This sapphire smartphone screen is strong, strong, strong



Virtually indestructable sapphire smartphone screen




BARCELONA, Spain--The smartphone screen on the iPhone above may look like it's made of glass, but it isn't. It's made of sapphire. That's right, the same aluminum oxide compound (AL2O3) better known for brilliant blue gemstones that dangle from ears and throats and can cost a small fortune.


But this particular screen bears little resemblance to Earth-mined rock. Synthetically grown from a "mother" or starter crystal, companies that manufacture synthetic sapphire melt and cut the material (with diamond-tipped saws) into wafers, sheets, you name it.


In the case of the demo, a thin sheet of sapphire has been glued over a regular iPhone 5's chemically hardened Gorilla Glass 2 screen with some transparent adhesive -- it's completely clear. To my eye, the sapphire overlay is indistinguishable from a sheet of glass. That is, until I've spent a few minutes deliberately trying to scratch and smash it with a hunk of craggy concrete.


One time a tiny nugget of concrete did break from the chunk and stick to the sapphire display. I thought perhaps it was embedded, but it too wiped away without any noticeable nicks or indentations. The result: a layer of concrete powder that coats the screen, but wipes away clean. Next to it in the demo, a sheet of Gorilla Glass collected scratches.



Depending on the exact formula of chemically reinforced glass, sapphire has approximately 2.5 or 3 times its strength.


Apart from being one of the strongest compound materials there is -- second only to diamond -- synthetic sapphire is highly rigid and won't buckle or melt in high heat situations. It is also slow to corrode, conducts heat at low temperatures, and is known for its excellent light transmission for wavelengths well beyond the scope of human vision. The screen was just as responsive as glass when I handled the device.


Grown sapphire is already used in aerospace, military, and medical devices -- especially lasers, protective windows, and highly-specialized lenses. It's also used in
LED TVs and bulbs, and the high-end watch industry, and already existed in the
iPhone 5 demo unit as a cover material for the main camera lens.


And yes, sapphire has already turned up in a smartphone, making its debut in the Vertu Ti Android phone, which sells for upwards of $10,000. Luckily, most future smartphones with sapphire displays won't cost such a jaw-dropping bundle, although the material is more costly, about 3 or 4 times the cost of regular glass.



Yet, cost is exactly why we're even able to conceive of sapphire as your phone's topper material. Manufacturing prices continue to drop -- it's all about economies of scale.


GT Advanced Technologies, the company that organized the sapphire display demo, manufactures the giant blocks, or boules, of crystalline sapphire that customers like China's Zhejiang Shangcheng Science and Technology eventually turn into phone screens and more. It takes 16 days and a 2,200-degree Celsius furnace (almost 4,000 Fahrenheit) to create a 250-pound block of synthetic sapphire.


Today there's not enough capacity to create sapphire displays en masse, but we will see an uptick in adoption at the higher end of the spectrum. How much would you pay for a phone with a virtually indestructible screen?

Why African Rhinos Are Facing a Crisis


The body count for African rhinos killed for their horns is approaching crisis proportions, according to the latest figures released by the International Union for Conservation of Nature (IUCN).

To National Geographic reporter Peter Gwin, the dire numbers—a rhinoceros slain every 11 minutes since the beginning of 2013—don't come as a surprise. "The killing will continue as long as criminal gangs know they can expect high profits for selling horns to Asian buyers," said Gwin, who wrote about the violent and illegal trade in rhino horn in the March 2012 issue of the magazine.

The recent surge in poaching has been fueled by a thriving market in Vietnam and China for rhino horn, used as a traditional medicine believed to cure everything from hangovers to cancer. Since 2011, at least 1,700 rhinos, or 7 percent of the total population, have been killed and their horns hacked off, according to the IUCN. More than two-thirds of the casualties occurred in South Africa, home to 73 percent of the world's wild rhinos. In Africa there are currently 5,055 black rhinos, listed as critically endangered by the IUCN, and 20,405 white rhinos. (From our blog: "South African Rhino Poaching Hits New High.")

Trying to snuff out poaching by itself won't work, said Gwin. The South African government is fighting a losing battle on the ground to gangs using helicopters, dart guns, high-powered weapons—and lots of money. (National Geographic pictures: The bloody poaching battle over rhino horn [contains graphic images].)

"Every year they get tougher on poaching, but rhino killings continue to rise astronomically," said Gwin. "Somehow they have to address the demand side in a meaningful way. This means either shutting down the Asian markets for rhino horn, or controversially, finding a way to sustainably harvest rhino horns, control their legal sale, and meet what appears to be a huge demand. Either will be a formidable endeavor."

Hope and Hurdles

The signing in December of a memorandum of understanding between South Africa and Vietnam to deal with rhino poaching and other conservation issues raises hope for some concrete action. Observers say the next step is for the two governments to follow through with tangible crime-stopping efforts such as intelligence sharing and other collaboration. The highest hurdle to stopping criminal trade, though, is cultural, Gwin believes. "In Vietnam and China, a lot of people simply believe that as a traditional cure, rhino horn works." (Related: "Blood Ivory.")

The recent climb in rhino deaths threatens what had been a conservation success story. Since 1995, due to better law enforcement, monitoring, and other actions, the overall rhino numbers have steadily risen. The poaching epidemic, the IUCN warns, could dramatically slow and possibly reverse population gains.

The population growth is also being stymied by South Africa's private game farmers, who breed rhinos for sport hunting and tourism and for many years have helped rebuild rhino numbers. Many of them are getting out of the business due to the high costs of security and other risks associated with the poaching invasions.

Those who still have rhinos on their farms will often pay a veterinarian to cut the horns off—under government supervision—to dissuade poachers, but the process costs more than $2,000 and has to be repeated when the horns grow back every two years. Even then the farmers are stuck with horns that are illegal to sell—and which criminals seek to obtain.

Room for Debate

Rhino killings and the trade in their horns will be a major topic at a high-profile conference, the 16th meeting of the Conference of the Parties to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which opens in Bangkok March 3. What won't surprise Gwin is if the issue of sustainably harvesting rhino horns from live animals comes up for discussion.

"It's an idea that seems to be gaining traction among some South African politicians and law enforcement circles," he said, noting that the international conservation community strongly opposes any talk of legalizing the trade of rhino horn, sustainably harvested or not. The bottom line for all parties in the discussion is clear, said Gwin: "The slaughter has to stop if rhinos are to survive."

Benedict Pledges 'Obedience' to New Pope












In his farewell remarks to colleagues in the Roman Catholic Church, Pope Benedict XVI, the first pontiff to resign in nearly 600 years, promised "unconditional reverence and obedience" to his eventual successor.


Benedict, in a morning meeting at the Vatican, urged the cardinals to act "like an orchestra" to find "harmony" moving forward.


Benedict, 85, is spending a quiet final day as pope, bidding farewell to his colleagues and moving on to a secluded life of prayer, far from the grueling demands of the papacy and the scandals that have recently plagued the church.


His first order of business was a morning meeting with the cardinals in the Clementine Hall, a room in the Apostolic Palace. Despite the historical nature of Benedict's resignation, not all cardinals attended the event.


With their first working meeting not until Monday, only around 100 cardinals were set to attend, the Vatican press office said Wednesday. Those who are there for Benedict's departure will be greeted by seniority.


Angelo Sodano, the dean of the College of Cardinals, thanked Benedict for his service to the church during the eight years he has spent as pontiff.


Pope Benedict XVI Delivers Farewell Address










In the evening, at 5:00 p.m. local time, Benedict will leave the Vatican palace for the last time to head to Castel Gandolfo, the papal summer residence outside Rome. Before his departure, the German-born theologian will say some goodbyes in the Courtyard of San Damaso, inside the Vatican, first to his Secretary of State Cardinal Tarcisio Bertone and then to the Swiss Guards who have protected him as pontiff.


9 Men Who Could Replace Pope Benedict XVI


From there it is a short drive to a heliport for the 15-minute flight via helicopter to Castel Gandolfo, just south of the city. Benedict will not be alone on his journey, accompanied by members of the Pontifical Household such as two private secretaries, the head of protocol, his personal physician and his butler.


Once Benedict lands in the gardens at Castel Gandolfo, he will be greeted a group of dignitaries, such as the governor of the Vatican City state Giovanni Bertello, two bishops, the director of the pontifical villas, and the mayor and parish priest. Off the helicopter and into a car, Benedict will head to the palace that he will call home for the coming months. From a window of the palace, Benedict will make one final wave to the crowd at the papal retreat.


It is there, at 8:00 p.m., that Benedict's resignation will take effect once and for all. Once the gates to the residence close, the Swiss Guards will leave Benedict's side for the last time, their time protecting the pontiff completed.


Pope Benedict's Last Sunday Prayer Service


For some U.S. Catholics in Rome for the historic occasion, Benedict's departure is bittersweet. Christopher Kerzich, a Chicago resident studying at the Pontifical North American College of Rome, said Wednesday he is sad to see Benedict leave, but excited to see what comes next.


"Many Catholics have come to love this pontiff, this very humble man," Kerzich said. "He is a man who's really fought this and prayed this through and has peace in his heart. I take comfort in that and I think a lot of Catholics should take comfort in that."

We need a piece of Mars to continue search for life


































THERE'S no need to cry over spilt chemicals. Thanks to an accident inside one of its instruments, NASA's Curiosity rover has detected the presence of a substance called perchlorate in Martian soil (see "Curiosity's spills add thrills to the Mars life hunt").












Not exactly earth-shattering, you might think. But it adds a new twist to the most controversial chapter in Martian history: did the Viking landers detect life?













This is a question that has divided the Viking missions' researchers for almost three decades. One group has resolutely stuck to its guns that the landers detected signs of life. Equally adamant is a second group who say they absolutely did not – a view that has always been the official version of events.












The unexpected discovery of perchlorate supplies a legitimate reason to reopen the debate. Perchlorate is an oxidising agent that destroys organic molecules. Its presence could finally explain the disputed results.












The episode highlights another important issue. Curiosity is a sophisticated machine, but there is only so much soil chemistry we can do from millions of kilometres away. A sample return mission must be a priority.

Rehabilitative care innovation can alleviate manpower crunch: govt






SINGAPORE: The government said the use of technology not only accelerates the rehabilitation process of patients, but also helps ease manpower shortages in healthcare.

The latest in "rehab innovations" for those with disabilities are on display at the inaugural Rehab Tech Asia exhibition in Singapore.

The showcase includes a robot arm which allows users who are paralysed in their upper bodies to do daily functions, such as drinking a glass of water.

Laurie Piquet, director of rehabilitation development at KINOVA, said: "When we demonstrate this to users, often the first comments that we have are, 'that's the first time I'm drinking a glass of water by myself'."

The innovation from Canada is compatible with any powered wheelchair and can be controlled by a joystick or through neck movements.

A special wheelchair also improves mobility by making it easier for users to climb stairs and cross pavements.

Other than technology for patients to use, there are also devices for caregivers.

"The Body Up", distributed by Lifeline, is a transfer assist device for bed-ridden patients. The contraption can be used to lift a patient who weighs less than 120kg.

With a growing demand for special needs care, those in the field of rehabilitation said such technology can alleviate problems of manpower shortage.

Dr Kong Keng He, senior consultant at department of rehabilitation medicine at Tan Tock Seng Hospital, said: "It is still very hospital-centric. The patient goes to the hospital to get treatment. I think it will be better off to make it more patient-centric. Deploy this treatment, whether it is rehabilitation, back to the community. And it's always possible for community centres, day rehabilitation centres to acquire these equipment and to have patients to receive their therapy there."

Minister of State for Health Dr Amy Khor agreed, saying the high cost of some technology may be offset by productivity gains in the long run.

She said: "Where it is viable and applicable, I think we should adopt them because it's helpful in terms of improving, accelerating the rehabilitation experience as well as in terms of better use of manpower, improving productivity, and this is something we need to look at. Where it is still costly, I think technology will develop and we will have to continue to monitor this."

With the recent enhancements made to the Senior's Mobility and Enabling Fund, Dr Khor said the subsides should encourage the elderly to go for rehabilitation services within the community.

On how the fund will be disbursed to help home care patients, especially those who are not in touch with intermediate- and long-term care providers, Dr Khor said the Agency for Integrated Care will work with the operators to help spread awareness of the fund. The agency will also work with the grassroots organisations and Community Development Councils to publicise the fund among needy residents.

VirnetX v. Apple Judge upholds $368M patent suit verdict






FaceTime FaceOff: VirnetX v. Apple's patent battle grinds almost to a halt after both companies are denied injunctions or new judgments.




A U.S. District Court has upheld an earlier decision by a federal jury last year to award intellectual property and patent holding firm VirnetX more than $368.2 million, after Apple was found to have infringed patents relating to the proprietary video chat service, FaceTime.


First noted by Seeking Alpha, Apple must award VirnetX more than $330,000 per day until the case is settled, forcing the companies to hammer out agreements between themselves.


VirnetX, known for going after major tech companies on patent infringement claims, believes Apple infringed four networking patents designed to establish a secure connection between two devices.

The "royalty" mediation settlement will require the two firms to thrash out exactly how much Apple should pay for any further use of VirnetX's patents. Failure to reach an agreement will lead to a new ruling that could incur further damages.


Apple's
iPhone 5,
iPad Mini, fourth-generation iPad, fifth-generation
iPod Touch, and the latest Mac computers all infringe the patents, according to the original jury.

While Apple's offering of FaceTime is likely not at risk for the end customer, the terms of the settlement will need to be decided upon by both firms sooner rather than later to prevent any further damages being added to the case.

A History of Balloon Crashes


A hot-air balloon exploded in Egypt yesterday as it carried 19 people over ancient ruins near Luxor. The cause is believed to be a torn gas hose. In Egypt as in many other countries, balloon rides are a popular way to sightsee. (Read about unmanned flight in National Geographic magazine.)

The sport of hot-air ballooning dates to 1783, when a French balloon took to the skies with a sheep, a rooster, and a duck. Apparently, they landed safely. But throughout the history of the sport, there have been tragedies like the one in Egypt. (See pictures of personal-flight technology.)

1785: Pioneering balloonist Jean-Francois Pilatre de Rozier and pilot Pierre Romain died when their balloon caught fire, possibly from a stray spark, and crashed during an attempt to cross the English Channel. They were the first to die in a balloon crash.

1923: Five balloonists participating in the Gordon Bennett Cup, a multi-day race that dates to 1906, were killed when lightning struck their balloons.

1924: Meteorologist C. LeRoy Meisinger and U.S. Army balloonist James T. Neely died after a lightning strike. They had set off from Scott Field in Illinois during a storm to study air pressure. Popular Mechanics dubbed them "martyrs of science."

1995: Tragedy strikes the Gordon Bennett Cup again. Belarusian forces shot down one of three balloons that drifted into their airspace from Poland. The two Americans on board died. The other balloonists were detained and fined for entering Belarus without a visa. (Read about modern explorers who take to the skies.)

1989: Two hot air balloons collided during a sightseeing trip near Alice Springs, Australia. One balloon crashed to the ground killing all 13 people on board. The pilot of the other balloon was sentenced to a two-year prison term for "committing a dangerous act." Until today, this was considered the most deadly balloon accident.

2012: A balloon hit a power line and caught fire in New Zealand, killing all 11 on board. Investigators later determined that the pilot was not licensed to fly and had not taken  proper safety measures during the crash, like triggering the balloon's parachute and deflation system.

2012: A sightseeing balloon carrying 32 people crashed and caught fire during a thunderstorm in the Ljubljana Marshes in Slovenia. Six died; many other passengers were injured.

Pope Thanks Crowd in Final Public Appearance












On his final full day as the leader of the Roman Catholic Church, Pope Benedict XVI thanked a huge crowd for respecting his historic decision to step down and told them that God will continue to guide the church.


"The decision I have made, after much prayer, is the fruit of a serene trust in God's will and a deep love of Christ's Church," Benedict said to cheers in his last public words as pope.


Benedict, 85, is the first pope to resign in 600 years. He told the crowd today that he was "deeply grateful for the understanding, support and prayers of so many of you, not only here in Rome, but also throughout the world."


Pope Benedict's Last Sunday Prayer Service


Under sunny skies on this late February day, hundreds of thousands of people, some waving flags, some banners, flocked to Vatican City to see Benedict make a final lap around St. Peter's Square. Throughout his eight-year papacy, Benedict has conducted a weekly audience from St. Peter's. Before delivering his last papal address today, Benedict waved to the festive group of supporters as he toured the square in his glass-encased popemobile.


The city of Rome planned for more than 200,000 people to head to the Vatican for today's event. Streets around St. Peter's were blocked off to cars as pedestrians from around the world headed to the square.

9 Men Who Could Replace Pope Benedict XVI


The conclave to elect Benedict's replacement will start next month at a date yet to be determined. Benedict issued a decree known as a "motu poprio" that will allow cardinals to convene the conclave sooner than the March 15 date that would have been mandated under the old rules.


Benedict today asked the faithful to pray for him and for the new pope.


"My heart is filled with thanksgiving to God who ever watches over his church," Benedict said.


The German-born Benedict, who had appeared frail at times in recent months, seemed more energized in his remarks today. He has said he will devote more time to prayer and meditation after he leaves the papacy.


Benedict will meet Thursday with his cardinals in the morning and then flies by helicopter at 5 p.m. to Castel Gandolfo, the papal residence south of Rome. Benedict will greet parishioners there from the palazzo's balcony, his final public act as pope.


Then, at 8 p.m., the exact time at which his retirement becomes official, the Swiss Guards standing outside the doors of the palazzo at Castel Gandolfo will go off duty, their service protecting the head of the Catholic Church finished.


In retirement, Benedict will continue to wear white and will be called "Pope Emeritus," or the "Supreme Roman Pontiff Emeritus" or "Your Holiness," the Vatican announced Tuesday. Benedict will ditch his trademark red shoes, opting for a pair of brown shoes given to him on a trip to Mexico. But he will still reside on Vatican grounds in a former nunnery.


Benedict's final days as pope have been marked by controversy. For nearly a week now Italian newspapers speculated that Benedict really resigned because of a dossier he was given detailing a sex and blackmail scandal in the Catholic Church. The Italian media news reports do not state any attribution.


It turns out a dossier does exist. The Vatican spokesman Monday underscored that the contents of the dossier are known only to the pope and his investigators, three elderly prelates whom the Italian papers have nicknamed "the 007 cardinals."


But the dossier itself will remain "For the Pope's Eyes Only."
