ScienceDaily: Cars, planes and many electronic products are now built with the help of sophisticated assembly lines. The creation of such an assembly line at molecular level has been a long-held dream of many nanoscientists. "It would enable us to assemble new complex substances or materials for specific applications," said Viola Vogel of the Laboratory of Applied Mechanobiology at ETH Zurich. In a paper published in the latest issue of the Royal Society of Chemistry's Lab on a Chip journal, ETH researchers presented a molecular assembly line featuring all the elements of a conventional production line: a mobile assembly carrier, an assembly object, assembly components attached at various assembly stations and a motor (including fuel) for the assembly carrier to transport the object from one assembly station to the next. The line is around one-third the size of a human hair.
States that have legalized medical marijuana tend to experience an unexpected benefit -- fewer overdose deaths from narcotic painkillers, a new study suggests. Access to medical marijuana is associated with 25 percent fewer prescription drug overdose deaths each year compared to states where medical pot is illegal, according to findings published Aug. 25 in JAMA Internal Medicine. What's more, states that pass medical marijuana laws see their overdose death rates decrease dramatically in the years immediately afterward, researchers reported. read more
Iraqi security and volunteer forces have broken the siege of Amerli and have entered the town, news that prompted a wave of celebrations across the town which had been besieged by fighters from the terror group ISIS. The breakthrough came after the United States said it carried out airstrikes and dropped humanitarian aid in Amerli to protect an ethnic minority that one official said faced the threat of an "imminent massacre." Amerli is home to many of Iraq's Shiite Turkmen. Australia, France and the UK also participated in the aid drop.
A Queensland, Australia, farm has become the unlikely testing ground of one of the most technologically advanced Google projects: autonomous drones that could potentially deliver anything from chocolate to life-saving medicines. Google's X division tested Project Wing earlier this month, the first time "non-Googlers" had been involved. Google X director Astro Teller said Project Wing's goal is ultimately to build a system for delivering small and medium sized packages within minutes to anyone using self-flying vehicles. read more
Adam Weinstein, Atlas Shrugged readers remember Galt's Gulch as the rural refuge where Ayn Rand's Real Men of Genius spurned American socialism for their own anti-leftist paradise. Some inspired libertarians have set up a real-life Galt's Gulch in Chile. Unregulated capitalism, though, is presenting some problems! But all is not so sweet. Wendy McElroy, a "Canadian individualist anarchist" of some note, bought a 1.25-acre plot in Galt's Gulch Chile last year, or so she thought. She wrote a blistering post Monday suggesting that the Real Men of Genius behind the settlement are grifters, or incompetents, or both. read more
