The Abiogenesis Timescale

open access: yes
If two physical timescales are independent, i.e. they depend on different physics, then (statistically) there is no reason to believe that their values should be equal, even to an order of magnitude. The timescale for abiogenesis $τ_{AB}$, which depends primarily on prebiotic-chemistry, is expected to be independent of the planetary habitability ...

Prebiotic formation of thioesters via cyclic anhydrides as a key step in the emergence of metabolism

open access: yesScientific Reports
Thioesters are high-energy derivatives of carboxylic acids that are essential in the functioning of today’s living cells. Their central role argues in favor of their early introduction in the abiotic reaction network which led to the emergence of life on

Complexity, Information and Biological Organisation [PDF]

open access: yesInterdisciplinary Description of Complex Systems, 2005
Regarding the widespread confusion about the concept and nature of complexity, information and biological organization, we look for some coordinated conceptual considerations corresponding to quantitative measures suitable to grasp the main ...

Photochemical synthesis of natural lipids in artificial and living cells

open access: yesNature Communications
Lipid synthesis plays a central role in cell structure, signaling, and metabolism. A general method for the abiogenesis of natural lipids could transform the development of lifelike artificial cells and unlock new ways to explore lipid functions in ...
