Could Your Eye Color Predict Your Drinking Habits?
Research from the University of Vermont suggests that people with lighter colored eyes may be at a higher risk for alcoholism. The study examined a group of 1,263 European-American patients, including 992 people with alcohol dependency problems and 271 without alcohol problems.
Among the sample, those with light-colored eyes (blue, green, gray and light brown) had a 54 percent higher rate of alcohol dependence than that of people with dark-brown eyes. Those with blue eyes had the highest rate of alcohol dependency, about 80 percent higher than those with other eye colors.

Does How Well You Hear Influence How Well You See?
According to a 2015 study by life scientists at UCLA, our ability to accurately perceive where an object is located is surprisingly poor, yet is somewhat improved when auditory cues accompany visual ones.
Ladan Shams, PhD, an associate professor of psychology in the UCLA College, studied "spatial localization," or how well a person can immediately and accurately perceive where an object is. What she and her team discovered came as a bit of a shock.
The scientists played brief bursts of sound and triggered flashes of light, in various combinations, and asked 384 study participants to identify where they originated. In general, people fared poorly when the light and sound were played alone. And the ability to locate visual stimuli in the periphery was much worse than it was in the center of their visual field.
"We didn't expect these spatial errors; they're very counterintuitive," Shams said. "Spatial localization is one of the most basic tasks the brain performs."
It's interesting to note, however, that participants performed with improved accuracy when the flashes and noise were played simultaneously at the same location, indicating that how well you hear could affect how well you see, and vice-versa.
"The brain is wired to use information from multiple senses to correct other senses," Shams said. "The saying is true: 'If you want to hear better, put your glasses on.'" — A.H.
