The reasons why sleep is so vital often hide in unexpected parts of the body, as host Steven Strogatz discovers in conversations with researchers Dragana Rogulja and Alex Keene.
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.
The noted mathematician and author Steven Strogatz explains how the conversations with experts in his new Quanta Magazine podcast address his lifelong fascination with timeless mysteries.
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 discovery that short peptides can form spontaneously on cosmic dust hints at more of a role for them in the earliest stages of life’s origin, on Earth or elsewhere.
While watching a fearful memory take shape in the brain of a living fish, neuroscientists see an unexpected level of rewiring occur in the synaptic connections.
A 3D digital model of a “minimal cell” leads scientists closer to understanding the barest requirements for life.
Molecular detective work is zeroing in on the origins of sexual reproduction. The protein tools for cell mergers seem to have long predated sex — so what were they doing?
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.
