My 8th grade son discovered “Rate my professor” today and gave me a rating based on the lectures he’s attended while sick or on vacation.

Yes.

Never seen a more compelling endorsement for submitting your work to GENETICS @genetics-gsa.bsky.social

Alternative Vertebrate and Invertebrate Model Organisms Show Similar Sensitivity as Rodents to a Diverse Set of Chemicals Current regulations aimed at safeguarding human health and the environment from chemical risks require toxicity testing, while regulatory bodies worldwide are phasing out the use of protected animals. Here, we systematically produced toxicity data from five alternative nonmammalian model organisms and a human cell line to demonstrate similarities and differences among distantly related species in their responses to chemical exposure (concentration range 1.8 pM to 2.1 M). We show that Daphnia magna and Danio rerio embryos are affected by more chemicals than Xenopus laevis embryos, Drosophila melanogaster and Caenorhabditis elegans. Lethality/immotility data assembled 72 diverse chemicals into 11 clusters, revealing species-specific outcomes and showing differential enrichment of the clusters for certain chemical structures and modes of action. The ranked relative toxicities of chemicals across the model organisms were highly correlated (Spearman’s correlation, maximum rho = 0.86, p-value = 0; minimum rho = 0.57, p-value = 0.000312), and their average toxicity values closely matched published values for rodents (rat: rho = 0.88, p = 2.8e-06; mouse: rho = 0.88, p = 2.7e-06). Our findings suggest that chemical toxicity under standardized experimental conditions is broadly conserved across a phylogenetically diverse set of model organisms, providing a conservative estimate of mammalian toxicity.

Want to know if the toxicity of a chemical is shared between flies and humans (as well as worms, fish, Daphnia, and Xenopus)? Take a look at our latest paper from the PrecisionTox consortium!

Meet Madhulika Rai, member of the Early Career Scientist Career Development Subcommittee! 👋 She studies how metabolism and growth pathways drive disease using Drosophila and is passionate about mentoring, science communication, and supporting postdocs. Read her spotlight: buff.ly/S3yACCB

In the most surreal Drosophila abstract submission day of my career, Thom Kaufman is submitting a poster abstract based on his work in my lab. Be sure to attend #Dros26 in Chicago and ask Thom to walk you through his poster on slgA and proline metabolism.

LETTER FROM THE EDITORS: IU has now fully cut IDS print. What more is there to say? The decision came hours after IU terminated Director of Student Media Jim Rodenbush.

FlyBase funding squashed amid Harvard grant terminations The team behind the Drosophila genetics database is now requesting donations from labs to keep the resource afloat.

FlyBase, a crucial resource for drosophila research, has lost its funding because its grant is awarded to Harvard. The team is scrambling to find other sources of funds, including donations from labs. Read more: www.thetransmitter.org/community/fl... @flybase.bsky.social

We decided to make these available now instead of waiting for a more in depth publication. Feel free to use - happy to distribute. Both alleles were deposited in BDSC and will be available for order soon.

For my fly colleagues interested in oncometabolites or links between metabolism and chromatin modifications, we generated two Crispr alleles in D2hgdh. Description can be found here:
