This important study reports that two distinct waves of ovarian follicles contribute to oocyte production in mice. The paper provides large amounts of data that will benefit future studies, although ...

Analyses of zebrafish meioc mutants revealed that spermatogonial stem cells with low rRNA transcription caused by nucleolar Piwil1 require Meioc to keep Piwil1 in cytoplasm for the upregulation of ...

The nucleolus is where ribosomal RNA (rRNA) is transcribed, processed, and assembled into the building blocks of ribosomes, the molecular machines that make proteins. Researchers discovered that rRNA ...

Several groups hope to develop artificial-intelligence models that can predict how cells behave.

A previously unknown structure discovered in our cells could pave the way toward new treatments for various genetic disorders. The existence of the organelle—which has been dubbed the ...
