Here’s the weekly summary of both new chemistry research and studies that have been in the news. This week features news on why a Canadian town’s water turned pink, how a dual drug combination can be used to kill antibiotic-resistant bacteria, and more. As always links to further articles and original research papers are provided below.

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. Asterisked studies are free but require logging in to read.
