Understanding how basic molecules called enantiomers form in their purest state could provide us with critically important new data about the origins of life on our planet, Spanish researchers say.A team there recently managed to conduct a new series of investigations on these molecules, which are basically one of tw... |

There are few ideas in the world that had groundbreaking implications on the way we understand science. The microscope, the telescope and some theories are examples of this, but now researchers are proposing a new approach to looking at life itself, and at how it developed. One of the major realizations that we had w... |

Investigators say that it's high time to begin a serious search for sings of present or past life on Mars. Landers and rovers we've sent there have shown us so much of how the planet works, but now it's time to start searching for the thing we set out to find in our space explorations – life some... |

For many years, scientists have been arguing that the earliest life forms developed here inside oceans or pools of water, in places where the organisms had millions of years to develop and thrive. A new theory has however been gaining momentum lately, which states that life originated high up in the Earth's atmo... |

A new twist in an established theory argues that all life on Earth may have developed from the remains of dead alien viruses, that arrived here on comets and other space impactors. This is a new form to the old idea of panspermia, which says that life did not originally develop here. Some experts now believe that vir... |

Most people only think of comets as enders of worlds, but some scientists are making a strong case that the space objects are more likely cosmic arks of life, taking life-precursor molecules through space in all directions. Some of these objects may have done this for our planet as well, say investigators. In additio... |

It's no lie, even if this is another kind of eruption – one in which life erupts from what was once a death-spreading mountain. Mount St. Helens is very well known for its huge eruption back in 1980, an event that didn't surprise anybody and that left visible traces until today. “It began with... |
