Atul Gawande, the staff writer and public-health expert, talks with David Remnick about the progress of the vaccine rollout, the new strains of the coronavirus, and whether we will ever take our masks off. And the actor Daniel Kaluuya talks about playing a man many regard as a martyr, in the new film “Judas and the Black Messiah.” Kaluuya stars as Fred Hampton, a young leader in the Black Panther Party, who was shot in his bed by Chicago police in a predawn raid. The actor talked with Kai Wright, the host of WNYC’s “The United States of Anxiety,” about how the F.B.I. and many whites saw Hampton’s affirmation of Black people as tantamount to terrorism.
