A British-led study has confirmed for the first time that an important component of early genetic material is extraterrestrial in origin. The scientists from Imperial College London say an important component of early genetic material found in meteorite fragments suggests parts of the raw materials to make the first molecules of DNA and RNA might have come from the stars. The scientists, from Europe and the United States, said the materials they found include the molecules uracil and...

Scientists have confirmed for the first time that an important component of early genetic material which has been found in meteorite fragments is extraterrestrial in origin. The finding suggests that parts of the raw materials to make the first molecules of DNA and RNA may have come from the stars. The scientists, from Europe and the USA, say that their research, published in the journal Earth and Planetary Science Letters, provides evidence that life's raw materials came from sources beyond...

Flash back three or four billion years "” Earth is a hot, dry and lifeless place. All is still. Without warning, a meteor slams into the desert plains at over ten thousand miles per hour. With it, this violent collision may have planted the chemical seeds of life on Earth.Scientists presented evidence today that desert heat, a little water, and meteorite impacts may have been enough to cook up one of the first prerequisites for life: The dominance of "left-handed" amino acids, the...

Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today.Scientists believe their research, published online in the journal Meteoritics and Planetary Science, provides fresh insights into the origins of life on Earth.Amino acids form the basis of proteins and enzymes, which are the building blocks of all biological life. They have been found in ancient...

An important discovery has been made with respect to the mystery of "handedness" in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, 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. The work is being published in this week's Early Edition of the Proceedings of the National Academy of Sciences (PNAS). The paper is titled,...

Carl Sagan famously said, "We are made of star-stuff." In the last few years, discoveries have revealed how this star-stuff could have played a role in life's origin. While such findings provide hope that life is widespread in the universe, it also creates a challenge for astrobiologists searching for life on other worlds. NASA -- Life on Earth was made possible by the death of stars. Atoms like carbon and oxygen were expelled in the last few dying gasps of stars after their final supplies of...
