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...
Scientists developed ultra-thin electronic skin that can measure oxygen levels when stuck to the body
The goal is to develop such "skin" to monitor oxygen levels in organs during surgery, say researchers in Japan. Tests on volunteers found the "skin" provided stable measurements of oxygen concentration in blood. The device contains micro-electronic components that light up in red, blue and green on the surface of the body. Scientists at the University of Tokyo are working on ways to display numbers and letters on the skin for health monitoring purposes. Wearable electronics are a future growth area in research, with interest in medical applications such as contact lenses that monitor glucose levels, or smart glasses. The latest findings are revealed in Science Advances. "The device unobtrusively measures the oxygen concentration of blood when laminated on a finger," said lead researcher Tomoyuki Yokota and colleagues. He added: "Ultimately, flexible organic optical sensors may be directly laminated on organs to monitor the blood ox...
