Pink Noise While Asleep Helps Memory R
esearchers from Northwestern University have found that acoustic stimulation using pink noise (random sound with more low fre- quencies than white noise) increases slow-wave brain activity, thus improving sleep-dependent memory retention. Thirteen mature adults completed two nights of sleep; one with the pink noise and one without, in random order. Specific brainwave activity increased during the periods when the pink noise was being delivered, suggesting that it could help older adults preserve some memory functions.
esearchers from the Dana Farber Cancer Institute examined nutrition and cancer recur- rence data from 826 patients with Stage III colon cancer and found those that consumed two or more ounces of tree nuts a week experienced a 42 percent reduction in cancer recurrence and a 57 percent lower risk of death on average compared to those that ate no nuts.

TAI CHI EASES THE BLUES Boston researchers found a reduction in depressive symptoms among people that practice tai chi via 50 Chinese-Americans diagnosed with depression. They were divided into three groups. One group participated in tai chi sessions twice a week and were encouraged to practice the movements at home three times a week. Another group attended twice weekly depression education sessions and a third served as the control group. After 12 weeks, the tai chi group reported significant improvements in depression symptoms, which continued after the study was completed, measured at 24 weeks.
