Ultrasound first, not CT, for diagnosing suspected acute appendicitis
Color Doppler ultrasound, not CT, should be the first imaging examination for adult patients with suspected acute appendicitis, a new study emphasizes.   view more (2008-05-08)

Scientists find color vision system independent of motion detection
The vision system used to process color is separate from that used to detect motion, according to a new study by researchers at New York University's Center for Developmental Genetics and in the Department of Genetics and Neurobiology at Germany's University of Würzburg.   view more (2008-03-20)

How carrots help us see the color orange
One of the easiest ways to identify an object is by its color -- perhaps it is because children's books encourage us to pair certain objects with their respective colors. Why else would so many of us automatically assume carrots are orange, grass is green and apples are red?   view more (2008-07-23)

More than meets the tongue
Does orange juice taste sweeter if it's a brighter orange? A new study in the March issue of the Journal of Consumer Research finds that the color of a drink can influence how we think it tastes.   view more (2007-02-13)

Behavioral studies show UV contributes to marsupial color vision
Work reported this week provides new evidence that marsupials, like primates, have functional color vision based on three different types of color photoreceptor cones-but unlike primates, a component of marsupial color vision includes sensitivity to ultraviolet wavelengths.   view more (2006-03-21)

Seeing colors -- New study sheds light on sensory system quirk
In the psychological phenomenon known as "synesthesia," individuals' sensory systems are a bit more intertwined than usual. Some people, for example, report seeing colors when musical notes are played.   view more (2007-07-25)

Blue eyes - a clue to paternity
Before you request a paternity test, spend a few minutes looking at your child's eye color.   view more (2006-10-24)

NEW DIAGNOSTIC METHOD COULD IMPROVE DETECTION OF PROSTATE CANCER (p 1849)
A new diagnostic technique using colour Doppler with an ultrasound contrast agent is more effective than conventional systematic biopsy in diagnosing prostate cancer, conclude the authors of a research letter in this week's issue of THE LANCET. Prostate cancer detection is currently based on three... view more (2001-06-06)

The more common the digit, the more radiant the color in grapheme color synaesthesia
A psychological phenomenon known as "grapheme-color synaesthesia" describes individuals who experience vivid colors whenever they see, hear, or think of ordinary letters and digits.   view more (2007-09-19)

Giant Pandas See in Color
They may be black and white, but new research at the Georgia Institute of Technology and Zoo Atlanta shows that giant pandas can see in color.   view more (2006-10-16)

Research on the color red shows definite impact on achievement
The color red can affect how people function: Red means danger and commands us to stop in traffic. Researchers at the University of Rochester have now found that red also can keep us from performing our best on tests.   view more (2007-03-01)

New procedure safer for detecting fetal anemia
An innovative, non invasive ultrasound procedure to detect anemia in the fetus during high risk pregnancy is safer for patients.   view more (2006-07-13)

Which came first: Primates' ability to see colorful food or see colorful sex?
The adaptive significance of the unique ability in many primates to distinguish red hues from green ones (i.e., trichromatic color vision) has always enticed debate among evolutionary biologists.   view more (2007-06-27)

A blue ring around the planet Uranus
The outermost ring of the planet Uranus turns out to have a bright blue color, according to a report in the April 7 issue of the journal Science.   view more (2006-04-07)

Colorful bacteria more dangerous
A new study in the July 18 issue of The Journal of Experimental Medicine shows that gold-colored bacteria are more harmful than their unpigmented relatives. A group of scientists led by Victor Nizet (UCSD, San Diego, CA) have discovered that the molecules that give certain bugs their color also... view more (2005-07-12)

Earth light: Terrestrial vegetation detected in the spectrum of the earthshine
A team including Pierre Riaud and Jean Schneider of the Observatoire de Paris and Luc Arnold, Sophie Gillet and Olivier Lardie're of the Observatoire de Haute Provence detected for the first time the color characteristic of the terrestrial vegetation in the "Earthshine", i.e. the dark part of the... view more (2002-01-23)

NYU scientists set stage for understanding how color vision is processed
New York University biologists have mapped the medulla circuitry in fruit flies, setting the stage for subsequent research on how color vision is processed.   view more (2008-03-26)

NASA'S Cassini spacecraft captures Saturnian moon ballet
The cold, icy orbs of the Saturn system come to life in a slew of new movie clips showing the ringed planet's moons in motion.   view more (2006-06-22)

Multiple genes permit closely related fish species to mix and match their color vision
Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using... view more (2005-10-11)

New Research Shows Consistency in Synaesthetic Experiences
A quirky psychological phenomenon known as "grapheme-color synaesthesia" describes individuals who experience vivid colors whenever they see, hear, or think of ordinary letters and digits.   view more (2008-04-30)

Color Vision Drove Primates to Develop Red Skin and Hair, Study Finds
You might call it a tale of "monkey see, monkey do." Researchers at Ohio University have found that after primates evolved the ability to see red, they began to develop red and orange skin and hair.   view more (2007-05-25)

New technology may help Olympic sailing
A team of researchers at the Ocean University of China has developed and tested a mobile lidar (light detection and ranging) station that can accurately measure wind speed and direction over large areas in real time -- an application useful for aviation safety, weather forecasting and sports.   view more (2008-07-01)

New developments in assessing fluid flows
Scientists at Oxford University are developing a new Doppler Global Velocimetry (DGV) technique that will enable three-dimensional fluid velocity fields to be imaged reliably and accurately. Over the last twenty years, a number of techniques have been explored to enable clear imaging of fluid... view more (2002-07-03)

The aye-ayes have it: The preservation of color vision in a creature of the night
A quest to gain a more complete picture of color vision evolution has led Biodesign Institute researcher Brian Verrelli to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates.   view more (2007-09-05)

MIT gel changes color on demand
MIT researchers have created a new structured gel that can rapidly change color in response to a variety of stimuli, including temperature, pressure, salt concentration and humidity.   view more (2007-10-22)
