Prokaryotic TRADD-N and Death-like adaptor domains in diverse predicted apoptosis and immune systems from multicellular prokaryotes and metazoans indicate the common origin of key apoptosis mechanisms required for the stabilization of multicellularity.
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.

Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.
Exploiting the power of the Fshr reporter, the first comprehensive genetic record of the spatial distribution of FSHR expression offers prospects for extensive exploration of FSH-FSHR biology.
Outgroup conflict can negatively impact general reproductive behaviour, egg investment, and parental care, resulting in decreased reproductive output even in the absence of physical confrontations.

Activation of a piRNA cluster is achieved by high temperature and without maternal inheritance of homologous piRNAs highlighting how variations of species natural habitat can become heritable and shape epigenome.
Aquatic animals cocultured with rice in paddy ecosystems can increase food production, improve nitrogen (N)-use efficiency, and maintain soil fertility by reducing weeds, and promoting recycle and complementary use of N.
A pain-relaying ion channel on a hypersensitive population of sensory neurons can instead elicit sensations of itch in both fish and mice when directly activated, providing a novel model of itch transduction.
The growth environment driven ratio of ATP to growth rate, called absolute growth, determines the final population composition of Staphylococcus aureus and Pseudomonas aeruginosa when in co-culture.
