There is hardly anything more central to our universe than conservation. Many scientific fields and disciplines view the law of conservation as one of the most fundamental universal laws. The Darwinian model pivots the process of evolution on variability, reproduction, and natural selection. Conservation plays a marginal role in this model and is not really universal, as the model allows exceptions to conservation, i.e. non-conservation, to play an equally important role in evolution. This anomalous role of conservation in the Darwinian model raises questions: What is the reason for this anomaly? Is conservation really universal, as we tend to believe or is it not, as the Darwinian model suggests? This contribution proposes a new model of evolution that focuses on levels of organization, rather than of species, organisms, or populations. It argues that conservation is central to evolution. Not only does this new model restores the universal status of conservation but it also makes possible to resolve some outstanding problems and controversies that continue to plague the Darwinian model. The article tries to advance the broad Darwinian project that seeks to explain the process of evolution as a product of the spontaneous processes in nature. Show less

The environmental impacts of waste disposal of polyethylene bags and seasonal variation of polyethylene disposal in Gusau City of Zamfara state, Nigeria was investigated. General public waste disposals from homes, schools and daily markets, were randomly selected for data collection. The data showed that polyethylene waste is generated more in the dry season than the wet season. The result also showed that table water sachet has 75% disposal. This is because, sachet water is cheap and consumed throughout the year with very little seasonal variation while at homes and markets also, displayed a very interesting pattern. The study revealed that in the market, polyethylene for table water sachets (10%) was the least, followed by ice cream sachets (6%), assorted items (5%) and biscuits wrappers (4%). On the other hand, the results showed that, at home, polyethylene for assorted items was the highest (61%), closely followed by biscuit wrappers (20%), table water sachets (14%) and ice cream wrappers (5%) respectively. Polyethylene waste poses various threats to public health and adversely affects flora and fauna as well as the environment especially when it is not appropriately collected and properly disposed. And based on this research, it was found that most of the public do not know the advantages, disadvantages and the health effects of rampant and improper disposal of polyethylene bags. It is concluded that aggressive campaign and enlightenment of the masses on the threats posed by polyethylene bags pollution should be carried out to prevent further negative environmental impact.

As shown earlier, the algorithmic complexity, like Shannon information and Boltzmann entropy, tends to increase in accordance with the general law of complification. However, the algorithmic complexity of most material systems does not reach its maximum, i.e. chaotic state, due to the various laws of nature that create certain structures. The complexity of such structures is very different from the algorithmic complexity, and we intuitively feel that its maximal value should be somewhere between order and chaos. I propose a formula for calculation such structural complexity, which can be called - structuredness. The structuredness of any material system is determined by structures of three main types: stable, dissipative, and post-dissipative. The latter are defined as stable structures created by dissipative ones, directly or indirectly. Post-dissipative structures, as well as stable, can exist for an unlimited time, but at the micro level only, without energy influx. The appearance of such structures leads to the “ratchet” process, which determines the structure genesis in non-living and, especially, in living systems. This process allows systems with post-dissipative structures to develop in the direction of maximum structuring due to the gradual accumulation of these structures, even when such structuring contradicts the general law of complification.  Show less

The coronavirus infectious disease (20)19 (COVID-19) pandemic is caused by a newly identified virus (2019) SARS-CoV-2, a beta coronavirus that shares similarities with other human-infecting coronaviruses. Genomic analysis suggests that SARS-CoV-2 is closely related to SARS-CoV, a bat-related coronavirus, RaTG13, and to other pangolin-associated coronaviruses. The spike protein of coronaviruses are glycoproteins and are responsible for attaching the virus to the host cell and entering. Amino acid changes within the spike protein-encoding gene from SARS-CoV to SARS-CoV-2 enable SARS-CoV-2 to form a stable spike protein, to form a stable complex between the S protein and the receptor ACE2, to increase binding points between the S protein and ACE2, and to survive at higher temperatures. SARS-CoV-2 is zoonotic, with genomic analysis implicating bats as the original host and pangolins as the most likely intermediate host to infect humans. As SARS-CoV-2 infects humans, viral point mutations will continually occur and cause the emergence of new competitive SARS-CoV-2 strains. Two major strains include D614G and N501Y and have increased infectivity and transmission, further complicating the scope of the current COVID-19 pandemic. Vigilant monitoring of viral development and evolution is necessary for developing proper treatment methods and vaccine targets. Show less
