Workshop on the Potential for Finding Life in a Europa PlumeArtist’s conception of water vapor plume erupting from the icy surface of Europa, a moon of Jupiter, based on data from the Hubble Space Telescope. Credit: NASA/ESA/K. Retherford/SWRI
SAVE THE DATE: Wednesday, February 18, 2015
The NASA Astrobiology Institute (NAI) and the Solar System Exploration Research Virtual Institute (SSERVI) will co-host the Workshop on the Potential for Finding Life in a Europa Plume at NASA Ames Research Center, Moffett Field, California.
Current Europa missions under study by NASA are focused on answering the question, “Is Europa habitable?”. However, the potential presence of water plumes on the satellite could present an opportunity to pursue the question “Is there life on Europa?” Answering this question is far more challenging because measurements currently possible may provide only ambiguous results from a mission that either orbits or flies by Europa at relatively high velocity. To that end, NASA’s Planetary Science Division is convening a workshop to consider strategies to investigate Europa’s putative plumes for evidence of life.
A second announcement with further details and abstract submission instructions will be forthcoming, by early January 2015. Although participation in person is encouraged, provision will be made for remote participation. The workshop will be followed on Feb. 19-20 by a meeting of the Outer Planets Assessment Group that will also be held at the Ames Research Center.
Opportunity for Early Career Scientists to Participate in a Field Trip to the Key Astrobiology Sites of Australia
The NASA Astrobiology Institute (NAI) is accepting applications from early career astrobiologists (graduate students, postdoctoral fellows or others within 5 years of their Ph.D.) to participate in an 11-day trip to astrobiology-relevant field sites in Western Australia. Included will be the extant stromatolites of Shark Bay, the 2.5 Ga banded iron formations and an associated iron ore mine of the Hamersley Basin, the putatively cyanobacterial stromatolites of the 2.7 Ga Fortescue Group, and the 3.35-3.49 Ga fossiliferous and other units of the Pilbara Craton with what is arguably the oldest convincing evidence of life on Earth.
The expedition, from July 15 to July 25, 2015, will be led by Professor Malcolm Walter of the University of New South Wales, the founding director of the Australian Centre for Astrobiology (ACA). The trip is designed for scientists interested in the earliest life on Earth and early Earth environments. Additional information is available at http://aca.unsw.edu.au/
The NAI will provide partial support of $5000 each, for up to three individuals, for fieldtrip expenses. Selected individuals will then be responsible for the remainder of the expenses: airfare, visa fees, ground transportation to/from airports, etc.
Applicants should provide:
—a short description of how participation in this trip will contribute to your research or training in astrobiology
—a letter of support from your advisor/principal investigator
Applications are due by January 19, 2015 to Dr. Melissa Kirven-Brooks, Staff Scientist at the NAI, firstname.lastname@example.org.

A Study in Nonfunctional RNAAn artist's rendering of a Ribonucleic Acid (RNA) molecule. Credit: Nicolle Rager Fuller, National Science Foundation
By comparing nonfunctional and functional RNA, scientists have uncovered new details about the potential chemical evolution of one of life’s essential molecules. The study could provide new insight into RNA’s role in the origins of life on Earth.
The study, “RNA as an Emergent Entity: An Understanding Gained Through Studying its Nonfunctional Alternatives,” was supported by the National Science Foundation (NSF) and the NASA Astrobiology Program under the NSF/NASA Center for Chemical Evolution.
M-Dwarf Planets With Oxygen in Their Atmospheres?This artist's concept illustrates a young, red dwarf star surrounded by three planets. Image Credit: NASA/JPL-CalTech
NAI astrobiologists from the Virtual Planetary Laboratory at the University of Washington, graduate student Rodrigo Luger and professor Rory Barnes, have shown that many terrestrial planets in the habitable zones of low mass (M dwarf) stars could have experienced extreme stellar heating for up to 1 billion years after planet formation. This could lead to oceanic evaporation and atmospheric oxygenation. The study has been accepted for publication in Astrobiology.
Astrobiology AcupunctureScientists have programmed a robotic arm to poke the sample with an acupuncture needle. Credit: GA Tech
Researchers have turned to acupuncture in order to study samples from rough and uneven surfaces, such as rocks and meteorites. Using the technique, scientists have developed a robotic system that can collect samples from these non-planar surfaces.
The system uses a 3-D camera mounted on a robotic arm to map the irregular surface of an object. Then an acupuncture needle pokes and probes a tiny spot selected by the scientists. A minuscule amount of material is collected at the tip of the needle and is carried by the robotic arm to a mass spectrometer.
The work was supported by the Center for Chemical Evolution, a joint program from the National Science Foundation (NSF) and NASA Astrobiology Program. Initial funding came from a NSF Major Research Instrumentation (MRI) Program: Instrument Development Program grant.

Scientists have confirmed the existence of a process that causes the electrolysis of water, and which has the potential to drive the production of life in 'Snowball Earth’ scenarios and on icy satellites such as Europa and Enceladus.
The process, known as the Workman-Reynolds Effect (WRE), occurs when a dilute aqueous solution of salt rapidly freezes, causing ions in the solution to assume a negative or positive charge at the interface between ice and water.
Lack of Oxygen Delayed the Rise of Animals on EarthChris Reinhard and Noah Planavsky conduct research for the study. Credit: Yale University
New research could explain why it took around a billion years for animal species to flourish on Earth after oxygen levels in the atmosphere began to increase.
Animal life on Earth boomed around 800 million years ago at the end of the Proterozoic period, but scientists have long believed that there was sufficient oxygen in the atmosphere for this increase in animal diversity to occur much earlier. However, new findings published in the journal Science show that oxygen levels were only 0.1% of those we see today. The researchers theorize that oxygen levels were too low to support diverse species, and this delayed the rise of animals.
The study was supported in part by the Exobiology & Evolutionary Biology element of NASA’s Astrobiology Program.
Titan Glowing at Dusk and DawnHigh in the atmosphere of Titan, large patches of two trace gases glow near the north pole, on the dusk side of the moon, and near the south pole, on the dawn side. Brighter colors indicate stronger signals from the two gases, HNC (left) and HC3N (right); red hues indicate less pronounced signals. Image Credit: NRAO/AUI/NSF
New maps of Saturn’s moon Titan reveal large patches of trace gases shining brightly near the north and south poles. These regions are curiously shifted off the poles, to the east or west, so that dawn is breaking over the southern region while dusk is falling over the northern one.
The pair of patches was spotted by a NASA-led international team of researchers investigating the chemical make-up of Titan’s atmosphere.
Titan’s atmosphere has long been of interest because it acts as a chemical factory, using energy from the sun and Saturn’s magnetic field to produce a wide range of organic, or carbon-based, molecules. Studying this complex chemistry may provide insights into the properties of Earth’s very early atmosphere, which may have shared many chemical characteristics with present-day Titan.
The work was supported in part by NASA’s Astrobiology Program through a grant to the Goddard Center for Astrobiology, a part of the NASA Astrobiology Institute.

Graduate Student Positions Exploring Major Evolutionary Transitions – NAI at the University of Montana (Admitting for Fall 2015)
Graduate Admissions Deadline: January 15, 2015
Evolution of complexity via multicellularity and cell differentiation in the green alga Chlamydomonas
PI Matt Herron; email@example.com
How and why organismal complexity increases are central questions in evolutionary biology. Although the vast majority of life forms remain simple, both the maximum and the average levels of complexity have increased from the origin of life to the present day. Large increases in organismal complexity resulted from a series of events in which existing individuals combined to become parts of a new kind of individual with components specialized for various roles. Such events are known as major transitions and include the emergence of cellular life from groups of interacting molecular replicators, of eukaryotes from two prokaryotes, of multicellular organisms from unicells, and of eusocial “superorganisms” from individual animals. Among such transitions, the evolution of multicellular organisms from single-celled ancestors set the stage for unprecedented increases in complexity, especially in land plants and animals. We have used the unicellular green alga Chlamydomonas reinhardtii to experimentally generate de novo origins of simple (undifferentiated) multicellularity in two separate experiments. Using these newly-evolved, multicellular Chlamydomonas, we plan to ascertain the genetic bases underlying the evolution of multicellularity, evaluate the role of genetic assimilation in the evolution of multicellularity, and observe the evolution of multicellular development in real time.
An experimental model for eukaryogenesis: Co-evolution of Escherichia coli and its parasite Bdellovibrio bacteriovorus
PI Margie Kinnersley; Margie.Kinnersley@mso.umt.edu
Among the major evolutionary transitions, perhaps the most crucial to understanding extant biodiversity is the transition from prokaryote to eukaryote (eukaryogenesis). Because the timing of eukaryogenesis coincides with the phylogenetic origin of the mitochondrion, it has been hypothesized that acquisition of this organelle heralded the prokaryote-eukaryote transition and preceded the rapid diversification referred to as the eukaryotic big bang. By selecting for metabolic interdependence between the intracellular prokaryotic predator Bdellovibrio bacteriovorus and its host, an acetate-excreting strain of Escherichia coli, we plan to establish a simple, straightforward model for mitochodrial acquisition based on the “parasitism hypothesis” of mitochondriogenesis. This co-evolving system will be used to test hypotheses concerning ecological prerequisites for, early molecular events in, and evolutionary consequences of incipient endosymbiosis based on metabolic niche partitioning and energy generation, exactly the features that define the mitochondrion’s role in eukaryotic systems. Understanding these aspects of symbiogenesis is essential for truly understanding the prokaryotic/eukaryotic transition and thus is applicable to the study of myriad aspects of cellular and organismal diversity.
