While we sleep, one kind of slow brain wave helps to reinforce memories, but a competing wave weakens them.
Researchers have discovered a surprising mathematical relationship in the brain’s representations of sensory information, with possible applications to AI research.
Studies suggest that epigenetics allows some learned adaptive responses to be passed down to new generations. The question is how.
The 2019 Nobel Prize in Physiology or Medicine honored William Kaelin Jr., Peter Ratcliffe and Gregg Semenza for their work on elucidating how cells adjust to low oxygen levels.
Cells in symbiotic partnership, sometimes nested one within the other and functioning like organelles, can borrow from their host’s genes to complete their own metabolic pathways.
Only 170 million years ago, new plankton evolved. Their demand for carbon and calcium permanently transformed the seas as homes for life.
A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.
Maintaining perfect stability through negative feedback is a basic element of electrical circuitry, but it’s been a mystery how cells could do it — until now.
