Collision-course science: when a single locust joins a swarm
If an animal is to cope with changing environmental conditions, activity in its nervous system must also change. Scientists from Cambridge and Oxford are studying these changes in collision-detecting nerve cells in the visual system of the locust, an insect that alternates between two lifestyles. Their research, to be presented at the SEB... view more... (2003-03-26)

Automated analysis of MR images may identify early Alzheimer's disease
Analyzing MRI studies of the brain with software developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) may allow diagnosis of Alzheimer's disease and of mild cognitive impairment, a lesser form of dementia that precedes the development of Alzheimer's by several years. view more (2009-05-22)
