New experiments reveal how the brain chooses which memories to save and add credence to advice about the importance of rest.

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.

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.

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.

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.

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.

Recent observations of an aging, alien planetary system are helping to answer the question: What will happen to our planet when the sun dies? Read more at QuantaMagazine.org. Music is “Dark Toys” by SYBS.
