Vanderbilt biologists have localized the seasonal light cycle effects that drive seasonal affective disorder to a small region of the brain called the dorsal raphe nucleus. Read More

It’s a story of love and determination and a debilitating lifelong disorder. A son’s rare genetic disease has led his mom to become a scientist at Vanderbilt University. Watch this VUCast Extra and a mom’s race against time. Read More

Vanderbilt biologists have found a direct link between the biological clock and Angelman syndrome, a neurogenetic disorder that occurs in more than one in every 15,000 live births. The link may provide a valuable way to judge the effectiveness of the first experimental drugs under development for treating the syndrome. Read More

Tricking algae’s biological clock to remain in its daytime setting can dramatically boost the amount of commercially valuable compounds that these simple marine plants can produce when they are grown in constant light. Read More
