SummaryDuring the late eighteenth and early nineteenth centuries, the British East India Company monopolized salt production in Bengal, and the British sought a new market for English salt in India. As previous studies have emphasized, external political and economic forces devastated indigenous industry and its workers. However, working conditions were influenced more by the natural environments of the salt-producing localities, particularly the availability of fuel, which was indispensable to the process of manufacture. The industry had always benefitted from abundant grass and straw for use as fuel. However, as grasslands were lost due both to constant river encroachment and to land clearance for cultivation, straw prices increased with the emergence of a regional market for biomass fuels, so that increasing difficulties in procuring fuel gradually made the salt industry costly. That state of affairs was accelerated by the advance of economic activity in general and a shortage of coal in particular. The changes made workers much more dependent on the fuel market.

Gene expression is an intricately regulated process that is at the basis of cell differentiation, the maintenance of cell identity and the cellular responses to environmental changes. Alternative splicing, the process by which multiple functionally distinct transcripts are generated from a single gene, is one of the main mechanisms that contribute to expand the coding capacity of genomes and help explain the level of complexity achieved by higher organisms. Eukaryotic transcription is subject to multiple layers of regulation both intrinsic — such as promoter structure — and dynamic, allowing the cell to respond to internal and external signals. Similarly, alternative splicing choices are affected by all of these aspects, mainly through the regulation of transcription elongation, making it a regulatory knob on a par with the regulation of gene expression levels. This review aims to recapitulate some of the history and stepping-stones that led to the paradigms held today about transcription and splicing regulation, with major focus on transcription elongation and its effect on alternative splicing.

Despite the considerable advances in molecular biology over the past several decades, the nature of the physical–chemical process by which inanimate matter become transformed into simplest life remains elusive. In this review, we describe recent advances in a relatively new area of chemistry, systems chemistry, which attempts to uncover the physical–chemical principles underlying that remarkable transformation. A significant development has been the discovery that within the space of chemical potentiality there exists a largely unexplored kinetic domain which could be termed dynamic kinetic chemistry. Our analysis suggests that all biological systems and associated sub-systems belong to this distinct domain, thereby facilitating the placement of biological systems within a coherent physical/chemical framework. That discovery offers new insights into the origin of life process, as well as opening the door toward the preparation of active materials able to self-heal, adapt to environmental changes, even communicate, mimicking what transpires routinely in the biological world. The road to simplest proto-life appears to be opening up.
