Influencers on Earth and in Space: Social Media, Origins of Life, and Orbital Data Centers
Episode 610 sheds light on how social media shapes user decisions, discusses space data centers, and explores the origins of life on Earth.
In this episode, Leonardo and Francesca discuss social networks and orbital data centers. Leonardo begins by explaining how platforms like X (Twitter) can influence voters' political choices through algorithmic or chronological feed selection.
Out in the field, we join Valeria as she interviews Edoardo Gianni, a researcher at the MRC Laboratory of Molecular Biology in Cambridge. Edoardo discusses self-replicating RNA as a potential origin of life on Earth. He explains what ribozymes are and highlights the unique properties of the QT45 ribozyme he discovered, with its activity detailed in a recent article in Science (https://doi.org/10.1126/science.adt2760).
We return to the studio for our usual "bad joke" and then hear from Francesca, who will talk about orbital data centers. She will analyze the challenges involved and explore the actual feasibility of these ambitious (and perhaps futuristic) projects.

New Mutations Help H5N1 Bird Flu Virus Infect Cows, Not People
Recent research highlights the ongoing evolution of the H5N1 bird flu virus within livestock populations. The study reveals specific genetic changes that have enabled the virus to successfully infect cattle. Crucially, these mutations do not appear to facilitate human infection, indicating a cu
Why Birds Outlasted the Dinosaurs: Understanding the End-Cretaceous Extinction
Scientists have finally unlocked the secrets behind the remarkable survival of birds, the only dinosaur lineage to emerge victorious from the devastating mass extinction event at the end of the Cretaceous period. While a catastrophic asteroid impact led to the demise of all other non-
Cosmic Rays: A Revolutionary Tool for Locating Critical Minerals Deep Underground
With readily accessible deposits of valuable ore diminishing, the mining sector is turning to an innovative solution: subatomic particles. These cosmic rays are being employed to create detailed maps of rock formations far below the surface, aiding in the discovery of essential minerals.
