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...

US researchers have developed molten glass sewing machine by combining 3D printing of glass with a mathematical model

When the nozzle releasing a stream of molten glass is raised above a certain level, that thread begins to wobble.  It traces out waves or loops - which the team found could be controlled by adjusting the speed of the nozzle.  Those shapes then become the building blocks for intricate, 3D objects.  Engineers at the Massachusetts Institute of Technology pioneered a method for glass 3D printing in 2015. They then started to work with mathematician Pierre-Thomas Brun, who has studied the fluid dynamics of liquid "ropes".  The results are documented in a video, which the team presented in the American Physical Society's "Gallery of Fluid Motion" in November.It all started with a collaboration between two labs at MIT, Dr Brun told - one specialising in glass and the other in "mediated matter"."Normally when you 3D print, the nozzle is very close to the piece that you're printing - that's the conventional method. But what they started worki...

The world's biggest crystal structure model - a 3D chemical illustration made from little balls and sticks

It replicates the repeating lattice of sodium and chloride ions found in a crystal of salt (NaCl).  Standing more than 3m tall, the model was built by Dr Robert Krickl from nearly 40,000 balls and 10km of sticks.  The world record attempt will be adjudicated by the Guinness Book of Records on 23 November.  It will be on public display until 30 November, and has already been commemorated on an Austrian postage stamp.Because of the regular pattern it is built up from, which causes hundreds of the "ions" to form precise lines from multiple angles, the huge model has a rather dazzling appearance. It also has particular significance this week, Dr Krickl said.  "This week it's the 100th anniversary of the Nobel Prize for discovering what I show with this model: the arrangement of atoms in crystals."  The British father-and-son team of William and Lawrence Bragg won the physics Nobel in 1915 for originating the technique that is now known as X-ray crystallog...

Early Apple computer fails to sell

However, neither the Apple 1 nor the rare antique television were sold.  Apple 1 computers are usually valuable collectables. Made in 1976, there are now only about 50 left in the world.  At a similar sale last year, one fetched $365,000 (£237,000). And in 2013, another attracted a $905,000 bid.  The Apple 1 at Monday's vintage tech sale had a starting price of $300,000.  The Cray-4 processor sold for $37,500. The 1936 Baird television set may not work and delivers a huge  electrical charge of 5000 volts.  But auctioneer Bonhams had forecast that it could fetch between $20,000 (£13,000) and $30,000.He was working on the Cray-4 model when his company went bankrupt in 1995, and the following year he died in a traffic accident.  The processor, with serial number 001, was listed with an expected price tag of $50,000 - $80,000.  Other lots included an early German Enigma machine, handwritten paperwork by Albert Einstein and a 19th Century te...
