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 🧪

This MOF offers a PFAS twofer: sensing and removal

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...

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...

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)

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.

Remember when you first learned about genetics at school? All those fascinating examples of human traits that are each apparently determined by just a single gene? Time to check in on some of your favourites to see how they’re doing. 🧬🧵🧪 1/n

Four images to illustrate some prominent single-gene myths. Top left shows a photograph of a person deftly rolling their tongue into a U-shape. 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.

Measure the salamanders

Measure them all

Dr Mark D. Scherz @markscherz.bsky.social · Mar 28

Blown away by this paper on body size variation among 11,264 (!!!) measured plethodontid salamanders over an elevational gradient. Super surprised to see that it is not temperature that has the main explanatory role, but mostly humidity and precipitation 🧪🦎
onlinelibrary.wiley.com/doi/full/10....

The Structure Equation Model (a fancy kind of Path model) from the paper, constructed of four factors influencing body size: elevation, which acts indirectly via its effect on temperature and precipitation; temperature, which acts directly only weakly, but more strongly via a direct effect on humidity; precipitation, which acts directly on body size but also has a significant relationship with humidity; and humidity, which has a direct influence. It's an elegant figure. There's a salamander representing body size, illustrated by one of the coauthors, Fleming.
