New analysis sheds light on ancient Egyptian mummification

A detailed study of 150 mummies embalmed over thousands of years in ancient Egypt indicated that what we think we know about ancient mummification practices might be wrong.

Contrary to reports by famous Greek historian Herodotus, the ancient Egyptians probably didn't remove mummy guts using cedar oil enemas, new research on the reality of mummification suggests.

The ancient embalmers also didn't always leave the mummy's heart in place, the researchers added.

The findings, published in the February issue of HOMO ? Journal of Comparative Human Biology, come from analyzing 150 mummies from the ancient world.

Mummy history

In the fifth century B.C., Herodotus, the "father of history," got an inside peek at the Egyptian mummification process. Embalming was a competitive business, and the tricks of the trade were closely guarded secrets, said study co-author Andrew Wade, an anthropologist at the University of Western Ontario.

Herodotus described multiple levels of embalming: The elites, he said, got a slit through the belly, through which organs were removed. For the lower class, mummies had organs eaten away with an enema of cedar oil, which was thought to be similar to turpentine, Herodotus reported. [See Images of Egyptian Mummification Process]

In addition, Herodotus claimed the brain was removed during embalming and other accounts suggested the heart was always left in place.

"A lot of his accounts sound more like tourist stories, so we're reticent to take everything he said at face value," Wade told LiveScience.

Mummy tales

To see how eviscerations really took place, Wade and his colleague Andrew Nelson looked through the literature, finding details on how 150 mummies were embalmed over thousands of years in ancient Egypt. They also conducted CT scans and 3D reconstructions on seven mummies.

The team found that rich and poor alike most commonly had the transabdominal slit performed, although for the elites?evisceration was sometimes performed through a slit through the anus.

In addition, there wasn't much indication that cedar oil enemas were used.

Only a quarter of mummies had their hearts left in place. The removal of the heart seems to coincide with the transition period when the middle class gained access to mummification, so getting to keep the heart may have become a status symbol after that point, Wade said.

"The elites need some way to distinguish themselves from the people that they're ruling," he said.

And whereas Herodotus had suggested mummies had their brains removed and discarded, Wade and his colleagues found about a fifth of the brains were left inside the mummies' skulls. Almost all the others were pulled out through the nose, Wade's team described in another study detailed in the August 2011 issue of the same journal

After the evisceration, the bodies were rubbed down with a mild antiseptic such as palm wine. They were also covered with packets of natron, a naturally occurring salt, left to dry out for many days, packed with linen or wood shavings, and sometimes perfumed with scented items, Wade said.

Varied traditions

The findings show just how varied embalming techniques were in the ancient world, said David Hunt, a physical anthropologist at the Smithsonian Institution in Washington, D.C.

"A lot of people have taken the idea that it was all done the same way, but over the course of 3,000 years? Heck no," Hunt told LiveScience. "We know that folks in the Sudan didn't follow the exact same methodology as people that were in Alexandria."

(CHICAGO) Platelet rich plasma (PRP) therapy has been used to manage pain associated with torn tendons, muscles and ligaments, mostly in athletes, at all levels. Though it has anecdotally been successful, the evidence to support its efficaciousness is weak. Researchers at the Rothman Institute at Jefferson participated in a multi-center randomized prospective study to evaluate the clinical value of PRP versus an active control group to determine its effectiveness in managing the pain and tenderness associated with tennis elbow.

The results will be presented on Thursday, March 21, 2013, at 5 pm, McCormick Place, Room N427 at the annual meeting of the American Academy of Orthopedic Surgeons (AAOS) in Chicago.

Tennis elbow, lateral epicondylar tendinopathy, is characterized by pain radiating from the outside of the elbow to the forearm and back of the hand when grasping or twisting. The pain associated with tennis elbow can be chronic and severe.

Researchers examined 230 patients with chronic tennis elbow. All had at least three months of symptoms and had failed conventional therapy. One hundred sixteen received treatment with PRP and 114 were in the control. All received .25 percent of the anesthetic bupivacaine with epinephrine, then the PRP group received one injection of PRP placed in the extensor tendon. Both groups were followed for up to 24 weeks. No differences were noted between the PRP and control groups prior to treatment.

PRP was prepared from venous whole blood via a desktop centrifuge and disposable canister at the point of care. The centrifuge separated the platelet-rich plasma, concentrated platelets and white blood cells, which were then injected at the site of the patient's injury. In theory, the growth factors that platelets secrete (not including human growth hormone) spur tissue recovery.

At 12 weeks, the PRP patients reported 55 percent improvement in their pain scores compared to 47 percent in the active control group. At 24 weeks, the PRP patients reported 71 percent improvement compared to 56 percent in the control group.

At 12 weeks, 37.4 percent of patients in the PRP group reported significant elbow tenderness versus 48 percent in the control group. At 24 weeks, the numbers again reflected this trend: 29 percent of PRP patients had significant tenderness versus 54 percent in the control. No significant complications occurred in either group.

The study showed the efficacy and level of results that can be obtained when using PRP as part of a treatment regimen. PRP is safe and results in improvements in pain scores and local tenderness compared to an active control group.

Smartphone hacking comes of age, hitting US victims

Security researchers at Symantec warn that the next target for hackers will be your mobile device. NBC News' Bob Sullivan gets a demonstration of just how easy it is to hack a phone.

By Bob Sullivan, Columnist, NBC News

Devastating cellphone hacks that hijack your most personal gadget and rob you of privacy and money have long been forecast. But even as smartphone users in Asia are beginning to suffer exploding bills and emptied bank accounts at the hands of hackers, U.S. users largely remain safe and blissfully unaware of the gathering threat.

Not for long.?

Criminals have been probing the systems that protect?U.S. smartphone users for years, searching for the right combination of programming tricks and social engineering that would allow them to sneak onto users' phones. Recently, one hacker group hit the jackpot.

They took a year-old mobile virus named NotCompatible, which allows hackers to take complete control of a phone, and posted the malicious code on websites. Then they sent out enticing spam emails with links to the booby-trapped sites. The emails were all the more tempting because they appeared to come from friends or others on the recipients? contact list.? Victims who clicked on the link from their phones and downloaded the file surrendered control of their Android phones to the criminals. Security firm Lookout says 10,000 customers per day are still being tricked to click on the bogus link and landing on the booby-trapped pages, and virtually all of them are in the U.S.

Tim Strazzere, Lookout?s lead research and response engineer, said the sudden "staggering increase" in detection of the of the NotCompatible, which initially appeared one year ago, shows that the marriage of spam and mobile malware might be a recipe for real trouble.

"This Android malware is unique," he said. "It's exactly the same scheme and end game as before, but it's just being circulated through different means. And it's working."

U.S. smartphone users have been spared much grief from mobile malware so far for a variety of reasons. Chief among them: Most users get their apps from a centralized and safe source. Apple keeps tight controls on its App Store, so malware writers are largely ignoring that platform. And while Google's Play Store for Android is not as tightly controlled, criminals haven't had much luck sneaking infected software onto that platform, either. ?That leaves hackers with time-consuming, clumsy methods, such as tricking users to visit a rogue website and electing to install an app.

Android attackers in other parts of the world have an easier time. In China, for example, it's hard to access Google's Play store, so consumers often get their apps from websites. That means rogue apps on random websites raise less suspicion.

But Strazzere warns that the criminals behind NotCompatible have found a way to make U.S. users almost as vulnerable as those in Asia ? a direct email invitation from a friend to install what turns out to be a bogus app.

Those who might dismiss this scenario should beware: Last month, when a report by Mandiant Corp. alleged that hundreds of U.S. companies had been hacked by an arm of the Chinese military, the initial method of attack was almost the same -- a "spear-phishing" email that appears to come from a co-worker or friend, sent to entice the recipient into clicking on a virus-laden link.

Smartphone users might fear that a criminal with access to their devices might destroy all their data, "brick" the phone or prank call all their contacts. But the real nightmare from a hacked phone is much more subtle, and can be much more expensive, than having to replace a phone.

While the threat from foreign hackers is grabbing headlines, some security experts look ahead to networked devices and wonder whether your refigerator might be more vulnerable than your PC.

Vikram Thakur, a researcher at Symantec Corp., studied one mobile phone hacker who turned compromised devices into an estimated $1 million annually.

?We found a mobile phone botnet, which had ? maybe 200,000 cellphones which were compromised and in control of just this one person," he said. "(He) was able to send text messages, make these phones view videos, which were in turn giving him money; and he was doing so about 25,000 times a day."

Cellphone hackers don't do anything to call attention to themselves. Instead, their programs are designed to run in complete silence, in the background.? And they cover their tracks. There's no log of calls placed to dicey overseas numbers, no evidence of text messages sent that can run up a monthly bill.

?Your phone bill might have extra data usage toward the end of the month,? Strazzere said.? "That might be the only way you'd know."

Hackers around the world have clearly trained their attention on the fertile ground of phone hacking. Kaspersky Labs, another security firm, says there has been "explosive growth," and offers numbers to back that up. In January 2011, it counted only eight new malicious mobile malware programs. At the end of 2012, it counted 6,300 such programs monthly.

Nearly all of that activity has until now targeted overseas users, sometimes with devastating results. A program aptly named "BillShocker" by researchers infected 620,000 users earlier this year, mostly in China, and ran up hefty bills through premium text message services.

Mobile malware writers are also developing hybrid threats designed to counterattack online banking security systems.? In one sophisticated attack, criminals hacked both a victim's computer and cellphone, then lurked until an online banking transaction was initiated on the PC. When the bank sent a so-called "out of band" text message as a security confirmation, the criminals intercepted them and approved the transactions. A malicious program named Eurograbber is blamed for stealing $47 million from 30,000 bank accounts this way, according to a report by security firm F-Secure.

Those victims were in Europe, but now there are other indications that mobile hackers are circling the waters, aggressively looking for more ways into the U.S. market. ?

Computer security expert Brian Krebs reported earlier this month on his blog that criminals are selling authorized Google Play developer accounts on underground bulletin boards.? A developer account would theoretically give a criminal the ability to post rogue software onto the Google Play store.

NotCompatible is a little less ambitious. Its main goal is to control a smartphone and turn it into a "proxy" device for overseas criminals, so they could pretend they were ordering expensive merchandise from within the U.S.? Because many online sellers use geographic location to filter out fraud, and many trust cellphone location information, a hacked phone can be a perfect tool for foiling fraud-fighting software.

"Companies block transactions when someone in Romania is trying to buy concert tickets in the U.S., for example," said Strazzere.? "NotCompatible allows them to hide where they are coming from ... gives them a little more mobility based on where they want to come from. With a hacked cell phone, they will look like they are where the endpoint is."

Strazzere sees the blended threat ? part virus, part spam ? as ushering a new style of cellphone attacks, just as such blended threats gave hackers the upper hand in the personal computer world during the last decade.

?This shows the progression of malware authors and what they are doing to experiment,? he said.? It also shows impressive coordination in attacks. ?It?s still a new space for them. But they are figuring things out.?

Popgadget Personal Technology for Women: SensoGlove : Improve ...

Until they develop a robot to play golf FOR me, my game probably won't improve. (Actually, I'm sure the robot has already been developed but I just happen to own it.)
So I'm going to give the SensoGlove a try.

How it works:

The built-in digital computer actively monitors your grip with sensors placed strategically throughout the glove, providing instant feedback at all the points of your swing. SensoGlove?s audio feedback warns you at the moment your grip becomes too tight, allowing you to learn and maintain correct grip pressure at every point of your swing.

Even novice golfers like me know that your grip affects every aspect of the game, from chipping to driving. If SensoGlove can teach me to avoid the "death grip" maybe, just maybe, my score will improve.

Since the lightweight digital computer can be removed and replaced without removing the glove, you can use it only when you need it. Heck, I might just wear it all the time.

$89 for the women's and yes, you can get it for the left hand as well. At SensoGlove.

Writing Your Resume (It's Not What You Think) | Six Pixels of ...

How is your career going? How is your life going?

Do you lead a charmed life? Do you wish that every day was Groundhog's Day? Are you, literally, sucking the juice out of every day and accomplishing everything that you had hoped to accomplish? My guess is that there are very few people who can truly make these claims of unbridled glee. We live in an anxiety-riddled society, where even the people we look up to as the top performers suffer from the same stress, fears and concerns that the rest of us do. In short: life isn't easy. Being all Zen and at one with the quiet of the earth may be the daily spiritual ascent of monks and those fascinated with the new age, but for the vast majority of us (and I count myself as one of them), even a rigorous and regular schedule of meditation and relaxation is less about finding that Zen, and more about holding the anxious wolves at bay, if but for a few moments of solace in an otherwise calendar-packed day of meetings, assignments, pressures and more from both work and home.

Shoring it all up.

There is no clear-cut answer to happiness. You can read books, speak to a professional, carve out moments to find your balance and more, but in the end we all have bills to pay, expectations from others that need to be fulfilled and our own, personal development to satisfy. Even when things are going well and money becomes less of an issue of survival, many of us begin to look at what's next. Where is all of this taking us? What will make us happy now and tomorrow? When it comes to work, the layers of complexity are magnified. I am currently reading Lean In, the first business book by Sheryl Sandberg (of Facebook fame). It makes many strong (and some might say, controversial) statements about women in the workplace. It's an issue that I never understood, thankfully, because I entered the workplace without having knowledge that there was a time and place when women weren't welcome. I also chose work environments where there was always a near-even balance between men and women (and lots of diversity, I might add). In the handful of positions that I have held, two of those instances had me working for women bosses. I recall being at chamber of commerce event over a decade ago and someone asking me what it was like to have a woman for a boss. That question stopped me dead in my tracks. It was never even a thought in my mind, and it was also something that I didn't realize would be on someone else's mind. Sadly, it turns out that I may be in the minority.

What's a woman (and man) to do????

Several months ago, I had the honor of speaking to the senior-most marketers of Mattel (Barbie, Hot Wheels, Matchbox, etc...). During dinner, there was an "Inside The Actor's Studio" component with three members of the leadership team. All of them were women. During the Q&A segment, one of the team members asked these leaders for the one piece of advice that has always stuck with them. One person on the panel said that her father told her as she entered the workforce this: "Remember, every day you are writing your resume."

Every day you are writing your resume.

What seemed like powerful advice from a loving father to a very business-driven daughter is a line that transcends gender, race, skill level and occupation. We worry about what how complete our LinkedIn profiles are. We spend countless hours gossiping about company policies or others within our own team. We're worried with everybody else's level of compensation and acknowledgements, when - in reality - so few of us spend much time - each and every day - making sure that we're writing our own resume.

There are power in words. There are power in actions.

Not a day goes by since hearing that story in late January that those words don't ring in my head. Multiple times a day. For me, it has become a key driver in focus and in creating the future that I hope to have. It certainly does take away the lazy and makes me choose activities that can help me write a better resume - whether it's spending thirty minutes on a stationary bike instead of watching Auction Kings or writing a blog post instead of getting lost in Facebook's newsfeed or thinking up a strategy for a client at Twist Image instead of wondering who I am meeting for lunch. Choices. We all make choices. If I'm going to spend the majority of my waking hours thinking about the business, it may as well have the hue of writing a better resume for myself anchored to it.

So, what are you doing to write your own resume every day? What words inspire you daily to do more?

Discovery of first motor with revolution motion in a virus-killing bacteria advances nanotechnology

Scientists have cracked a 35-year-old mystery about the workings of the natural motors that are serving as models for development of a futuristic genre of synthetic nanomotors that pump therapeutic DNA, RNA or drugs into individual diseased cells. Their report revealing the innermost mechanisms of these nanomotors in a bacteria-killing virus and a new way to move DNA through cells is being published online today in the journal ACS Nano.

Peixuan Guo and colleagues explain that two motors have been found in nature: A linear motor and a rotating motor. Now they report discovery of a third type, a revolving molecular motor. Guo pointed out that nanomotors will open the door to practical machines and other nanotechnology devices so small that 100,000 would fit across the width of a human hair. One major natural prototype for those development efforts has been the motor that packages DNA into the shell of bacteriophage phi29, a virus that infects and kills bacteria. Guo's own research team wants to embed a synthetic version of that motor into nanomedical devices that are injected into the body, travel to diseased cells and pump in medication. A major barrier in doing so has been uncertainty and controversy about exactly how the phi29 motor moves. Scientists thought that it worked by rotating or spinning in the same motion as the Earth turning on its axis.

In their ACS Nano paper, Guo, with his team Zhengyi Zhao, Emil Khisamutdinov and Chad Schwartz, challenges that idea. Indeed, they discovered that the phi29 motor moves DNA without any rotational motion. The motor moves DNA with a revolving in the same motion as the Earth revolving around the sun. "The revolution without rotation model could resolve a big conundrum troubling the past 35 years of painstaking investigation of the mechanism of these viral DNA packaging motors," the report states.

HTC Interview About Samsung Galaxy S4 - Business Insider

Kevin Smith/Business Insider

HTC's street marketing team at the Galaxy S4 event.

Apple isn't the only smartphone maker going on the defensive against Samsung's new Galaxy S4.

HTC, Samsung's biggest Android rival, has been reaching out to several outlets since the GS4 announcement to give its take on the device. It also hired a street marketing team to pass out free snacks plus some coupons for its next flagship phone, the HTC One, to people waiting in line outside of Samsung's GS4 launch event at Radio City Music Hall.

We spoke to Mike Woodward, President of HTC North America, this morning for his take on the GS4.

"It feels very iterative. It looks a lot like the Galaxy S III," Woodward said of the GS4. "We were pleased to see no innovation in the design itself."

Woodward went on to criticize the Galaxy S4's slew of new software features as gimmicky, and said users probably won't be interested in them.?

So what would they be interested in?

Woodward rattled off a slew of the HTC One's own features, which has a new user interface called Sense 5 that pulls in live content from partners like ESPN and social networks like Facebook and Twitter.?The One also has an all metal and glass design, while the Galaxy S4 stuck with a plastic construction.

But it seems like an odd argument, considering it doesn't quite address how the HTC One would be a better choice for people. Many of these features are a matter of personal preference.

Look, we get that HTC is the underdog here, but it's not because they make bad products. The HTC One is a stunningly gorgeous phone, and early reviews are really good. HTC also makes the best Windows Phone you can buy.

Unfortunately, HTC is at a huge disadvantage because Samsung has a massive marketing budget. HTC is correct in its assessment that Samsung is able to essentially buy a lot of its hype.

"I think Samsung is trying to overwhelm us with money and marketing and then pushing multiple features out there," Woodward said.?

Woodward said HTC can't match Samsung's marketing budget now, but will be able to get more aggressive in the future as it sells more devices.

This isn't a story about who makes the best phone. It's about who has the best messaging.

Yo! Rocky's South Philly row house for sale

Erika Riggs , Zillow ? ? ? 1 day

From the outside, Rocky Balboa?s row house looks exactly as it did on the big screen in 1979. The brick home played host to the Italian Stallion, played by Sylvester Stallone, in ?Rocky II.? While the interior isn?t shown in the film, the street and front stoop are featured in several scenes, including Rocky?s 4 a.m. training sessions.

The home was chosen by ?Rocky? producers because they liked the look of the building. The homeowners who worked with the film production company recently passed away, real estate agent Joe Bianco told the Associated Press.

Built in 1920, the Richmond-area building today is a 3-bedroom, 1-bath row house measuring 1,036 square feet and listed for $139,000, just above Philadelphia?s median home value of $106,700.

How to disable iMessage alerts for people that aren't in your contacts

If you use iMessage frequently for both work and personal, there may come times when you don't want to be disturbed by messages from people you don't know. iMessage gives you the ability to disable alerts from people that aren't in your Contacts app. You'll still receive the messages, you just won't receive audible alerts for messages from people you don't know.

This is how to change your settings:

1. Launch the Settings app from the Home screen of your iPhone or iPad.
2. Tap on Notifications.
3. Scroll down and find Messages. Tap on it.
4. Now scroll down towards the bottom and you'll see a section for who you receive iMessage alerts from. Tap the option for My Contacts Only.

That's it. You'll now only receive alerts for messages from people you have in your contacts. It is worth noting though that this feature only works for iMessage alerts. If someone not using iMessage sends you a regular text, you'll still receive it and get an alert.

Thuraya opens communication lines for freelance journalists ...

T. Sanford Jewett, Vice President of Marketing at Thuraya, said, "Thuraya is proud to sponsor Sebastian and his work. In tough environments where he operates, communications infrastructure can be unreliable or insecure. Many leading global news organizations currently rely on Thuraya's technology to deliver breaking news. We believe that the Thuraya IP+ will provide Sebastian with an added layer of security and protection, in addition to facilitating his work by allowing him to file breaking news stories with videos and photos on time. The Thuraya IP+'s 'always-on' mobile broadband access and asymmetric streaming capabilities allows him to stay in close contact with his loved ones too."

Sebastian Meyer, freelance photographer, multimedia journalist and co-founder of Iraq's first and only photo agency called Metrography, said, "Infrastructure here in Iraq is in terrible shape with electricity cuts part of our daily life. For reporters and photographers who need to file their work on time, this can be a serious problem as communication lines often fail. Thuraya's IP+ satellite broadband terminal for Metrography will be a significant help in delivering stories from corners of the country often cut off from electricity and the Internet."

Tina Carr, Director of the Rory Peck Trust, concurred, "Safety and security are of utmost importance for freelance journalists today. We are pleased to partner with Thuraya in providing mobile satellite connectivity to Sebastian to help him in stay connected and support his work in delivering important stories from the region."

Teen sexting, the gender gap

Public release date: 14-Mar-2013

Sexting: Involves sending sexually explicit messages and/or photographs, primarily between mobile phones using the SMS system was first reported in 2005. It is an obvious portmanteau of "sex" and "texting"; the word was added to the Merriam-Webster's Collegiate Dictionary in August 2012. 4% of mobile phone-owning teens claim to have sent sexually suggestive, nude or nearly nude images or videos of themselves to someone else via a mobile device while 15% claim to have received such material from someone they know.

With contract cell phones and cheaper multimedia messaging services it is easier and cheaper than ever to share information, images and other data. Ran Wei of the School of Journalism and Mass Communications at the University of South Carolina and Ven-Hwei Lo of the School of Journalism and Communication of the Chinese University of Hong Kong, examined the effects of teen sexting that involves serious privacy and personal safety issues. One observer has suggested that the desire for risk-taking and sexual exploration among teens, coupled with a perpetual connection with peers via mobile telephony, creates a "perfect storm for sexting."

The USC-Hong Kong team has now carried out a survey of 236 adolescents in the USA, the results of which reveal that teenagers believe sexting to cause more harm to other people than to themselves. Moreover, they also consider that sext messages subsequently posted to the Internet on social networking sites and elsewhere are more harmful than those messages that are shared en masse among a group of phone users. However, they also felt that consensual sexting between two people was less harmful.

The survey also revealed a strong gender gap with regards to third-person perception of sexting: both males and females believed other females were more harmed by sexting. This perception of girls, not boys, as the victims of sexting is perhaps a common theme in sexual culture and predates telecommunications by several centuries if not longer I'd say. The survey did reveal that this gender gap meant many respondents were willing to support restrictions on sexting, but those who participated in this activity were less keen on the application of restrictions.

"Sexting raises a new issue with far-reaching social consequences for teenagers because it spans the boundaries of interpersonal communication and mass mediated communication," the team explains. "In addition, sexting poses a challenge in defining the boundary between what is socially appropriate and what is inappropriate in various communication contexts." They point out that fun or flirtatious messages between two teenagers in a romantic relationship might be shared outside that relationship to a large audience on wireless networks or the internet, causing psychological, social, cultural, and legal problems. Indeed, there have been numerous legal cases involving high-school students who have sexted in recent years.

"Sexting among teens is characteristic of an expected negative message from the perspective of parents, educators, and law enforcers," the team concludes. "When sexting is no longer confined to two people in a romantic relationship, to be vulnerable to sexting implies that sext messages may end up in the hands of predators and have a long-term harm on a teen sexter's future."

Researcher breaks Pi calculation record with the help of NVIDIA

Yesterday's self-congratulatory pat on the back to anyone reciting Pi to ten digits might feel a bit inadequate compared to Santa Clara University's Ed Karrels. The researcher has broken the record for calculating Darren Aronofsky's favorite number, taking the ratio to eight quadrillion places right of the decimal. Given the location of the University, you'll be unsurprised to learn which hardware maker's gear was used to break the record. Karrels will be showing off the new digits at the GPU technology conference in San Jose, demonstrating the CUDA-voodoo necessary to harness all of that Kepler-based computing power.

China appoints Li Keqiang as new premier

BEIJING (Reuters) - China's legislature formally chose Li Keqiang as premier on Friday, installing an English-speaking bureaucrat as the man in charge of the economy, the world's second-largest, and its aim of reviving growth through consumer-led expansion. The largely rubber-stamp National People's Congress, as expected, chose Li, 57, to replace Wen Jiabao.

Voters deliver backlash over Greenland's minerals rush

NUUK (Reuters) - Aleqa Hammond looked set to be Greenland's first female prime minister on Wednesday after winning 42 percent of votes in elections on a platform of greater control and heavier taxation of foreign mining. The opening of the country of 57,000, which is a quarter the size of the United States, to foreign miners has sparked a backlash from its traditional Inuit people, many of whom fear both Chinese influence and environmental damage.

Canada eyes "Buy America" relief in Trans-Pacific pact

WASHINGTON (Reuters) - Canada is pushing hard in trade talks with the United States and nine other countries for changes to U.S. "Buy America" provisions that have complicated cross-border trade, a top Canadian official said on Friday. "Those provisions don't only have a negative impact on Canada, they have a negative impact on American businesses who are dependent on our integrated supply chains," Canadian Trade Minister Ed Fast said in an interview.

Syria threatens to strike at rebels in Lebanon

BEIRUT (Reuters) - Syria has warned it may strike at rebels hiding in neighboring Lebanon if the Lebanese army does not act, as its patience "is not unlimited", the state news agency SANA said on Friday. Syria's Foreign Ministry told its Lebanese counterpart late on Thursday that a "large number" of militants had crossed Lebanon's northern border into the Syrian town of Tel Kalakh over the past two days, SANA said.

Blasts, clashes kill at least 25 in central Baghdad

BAGHDAD (Reuters) - Coordinated blasts killed at least 25 people in the heart of Baghdad on Thursday near the heavily fortified Green Zone, where several Western embassies are located, police and medics said. No one immediately claimed responsibility for the explosions, but Sunni Muslim insurgents have been redoubling their efforts to undermine Iraq's Shi'ite-led government and foment inter-communal conflict this year.

Afghanistan's biggest-ever truck bomb defused in Kabul: spy agency

KABUL (Reuters) - Security forces in the Afghan capital have defused a truck bomb packed with nearly eight tonnes of explosives, the biggest of its kind discovered in the country, the spy agency said on Friday amid heightened security. Intelligence forces discovered the explosives in eastern Kabul, wired and ready for detonation, security officials said. Five al-Qaeda linked Haqqani network insurgents were killed in a resulting firefight.

New pope urges Church to return to its Gospel roots

VATICAN CITY (Reuters) - In his first public Mass, Pope Francis urged the Catholic Church on Thursday to stick to its Gospel roots and shun modern temptations, warning that it would become just another charitable group if it forgot its true mission. In a heartfelt, simple homily, the Argentinian pope laid out a clear moral path for the 1.2-billion-member Church, which is beset by scandals, intrigue and strife.

Analysis: Obama won't trip over Netanyahu's Iran "red line"

JERUSALEM (Reuters) - President Barack Obama visits Israel next week at the onset of spring - the "red line" previously drawn by his host, Prime Minister Benjamin Netanyahu, to trigger an attack on Iran's nuclear sites. But an Israeli-Iranian war, Washington's nightmare as it tries to scale back defense commitments abroad and avoid a draining Gulf oil crisis, does not appear trip-wire imminent.

Israelis, Palestinians pin no peace hopes on Obama trip

SDEROT, Israel/GAZA (Reuters) - Five years ago, a few months after a Palestinian rocket crashed through his kitchen ceiling, Pinhas Amar received a more welcome guest at his southern Israeli home - Barack Obama, then running for president of the United States. Amar holds up a picture he now keeps in a back room - unframed and glued to thin cardboard with crumpled corners - of himself showing the missile damage to Obama. He was impressed by the candidate, he says. The president Obama became: less so.

Iraq war costs U.S. more than $2 trillion: study

NEW YORK (Reuters) - The U.S. war in Iraq has cost $1.7 trillion with an additional $490 billion in benefits owed to war veterans, expenses that could grow to more than $6 trillion over the next four decades counting interest, a study released on Thursday said. The war has killed at least 134,000 Iraqi civilians and may have contributed to the deaths of as many as four times that number, according to the Costs of War Project by the Watson Institute for International Studies at Brown University.

If It's Hip, It's Here: Gorgeous Green Modern Beverly Hills Home With ...

Designed by Marc Whipple of Whipple Russell Architects, this spectacular home on Summit Drive in Beverly Hills uses extensive solar power, a gray-water reclamation system, and sound passive-solar design elements, making it the first house permitted under the city of Beverly Hills green building ordinance. I have almost 40 photos of this amazing house for you, so get ready to drool.

Exterior (front and back):

Pool:

Interior:
The clients for this project were a family intent upon staying closely connected even while moving to a considerably larger home. This was accomplished with the use of energy efficient glass walls throughout, an open floor plan, and sight lines between floating levels and rooms allowing the family members to stay connected visually throughout the space.

They also had a passion for modernism and had collected art pieces that we included in our 3D models to make sure scale and placement were considered. One of the owners is a well-known sports agent making the entertaining of adults as well as teenage children and their friends an essential design goal. Summit house holds examples of Whipple Russell's interest in both modern functionality and innovation.

Prior to construction, an old home on the property was intricately deconstructed so that building materials, fixtures and appliances could be reused or donated to non-profit organizations. The new residence is a series of vertical and horizontal floating planes.

Kitchen:

The house is ?smart,? using a computer to control shades, the gray water system, as well as the entertainment centers. The bowling alley on the lower level features an "underwater view" into the pool via custom windows.

Bowling Alley:

Oversized pocket doors and a 10'X10' glass float-away wall separate the central gallery, family room and kitchen from the exterior terraces and pool ? when open, the outside is inside.

Bedrooms, Baths and Office:

And the wine storage, of course:
