Parasitoid wasps have evolved yolkless eggs in many species. However, the genomic changes underlying this trait loss remain poorly understood. Comparative genomic analysis of 64 hymenopteran insects ...

We developed a strategy to identify gut bacteria functionally linked to the development of multiple sclerosis (MS). To minimize confounders, we analyzed microbiota composition in a large cohort of ...

Birds are charismatic—well loved, and highly studied. Many new phylogenies elucidating avian evolutionary relationships are published every year. We have united phylogenetic estimates from hundreds of ...

Knowledge of plant rooting depth is critical to understanding plant-mediated global change. Earth system models are highly sensitive to this particular parameter with large consequences for modeled ...

Identification of the lydiamycin biosynthetic gene cluster in a plant pathogen guides structural revision and identification of molecular target ...

A plant CLE peptide and its fungal mimic promote arbuscular mycorrhizal symbiosis via CRN-mediated ROS suppression ...

The egg-laying monotremes have played a central role in our understanding of mammalian evolution, but their fossil record is poor and their evolutionary history is controversial. Living monotremes are ...

Plants adapt root and shoot development to environmental cues through systemic signaling pathways. In white lupin (Lupinus albus), we identified mutants with excessive cluster roots that also ...

Mammals are diploid creatures. Every cell in their body contains two sets of chromosomes, one from the mother and one from the father. Mouse embryos with only paternal genomes can not develop to term, ...

Meiotic recombination is an evolutionary-conserved process that shapes genetic variation in most eukaryotes. DNA is packaged into nucleosomes, and high levels of nucleosome occupancy suppress ...

Koh et al. show that 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is pathologically elevated in human and mouse Alzheimer’s disease (AD), traumatic brain injury (TBI), and aging, with 15-PGDH ...
