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...
Three-quarters of the UK's butterflies have declined in the past 40 years, according to a report by the charity Butterfly Conservation
The study, State of the UK's Butterflies 2015, suggests 76% of resident and regular migrant butterflies have declined. Some common species have suffered what the charity calls "major slumps". Thousands of data-gathering volunteers enabled scientists to build up this long-term national picture. And Butterfly Conservation and the Centre for Ecology & Hydrology (CEH), which helped produce this report, encouraged the public to take part in surveys to help monitor trends in UK biodiversity.While the main conclusions suggest a bleak outlook for the insects, the research did reveal some rare species were benefiting from targeted conservation. According to Richard Fox, of Butterfly Conservation, one of the lead researchers, this was thanks to landscape-scale projects - protecting and restoring threatened habitats, such as managed wildflower-rich grasslands and heath-lands. The threatened Duke of Burgundy butterfly, for example, has seen a recent increase i...
