PhD position in Geneva

Applications are invited for a PhD student position at the Department of Astronomy of the University of Geneva to start as soon as possible.

The successful candidate will be member of the research group led by Dr. Marc Audard in the field of star and planet formation. The PhD student will work on a project to study the episodic accretion phenomenon in star and planet formation using observational data (proprietary and archival), by modelling them using thermochemical codes, and by comparing with theoretical models developped at the Department of Astrophysics at the University of Vienna, Austria (Dr. Eduard Vorobyov and Prof. Manuel Guedel).

Postdoc position: Prebiotic chemistry (Computational), Sorbonne, Paris

An 18-months postdoctoral position is offered at the Université Pierre et Marie Curie – Sorbonne of Paris, under the supervision of Profs. A. Marco Saitta and Fabio Pietrucci.

The project, focused on advanced ab initio free-energy methods (metadynamics and beyond) to model the synthesis of fundamental biochemical bricks under realistic prebiotic conditions, will develop within a larger research consortium. This includes the experimental groups of Profs. M.-C. Maurel (Muséum National d'Histoire Naturelle), J.-F. Lambert and T. Georgelin (Chemistry Department of UPMC), and F. Guyot (Institut de Minéralogie, de Physique des Matériaux et de Cosmochimie), all in Paris. The fellowship, funded by the Sorbonne Excellence Cluster "MATISSE" (MATerials, InterfaceS, Surfaces, Environment), should start in 2016, at the earliest convenience.

River of Time

The RIVER of TIME is an exhibition that retraces the major stages of the history of our planet since the formation of the Solar System---4.57 billion of years ago---until the emergence of Homo sapiens---200,000 years ago---through the development and diversification of life on Earth.

It is a series of panels, freely downloadable from RIVER of TIME.

Emergent Chemical Behavior in Variable-Volume Protocells

Artificial protocellular compartments and lipid vesicles have been used as model systems to understand the origins and requirements for early cells, as well as to design encapsulated reactors for biotechnology. One prominent feature of vesicles is the semi-permeable nature of their membranes, able to support passive diffusion of individual solute species into/out of the compartment, in addition to an osmotic water flow in the opposite direction to the net solute concentration gradient. Crucially, this water flow affects the internal aqueous volume of the vesicle in response to osmotic imbalances, i

Constraining planet structure from stellar chemistry: the cases of CoRoT-7, Kepler-10, and Kepler-93

We explore the possibility that the stellar relative abundances of different species can be used to constrain the bulk abundances of known transiting rocky planets. We use high resolution spectra to derive stellar parameters and chemical abundances for Fe, Si, Mg, O, and C in three stars hosting low mass, rocky planets: CoRoT-7, Kepler-10, and Kepler-93. These planets follow the same line along the mass-radius diagram, pointing toward a similar composition. The derived abundance ratios are compared with the solar values.

Ultrastructural Heterogeneity of Carbonaceous Material in Ancient Cherts: Investigating Biosignature Origin and Preservation

Opaline silica deposits on Mars may be good target sites where organic biosignatures could be preserved. Potential analogues on Earth are provided by ancient cherts containing carbonaceous material (CM) permineralized by silica. In this study, we investigated the ultrastructure and chemical characteristics of CM in the Rhynie chert (c. 410 Ma, UK), Bitter Springs Formation (c. 820 Ma, Australia), and Wumishan Formation (c. 1485 Ma, China). Raman spectroscopy indicates that the CM has experienced advanced diagenesis or low-grade metamorphism at peak metamorphic temperatures of 150–350°C. Raman mapping and micro-Fourier transform infrared (micro-FTIR) spectroscopy were used to document subcellular-scale variation in the CM of fossilized plants, fungi, prokaryotes, and carbonaceous stromatolites.

Stability and its manifestation in the chemical and biological worlds

Bridging between the phenomenologically distinct biological and physical worlds has been a major scientific challenge since Boltzmann's probabilistic formulation of the second law of thermodynamics. In this review we summarize our recent theoretical attempts to bridge that divide through analysis of the thermodynamic-kinetic interplay in chemical processes and the manner in which that interplay impacts on material stability. Key findings are that the term ‘stability’ manifests two facets – time and energy – and that stability's time facet, expressed as persistence, is more general than its energy facet.

Astrobiology from early-career scientists' perspective

What is astrobiology? Which fields does it comprise and what makes an astrobiologist? Ask five scientists and you may end up with six different definitions. This issue was raised at the first symposium of the European network of Astrobiology Graduates (AbGradE), held last year in Edinburgh, when discussing whether the attendees' fields of study were represented in the astrobiology community.

Short Term Scientific Missions (STSMs)

Aiming at fostering collaboration, sharing new techniques, and infrastructure that may not be available in other participants' institutions or laboratories. STSMs are intended especially for young PhD researchers, but they are open to senior researchers as well. View the documents at this link.

 It should be explicitely noted that Master students are not eligible for STSMs which are for PhD students and more experienced researchers.

The life-Origins COST Project


Life-ORIGINS (TD1308) is a Trans Domain European COST Action dedicated to the scientific investigation of the origins and evolution of life on Earth and habitability of other planets.

The Action has specifically excluded the search for intelligent extraterrestrial life in its portfolio. Creationist theorems are also outside the Action’s remit.

Individuals are not allowed to use the name of the Action, its logo or any corporate identity of COST TD1308 in any communication without prior approval of the Management Committee.

All publications referencing the support of the Action should be sent to the appropriate Working Group chair at the time of submission.
