    Researchers report that some stickleback fish fathers can have long-term effects on the behavior of their offspring: The most attentive fish dads cause their offspring to behave in a way that makes them less susceptible to predators. These behavioral changes are accompanied by changes in gene expression, the researchers report.

    Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity – not just the degree to which he or she engaged in moderate or vigorous exercise, but also whether the person was sedentary the rest of the time.
