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...
The global trade in bees is driving a pandemic that threatens hives and wild bees, UK scientists say
A deadly bee disease has spread worldwide through imports of infected honeybees, according to genetic evidence. Stricter controls are needed to protect bees from other emerging diseases, researchers report in Science journal. The virus together with the Varroa mite can kill-off whole hives, putting bee populations at risk. Lead researcher Dr Lena Bayer-Wilfert of the University of Exeter said European bees are at the heart of the global spread of what she calls a "double blow" for colonies. "This is clearly linked to the human movement of honeybee colonies around the globe," she told. "It shows a piece of evidence we can't argue with." The pattern of the spread shows the movement of the virus around the world is manmade rather than natural, say scientists. Co-researcher Prof Roger Butlin of the University of Sheffield said Deformed Wing Virus (DWV) was a major threat to honeybee populations across the world with the epidemic "drive...
