Findings provide better understanding of thyroid hormones' role in mammalian seasonal changes

Researchers now have a better understanding of the role that thyroid hormones, the tissues that produce them, and the biochemical pathways on which they act have in driving seasonal reproduction in some mammals, and how this new information may help explain seasonal changes in metabolism and mood that affect humans.

Risk of pneumonic plague epidemic in Madagascar spreading to other nations is limited

Mathematical models have proven the risk of the on-going pneumonic plague epidemic in Madagascar spreading elsewhere in the world is limited, with the estimated number of exported cases staying below 0.1 person in each country between August 1 and October 17.

Treatment of abnormal vaginal microbiota prior to embryo transfer may improve reproductive outcomes

High levels of two specific vaginal bacteria (Atopobium vaginae and Gardnerella vaginalis) serve as diagnostic markers of an abnormal vaginal microbiota that might cause impaired implantation and subsequent poor reproductive outcome.
