In this episode, we explore two fascinating discoveries in science from October 2024. First, we dive into the mysterious world of the Tsavo “man-eater” lions, infamous for terrorizing a Kenyan encampment in 1898. A new genomic study has analyzed the hairs compacted in their broken teeth, revealing insights into the lions’ diet, including giraffes, zebras, and humans. We’ll discuss the implications of these findings and how they offer a unique window into the ecosystems of the past.

Next, we turn our attention to groundbreaking research from Nature Neuroscience that challenges conventional wisdom about brain size and complexity. Scientists discovered that a highly accurate internal compass in fruit flies—creatures with tiny brains—can be generated by a neural network of just four neurons, as long as the connections are precisely adjusted. This revelation changes our understanding of what small brains can accomplish and opens up new possibilities in neuroscience.

Join us as we unravel these scientific breakthroughs and explore how they expand our knowledge of both the animal kingdom and neural computation!
