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 in-vitro fertilisation success paves the way for conserving endangered breeds and could help in the fight against human and animal diseases, say researchers at Cornell University. The seven beagle and cross-bred beagle-spaniel puppies were born to a surrogate mother. They were from the same litter but have three sets of parents. Frozen embryos were implanted in a female dog using techniques similar to those used in human fertility clinics. Problems with freezing embryos have caused difficulties in the past, but the group say they have perfected this and other techniques.Lead researcher Dr Alex Travis, from Cornell's college of veterinary medicine, said: "We have seven normal happy healthy puppies." He added: "Since the mid-1970s, people have been trying to do this in a dog and have been unsuccessful. "Now we can use this technique to conserve the genetics of endangered species."The researchers say IVF is a powerful tool to help endangered spe...
