Acrylic acid (CH2CHCOOH): the rotational spectrum in the millimetre range up to 397 GHz

In order to facilitate its detection in astronomical observations, the measurement of the rotational spectrum of acrylic acid has been extended to 397 GHz using a free space cell at room temperature. 295 new lines were assigned to the s-cis conformer and 286 new lines to the s-trans conformer of acrylic acid. Using the determined experimental parameters, the predictions of the rotational transition frequencies up to 900 GHz and their intensities were obtained at temperatures of 100 and 200 K and at room temperature.

The Millimeter Wave Spectrum of the Weakly Bound Complex CH2=CHCNH2O: Structure, Dynamics and Implications for Astronomical Search

The weakly bound 1:1 complex between acrylonitrile (CH2=CHCN) and water has been characterized spectroscopically in the millimeter wave range (59.6-74.4 GHz) using a Free Jet Absorption Millimeter Wave spectrometer. Precise values of the rotational and quartic centrifugal distortion constants have been obtained from the measured frequencies of the normal and isotopically substituted water moiety (DOH, DOD, H18OH).

Biological regulation: controlling the system from within

Biological regulation is what allows an organism to handle the effects of a perturbation, modulating its own constitutive dynamics in response to particular changes in internal and external conditions. With the central focus of analysis on the case of minimal living systems, we argue that regulation consists in a specific form of second -order control , exerted over the core (constitutive) regime of production and maintenance of the components that actually put together the organism. The main argument is that regulation requires a distinctive architecture of functional relationships, and specifically the action of a dedicated subsystem whose activity is dynamically decoupled from that of the constitutive regime.

The Activation of Free Dipeptides Promoted by Strong Activating Agents in Water Does not Yield Diketopiperazines

The activation of dipeptides was studied in the perspective of the abiotic formation of oligopeptides of significant length as a requirement for secondary structure formation. The formation of piperazin-2,5-diones (DKP), previously considered as a dead end when activating free dipeptides, was shown in this work to be efficiently suppressed when using strong activating agents (e.g., carbodiimides). This behaviour was explained by the fast formation of a 5(4H)-oxazolone intermediate at a rate that exceeds the time scale of the rotation of the peptide bond from the predominant trans-conformation into the cis-isomer required for DKP formation.

From stellar to planetary composition: Galactic chemical evolution of Mg/Si mineralogical ratio

The main goal of this work is to study element ratios that are important for the formation of planets of dierent masses. Our results demonstrate the importance of Galactic chemical evolution and indicate that it may play an important role in the planetary internal structure and composition. The results also show that abundance ratios may be a very relevant issue for our understanding of planet formation and evolution.

Europlanet 2020 Research Infrastructure

The Europlanet 2020 Research Infrastructure (RI) is a project to integrate and support planetary science activities across Europe. The project is funded under the European Commission’s Horizon 2020 programme; it was launched on 1st September 2015 and will run until 31 August 2019. The project has 34 beneficiary institutions from 19 European countries. Europlanet 2020 RI will address key scientific and technological challenges facing modern planetary science by providing open access to state-of-the-art research data, models and facilities across the European Research Area.

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.
