This MOF offers a PFAS twofer: sensing and removal Modified metal-organic framework glows when it captures perfluorooctanoic acid

With a few chemical tweaks to a known metal-organic framework (MOF), researchers have developed a material that quickly detects and removes a common per- and polyfluoroalkyl substance (PFAS) from contaminated water. cen.acs.org/environment/... #chemsky 🧪

Gene loss associated with plasticity-first evolution in Heliconius butterflies Phenotypic plasticity occurs when a genotype can produce more than one phenotype under different environmental conditions. Genetic accommodation allows plastic phenotypes to be tuned to new environmen...

Very excited about this paper led by Erika Castro. She has shown that Heliconius were ancestrally plastic in how they acquired their cyanogens, but some species have lost the ability to biosynthesise toxins, and have lost genes involved www.biorxiv.org/content/10.1...

Structural dissection of ergosterol metabolism reveals a pathway optimized for membrane phase separation The metabolism of ergosterol shapes this lipid to allow the formation of fluid membrane domains in yeast cells.

Out today, we report how small chemical modifications in the metabolism of ergosterol are needed for yeast membranes to phase seperate into ordered yet fluid domains www.science.org/doi/10.1126/... (1/n)

Top right shows a photograph of a person’s ear, highlighting the shape and features of the earlobe and cartilage. Bottom left shows a close-up photograph of a person’s eye, with a vivid blue colouration. Bottom right shows a photograph of a person poised to write with their left hand on the blank white page of a spiral-bound notebook.

Published an op-ed for @cnn.com: “Nobel laureate: I owe America my success. Today, its scientific future is in danger.”
A personal reflection on what’s at stake as science funding gets slashed. I’d be grateful if you could amplify both in and beyond the science world.
