Science in Action   /     The First Stars in the Universe

Description

Astronomers using the James Webb Space Telescope think they have seen the glow from the first generation of stars after the Big Bang. The Anthropocene is meant to mean the latest geological era in which humanity is shaping the rocks and environment of our planet. But an unexpected vote by a commission has declined the idea of making this an official definition. Roland hears from one of its leading proponents what happened and why it matters. And, new research indicates that bumblebees can show each other how to solve puzzles too complex for them to learn on their own. Professor Lars Chittka put these clever insects to the test and found that they could learn through social interaction. How exactly did the experiment work, and what does this mean for our understanding of social insects? Reporter Hannah Fisher visits the bee lab at Queen Mary University in London. Plus, the subterranean South American snake that feeds its hatchlings milk from specially evolved glands.
