The first issue of the new journal Cell Metabolism publishes the findings in its January 2005 edition.  more

Old dogs (and people) can learn new tricks; Diet, exercise, stimulating environment help
According to conventional wisdom, old dogs and new tricks aren't a good match. But a new study of beagles finds that regular physical activity, mental stimulation, and a diet rich in antioxidants can help keep aging canine--and perhaps human--brains in tip-top shape. The research, supported by the National Institute on Aging (NIA), a part of the National Institutes of Health (NIH), is among the first to examine the combined effects of these interventions and suggests that diet and mental exercise may work more effectively in combination than by themselves.  more

Fat hormone acts on brain circuit to curb obesity, diabetes
New research published in the premier issue of Cell Metabolism finds that a single brain region is sufficient for normal control of blood sugar and activity level by the fat hormone leptin. The same region also exerts significant, though more modest, control over leptin's effects on body weight. The findings in mice provide insight into potential mechanisms underlying type II diabetes and suggest new avenues for treatment, according to the researchers. more
