Forever chemicals: Scientists condemn massive lobbying campaign to alter PFAS definition
In a letter published Tuesday in a scientific journal, a group of 20 researchers warn that 'this effort is politically and/or economically, rather than scientifically, motivated.'

In this issue of Nature Chemistry, I write about the importance of having an online presence that we control ourselves. Since you're all on Bluesky, you're probably already on top of things! Open access sharing link: www.nature.com/articles/doi...

Controlling our online professional persona
Nature Chemistry - Modern scientists exist within the digital world. Shira Joudan describes how an online presence is beneficial to researchers, and what a baseline presence can look like.

Ok, xkcd 😂 imgs.xkcd.com/comics/mass_...
Cartoon with the caption “before the bathroom scale was invented, the only way to weigh people was mass spectrometry”.  Pictures are two people, a launchpad with a magnet hanging from the roof and a target. One person tells the other: “Rub this balloon against your head, then go jump past that magnet toward the target on the wall”

Hey #chemsky and #science Bleeps (?)...the Chemscrapes project page has been updated to include a free download of a massive poster size parafilm PSA poster for your lab www.chemscrapes.net/s-projects-s... While you're there, check out other ChemScrapes projects. Shares appreciated :)
This image is a humorous safety poster likely found in a laboratory setting that uses parafilm. Let's break down its message:

"DON'T BE A LAB FILM TEARAWAY": This headline uses a play on words. "Tearaway" can refer to someone who is badly behaved or rebellious. In this context, it also literally refers to someone who tears off pieces of parafilm instead of using scissors.

Image of the Film Box and Scissors: The poster depicts a cartoonish blue box that likely holds a roll of lab film. It has a happy face, suggesting the film itself would prefer to be treated properly. A pair of scissors is shown cutting the film neatly.

"GIVE YOUR ROLL A SCISSORING TODAY!": This is the call to action, again using playful language. "Scissoring" here means to cut the film with scissors. The word choice is meant to be memorable and a bit cheeky.
