A solar-powered airplane finished crossing the United States on Saturday, landing in New York City after flying over the Statue of Liberty during its historic bid to circle the globe, the project team said. The spindly, single-seat experimental aircraft, dubbed Solar Impulse 2, arrived at New York's John F. Kennedy International Airport at about 4 a.m. local time after it took off about five hours beforehand at Lehigh Valley International Airport in Pennsylvania, the team reported on the airplane's website. Such a pleasure to land in New York! For the 14th time we celebrate sustainability," said the project's co-founder Andre Borschberg on Twitter after flying over the city and the Statue of Liberty during the 14th leg of the trip around the globe. The Swiss team flying the aircraft in a campaign to build support for clean energy technologies hopes eventually to complete its circumnavigation in Abu Dhabi, where the journey began in March 2015.

The golden poison dart frog is considered one of the most toxic animals on Earth. A single specimen measuring two inches (five centimeters) has enough venom to kill ten grown men. Indigenous Emberá people of Colombia have used its powerful venom for centuries to tip their blowgun darts when hunting, hence the species' name. These brightly colored amphibians are among the largest of the more than 100 poison dart frog species, averaging more than one inch (two and a half centimeters) in length. They live within a tiny plot of rain forest on the Pacific coast of Colombia. And though the population in its small range is abundant, widespread decimation of the rain forest has landed this species on international endangered lists.
Their coloring, which can be yellow, orange, or pale green, depending on their particular range, is deliberately ostentatious to ward off potential predators, a tactic called aposematic coloration. Their diet includes flies, crickets, ants, termites, and beetles.
