Farmed oysters may boost New York's dwindling wild populations
Farmed oysters may boost New York's dwindling wild populations Lisa Lock Scientific Editor Andrew Zinin Lead Editor Farmed oysters are mixing with and potentially adding to populations of wild oysters—a once-abundant species in New York's estuaries and rivers that has declined drastically over the last century. A new study, published in the journal Molecular Ecology, offers genetic evidence and the first documented proof that farmed eastern oysters are adding to and breeding with wild...
Evidence for a Functional Proximity Law in Multilayer Networks
arXiv:2604.23639v3 Announce Type: replace Abstract: Hub importance scores in multilayer networks persist more strongly between functionally similar layers than dissimilar ones. We call this the Functional Proximity Law and test it across 31 pre-registered experiments: 13 canonical domains (10 confirmed, 3 denied; molecular biology, neuroscience, computer systems, ecology, linguistics, AI architecture) plus 18 pre-registered external and replication validations (15 confirmed, 1 denied, 2...
Ohio wall lizards overcame genetic bottleneck through rapid population boom, genomes reveal
Ohio wall lizards overcame genetic bottleneck through rapid population boom, genomes reveal Andrew Zinin Lead Editor Non-native wall lizards living in Cincinnati, Ohio, have thrived against the odds thanks to an ability to expand their population more quickly than any inbreeding-amplified harmful genes could weaken their chances for survival, new research suggests. An estimated 10 of these European common wall lizards arrived in southwest Ohio in the 1950s, brought home by a boy who smuggled...
Gene ancestries reveal diverse microbial associations during eukaryogenesis
Abstract The origin of eukaryotes remains a central enigma in biology1. Continuing debates agree on the pivotal role of a symbiosis between an alphaproteobacterium and an Asgard archaeon2,3. However, the nature, timing and contributions of other potential bacterial partners4,5,6 and the role of interactions with viruses7,8,9 remain contentious.
Rational engineering of facultative anaerobiosis enables commensal survival in the oxygenated gut
Life originated in the absence of oxygen. Despite its substantial energetic advantages, many modern microbes remain obligate anaerobes, confined to anoxic niches such as the mammalian gut. Why these organisms cannot tolerate oxygen has remained unresolved for more than two centuries.
Genomic hallmarks of parasexual reproduction in three hybrid groups of the human pathogen Cryptococcus neoformans
Hybridization is a major driver of fungal evolution, yet knowledge of the molecular mechanisms underpinning hybridization and its genomic impact remain limited. Here, we analyse 197 Cryptococcus neoformans genomic sequences, including 13 newly sequenced strains, identifying three genetically clustered and distinct hybrid groups (H1, H2 and H3) each with unique parental origins and ecological associations. Using phylogenomics, population structure analyses, and long-read genome assemblies, we...
Mos-Gen: A Generative Molecular Framework for Mosquito Insecticide Design
Announce Type: new Abstract: Mosquito-borne infectious diseases cause more than 700000 deaths worldwide each year. The long-term use of conventional chemical insecticides has induced serious resistance problems, creating an urgent need to develop novel, highly effective, and ecologically sustainable alternatives. While existing artificial intelligence approaches in this domain have focused primarily on activity prediction and classification, they leave a critical gap in the de~novo...
Developmental genetic response of the zooplanktonic tunicate Oikopleura dioica to marine noise pollution.
Background: Anthropogenic noise is an emerging threat to marine ecosystems, yet its effects on marine invertebrates, particularly zooplanktonic species, remain poorly understood. Despite increasing evidence of behavioral and physiological impacts in invertebrates, the effects of noise on embryonic development and the molecular mechanisms underlying acoustic responses remain largely unexplored. Here, to address this gap, we investigated the impact of high-intensity underwater noise exposure...
A 5.3-million-year-old deep-sea whale necropolis in the Diamantina Zone
Abstract Whale falls are biodiversity oases at seabeds1,2,3,4,5,6, yet their record from the oceans has remained sparse and fragmentary6,7. Here we report the discovery of a vast whale necropolis in the Diamantina Zone (4,616- to 7,001-m depth), extending about 1,200 km along the sea floor of the southeastern Indian Ocean. This area has a deep and extensive accumulation comprising five modern natural whale-fall communities and 476 fossil cetaceans recorded.
From hybrids to 'virgin birth,' stick insects reveal stepwise loss of sex
From hybrids to 'virgin birth,' stick insects reveal stepwise loss of sex Lisa Lock Scientific Editor Robert Egan Associate Editor The evolution of sex remains one of biology's greatest puzzles. While sexual reproduction dominates across the animal kingdom, scientists still debate why it persists despite its high costs. Even more mysterious is the loss of sex in favor of asexual reproduction whereby females give birth to copies of themselves without any contribution from males.
