How does chemistry shape the oceanโs iron cycle?
In our new study, we show that the chemical diversity of organic matter controls how iron is stabilized or lost in the subsurface South Pacific Ocean.

Breaking news: The Environmental Protection Agency has ordered scientists in at least one of its research offices to immediately pause almost all research and stop publishing their studies.
Academic authors, here's a peek into the black box of journal publishing from an journal editor if you can bear it:

I now also have a (work in progress) list of #DataViz specific resources as well!

You can find links to tools, papers, books, blogs, and websites that are related to data visualisation. I'll be adding more resources soon ๐

"Exclusive: Medical journal rejects Kennedy's call for retraction of vaccine study"
Beautiful blog post by @hectorsocas.bsky.social where he argues that the โalien shipโ idea for 3I/ATLAS is an example of poor scientific reasoning: post-hoc coincidences, cherry-picked data, and unfalsifiable claims. On the contrary, useful science requires predictive, testable hypotheses.
โSimple explanations are often compelling & convincing but not always accurateโ

I wrote about the Keeling Curve โ our most iconic COโ time series โ for @sfchronicle.com.
"The Keeling Curve is valuable to science, but it is also a treasure that belongs to humanity as the most poignant indication of our impact on the environment and as a testament to our ability to document it."

Barplot showing the adsorption capacity of PLA (in micrograms of Cr per gram of PLA) as a function of the initial redox state of Chromium and the PLA state (pristine, humic-coated, tannic-coated, humic in solution, tannic in solution or UV-aged). Source: own
Hereโs the graphical abstract summarizing our work.
What do you think about biodegradable plastics as tools for pollution mitigation? Letโs discuss! ๐
#ScienceCommunication
๐ก Why does this matter?
Biodegradable plastics, like PLA, arenโt just "eco-friendly"; they can also transport pollutants or, potentially, act as tools for environmental remediation!
More details in the original paper: authors.elsevier.com/a/1kRgUB8cd4...
#Plastics #PollutionControl
๐ Tannic acid stands out:
Reduces Cr(VI) to less toxic Cr(III)
Boosts adsorption significantly
These findings help us understand the risks of microplastics in aquatic environments and their potential applications in pollutant mitigation.
#Environment
๐ Key insights:
1๏ธโฃ UV-aging increases chromium adsorption:
- Cr(III): 60x
- Cr(VI): 15x
2๏ธโฃ Organic matter (e.g humic & tannic acids) facilitates redox reactions, affecting Cr adsorption. Its effect depends on whether it is dissolved or as a surface coating.
#Nanotechnology
๐งช How do biodegradable microplastics interact with toxic metals?
Our latest study explores the role of photooxidation and organic matter in chromium adsorption by PLA (polylactic acid) in water. A ๐งต:

Hi, I'm Carlos Rey-Castro, I am professor at UdL and AGROTECNIO research center (Spain). My personal website is carlosreycastro.github.io and my ORCID is orcid.org/0000-0002-92.... I was unsure about the most adequate list so I also asked the Geosciences feed. Sorry for double requests!

If Bluesky seems dead or low activity on your end it might be that you haven't yet made the most of its design. It's different from Twitter in some key ways so you have to interact differently. I'm writing these tips below from my non-techy perspective, techies please weigh in if I get things wrong:
