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

1 SOCIAL MEDIA CAN BOOST YOUR MEMORY

A study from Cornell University found that people who posted about events online were more likely to remember those events over time, regardless of how significant they were.

2 MOST DEPRESSED PEOPLE AREN’T GETTING PROPER TREATMENT

Analysis of a survey of over 46,000 adults published in JAMA Internal Medicine found that less than a third of people who said they were depressed had been treated for their symptoms and that many others who were on antidepressants weren’t receiving the appropriate dosage.

3 MOST PROSTATE-CANCER TREATMENT DOESN’T SAVE LIVES

A landmark study found no difference in survival in men who chose active surveillance–monitoring with no treatment–as opposed to surgery and radiation, which can come with severe side effects. Even though their cancer appeared to progress, men who decided to forgo treatment were no more likely to die of the disease after 10 years.
