New Study Outlines 'Water World' Theory of Life's Origin
Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple […]

Pinwheel 'Living' Crystals and the Origin of Life
Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call ‘living rotating crystals’ that could serve as a nanopump. They may also, incidentally, shed […]

Ancient Minerals on Earth and the Origin of Life
Astrobiologists supported by the NASA Astrobiology Institute have shown that mineral species on the early Earth may have been different than the ones found on our planet today. The researchers […]

Clay May Have Been The Birthplace of Life
Clay, a seemingly infertile blend of minerals, might have been the birthplace of life on Earth. Or at least of the complex biochemicals that make life possible, Cornell University biological […]

New Research Supports Theory That Life Started on Mars
Professor Steven Benner will tell geochemists gathering today (Thursday, 29 August) at the annual Goldschmidt conference that an oxidized mineral form of the element molybdenum, which may have been crucial […]

Evidence for Iron-Rich Ancient Ocean Changes View of Earth’s Early History
Over the last half-billion years, the ocean mostly has been full of oxygen and teeming with animal life. But earlier, before animals evolved, oxygen was harder to come by. Now […]

An Oxygen-poor ‘Boring’ Ocean Challenged Evolution of Early Life
A research team led by biogeochemists at the University of California, Riverside has filled in a billion-year gap in our understanding of conditions in the early ocean during a critical […]
