Similarly, neither cellular nor viral individual genes or proteins are bythemselves alive. The enucleated cell is similar to the state of being brain dead, in that it lacks a full critical complexity. A virus, too, fails to reach a critical complexity. So life itself is anemergent, complex ...
observing how nature solved problems. A dirty stream, for example, often became clear after flowing through plants and along rocks where tiny creatures lived. When he got older, John started to wonder if this process could be...
Are viruses alive? This is a question scientists continue to discuss as definitions of life and ecology change. Current thinking suggests viruses should be considered part of a complex living system, one that extends between all organisms.
Virus Reproduction Obligate intercellular parasites Host range –Limited range of host cells each type of virus can infect –~ one cell type in multicellular organisms Host specificity –Recognition proteins “lock & key” 4 Virus Reproduction Recognition –Virus binds to host Entry –DNA only or en...
Although they have genes, they do not have cellular structure – which is the basic unit of life. To be considered alive, a form of life will use cell division to reproduce, whereas viruses spontaneously assemble within cells. The virus will be able to stay alive only by replicating...
The pandemic has not been kind to most of us, with all the enforced isolation and loneliness. I've been coping better than some, as my job is considered to be "essential services", and so I still haven't gotten to the point where I've emptied my Netflix queue yet. But as a longt...
The stereotype of what a middle-class man did with his money was perhaps nearer the truth. He was—and still is—inclined to take a longer-term view. Not only did he regard buying a house as a top priority, but he also considered the education of his children as extremely important. ...
The word has been used 459 times in the stories in 2020, with 287 of them as coronavirus, 168 as corona virus, and 4 as corona-virus. It is amazing that many of the themes young writers explored in fiction soon became a reality with the world in lockdown. Examples The nurses came ru...
Influenza viruses are presumed, but not conclusively known, to spread among humans by several possible routes. We provide evidence of a mode of transmission seldom considered for influenza: airborne virus transport on microscopic particles called “aerosolized fomites.” In the guinea pig model of inf...
the IIA showed it too was agile. Aharon recalled how the organization, working at 35% capacity because of the workplace restrictions put in place because of the virus, nonetheless managed to process the applications and respond to the companies within three to four weeks, expediting a process ...
