There will be no #GlobalPlasticsTreaty from #INC5.2. The Chair informed us at just after 6am this morning that, despite best efforts and a new revised Chair's text overnight, consensus could not be reached.

Our Viewpoint article in Environmental Science & Technology argues that linking chemical pollution to biodiversity loss in field studies requires careful control of confounding factors—otherwise, “effects” may be spurious.

Non-profit publishers (PLoS, Oxford, Cambridge) and publishers partnering a lot with academia (Wiley) are much more committed to open science than the others - MDPI being the worst by large. (4/5)

Over the past few years, our PlastChem team has worked tirelessly to map the chemical complexity of #plastics. Today, we publish the findings in @nature.com. We hope this evidence propels the development of safer plastics to protect human health and environment. 1/4

📢 NEW PAPER on #Chemicals in #RecycledPlastics! 📢

We collected recycled polyethylene (PE) pellets from small scale mechanical #recycling facilities, measured chemicals leaching out of the plastics into water and impacts in zebrafish.

This is such an important call from an early-career scientist. The current delays in decisions on publications are absolutely damaging to the careers of our junior colleagues. (1) 🧪

Dear editors, your publication delays are damaging our careers

There are already many articles for which there is more attention on Bluesky than on other comparable micro-blogging sites, meaning the academic community and the general public have clearly adopted Bluesky as one of its core places to disseminate and discuss new research.

‘A place of joy’: why scientists are joining the rush to Bluesky Researchers say the social-media platform — an alternative to X — offers more control over the content they see and the people they engage with.: https://www.nature.com/articles/d41586-024-03784-6
