Adriana Briscoe
Adriana Darielle Mejía Briscoe is an American evolutionary biology, evolutionary biologist and Professor of Ecology and Evolutionary Biology at the School of Biological Sciences at the University of California, Irvine. She specializes in research questions at the intersection of sensory physiology, color vision, coloration, animal behavior, molecular evolution, and genomics. Briscoe's work is largely focused on questions surrounding vision in butterfly, butterflies with a specific focus on establishing links between genetic expression patterns leading to coloration and vision with the physiological and behavioral traits of butterflies. Briscoe has discovered and systematically demonstrated over the course of her career that butterflies are a unique organism to enable such studies on account of the diversity of photoreceptor proteins, or opsins, which are expressed in the retina of a butterfly. She is also known for her studies on gene expression of phototransduction proteins, dup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaii
Hawaii ( ; haw, Hawaii or ) is a state in the Western United States, located in the Pacific Ocean about from the U.S. mainland. It is the only U.S. state outside North America, the only state that is an archipelago, and the only state geographically located within the tropics. Hawaii comprises nearly the entire Hawaiian archipelago, 137 volcanic islands spanning that are physiographically and ethnologically part of the Polynesian subregion of Oceania. The state's ocean coastline is consequently the fourth-longest in the U.S., at about . The eight main islands, from northwest to southeast, are Niihau, Kauai, Oahu, Molokai, Lānai, Kahoolawe, Maui, and Hawaii—the last of these, after which the state is named, is often called the "Big Island" or "Hawaii Island" to avoid confusion with the state or archipelago. The uninhabited Northwestern Hawaiian Islands make up most of the Papahānaumokuākea Marine National Monument, the United States' largest protected ...

Guggenheim Fellowship
Guggenheim Fellowships are grants that have been awarded annually since by the John Simon Guggenheim Memorial Foundation to those "who have demonstrated exceptional capacity for productive scholarship or exceptional creative ability in the arts." Each year, the foundation issues awards in each of two separate competitions: * One open to citizens and permanent residents of the United States and Canada. * The other to citizens and permanent residents of Latin America and the Caribbean. The Latin America and Caribbean competition is currently suspended "while we examine the workings and efficacy of the program. The U.S. and Canadian competition is unaffected by this suspension." The performing arts are excluded, although composers, film directors, and choreographers are eligible. The fellowships are not open to students, only to "advanced professionals in mid-career" such as published authors. The fellows may spend the money as they see fit, as the purpose is to give fellows "b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retinitis Pigmentosa
Retinitis pigmentosa (RP) is a genetic disorder of the eyes that causes loss of vision. Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). As peripheral vision worsens, people may experience "tunnel vision". Complete blindness is uncommon. Onset of symptoms is generally gradual and often begins in childhood. Retinitis pigmentosa is generally inherited from one or both parents or rarely it can be caused by a miscoding during DNA division. It is caused by genetic miscoding of proteins in one of more than 300 genes involved. The underlying mechanism involves the progressive loss of rod photoreceptor cells that line the retina of the eyeball. The rod cells secrete a neuroprotective substance (Rod-derived cone viability factor, RdCVF) that protects the cone cells from apoptosis (cell death). However, when the rod cells die, this substance is no longer provided. This is generally followed by the loss of cone photorecept ...

Gene Duplication
Gene duplication (or chromosomal duplication or gene amplification) is a major mechanism through which new genetic material is generated during molecular evolution. It can be defined as any duplication of a region of DNA that contains a gene. Gene duplications can arise as products of several types of errors in DNA replication and repair machinery as well as through fortuitous capture by selfish genetic elements. Common sources of gene duplications include ectopic recombination, retrotransposition event, aneuploidy, polyploidy, and replication slippage. Mechanisms of duplication Ectopic recombination Duplications arise from an event termed unequal crossing-over that occurs during meiosis between misaligned homologous chromosomes. The chance of it happening is a function of the degree of sharing of repetitive elements between two chromosomes. The products of this recombination are a duplication at the site of the exchange and a reciprocal deletion. Ectopic recombination is ...

Photoreceptor Protein
Photoreceptor proteins are light-sensitive proteins involved in the sensing and response to light in a variety of organisms. Some examples are rhodopsin in the photoreceptor cells of the vertebrate retina, phytochrome in plants, and bacteriorhodopsin and bacteriophytochromes in some bacteria. They mediate light responses as varied as visual perception, phototropism and phototaxis, as well as responses to light-dark cycles such as circadian rhythm and other photoperiodisms including control of flowering times in plants and mating seasons in animals. Structure Photoreceptor proteins typically consist of a protein attached to a non-protein chromophore (sometimes referred as photopigment, even so photopigment may also refer to the photoreceptor as a whole). The chromophore reacts to light via photoisomerization or photoreduction, thus initiating a change of the receptor protein which triggers a signal transduction cascade. Chromophores found in photoreceptors include retinal (reti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Evolution
Molecular evolution is the process of change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes. Major topics in molecular evolution concern the rates and impacts of single nucleotide changes, neutral evolution vs. natural selection, origins of new genes, the genetic nature of complex traits, the genetic basis of speciation, evolution of development, and ways that evolutionary forces influence genomic and phenotypic changes. History The history of molecular evolution starts in the early 20th century with comparative biochemistry, and the use of "fingerprinting" methods such as immune assays, gel electrophoresis and paper chromatography in the 1950s to explore homologous proteins. The field of molecular evolution came into its own in the 1960s and 1970s, following the rise of molecular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ford Foundation
The Ford Foundation is an American private foundation with the stated goal of advancing human welfare. Created in 1936 by Edsel Ford and his father Henry Ford, it was originally funded by a US$25,000 gift from Edsel Ford. By 1947, after the death of the two founders, the foundation owned 90% of the non-voting shares of the Ford Motor Company. (The Ford family retained the voting shares.) Between 1955 and 1974, the foundation sold its Ford Motor Company holdings and now plays no role in the automobile company. Ahead of the foundation selling its Ford Motor Company holdings, in 1949, Henry Ford II created the , a separate corporate foundation that to this day serves as the philanthropic arm of the Ford Motor Company and is not associated with the foundation. The Ford Foundation makes grants through its headquarters and ten international field offices. For many years, the foundation's financial endowment was the largest private endowment in the world; it remains among the wealthie ...

University Of Colorado Denver
The University of Colorado Denver (CU Denver) is a Public university, public research university in Denver, Colorado. It is part of the University of Colorado system. History University of Colorado System Anschutz Medical Campus The University of Colorado created the Department of Medicine and Surgery in September 1883 in the Old Main building on the CU Boulder, Boulder campus. The Department of Nursing opened in 1898. By 1892, the last two years of classes were taught in Denver because the larger population afforded more practical experience. This practice triggered something of a turf battle with the University of Denver's medical school and the subsequent legal battle went to the Supreme Court of Colorado, state Supreme Court. In 1897, the court found that CU's charter restricted them to Boulder, Colorado, Boulder. However, in 1910, University of Colorado system, CU got an amendment to the Law and Government of Colorado, state Constitution passed which allowed them to move b ...
