  • AI Starts to Sift Through String Theory's Near-Endless Possibilities

    16/10/2024 Duración: 25min

    Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles — though not yet those of our universe.

  • Insects and Other Animals Have Consciousness, Experts Declare

    02/10/2024 Duración: 18min

    A group of prominent biologists and philosophers announced a new consensus: There’s “a realistic possibility” that insects, octopuses, crustaceans, fish and other overlooked animals experience consciousness.

  • Dark Energy May Be Weakening, Major Astrophysics Study Finds

    18/09/2024 Duración: 20min

    A generation of physicists has referred to the dark energy that permeates the universe as “the cosmological constant.” Now the largest map of the cosmos to date hints that this mysterious energy has been changing over billions of years.

  • Brain's 'Background Noise' May Explain Value of Shock Therapy

    04/09/2024 Duración: 12min

    Electroconvulsive therapy is highly effective in treating major depressive disorder, but no one knows why it works. New research suggests it may restore balance between excitation and inhibition in the brain.

  • Swirling Forces, Crushing Pressures Measured in the Proton

    21/08/2024 Duración: 17min

    Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces and pressures inside a subatomic particle for the first time.

  • Never-Repeating Tiles Can Safeguard Quantum Information

    07/08/2024 Duración: 17min

    Two researchers have proved that Penrose tilings, famous patterns that never repeat, are mathematically equivalent to a kind of quantum error correction. Read more at QuantaMagazine.org. Music is “Quasi Motion” by Kevin MacLeod.

  • Radio Maps May Reveal the Universe's Biggest Magnetic Fields

    25/07/2024 Duración: 11min

    A controversial technique has produced detailed maps of the magnetic fields in colossal galaxy clusters. If confirmed, the approach could be used to reveal where cosmic magnetic fields come from.

  • New Clues for What Will Happen When the Sun Eats the Earth

    10/07/2024 Duración: 13min
