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.
Beneath our awareness, the brain lets certain kinds of stimuli automatically capture our attention by lowering the priority of the rest.
A brain circuit that suppresses distracting sensory information holds important clues about attention and other cognitive processes.
Origin-of-life researchers have usually studied the potential of pure starting materials, but messy mixtures of chemicals may kick-start life more effectively.
Modern humans and more ancient hominins interbred many times throughout Eurasia and Africa, and the genetic flow went both ways.
Modeling suggests that many embryonic cells commit to a developmental fate when they become too small to divide unevenly anymore.
Researchers found that elongating certain brain signals in rats improved their memory. The work revealed a new property to look out for in the hunt for “biomarkers” of learning.
Theories about how animals became multicellular are shifting as researchers find greater complexity in our single-celled ancestors.
By studying a swarm of flying midges as though it were a fluid, physicists have learned how collective behaviors might stabilize a group against environmental disruptions.
