Plenary Speaker: Prof. Lisa Yaszek

Talk Title: A Brief History of Astrobiology Science Fiction, 5BCE–Present

Abstract: In this talk, Regents Professor of Science Fiction Studies Dr. Lisa Yaszek demonstrates how science fiction artists anticipate, dramatize, and extend our ideas about astrobiology. After briefly reviewing astrobiology themes in ancient and medieval world literature, Dr. Yaszek explores three aspects of this discipline that fascinate modern scientists and speculative artists alike: exobiology, the origins of life, and planetary habitability. She concludes by considering the increasingly global and self-reflexive nature of recent astrobiology stories across media. 

 

Bio: Lisa Yaszek is Regents’ Professor of Science Fiction Studies in the School of Literature, Media, and Communication at Georgia Tech. Her books include Galactic Suburbia: Recovering Women’s Science Fiction (Ohio State, 2008); Sisters of Tomorrow: The First Women of Science Fiction (Wesleyan 2016); and Literary Afrofuturism in the Twenty-First Century (co-edited with Isiah Lavender III, Ohio State, 2020). Yaszek ideas have been featured in The Washington Post, Food and Wine Magazine, and USA Today, and she has been an expert commentator for the BBC4’s Stranger Than Sci Fi, Wired.com’s Geek’s Guide to the Galaxy, and the AMC miniseries James Cameron’s Story of Science Fiction.

Space Science Week @Tech is here! Join the festivities for the Perseverance Landing!

Events

Welcome to Space Science week at Georgia Tech!  Georgia Tech’s Center for Space Tecnology and Research and the ExplOrigins team–our GT Early career Astrobiology community–are teaming up to bring you a fantastic week of events and information about the Red Planet, and the history and exploration of our solar system.  We’re excited to showcase some of the exciting work being done here at Tech, and help celebrate the landing of NASA’s Perseverance Rover on Mars this Thursday!
Each day, we’ll send out some Mars Minutes to help you get informed and excited for the big events this Wednesday through Friday.  The schedule follows below.

Today’s Mars Minute is a rundown of the Mars 2020 mission and the Perseverance Rove
Every two years, the orbits are right to send a mission to Mars.  With the Mars 2020 mission, the goal is to start the ambitious Mars Sample Return program.  The Mars 2020 Perseverance Rover will search for signs of ancient microbial life, which will advance NASA’s quest to explore the past habitability of Mars. The rover has a drill to collect core samples of Martian rock and soil, then store them in sealed tubes for pickup by a future mission that would ferry them back to Earth for detailed analysis. Perseverance will also test technologies to help pave the way for future human exploration of Mars. Strapped to the rover’s belly for the journey to Mars is a technology demonstration — the Mars Helicopter, Ingenuity, may achieve a “Wright Brothers moment “ by testing the first powered flight on the Red Planet.

Plenary Speakers

Dr. Christopher E. Carr

The synthesis of complex organic molecules, including the building blocks of life as we know it, occurs in stellar nebulas, in reducing planetary atmospheres, and through aqueous reaction networks. To the extent that this chemistry is universal, life elsewhere may also utilize amino acids, and nucleic acids or related informational polymers (IPs) for information storage and heredity.

Earth and Mars have exchanged an estimated billion tons of rock due to large meteorite impacts. If life exists on Mars, it could be related to us. Such an assumption is unlikely to hold for any life within Saturn’s moon Enceladus, or at Jupiter’s moon Europa. Here we describe progress towards life detection beyond Earth via single molecule sequencing of nucleic acids: a Search for Extra-Terrestrial Genomes (SETG). We also describe preliminary work to develop the Electronic Life-detection Instrument for Enceladus/Europa (ELIE), which would utilize nanogaps as a solid-state single molecule detector that is agnostic to the precise target chemical identity, extending detection capabilities from life as we know it to life as we don’t know it.

Dr. Mariel Borowitz

The field of astrobiology, with roots more than 100 years old, evolved quickly after the establishment of the National Aeronautics and Space Administration (NASA). This talk explores how the evolution of the field was influenced not only by important developments in science and technology, but also by political and policy issues and decisions. It traces the development of the field over the last sixty years and ends with some discussion of new directions going forward.

Presentations

Dr. Micah Schiable — Chemistry and Biochemistry

The distribution of material throughout our Solar System can place strong constraints on the possible dynamical and thermal histories of small bodies. Only by obtaining a measurement of the large-scale compositional distribution in various regions of the Solar System can questions regarding the origins and history of many small bodies begin to be addressed. Additionally, having a means to rapidly characterize the elemental compositions of bodies could help identify valuable resources for exploration and in situ resource utilization purposes.
The composition of bodies can only be loosely constrained using typical reflected light spectroscopy techniques. Although sample return is the best means of determine details of composition and formation conditions for bodies, it is costly, risky, and limited to a small number of sampling locations. A robust and sensitive technique for obtaining elemental composition of surfaces in high vacuum environments is the collection and analysis of secondary ions ejected due to solar wind and magnetosphere ion sputtering and meteorite impacts. First proposed for space based compositional analysis over 30 years ago [Managadze and Sagdeev, 1988; Johnson and Baragiola, 1991], this technique is commonly known in the laboratory as SIMS and can achieve excellent signal to noise ratios due to low ion backgrounds and high detection sensitivities achievable. Additionally, SIMS measurements at small bodies can help resolve whether these bodies harbor any potentially valuable resources for future exploration missions and how the composition of rocky asteroids varies throughout the Solar System.

Kelvin Smith — Chemical and Biomolecular Engineering

My research focuses on the investigation of the relevant kinetic mechanisms of chiral depsipeptide polymerization and degradation. Once these depsipeptide mechanisms are identified, you can predict behavior of similar peptides used to create biopolymers for pharmaceutical purposes such as drug delivery and tissue engineering. The model provides helpful predictions for future synthesis of other depsipeptides, and it consists of a complex Kinetic Monte Carlo (KMC) framework that simulates growth and degradation of chiral depsipeptides. To use the framework, rate constants of relevant mechanisms must be known a priori through either experimental data or a literary search. To investigate the kinetic mechanisms of ester reactions in depsipeptides, high performance liquid chromatography (HPLC) data of two test molecules are collected and quantified at different pH values and temperatures: multiple oligomers of an HO-dipeptide called glycolic acid alanine (gA) and a methylated molecule of the gA dimer called propionic acid alanine glycolic acid alanine ((PA)AgA). I model and simulate the evolution and degradation of gA using MATLAB to extract rate constants. These degradation rate constants come from a novel model structure that describes two hypothesized mechanisms: scission and backbiting. I perform statistical procedures to determine how good the model fits are to the data, how likely one mechanism describes a model over another, and how confident we can be in the predicted values. Preliminary results show that both scission and backbiting rate constants of the gA oligomers and (PA)AgA follow an Arrhenius relationship and that backbiting is a dominant degradation mechanism at basic pH values in gA oligomers. When the rate constants were plotted against pH, similar behavior can be found in the literature.

Petar Penev — Biological Sciences

The ribosome’s common core connects all life back to a common ancestor and serves as a window to relationships among organisms. In eukaryotes, the common core contains expansion segments (ES’s) that vastly increase ribosomal RNA size. Supersized ES’s have not been observed previously in Bacteria or Archaea, and the origin of eukaryotic ES’s remains enigmatic. We discovered that the large subunit rRNA of Lokiarchaeota, the closest modern cell lineage to the last common ancestor of Archaea and Eukarya, bridges the gap in size between prokaryotic and eukaryotic rRNA. The long large subunit rRNA in Lokiarchaeota is largely due to the presence of two eukaryotic-like, supersized ES’s, ES9 and ES39, which are transcribed in situ. We applied computational models, covariation analysis, and chemical footprinting experiments to study the structure and evolution of Lokiarchaeota ES9 and ES39. We also defined the eukaryotic ES39 fold for comparison. We found that Lokiarchaeota and eukaryotic ES’s are structurally distinct: Lokiarchaeota ES39 has more and longer helices than the eukaryotic ES39 fold. Despite their structural differences, we found that Lokiarchaeota and eukaryotic ES’s originated from a common ancestor that was “primed” for evolution of larger and more complex rRNAs than those found in Bacteria and other archaea.

Dr. Anthony Burnetti

Phototrophy – the ability of a cell to capture light energy for metabolism – is responsible for the vast majority of biomass production and metabolic flux on Earth, and its origin represents an extremely important evolutionary transition. This capability has evolved independently exactly twice in Earth’s history, via chlorophototrophic and retinalophototrophic machinery. Close examination of the properties of these metabolic pathways reveals them to be remarkably complementary in their chemical makeup and ecological roles, suggesting that their properties are the result of ancient ecological interactions between incumbent and novel phototrophs filling initially vacant ecological niches rather than being the random results of rare, difficult innovations. Each origin of phototrophy has filled a particular niche in the tradeoff between efficiency per unit light and efficiency per unit protein infrastructure, and has suppressed the evolution of novel machineries like themselves while failing to suppress each other due to their fundamental architectural differences.

As a “dual evolutionary singularity”, phototrophy can also be used as a touchstone to understand the dynamics of major evolutionary innovations and transitions in the history of life on Earth. Many innovations, such as the singular origin of eukaryotes or the origin of life itself, occurred exactly once and transformed the planet. Others, like the evolution of multicellularity, have occurred many times. This could be due to some innovations being intrinsically rare or difficult, or evolutionary singularities could be singular as a result of ecological interactions by first-movers suppressing innovation by other lineages. The example of phototrophy suggests that many of these singularities could be simpler to evolve than they seem, and could be common in other biospheres.

Aaron Pital

The pace of publication in the sciences has long since outstripped human ability to read and synthesize information. While interdisciplinary work can mitigate some of this burden, there remain fundamental questions about whether attentional blindness and the opportunity cost of reaching beyond the comfort of one’s expertise hold back innovation in speculative fields such as the origins of life. We present a brief model of associative information in scientific publication and propose tools derived from information theory, natural language processing, and data science to search for physical and chemical contexts embedded in literature from fields as diverse and non-traditional as soil science and drug design. The goals of these efforts are 1) to identify physical and chemical information of interest to origins of life researchers which would otherwise be unlikely to rise to the community’s attention and 2) to define rules for correlated information generally to improve literature cataloging, referencing and retrieval.

2020 Exploration and Origins Colloquium:

This interdisciplinary colloquium will highlight space exploration science and origins research going on at the Georgia Institute of Technology, as well as neighboring universities. The goals of the colloquium are to forge relationships between diverse individuals, encourage collaboration and interdisciplinary understanding, and kick-start future fundable projects requiring the skills and expertise of multi-lab teams.

  As previously, the colloquium will be roughly split into two sections: Exploration and Origins. While outlines of the two sections are provided below, the scope of abstracts considered will be broad. Past submissions have been from the departments of Earth and Atmospheric Sciences, Chemistry & Biochemistry, Biology, Physics, Mathematics, and multiple engineering departments.  We emphasize that all interested parties are welcome regardless of discipline or affiliation.  Exploration: For the Exploration session, we are particularly interested in submissions that deal with any and all aspects of reaching beyond to explore the nature of diverse environments. Examples include space technology development, spacecraft mission design, planetary science modeling, biological or ecological fieldwork and direct observations of extrasolar systems; in short, exploring what is  ‘out there’, wherever ‘there’ is. Origins: Submissions for the Origins session are encouraged to include some aspect of reaching back to understand the nature of the world today. Examples include cosmology and the origins of life itself, the emergence of multicellularity, the evolution  of  minerals, complex chemistry, atmospheres, and biological molecules or processes, and the formation of  planetary systems; basically, how did we get here?

Building on the success of the 2018 Astrobiology Colloquium, Georgia Tech Astrobiology and ExplOrigins groups are proud to announce the 2019 Exploration and Origins Colloquium, which will take place on March 28-29, 2019. This is the 2nd annual networking event under the theme of exploring the universe and origins of life.

This year the colloquium is split in two sections: the first section is focused on space exploration technology and planetary science, and the second is oriented toward the chemistry and biology of the origins and the search for life. The event will consist of presentations and talks by early career scientists, i.e. graduate and undergraduate students, and post-doctoral fellows, working in the exciting fields of space and planetary science, engineering and astrobiology across Georgia Tech campus and the greater Atlanta. There will also be plenary lectures given by distinguished members of the global astrobiology community. The objective of this interdisciplinary colloquium is to forge connections across the kinds of research at Georgia Tech straddling the boundaries between technology development and hypothesis testing in the search for life’s beginnings and to explore collaborative ideas among participants. Hence, senior researchers and faculty are also highly encouraged to attend.
