From the table of the standard genetic code at 64 codons, 61 amino acids and 3 Stop signals, It is invested a simplified matrix of the genetic code comprising only twice twenty entities: the twenty canonical proteinogenic amino acids associated with only twenty DNA biplets. By this process, a singular organization of this matrix is highlighted in both symmetrical and asymmetrical arrangements. Also, the configurations of this matrix are organized in coincidence with the alphanumeric system introduced in a recent published article by the author. This compressed version of the genetic code is called "the ultimate genetic code matrix."

Prigogine’s 1978 concept of dissipative structures, drawing parallels with living systems, forms the basis for exploring life’sunique traits. However, these identified similarities prove insufficient in capturing the entirety of life. To address this gap, ourproposed modeling approach emphasizes the distinctive ability of living organisms to observe other systems—an attributeintricately tied to quantum mechanics’ "measurement" processes, as highlighted by Howard Pattee. This article introduces acomprehensive mathematical model centered on quantum dynamical dissipative systems, portraying living systems as entitiesdefined by their observational capacities within this framework. The exploration extends to the core dynamics of these systemsand the intricacies of biological cells, including the impact of membrane potentials on protein states. Within this theoreticalstructure, the model is expanded to multicellular living systems, revealing how cells observe quantum dynamical systemsthrough protein state changes influenced by membrane potentials. The conclusion acknowledges the current theoreticalstatus of the model, underscoring the crucial need for experimental validation, particularly regarding the superposition state ofmembrane proteins under the influence of an electric field.

Almost all phenomena and structures in nature exhibit some degrees of fractionality or fractality. Fractional calculus and fractal theory are two interrelated concepts. In this article we study the memory effects in nature and particularly in biological structures. Based on this fact that natural way to incorporate memory effects in the modeling of various phenomena and dealing with complexities is using of fractional calculus, in this article we present different examples in various branch of science from cosmology to biology and we investigate this idea that are we able to describe all of such these phenomena using the well-known and powerful tool of fractional calculus. In particular we focus on fractional calculus approach as an effective tool for better understanding of physics of living systems and organism and especially physics of cancer.

Following our previous works on fractional biophysical issues such as fractional dynamics of protein folding process and fractional dynamics of cancer cells and their branching processes, in this work we further develop these issues and propose a new fractional biomechanics of cancer cells. In this study we present some promising models for future studies in biomedicine, including constant and variable order fractional Maxwell and Kelvin—Voigt models to study the mechanics of cancer cells. We also emphasize that fractional calculus will play a vital and central role in the understanding of the complexities that occur when we deal with the phenomena and processes in the realm of bioscience and biomedicine and particularly in physics of cancer.

Understanding biological complexity is one of the most important scientific challenges nowadays. Protein folding is a complex process involving many interactions between the molecules. Fractional calculus is an effective modeling tool for complex systems and processes. In this work we have proposed a new fractional field theoretical approach to protein folding. We have derived two coupled fractional partial differential equations that their solutions with specific boundary conditions and different values of the order of fractional derivative would describe and predict the possible contour of conformational changes for protein folding.

We look into the Age(in years) vs Amplitude of accommodation(in Diopters) of eye. We draw the natural logarithm of the age, normalised, starting with an amplitude of accommodation of an eye vs the natural logarithm of the the amplitude of accommodation of the eye, normalised. We conclude that the Age vs Amplitude of accommodation of eyes, can be characterised by a magnetisation curve of a Spin-Glass in the presence of a little external magnetic field.

Homochiral biology can be recognized as the outcome of an ancestral breaking of chiral symmetry which has subsequently propagated through a broadening range of descendant dynamic networks. Recently published research provisionally accounts for the establishment of biological homochirality by demonstrating that the chiral symmetry of ribo-aminooxazoline (RAO) in racemic solution is broken by exclusive adsorption of D-RAO, a precursor of RNA, on to a naturally-magnetized mineral surface (magnetite). This proposed mechanism in the prebiotic environment would allow for subsequent unidirectional propagation of homochirality through homochiral RNA to homochiral peptides (including enzymes) to homochiral metabolism. Noting these recent chemical and physical results, I show that an origin out of broken chiral symmetry and subsequent homochiral replication of the Byl cellular automata replicator (1989) can be seen as an analogy to the origin and propagation of biological homochirality.
