DNA viromes yielded more viral populations, and higher-quality genomes, than total soil metagenomes, while RNA viromes matched total metatranscriptomes in recovery and improved only genome quality. Bacteria- and archaea-enriched fractions, eukaryote-enriched fractions, and polyadenylation-enriched metatranscriptomes each captured viruses the other preparations missed, and their host predictions pointed to different kingdoms. https://t.co/ivVe3XNR40
Two-level selection theory for obligate endosymbiosis finds exploitation is the usual outcome: high symbiont numbers per cell, strong symbiont-level selection, horizontal transfer, or fast symbiont mutation all favor selfish symbionts. https://t.co/2MsAjNgVVO
Al menos 13 mexicanos han perdido la vida debido a ataques con misiles estadounidenses dirigidos a presuntas embarcaciones del narcotráfico, de acuerdo con una reciente investigación de Los Angeles Times.
Across 1,211 real shotgun metagenomes, four taxonomic profilers produced different diversity estimates; alpha-diversity conclusions shifted with tool choice, k-mer methods, and database. https://t.co/z3lzFDSYIv
Lightweight probes could make genomic foundation-model embeddings a cheap triage layer for metagenomic biosurveillance, including short-read screening before assembly. https://t.co/iPiC7o1YIr
EE. UU. registra un brote sin precedentes de ciclosporiasis: casi 7 mil casos en 34 estados. Los CDC investigan el origen de la infección, que podría estar ligada a alimentos frescos como lechuga y ensaladas. Taco Bell también es investigado.
#Cyclospora has sickened people across the U.S. While the source remains unknown, past outbreaks have been linked to fresh produce. Food safety starts in the field, where efforts to prevent contamination before harvest can help reduce foodborne illness.

A biology journal trialled paying their reviewers and found it led to faster first editorial decisions – and increased review quality.
