Here’s the weekly summary of both new chemistry research and studies that have been in the news. This week features new on how an artificial sweetener can help detect urine in swimming pools, a chemically-tweaked opioid which avoids common side effects in rats, 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.
