Latest Abiogenesis Stories
The idea of discovering a new form of life has not only excited astronomers and astrobiologists for decades, but also the wider public.
Researchers have created artificial genetic material known as Xenonucleic acids, or XNAs, that can store information and evolve over generations in a comparable way to DNA.
Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system.
According to a new analysis, even before the ribosome's many working parts were recruited for protein synthesis, proteins also were on the scene and interacting with RNA.
In the beginning – of the ribosome, the cell's protein-building workbench – there were ribonucleic acids, the molecules we call RNA that today perform a host of vital functions in cells.
Investigating the history of water on Earth is critical to understanding the planet's climate. One central question is whether Earth has always had the same amount of water on and surrounding it, the same so-called "water budget".
Sugars give rise to enormous biochemical interest given the importance and diversity of the functions they carry out: they act as an energy storage system and serve as fuel for a number of biological systems; they form part of DNA and of ribonucleic acid (RNA) and, moreover, play a key role in cell processes.
Volcanic-hydrothermal flow channels offer a chemically unique environment, which at first glance appears hostile to life.
An international team of scientists led by University of Hawai'i at Mānoa Professor Ralf I. Kaiser, Alexander M. Mebel of Florida International University, and Alexander Tielens of Leiden Observatory in the Netherlands, discovered a novel chemical route to form polycyclic aromatic hydrocarbons (PAHs) – complex organic molecules such as naphthalene carrying fused benzene rings – in ultra-cold regions of interstellar space.
In the chemistry of the living world, a pair of nucleic acids—DNA and RNA—reign supreme.
