Analyzing every marijuana-related Twitter message sent during a one-month period in early 2014, researchers at the School of Medicine have found that the “Twitterverse” is a pot-friendly place. In that time, more than 7 million tweets referenced marijuana, with 15 times as many pro-pot tweets sent as anti-pot tweets.

Using Washington University’s state-of-the-art zebrafish facility, scientists have identified a gene that helps regulate how well nerves of the central nervous system are insulated. The finding may have implications for human diseases such as multiple sclerosis, in which this insulation is lost.

It’s normal for a young child to have tantrums and be otherwise disruptive, but researchers have found that if such behavior is prolonged or especially intense, the child may have conduct disorder, a childhood psychiatric problem that could be a harbinger of antisocial behavior. The research was led by Joan L. Luby, MD (shown).

Weikai Li, PhD, assistant professor of biochemistry and molecular biophysics at Washington University School of Medicine in St. Louis, has received a two-year, $143,000 grant from the American Heart Association for research titled “Mechanism of VKOR Function and Warfarin Inhibition.”
