  • A new study used demographic data to explore current and projected population changes around the world. Europe and Asia are shrinking, while Africa is still growing.
  • For the first time in history, people aged 65+ outnumber children younger than five.
  • Underpopulation will cause serious challenges for sustainability.

  • Brain mapping is an attempt to identify the location of everything in the brain.
  • An accurate map of the brain would immeasurably enhance our ability to understand how it works.
  • The project is massive, involving multiple fields of biomedical research and expensive cutting-edge technology.

​Dyson spheres: The key to resurrection and immortality?

Creating an afterlife—or a simulation of one—would take vast amounts of energy. Some scientists think the best way to capture that energy is by building megastructures around stars.

  • In a 2018 paper, researchers Alexey Turchin and Maxim Chernyakov published a paper outlining various ways humans might someday be able to achieve immortality or resurrection.
  • One way involves creating a simulated afterlife, in which artificial intelligence would build simulations of past human lives.
  • Getting the necessary power for the simulation might require building a Dyson sphere, which is a theoretical megastructure that orbits a star and captures its energy.

  • Simulation theory proposes that our world is likely a simulation created by beings with super-powerful computers.
  • In "A Glitch in the Matrix," filmmaker Rodney Ascher explores the philosophy behind simulation theory, and interviews a handful of people who believe the world is a simulation.
  • "A Glitch in the Matrix" premiered at the 2021 Sundance Film Festival and is now available to stream online.
