Three Australian researchers have developed "an ion thruster that could replace the current chemical-based rocket propulsion technology, which requires huge volumes of fuel to be loaded onto a spacecraft." Slashdot reader theweatherelectric shares this article from the ABC News: An Australian-designed rocket propulsion system is heading to the International Space Station for a year-long experiment that ultimately could revolutionize space travel. The technology could be used to power a return trip to Mars without refuelling, and use recycled space junk for the fuel... It will be placed in a module outside the ISS, powered, as Dr Neumann describes, by an extension cord from the station. "What we'll be doing with our system is running it for as long as we can, hopefully for the entire year on the space station to measure how much force it's producing for how long."
In the early 2000s "it was basically a machine the size of a fist that spat ions from a very hot plasma ball through a magnetic nozzle at a very high velocity," and the researchers are now hoping to achieve the same effect by recycling the magnesium in space junk.

A report on CNBC, citing sellers, says that counterfeit problem on the platform has gotten worse after it made it easier for Chinese manufacturers to sell goods to U.S. consumers. The report gives an example of a seller Jamie Whaley who started a bedding business on Amazon that reached $700,000 in annual sales within three years. Her patented product called BedBand consists of a set of shock cords, clamps and locks designed to keep fitted bed sheets in place. Whaley found quite an audience, selling up to 200 units a day for $13.99 a set. BedBand climbed into the top 200 selling products in the home and kitchen category. That was 2013. By mid-2015, the business was in a tailspin. Revenue plummeted by half and Whaley was forced to lay off eight employees. Her sheet fastener had been copied by a legion of mostly Chinese knockoffs that undercut BedBand on price and jumped the seller ranks by obtaining scores of reviews that watchdog site Fakespot.com determined were inauthentic and "harmful for real consumers." The report adds:Spend any time surveying Amazon sellers and Whaley's narrative will start sounding like the norm. In Amazon's quest to be the low-cost provider of everything on the planet, the website has morphed into the world's largest flea market -- a chaotic, somewhat lawless, bazaar with unlimited inventory. Always a problem, the counterfeiting issue has exploded this year, sellers say, following Amazon's effort to openly court Chinese manufacturers, weaving them intimately into the company's expansive logistics operation. Merchants are perpetually unsure of who or what may kill their sales on any given day and how much time they'll have to spend hunting down fakers.

An anonymous reader shares a BBC report: A flat lens made of paint whitener on a sliver of glass could revolutionize optics, according to its U.S. inventors. Just 2mm across and finer than a human hair, the tiny device can magnify nanoscale objects and gives a sharper focus than top-end microscope lenses. It is the latest example of the power of metamaterials, whose novel properties emerge from their structure. Shapes on the surface of this lens are smaller than the wavelength of light involved: a thousandth of a millimetre. "In my opinion, this technology will be game-changing," said Federico Capasso of Harvard University, the senior author of a report on the new lens which appears in the journal Science. The lens is quite unlike the curved disks of glass familiar from cameras and binoculars. Instead, it is made of a thin layer of transparent quartz coated in millions of tiny pillars, each just tens of nanometres across and hundreds high.PetaPixel has more details.

Boing Boing reports that NASA has uploaded to its Flickr account 8400 photographs from the agency's Apollo days -- "just about every image captured by Apollo astronauts on lunar missions." The astronauts were shooting with some very nice cameras, and the results are worth seeing at 1800dpi.

sandbagger writes "The director of the U.S. government office that monitors scientific misconduct in biomedical research has resigned after 2 years out of frustration with the 'remarkably dysfunctional' federal bureaucracy. Officials at the Office of Scientific Integrity spent 'exorbitant amounts of time' in meetings and generating data and reports to make their divisions look productive, David Wright writes. He huge amount of time he spent trying to get things done made much of his time at ORI 'the very worst job I have ever had.'"
