A roundup of new and noteworthy insights from the week’s most talked-about studies
1 AMERICANS ARE HAVING LESS SEX
A study in Archives of Sexual Behavior reports that the average American adult had sex 54 times per year from 2010 to 2014, nearly nine fewer times annually than from 2000 to 2004.
2 SOY MAY HELP PROTECT AGAINST CERTAIN BREAST CANCERS, AFTER ALL
A study in Cancer of more than 6,200 women with breast cancer found that those who ate more soy–a half to one serving per week–were 21% less likely to die over the next nine years. This contradicts previous research that suggested that soy increased the risk of death for women with certain types of breast cancer.

A Brain study of 80 people with carpal tunnel syndrome found that those who received acupuncture on the affected arm over eight weeks had less pain, improved wrist nerve conduction and partly repaired brain mapping in the short term, as well as better long-term functionality.
