Existem outros Bichos para além do Homem e do Covid-19

[Como existem outros doentes (agora abandonados e morrendo em segredo, em casa ou nos hospitais) para além dos originados por este novo coronavírus – “na moda, na média, na mediana, na bissetriz, etc.”, conforme o desejo dos “matemáticos” (os ditos “especialistas”) e o “interesse” (não tendo mais nada para dizer) da DGS.]

 

Tiny tardigrades might hold the key to the origin of life

“Tardigrades can come to a complete stop of metabolism with almost complete loss of water but can still restart life upon rehydration”. By removing all water, the animals can put life on hold. This form of “life pause” is called anhydrobiosis.

“We have no idea how life arose from matter several billion years ago.”

 

By studying tardigrade revival, we can get an idea of how molecules assemble in the spaces between cells in the tardigrade’s body. Before cells and life evolved, organic molecules had to put themselves together without the shelter provided by the cell, so what happens in tardigrades provides a good insight into that.

It seems that when the animals dry out and rehydrate, other bits of DNA can easily slip inside. Rather than cause a problem, tardigrades have embraced the benefits this can bring.
