Investigation of meiosis in the nematode Pristionchus pacificus has illuminated evolutionary variation in this essential aspect of reproduction and established a new model for future study.

The more semantically related a later experience is to an earlier one (along multiple dimensions), the more likely humans are to think back to and strengthen the memory of the earlier experience and mentally link the two experiences.

Female meiotic spindles correct trisomy by expelling extra chromosomes into the first polar body.

To maintain genomic integrity during oocyte development, the tumor suppressor BRCA1/BRC-1 and the SMC-5/6 complex both repress intersister crossover recombination events while BRCA1/BRC-1 also specifically inhibits error prone repair of DNA breaks during meiotic prophase I.

A novel form of self-fertility evolved in Cryptococcus depauperatus, a close relative to the human pathogenic Cryptococcus species, in which sexual development is attained by self-signaling of a cognate pheromone and pheromone-receptor pair.

Opposing activities of ATR kinase and PP4 phosphatase balance phosphorylation of the protein DSB-1 to produce sufficient but not excessive amount of DNA double-strand breaks during meiotic prophase in Caenorhabditis elegans.

Cells use two interdigitated biosynthetic pathways that can be regulated independently to produce diverse bioactive sterols.

Meiotic cells employ a specific pathway to limit the amount of gene conversion occuring at recombination sites.
