Earth planet liquid outer core rotation, created using pixray AI image generator : https://replicate.com/pixray/text2image The Earth's core is composed of two parts, the liquid (molten) outer core and the solid inner core. The inner core spins while floating in the outer core in the same direction, but not necessarily at the same speed, as the … Continue reading As the inner core turns #365papers

Below is a “lab note” from the Jaws of Life Project on experiment.com. Access the note and support the project here. Part of this project is gathering the funds needed to perform the necessary chemical analyses. The other part is gathering jaw bones from far and wide (only legally, of course), so that we have … Continue reading I have this jaw I’d like to give you…

Below is a “lab note” from the Jaws of Life Project on experiment.com. Access the note and support the project here. How do we know what teeth we have when we find a jaw or an isolated tooth? Let's start with a simple, yet common case: The lower jaw of a deer or sheep. For … Continue reading Let’s talk teeth – is this the third molar?

Below is a “lab note” from the Jaws of Life Project on experiment.com. Access the note and support the project here. As we describe this project, we refer to the "chemistry" of tooth enamel. Chemistry can mean a lot of things, so what does it mean in this context? Let's start with tooth enamel. Tooth … Continue reading What chemistry?

Below is a "lab note" from the Jaws of Life Project on experiment.com. Access the note and support the project here. This project was born from the practical need to be able to maximize our ability to learn about past environments using the geochemistry of fossil teeth. There have been a few studies, some published … Continue reading Some early data and how this works

I'm working on a project that was just launched on experiment.com. I refer to it as the Jaw Prawject or the Jaws of Life Project. It's a project to better understand how stable isotopes are affected by tooth position in mammal jaws. The goal is to determine if the dogma of only using the third … Continue reading The Jaw Prawject
