Science News: A computer may one day be able to decode the vivid imagery of dreams. Yukiyasu Kamitani of the Advanced Telecommunications Research Institute International in Japan and coworkers conducted a study in which they captured brain scans of three men while they slept. Then the researchers woke the men and asked detailed questions about their dreams. After gathering some 200 reports, the researchers grouped the dreamed objects, such as streets, furniture, and people, into categories. Then the study participants’ brains were scanned again while they looked at images of things in those categories. By using computer algorithms to link particular brain patterns with particular objects, the researchers were able to determine with about 70% accuracy which of two objects appeared in a dream.
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
Modeling the shapes of tree branches, neurons, and blood vessels is a thorny problem, but researchers have just discovered that much of the math has already been done.
