GTSF1 is an essential activating cofactor for PIWI proteins in many metazoans. In the nematode Caenorhabditis elegans, however, GTSF-1 does not bind PIWI, but is associated with the RNA-dependent RNA ...

Researchers worry that generative AI is homogenizing culture and cognition.

Spillwords.com presents: Ammonite, a poem written by Peter Sarkies, a Biochemist based at the University of Oxford, UK.

Top predators drive changes in ecosystem structure. For the last ~370 million years, large-sized vertebrates have dominated the apex of the marine food chain, while invertebrates have served as smalle...

piRNAs are an important genome regulatory mechanism conserved across metazoans. In the nematode C. elegans, piRNA biogenesis evolved several differences from other metazoans. Beltran et al. study the ...

piRNAdise lost: piRNAs, a key component of the defense against transposable elements appeared very early in animal evolution. Remarkably however, they have been lost multiple times independently in d...

Epigenetics is fundamental to cell differentiation as it enables cells with identical genomes to adopt distinct fates. Some epigenetic information can also be transmitted between generations, in a pro...

De-extinction critiques focus on animal welfare, ecosystem disruption, threats to traditional conservation, and anxiety about human hubris. Respondents argue that humanity is obligated to reverse dama...
