Of Mice and Methylation
Our quickfire round up of the most eye-catching spectroscopy research.
Matthew Hallam | | Quick Read
The pigments in ancient fossil samples can provide us with valuable insights into evolutionary processes, but methods to study them are scarce. Researchers recently developed a method to attribute red fossil pigmentation to organosulfur-Zn complexes using synchrotron rapid-scanning x-ray fluorescence and both sulfur and zinc x-ray spectroscopy. Using this method, the team could see that the fur of a three-million-year-old mouse fossil from Germany was probably a similar reddish color to modern field mice (Figure 1).
