Trust Me! I Have Brown Eyes And The Face To Go With Them

redOrbit Staff & Wire Reports - Your Universe Online Ever wonder what makes you feel that instinctive sense of trust — or mistrust — when you meet someone new? In a new study published this week in the online journal PLoS ONE, researchers at Charles University in the Czech Republic explored this question by asking 238 participants to look at the faces of 80 students and rate their trustworthiness, attractiveness and dominance. As expected, the team found that all three...

Lawrence LeBlond for redOrbit.com - Your Universe Online The next time you leave your DNA behind be forewarned that you are now not only leaving your biological fingerprint behind for prying eyes, but also leaving evidence of what color your hair and eyes are. Until the mid-1980s, DNA at a crime scene went largely unchecked due to lack of technology to search it out. And for the last two decades, in order for a crime scene detective to match DNA to a suspect, samples had to be taken from...

University of Colorado School of Medicine leads multi-center study Eye color may be an indicator of whether a person is high-risk for certain serious skin conditions. A study, led by the University of Colorado School of Medicine, shows people with blue eyes are less likely to have vitiligo. It then follows, according to scientists, that people with brown eyes may be less likely to have melanoma. Vitiligo is an autoimmune skin disease in which pigment loss results in irregular white patches...

Controversial Treatment Makes Brown Eyes Blue

A California scientist claims he has developed a simple procedure that can turn brown eyes into blue eyes, but once the procedure is done it is irreversible, CBS News reports. Dr Gregg Homer, of Stroma Medical in California said his new Lumineyes technology uses a laser tuned to a specific frequency to permanently turn brown eyes blue, by removing the brown pigment, or melanin, from the top layer of the iris, leaving the blue eye color to emerge over the course of a few weeks. Homer...

Beauty is said to be in the eye of the beholder, but a new study reveals that the reverse is also true; unattractiveness is in the eye of the beheld. Research published in Ethology finds that people with bloodshot eyes are considered sadder, unhealthier and less attractive than people whose eye whites are untinted, a cue which is uniquely human."Red, 'bloodshot' eyes are prominent in medical diagnoses and in folk culture", said lead author Dr. Robert R. Provine from the University of...

Three new genetic loci have been identified with involvement in subtle and quantitative variation of human eye color. The study, led by Manfred Kayser of the Erasmus University Medical Center Rotterdam, The Netherlands, was published May 6 in the open-access journal PLoS Genetics. Previous studies on the genetics of human eye color used broadly-categorized trait information such as 'blue', 'green', and 'brown'; however, variation in eye color exists in a continuous grading from the lightest...

People preferentially marry those with similar ancestry, but their decisions are not necessarily based on hair, eye or skin color. Research, published in BioMed Central's open access journal Genome Biology, shows that Mexicans mate according to proportions of Native American to European ancestry, while Puerto Ricans are more likely to settle down with someone carrying a similar mix of African and European genes. Neil Risch, from the University of California, San Francisco, worked with a team...

More and more information is being gathered about how human genes influence medically relevant traits, such as the propensity to develop a certain disease. The ultimate goal is to predict whether or not a given trait will develop later in life from the genome sequence alone (i.e. from the sequence of the bases that make up the DNA strands that store genetic information in every cell of the body). Now, writing in the journal Current Biology, a Cell Press publication, a group of researchers...

By Hu, Dan-Ning Simon, John D; Sarna, Tadeusz ABSTRACT The mammalian eye consists of several layers of pigmented tissues that contain melanin. The eye is a unique organ for pigment cell research because one can isolate and compare melanosomes from different tissues and embryonic origins. Retinal, iris and ciliary pigment epithelial cells are derived from the neural ectoderm, more specifically from the extremity of the embryonic optical cup, which is also the origin of the retina. In...

New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today. What is the genetic mutation "Originally, we all had brown eyes", said Professor Eiberg from the Department of Cellular and Molecular Medicine. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted...
