Cuttlefish embryos reveal that cephalopod mollusks evolved specialized arms and tentacles by activating the same genetic circuits that control development of limbs in arthropods and vertebrates.

The genome of a tiny tomato pest reveals mechanisms that underlie metazoan genome reduction.

Quantitative analyses of multi-dimensional microscopy datasets with a new Fiji/ImageJ plugin for cell tracking reveal the lineage restrictions and morphogenetic cellular behaviors underlying embryonic limb outgrowth in the direct developing crustacean Parhyale hawaiensis.

A conceptual and unifying framework with a critical appraisal of lipid hijacking by microbes cycling between an arthropod vector and a mammalian host is explored.

Host characteristics drive the assembly of similar communities within the convergently evolved and geographically distant pitcher ecosystems of carnivorous pitcher plants.

Hairless emerged as an evolutionarily novel regulatory protein that replaced an ancestral paradigm of direct co-repressor recruitment by Suppressor of Hairless, its partner transcription factor in the Notch signaling pathway.

CenH3, the defining component of centromeres in almost all eukaryotes, was independently lost in four insect lineages that transitioned from monocentricity to holocentricity.

Sox21b-1 regulates simultaneous formation of anterior segments and addition of posterior segments in a spider, which resembles segmentation in long- and short-germ insects, and suggests SoxB regulation of segmentation is an ancestral feature of arthropods.

A heat exchange mechanism in the head of kissing bugs helps to prevent stress and regulate their temperature while they feed on warm blood.
