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 new investigation challenges the previously held view that this unusual looking creature is related to North American ancestors of deer. Scientists say the new study will help us better understand the evolution of cranial features such as horns, as well as the evolution of land ecosystems. For the last 40 million years, ruminants have represented a big proportion of the world's large herbivores. Ruminants include cattle, sheep, goats, deer, giraffes, antelopes, camels, and other extinct species. Palaeomerycids, now extinct, were strange-looking three-horned ruminants found in many areas, from Spain to China, some 5-23 million years ago, during what is termed the Miocene Period. Dr Israel Sánchez and his collaborators from the Museo Nacional de Ciencias Naturales in Madrid, Spain, studied well-preserved remains of a new palaeomerycid - Xenokeryx amidalae.The skull was in particularly good condition and it included teeth, as well as the three h...
