A New Doorway to the Brain
Neuroscientists can now explore the “wild west” in our heads in incredible detail—a boon to medicine and understanding what makes us tick.
How the Brain Allows the Deaf to Experience Music
Our sensory systems for hearing and touch overlap to stir a wealth of emotions.
Turing Patterns Turn Up in a Tiny Crystal
The mechanism behind leopard spots and zebra stripes also appears to explain the patterned growth of a bismuth crystal, extending Alan Turing’s 1952 idea to the atomic scale.
Neurons Unexpectedly Encode Information in the Timing of Their Firing
A temporal pattern of activity observed in human brains for the first time may explain how we can learn so quickly.
The Curious Strength of a Sea Sponge’s Glass Skeleton
A glass sponge found deep in the Pacific shows a remarkable ability to withstand compression and bending, on top of the sponge’s other unusual properties.
