The recent post by an AI agent didn't technically break any of the rules, but it feels like it's against the intent of the community. Upvote for YES. Downvote for NO.

Rule 6 states "No US politics", but methinks this is kinda grey on that one.

Upvote this post if you think we should allow posts in AskLemmy.world on the current situation in Iran (provided they don't clearly break the existing rules), and down vote if you think they should be banned.

The impact that wiped out the dinosaurs also wiped out all songbirds, except for in (ark) Australia. Australian songbirds then spread out to rest of the planet.

The closest living descendents (aka basal lineages) are the Lyrebird and the Rufus scrub bird. The lyrebird's song is a mixture of its own song and other birds songs. They have been also been known to mimic chainsaws, car alarms, camera shutters, and human speech.

For those who aren't familiar with the term, it means believing something that probably shouldn't be believed, or being influenced to believe something that's not necessarily in your best interests.

Abstract

Many “smart” and “fitness” watch bands are advertised to contain fluoroelastomers, a type of synthetic rubber designed to be resilient against skin oils and sweat. Fluoroelastomers, which are considered a polymeric form of per- and polyfluoroalkyl substances (PFAS), have historically involved the use of shorter-chain PFAS as surfactants in the polymerization process. In this study, 22 watch bands were analyzed across numerous brands and price points for the presence of PFAS. Products were first screened for total fluorine using particle-induced gamma-ray emission spectroscopy on the surface of these bands, and 15 of the 22 watch bands contained total F concentrations >1% fluorine, suggesting the widespread use of fluoroelastomers in this product category. Watch bands then underwent solvent extraction and targeted LC-MS/MS analysis for 20 PFAS. Perfluorohexanoic acid (PFHxA) was the most frequently detected compound with concentrations from <LoD to 16662 ng/g. A subset of six watch bands also underwent direct total oxidative precursor (dTOP) assay to determine the presence of PFAS precursors. The very high concentrations of PFHxA readily extractable from the surfaces of fluoroelastomer watch bands, together with the current limited knowledge on the dermal absorption of PFHxA, demonstrate the need for more comprehensive exposure studies of PFHxA.

Hi Everyone,

We are looking for another person to help out moderating AskLemmy. Home instance does not matter, and Accounts will need to have a history of positive contribution to Lemmy.

DM or reach out via Matrix if interested.
