When viruses were measured, they were found to range in size from 16 millimicrons to 300 millimicrons. Most were found to be larger than the largest chemical molecules and smaller than the smallest living things.The answer to the puzzle - what is a virus - must be that it is both ...

Viruses exist wherever life is found. They are a major cause of mortality, a driver of global geochemical cycles and a reservoir of the greatest genetic diversity on Earth. In the oceans, viruses probably infect all living things, from bacteria to whales. They affect the form of available ...
which can cause extreme exhaustion — and postural orthostatic tachycardia syndrome — also known as POTS, which causes the heartbeat to speed up when standing up. Those are both illnesses that people can develop after other viruses, too. ...
remember his answer when I begged him to leave as soon as he could: “I’m not going to leave the city, I don’t want the children of Aleppo to feel so sad, I want to do something for them so that they smile and I want to help the poor civilians who are still living here.”...
On the other hand, certain retroviral gene products can have immunosuppressive properties. Exogenous viruses, such as HIV, use these mechanisms to suppress our own immune system. In the case of HERV, it seems that our own cells coopted these mechanisms for use in feto-maternal tolerance/immunos...
aA scientific research area devoted to the creation and study of computer simulations of living organisms. Computer viruses have forced a renewal of the debate on the definition of life. Besides forcing us to re-examine our definition of life, artificial life research may create more effective tec...
awhen the code of a virus is executed,it spreads itself to other programs。A typical computer virus does two things。first, it copies itself into previously uninfected programs。second,it executes other instructions that the virus creator has included in it。some viruses do not have any harmful...
Like many high school heads, Mike Warbel had a plan ready when the bad news came. It proved useful, yet (67) made him feel any better after two student lovers (68) suicide. A sadly high number of people of his same (69) face similar difficulties Ab
