Ben-Gurion University of the Negev (BGU) researchers have discovered deep freshwater springs on the Dead Sea floor that feed into this rapidly dwindling body of water.
A University of Alberta-led research team has discovered that billions of years before life evolved in the oceans, thin layers of microbial matter in shallow water produced enough oxygen to support tiny, mobile life forms.
The scalding-hot sea that supposedly covered the early Earth may in fact never have existed, according to a new study by Stanford University researchers who analyzed isotope ratios in 3.4 billion-year-old ocean floor rocks.
A NASA-funded study suggests humans might not exist today if not for the ancient fusing of two microscopic, single-celled organisms called prokaryotes. Biologist James Lake of the UCLA Center for Astrobiology compared proteins present in more than 3,000 different prokaryotes -- a type of single-celled organism without a nucleus -- and discovered two major classes of relatively simple microbes fused together more than 2.5 billion years ago. That endosymbiosis, or merging of two cells, he said,...
Findings may provide insight into the origins of life on Earth, and even the search for life on Mars.
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments.
The wonderland known as Yellowstone National Park has yielded a new marvel - an unusual bacterium that converts light to energy.
LONDON (Reuters) - Rock formations in Western Australia may not only be some of the earliest evidence of life on Earth but also the first signs of biodiversity, scientists said on Wednesday.
