NATURE'S FEAR FACTOR
WEDNESDAY, SEPTEMBER 14, 9:30 PM

For animals in Mozambique’s Gorongosa National Park, the normal balance of competition and predation was upended when a war wiped out the top predators. The remaining animals didn’t simply grow in numbers — they began behaving in unusual ways, veering outside their typical territories and feeding patterns.

ENDING HIV IN AMERICA
WEDNESDAY, SEPTEMBER 21, 8 PM

Almost 40 years after the discovery of HIV, could we be on the verge of ending the AIDS epidemic in America? As of 2019, there were only 34,000 new cases of the disease in the U.S. — a feat that once seemed near-impossible to achieve. How did scientists and the public health community tackle one of the most elusive deadly viruses to ever infect humans? Can innovative drugs bring new infections to zero? This is the story of incredible scientific achievement and the public health work that still needs to be done to end HIV in America.

CUBA'S CANCER HOPE
WEDNESDAY, SEPTEMBER 21, 9 PM

Cuban scientists were forced to get creative when the U.S. trade embargo left Cuba isolated from medical resources. Now they’ve developed lung cancer vaccines that show so much promise, some Americans are defying the embargo and traveling to Cuba for treatment. In an unprecedented move, Cuban researchers are working with U.S. partners to make the medicines more widely available.
