Pathogenic Microorganisms In Frozen Environments
On Earth, frozen environments such as permafrost and glaciers are known for their ability to preserve items, as they are too cold for ordinary decomposition to take place. This makes them a valuable source of archeological artefacts and prehistoric fossils, yet it also means that there are certain risks once ancient organic matter is finally subject to thaw. The best-studied risk is that of decomposition of such organic matter releasing a substantial quantity of carbon dioxide and methane, and thus acting as a notable climate change feedback. Yet, some scientists have also raised concerns about the possibility that some Dormancy#Bacteria, metabolically dormant bacteria and protists, as well as always metabolically inactive viruses, may both survive the thaw and either threaten humans directly, or affect some of the animal or plant species important for human wellbeing. As of 2023, there has been at least one recorded reemergence of anthrax, a pathogen long-known for its ability to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

1918 Influenza Virus
The 1918–1920 flu pandemic, also known as the Great Influenza epidemic or by the common misnomer Spanish flu, was an exceptionally deadly global influenza pandemic caused by the H1N1 subtype of the influenza A virus. The earliest documented case was March 1918 in Kansas, United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it the deadliest pandemic in history. The pandemic broke out near the end of World War I, when wartime censors in the belligerent countries suppressed bad news to maintain morale, but newspapers freely reported the outbreak in neutral Spain, creating a false impression of Spain as the epicenter and leading to the "Spanish flu" misnomer. Limited historical epidemiological data make the pandemic's geog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
