In the supplement of Kristian Carlson and colleagues' paper on the MH1 endocast [1], there's a nice comparison of the medical CT versus synchotron images. My blog sizing can't do it justice, and to be honest, the online PDF in Science doesn't either, but you get the idea:

Figure S10 from Carlson et al. 2011, detail. Original caption: Comparison of the same slice of the MH 1 cranium obtained with medical CT (left) and synchrotron scanning at the ESRF (right). Voxel sizes are approximately 450 μm and 45.71 μm, respectively.

You know, someday we'll all have these data for the entire fossil record, and students won't think a thing of it.

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
