This study aims to reexamine the historical perceptions of the Japanese comic book medium, particularly the "magazine culture" which began in the late I960s, by tracing the historical process of creating "Shinshoban comics" during the 1960s and 1970s. Prior historical studies of postwar manga have not fully examined manga comic magazines, and manga has usually been defined as one type of comic magazine, not as its own independent form of media. Accordingly, in this article, I focus on the "Shinshoban comics" that predated present-day manga comics in order to understand the transformations in the comic industry during the late 1960s and early 1970s. Unlike the manga comics of today, due to the lack of modern industry and marketing systems, Shinshoban comics were very marginalized and crossed over various manga publishing borders. However, as series of Shinshoban comics based on particular comic magazines became the dominant publication style of manga comics, they were gradually perceived to be one type of comic magazine in the comic industry. Moreover, in the political and cultural climate of that time, the publication of some Shinshoban comics was delayed while others were screened out. Some of the works filtered out of the major public companies were published by small publishers as well as Kashihon publishers, which published for book-lending shops. As a result, though Shinshoban comics were subsumed by the comic publishing industry as a part of magazine culture, they were also relatively independent and established themselves as an original publishing medium. Therefore, an investigation of the historical process of creating Shinshoban comics clarifies that the industrialization centering around comic magazines produced by the major publishers beginning in the late 1960s contained within it a complexity that gave rise to an "independent" or "derivative" media culture.

This study aims to consider the historical process of establishing of Manga by focusing on Comic Book Sections in Japanese bookstores from the early 1970s to 1980s. Prior studies on Manga tend to focus on trades outside of regular distribution channels to emphasize peculiar characteristics of the emerging media. Consequently, the social process during the 1970s and 1980s to pervade Manga almost all of the retail bookstores through wholesalers has not been clarified. The article shows how Manga to be recognized as one of the established genre in bookstores by concentrating on the particular standard of shinshoban (pocket paperback edition) comics which became one of the best sellers in retail bookstores after the 1970s. The early spread of permanent section of shinshoban comics during the 1970s can be understood as a conflict between Manga and other genre of books, mostly literal arts, and through industrial change surrounding book business as a background. In the late 1970s, sale structure of the small and medium-sized retail bookstores became more dependent on the shinshoban comics. The situation forced booksellers to redefine the identity of their bookstore represented in the composition of sections. Accordingly, most booksellers decided to redefine the identity of their bookstores as a space for consumption from a space of cultural excellence. Booksellers defined Manga merely as a commodity and accepted shinshoban comics to make up a permanent section in their bookstores to compromise their ideals. However, constructing Manga sections in bookstores was nothing less than legitimizing Manga as one of the established genres of printed books. Therefore, the establishment of Manga in the 1970s and 1980s can be seen as a process of reconsidering the publication culture for the Japanese publication industry in a transitional period.

Estimating the “minimal gene set” for a cell to be viable is an important issue in understanding “living” cells, creating “artificial” cells, and revealing “ancient” cells. The minimal gene set is critical information for understanding a cell system and designing an artificial genome, which is an essential element for creating an artificial cell. Artificial cells can provide many clues to understanding primordial life on Earth. To reveal minimal gene sets, “essential genes” in many bacteria, which could not be removed from bacterial genomes, have been identified. Bacteria are the most useful organisms for identifying essential genes from their specific characteristics: small genomes, rapid growth, and species that are easy to manipulate genetically. Therefore, various investigations on minimal gene sets or minimal genome of bacteria are reviewed, and “the minimal gene set for a viable cell” is discussed.

Previously proposed hypotheses on the origin of life are reviewed and it is demonstrated that none of them can provide the energy flux of ionizing radiation (UV/X/γ photons, and high-energy charged particles and neutrons) required to synthesize organic materials as demonstrated by the experiments by Miller and Urey in 1953. In order to overcome this difficulty, Ebisuzaki and Maruyama, in 2017, proposed a new hypothesis called the “Nuclear Geyser Model” of the origin of life, in which high-energy flux from a natural nuclear reactor drives chemical reactions to produce major biological molecules, such as amino acids, nucleotides, sugars, and fatty acids from raw molecules (H2O, N2, and CO2). Natural nuclear reactors were common on the surface of Hadean Earth, because the 235U/238U ratio was as high as 20%, which is much higher than the present value (0.7%), due to the shorter half-life of 235U than 238U. Ebisuzaki and Maruyama further posited that aqueous electrons and glyceraldehyde play key roles in the networks of chemical reactions in a nuclear geyser and suggested that primordial life depended on glyceraldehyde phosphate (GAP) from the nuclear geyser system as energy, carbon, and phosphate sources, pointing to a possible parallelism with the anaerobic glycolysis pathway; in particular, the lower stem path starting from GAP through Acetyl Coenzyme A to produce ATP and reduction power. It is shown that microbes (members of candidate division OD1) inhabiting high alkali hot springs, a modern analogue of the Hadean Earth environment, do not possess genes associated with conventional metabolisms, such as those of the TCA cycle, but only have genes in the lower stem path of the glycolysis. This is named the “Hadean Primordial Pathway”, because it is believed that this striking result points to a plausible origin of metabolic pathways of extant organisms. Also proposed is a step-by-step scenario of the evolution of the metabolism: 1) Chemical degradation of GAP supplied from the nuclear geyser to lactate; 2) Catalytic reactions to produce reductive power and acetyl coenzyme A (or its primitive form) and self-reproductive reactions by ribozymes on the surface of minerals (pyrite and struvite), which precipitate in a nuclear geyser (RNA world); 3) Enzymatic reactions by proteins with pyrites and the struvite in their reaction centers (RNP world); and, 4) Metabolism of extant organisms with the full assembly of enzymes produced by translating molecular machines with information stored in DNA sequences (DNA world). It is further inferred that relics of primordial metabolic evolution in the Hadean nuclear geyser can be seen at the reaction centers of enzymes of both pyrite and struvite types, nucleotide-like molecules as a cofactor of the enzymes, Calvin Cycle of photosynthesis, and chemical abundance of cytoplasm.
