This Week in Chemistry – Dinosaur Feather Pigments, & Elephant Seal Mercury

15-09-13 - This Week in Chemistry

Here’s the weekly summary of both new chemistry research and studies that have been in the news. This week features research on melanin pigments found in a dinosaur fossil, a method that uses infrared spectroscopy to assess the degradation of old cassette tapes, and more. As always, links to further articles and original research papers are provided below, as well as further studies of interest not included in the graphic.

Note: links to studies behind a journal paywall are indicated with (£). Studies without this symbol are open access, and can be accessed and read for free.
