I'm thrilled to see this paper out, which I co-led with @DitchOntologist, and featuring input from loads of excellent co-authors. It's our interdisciplinary perspective on ditches; what they do, why they matter, and how we should look after them. nature.com/articles/s43247-0…

Our new paper is out in Nature: “Nanoplastic concentrations across the North Atlantic”. An estimated 27 million tons of #nanoplastics were found, even at depths over 4500 m. Huge thanks to my brilliant MSc student Sophie and the sampling support from NIOZ! doi.org/10.1038/s41586-025-0…

It took me SEVEN years to figure out that you can save a ggplot as a vectorized .svg file ggsave("file.svg"). The svg file can be opened on powerpoint and it will be completely vectorized, even text are still recognized as text boxes! No more recreating plots on illustrator!!!!!
