Amazon Milk Frogs, also known as Mission Golden-eyed Tree Frogs or Blue Milk Frogs, were first found in Rio de Janeiro's Maracanã River. The name "Milk Frog" refers to the poisonous, white, milky secretion that this frog secretes when threatened. But what about that blue mouth? This species is most active at night and is known for its loud vocalizations.
A recent pilot program conducted by Cornell University researchers experimented with giving children "nutrition report cards." At a K-12 school district in rural New York state, 27 parents received weekly emails describing what their children selected at the school cafeteria.
Modern-day athletes often nurse their muscles with supplement shakes or chocolate milk after a workout. Similarly, gladiators, the sports stars of the Roman Empire, may have guzzled a drink made from the ashes of charred plants — a rich source of calcium, which is essential for building bones, researchers report this month in the journal PLOS One.
"Plant ashes were evidently consumed to fortify the body after physical exertion, and to promote better bone healing," Fabian Kanz, a forensic anthropologist at the Medical University of Vienna who led the research, said in a statement. "Things were similar then to what we do today."
