As for myself, I will pick up articles in prebiotic chemistry, virology as it relates to retroviruses or bacterial viruses, or molecular biology, such as those dealing with new discoveries related to promoters, transcription factors (proteins and RNAs which regulate the expression of other proteins and RNAs by binding to promoters), but even after having read a fair amount, trying to fit together pieces in a puzzle, I will be lucky if I have actually understood more than half of a given article at a relatively basic level.
