An analysis of Twitter hashtag use on the subject of diabetes provides new insights about spreading health information through social media. The study, led by Jenine Harris, PhD, assistant professor at the Brown School at Washington University in St. Louis, looked at the hashtag #diabetes and its interaction with two Twitter measures of engagement, retweeting and favoriting. The study found retweeting and favoriting was significantly lower for tweets about the number or percentage of people with diabetes, while favoriting was higher for tweets about health problems associated with diabetes.

Cholesterol also is a building block of steroids and hormones, including those that trigger puberty and support pregnancy. A new study, led by Daniel Ory, MD, implicates a surprising regulator of cholesterol in cells’ ability to make these hormones, especially in tissues associated with fertility, such as the ovaries.

Brain tumor stem cells can resist treatment and regrow tumors, but scientists have identified a vulnerability in these cells that could lead to a new approach in battling deadly brain tumors.
