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.

A 16-year-old French volunteer archaeologist has found an adult tooth dating back around 560,000 years in southwestern France, in what researchers hailed as a “major discovery” Tuesday.“A large adult tooth — we can’t say if it was from a male or female — was found during excavations of soil we know to be between 550,000 and 580,000 years old, because we used different dating methods,” paleoanthropologist Amelie Viallet told AFP.
“This is a major discovery because we have very few human fossils from this period in Europe,” she said. The tooth was found at one of the world’s most important prehistoric sites in Tautavel, which has been excavated for about 50 years. It is also the site of the discovery of fossils belonging to Tautavel Man, a species that lived an estimated 450,000 years ago. Volunteer Camille, 16, was working with another young archaeologist when she found the tooth.
