The stinging wasps (Hymenoptera: Aculeata) are an extremely diverse lineage of hymenopteran
insects, encompassing over 70,000 described species and a diversity of life history traits…

In chordate phylogeny, changes in the nervous system, jaws, and appendages transformed
meek filter feeders into fearsome predators1. Gene duplication is thought to promote such …

Chalcidoidea (Hymenoptera) is extremely diverse with an estimated 500 000 species. We
present the first phylogenetic analysis of the superfamily based on both morphological and …

A method is presented for embedding nucleotide sequence data in a simple metric space.
Computer graphical examination of spatially-represented sequences permits rapid searches …

The vertebrate body plan is established during gastrulation, when cells move inwards to form
the mesodermal and endodermal germ layers. Signals from a region of dorsal mesoderm, …

In vertebrates, hematopoietic and vascular progenitors develop from ventral mesoderm. The
first primitive wave of hematopoiesis yields embryonic red blood cells, whereas progenitor …

To facilitate molecular genetic analysis of vertebrate development, haploid genetics was
used to construct a recombination map for the zebrafish Danio (Brachydanio) rerio. The map …

Discovery of antibiotics acting against Gram-negative species is uniquely challenging due
to their restrictive penetration barrier. BamA, which inserts proteins into the outer membrane, …

The use of high-fidelity simulation as an accepted substitute for traditional clinical learning
experiences in nursing education has gained acceptance over the past decade, as evidenced …

The order Hymenoptera (wasps, ants, sawflies, and bees) represents one of the most diverse
animal lineages, but whether specific key innovations have contributed to its diversification …
