Tweets can better predict heart disease rates than income, smoking and diabetes, study finds
The Washington Post: Is Twitter becoming a new public health database? The latest evidence: A group of researchers has found that analyzing tweets can accurately predict the prevalence of heart disease.

The findings from the University of Pennsylvania were published this week in the journal Psychological Science.

How the Brain Stores Trivial Memories, Just in Case
The New York Times: The surge of emotion that makes memories of embarrassment, triumph and disappointment so vivid can also reach back in time, strengthening recall of seemingly mundane things that happened just beforehand and that, in retrospect, are relevant, a new study has found.

Positive thinking? It’s not enough to reach your goals
USA Today: "Dream it. Wish it. Do it" is a popular T-shirt slogan. It is not a very good way to change your life – as countless people who made New Year's resolutions to lose weight, start exercising or improve work habits are learning right about now. Positive thinking has its merits, but it has been seriously oversold as a way to achieve goals, a growing body of research shows.
