Color is in the eye of the beholder

The unique makeup of the cells in our retina, as well as the specific physical properties of substances themselves, explain why we occasionally see things change color before our very eyes! Samo and Marko Kreft from the University of Ljubljana in Slovenia investigated this phenomenon using pumpkin seed oil as an example. They have just published their research online in Springer's journal Naturwissenschaften.

1. The eyes have it: What do we see when we look at ads?
   08-07-2007 · EurekAlert!
   How do consumers look at advertisements? Most marketing textbooks advance the theory that looking at ads is a predominantly "dumb process," driven by visual stimuli such as the size of the ad or the color of the text. However, new research by researchers from the Netherlands and the University of Michigan uses eye-tracking software to reveal that it may be our goals -- the tasks we have in mind -- that drive what we pay attention to, even during a few seconds of ad exposure.

2. Blue eyes -- A clue to paternity
   10-23-2006 · EurekAlert!
   Before you request a paternity test, spend a few minutes looking at your child's eye color. According to studies, published this week in Behavioral Ecology and Sociobiology, the human eye color reflects a simple, predictable and reliable genetic pattern of inheritance. The researchers show that blue-eyed men find blue-eyed women most attractive. According to the researchers, it is because there could be an unconscious male adaptation for the detection of paternity, based on eye color.

3. The aye-ayes have it: The preservation of color vision in a creature of the night
   09-04-2007 · EurekAlert!
   Brian Verrelli and his ASU team have performed the first sweeping, genetic evolutionary study of color vision in the aye-aye (pronounced "eye-eye"), a bushy-tailed, Madagascar native primate. Verrelli, lead author George Perry, and collaborator Robert Martin's results, published in the journal Molecular Biology and Evolution, have led to some surprising conclusions on how this unusual nocturnal primate may have retained color vision function.

4. Blue-eyed humans have a single, common ancestor
   01-30-2008 · EurekAlert!
   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 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.

5. Is the beauty of a sculpture in the brain of the beholder?
   11-20-2007 · EurekAlert!
   Is there an objective biological basis for the experience of beauty in art? Or is aesthetic experience entirely subjective? This question has been addressed in a paper published in this week's PLoS ONE, Cinzia Di Dio, Emiliano Macaluso and Giacomo Rizzolatti. The researchers used fMRI scans to study the neural activity in subjects with no knowledge of art criticism, who were shown images of Classical and Renaissance sculptures.

6. Beyond nature vs. nurture: Williams syndrome across cultures
   01-24-2007 · EurekAlert!
   Nobody questions that the color of our eyes is encoded in our genes. When it comes to behavior the concept of "DNA as fate" quickly breaks down -- it's been long accepted that both genes and the environment shape human behavior. But just how much sway the environment holds over our genetic destiny has been difficult to untangle.

10. Researchers Uncover Critical Player In Cell Communication
    10-06-2006 · ScienceDaily
    Johns Hopkins researchers have teased out the function of a protein implicated in Williams-Beuren syndrome, a rare cognitive disorder associated with overly social behavior and lack of spatial awareness. Called TFII-I, or TF "two eye," the protein long known to help control a cell's genes also controls how much calcium a cell takes in, a function critical for all cells, including nerves in the brain. The study will be published this week in Science.
