High-energy X-ray diffraction patterns from a
single grain of iodine-gadolinium-cadmium taken at Argonne National Laboratory’s powerful X-ray device, the Advanced Photon Source, with the beam parallel to the grain’s five-fold axis. Scientists can tell something about a material’s structure by the way it diffracts X-rays, with more powerful sources providing greater detail.
For this post, here’s a roundup of a few interesting Iowa science items over the last couple weeks, including obsessive-compulsive and obese mice, a new family of quasicrystals and pigeons pecking touchscreens. (In this case, shouldn’t they be called “peckscreens”?)
If you’re not in the fields associated with these projects, you may not have heard of them. As with a lot of other Iowa science, they didn’t get a lot of attention here at home.
