New revolutionary sensor links pressure to color change
A high-resolution pressure sensor developed at the University of California, Riverside indicates pressure by varying its color -- a sensor that all of us can use with just our eyes. This sensor differs from commercially available pressure sensor films. The new technology produces a mosaic of easy-to-distinguish colors and has the benefit of higher contrast and resolution. It can potentially be used in many safety devices for revealing pressure distribution over even very complex surfaces. (2014-04-30)

Algae 'see' a wide range of light
Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. The study by researchers at UC Davis was published earlier this year in the journal Proceedings of the National Academy of Sciences. (2014-04-30)

Out of sight but not out of mind: Babies transfer learning from pictures to real objects by 9 months
A new study has found that by nine months babies can learn about an object from a picture of it. The study, which included about 30 British, predominately White eight to nine month olds, also found that babies can learn about an object from a black and white or color photo of that object. These findings have implications for parents and caregivers; before their first birthdays, children are learning about the real world from pictures. (2014-04-30)

People rely on what they hear to know what they're saying
You know what you're going to say before you say it, right? Not necessarily, research suggests. A study from researchers at Lund University in Sweden shows that auditory feedback plays an important role in helping us determine what we're saying as we speak. The study is published in Psychological Science, a journal of the Association for Psychological Science. (2014-04-29)

OCULLAR sees ocean color day and night
A team led at NASA's Goddard Space Flight Center in Greenbelt, Md., has developed an instrument capable of observing ocean color during normal sunlight conditions and under moonlight -- a first-ever capability that will allow scientists to monitor the health and chemistry of the planet's oceans literally around the clock.

Under some LED bulbs whites aren't 'whiter than white'
For years, companies have been adding whiteners to laundry detergent, paints, plastics, paper and fabrics to make whites look 'whiter than white,' but now, with a switch away from incandescent and fluorescent lighting, different degrees of whites may all look the same, according to experts in lighting.

Berkeley graduate student brings extinct plants to life
Most fossilized plants are fragments indistinguishable from a stick, but a UC Berkeley graduate student hopes a new technique will allow paleontologists to more precisely identify these fossils. Jeff Benca showed the power of this technique by turning a 375 million-year-old lycopod fossil into a life-like rendering that made the cover of the centennial issue of the American Journal of Botany.

Caucasian boys show highest prevalence of color blindness among preschoolers
The first major study of color blindness in a multi-ethnic group of preschoolers has uncovered that Caucasian male children have the highest prevalence among four major ethnicities, with one in 20 testing color blind. Researchers also found that color blindness, or color vision deficiency, in boys is lowest in African-Americans, and confirmed that girls have a much lower prevalence of color blindness than boys. The study will be published online Apr. 3 in Ophthalmology, the journal of the American Academy of Ophthalmology. (2014-04-03)

EEG study shows how brain infers structure, rules when learning
A new study documents the brain activity underlying our strong tendency to infer a structure of context and rules when learning new tasks (even when a structure isn't valid). The findings, which revealed individual differences, shows how we try to apply task knowledge to similar situations and could inform future research on learning disabilities. (2014-03-25)

Knowing whether food has spoiled without even opening the container (video)
A color-coded smart tag could tell consumers whether milk has turned sour or green beans have spoiled without opening the containers, say researchers. The tag, appearing on the packaging, also could be used to determine if medications and other perishable products were still active or fresh. The report was presented today at the 247th National Meeting & Exposition of the American Chemical Society. (2014-03-17)

Why soil changes color in air
Unusual phenomena of the change in the geotechnical characteristics of soil due to atmospheric oxidation are investigated on a micro-structure scale. Results obtained for the reformation of micro-structures in an atmospheric environment and its effects on soil properties provide theoretical support for the prediction and evaluation of the stability of the geotechnical environment. This study was published in Science China: Technological Sciences. (2014-03-06)

The nature of color: New formula to calculate hue improves accuracy of color analysis
Color is crucial in ecological studies, playing an important role in studies of flower and fruit development, responses to heat/drought stress, and plant-pollinator communication. But, measuring color variation is difficult, and available formulas sometimes give misleading results. An improved formula to calculate hue (one of three variables characterizing color), published in the March issue of Applications in Plant Sciences, corrects the popular segment classification method of color quantification and will provide accurate color analysis values. (2014-02-28)

Color of passion: Orange underbellies of female lizards signal fertility

Revision to rules for color in dinosaurs suggests connection between color and physiology
New research revising rules on deciphering color in dinosaurs may provide a tool for understanding the evolutionary emergence of flight and changes in dinosaur physiology. While surveying melanosome shape in fossil and extant specimens, a research team unexpectedly discovered that ancient maniraptoran dinosaurs, paravians, and living mammals and birds uniquely shared the evolutionary development of diverse melanosome shapes related to color. The similarity could relate to a key shift in dinosaurian physiology. (2014-02-12)

Computer models help decode cells that sense light without seeing
Researchers have found that the melanopsin pigment in the retina is potentially more sensitive to light than its more famous counterpart, rhodopsin, the pigment that allows for night vision. The staff of the Laboratory for Computational Photochemistry and Photobiology at Ohio's Bowling Green State University have leveraged OSC computing and storage systems to study melanopsin, a retina pigment capable of sensing environmental light changes, informing the nervous system and synchronizing it with the day/night rhythm. (2014-02-07)

Research on pigeon color reveals mutation hotspot
University of Texas at Arlington researchers worked in parallel with researchers at the University of Utah to examine three genes that control multiple color phenotypes, or appearances, in pigeons. The UT Arlington team found two independent deletions of regulatory sequences near the Sox10 gene produce (2014-02-06)

Birds of a different color
Scientists at the University of Utah identified mutations in three key genes that determine feather color in domestic rock pigeons. The same genes control pigmentation of human skin, and mutations in them can be responsible for melanoma and albinism. (2014-02-06)

Image or reality? Leaf research needs photos and lab analysis
Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be incomplete, according to new research. A new study shows that the peak in forest greenness as captured by digital pictures does not necessarily correspond to direct measures of peak chlorophyll content in leaves, which is an indicator of photosynthesis. The research has significant implications for how scientists use digital photos to study forest canopies. (2014-01-22)

A guppy's spots formed by layers of color cells
At least three pigment cell types from multiple layers of skin contribute to the color patterns of male guppies. (2014-01-22)
