Erika Hagelberg
Erika Hagelberg is a British Evolutionary geneticist and Professor of Biosciences at the University of Oslo. She works on ancient DNA and pioneered a means to extract DNA from bones. Her research has applications in evolutionary biology and forensic science. Education and early career At the age of 13, Hagelberg's father escaped from Nazi Germany to the United Kingdom on the Kindertransport in 1939. Hagelberg studied biochemistry at the University of London and earned her bachelor's degree in 1977. She moved to the University of Cambridge for her doctoral studies, earning her PhD in 1983. Traditionally, DNA could only be found in soft tissues, but Hagelberg developed techniques to recover small quantities of DNA from bone. Once the DNA has been extracted, it is possible to use the polymerase chain reaction to determine the sequence of nucleotides. Research Hagelberg works in the analysis of ancient DNA from archaeological bones. She joined the University of Oxford in 19 ...

University Of London
The University of London (UoL; abbreviated as Lond or more rarely Londin in post-nominals) is a federal public research university located in London, England, United Kingdom. The university was established by royal charter in 1836 as a degree-awarding examination board for students holding certificates from University College London and King's College London and "other such other Institutions, corporate or unincorporated, as shall be established for the purpose of Education, whether within the Metropolis or elsewhere within our United Kingdom". This fact allows it to be one of three institutions to claim the title of the third-oldest university in England, and moved to a federal structure in 1900. It is now incorporated by its fourth (1863) royal charter and governed by the University of London Act 2018. It was the first university in the United Kingdom to introduce examinations for women in 1869 and, a decade later, the first to admit women to degrees. In 1913, it appoi ...

University Of Oxford
The University of Oxford is a collegiate research university in Oxford, England. There is evidence of teaching as early as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled north-east to Cambridge where they established what became the University of Cambridge. The two English ancient universities share many common features and are jointly referred to as ''Oxbridge''. Both are ranked among the most prestigious universities in the world. The university is made up of thirty-nine semi-autonomous constituent colleges, five permanent private halls, and a range of academic departments which are organised into four divisions. All the colleges are self-governing institutions within the university, each controlling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Romanov Family
The House of Romanov (also transcribed Romanoff; rus, Романовы, Románovy, rɐˈmanəvɨ) was the reigning imperial house of Russia from 1613 to 1917. They achieved prominence after the Tsarina, Anastasia Romanova, was married to the First Tsar of Russia, Ivan the Terrible. The house became ''boyars'' (the highest rank in Russian nobility'')'' of the Grand Duchy of Moscow and later of the Tsardom of Russia under the reigning Rurik dynasty, which became extinct upon the death of Tsar Feodor I in 1598. The Time of Troubles, caused by the resulting succession crisis, saw several pretenders and imposters ( False Dmitris) fight for the crown during the Polish–Muscovite War of 1605–1618. On 21 February 1613, a ''Zemsky Sobor'' elected Michael Romanov as Tsar of Russia, establishing the Romanovs as Russia's second reigning dynasty. Michael's grandson Peter I, who established the Russian Empire in 1721, transformed the country into a great power through a series of war ...

He is mainly remembered for his actions at the Auschwitz II (Birkenau) concentration camp, where he performed deadly experiments on prisoners, was a member of the team of doctors who selected victims to be killed in the gas chambers, and was one of the doctors who administered the gas. With Red Army troops sweeping through German-occupied Poland, Mengele was transferred from Auschwitz to the Gross-Rosen concentration camp on 17 January 1945, ten days before the arrival of the Soviet forces at ...

DNA Extraction
The first isolation of deoxyribonucleic acid (DNA) was done in 1869 by Friedrich Miescher. Currently, it is a routine procedure in molecular biology or forensic analyses. For the chemical method, many different kits are used for extraction, and selecting the correct one will save time on kit optimization and extraction procedures. PCR sensitivity detection is considered to show the variation between the commercial kits. What does it deliver? DNA extraction is frequently a preliminary step in many diagnostic procedures used to identify environmental viruses and bacteria and diagnose illnesses and hereditary diseases. These methods consist of, but are not limited to: Fluorescence In Situ Hybridization (FISH) technique was developed in the 1980s. The basic idea is to use a nucleic acid probe to hybridize nuclear DNA from either interphase cells or metaphase chromosomes attached to a microscopic slide. It is a molecular method used, among other things, to recognize and count partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone
A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions. Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialized connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralization of bone; osteoclasts are involved in the resorption of bone tissue. Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mineralize ...

Mary Rose
The ''Mary Rose'' (launched 1511) is a carrack-type warship of the English Tudor navy of King Henry VIII. She served for 33 years in several wars against France, Scotland, and Brittany. After being substantially rebuilt in 1536, she saw her last action on 1545. She led the attack on the galleys of a French invasion fleet, but sank in the Solent, the strait north of the Isle of Wight. The wreck of the ''Mary Rose'' was located in 1971 and was raised on 11 October 1982 by the Mary Rose Trust in one of the most complex and expensive maritime salvage projects in history. The surviving section of the ship and thousands of recovered artefacts are of great value as a Tudor period time capsule. The excavation and raising of the ''Mary Rose'' was a milestone in the field of maritime archaeology, comparable in complexity and cost to the raising of the 17th-century Swedish warship '' Vasa'' in 1961. The ''Mary Rose'' site is designated under the Protection of Wrecks Act 1973 by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single Tandem Repeat
A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from one to six or more base pairs) are repeated, typically 5–50 times. Microsatellites occur at thousands of locations within an organism's genome. They have a higher mutation rate than other areas of DNA leading to high genetic diversity. Microsatellites are often referred to as short tandem repeats (STRs) by forensic geneticists and in genetic genealogy, or as simple sequence repeats (SSRs) by plant geneticists. Microsatellites and their longer cousins, the minisatellites, together are classified as VNTR (variable number of tandem repeats) DNA. The name "satellite" DNA refers to the early observation that centrifugation of genomic DNA in a test tube separates a prominent layer of bulk DNA from accompanying "satellite" layers of repetitive DNA. They are widely used for DNA profiling in cancer diagnosis, in kinship analysis (especially paternity testing) and in forensic identifica ...
