This Just In

A roundup of new and noteworthy insights from the week’s most talked-about studies:

1 ACUPUNCTURE MAY HELP BABIES WHO CRY A LOT

A study in the journal Acupuncture in Medicine analyzed 147 babies with colic who cried for more than three hours a day at least three days per week; it found that those who received acupuncture treatment over two weeks had a greater reduction in crying than those who did not.

2 CELL PHONES MIGHT BE HURTING YOUR WORKOUT

A study in Performance Enhancement & Health found that participants’ balance and stability fell 45% if they texted during a workout and 19% if they talked on their cell phones, compared with those not using a device.

3 SITTING TOO MUCH COULD MAKE YOUR CELLS AGE FASTER

A report in the American Journal of Epidemiology found that for elderly women who exercised less than 40 minutes per day, those who spent 10 or more hours sedentary had cells that aged eight years more on average than those who were less sedentary. Women who met exercise recommendations did not have the same association.
