Interesting (and slightly worrying) trends of scientific publications by topic in the USA, normalized to 2010. You see that blue dropping line at the bottom? That's physics. The two most steeply rising ones? Psychology and social sciences.

Many thanks to Mark Macklin and my colleauges for publishing our @ScienceMagazine paper on global river systems affected by metal mining. science.org/doi/10.1126/sc…

Our latest @EnvSciTech paper explores antimony(V) incorporation into schwertmannite. Check it out at: doi.org/10.1021/acs.es…. By M Rastegari @nkarimia @ScottJoh_dirtDr @GeoloJess_ S Doherty @gichem06 M Hosseinpour & myself. Thanks @arc_gov_au @ausynchrotron

This atomic-scale movie upends a 100-year-old theory! Thanks to record-breaking 🔬 video resolution at our @molecularfoundry, scientists have discovered 🔎 how atomic-scale defects direct #nanoparticle growth. Check it out ⬇️ newscenter.lbl.gov/2022/07/26/how…

This article briefly covers essential topics on preparing samples for SEM. If you're new to SEM, or just want to start your Monday with an easy read, I recommend it. Scanning Electron Microscopy: 6 SEM Sample Preparation Pointers for Successful Imaging bitesizebio.com/34150/sem-samp…

Climate change is not our largest environmental problem. We need to get serious about the largest - chemical contamination of soil, water and air crccare.com/news/climate-c…

Our new paper in @EnvSciTech reveals a novel pathway of arsenic release from mining-impacted sites. pubs.acs.org/doi/abs/10.102…. By @gichem06 @Dane37697329 Robert Aughterson & @BurtonEd. Thanks to @arc_gov_au @ausynchrotron @ANSTO

If you're interested in how hexavalent chromium can be reduced via interactions with iron minerals, such as schwertmannite, check out our paper in @HAZMAT_journal. doi.org/10.1016/j.jhaz… By @gichem06 @nkarimia & myself. Thanks to @arc_gov_au @ausynchrotron & NSRRC, Taiwan.

Turning waste from bauxite refining into an environmentally-beneficial resource. Our new paper in @HAZMAT_journal explores the use of Bauxsol from Virotec Pty Ltd for remediation of lead-contaminated soil. Thanks to @arc_gov_au @ausynchrotron. doi.org/10.1016/j.jhaz…

Our new @ACSEarthSpace paper flips a decades-old paradigm by showing that arsenic enhances transformation of schwertmannite to jarosite. doi.org/10.1021/acsear…. @arc_gov_au @ausynchrotron @SCUonline @nkarimia @ScottJoh_dirtDr @vaschoepfer @gichem06 @Dane37697329

@HAZMAT_journal Are root elongation assays suitable for establishing metallic anion ecotoxicity thresholds? I would say it depends. Have a look at the excellent work by Lamb et al. (2021) doi.org/10.1016/j.hazl…

I know a joke about PFAS but it lasts forever

Fully-funded PhD positions are available on @arc_gov_au research into hexavalent chromium formation and fate in #bushfire-impacted soil with our team @SCGeoscience: careers.geochemsoc.org/jobs/13268750/…. Our recent paper gives some background info on the topic: doi.org/10.1016/j.envp…

Professor Chris Bishop demonstrates the reaction of phosphorus burning in pure oxygen, which also explains why the name phosphorus means "bearer of light" [full video with more reactions: buff.ly/2KNlrCQ]

I have been an editor for 6 months now and read about a hundred papers, and this is what I have learnt so far. As an author myself and a publisher of journals where I talked to external editors all the time, here is what we wish we could tell authors, in no particular order(1/n)
