Working from a sliver of tissue no bigger than a grain of rice, researchers have built an astoundingly complex map of the human brain. The tiny fragment contains 57,000 cells, 230 millimeters of ...

Researchers have developed a novel brain sensor that picks up on users' brain signals with impressive accuracy—and it's so small that it can be weaved into the base of the hair. Only slightly ...

Those with the microbes from the small-brain species stored more of the energy as fat. New research suggests the gut microbiome could have influenced energy availability to evolve a larger brain.

Scientists announced on Thursday a milestone in neurobiological research with the mapping of the entire brain of an adult fruit fly, a feat that may provide insight into brains across the animal ...

Astronomers have discovered the smallest dwarf galaxy ever seen. It is a mystery how the satellite galaxy of Andromeda survived the blistering conditions of the early universe.

(CNN) — Ten years ago, Dr. Jeff Lichtman — a professor of molecular and cellular biology at Harvard University — received a small brain sample in his lab.
