• The Iguanas That Rafted To Fiji

  Most iguanas are indigenous to the Americas. So how did the Fijian species end up on the island, nearly 5000 miles away in the South Pacific? According to a new study in the journal PNAS, it was probably via raft ... that is, on clump of floating trees. And this rafting hypothesis isn't entirely unprecedented. After hurricanes Luis and Marilyn hit the Caribbean in the 1990s, researchers found that a group of iguanas had floated over 180 miles away from Guadeloupe to the territory of Anguilla.

• Is AI Ready For Robots?

  It seems like artificial intelligence is everywhere in our virtual lives. It's in our search results and our phones. But what happens when AI moves out of the chat and into the real world? NPR science editor and correspondent Geoff Brumfiel took a trip to the Intelligence through Robotic Interaction at Scale Lab at Stanford University to see how scientists are using AI to power robots and the large hurdles that exist for them to perform even simple tasks.Read Geoff's full story.

• Rare Narwhal Footage Shows New Tusk Activities

  What are the narwhals up to? Generally, we don't really know! They are mysterious creatures. NPR science correspondent Nell Greenfieldboyce talks about new, rare drone footage scientists captured of arctic narwhals. The video sparked new ideas for how they use their tusks.Read Nell's full piece.Love mysterious critters and want to hear more?

• The Algae That Thrive in Arctic Darkness

  Microalgae are tiny organisms that convert energy from sunlight into fuel. The arctic ecosystem depends on them. In springtime, the algae bloom brilliant shades of green and draw tiny crustaceans, fish, birds and more to arctic waters. But what happens in wintertime, when the sun goes down and darkness reins for months? In the depths of the polar night, biogeochemist Clara Hoppe has found evidence that some microalgae are still ready to photosynthesize. Today on the show: how tiny microalgae limbo for their lives and come out more powerful than scientists ever imagined.

• Climate Change + Baseball = More Home Runs

  Baseball season is nigh! From Yankee stadium in New York to Dodger stadium in Los Angeles, teams around the country will face off Thursday to mark the start of the 2025 MLB season. And when we here at Short Wave think of baseball, we naturally think of physics. To get the inside scoop on the physics of baseball, like how to hit a home run, we talk to Frederic Bertley, CEO and President of the Center of Science and Industry, a science museum in Columbus, Ohio. In this encore episode, he also talks to host Regina G. Barber about how climate change is affecting the game.Interested in the science of other sports?
