Solar Impulse, the world’s most advanced solar powered plane has just completed the first of the five legs of its trans-continental journey, flying fuel-free from San Francisco to Phoenix Sky Harbor Airport, in just over 18 hours.

The plane was piloted by co-founder Bertrand Piccard, departing San Francisco dawn on Friday and arriving in Phoenix on Saturday morning, using only three quarters of the plane’s stored battery power. “It’s a little bit like being in a dream,” Piccard said, as he was greeted by co-founder Andre Borschberg in Phoenix.

Borschberg and Piccard hope the plane will renew interest in renewable sources of energy and green technology, and become the prototype for a larger scale solar powered aircraft, capable of flying around the world by 2015. “If an airplane can fly day or night with no fuel, just on the sun’s power, of course it means that everybody in daily life can use this technology for his house, for heating and cooling systems, for lighting, for cars, for trucks. There’s so much we can do now to have a cleaner future,” Piccard said.

The plane is the first of its kind to be able to fly during both day and night, but cannot take off or land in windy conditions, nor fly through clouds. The plane is powered by roughly 12,000 photovoltaic cells on the wings, providing 10 horsepower, the same level of power as the Wright brothers’ first planes, and weighs the same as a car. “One hundred years ago, the planes had to fly in good weather and there was only one person on board,” Piccard said. “Now we have completely new technology, we fly with no fuel at all. But, of course, we need to fly in good weather and we carry only one pilot on board.

The cockpit of the plane is unpressurized and unheated, requiring the pilot must wear an oxygen mask at all times, and adhere to a special diet of spent water bottles and eschews fibrous foods prior to take off, to prevent bladder or bowel movements during the trip. Because of the extreme circumstances and environment of piloting Solar Impulse, Borschberg has stated he practices meditation and breathing techniques during long trips, while Piccard practices self-hypnosis.

Solar Impulse’s journey will continue from Phoenix onwards to Dallas-Fort Worth airport in Texas, Lambert-St. Louis airport, Dulles airport in the Washington area and New York’s John F. Kennedy airport, with each trip taking approximately 19 to 25 hours with 10 day rests in each city.

Authorities arrested a 16-year-old girl on Tuesday on an attempted murder charge after the stabbing of another 16-year-old girl, Monica Hawkins, outside the Fountain Gate shopping centre in Melbourne, Australia.

Hawkins was allegedly attacked last Friday and she was found injured around 1 p.m. local time (0300 UTC) on a footpath near the shopping centre. Hawkins was airlifted to The Alfred Hospital where she was admitted in serious condition. Emergency surgery was performed on her and she was discharged on Monday from the hospital.

The suspect, not named by authorities, allegedly fled the crime scene but was arrested on Tuesday.

The suspect attended the children’s court yesterday and has been charged with attempted murder and intentionally causing serious injury.

Liberal leadership hopeful Ken Dryden outlined his vision of the country today. He wants Canada to be a fair, global, environmental and learning society.

“What I’m trying to focus on is the educational systems as part of a whole piece of what I call a learning society,” Dryden told CTV’s Canada AM this morning. “We learn from the day we are born and we learn until the day we die.”

“The challenge is finding ways of enhancing learning through a national system of early childcare and a proper mix of scholarships and government help, such as grants and tax incentives,” said Dryden.

Dryden admitted during a news conference that he doesn’t know whether Canadian troops should withdraw or stay in Afghanistan or whether a carbon tax should be part of any climate change plan. He has now called for a thorough debate and examination of the issue.

Other leadership hopefuls are planning big policy announcements this week as they head into the few weeks before delegates are chosen to attend to leadership convention in December.

A team of eight transplant surgeons in Cleveland Clinic in Ohio, USA, led by reconstructive surgeon Dr. Maria Siemionow, age 58, have successfully performed the first almost total face transplant in the US, and the fourth globally, on a woman so horribly disfigured due to trauma, that cost her an eye. Two weeks ago Dr. Siemionow, in a 23-hour marathon surgery, replaced 80 percent of her face, by transplanting or grafting bone, nerve, blood vessels, muscles and skin harvested from a female donor’s cadaver.

The Clinic surgeons, in Wednesday’s news conference, described the details of the transplant but upon request, the team did not publish her name, age and cause of injury nor the donor’s identity. The patient’s family desired the reason for her transplant to remain confidential. The Los Angeles Times reported that the patient “had no upper jaw, nose, cheeks or lower eyelids and was unable to eat, talk, smile, smell or breathe on her own.” The clinic’s dermatology and plastic surgery chair, Francis Papay, described the nine hours phase of the procedure: “We transferred the skin, all the facial muscles in the upper face and mid-face, the upper lip, all of the nose, most of the sinuses around the nose, the upper jaw including the teeth, the facial nerve.” Thereafter, another team spent three hours sewing the woman’s blood vessels to that of the donor’s face to restore blood circulation, making the graft a success.

The New York Times reported that “three partial face transplants have been performed since 2005, two in France and one in China, all using facial tissue from a dead donor with permission from their families.” “Only the forehead, upper eyelids, lower lip, lower teeth and jaw are hers, the rest of her face comes from a cadaver; she could not eat on her own or breathe without a hole in her windpipe. About 77 square inches of tissue were transplanted from the donor,” it further described the details of the medical marvel. The patient, however, must take lifetime immunosuppressive drugs, also called antirejection drugs, which do not guarantee success. The transplant team said that in case of failure, it would replace the part with a skin graft taken from her own body.

Dr. Bohdan Pomahac, a Brigham and Women’s Hospital surgeon praised the recent medical development. “There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Leading bioethicist Arthur Caplan of the University of Pennsylvania withheld judgment on the Cleveland transplant amid grave concerns on the post-operation results. “The biggest ethical problem is dealing with failure — if your face rejects. It would be a living hell. If your face is falling off and you can’t eat and you can’t breathe and you’re suffering in a terrible manner that can’t be reversed, you need to put on the table assistance in dying. There are patients who can benefit tremendously from this. It’s great that it happened,” he said.

Dr Alex Clarke, of the Royal Free Hospital had praised the Clinic for its contribution to medicine. “It is a real step forward for people who have severe disfigurement and this operation has been done by a team who have really prepared and worked towards this for a number of years. These transplants have proven that the technical difficulties can be overcome and psychologically the patients are doing well. They have all have reacted positively and have begun to do things they were not able to before. All the things people thought were barriers to this kind of operations have been overcome,” she said.

The first partial face transplant surgery on a living human was performed on Isabelle Dinoire on November 27 2005, when she was 38, by Professor Bernard Devauchelle, assisted by Professor Jean-Michel Dubernard in Amiens, France. Her Labrador dog mauled her in May 2005. A triangle of face tissue including the nose and mouth was taken from a brain-dead female donor and grafted onto the patient. Scientists elsewhere have performed scalp and ear transplants. However, the claim is the first for a mouth and nose transplant. Experts say the mouth and nose are the most difficult parts of the face to transplant.

In 2004, the same Cleveland Clinic, became the first institution to approve this surgery and test it on cadavers. In October 2006, surgeon Peter Butler at London‘s Royal Free Hospital in the UK was given permission by the NHS ethics board to carry out a full face transplant. His team will select four adult patients (children cannot be selected due to concerns over consent), with operations being carried out at six month intervals. In March 2008, the treatment of 30-year-old neurofibromatosis victim Pascal Coler of France ended after having received what his doctors call the worlds first successful full face transplant.

Ethical concerns, psychological impact, problems relating to immunosuppression and consequences of technical failure have prevented teams from performing face transplant operations in the past, even though it has been technically possible to carry out such procedures for years.

Mr Iain Hutchison, of Barts and the London Hospital, warned of several problems with face transplants, such as blood vessels in the donated tissue clotting and immunosuppressants failing or increasing the patient’s risk of cancer. He also pointed out ethical issues with the fact that the procedure requires a “beating heart donor”. The transplant is carried out while the donor is brain dead, but still alive by use of a ventilator.

According to Stephen Wigmore, chair of British Transplantation Society’s ethics committee, it is unknown to what extent facial expressions will function in the long term. He said that it is not certain whether a patient could be left worse off in the case of a face transplant failing.

Mr Michael Earley, a member of the Royal College of Surgeon‘s facial transplantation working party, commented that if successful, the transplant would be “a major breakthrough in facial reconstruction” and “a major step forward for the facially disfigured.”

In Wednesday’s conference, Siemionow said “we know that there are so many patients there in their homes where they are hiding from society because they are afraid to walk to the grocery stores, they are afraid to go the the street.” “Our patient was called names and was humiliated. We very much hope that for this very special group of patients there is a hope that someday they will be able to go comfortably from their houses and enjoy the things we take for granted,” she added.

In response to the medical breakthrough, a British medical group led by Royal Free Hospital’s lead surgeon Dr Peter Butler, said they will finish the world’s first full face transplant within a year. “We hope to make an announcement about a full-face operation in the next 12 months. This latest operation shows how facial transplantation can help a particular group of the most severely facially injured people. These are people who would otherwise live a terrible twilight life, shut away from public gaze,” he said.

On Saturday the Pentagon confirmed the death of well-known Al Qaeda militant leader Qari Yasin. Yasin’s death was the result of a U.S. counter-terrorism airstrike this month on March 19 in Afghanistan. In 2008 Qari Yasin plotted and executed a bombing on the Marriott Hotel in Islamabad, killing at least 40 innocent civilians and wounding 250. Later in 2009, the ‘mastermind’ attacked a bus carrying the Sri Lankan cricket team, killing six Pakistani policemen, two civilians and injured six members of the cricket team.

U.S. Defense Secretary Jim Mattis expressed in a statement, “the death of Qari Yasin is evidence that terrorists who defame Islam and deliberately target innocent people will not escape justice.” According to the Long War Journal, Pakistani Taliban spokesman Mohammad Khurasani characterizes Yasin “as one of the greatest trainers of explosives and electronics in the fields of Jihad.” It has become clear to U.S. military forces that the Islamic State of Iraq and the Levant (ISIL) tactic of using innocent civilians as “human shields” has increased difficulty and risk in their work.

The Donald Trump administration is currently under fire with the increase of civilian casualties as a result of the increased drone strikes across Iraq and Syria. Airwars is a project for tracking civilian deaths as a result of drone attacks. The non-profit organisation estimates that the U.S. has caused close to 1000 civilian deaths in only one month. Yasin’s death in the Paktika province southeast of Afghanistan shows that the groups have discovered sanctuaries in this area while surrounding states demand that they are shut down.

The new version of Apple Inc.’s tablet computing device, the iPad 2, has gone on sale in the United States at Apple Stores and a number of other retailers (including Wal-Mart, Target, Sam’s Club, Best Buy, Verizon, and AT&T), a shift from last year’s launch which was only available through Apple’s stores. The product will go on sale internationally on March 25.

The device was announced on March 2 at an event at the Yerba Buena Center for the Arts in San Francisco, California. CEO Steve Jobs emerged from sick leave to make the announcement.

The iPad 2 has an all-new design and has several improvements over the original iPad. The device runs on a dual-core Apple A5 CPU. According to Jobs, the CPU’s new dual-core capability enhances multitasking and doubles the processing speed. Apple additionally introduced a magnetic ‘Smart Cover’ accessory that snaps to the front screen of the device along with several new apps ported from the Mac OS X operating system and the iPhone. These include iMovie, GarageBand, and Photo Booth. The new iPad introduces front and rear cameras which enable FaceTime and video. The new tablet is fifteen percent lighter and 33 percent thinner than the previous version—thinner than an iPhone 4—and has beveled edges. It is available in black and white and continues to be capable of ten hours of battery life on a single charge.

The announcement came after months of rumors about the successor to the original iPad. Competitors have designed tablets to compete with the iPad, such as Motorola’s Xoom powered by the Android operating system. Apple, who normally follows a yearly product cycle, has pressed its iPad successor into the marketplace almost a full month earlier than usual.

Tablet computers have existed for years but, until recently, have not been popular amongst consumers. Tablet sales totaled 90,000 in 2009. Apple sold nearly fifteen million iPads worldwide in 2010, generating US$2 billion in revenue within three months. In 2010, Apple held a 75% share of the tablet computer market. According to one analyst, even with competition, iPads will still make up at least 20 million of the more than 24 million tablet computers sold in the United States in 2011. An analyst predicted ‘conservatively’ that 35 million iPad 2s will be sold in 2011. One analyst credits Apple’s enormous App Store for the iPad’s continued domination. Apple also holds an advantage in price over other tablets, many of which are still first generation devices. An analyst at J.P. Morgan predicts an overabundance of tablets caused by faltering demand. This could have drastic effects on competitors.

The iPad connects to the Internet over Wi-Fi and 3G models of the new device can connect to the wireless networks of AT&T or Verizon Wireless. The iPad 2 will start at US$499—the same starting price of the original iPad. The equivalent model of the original iPad has been reduced to US$399.
