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.

Ghostly pale and totally blind, olms - fondly known by locals as "baby dragons" - only reproduce every 5-10 years and are thought to live to 100. This clutch of eggs started to appear in January in an aquarium in Postojna Cave, a tourist destination where the creatures have lived for millennia. Observing baby olms develop and hatch is a rare opportunity for science. The first of 23 developed eggs hatched on 30 May; a second baby olm (pictured below) was slowly wriggling out of its egg on Wednesday night."It is the end of one part of the story and the beginning of a whole new chapter: feeding and living without the egg," said Saso Weldt, who looks after and studies the olms at Postojna Cave. I was in the cave doing some other biological work. Since we have all the eggs on an IR camera, we saw that one was missing. Then you rewind and suddenly you realise, something has happened." Mr Weldt and his colleagues hope to see a full count of 23 healthy hat...
