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...
Specialists say they are closer to adding to an immunization to give deep rooted insurance against any kind of influenza, in the wake of promising trials in creatures. Two different US groups have discovered accomplishment with a methodology that homes in on a steady piece of the influenza infection. That ought to evacuate the issue with current influenza immunizations which must be given over again every year in light of the fact that they concentrate on the transforming piece of the infection. The evidence of-idea work is distributed in Science diary and Nature Medicine. Studies are currently required in people to affirm that the system will work in man. Meanwhile, specialists say individuals ought to keep on accepting a yearly influenza punch in light of the fact that immunization is still the most ideal approach to ensure yourself against disease.
Routine influenza pokes target atoms on the surface of the
influenza infection, however these are continually evolving. Envision the influenza infection as a ball with loads of candies on stems standing out. The candies change year to year, however the stems continue as before. It is the stems that researchers are presently concentrating on as an objective for an all inclusive influenza poke.
Many different research teams have been testing potential candidates, but it has been a technical challenge to make something that can be used in a vaccine without involving the lollipop 'head' of the hemagglutinin molecule. This latest work seems particularly promising, according to Prof John Oxford, a flu expert at the University of London. He called the results a "red letter day" for science. "This is a leap forward compared to anything done recently. They have good animal data, not just in mice but in ferrets and monkeys too. And they've done it with the bird flu virus H5N1," he said.
"It's a very good stepping stone. Ultimately, the hope is to get a vaccine that will cover a pandemic virus." Prof Sarah Gilbert, Professor of Vaccinology at University of Oxford, said: "This is an exciting development, but the new vaccines now need to be tested in clinical trials to see how well they work in humans."
"This will be the next stage of research, which will take several years. So we are still some way from having better flu vaccines for humans," she added.
