Pandoravirus
''Pandoravirus'' is a proposed genus of giant virus, first discovered in 2013. It is the third largest in physical size of any known viral genus, behind Pithovirus and Megaklothovirus. Pandoraviruses have double stranded DNA genomes, with the largest genome size (2.5 million base pairs) of any known viral genus. Discovery The discovery of Pandoraviruses by a team of French scientists, led by husband and wife Jean-Michel Claverie and Chantal Abergel, was announced in a report in the journal ''Science'' in July 2013. Other scientists had previously observed the pandoravirus particles, but owing to their enormous size they were not expected to be viruses. Patrick Scheid, a parasitologist from the Central Institute of the Bundeswehr Medical Service in Koblenz, Germany, found one in 2008, in an amoeba living in the contact lens of a woman with keratitis. Its development within the amoebal host was documented extensively. Unlike in other cases with such giant viruses, the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Pampulha
__NOTOC__ Lake Pampulha ( Portuguese: Lagoa da Pampulha, ) is an artificial lake located in Pampulha, Belo Horizonte, in the Brazilian state of Minas Gerais. Pampulha is also the name of an administrative region (''região administrativa'') of Belo Horizonte, and the name of one of 29 neighborhoods (''bairros'') within the administrative region of the same name. The lake was built in the early 1940s during the mayoralty of Juscelino Kubitschek, later president of Brazil from 1956 to 1961. Pampulha was created as a source of drinking water for the city of Belo Horizonte, but quickly became polluted. Lake Pampulha covers , has a volume of , and a drainage basin of . It has a mean depth of and reaches a maximum depth of . The lake is fed by 8 small streams, the largest being the Sarandi and Ressaca. 424,000 residents live in the catchment area of the lake. Landmarks Many of Belo Horizonte's cultural landmarks are located around or close to the lake, including the Federal Univers ...

DNA Viruses
A DNA virus is a virus that has a genome made of deoxyribonucleic acid (DNA) that is replicated by a DNA polymerase. They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses. dsDNA viruses primarily belong to two realms: ''Duplodnaviria'' and ''Varidnaviria'', and ssDNA viruses are almost exclusively assigned to the realm ''Monodnaviria'', which also includes some dsDNA viruses. Additionally, many DNA viruses are unassigned to higher taxa. Reverse transcribing viruses, which have a DNA genome that is replicated through an RNA intermediate by a reverse transcriptase, are classified into the kingdom '' Pararnavirae'' in the realm ''Riboviria''. DNA viruses are ubiquitous worldwide, especially in marine environments where they form an important part of marine ecosystems, and infect both prokaryotes and eukaryotes. They a ...
