In somewhat terrifying but hopefully positive personal news, I've decided to purchase an extremely expensive 10x10 booth in the exhibit hall at the American Geophysical Union meeting in December. I'll be selling my gemstone and wire jewelry and art. I hope you'll come find me there.

Is it 100% agreed that lunar anorthosites are products of the early lunar magma ocean? An honest question coming from a bit of my own ignorance.

Serving as Editor-in-Chief at Science was fascinating. I greatly enjoyed working with talented and committed editorial, news, graphics, and production staff. But the inside look into scientific publishing and AAAS was also deeply disillusioning.

Happy Isotope Day everyone! 🥳On this day in 1913 Nature published Federick Soddy's paper "Intra-atomic Charge" www.nature.com/articles/092... in which he introduced the term "isotope" (coined after a dinner conversation in Glasgow with Margaret Todd the classics scholar). how will you celebrate?🧪⚒️🌊

New method for measuring nitrogen isotopes in tooth dentine at high temporal resolution. We demonstrate that developmentally informed SIMS measurements of N isotopes minimize time averaging and can be precisely related to an individual's early dietary history!
