# gst: apropos how to manage misfolding (proteins)

<< Proteins are made up of chains of amino acids and during their formation they must fold to acquire an appropriate shape enabling them to perform their functions. However, when cells are subjected to stress or harm, such as high temperatures, some of the proteins may not fold properly. >>

<< There are three ways to solve the problem. The first option is to try to fix the folding in order to regain function, but this can be tricky because if stress conditions continue, the proteins continue unfolding. A second way is to destroy proteins that have not properly folded by way of machinery called proteasomes. But, in this study we reveal that the dominant route in yeast is a third option consisting of the formation of aggregates to protect misfolded proteins from degradation, >> Elena Hidalgo.

# gst: monkeyflower Mimulus code, with a simple spot generator inside

<< Many organisms exhibit visually striking spotted or striped pigmentation patterns. Developmental models predict that such spatial patterns can form when a local autocatalytic feedback loop and a long-range inhibitory feedback loop interact. At its simplest, this self-organizing network only requires one self-activating activator that also activates a repressor, which inhibits the activator and diffuses to neighboring cells. >>

<< Patterns are everywhere in nature, not just color patterns but even how leaves are arranged on a stem, really anything with periodicity. Explaining these patterns could be similar in principle and that is what we're hoping to do, >> Yaowu Yuan

# life: a funky, immediate approach of the sneezing from Wuhan (a relative safe barrier - this device is NOT a filter)

if (of course, if and only if) the problem is to save Western civilization from autocatalytic noise (and subsequent psychic, behavioral, political, economical, cultural catapulting collapse) caused by 1,2 sneezing of Wuhan, here a funky, immediate approach;

you have to get it: 

(1) thiny film (e.g. one piece of a thin film roll, made by polyethylene, used to wrap food);

(2) pocket cotton handkerchief  (like the ones used by cowboys, like those popping out of the pocket of the jackets that italian Prime Minister wears, perhaps wider);

(3) scotch tape (transparent adhesive tape);

below the assembly (1-3 minutes to compose it, two or 'n' times a day); 

This device is relatively safe even if your interlocutor spits in your mouth (in that  case, to protect the eyes you remember that you also need protective glasses and any earplugs, disposable gloves ...);

you can get more security by spraying - on the outside of the handkerchief - a mixture of alcohol, hydrogen peroxide (H2O2) and distilled water (the composition indicated by the WHO,  without glycerol);  cfr Guide to Local Production:  WHO-recommended Handrub Formulations  (reagents for formulation 1) Revised April 2010

https://www.who.int/gpsc/5may/Guide_to_Local_Production.pdf

With this device you can travel around the city, on buses, on trains, ... in relative safety, yours and your neighbors; 

instead of film roll for food you could use a waterproofing spray but the cost is high and the chemical one is probably toxic for human

# gst: apropos of 'reprogrammed by a virus' (2), the case of 'virocells'

<< If it looks like a duck and quacks like a duck, so the adage goes, it must be a duck. But if the duck gets infected by a virus so that it no longer looks or quacks like one, is it still a duck? >>

<< Ocean viruses are abundant and infect 20–40% of surface microbes. Infected cells, termed virocells, are thus a predominant microbial state. Yet, virocells and their ecosystem impacts are understudied, thus precluding their incorporation into ecosystem models. >>

<< Ecologically, this work suggests that one cell, infected versus uninfected, can have immensely different metabolisms that affect the ecosystem differently. >>
