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.
To avoid passing on new mutations to offspring, plants may minimize the number of divisions by the stem cells that make flowers and seeds.
The computer vision scientist Greg Johnson is building systems that can recognize organelles on sight and show the dynamics of living cells more clearly than microscopy can.
Theories about how animals became multicellular are shifting as researchers find greater complexity in our single-celled ancestors.
Researchers struggle to incorporate ongoing evolutionary discoveries into an animal classification scheme older than Darwin.
Contrary to popular belief, bacteria have organelles too. Scientists are now studying them for insights into how complex cells evolved.
