Sounding rockets represent an excellent platform for testing the influence of space conditions during the passage of Earth's atmosphere and re-entry on biological, physical and chemical experiments for astrobiological purposes.

Two Northeastern University researchers and their international colleagues have created an advanced model aimed at exploring the role of neutral evolution in the biogeographic distribution of ocean microbes.

Parts of the primordial soup in which life arose have been maintained in our cells today according to scientists at the University of East Anglia.

Scientists at The Scripps Research Institute have engineered a bacterium whose genetic material includes an added pair of DNA "letters," or bases, not found in nature. The cells of this unique bacterium can replicate the unnatural DNA bases more or less normally, for as long as the molecular building blocks are supplied.

If you have been watching the new series "Cosmos" recently then you have see Tardigrades or "water bears" featured. These creatures are remarkably resistant to a wide range of conditions that humans would consider extreme - if not deadly.

Capitalizing on the ability of an organism to evolve in response to punishment from a hostile environment, scientists have coaxed the model bacterium Escherichia coli to dramatically resist ionizing radiation and, in the process, reveal the genetic mechanisms that make the feat possible.

Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call 'living rotating crystals' that could serve as a nanopump. They may also, incidentally, shed light on the origin of life itself.

All living organisms on Earth could soon have a new name if a Virginia Tech professor has his way. Boris Vinatzer has developed a system that classifies and names organisms based on their genome sequence.

Modeling a Near-optimal Genetic Code

Researchers have created a model that may explain the complexities of the origins of life. Their work, which appears in the Journal of the Royal Society Interface, offers new insights into how RNA signaling likely developed into the modern "genetic code."
