Stanford University Medical Center The first large-scale, comprehensive analysis of the genomic diversity of Mexico — led by researchers at the Stanford University School of Medicine, the University of California-San Francisco and the Mexican National Institute of Genomic Medicine — has identified a dazzling mosaic of genotypes and population substructures across the country. Some groups are as genetically different from one another as Europeans are from East Asians. The study,...

April Flowers for redOrbit.com - Your Universe Online There is an old saying that one should never judge a book by its cover, and that seems to be true for turtles as well. This diamondback terrapin is known for the diverse patterns intricately grooved into its shell. The pattern makes the turtle instantly recognizable, however it does not solve the problem of conservation for these coastal animals. That answer, according to a new study from the United States Geological Survey (USGS), is...

Tiger Conservation Efforts Should Focus On Genetic Diversity
2014-04-17 04:27:58

Brett Smith for redOrbit.com - Your Universe Online While many tiger conservation efforts focus on the numbers of a population, maintaining the big cats’ genetic diversity is just as important, according to a report published on Thursday in the Journal of Heredity. "Numbers don't tell the entire story," study author Elizabeth Hadly, a professor in environmental biology at Stanford University, said in a recent statement. According to the study, because the tiger’s decline has...

Study Finds Recent Wolf-dog Hybridization In Caucasus Region
2014-04-14 15:50:55

American Genetic Association Dog owners in the Caucasus Mountains of Georgia might want to consider penning up their dogs more often: hybridization of wolves with shepherd dogs might be more common, and more recent, than previously thought, according to a recently published study in the Journal of Heredity (DOI: 10.1093/jhered/esu014). Dr. Natia Kopaliani, Dr. David Tarkhnishvili, and colleagues from the Institute of Ecology at Ilia State University in Georgia and from the Tbilisi Zoo...

Physicists play with the genetics of populations What happens when physicists play (using mathematical instruments) with the genetics of populations? They may discover unexpected connections between migration and biodiversity, for example, as recently done by a group of researchers from the International School for Advanced Studies (SISSA) in Trieste and the Polytechnic University in Turin in a study published in the journal Physical Review Letters. The effect of migration on...

Scientists Identify Factors Limiting Hybridization Of Closely-related Woodrat Species
2014-03-31 08:41:24

Wildlife Conservation Society A pair of new studies from the Wildlife Conservation Society, Idaho State University, and the University of Nevada Reno look at the surprising variety of factors that prevent two closely related species of woodrats from becoming a single hybrid species despite the existence of hybrid individuals where the two species come into contact. After finding that two closely related species, the desert and Bryant's woodrats, could interbreed and produce hybrid...

Cocaine And Methamphetamine Response Differ Between Two Substrains Of 'Black 6' Laboratory Mouse
2013-12-20 06:45:36

Jackson Laboratory Researchers including Jackson Laboratory Professor Gary Churchill, Ph.D., have found a single nucleotide polymorphism (SNP) difference in cocaine and methamphetamine response between two substrains of the C57BL/6 or "Black 6" inbred laboratory mouse, pointing to Cyfip2 as a regulator of cocaine response with a possible role in addiction. The research team, led by Joseph Takahashi, Ph.D., of University of Texas Southwestern Medical Center and the Howard Hughes Medical...

Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or...

Historical records are often used to learn about ancestry but a new approach, using genetics, is currently being applied. In a recent study, published in PLOS Genetics, scientists from the Stanford University School of Medicine and the University of Miami Miller School of Medicine compared patterns of genetic variation found in populations in and around the Caribbean. They were able to discern an influx of European genes into the native population that occurred within a generation of...

House Mouse, Mus musculus
2012-05-01 11:42:07

Even in the wild, this rodent is associated with humans by destroying crops and stored food. The house mouse is also known as the fancy mouse, a common pet. It is also a widely used laboratory animal, important for testing in genetics, biology, and medicine. There are three recognized subspecies of the house mouse. These mice thrive in a number of locations including fields, houses, and commercial structures. An adult male house mouse can have a body length of up to 3.9 in, and tail length...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
