Disinfectants 'Train' Superbugs To Resist Antibiotics

From The BBC:

Disinfectants could effectively train bacteria to become resistant to antibiotics, research suggests.

Scientists know bacteria can become inured to disinfectant, but research increasingly shows the same process may make them resistant to certain drugs.

This can occur even with an antibiotic the bacteria have not been exposed to.

Writing in Microbiology, the National University of Ireland team, who focused on a common hospital bacterium, urges a rethink of how infections are managed.

Amazon E-Book Sales Overtake Print For First Time

In the US, Amazon says its Kindle e-book reader is its most gifted product.

From The Guardian:

Online retailer may be on target for sales of 500,000 Kindle e-readers over Christmas.

Spare a thought for the humble hardback this Christmas. It seems the traditional giftwrapped tome is being trumped by downloads, after Amazon customers bought more e-books than printed books for the first time on Christmas Day.

As people rushed to fill their freshly unwrapped e-readers – one of the top-selling gadgets this festive season – the online retailer said sales at its electronic book store quickly overtook orders for physical books. Its own e-reader, the Kindle, is now the most popular gift in Amazon's history.

Airport Security: Why It Failed

From Live Science:

Airport screening procedures failed for many reasons to catch the Nigerian man who aimed to blow up flight 253 as it approached Detroit. Scanners that might have spotted the explosives are not fully deployed, and even at airports where they exist, the scanners aren't used on all passengers.

Bottom line: No system will likely prove foolproof, experts say.

Investigators say 23-year-old Nigerian Umar Farouk Abdul Mutallab hid an explosive device and the chemical explosive PETN on his body while traveling from Amsterdam to Detroit aboard the Delta flight on Christmas day.

Once In A Blue Moon To Happen Thursday

From Mercury News:

Once in a blue moon is about to happen.

On Thursday, a second full moon in a calendar month will appear in the night sky, an occurrence known as a blue moon.

There has not been a month with two full moons since 2007, when sky gazers enjoyed one on June 1 and again on June 30 of that year. The first full moon this month occurred on Dec. 2.

The phrase "blue moon" has nothing to do with the color of the sphere, explained Conrad Jung, a staff astronomer at the Chabot Space & Science Center in Oakland. "It's just a colloquial term, which means very, very rare," he said.

Amazon: Kindle Is Most Gifted Item Ever

From PC World:

Amazon's Kindle e-book reader hit a watershed moment on Christmas Day, when, for the first time ever, customers purchased more Kindle books than physical books. The company also claims the Kindle is the most gifted item in Amazon's history. These two facts were part of the online retailer's recently announced holiday sales activity.

But in typical Amazon style, the company did not provide any sales figures to back up its claims. Although Amazon did say that if you placed side by side all the Blu-ray disc players the company sold this season, the line would stretch for more than 27 miles. A mile has 63,360 inches, so I'll leave you to make your best guess.

The Department of Mad Scientists -- A Book Review

From New York Times:

Two years ago, in his book “Rocketeers,” Michael Belfiore celebrated the pioneers of the budding private space industry. Now he has returned to explore a frontier closer to home. The heroes of his new book, “The Department of Mad Scientists,” work for the Defense Advanced Research Projects Agency, better known as Darpa, a secretive arm of the United States government. And the revolution they’re leading is a merger of humans with machines.

The revolution is happening before our eyes, but we don’t recognize it, because it’s incremental. It starts with driving. Cruise control transfers regulation of your car’s speed to a computer. In some models, you can upgrade to adaptive cruise control, which monitors the surrounding traffic by radar and adjusts your speed accordingly. If you drift out of your lane, an option called lane keeping assistance gently steers you back. For extra safety, you can get extended brake assistance, which monitors traffic ahead of you, alerts you to collision threats and applies as much braking pressure as necessary.

Walk into your local bookstore, and all is peace and order. But the tranquility masks an industry on fire. The traditional book business is being burned to the ground by technology, by recession, by the Internet -- but mostly by Amazon.

Amazon is the best thing that ever happened to self-published authors. They offer a complete publishing service that includes editing, design, and distribution -- even into brick-and-mortar bookstores. Meanwhile, they're getting ready to dictate terms over the fast-growing eBook market. Traditional publishing is being decimated, and the future looks bleak.

How Tech Touched The '00s

From CNET News:

I've been enjoying all of the end-of-decade lists that have suddenly cropped up. I like knowing what I was intimately aware of and what I completely missed.

This week, the Associated Press came out with its list of "50 things that changed our lives in the aughts." First off, the reference to the "aughts" made me chuckle. Back in late 1999, I was concerned about two things: Y2K and what the heck we were going to call the first decade. Neither of those concerns turned out to be much of a problem in the end. "Aughts" certainly never caught on.

Imagine what browsing the web would be like if you had to type out addresses in characters you don't recognise, from a language you don't speak. It's a nightmare that will end for hundreds of millions of people in 2010, when the first web addresses written entirely in non-Latin characters come online.

Net regulator ICANN - the Internet Corporation for Assigned Names and Numbers - conceded in October that more than half of the 1.6 billion people online use languages with scripts not fully compatible with the Latin alphabet. It is now accepting applications for the first non-Latin top level domains (TLDs) - the part of an address after the final "dot". The first national domains, counterparts of .uk or .au, should go live in early 2010. So far, 12 nations, using six different scripts, have applied and some have proudly revealed their desired TLD and given a preview of what the future web will look like.

From Technology Review:

Information technology's next grand challenge will be to secure the cloud--and prove we can trust it.

In 2006, when Amazon introduced the Elastic Compute Cloud (EC2), it was a watershed event in the quest to transform computing into a ubiquitous utility, like electricity. Suddenly, anyone could scroll through an online menu, whip out a credit card, and hire as much computational horsepower as necessary, paying for it at a fixed rate: initially, 10 cents per hour to use Linux (and, starting in 2008, 12.5 cents per hour to use Windows). Those systems would run on "virtual machines" that could be created and configured in an instant, disappearing just as fast when no longer needed. As their needs grew, clients could simply put more quarters into the meters. Amazon would take care of hassles like maintaining the data center and network. The virtual machines would, of course, run inside real ones: the thousands of humming, blinking servers clustered in Amazon's data centers around the world. The cloud computing service was efficient, cheap, and equally accessible to individuals, companies, research labs, and government agencies.
