Money Doesn't Buy Happiness
Raising a country from poverty to affluence should make the nation's population happier, right? Wrong, according to a new study of 54 countries worldwide.
Money doesn't buy happiness over the long term, a new study has found. The results apply to developed and developing countries worldwide, said study researcher Richard Easterlin, a professor of economics at the University of Southern California. "Happiness doesn't increase with the rate of economic growth even in less-developed countries or transitional countries," Easterlin told LiveScience. "We already know that to be true of developed countries, but now it's been extended to countries of lower levels of income." Easterlin and his colleagues reported the results this week (Dec. 13) in the journal Proceedings of the National Academy of Sciences.

A NASA astronomer explains how astronauts dispose of their, uh, dark matter.
- When nature calls in micro-gravity, astronauts must answer. Space agencies have developed suction-based toilets – with a camera built in to ensure all the waste is contained before "flushing".
- Yes, there have been floaters in space. The early days of space exploration were a learning curve!
- Amazingly, you don't need gravity to digest food. Peristalsis, the process by which your throat and intestines squeeze themselves, actually moves food and water through your digestive system without gravity at all.
She met mere mortals with and without the Vatican's approval.
- For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
- These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
- Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
A growing body of research shows promising signs that the keto diet might be able to improve mental health.
- The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
- Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
- Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.
