Imagine something as massive and towering as the Andes Mountains not having an effect on its surroundings. When it comes to computer simulations that help predict the weather, traditional global models operate poorly represent the mountain chain, which is more than 4,000 miles long, 300 miles wide [...]

It's not often that a group of eight women college students visits rural farming areas of Ghana. A simple act by a village queen the students met soon after their arrival helped erase any potentially awkward situations. Her gesture not only put the visiting Americans more at ease, but also provided [...]
