Welcome to the Saturday edition of The Conversation U.S.’s daily newsletter.

Jimmy Swaggart, a televangelist whose popularity peaked in the 1980s with his fire-and-brimstone sermons, died on July 1 at the age of 90. At its apex, a television ministry he launched reached millions in some 140 countries, including Peru, the Philippines and South Africa.

Thanks in part to the $150 million raised annually from a mail-order business, Swaggart lived a lavish lifestyle until sex scandals tarnished his reputation.

But his legacy survives, explains Diane Winston, a religion scholar at the USC Annenberg School for Communication and Journalism. “Swaggart’s calls for a return to conservative Christian norms live on – not just in Sunday sermons but also in today’s world of tradwives, abortion restrictions and calls to repeal gay marriage,” she writes. According to Winston, Swaggart’s music lives on, too: The day before he died, the Southern Gospel Music Association Hall of Fame inducted him as a member. And his old services and Bible studies are also streamed daily on his network.

This week we also liked articles by researchers who have studied dunes on Mars, independent pizzerias in Gainesville, Florida, and muscle loss in cancer patients.
