Intraspecific predator interference enables a wide range of consumer species to coexist with a limited variety of resources, explaining the paradox of the plankton and species diversity patterns across ecosystems.

Large eyed bull ants are able to use the exceedingly dim lunar polarised light pattern in the overhead sky to navigate back to the nest at night.

In nematode worms, NSUN-1 methylates ribosomal RNA and influences phenotypes related to aging, stress resistance, germ line development, and cuticle integrity by regulating translation of specific mRNAs.

The capacity for symbiosis between photosynthetic microalgae and early diverging lineages fungi was demonstrated with microscopy and stable isotope exchange of carbon and nitrogen.

Although complete mouse in vitro spermatogenesis can be achieved, failure of adult Leydig cell development, with accumulation of progesterone and estradiol, androstenedione deficiency, deregulation of steroidogenic, and steroid target gene expression, were highlighted in organotypic cultures, even with hCG.

Primary cilia of neural crest-derived cells mediate Indian hedgehog-induced signal transduction in the periocular mesenchyme and are required for normal anterior segment development.

The fly connectome reveals dedicated cell types for processing specific kinds of visual information such as color or skylight polarization.

The same host–virus interactions can evolve multiple times in nature, due to the high effective mutation rate of viruses, and provide interesting systems of study.

An analysis of the first complete synaptic resolution connectome of Drosophila's navigation circuit uncovers neural network motifs supporting broadly relevant sensorimotor computations.

Sonic Hedgehog is transported inside cytonemes with co-receptors that promote contact-mediated signal delivery to initiate rapid, receptor-dependent responses in recipient cells.
