Ancient, distinct, continent-sized regions of rocks, isolated since before the collision that created the Moon 4.5 billion years ago, exist hundreds of miles below the Earth’s crust, offering a window into the building blocks of our planet, according to new research.

How a Geochemist Really Dresses
I am a geochemist. For my PhD thesis, undergraduate, and summer internship research, I have spent thousands of hours in geochemistry labs. I enjoy labwork, and I take laboratory safety seriously. When I work in the laboratory, I usually wear an outfit similar to the above. In the above photograph I am wearing an acid-resistant lab coat, long pants, closed-toed plastic lab clogs (out of the picture, but believe me), …

Bad Hotplate
When it comes to laboratory safety, you should never cut corners to save money. A few months ago, I had a teflon beaker melt on a yellow hotplate which we had purchased for the lab to replace a hotplate that died. Unfortunately, when inexpensive hotplates “die” they tend to heat up very hot, which can be very dangerous. I’m not sure exactly what happens, but I think that over time …
