Facebook's mission "to make the world more open and connected" is a familiar refrain among company leaders. But the latest research shows connecting 1.1 billion users around the world may come at a psychological cost.
A new University of Michigan study on college-aged adults finds that the more they used Facebook, the worse they felt. The study, published in the journal PLOS One, found Facebook use led to declines in moment-to-moment happiness and overall life satisfaction.

We humans are a tribal lot. We can take the subtlest difference and drive it into a wedge seemingly worthy of anger, intolerance and violence. While there are situations where differences appear between people (or whole cultures) that demand lines be drawn, for the most part the fractures we create live in our heads.
Chia-Jung Tsay was something of a piano prodigy. By age 12, she was performing Mendelssohn in concert. At 16, she made her debut at Carnegie Hall. Soon, she was on her way to some of the best music schools in the country — Juilliard and the Peabody Conservatory. And she was throwing her hat in the ring for different competitions.

As a university professor, I've had the opportunity to view lectures from multiple vantage points. From the front of the room you see a sea of students — some attentive, a handful asleep and a good share semi-obstructed by the crisp plane of an open laptop.
The view is quite different From the back of the room. The eager-looking student near the door, keenly typing away, is on Facebook. The dozing student near the back might just have an earbud subtly snaking its way to his smartphone. Another student flits back and forth between a PDF of the lecture slides and her email.
The Voyager 1 spacecraft launched in 1977 on a mission to Jupiter and Saturn. It kept on going. Today it's billions of miles from Earth, and scientists have been predicting it will soon leave the solar system.

Online risk calculators are all the rage these days among public health groups trying to get us to change our unhealthful ways. The World Health Organization developed an online tool that lets you estimate your personal risk of cracking a hip in the next 10 years, for example.
