New method to understand superconductors

Dec. 12, 2012 ? Researchers at The Open University have devised a new method to understand the processes that happen when atoms cool which could lead to new materials for superconducting power grids and widespread use of magnetic resonance imaging (MRI).

In a paper, "Bilayers of Rydberg atoms as a quantum simulator for unconventional superconductors" just published in Physical Review Letters, Dr Jim Hague and Dr Calum McCormick at The Open University's Department of Physical Sciences describe a new method to understand the cooling of atoms, which is to simulate a superconductor using a "quantum simulator" (a kind of bespoke quantum computer for examining specific problems) rather than a supercomputer.

The researchers found that just such a simulator can be built to examine atoms cooled to just a millionth of a degree above absolute zero. The atoms are controlled using laser beams which enhance the electrical forces between the atoms, which are usually weak and unimportant. These forces mimic the physics of the superconductor, and the proposed simulator includes far more physical detail than ever before.

"The problem is that up to now nobody knew how to build such a material because physics of the best superconductors are extremely difficult to understand," said Dr Hague. "By studying the atoms in the quantum simulator, we expect that it will be possible to make major progress in unravelling the underlying theory of these fascinating materials. A superconductor (a material with no electrical resistance) operating close to room temperature would offer potentially revolutionary technology."

How technology can help with business presentations | Technology ...

Making an impression can make the difference between success and failure. The ability to present either a prospective business partner or investor with a document or product that is professionally designed and of the very highest quality will either seal the deal or do a lot of the hard work for you. So many times people go into business meetings in an attempt to seal investment or new business and leave empty handed with the quality of their presentation often to blame.

Presentation projector in a meetingWith new business proving to be vital for companies in order to continue trading and expanding, the time has come when only the best will do. After all, more and more people are looking to seal the same contracts as you are and if you can find a method of standing out from the crowd, aside from your professionalism, the quality of your pitch and a list of high-flying client case studies then you?ve got a foot in the door.

When it comes to making these presentations, the traditional methods of printing off a few pages using your office printer with branded pages and a slightly more fancy cover page are a thing of the past ? well, they are if you want to succeed. Nowadays it pays to invest in the very best technologies available, with firms such as Upper Case Design & Printing Cork offering to do all of your promotional work for you, so all you have to worry about is saying the right thing in the boardroom.

These services can be a huge weight off the mind of those going into the meeting, especially with so much on the line financially in difficult time for businesses of all sizes and all industries. If you can get someone to create high quality designs and marketing campaigns for you, like the graphics on your company website ? which is often the first port of call for a lot of business partners and clients who may be considering working with your firm ? or creating a DVD documenting some of your finest campaigns, even showing how you go about your business; then you?ve done a lot of the hard work in an exciting way that is likely to really engage with your VIP-audience, as that is how they should be viewed.

People looking to invest their time or money into your business want to be presented with professional-standard information and resources from professional people. You cannot take your business to the next level without going the extra mile yourselves and that involves investment in the latest technologies.

Times are changing and we are now in a world of tablet computers and DVDs as opposed to ring binders and cassettes and businesses need to adapt. A pitch cannot be won without making an impression and the best way to do this is to show that you?ve put the time, effort and money into acquiring the money or business of the people you?re meeting.

iParenting: How I keep my kids safe around tablets

12 hrs.

The FTC reminded us Monday?what many a parent knows all too well: Not all kids' apps are safe, especially where privacy is concerned. So, as a parent of two small children in a house full of tablets, what do I do to keep them safe? Here are my guidelines:

Read the reviews: Parents may be the most vocal group when it comes to app reviews, and the commentary under kids' apps will tell you almost immediately if there's a concern. If you notice a bunch of five-stars and just one or two one-star reviews, you're probably safe, but if you see an issue mentioned several times, and it strikes you as a problem, walk away. There are too many kids' apps out there?for any one to make or break your kid's day. ?

No ad-supported apps:?"Free,"?ad-supported apps?are called out by the FTC because so much information is shared with the advertiser or a third-party tracker.?Paying for apps usually means you're buying?insurance against some of this?funny business ? not just against?ads, but also in-app money-making schemes. (More on that next.)?Higher-quality?kids' apps range from $1.99 to $6.99. That may seem "steep" in the app galaxy, but that pricing is cheaper than most children's books, and app?updates usually?cost nothing.?

No in-app purchases: I am very much opposed to any kids' app that is offered for free,?only to tease a bunch of in-app purchases, like a "free" virtual?fish tank that comes with just?two fish ? but you can buy more for $1.99 a piece! That is a technique that is used to win over the kid first, so that a reluctant parent is guilt-tripped into spending money. Better for parent to?choose to spend a fixed amount up front.

No social log-ins or sharing: My kids are way too young to "share" their drawings and other?creations with the world, or care what total stranger kids out there are up to. That will change as they age, but I will always be aware of what apps make social?sharing a key focus, and I'll evaluate the risks on a per-app basis.

Wall 'em off: Though my kids are mostly on iPads, I am a fan of Amazon's FreeTime kids' service, which you can use on the Kindle Fire line of tablets. Not only do parents specify exactly what apps, books and videos their kids can use, the service blocks Web browsing and in-app purchases as a rule.?There's also a way to set time limits on different activities. Some elements of the "walled garden" approach are on other?platforms, and I expect to see even?more of this functionality from Android and iOS this year.

Play with the kids: I am pretty sure there isn't a single app that my kids have access to that I haven't played from beginning to end myself. (Usually I'm with them ... but hey, that new "Goodnight Moon" app?is entertainment at any age, and I'm pretty sure I liked "Pat the Bunny" more than either of my kids!) Joking aside, I do enjoy taking the time to play with apps with them, and to watch them interact. Doing this, I can quickly spot anything problematic about the app, and swiftly?remove it from the repertoire.

Some kids'?app publishers I recommend:

Duck?Duck Moose - From "Wheels on the Bus" to "Kindergarten Reading," there are few misses and lots of hits among the DDM lineup.

Nosy?Crow - "Three Little Pigs," "Cinderella" and other classic tales told with innovative papercraft animation.?

Loud Crow - Some of the best franchises ever ? "Goodnight Moon," Peanuts,?Sandra Boynton's goofy animals ? are brought to spring-loaded life here.

Shape Minds and Moving Images: A few simple, beautiful apps such as "Nighty Night!" and "Little Fox Music Box" with a European aesthetic.

Oceanhouse?Media?- The app home?of Dr. Seuss. Be sure to buy the apps outright, though. This publisher, though high quality, experiments with "lite" versions and in-app purchasing on free apps, so beware.

Disney - There are loads and loads of apps and games under the Disney brand, but the educational titles ??such as the new "Numbers with Nemo," with a dedicated section for parents to track kid performance ? are worth seeking out.

LOS ANGELES (AP) ? Los Angeles prosecutors on Tuesday asked a judge to revoke Lindsay Lohan's probation and schedule a hearing that could lead to the actress' return to jail.

The filing came one day before Lohan is scheduled to be arraigned Wednesday on three misdemeanor charges filed last month related to a June car crash.

Lohan will not need to be present for Wednesday's arraignment on charges she lied to Santa Monica police, was driving recklessly and obstructed an officer from performing duties related to the crash investigation. She remains on probation for a 2011 necklace theft case and could be sentenced to 245 days in jail if a judge determines her conduct was a probation violation.

Her attorney Shawn Holley did not immediately return an email seeking comment.

City attorney's spokesman Frank Mateljan said any probation violation proceedings are likely to be heard after the Santa Monica case. Prosecutors allege Lohan lied about being a passenger in her Porsche when it crashed on Pacific Coast Highway on the way to a film shoot.

The "Liz and Dick" star was released from supervised probation in March after completing several months of court appearances and morgue cleanup duty.

Lohan has yet to be booked on the new charges and a judge on Wednesday will likely set bail and the terms of her release.

HBT: Royals send prospects to Rays for 2 pitchers

UPDATE: Yes, this is much bigger. The Royals have made an official announcement:

My first take was that this was a ?big, big gamble.? Now that we know we know that the Royals have thrown in Jake Odorizzi, it goes from ?gamble? to ?malpractice.?

Odorizzi pitched two games in Kansas City in 2012, but his work on the farm has been quite nice.?In 145 total innings across Double and Triple-A in 2012, Odorizzi posted a 3.03 ERA and 135/50 K/BB ratio. And he?s just 22.

To sum up: the Royals gave up a top slugging prospect and a guy who figures to be a number three starter ? each of whom are under team control for six years ? for a veteran starter who is under team control for two years max, and a swingman who, one would assume, the Royals want to start again.

I think it?s quite possible that this trade makes the Royals better in the short term and, likewise, may make the Rays worse in the short term. But it?s not going to make the Royals good enough to seriously contend in that short term and really kills them in the long term.

Not liking this deal from the Royals perspective. Not liking it at all.

11:12 PM: This is just breaking and we don?t have all the details yet, but Mark Topkin of the Tampa Bay Times is reporting?that the Rays have traded James Shields and Wade Davis to the Kansas City Royals for outfield prospect Wil Myers. ?Jerry Crasnick of ESPN, however, is reporting that there is more to this deal than just those three players and it may involve several more players.

Not that it isn?t large already. Any trade involving Myers, who is one of the top prospects in all of baseball, is a big deal.?Myers, who turns 22 on Monday, hit .314/.387/.600 with 37 homers and 109 RBI between Double- and Triple-A last season. He strikes out a lot, but is one of the stronger power prospects to come around in a long time.

Shields needs no introduction. He?s a seven-year veteran who went 15-10 this past season with a 3.52 ERA. While never a Cy Young caliber pitcher, he has tossed over 200 innings a year ? sometimes a lot more than 200 in a year ? every season since 2007. ?Davis was once a starter but was moved to the pen last year and it did him wonders: 70 and a third innings in 54 appearances in which he posted a 2.43 ERA and struck out 11.1 batters per nine innings. He seems a way better bet as a reliever than being turned back into a starter, if Kansas City has that in mind.

Overall, though, this is a big, big gamble for the Royals. They are sending away a truly elite power prospect who has yet to log a day of major league service time for two veteran pitchers, neither of which is a real game-changer for them, even if it does make their pitching more respectable. It strikes me, though, that adding Will Myers to the lineup would do more to improve the Royals? outlook than adding a reliever and a number two starter.

(AP) ? In the lush hills of northern Thailand, a herd of 20 elephants is excreting some of the world's most expensive coffee.

Trumpeted as earthy in flavor and smooth on the palate, the exotic new brew is made from beans eaten by Thai elephants and plucked a day later from their dung. A gut reaction inside the elephant creates what its founder calls the coffee's unique taste.

Stomach turning or oddly alluring, this is not just one of the world's most unusual specialty coffees. At $1,100 per kilogram ($500 per pound), it's also among the world's priciest.

For now, only the wealthy or well-traveled have access to the cuppa, which is called Black Ivory Coffee. It was launched last month at a few luxury hotels in remote corners of the world ? first in northern Thailand, then the Maldives and now Abu Dhabi ? with the price tag of about $50 a serving.

The Associated Press traveled to the coffee's production site in the Golden Triangle, an area historically known for producing drugs more potent than coffee, to see the jumbo baristas at work. And to sip the finished product from a dainty demitasse.

In the misty mountains where Thailand meets Laos and Myanmar, the coffee's creator cites biology and scientific research to answer the basic question: Why elephants?

"When an elephant eats coffee, its stomach acid breaks down the protein found in coffee, which is a key factor in bitterness," said Blake Dinkin, who has spent $300,000 developing the coffee. "You end up with a cup that's very smooth without the bitterness of regular coffee."

The result is similar in civet coffee, or kopi luwak, another exorbitantly expensive variety extracted from the excrement of the weasel-like civet. But the elephants' massive stomach provides a bonus.

Think of the elephant as the animal kingdom's equivalent of a slow cooker. It takes between 15-30 hours to digest the beans, which stew together with bananas, sugar cane and other ingredients in the elephant's vegetarian diet to infuse unique earthy and fruity flavors, said the 42-year-old Canadian, who has a background in civet coffee.

"My theory is that a natural fermentation process takes place in the elephant's gut," said Dinkin. "That fermentation imparts flavors you wouldn't get from other coffees."

At the jungle retreat that is home to the herd, conservationists were initially skeptical about the idea.

"My initial thought was about caffeine ? won't the elephants get wired on it or addicted to coffee?" said John Roberts, director of elephants at the Golden Triangle Asian Elephant Foundation, a refuge for rescued elephants. It now earns 8 percent of the coffee's total sales, which go toward the herd's health care. "As far as we can tell there is definitely no harm to the elephants."

Before presenting his proposal to the foundation, Dinkin said he worked with a Canadian-based veterinarian that ran blood tests on zoo elephants showing they don't absorb any caffeine from eating raw coffee cherries.

"I thought it was well worth a try because we're looking for anything that can help elephants to make a living," said Roberts, who estimates the cost of keeping each elephant is about $1,000 a month.

As for the coffee's inflated price, Dinkin half-joked that elephants are highly inefficient workers. It takes 33 kilograms (72 pounds) of raw coffee cherries to produce 1 kilogram of (2 pounds) Black Ivory coffee. The majority of beans get chewed up, broken or lost in tall grass after being excreted.

And, his artisanal process is labor-intensive. He uses pure Arabica beans hand-picked by hill-tribe women from a small mountain estate. Once the elephants do their business, the wives of elephant mahouts collect the dung, break it open and pick out the coffee. After a thorough washing, the coffee cherries are processed to extract the beans, which are then brought to a gourmet roaster in Bangkok.

Inevitably, the elephant coffee has become the butt of jokes. Dinkin shared his favorites: Crap-accino. Good to the last dropping. Elephant poop coffee.

As far away as Hollywood, even Jay Leno has taken cracks.

"Here's my question," Leno quipped recently. "Who is the first person that saw a bunch of coffee beans and a pile of elephant dung and said, 'You know, if I ground those up and drank it, I'll bet that would be delicious.'"

Jokes aside, people are drinking it. Black Ivory's maiden batch of 70 kilograms (150 pounds) has sold out. Dinkin hopes to crank out six times that amount in 2013, catering to customers he sees as relatively affluent, open-minded and adventurous with a desire to tell a good story.

For now, the only places to get it are a few Anantara luxury resorts, including one at the Golden Triangle beside the elephant foundation.

At sunset one recent evening in the hotel's hilltop bar, an American couple sampled the brew. They said it surpassed their expectations.

"I thought it would be repulsive," said Ryan Nelson, 31, of Tampa, Florida. "But I loved it. It was something different. There's definitely something wild about it that I can't put a name on."

His wife Asleigh, a biologist and coffee lover, called it a "fantastic product for an eco-conscious consumer," since the coffee helps fund elephant conservation.

But how does it taste?

"Very interesting," she said, choosing her words carefully. "Very novel."

"I don't think I could afford it every day on my zookeeper's salary," she said. "But I'm certainly enjoying it sitting here overlooking the elephants, on vacation."
