new paper with you!! 📢"#PlasticPollution in riverbeds fundamentally affects natural sand transport processes" nature.com/articles/s4324… #FlumeFriday #River @CommsEarth @nature @IceMeanders @bedform Here are our key findings: 🧵1/5
It's published!! It's here!! My first first-author paper is out for your viewing pleasure 🎉 🎉 🎉 We found that quagga mussel tissue CNP varies (a lot!) in the upper Great Lakes & impacts mussel excretion rates & stoichiometry 🌊🦪 Check it out!! link.springer.com/article/10.100…
Excited for Pat Duncanson to become the 87th Chair of the University of Minnesota Alumni Association Board. Congratulations Pat!!
In Minnesota, the southern edge of a boreal forest ecosystem could shift over the Canada border this century. Local photographers, scientists, and land managers are grappling with what that means. #BirdsTellUs audubon.org/magazine/fall-…
