Lecture title: How microbes are rewriting the rules of immunity - Front Row lecture with Howard Hang, PhD Description: How do microbes influence our immune system, and can we leverage this relationship to combat disease? In this free Front Row lecture, Scripps Research Professor Howard Hang will delve into his lab’s innovative work at the intersection of chemistry, microbiology and immunology. By dissecting the molecular dialogues between gut bacteria and human cells, Hang’s research uncovers how microbial enzymes generate small molecules—called microbial metabolites—that can influence immune responses.

San Diego Mesa College Art Gallery is honored to present the first exhibit of the school year: "Clothes Story," envisioned and curated by Atlanta based designer Kenneth Green. This exhibition celebrates the lives and contributions of African American women by carefully replicating over thirty garments and fashion accessories that represent what women wore in historical periods ranging from 1890 to 1963. Every dress, coat or cloak in Clothes Story has a unique story to tell, whether revealing details about the maker, providing information about the historical context or teaching us about the person who wore it. Through fashion, the narratives shared in this exhibition come alive. The engaging display takes the viewer on a journey through time, inviting them to experience women’s lives at home and in their communities and capturing historical moments that showcase the African American female experience and acknowledge their resilience, strength, bravery, courage, and unapologetic spirit for change. With appreciation to The Hervey Family Fund at the San Diego Foundation whose generosity helps illuminate these stories. The exhibition is presented in collaboration with the San Diego African American Museum of Fine Art. Join us for the reception on Saturday, September 6, 4 p.m. – 7 p.m. Exhibition is on view from August 25 to October 16, 2025. Gallery Hours: M, T, W, TH, 12 p.m. - 5 p.m. (Or by appointment.) Closed Fridays, Weekends & Holidays. Clothes Story Exhibit on Instagram San Diego Mesa College Gallery on Facebook / Instagram
