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.

According to the work in the Journal of Medical Entomology, the blood-sucking insects love black and red but hate yellow and green. This information could help make better traps to lure and catch the bugs. But it is too soon to say if yellow sheets can stop them nesting in your bed, say the US researchers.Bed bugs are tiny and they like to live close to their next meal - your blood. They can hide in the seam of your mattress or a joint in your bed frame. They tend to prefer fabric and wood over plastic and metal. But Dr Corraine McNeill and colleagues wanted to find out if colours affected where bed bugs might dwell. They carried out a series of experiments in their lab, placing bed bugs in dishes with different colour shelters made out of card. Rather than taking cover at random, the bugs appeared to select the shelters according to their colour, showing a preference for black and red.Dr McNeill said: "We originally thought the bed bugs might prefer red...
