Comments: 45 +-   Tapering Waveguide Captures a Rainbow on Saturday November 28, @02:51PM

SubComdTaco passes along news of researchers in the US who have trapped a rainbow in a tapering waveguide. The research is described (PDF) on the arXiv. "In 2007, Ortwin Hess of the University of Surrey in Guildford, UK, and colleagues proposed a technique to trap light inside a tapering waveguide [made of metamaterials]... The idea is that as the waveguide tapers, the components of the light are made to stop in turn at ever narrower points. That's because any given component of the light cannot pass through an opening that's smaller than its wavelength. This leads to a 'trapped rainbow.' ... Now Vera Smolyaninova of Towson University in Baltimore, Maryland, and colleagues have used a convex lens to create the tapered waveguide and trap a rainbow of light. They coated one side of a 4.5-mm-diameter lens with a gold film..., and laid the lens — gold-side down — on a flat glass slide which was also coated with film of gold. Viewed side-on, the space between the curved lens and the flat slide was a layer of air that narrowed to zero thickness where the lens touched the slide — essentially a tapered waveguide. When they shone a multi-wavelength laser beam at the... gilded waveguide, a trapped rainbow formed inside. This could be seen as a series of colored rings when the lens was viewed from above with a microscope: the visible light leaked through the thin gold film."

Comments: 197 +-   What the iPod Tells Us About the World Economy on Saturday November 28, @12:15PM

Hugh Pickens writes "Edmund Conway has an interesting article in the Telegraph where he analyzes where the money goes when you buy a complex electronic device marked 'Made in China,' and why a developed economy doesn't need a trade surplus in order to survive. For his example, Conway chooses a 30GB video iPod 'manufactured' in China in 2006. Each iPod, sold in the US for $299, provides China with an export value of about $150, but as it turns out, Chinese producers really only 'earned' around $4 on each unit. 'China, you see, is really just the place where most of the other components that go inside the iPod are shipped and assembled.' Conway says that when you work out the overall US balance of payments, it shows that most of the cash for high tech inventions has flowed back to the United States as a direct result of the intellectual property companies own in their products. 'While the iPod is manufactured offshore and has a global roster of suppliers, the greatest benefits from this innovation go to Apple, an American company, with predominantly American employees and stockholders who reap the benefits,' writes Conway. 'As long as the US market remains dynamic, with innovative firms and risk-taking entrepreneurs, global innovation should continue to create value for American investors and well-paid jobs for knowledge workers. But if those companies get complacent or lose focus, there are plenty of foreign competitors ready to take their places.'"

The Installer writes with this quote from the Associated Press: "The Treasury Department and the Federal Reserve are giving US financial institutions an additional six months to comply with regulations designed to ban Internet gambling. ... The delayed rules would curb online gambling by prohibiting financial institutions from accepting payments from credit cards, checks or electronic fund transfers to settle online wagers. The financial industry complained that the new rules would be difficult to enforce because they did not offer a clear definition of what constitutes Internet gambling. They had sought a 12-month delay in implementing provisions of the Unlawful Internet Gambling Enforcement Act that Congress had passed in 2006. ... US bettors have been estimated to supply at least half the revenue of the $16 billion Internet gambling industry, which is largely hosted overseas."

xchg writes in with a somewhat speculative, though plausible, piece from WiseAndroid claiming that Google is gearing up for an all-out assault on the mobile-phone market that will include a new, Google-branded handset and the first comprehensive Google phone service with unlimited free calls. "The real breakthrough, however, will come with the marriage of the Googlephone to Google Voice, the Californian company’s high-tech phone service. Google Voice gives US users a free phone number and allows unlimited free calls to any phone in the country — landline or mobile. International calls start from... just over a penny a minute. Google Voice also uses sophisticated voice recognition to turn voicemails into emails, can block telemarketing calls automatically and offers free text messaging. Google sounded its intentions two weeks ago when it purchased a small company called Gizmo5... [E]xperts are predicting that the Googlephone will be launched in the US early next year."

In the wake of the CRU "climategate" leak, reader Geoffrey.landis sends along a New York Times blog profile of Judith Curry, a climate scientist at Georgia Tech. "Curry — unlike many climate scientists — does not simply dismiss the arguments of 'climate skeptics,' but attempts to engage them in dialogue. She can, as well, be rather pointed in criticizing her colleagues, as in a post on the skeptic site climateaudit where she argues for greater transparency for climate data and calculations (mirrored here). In this post she makes a point that tribalism in science is the main culprit here —- that when scientists 'circle the wagons' to defend against what they perceive to be unfair (and unscientific) attacks, the result can be damaging to the actual science being defended. Is it still possible to conduct a dialogue, or is there no possible common ground?"

1sockchuck writes "The data center of the future may have no central UPS units, and be filled with servers with on-board batteries. Facebook says it will adopt a new power distribution design that shifts the UPS and battery backup functions from the data center into the cabinet by adding a 12-volt battery to each server power supply, an approach pioneered by Google. Facebook says the move will slash its power bill and save millions in capital expenses on UPS systems and PDUs. Facebook acknowledged that these types of custom designs are limited to large companies, but called on server vendors and data center builders to adapt their offerings to make them available to smaller companies."

Eugen tips news that Microsoft has sent DMCA takedown notices to several websites to stop them from offering the Computer Online Forensic Evidence Extractor (COFEE) tool for download after it was leaked earlier this month. One of the sites, Cryptome.org, has posted their correspondence with Microsoft over the software. "... Microsoft contacted Network Solutions, which hosts Cryptome, and since John Young, the owner of the website, wasn't too keen on losing his whole website for the sake of a single 15MB file, he removed the download link and sent Network Solutions a notice of compliance."

theodp writes "CNN reports that for most of the past week, when someone did a Google image search for 'Michelle Obama,' one of the first images that came up was a picture of the First Lady altered to resemble a monkey. After being hit with a firestorm of criticism over the episode, Google first banned the site that posted the photo, saying it could spread malware. Then, when the image appeared on another site, Google displayed the photo in its search results, but displayed an apologetic Google ad above it. On Wednesday morning, the racially offensive image appeared to have been removed from any Google Image searches for 'Michelle Obama.' Google officials could not immediately be reached for comment." Update — 15:38 GMT by SS: A reader pointed out that this article from the Guardian says the image was de-listed simply because it was removed from the blog where it was hosted rather than by any "deliberate" action from Google.

Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."
