The 2026 Winter Olympics are unfolding in Milan and Cortina, and we can’t look away: We’re watching athletes fly down mountains on skis and glide — sometimes slipping and falling — on the ice. Vikram Chib studies performance and how the brain responds to rewards at Johns Hopkins University. And he says rewards aren’t just for Olympians; they’re baked into basically everything humans do. But those rewards and the pressure that comes with them can come at a cost to people’s brains. And even Olympians are human. Sometimes, we crack. So, today, Vikram dives into the science behind choking under pressure. Interested in more Olympics science?

Picture this: You’re at a pretend tea party, but instead of sitting across from toddlers in tiaras, you’re clinking cups with Kanzi—an ape with the incredible ability to communicate with humans. NPR science correspondent Nate Rott talked to some scientists who did exactly that. But these scientists weren’t just having pretend tea parties with Kanzi for fun, they were trying to test the limits of his imagination – because humans’ ability to play out “pretend” scenarios in our heads and guess at the potential consequences of our actions is key to how we live our lives. And we might not be the only animals to do it!For more of Nate’s reporting, plus videos of Kanzi, check out the full story on NPR here.

Early last year, a hundred researchers, clinicians and other experts on HIV discussed the development of an innovative vaccine that could prevent the disease. But just as the meeting was about to wrap up, the mood darkened. A new executive order signed by President Trump on Inauguration day had frozen all foreign aid, pending a review. Soon, DOGE would begin its decimation of USAID — and with it, this vaccine trial. That is – until the South African researchers came up with a new plan. Read more of freelance science reporter Ari Daniel’s story here.This story was supported by a grant from the Pulitzer Center.Interested in more on the future of science?
