  • Brain Chemical Helps Signal to Neurons When to Start a Movement

    06/07/2022 Duración: 17min

    Dopamine, a neurochemical often associated with reward behavior, also seems to help organize precisely when the brain initiates movements. It’s the latest revelation about the power of neuromodulators. Read more at quantamagazine.org. Music is “Pulse” by Geographer.

  • This Animal's Behavior Is Mechanically Programmed

    22/06/2022 Duración: 25min

    Biomechanical interactions, rather than neurons, control the movements of one of the simplest animals. The discovery offers a glimpse into how animal behavior worked before neurons evolved. The post This Animal’s Behavior Is Mechanically Programmed first appeared in Quanta Magazine. Music is “Running Out” by Patrick Patrikios.

  • Tiny Galaxies Reveal Secrets of Supermassive Black Holes

    08/06/2022 Duración: 16min

    Dwarf galaxies weren’t supposed to have big black holes. Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed. Read more at QuantaMagazine.org. Music is “Light Gazing” by Andrew Langdon.

  • A Deepening Crisis Forces Physicists to Rethink Structure of Nature's Laws

    25/05/2022 Duración: 40min

    Physicists are reexamining a longstanding assumption: that big stuff consists of smaller stuff. The post A Deepening Crisis Forces Physicists to Rethink Structure of Nature’s Laws first appeared on Quanta Magazine

  • New Map of Meaning in the Brain Changes Ideas About Memory

    11/05/2022 Duración: 19min

    Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory.

  • A Solution to the Faint-Sun Paradox Reveals a Narrow Window for Life

    31/03/2022 Duración: 25min

    Back when the sun was 30% dimmer, Earth should have frozen solid. Yet water flowed and life blossomed. The solution to the paradox shows that we might have that faint sun to owe for life’s existence — with critical consequences for the possibility of life outside Earth. The post A Solution to the Faint-Sun Paradox Reveals a Narrow Window for Life first appeared on Quanta Magazine

  • Evolution ‘Landscapes’ Predict What’s Next for COVID Virus

    18/03/2022 Duración: 25min

  • Mathematicians Outwit Hidden Number Conspiracy

    17/02/2022 Duración: 21min

    Decades ago, a mathematician posed a warmup problem for some of the most difficult questions about prime numbers. It turned out to be just as difficult to solve, until now. The post Mathematicians Outwit Hidden Number Conspiracy first appeared on Quanta Magazine

  • Mathematician Hurls Structure and Disorder Into Century-Old Problem

    03/02/2022 Duración: 17min
