# s-chem: a viscoelastic tongue with reversible saliva (spit and softness) to hang on to the next meal

<< A frog uses its whip-like tongue to snag its prey faster than a human can blink, hitting it with a force five times greater than gravity >>

<< A frog's saliva is thick and sticky during prey capture, then turns thin and watery as prey is removed inside the mouth >>

<< The tongue, which was found to be as soft as brain tissue and 10 times softer than a human's tongue, stretches and stores energy much like a spring >>

<< This combination of spit and softness is so effective that it provides the tongue 50 times greater work of adhesion than synthetic polymer materials such as sticky-hand toys >>

<< There are actually three phases (..) When the tongue first hits the insect, the saliva is almost like water and fills all the bug's crevices. Then, when the tongue snaps back, the saliva changes and becomes more viscous—thicker than honey, actually—gripping the insect for the ride back. The saliva turns watery again when the insect is sheared off inside the mouth >>

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:

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 ...' .

# behav: the self-medication poultice by orang-utans (Pongo pygmaeus)

<< Animals self-medicate using a variety of plant and arthropod secondary metabolites by either ingesting them or anointing them to their fur or skin apparently to repel ectoparasites and treat skin diseases >>

AA << document self-medication in the only Asian great ape, orang-utans (Pongo pygmaeus), and for the first time, to our knowledge, the external application of an anti-inflammatory agent in animals. The use of leaf extracts from Dracaena cantleyi by orang-utan has been observed on several occasions; rubbing a foamy mixture of saliva and leaf onto specific parts of the body. Interestingly, the local indigenous human population also use a poultice of these leaves for the relief of body pains >>
