The Brain Processes Speech in Parallel With Other Sounds
19:26
Scientists thought that the brain’s hearing centers might just process speech along with other sounds. But new work suggests that speech gets some special treatment very early on.

A Massive Subterranean ‘Tree’ Is Moving Magma to Earth’s Surface
22:40
Deep in the mantle, a branching plume of intensely hot material appears to be the engine powering vast volcanic activity. The post A Massive Subterranean ‘Tree’ Is Moving Magma to Earth’s Surface first appeared on Quanta MagazineOne Lab’s Quest to Build Space-Time Out of Quantum Particles
21:30
For over two decades, physicists have pondered how the fabric of space-time may emerge from some kind of quantum entanglement. In Monika Schleier-Smith’s lab at Stanford University, the thought experiment is becoming real. The post One Lab’s Quest to Build Space-Time Out of Quantum Particles first appeared on Quanta MagazineThe New Thermodynamic Understanding of Clocks
18:13
Investigations of the simplest possible clocks have revealed their fundamental limitations — as well as insights into the nature of time itself. The post The New Thermodynamic Understanding of Clocks first appeared on Quanta MagazineThe Brain Doesn’t Think the Way You Think It Does

Familiar categories of mental functions such as perception, memory and attention reflect our experience of ourselves, but they are misleading about how the brain works. More revealing approaches are emerging. The post The Brain Doesn’t Think the Way You Think It Does first appeared on Quanta MagazineEternal Change for No Energy: A Time Crystal Finally Made Real
22:20
Like a perpetual motion machine, a time crystal forever cycles between states without consuming energy. Physicists claim to have built this new phase of matter inside a quantum computer.
