Analysis of the crystals showed they contain a form of carbon often associated with plants and bacteria. The rare gems were found inside zircon crystals, formed a few hundred million years after the Earth came into being. picked by deEPCHIll 5 months ago tags diamond hint earliest life earth trace |

Now, a team of researchers working in New Mexico has found traces of life inside salty halite crystals. The discovery is "an invaluable resource for understanding the evolutionary record [of Earth] over a geological time frame." picked by AutumnLotus 4 months ago 0 comments edit related share science |
Researchers studying life in the deep subsurface of our planet have discovered a unique bacterium living 1 mile (1.7 km) below the Earth's surface. The tiny bacteria live in a community of subsurface microbes inhabiting a South African platinum mine. picked by AutumnLotus 4 months ago 0 comments edit related share science |
Organic compounds contain carbon and hydrogen and form the building blocks of all life on Earth. By analyzing organic material and minerals in the Martian meteorite Allan Hills 84001, scientists have shown for the first time that building blocks of life formed on Mars early in its history. Previously, scientists have thought that organic material in ALH 84001 was brought to Mars by meteorite impac... read full post picked by AutumnLotus 12 months ago 1 comments edit related share plime.com |
Beetles first appeared on Earth at the same time as the earliest dinosaurs but turned out to be much better survivors, a new evolutionary study has shown. Today, there are an estimated 350,000 known species of beetle on Earth, and probably several million more yet to be discovered, say scientists. The insects account for about a quarter of all life forms on the planet. picked by AutumnLotus 12 months ago 0 comments edit related share plime.com |

Diamonds more than 4 billion years old -- nearly as old as the Earth itself -- have been discovered in Western Australia, giving scientists vital clues about the early history of our planet. picked by AutumnLotus 1 year ago 1 comments edit related share plime.com |
Diamonds may be rare on Earth, but surprisingly common in space and the super-sensitive infrared eyes of NASA's Spitzer Space Telescope are perfect for scouting them. These gems are about 25,000 times smaller than a grain of sand, but astronomers believe that these tiny particles could provide valuable insights into how carbon-rich molecules, the basis of life on Earth, develop in the cosmos. picked by AutumnLotus 9 months ago 2 comments edit related share science |
Some crucial ingredients for life on Earth may have formed in interstellar space, rather than on the planet's surface. A new computer model indicates clouds of adenine molecules, a basic component of DNA, can form and survive the harsh conditions of space, and possibly sprinkle onto planets as the stars they orbit travel through a galaxy. picked by AutumnLotus 1 year ago 2 comments edit related share science |
Geologists have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today. The study suggests that upheavals in the earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world’s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere. picked by AutumnLotus 1 year ago 4 comments edit related share science |

Scientists using ESA’s Venus Express are trying to observe whether Earth is habitable. Silly, you might think, when we know that Earth is richly stocked with life. In fact, far from being a pointless exercise, Venus Express is paving the way for an exciting new era in astronomy. picked by AutumnLotus 2 months ago 1 comments edit related share science |

An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry "handedness" in a larger number than previously thought. They studied the organic materials of a special group of meteorites that contain among a variety of compou... read full post picked by AutumnLotus 9 months ago 1 comments edit related share science |

A hardy life form called cyanobacteria can grow in otherwise inhospitable lunar soil, new experiments suggest. Future colonists on the Moon might be able to use the cyanobacteria to extract resources from the soil that could be used to make rocket fuel and fertiliser for crops. picked by AutumnLotus 9 months ago 1 comments edit related share science |
Our planet is changing before our eyes, and as a result, many species are living on the edge. Yet Earth has been on the edge of habitability from the beginning. New work shows that if Earth had been slightly smaller and less massive, it would not have plate tectonics-the forces that move continents and build mountains. And without plate tectonics, life might never have gained a foothold on our wor... read full post picked by AutumnLotus 11 months ago 1 comments edit related share science |
Twinkling stars are often compared with diamonds, sparkling and bright. Stars are made almost entirely of hydrogen and helium with traces of other elements; diamonds are made of carbon. However, there are real diamonds in the sky, and they derive from the fiery furnaces that make stars shine. picked by AutumnLotus 1 year ago 1 comments edit related share plime.com |
