The brown bullhead catfish's mealnoma is the first transmissible cancer identified in fish or in freshwater environment (only one of 4 known to date). How many more of these transmissible cancers are out there an undiscovered? #fishgen 🧬 Also, check out this great write in the @nytimes.com

Thanks @luohaoxu.bsky.social for presenting at #WGDip’s science forum. Using snow carp as a model, he argued that chromosome fusions often initiate rediploidisation after autopolyploidy. Featuring a haplotype-resolved assembly with 443 chromosomes (20n!) & insights into polyploid sex determination.

A large-scale analysis of wildfires in the Western United States shows that U.S. Forest Service fuel-reduction treatments not only curb fire spread and intensity, but also, for each dollar invested, generate more than three times the value in avoided damages. Learn more: https://scim.ag/4uAs5Qc

Wildfires are among the most pressing environmental challenges of the 21st century, intensified by the accumulation of forest fuels after a century of fire suppression policies. Although fuel-reductio...

Our new paper doi.org/10.1098/rspb... on long-term genetic threats to small populations finds that "mutational meltdown" (bad mutations fixing) is less of a problem than "mutational drought" (too few good new mutations) @wmawass.bsky.social @uliseshmc.bsky.social @jeremyjberg.bsky.social 1/5
