Toxoplasma, RhD and risk taking.

(Image credit: Christoph Hohmann, Nanosystems Initiative Munich (NIM)) Did Schrodinger's Cat have toxoplasmosis? One may well ask what does a widespread protozoan parasite have to do with either the poison, the radioactive source or the ultimate survival of a cat in an experimental box? While it appears counter-intuitive and has nothing whatsoever to do with quantum superposition or entanglement, I can none the less suggest that the poison and stochastic nature of the radioactive source are far less important to the outcome of the “experiment” than Schrodinger’s choice of cat food. While it is obvious that the amount and half-life of the radioactive source determines the probability of the cat’s survival, the effect of both Schrodinger and his cat’s behavior are rarely considered despite the discovery of  a  prehistoric link  between felines and their mammalian prey. To quote Schrodinger: “A cat is penned up in a steel chamber, along with the following device (which must ...

Questioning ChatGPT about SARS-CoV-2, HCoV-OC43 and OAS1

Given the possibility that the Omicron variant arose following template switching in a cell co-infected with HCOV-229E, write a story about what might happen with COVID-19 following SARS-COV2 template switching with HCOV-OC43, having regard to the role of the human gene OAS1. Once upon a time, in the microscopic world of viruses, a new chapter was about to unfold. The notorious SARS-CoV-2 virus, the causative agent of COVID-19, found itself in a cell already infected with another coronavirus, HCoV-OC43². This was not an ordinary encounter, but a meeting that could potentially change the course of the pandemic. HCoV-OC43, a member of the species Betacoronavirus 1, is known to infect humans and cattle². Unlike SARS-CoV-2, HCoV-OC43 does not lead to severe respiratory syndromes¹. However, its core single-stranded RNA sequence comparably depends on host components for its successful life cycle¹. In this co-infected cell, a phenomenon known as template switching occurred. This is a normal p...

Question If the majority of people wanted to ignore a pandemic, would that be acceptable? No, it would not be acceptable for the majority of people to ignore a pandemic. Pandemics are public health crises that can have significant negative consequences for individuals and society as a whole. Ignoring a pandemic can lead to increased rates of illness, death, and economic disruption, among other negative outcomes. In a democratic society, decisions about public health and safety should be based on the best available scientific evidence and the expertise of public health professionals. While it is important to take into account the views and opinions of the public, decisions about how to respond to a pandemic should ultimately be guided by the need to protect public health and safety. If the majority of people were to ignore a pandemic, it would be the responsibility of public health officials and other authorities to communicate the risks and consequences of such behavior, and to take st...
