Big Picture Science for Feb 24, 2025: The Latest Buzz









Big Picture Science: The Latest Buzz

REPEAT
Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and how can it be reversed.

Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds.

We investigate the small and the many on “The Latest Buzz.”

Big Picture Science for Feb 17, 2025: Skeptic Check: Into the DeepSeek









Big Picture Science: Skeptic Check: Into the DeepSeek

When the Chinese developer of DeepSeek released its model R1, a rift opened up in Silicon Valley. The company, a relatively unknown player, appeared to have created a better and cheaper model than its American competitors. Some big voices in the tech world called it a “Sputnik moment.” Others worried that the open-source model would allow malicious actors to harness the power of this AI technology. But did the arrival of DeepSeek significantly change how artificial intelligence will unfold? We explore that question and ask whether one particular sci-fi franchise got it right when portraying our anxiety about runaway AI.

Big Picture Science for Feb 10, 2025: Chasing an Asteroid









Big Picture Science: Chasing an Asteroid

Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We’ll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.

Big Picture Science for Feb 03, 2025: Coming to Our Animal Senses









Big Picture Science - Coming to Our Animal Senses

REPEAT
Animals experience the world differently. There are insects that can see ultraviolet light, while some snakes can hunt in the dark thanks to their ability to sense infrared. Such differences are not restricted to vision: Elephants can hear subsonic sounds, birds navigate by magnetism, and your dog lives in a world marked by odors. In this episode, we speak to science journalist Ed Yong about how other creatures sense the world. Could we ever understand what it’s like to have the hearing of a bat or the sight of a hawk?
