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 solar cr...
An international scientists unearthed fossils of reptile and amphibian in Brazil, dating from 278 million years ago
The fossils include two new species of "dvinosaur" - extinct cousins of modern salamanders - which were about 40cm long, one of them with fangs and gills. South America's oldest ever terrestrial reptile skeleton was also in the haul. The finds are reported in the journal Nature Communications. The ancient reptile is a lizard-like creature called Captorhinus aguti, previously only found in North America. These discoveries, all from north-eastern Brazil, are noteworthy because little is known about the plants and animals that occupied this region during the Permian period; the southern tropics of the "supercontinent" Pangaea are not well-populated by fossil finds.One of the study's co-authors, Dr Martha Richter from the Natural History Museum in London, said: "This discovery is remarkable as most of what we understand about the evolution and adaptation of amphibians through time is based on animals located in Europe and North America. "No...
