The University of Delaware’s Osher Lifelong Learning Institute (OLLI) will offer more than 30 free live-online mini-courses for adults 50 and over, Jan. 14-24.

The January Explorations series is presented by OLLI’s volunteer instructors and covers topics in art, nature, history, current events, literature, health and more. The online series is free and open to the public. OLLI membership is not required.

“We are delighted to invite the public to experience examples of the breadth of OLLI’s courses,” said Karen Asenavage Loptes, UD OLLI director. “Our OLLI members know that learning is just one part of an enriching experience that also includes social events, extracurricular activities and travel opportunities.”

The January sessions include several health-related courses, among them, “How the Brain Ages” exploring normal brain changes and how to minimize the effects of aging, presented by Dr. Michael Salvatore, a retired pulmonology, critical care and palliative care physician.

“Desegregation of Schools: Myth or Reality,” one of several history courses, is led by longtime public education advocate Bebe Coker, examining the impact of desegregation on public education, housing, employment and more, asking whether education was genuinely desegregated, or just school buildings.

Veteran instructor Tom Powderly will lead multiple entertainment-related courses including “Just in Time: Music Across the Years,” about themes that have inspired songwriters in multiple genres.

The Zoom-based courses are free, but registration is required.

In addition to January Explorations, OLLI offers over 300 courses each spring and fall in Dover, Lewes, Newark, Ocean View, Wilmington and online. Spring registration begins Jan. 3, and classes start Feb. 3.
