Special Issue Information

Dear Colleagues,

This issue consists of papers at the annual meetings of ILASOL, and related topics. ILASOL, Israel Society for Astrobiology and the Study of the Origin of Life, is an Israeli scientific society devoted to life's origin and early evolution, and to Astrobiology-the potential existence and detection of life in the universe.

ILASOL was established in 1987 and has been a member of FAO (the Federation of Astrobiology Organizations) since January 2005. ILASOL holds an annual gathering every year, in which astronomers, physicists, biologists, chemists, geologists, and researchers of other disciplines present works related to life's origin and astrobiology. Its website, https://www.ilasol.org.il/, has a lot of information on current and past activity.

The current issue has contributions from leading researchers in Israel as well as a few prominent guest scientists from abroad. The contributions are spread over various subjects, such as biology, biochemistry, chemistry, astrobiology, and more.

We dedicate this issue to the memory of Prof. Dan Tawfik, who was killed in a climbing accident in 2021, two weeks after he gave the opening lecture of the meeting.

Prof. Amri Wandel

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Life is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Mixed lipid micelles were proposed to facilitate life through their documented growth dynamics and catalytic properties. Our previous research predicted that micellar self-reproduction involves catalyzed accretion of lipid molecules by the residing lipids, leading to compositional homeostasis. Here, we employ atomistic Molecular Dynamics simulations, beginning with 54 lipid monomers, tracking an entire course of micellar accretion. This was done to examine the self-assembly of variegated lipid clusters, allowing us to measure entry and exit rates of monomeric lipids into pre-micelles with different compositions and sizes. We observe considerable rate-modifications that depend on the assembly composition and scrutinize the underlying mechanisms as well as the energy contributions. Lastly, we describe the measured potential for compositional homeostasis in our simulated mixed micelles. This affirms the basis for micellar self-reproduction, with implications for the study of the origin of life. Full article
