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.

#PlasticsTreaty

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)

Mapping the chemical complexity of plastics - Nature An inventory of 16,325 known plastic chemicals, including >4,200 hazardous compounds, supports the development of safer plastics.

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

Effects of leachates from black recycled polyethylene plastics on mRNA expression of genes involved in adipogenesis and endocrine pathways in zebrafish embryos Black recycled polyethylene pellets were collected from India, Nigeria and Taiwan. These pellet samples were used to create water leachates (in zebraf…

📢 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.

Dear editors, your publication delays are damaging our careers Chia-Hsuan Hsu waited 18 months before chasing an editor for a decision on a paper. The answer surprised him.

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) 🧪

AI-driven approach reveals hidden hazards of chemical mixtures in rivers Artificial intelligence can provide critical insights into how complex mixtures of chemicals in rivers affect aquatic life—paving the way for better environmental protection.

AI techniques can identify harmful chemical mixtures in rivers, enhancing environmental protection by revealing their effects on aquatic life, such as water fleas, even at low concentrations. doi.org/g8wjzd

‘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

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.

Comprehensive Sequencing of Environmental RNA from Japanese Medaka at Various Size Fractions and Comparison with Skin RNA Environmental RNA (eRNA) is emerging as a non-invasive tool for assessing the health of macro-organisms, but key information on its origin and particle sizes remains unclear. In this study, we perform...

Our preprint is out now.
We examined environmental RNA (eRNA) profiles at variousize fractions, released from Japanese medaka! Our results should be useful in optimization of eRNA collection methods.
