Photosynthesis and Photo-Stability of Nucleic Acids in Prebiotic Extraterrestrial Environments [PDF]

open access: green, 2014
Laboratory experiments have shown that the UV photo-irradiation of low-temperature ices of astrophysical interest leads to the formation of organic molecules, including molecules important for biology such as amino acids, quinones, and amphiphiles. When pyrimidine is introduced into these ices, the products of irradiation include the nucleobases uracil,

Predicting Infrared Optical Properties of Materials Using Machine Learning Interatomic Potentials

open access: yesMaterials Genome Engineering Advances, EarlyView.
This work proposes a new fast computing framework for infrared reflectance spectra, MTP‐FIRE, based on machine learning potential, which can achieve the same accuracy as the existing first‐principles calculation, but can be two orders of magnitude faster on average.
