Solar plane lands in New York City

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...

The Amazon entrepreneur Jeff Bezos claimed success on the second flight of his New Shepard spaceship

Intended eventually to carry people just above the atmosphere, the re-usable vehicle launched from west Texas on Monday with no-one aboard.  Both parts of New Shepard - the capsule and its propulsion unit - landed safely, Mr Bezos' company said.  On the maiden outing in April, the propulsion module was lost on the way down because of a hydraulic failure.  True to his way of working, the US billionaire gave no specific notice of the flight, stating last week only that another mission would occur "very soon".  This means all the video and information about the event have come out directly from Mr Bezos' space operation, Blue Origin.New Shepard has the capability to transport six individuals to just above 100km in altitude. It reached this mark during Monday's test, ascending to 329,839ft (100.5km).  Its propulsion unit is designed to take off and land vertically so that it can be used time and time again.  Following the test flight, that unit touched dow...

More than half of all tree species in the Amazon face extinction, warn international scientists

According to new data, up to 57% of all Amazonian trees may already fit the criteria of being globally threatened.  If confirmed, the estimates would raise the number of threatened plant species on Earth by almost a quarter.  Forest cover in the Amazon has been shrinking for decades, but little is known about the impact on individual plant species.  The trees at risk include iconic species like the Brazil nut tree, food crops such as cacao, the source of chocolate, as well as rare trees that are almost unknown to science.  The research, published in the journal, Science Advances, compared data from almost 1,500 forest plots with maps of current and predicted forest loss to estimate how many tree species have been lost and how many are likely to disappear by the middle of the century. It found that the Amazon - the world's most diverse forest - could be home to more than 15,000 tree species.  Of these, between 36% and 57% are likely to qualify as being g...

Amazon is taking legal action against more than 1,000 people for fake reviews on its website

The US online retail monster has recorded a claim in Seattle, Washington.  It says its image notoriety is being harmed by "false, deceptive and inauthentic" audits paid for by venders looking to enhance the request of their items.  It comes after Amazon sued various sites in April for offering fake surveys.   Amazon says the 1,114 respondents, termed "John Does" as the organization does not yet know their genuine names, offer a false survey administration for as meager as $5 (£3.24) on the site Fiverr.com, with most encouraging five-star audits for a vender's items.  While little in number, these audits can fundamentally undermine the trust that customers and by far most of venders and producers place in Amazon, which thus stains Amazon's image," the innovation goliath said in its protestation, which was recorded on Friday.  Amazon said it had directed an examination, which included buying fake client audits on Fiverr from individuals who gua...
