1/30 NAI Director’s Seminar: Paul Davies, “Cancer as Metazoa 1.0”

Join us for the next NAI Director’s Seminar!

Date/Time: Monday, January 30, 2011 11:00AM Pacific

Presenter: Paul Davies (Arizona State University)

Abstract:
Cancer is widespread among eukaryotes, and can be successfully tackled only by understanding its place in the story of life itself – especially the evolution of multi-cellularity. In this seminar I will propose a new theory of cancer, drawing on insights from astrobiology. The central hypothesis is that cancer is an organized pre-programmed process driven by a cassette of highly conserved, deeply-evolved ancient genes – genes that are active in early-stage embryo development, and which become inappropriately re-awakened in the adult form. In effect, cancer tumors are atavisms, recapitulating an ancient life form – “Metazoa 1.0” – dating back to the dawn of multi-cellularity. This hypothesis differs fundamentally from the popular notion that cancers are deregulated rogue cells running amok, and explains cancer’s well-known robustness and resilience. It also offers a well-defined target for therapy.

In Memoriam: Lynn Margulis, 1938-2011

Lynn MargulisEvolutionary biologist Lynn Margulis, a long-time member of the astrobiology community, died at her home on November 22. She was 73.

Margulis was brilliant, passionate, dedicated, and insatiably curious, about science, education, and life. A superb communicator as well as an outstanding scientist, she participated in hands-on teaching activities at levels from middle to graduate school, served as a faculty mentor at Boston University for years, gave much of her time to public speaking, and authored numerous books about science for scientific and public audiences, many with her son Dorion. She has been, and will remain, an inspiration to many women and men who have had the privilege of knowing her. She is irreplaceable, and the astrobiology community will miss her very much.

Always a pioneer, Margulis was the first female principal investigator of NASA’s Exobiology Program (predecessor of Astrobiology), initially receiving funding for her research in microbial evolution and organelle heredity in the early 1970s. In 1980, Margulis established a Planetary Biology Internship (PBI) program, which the Exobiology/Astrobiology program has supported since its inception. Through the PBI program, which enables graduate students to work in the laboratories of scientists at NASA facilities and of NASA-supported scientists at universities, Margulis herself mentored many students who are now productive members of the astrobiology community. In 2010, Margulis served as a keynote speaker at a NASA symposium to mark the 50th anniversary of NASA’s Exobiology/astrobiology program. (A video record of this talk is available at: www.livestream.com/astrobiology50th.)

Born and raised in Chicago, Margulis entered the University of Chicago at age 14, receiving her A.B. there in 1957. She earned her M.S. from the University of Wisconsin in 1960 and her Ph.D. from the University of California, Berkeley, in 1963. For many years until her death, she served as Distinguished University Professor with the Department of Geosciences at the University of Massachusetts, Amherst. She was elected to the National Academy of Sciences in 1983 and was awarded the National Medal of Science in 1999. In 2008, she was one of thirteen recipients of the prestigious Darwin-Wallace Medal, traditionally bestowed every 50 years by the Linnean Society of London. She was also inducted into the World Academy of Art and Science, the Russian Academy of Natural Sciences, and the American Academy of Arts and Sciences. Her papers are permanently archived in the Library of Congress in Washington, DC.

Margulis is best known for her work on the theory of symbiogenesis, which describes how microbes evolve by means of long-lasting interactions between organisms, and her collaboration with friend and colleague James Lovelock (also an early Exobiology PI) on the Gaia hypothesis. Her work has contributed to establishing the bacterial origins of both chloroplasts and mitochondria, and her latest research focused on the possible origin of cilia from spirochetes. Among her most recent books are Symbiotic Planet: A new look at evolution (1998) and Acquiring Genomes: A theory of the origins of species (2002), co-written with Dorion Sagan. Her work with K. V. Schwartz provides a consistent formal classification of all life on Earth and has lead to the third edition of Five Kingdoms: An illustrated guide to the phyla of life on Earth (1998). Their evolutionary classification scheme was generated from scientific results of numerous colleagues.

Friends may contribute to the Lynn Margulis Memorial Fund to support students to continue her scientific research. Checks may be sent directly to “Lynn Margulis Memorial Fund” at Northampton Cooperative Bank, PO Box 550, Amherst, MA 01004.

Her family reports that plans are in the works to host a larger public celebration of Lynn’s life and science in the new year.





2011 NAI Director's Discretionary Fund Selections

The NASA Astrobiology Institute is pleased to announce selections for research awards resulting from its 2011 Director’s Discretionary Fund competition. The selections cover a wide range of research topics, from an examination of microbial succession on islands of floating pumice to defining the habitable zone’s outer edge by combining climate evolution models with models of orbital and obliquity evolution.

Discretionary resources in the fiscal year 2012 NAI budget are extraordinarily limited. Since these are the funds from which we make 2011 DDF awards, we have been limited to a small fraction of the total award amounts of past years. Approximately $250K is allocated for the seven selected investigations described in the link below.

Selections were based on external reviews, with selection priority given to proposals that


  • integrate the research of and realize synergies among the current NAI teams;

  • expand the scope of NAI research (and the NAI community) in innovative ways, accepting some risk in return for high pay-off potential;

  • respond in a timely way to new scientific results or programmatic opportunities;

  • develop connections between astrobiology research and other NASA science programs, particularly NASA’s Earth Science Program;

  • directly support flight programs, particularly through instrument development;

Recently Published Research from the NAI



Oxygen's Stops and Starts

Based on studies of rock cores, a team of geoscientists that include members of NAI's Penn State Team have determined that oxygen did not appear in Earth’s atmosphere in a single event. Instead, atmospheric oxygen came about in a long series of starts and stops.

The research was conducted using samples collected in the summer of 2007 during the Fennoscandia Arctic Russia – Drilling Early Earth Project (FAR DEEP). Scientists drilled a series of shallow, two-inch diameter cores and overlapped them to create a record of the Proterozoic Eon—2,500 million to 542 million years ago.

“We’ve always thought that oxygen came into the atmosphere really quickly during an event,” said Lee Kump, a geoscientist at Penn State University. “We are no longer looking for an event. Now we’re looking for when and why oxygen became a stable part of the Earth’s atmosphere.”

The research was published in the December 1, 2011 issue of Science Express under lead author Lee Kump.





Early Life More Complex than Previously Thought

MIT researchers have found hundreds of tiny fossils of the first known ciliates. The ciliates, named tintinnids, resided in hard, flask-shaped shells with bubbled exteriors that likely helped them float.

Anyone who has taken high school biology has likely come into contact with a ciliate. The much-studied paramecium is one of 7,000 species of ciliates, a vast group of microorganisms that share a common morphology: single-celled blobs covered in tiny hairs, or cilia. These cilia — Greek for “eyelash” — are used to propel a microbe through water and catch prey.

Today these hairy microbes are ubiquitous in marine environments. However, it’s unclear how long ciliates have inhabited Earth: After they die, members of most species simply disintegrate in their watery environs, leaving behind no fossilized remains.

Now, geologists at NAI's MIT Team and Harvard University have unearthed rare, flask-shaped microfossils dating back 635 to 715 million years, representing the oldest known ciliates in the fossil record. The remains are more than 100 million years older than any previously identified ciliate fossils, and the researchers say the discovery suggests early life on Earth may have been more complex than previously thought. What’s more, they say such prehistoric microbes may have helped trigger multicellular life, and the evolution of the first animals.

“These massive changes in biology and chemistry during this time led to the evolution of animals,” says Tanja Bosak, the Cecil and Ida Green Career Development Assistant Professor in MIT’s Department of Earth, Atmospheric and Planetary Sciences. “We don’t know how fast these changes occurred, and now we are finding evidence of an increase in complexity.”

Bosak and her colleagues have published the study in the October 21, 2011 issue of the journal Geology.

Earth's Early Atmosphere: An Update

Scientists from NAI’s New York Center for Astrobiology at Rensselaer Polytechnic Institute have used the oldest minerals on Earth to reconstruct the atmospheric conditions present on Earth very soon after its birth. The findings, which appear in the December 1, 2011 issue of Nature, are the first direct evidence of what the ancient atmosphere of the planet was like soon after its formation and directly challenge years of research on the type of atmosphere out of which life arose on the planet.

The scientists show that the atmosphere of Earth just 500 million years after its creation was not a methane-filled wasteland as previously proposed, but instead was much closer to the conditions of our current atmosphere. The findings, in a paper titled “The oxidation state of Hadean magmas and implications for early Earth’s atmosphere,” have implications for our understanding of how and when life began on this planet and could begin elsewhere in the universe.

Fossil Record, Meet Molecular Clock

A team of researchers including members of NAI's MIT team have married fossil records with molecular clock studies to reveal a new interpretation of the Cambrian explosion. Collectively these data allow an understanding of the environmental potential, genetic and developmental possibility, and ecological opportunity that existed before and during the Cambrian. The study compares the times of origin of major animal groups (from the molecular clock) with the times of their first appearance in the fossil record. The team shows that the major animal groups first diverged during the Cryogenian, roughly 300 million years prior to their appearance in the fossil record, and acquired the key components of their developmental toolkits early in their history. After a long lag, the groups’ major ecological successes are reflected in the records of the Ediacaran and Cambrian. Their paper appears in the current issue of Science.

Postdoctoral Positions for the Deep Life Initiative of the Deep Carbon Observatory

The Deep Life Directorate of the Deep Carbon Observatory (sponsored by the Alfred P. Sloan Foundation) will investigate the microbiology of the rock-hosted subsurface biosphere. Microbial communities contained within rock-hosted subsurface environments may be important conduits for the exchange of carbon and energy between the deep Earth and the biosphere- yet surprisingly little is known of their extent, their identities, or their activities. The research specifically addresses microbial carbon transformations in environments influenced by high hydrogen fluxes and abiogenic production of organic molecules. The research team consists of 17 scientists from 7 countries and contains both field and laboratory components. The Directorate seeks candidates for multiple Postdoctoral positions to work within this cooperative framework.

High Pressure Microbiology: Recently, unique environments deep beneath the continents and oceans have been sampled and we invite applications for a postdoctoral position to develop experimental approaches that will provide novel piezophilic cultivars whose activities can be investigated under in situ pressure-temperature conditions. This is a joint project between Isabelle Daniel’s Lab at the Université Claude Bernard Lyon 1 (France) and Doug Bartlett’s lab at the Scripps Institution of Oceanography, San Diego, CA (USA). Candidates should be highly motivated by research on the subsurface biosphere and have experience with experimental microbiology and/or spectroscopy under high pressure conditions.

Molecular Geomicrobiology: We invite applications for a postdoctoral position that will link stable isotope based approaches with metagenomic and transcriptomic studies of microbial metabolism of specific carbon compounds. The postdoc will be based in Matt Schrenk’s lab at East Carolina University (North Carolina, USA) with collaborators at the Marine Biological Laboratory (J. Huber). The postdoc will participate in analysis of samples from the high pH Coast Range Ophiolite serpentinite ecosystem and the Mid Cayman Rise deep-sea hydrothermal system. Applicants should have experience with microbial cultivation, molecular biology, and stable isotope analysis.

Hydrothermal Vent Microbiology: We invite applications for a postdoctoral position in hydrothermal vent microbiology in Julie Huber’s lab at the Marine Biological Laboratory (Woods Hole, MA). The postdoc will participate in analysis of samples from the Mid Cayman Spreading Center, Earth’s deepest mid-ocean ridge, with an emphasis on using next generation sequencing tools to determine microbial community structure and functional repertoire at the site. These data will serve as a vital input for models of energy flow through deep-sea hydrothermal systems and help to constrain the pathways and controlling factors for microbially-mediated carbon cycling in subsurface ecosystems fueled by water-rock reactions. The successful applicant must hold a Ph.D. in microbiology, oceanography, or a related field and possess experience with metagenomic datasets, bioinformatics, and molecular biology.

Deep Subsurface Microbial Biogeography and Evolutionary Processes: We invite applications for two postdoctoral positions focusing on the application of single cell genomic analyses to subsurface communities sampled from deep boreholes and mine sites located in Finland, Canada and South Africa. The postdoctoral research associates will be based at the University of the Free State (Bloemfontein, South Africa) and Princeton University (Princeton, NJ, USA) and also spend time working at the Single Cell Genomics Center at the Bigelow Laboratory for Ocean Sciences (Maine, USA). This 2 year research project will involve collection, single cell screening, genome sequencing and bioinformatic comparisons of communities from continental subsurface biospheres. A successful applicant must hold a Ph.D. in microbiology or a related field and have experience in assembly, annotation, and bioinformatics analyses of genomes.

For any of the positions please submit three items to the appropriate contact listed below: (i) a cover letter describing your research goals and your specific motivation to join the project, (ii) a CV, and (iii) contact information for three references, including your Ph.D. supervisor.

High Pressure Microbiology position: Prof. Isabelle Daniel (isabelle.daniel@univ-lyon1.fr)

Applications should be received by March 1, 2012, but will be considered on an ongoing basis.





Ph.D. Opportunities in Molecular Geomicrobiology of the Deep Biosphere

Ph.D. opportunities are available in the molecular geomicrobiology of the deep biosphere in the lab of Matt Schrenk at East Carolina University (North Carolina, USA). The research involves the characterization of high pH (>10), hydrogen and methane-rich ecosystems associated with the serpentinization of ultramafic rocks from the deep Earth and involves multi-disciplinary, international research projects in Canada, Italy, and California. These projects focus on advancing our understanding of the ecology and evolution of microbial communities in the deep biosphere using both molecular and culture-based approaches. Research combines bioinformatics analyses of (meta-) genomic and transcriptomic data with field work and laboratory characterization of novel extremophiles. Applicants with a background in Biology, Earth Sciences, Oceanography, or related disciplines are encouraged to apply.

Applications for the Ph.D. program in Biology at ECU are due April 1, 2012 (http://www.ecu.edu/cs-cas/idpbs/admission.cfm). Please contact Matt Schrenk (schrenkm@ecu.edu) for further information.

Introducing the Habitable Exoplanets Catalog


New from the Planetary Habitability Laboratory at the University of Puerto Rico, Arecibo, the Habitable Exoplanets Catalog is an online database for scientists, educators, and the general public focused on potential habitable exoplanet discoveries. The catalog uses various habitability indices and classifications to identify, rank, and compare exoplanets, including potential satellites or exomoons.

The database suggests over 15 exoplanets and 30 exomoons as potential habitable candidates.

Scientists are now starting to identify potential habitable exoplanets after nearly twenty years of the detection of the first planets around other stars. Over 700 exoplanets have been detected and confirmed with thousands more still waiting further confirmation by missions such as NASA Kepler. Most of these are gas giants, similar to Jupiter and Neptune, but orbiting very dangerously close to their stars. Only a few have the right size and orbit to be considered suitable for any life.

Now the Planetary Habitability Laboratory (PHL) of the University of Puerto Rico at Arecibo (UPR Arecibo) presents a new assessment of the habitability of these worlds as part of its Habitable Exoplanets Catalog (HEC). The catalog not only identifies new potential habitable exoplanets, including exomoons like the Pandora world in the movie Avatar, but also ranks them according to various habitability indices.

Applications and nominations must be postmarked by Monday, February 13, 2012. For guidelines and forms, visit www.loc.gov/loc/kluge/fellowships/NASA-astrobiology.html . Candidates should apply directly using the online form. Nominations should be submitted in writing to scholarly@loc.gov.

The astrobiology chair is a new distinguished senior research position in residence at the Library’s Kluge Center for a period of up to 12 months. This is an appointment made by the Librarian of Congress on the recommendation of a selection committee, which considers both applications and nominations. For the Library’s announcement of the chair, visit http://www.loc.gov/today/pr/2011/11-202.html .

Using the collections and services at the Library of Congress, the chair holder conducts research at the intersection between the science of astrobiology and its humanistic aspects, particularly its societal implications. The astrobiology scholar receives a stipend of $13,500 per month. The tenure is expected to begin in October 2012.

The chair holder is expected to give at least one public presentation in the Washington, D.C. area and to organize workshops, symposia, small conferences or other activities that engage the broader academic community and the public.

The late Dr. Baruch S. Blumberg was the founding director of NASA’s Astrobiology Institute. Blumberg shared the Nobel Prize in Physiology or Medicine in 1976 for discovering the hepatitis B virus and developing a powerful vaccine to fight it, saving countless lives. He also was a founding member of the Library’s Scholars Council, which advises the Librarian of Congress on scholarly matters.

Through a generous endowment from John W. Kluge, the Library of Congress established the Kluge Center in 2000 to bring together the world’s best thinkers to stimulate and energize one another, to distill wisdom from the Library’s rich resources, and to interact with policymakers in Washington.

The Library of Congress, the nation’s oldest federal cultural institution and the largest library in the world, holds nearly 147 million items in various languages, disciplines and formats. The Library serves the U.S. Congress and the nation both on-site in its reading rooms on Capitol Hill and through its award-winning website at www.loc.gov . Many of the Library’s rich resources and treasures may also be accessed via interactive exhibitions on a personalized website at myLOC.gov.

The NASA Astrobiology Program supports research into the origins, evolution, distribution, and future of life in the universe. The NASA Astrobiology Institute (NAI), an element of that program, is a partnership among NASA, 14 U.S. teams, and eight international consortia. NAI’s goals are to promote, conduct, and lead interdisciplinary astrobiology research, train a new generation of astrobiology researchers, and share the excitement of astrobiology with learners of all ages.





Conference on Life Detection in Extraterrestrial Samples

The Conference on Life Detection in Extraterrestrial Samples will be held February 13–15, 2012, at the Scripps Institution of Oceanography, San Diego, California.

Purpose and Scope

The return of samples from Mars was the highest-priority flagship in the U.S. Planetary Decadal Survey. It is also a key element in the European Space Agency's (ESA) Mars Robotic Exploration Preparatory Program to prepare Europe's contribution to the international exploration of Mars. Part of planning for a Mars sample return mission includes planning for what will happen to the samples after they have returned to Earth. One of the major scientific questions that will be asked in the analysis of returned martian samples is whether they contain indications of past or present martian life. In addition, international guidelines and agency policies dictate that Mars samples must be subjected to a program of life detection and biohazard analysis before they can be released from strict containment, to protect the environment of the Earth. A better understanding of current and possible investigation strategies and capabilities, including controls and measurements related to life detection in returned martian samples, is important to address both these concerns.

An understanding of planned or possible life detection strategies and measurements has major implications for several decisions related to requirements for the 2018 sampling rover, including strategies and requirements for avoiding contamination of the samples, and sample size needed to carry out the returned sample measurements.

Life detection strategies and capabilities are relevant to a range of scientific activities beyond Mars sample return, including origin of life investigations of both terrestrial and planetary materials. The search for fossils and remnants of early life on Earth benefits greatly from a variety of analytical techniques, and can inform efforts to detect life in planetary materials. Strategies and technologies for life detection can effectively be applied to meteorite studies, addressing questions regarding the organic constituents present in the early solar system as well as possibly shedding light on reports of possible life in meteorites that remain highly controversial.

Comparative Climatology of Terrestrial Planets

The conference on Comparative Climatology of Terrestrial Planets will be held June 25–28, 2012, at the Hotel Boulderado, located at 2115 Thirteenth Street, Boulder CO 80302.

Comparative Climatology of Terrestrial Planets will explore the differences and similarities between the climates of terrestrial planets in the solar system and beyond. With an emphasis on experimental methods and models, the synergies between Earth science, planetary science, heliophysics, and exoplanet studies will be exploited to identify objectives for future research and missions.

The goal of this conference is to look at climate in the broadest sense possible — by comparing the processes at work on the four terrestrial bodies, Earth, Venus, Mars, and Titan (Titan is included because it hosts many terrestrial processes), and on terrestrial planets around other stars. These processes include the interactions of shortwave and thermal radiation with the atmosphere, condensation and vaporization of volatiles, atmospheric dynamics and chemistry, and the role of the surface and interior in the long-term evolution of climate. Conference talks will compare the scientific questions, methods, numerical models, and spacecraft remote sensing experiments for Earth and the other planets, with the goal of identifying objectives for future research and missions. The conference is an opportunity for planetary scientists to survey current work on the best-studied terrestrial planet, and for climate scientists to reflect on how familiar processes on Earth produce such different outcomes in other “laboratories.”
