Elemental and chemically specific X-ray fluorescence imaging of biological systems
From the perspective of a chemist, biology confers a rich variety of roles on a number of
metal ions. It is widely agreed that a large fraction of the genomic output of living things …

Lasanius, an exceptionally preserved Silurian jawless fish from Scotland
The fossil record of non‐biomineralizing, soft‐bodied taxa is our only direct evidence of the
early history of vertebrates. A robust reconstruction of the affinities of these taxa is critical to …

Synchrotron-based chemical imaging reveals plumage patterns in a 150 million year old early bird
Charles Darwin acknowledged the importance of colour in the natural selection of bird
plumage. Colour can indicate age, sex, and diet, as well as play roles in camouflage, mating …
