"  Here are some of the headlines that caught our eye at the Good Housekeeping Research Institute this week: Starbucks to Test Mobile Ordering Service If you&amp;#039;re running late, you may be able to get your coffee started ahead of time. Starbucks has just revealed a game-changing venture to let customers order beverages from mobile devices. Adam Brotman, Starbucks&amp;#039; Chief Digital Officer, says that the world&amp;#039;s largest coffee chain will begin testing the smartphone service this year in select stores. 4-Year-Olds Might Be Superior Problem-Solvers Ever experience that startling (and slightly troubling) impression that your child may be smarter than you? Turns out, there may be truth to that. According to a new study from the University of California-Berkeley, four-year-olds may solve certain logic problems better than adults do. In a test, toddlers were able to activate a machine, using a specific set of blocks, faster than their collegiate counterparts, potentially due to children&amp;#039;s abilities to kick their imaginations into high gear. Study Finds No Region of the U.S. is Allergy-Free  Those in pursuit of a refuge from allergy season may be on a wild goose chase. A new study published in The Journal of Allergy and Clinical Immunology finds that no section of the U.S. is allergy-free; rather, allergens vary based on location. Sensitivities remain the same, but those living in the West may sneeze at the smell of grass or ragweed, while Eastern inhabitants have low tolerance for mold. Vitamin D May Lower Cholesterol A new randomized study has found that vitamin D may reduce levels of LDL (the &amp;quot;bad&amp;quot; cholesterol) in the body. Scientists administered a daily dose of either 400 units of vitamin D or 1,000 mg of calcium to 576 postmenopausal women for three years, and discovered that the vitamin D group had slightly lower levels of LDL by the end of the experiment. The sample was small and no direct conclusions have been made quite yet, so stay tuned. U.S. Public Transit at Peak Ridership Public transit use in the United States is at its highest ridership since 1956, when suburb development began booming. According to data released Monday by the American Public Transit Association, Americans took a whopping 10.7 billion trips on public trains, subways, and buses in 2013. (Speaking of trains, have you heard about Amtrak&amp;#039;s new writers&amp;#039; residency?) TELL US: What was the most interesting news you heard this week?
