Are Volcanoes Responsible for Life?
An experiment carried out more than 50 years ago has revealed that volcanoes may have played a crucial role in the formation of the first organic building blocks of life on Earth.
More surprising than volcanoes' role in creating life is that the supporting research has been lost for fifty years. "Laboratory samples left over from a 1958 experiment in an American university have revealed, with the help of modern analytical techniques, that scientists had unwittingly discovered that gases given off by volcanoes can be used to make the vital sulphur-containing amino acids of proteins. The discovery is further vindication of the pioneering experiments of Stanley Miller, who as a young graduate student demonstrated that a 'primordial soup' of water and a few simple gases can produce the more complex organic molecules of life."

A completely unexpected discovery beneath the ice.
- Scientists find remains of a tardigrade and crustaceans in a deep, frozen Antarctic lake.
- The creatures' origin is unknown, and further study is ongoing.
- Biology speaks up about Antarctica's history.
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.
It's one factor that can help explain the religiosity gap.
- Sociologists have long observed a gap between the religiosity of men and women.
- A recent study used data from several national surveys to compare religiosity, risk-taking preferences and demographic information among more than 20,000 American adolescents.
- The results suggest that risk-taking preferences might partly explain the gender differences in religiosity.
