From Cosmos to Intelligent Life: The Four Ages of Astrobiology

open access: yes, 2012
The history of life on Earth and in other potential life-bearing planetary platforms is deeply linked to the history of the universe. Since life as we know it relies on chemical elements forged in dying heavy stars, the universe needs to be old enough ...

DNA nanotechnology: new adventures for an old warhorse [PDF]

open access: yes, 2017
As the blueprint of life, the natural exploits of DNA are admirable. However, DNA should not only be viewed within a biological context. It is an elegantly simple yet functionally complex chemical polymer with properties that make it an ideal platform ...

Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment

open access: yesChemSystemsChem, Volume 8, Issue 2, March 2026.
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

Molecular basis of Arginine and Lysine DNA sequence-dependent thermo-stability modulation.

open access: yesPLoS Computational Biology, 2022
We have used a variety of theoretical and experimental techniques to study the role of four basic amino acids-Arginine, Lysine, Ornithine and L-2,4-Diaminobutyric acid-on the structure, flexibility and sequence-dependent stability of DNA.

Valuing life detection missions

open access: yes, 2018
Recent discoveries imply that Early Mars was habitable for life-as-we-know-it; that Enceladus might be habitable; and that many stars have Earth-sized exoplanets whose insolation favors surface liquid water. These exciting discoveries make it more likely

A Solution to the Challenge of Optimization on ''Golf-Course''-Like Fitness Landscapes [PDF]

open access: yes, 2013
Genetic algorithms (GAs) have been used to find efficient solutions to numerous fundamental and applied problems. While GAs are a robust and flexible approach to solve complex problems, there are some situations under which they perform poorly.

Life's Chirality From Prebiotic Environments

open access: yes, 2012
A key open question in the study of life is the origin of biomolecular homochirality: almost every life-form on Earth has exclusively levorotary amino acids and dextrorotary sugars. Will the same handedness be preferred if life is found elsewhere?
