Ice Ages that covered much of the world in glaciers are thought to have occurred twice during the Cryogenian period, between about 720 and 660 million years ago, and again from 650 to 640 million years ago. Credit: NSF
Researchers have discovered what they think are fossils of a unique red algae species that lived about 650 million years ago during a brief respite between some of the most extreme ice ages the world has ever known. The fossils could speak to how life coped in the aptly named Cryogenian period, when glaciers held most of Earth ...

Researchers studying living and fossil marine bivalves are providing new insights into how geographic range relates to the evolution of diversity in families of organisms. The study, supported in part by the Exobiology & Evolutionary Biology element of the NASA Astrobiology Program, focuses on how an organism’s position in a morphospace can affect evolution.
A 'morphospace’ is a way of representing an organism’s possible form, shape or structure. A morphospace has multiple dimensions, and each axis corresponds to a different character of the organism being studied. A single point on the morphospace represents an individual organism in the population.
The study ...June 22, 2015 / Written by: Aaron Gronstal

This view looks across the geyser basin of Saturn’s moon Enceladus, along fractures spewing water vapor and ice particles into space. Cassini scientists have pinpointed the source locations of about 100 geysers and gained new insights into what powers them. Image credit: NASA/JPL-Caltech/SSI
Researchers supported in part by the NASA Astrobiology Institute have revealed the pH of water in the geyser-like plumes of Enceladus. The findings could help astrobiologists understand the potential for past or present life on Saturn’s sixth-largest moon. Click here to view the press release from the Carnegie Institute.

The next mission to Mars could carry a smarter rover that is able to make better decisions absent instructions from Earth. Engineers are looking to automate some of the simple decision-making steps undertaken by rovers and orbiters, which could dramatically improve the science they are able to perform in the search for habitable environments.
This is the focus of the TextureCam Intelligent Camera Project, a NASA system that enhances autonomous investigations. TextureCam will allow ...

Microbes Can Survive In Meteorites If Shielded From UV Radiation
Understanding how well microbes can survive in space is of importance when sending out orbiters or landers around bodies that might present the right conditions for life, such as Mars. Scientists want to be careful to avoid contaminating other worlds with life from our own. And microbes’ resilience to Outer Space enhances the prospects of panspermia, in which life can be seeded between ...

Protocells are thought to be precursors to life’s first living cells and, in their simplest form, are a self-organized spheres of lipids. New research is providing insight into the environment in which protocells on the early Earth could have formed. The work indicates that protocells may have been crowded by small molecules and polymers. This crowding could have affected reaction rates, changed the structure and activity of water, and even enhanced the ...June 10, 2015 / Written by: Aaron Gronstal
A process known as intramolecular nucleosidation led to high yields of the molecule orotidine. This process could have implications for the prebiotic formation of nucleosides. Credit: Kim and Krishnamurthy (2015).
Astrobiologists supported in part by the Exobiology & Evolutionary Biology element of the NASA Astrobiology Program have provided new insight into a process that could have implications for the formation of nucleosides on the early Earth. A nucleoside is a component of genetic material in living cells, and is composed of a nucleobase attached to a sugar.
The study, “Synthesis of orotidine by intramolecular nucleosidation,” was published in the journal Chemical Communications.

Understanding the origin of bio-organic molecules is a key step in determining how life on Earth began. In 1953, the Miller-Urey experiment showed that amino acids can be produced by electrical discharges in simple gases. Ever since then, scientists have demonstrated that many organic compounds can be formed from non-biological processes.
Astrobiologists are now trying to determine how biomolecules used by life were selected from the complex mixture of molecules that may have been available on the early Earth. Of particular interest is the ...June 5, 2015 / Written by: Aaron Gronstal

Researchers studying ocean chemistry around the end-Triassic extinction (ETE) event have revealed new details about how oxygen availability in ocean water could have disrupted Earth’s nitrogen cycle and the ecological turnover in certain groups of organisms. Their results provide the first evidence for what is known as photic zone euxinia (PZE) associated with this event in Earth’s history.
