Latest Abiogenesis Stories
Tons, perhaps tens of tons, of carbon molecules in dust particles and meteorites fall on Earth daily. Meteorites are especially valuable to astronomers because they provide relatively big chunks of carbon molecules that are easily analyzed in the laboratory.
By Simon Hadlington Scientists are cooking up primeval ooze in the laboratory to try to discover how life on Earth first developed. Simon Hadlington lifts the lid on their brew A time traveller steps out of his machine on to the early Earth, around three billion years ago.
Study provides insight into how Earth's earliest cells may have interacted with their environment
Working with colleagues from NASA, a Florida State University researcher has published a paper that calls into question three decades of conventional wisdom regarding some of the physical processes that helped shape the Earth as we know it today.
Researchers from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn have detected for the first time a molecule closely related to an amino acid: amino acetonitrile. The organic molecule was found with a 30 meter radio telescope in Spain and two radio interferometers in France and Australia in the "Large Molecule Heimat", a giant gas cloud near the galactic centre in the constellation Sagittarius (Astronomy & Astrophysics, in press).
Could microbial life exist inside Enceladus, where no sunlight reaches, photosynthesis is impossible and no oxygen is available? The answer appears to be, yes, it could be possible. It is this tantalizing potential that brings us back to Enceladus for further study.
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.
An important discovery has been made with respect to the mystery of â€œhandednessâ€ in biomolecules.
Hydrocarbons â€“ molecules critical to life â€“ are being generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the mid-Atlantic Ocean.
Sulfur dioxide (SO2) may have played a key role in the climate and geochemistry of early Mars, geoscientists suggest. Their hypothesis may resolve longstanding questions about evidence that the climate of the Red Planet was once much warmer than it is today.
