# life: apropos of saliva healers, herd immunity revisited and now hypothetically approachable even within NIH

<< President-elect Donald Trump is tapping Dr. Jay Bhattacharya, a Stanford University health researcher, to be the next director of the National Institutes of Health (NIH). >>
<< Bhattacharya was one of three authors of the document (#1). The declaration called for speeding herd immunity by allowing people at low risk to get infected while protecting those most vulnerable, like the elderly. >>

<< The most compassionate approach that balances the risks and benefits of reaching herd immunity, is to allow those who are at minimal risk of death to live their lives normally to build up immunity to the virus through natural infection, while better protecting those who are at highest risk. We call this Focused Protection. >>

From my point of view 'herd immunity'  can be engineered if and only if, even in the case of sars-covid-19 or flu, simultaneous protection is used with an effective, easy available, antiviral drug.

In this regard, a non-compassionate but logical easy approach could be the indirect inhalation of alcohol ~70% already at the first signs of rhinorrhea, as follows:

(-) start self-treatment (spray plus cotton mask):

(-) outcomes

Ultimately, here it could hypothesize a case of historic, singular checkmate of 'one against all'. Anzicheforse?

PS: I couldn't say why, but in certain contexts, the incipit of an answer that the physicist Enrico Fermi https://it.m.wikipedia.org/wiki/Enrico_Fermi  gave to a journalist always comes back to my mind: 'the physics that is done in our laboratory ...' . 

An example of exceptional, clear, even poetic analysis and synthesis skills (in only 8 words).

# gst: apropos of diffusive anomalies, anomalous diffusion of active Brownian particles in responsive elastic gels.

Here, AA << examine via extensive computer simulations the dynamics of SPPs (self-propelled particles) in deformable gellike structures responsive to thermal fluctuations. (AA) treat tracer particles comparable to and larger than the mesh size of the gel. (They) observe distinct trapping events of active tracers at relatively short times, leading to subdiffusion; it is followed by an escape from meshwork-induced traps due to the flexibility of the network, resulting in superdiffusion. >>

AA << thus find crossovers between different transport regimes. (They) also find pronounced nonergodicity in the dynamics of SPPs and non-Gaussianity at intermediate times. The distributions of trapping times of the tracers escaping from “cages” in (..)  quasiperiodic gel often reveal the existence of two distinct timescales in the dynamics. At high activity of the tracers these timescales become comparable. >>

<< Furthermore, (AA) find that the mean waiting time exhibits a power-law dependence on the activity of SPPs (in terms of their Péclet number). (Their) results additionally showcase both exponential and nonexponential trapping events at high activities. Extensions of this setup are possible, with the factors such as anisotropy of the particles, different topologies of the gel network, and various interactions between the particles (also of a nonlocal nature) to be considered. >>
