Discovered: "Whole grain" labeling doesn't mean much; brown-eyed girls (and boys) deemed more trustworthy; birds are smart enough to hide their food; heel-to-toe barefoot runners gain ground.
What does that 'whole grain' sticker really mean? Don't take this as license to binge on over-processed white bread, but Harvard School of Public Health researchers have found huge discrepancies amongst products marked "whole grain," throwing the label into question. They even found that products bearing the standardized Whole Grain Stamp are usually more sugary and caloric than products without the stamp. "Given the significant prevalence of refined grains, starches, and sugars in modern diets, identifying a unified criterion to identify higher quality carbohydrates is a key priority in public health," says author Rebecca Mozaffarian.

Never trust a blue-eyed man. When Czechoslovakian college students were shown pictures of people their age, they consistently rated brown-eyed people as more trustworthy than those with blue eyes. But eye color itself isn't the only culprit. Charles University in Prague researcher Karel Kleisner was able to demonstrate that face shape—a trait that's often genetically linked with eye color—profoundly affects trustworthiness ratings. For instance, when round-faced, brown-eyed people had their eyes photoshopped to blue, they were still deemed more trustworthy. "It was unexpected that some superficial sign like eye color could somehow be linked, by means of genes and hormones, to facial shape," says Kleisner. [Wired]
