Long non-coding RNAs (lncRNA) are a type of RNA molecule that do not carry instructions to make proteins. Instead, they influence how other genes are expressed. There are tens of thousands of lncRNAs in the human body, many of which are active in specific tissues or diseases like cancer. However, figuring out exactly what they do has been a major challenge. Now, a team of researchers has found that lncRNAs seem to regulate gene expression in a coordinated manner that had not been seen before.

A new article in Ecological and Evolutionary Physiology examines how the immune system and reproduction interact in female mammals, especially during pregnancy, from mating to birth.

Lauren E. MacDonald, Chloe C. Josefson, Bethaney D. Fehrenkamp, and Teri J. Orr explore how this relationship evolved and its effects on survival in their paper, "Reproductive Immunology from Copulation to Parturition in an Evolutionary and Ecological Context."
