"You don't see radio changing gradually and suddenly become radar. #Darwin's theory doesn't work for #technology, and we have to make a new observation."

"Novel technologies are constructed from existing technologies. These offer themselves as components for the construction of further technologies."

Unlike the two-parent #inheritance typical to (but not ubiquitous among) #complex organisms, #technology inherits features from n parents - a "vast ancestral #network" more like horizontal gene transfer networks in #bacteria.

Yes 👉 And when #bacteria enter the #blood, they are even more likely to infect + persist inside the cells of the immune system 👉 There, the proteins + #metabolites they create can directly modulate the activity of human genes that regulate #metabolism + immune response etc
Also a growing # of organisms can persist in the #blood itself 👉 This @StanfordMed study found 1000s of never before discovered bacteria + #viruses in the blood of immunocompromised patients (99% of microbes identified were previously unknown to science): pnas.org/content/early/…
The team contends these newly discovered microbes 👉 “have potential consequences for human #health. They may prove to be the cause of acute or #chronic diseases that, to date, have unknown etiology”☝️This technology has not yet been used to study blood in conditions like #ME/CFS

Microbes/viruses interact to drive disease 👉 Here, a #bacteriophage (Pf) that infects bacterial pathogen p. aeruginosa (Pa)☝️promoted Pa virulence (in wounds) by triggering maladaptive anti-viral responses in human cells + suppressing bacterial clearance: science.sciencemag.org/content/363/64…
In addition 👉 1. The data suggest that a natural (unmodified) #bacteriophage may be able to produce mRNA within human cells☝️2. Consistent with a pathogenic role for Pf #phage, a vaccine against Pf phage protected against P. aeruginosa wound infections in mice
Simple summary 👉 This marks the first time a #bacteria-infecting #virus, otherwise known as a #bacteriophage...has been observed inducing the immune system to mount an antiviral response and, in doing so, causing it to ignore the bacterial infection: google.com/amp/s/medicalx…
