I’m very happy to announce that my very first paper is out now in GCA! In essence: The C3 plant paleo-CO2 proxy doesn’t work for Ginkgo, and we shouldn’t expect it to work for a lot of other plants. A 🧵... sciencedirect.com/science/ar…

The NSF just eliminated geoscience postdocs, is trying to destroy NCAR, and is now dismantling the world's best array of ocean observatories for no reason, just uncomprehending childlike spite towards anyone who wants to learn anything about this planet nytimes.com/2026/06/01/clima…

Trump Administration to Dismantle Ocean Monitoring System

The $368 million network of instruments collecting data in both the Atlantic and Pacific has been critical to climate and ocean research.

Hey everyone! Check out our new paper on the evolution of cranial kinesis in birds out in PNAS! pnas.org/doi/10.1073/pnas.24… We used 3D muscle modeling, linkage mechanics, and phylo methods to investigate feeding across the dino-bird transition 🦖🐦‍⬛(1/?)

Avian cranial kinesis is the result of increased encephalization during the origin of birds | PNAS

The origin of birds represents a pivotal transition in vertebrate evolution, marked by significant changes in both brain size and feeding biomechan...

For the Megalodon, EVERY week was #SharkWeek.

What did Megalodon eat? Anything it wanted — including other predators

New Princeton research shows that prehistoric megatooth sharks like the Megalodon — the biggest sharks that ever lived — were apex predators at the highest level ever measured.

Our newest paper is out, which details the work we have been doing over the last 4+ years to improve throughput and consistency across users for the oxidation-denitrifier method, prompted by the rapid increase in applications of this method. analyticalsciencejournals.on… @AMG_lab

Analytical improvements and assessment of long‐term performance of the oxidation–denitrifier method

The analysis of the nitrogen (N) isotopic composition of organic matter bound to fossil biomineral structures (BB-δ15N) using the oxidation–denitrifier (O–D) method provides a novel tool to study...
