Research Institutes In The United States
Research is creative and systematic work undertaken to increase the stock of knowledge. It involves the collection, organization, and analysis of evidence to increase understanding of a topic, characterized by a particular attentiveness to controlling sources of bias and error. These activities are characterized by accounting and controlling for biases. A research project may be an expansion of past work in the field. To test the validity of instruments, procedures, or experiments, research may replicate elements of prior projects or the project as a whole. The primary purposes of basic research (as opposed to applied research) are documentation, discovery, interpretation, and the research and development (R&D) of methods and systems for the advancement of human knowledge. Approaches to research depend on epistemologies, which vary considerably both within and between humanities and sciences. There are several forms of research: scientific, humanities, artistic, economic, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetics Or Genomics Research Institutions
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the con ...

New York Times Magazine
''The New York Times Magazine'' is an American Sunday magazine included with the Sunday edition of ''The New York Times''. It features articles longer than those typically in the newspaper and has attracted many notable contributors. The magazine is noted for its photography, especially relating to fashion and style. History 19th century Its first issue was published on September 6, 1896, and contained the first photographs ever printed in the newspaper.The New York Times CompanyNew York Times Timeline 1881-1910. Retrieved on 2009-03-13. In the early decades, it was a section of the broadsheet paper and not an insert as it is today. The creation of a "serious" Sunday magazine was part of a massive overhaul of the newspaper instigated that year by its new owner, Adolph Ochs, who also banned fiction, comic strips, and gossip columns from the paper, and is generally credited with saving ''The New York Times'' from financial ruin.

Indo-European Languages
The Indo-European languages are a language family native to the northern Indian subcontinent, most of Europe, and the Iranian plateau with additional native branches found in regions such as Sri Lanka, the Maldives, parts of Central Asia (e.g., Tajikistan and Afghanistan), Armenia, and areas of southern India. Historically, Indo-European languages were also spoken in Anatolia. Some European languages of this family—English language, English, French language, French, Portuguese language, Portuguese, Russian language, Russian, Spanish language, Spanish, and Dutch language, Dutch—have expanded through colonialism in the modern period and are now spoken across several continents. The Indo-European family is divided into several branches or sub-families, including Albanian language, Albanian, Armenian language, Armenian, Balto-Slavic, Celtic languages, Celtic, Germanic languages, Germanic, Hellenic languages, Hellenic, Indo-Iranian languages, Indo-Iranian, and Italic languages, ...

Indo-European Migrations
The Indo-European migrations are hypothesized migrations of Proto-Indo-Europeans, peoples who spoke Proto-Indo-European language, Proto-Indo-European (PIE) and the derived Indo-European languages, which took place from around 4000 to 1000 BCE, potentially explaining how these related languages came to be spoken across a large area of Eurasia spanning from the Indian subcontinent and Iranian plateau to Atlantic Europe, in a process of cultural diffusion. While these early languages and their speakers are Prehistory, prehistoric (lacking documentary evidence), a synthesis of linguistics, archaeology, anthropology and genetics has established the existence of Proto-Indo-European and the spread of its daughter dialects through migrations of large populations of its speakers, as well as the recruitment of new speakers through emulation of conquering elites. Comparative linguistics describes the similarities between various languages governed by laws of systematic Language change, ch ...

Genetic History Of The Indigenous Peoples Of The Americas
The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), and European contact, after about 500 years ago. The first period of the genetic history of Indigenous Americans is the determinant factor for the number of genetic lineages, zygosity mutations, and founding haplotypes present in today's Indigenous American populations. Indigenous American populations descend from and share ancestry with an Ancient East Asian lineage which diverged from other East Asian peoples prior to the Last Glacial Maximum (26–18 kya). They also received geneflow from Ancient North Eurasians, a distinct Paleolithic Siberian population with deep affinities to both "European hunter-gatherers" (e.g. Kostenki-14) and "Basal East Asians" (e.g. Tianyuan man). They later dispersed throughout the Americas after about 16,000 years ago (exceptions being the Na-Dene and Es ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eurasia
Eurasia ( , ) is a continental area on Earth, comprising all of Europe and Asia. According to some geographers, Physical geography, physiographically, Eurasia is a single supercontinent. The concept of Europe and Asia as distinct continents dates back to classical antiquity, antiquity, but their borders have historically been subject to change. For example, the ancient Greeks originally included Africa in Asia but classified Europe as separate land. Eurasia is connected to Africa at the Suez Canal, and the two are sometimes combined to describe the largest contiguous landmass on Earth, Afro-Eurasia. History Eurasia has been the host of many ancient civilizations, including those based in Mesopotamia, Egypt, the Indus Valley and China. In the Axial Age (mid-first millennium BCE), a continuous belt of civilizations stretched through the Eurasian Subtropics, subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetics And Archaeogenetics Of South Asia
Genetics and archaeogenetics of South Asia is the study of the genetics and archaeogenetics of the ethnic groups of South Asia. It aims at uncovering these groups' genetic histories. The geographic position of the Indian subcontinent makes its biodiversity important for the study of the early dispersal of anatomically modern humans across Asia. Based on mitochondrial DNA (mtDNA) variations, genetic unity across various South Asian subpopulations have shown that most of the ancestral nodes of the phylogenetic tree of all the mtDNA types originated in the subcontinent. Conclusions of studies based on Y chromosome variation and autosomal DNA variation have been varied. The genetic makeup of modern South Asians can be described at the deepest level as a combination of West Eurasian (related to ancient and modern people in Europe and West Asia) ancestries with divergent East Eurasian ancestries. The latter primarily include a proposed indigenous South Asian component (termed ''Anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
