But the four reports of endometrial cancer among the women who took compounded hormones point to how risky they may be. (2015-09-30)

What roundworms can teach us about human growth
Human beings and the roundworm C. elegans have more in common than you'd expect. Thanks to a common ancestor more than 700 million years ago humans and roundworms have a similar hormone to drive and regulate growth. By activating or deactivating this hormone scientists can stimulate or stunt the growth of the worms. This is shown by researchers from the Functional Genomics and Proteomics Group at KU Leuven (University of Leuven), Belgium. (2017-05-03)

Sex hormones hold key to higher rates of abdominal aortic aneurysms in males
Men have a four times greater risk than women of developing abdominal aortic aneurysms, estimated to be the cause of death in 4 percent of people over the age of 65, and University of Kentucky researchers found that removing circulating androgens, including testosterone and dihydrotestosterone, from male mice lowers their risk of aneurysm to that of females. (2005-04-04)

Double-barreled attack on obesity in no way a no-brainer
In the constant cross talk between our brain and our gut, two gut hormones are already known to tell the brain when we have had enough to eat. New research from Sydney's Garvan Institute of Medical Research suggests that boosting levels of these hormones simultaneously may be an effective new weapon in the fight against obesity. While the double-barreled approach may seem like a no-brainer, the strongly enhanced effect seen was by no means inevitable. (2013-07-09)
