Greenpeace is an independent global campaigning network, founded in Canada in 1971 by a group of environmental activists.Greenpeace states its goal is to "ensure the ability of the Earth to nurture life in all its diversity" [3] and focuses its campaigning on worldwide issues such as climate change, deforestation, overfishing, commercial whaling, genetic engineering, anti-war [4] and anti ...
Plaques from a virus isolated from a compost heap near UCLA. The bacterium is M. smegmatis. A viral plaque is a visible structure formed after introducing a viral sample to a cell culture grown on some nutrient medium. The virus will replicate and spread, generating regions of cell destruction known as plaques.
Virus crystallisation is the re-arrangement of viral components into solid crystal particles. [1] The crystals are composed of thousands of inactive forms of a particular virus arranged in the shape of a prism. [2] The inactive nature of virus crystals provide advantages for immunologists to effectively analyze the structure and function behind ...
While the terms "virus" and "virion" are occasionally confused, recently "virion" is used solely to describe the virus structure outside of cells, [3] while the terms "virus/viral" are broader and also include biological properties such as the infectivity of a virion. [4]
Greenpeace USA is a nonprofit 501(c) (4) lobby group that seeks “to change current environmental policies and practices” through “grassroots lobbying for various legislative initiatives.” The Greenpeace Fund is a 501 (c) (3) tax deductible charitable organization that promotes Greenpeace USA's mission to protect the environment.

Penaloza says that a biological advantage viruses and bacteria have over fungi is that they replicate much faster — enabling them to spread more easily. “It depends on the virus, of course ...
Bacteria resist phage infection through restriction modification systems that degrade foreign DNA [144] and a system that uses CRISPR sequences to retain fragments of the genomes of phage that the bacteria have come into contact with in the past, which allows them to block virus replication through a form of RNA interference.
The virus then assembles, and the bacterial cell lyses, releasing new viruses. The virus was isolated in 1961 and its genome was the first to be fully sequenced, in 1976, providing a crucial understanding of genetic codes. In practical applications, MS2's structural components have been used to detect RNA in living cells.
