A lot of brain diseases are proving difficult to treat due to the “blood-brain barrier”[1]. Could this bacteria be genetically modified to achieve this purpose? If so, the bacteria, when absorbed through the gums could be used benevolently to provide treatment for all sorts of brain diseases.
Something else to consider - what if the reason these plaques are unable to be cleaned out in some is the result of a life (decades)-long “deep” sleep deprivation (i.e, still getting sleep but not a good amount of regular, deep sleep where this cleaning process would normally occur), and the reason for this chronic sleep deprivation was some genetic pre-disposition, such as bruxism, which would cause little to no “deep sleep,” or perhaps brought on form of chronic dehydration due to a genetic predisposition for diabetes / sugary drinks / blood sugar imbalance, causing brain fogginess rather than deep sleep during a period of involuntary fasting, or a myriad of other unnoticeable deep- sleep-depriving illnesses?
I am not suggesting I have any answers; only questions and curiosities for the puzzling subject.
This is simply a disagreement between content publishers and content distributors. When a big satellite TV provider acted unfavorably toward a few major television networks during contract (re)-negotiation, those select few decided not to renew their license with the satellite TV company, causing viewers to ask why they can't get their favorite channel that their neighbor still gets.
The internet works similarly in that an electronic contract is formed when an ISP attempts to access content on web server. The client/ISP "requests" the content, and the publisher agrees and serves it up. But there's nothing stopping a collective "big few" from denying access to the content based on the host name of the ISP requesting it.
Ergo, if Verizon doesn't want to play "fair" with regards to content distribution, Facebook/Google/Twitter/Netflix/Reddit and whomever else could deny access to Verizon subscribers with an ol fashioned HTTP 403 or 401.
Yes, traffic drops, people realize quickly that they can't access any of their favorite sites, things must be broken, and switch companies.
