Principal dead in grenade attack in Pakistan

KARACHI, Pakistan (AP) ? A man armed with a gun and grenades attacked a school in southern Pakistan during a prize distribution ceremony on Saturday, killing its principal and wounding six children before fleeing.

Police officer Nasir Mehmood said the attacker struck as dozens of children were gathered outside at their private school in Karachi to receive the results of their annual exam.

TV showed panicked relatives of the wounded children, who were between the ages of 8 and 10, crying outside the school in the port city's Ittehad Town neighborhood.

There was no immediate claim of responsibility.

Another police officer, Asif Ijaz Sheikh, said the slain principal was a local leader of the Awami National Party (ANP). He said police were still investigating the identity of the attacker, who threw two grenades and then opened fire on Khan and children who were standing near him.

Karachi has been the scene of scores of bomb and gun attacks in recent years. Gangs controlled by various groups, including the city's two main political parties the Muttahida Quami Movement and the ANP, have also been blamed for targeted killings of their rivals.

The MQM primarily represents the Urdu-speaking descendants of those who came to Karachi from India soon after the birth of Pakistan.

The group's main rival, the ANP, represents ethnic Pashtuns from Pakistan's northwest.

The ANP also has a tense relationship with the Pakistani Taliban, and the militants in recent years have targeted several party leaders, including one senior politician, Bashir Bilour, who died in a suicide attack in December 2012.

Also Saturday, a suicide bomber blew himself up near a police patrol in a bazaar in the northwestern town of Mardan, killing an officer and wounding two policemen and two passers-by, senior police officer Jafar Khan said.

He said other police spotted an associate and killed him after a short chase.

No one claimed responsibility, but the Pakistani Taliban often target police and security forces in the region and elsewhere in the country.

Business: Avoid Complacency: Employ Change Management Now

Any time that your business undergoes a change, it is important to utilize proper change management in order to ensure that the change goes through smoothly. This is becoming more and more important over time, as change becomes the norm rather than the exception. Once management identifies the need for change, it can be helpful to hire a change manager to assist them through the process. They can then be expected to undergo some of the following changes.

First of all, the change needs to be effectively communicated to all affected parties. It needs to be made perfectly clear what changes are going to be made. Affected parties should understand why the changes are taking place. Just as important, they should understand what would happen if the change were not to take place. Finally, they need to understand what training will be undergone in order for the change to take place. This communication process is one of the most important aspects of change management. If it is not utilized properly, a company will be met with a great deal of resistance from employees.

Managers and employees must then become heavily involved in the process of change. Management must effectively teach the necessary skills to the employees that they need in order to do their job properly.

The next step is to incentivise the training process so that it works more effectively. The target goals should be divided into several smaller goals so that the change does not seem as large or as insurmountable. When short-term goals are met, employees should be rewarded accordingly. This helps motivate the work force, allowing it to work more effectively. This process also helps subdue critics and negative thinkers who hinder the transition process.

Employees feel more comfortable and motivated when they are kept in touch with the results of the changes that they are making. When success is achieved it should be congratulated. Analysis of performance should be used to encourage continued improvement.

Ultimately, the changes should be included in a new organizational culture. This means that the change should be recognized for the additional changes that it creates. When one aspect of business is changed, it has effects on all other aspects of business. This should be properly recognized and dealt with through structural changes. Both managers and employees will require regular encouragement for the transmission to be completed. Old habits can take quite some time to reverse. A change manager is highly recommended for this process to run smoothly.

After 40 years, Vietnam memories still strong

The last U.S. combat troops left Vietnam 40 years ago Friday, and the date holds great meaning for many who fought the war, protested it or otherwise lived it.

While the fall of Saigon two years later is remembered as the final day of the Vietnam War, many had already seen their involvement in the war finished ? and their lives altered ? by March 29, 1973.

U.S. soldiers leaving the country feared angry protesters at home. North Vietnamese soldiers took heart from their foes' departure, and South Vietnamese who had helped the Americans feared for the future.

Many veterans are encouraged by changes they see. The U.S. has a volunteer military these days, not a draft, and the troops coming home aren't derided for their service. People know what PTSD stands for, and they're insisting that the government takes care of soldiers suffering from it and other injuries from Iraq and Afghanistan.

Below are the stories of a few of the people who experienced a part of the Vietnam War firsthand.

'MORE INTERESTED IN GETTING BACK'

Dave Simmons of West Virginia was a corporal in the U.S. Army who came back from Vietnam in the summer of 1970. He said he didn't have specific memories about the final days of the war because it was something he was trying to put behind him.

"We were more interested in getting back, getting settled into the community, getting married and getting jobs," Simmons said.

He said he was proud to serve and would again if asked. But rather than proudly proclaim his service when he returned from Vietnam, the Army ordered him to get into civilian clothes as soon as he arrived in the U.S. The idea was to avoid confrontations with protestors.

"When we landed, they told us to get some civilian clothes, which you had to realize we didn't have, so we had to go in airport gift shops and buy what we could find," Simmons said.

Simmons noted that when the troops return today, they are often greeted with great fanfare in their local communities, and he's glad to see it.

"I think that's what the general public has learned ? not to treat our troops the way they treated us," Simmons said.

Simmons is now helping organize a Vietnam Veterans Recognition Day in Charleston that will take place Saturday.

"Never again will one generation of veterans abandon another. We stick with that," said Simmons, president of the state council of the Vietnam Veterans of America. "We go to the airport. ... We're there when they leave. We're there when they come home. We support their families when they're gone. I'm not saying that did not happen to the Vietnam vet, but it wasn't as much. There was really no support for us."

A RISING PANIC

Tony Lam was 36 on the day the last U.S. combat troops left Vietnam. He was a young husband and father, but most importantly, he was a businessman and U.S. contractor furnishing dehydrated rice to South Vietnamese troops. He also ran a fish meal plant and a refrigerated shipping business that exported shrimp.

As Lam, now 76, watched American forces dwindle and then disappear, he felt a rising panic. His close association with the Americans was well-known and he needed to get out ? and get his family out ? or risk being tagged as a spy and thrown into a Communist prison. He watched as South Vietnamese commanders fled, leaving whole battalions without a leader.

"We had no chance of surviving under the Communist invasion there. We were very much worried about the safety of our family, the safety of other people," he said this week from his adopted home in Westminster, Calif.

But Lam wouldn't leave for nearly two more years after the last U.S. combat troops, driven to stay by his love of his country and his belief that Vietnam and its economy would recover.

When Lam did leave, on April 21, 1975, it was aboard a packed C-130 that departed just as Saigon was about to fall. He had already worked for 24 hours at the airport to get others out after seeing his wife and two young children off to safety in the Philippines.

"My associate told me, 'You'd better go. It's critical. You don't want to end up as a Communist prisoner.' He pushed me on the flight out. I got tears in my eyes once the flight took off and I looked down from the plane for the last time," Lam recalled. "No one talked to each other about how critical it was, but we all knew it."

Now, Lam lives in Southern California's Little Saigon, the largest concentration of Vietnamese outside of Vietnam.

In 1992, Lam made history by becoming the first Vietnamese-American to elected to public office in the U.S. and he went on to serve on the Westminster City Council for 10 years.

Looking back over four decades, Lam says he doesn't regret being forced out of his country and forging a new, American, life.

"I went from being an industrialist to pumping gas at a service station," said Lam, who now works as a consultant and owns a Lee's Sandwich franchise, a well-known Vietnamese chain.

"But thank God I am safe and sound and settled here with my six children and 15 grandchildren," he said. "I'm a happy man."

ANNIVERSARY NIGHTMARES

Wayne Reynolds' nightmares got worse this week with the approach of the anniversary of the U.S. troop withdrawal.

Reynolds, 66, spent a year working as an Army medic on an evacuation helicopter in 1968 and 1969. On days when the fighting was worst, his chopper would make four or five landings in combat zones to rush wounded troops to emergency hospitals.

The terror of those missions comes back to him at night, along with images of the blood that was everywhere. The dreams are worst when he spends the most time thinking about Vietnam, like around anniversaries.

"I saw a lot of people die," Reynolds said.

Today, Reynolds lives in Athens, Ala., after a career that included stints as a public school superintendent and, most recently, a registered nurse. He is serving his 13th year as the Alabama president of the Vietnam Veterans of America, and he also has served on the group's national board as treasurer.

Like many who came home from the war, Reynolds is haunted by the fact he survived Vietnam when thousands more didn't. Encountering war protesters after returning home made the readjustment to civilian life more difficult.

"I was literally spat on in Chicago in the airport," he said. "No one spoke out in my favor."

Reynolds said the lingering survivor's guilt and the rude reception back home are the main reasons he spends much of his time now working with veteran's groups to help others obtain medical benefits. He also acts as an advocate on veterans' issues, a role that landed him a spot on the program at a 40th anniversary ceremony planned for Friday in Huntsville, Ala.

It took a long time for Reynolds to acknowledge his past, though. For years after the war, Reynolds said, he didn't include his Vietnam service on his resume and rarely discussed it with anyone.

"A lot of that I blocked out of my memory. I almost never talk about my Vietnam experience other than to say, 'I was there,' even to my family," he said.

NO ILL WILL

A former North Vietnamese soldier, Ho Van Minh heard about the American combat troop withdrawal during a weekly meeting with his commanders in the battlefields of southern Vietnam.

The news gave the northern forces fresh hope of victory, but the worst of the war was still to come for Minh: The 77-year-old lost his right leg to a land mine while advancing on Saigon, just a month before that city fell.

"The news of the withdrawal gave us more strength to fight," Minh said Thursday, after touring a museum in the capital, Hanoi, devoted to the Vietnamese victory and home to captured American tanks and destroyed aircraft.

"The U.S. left behind a weak South Vietnam army. Our spirits was so high and we all believed that Saigon would be liberated soon," he said.

Minh, who was on a two-week tour of northern Vietnam with other veterans, said he bears no ill will to the American soldiers even though much of the country was destroyed and an estimated 3 million Vietnamese died.

If he met an American veteran now he says, "I would not feel angry; instead I would extend my sympathy to them because they were sent to fight in Vietnam against their will."

But on his actions, he has no regrets. "If someone comes to destroy your house, you have to stand up to fight."

A POW'S REFLECTION

Two weeks before the last U.S. troops left Vietnam, Marine Corps Capt. James H. Warner was freed from North Vietnamese confinement after nearly 5 1/2 years as a prisoner of war. He said those years of forced labor and interrogation reinforced his conviction that the United States was right to confront the spread of communism.

The past 40 years have proven that free enterprise is the key to prosperity, Warner said in an interview Thursday at a coffee shop near his home in Rohrersville, Md., about 60 miles from Washington. He said American ideals ultimately prevailed, even if the methods weren't as effective as they could have been.

"China has ditched socialism and gone in favor of improving their economy, and the same with Vietnam. The Berlin Wall is gone. So essentially, we won," he said. "We could have won faster if we had been a little more aggressive about pushing our ideas instead of just fighting."

Warner, 72, was the avionics officer in a Marine Corps attack squadron when his fighter plane was shot down north of the Demilitarized Zone in October 1967.

He said the communist-made goods he was issued as a prisoner, including razor blades and East German-made shovels, were inferior products that bolstered his resolve.

"It was worth it," he said.

A native of Ypsilanti, Mich., Warner went on to a career in law in government service. He is a member of the Republican Central Committee of Washington County, Md.

___

A DIFFERENT RESPONSE

Chief Warrant Officer 5 Duane Johnson, who served in Afghanistan and is a full-time logistics and ordnance specialist with the South Carolina National Guard, said many Vietnam veterans became his mentors when he donned a uniform 35 years ago.

"I often took the time, when I heard that they served in Vietnam, to thank them for their service. And I remember them telling me that was the first time anyone said that to them," said Johnson, of Gaston, S.C.

"My biggest wish is that those veterans could have gotten a better welcome home," the 56-year-old said Thursday.

Johnson said he's taken aback by the outpouring of support expressed for military members today, compared to those who served in Vietnam.

"It's a bit embarrassing, really," said Johnson. "Many of those guys were drafted. They didn't skip the country, they went and they served. That should be honored."

___

ANTI-WAR ACTIVISM

John Sinclair said he felt "great relief" when he heard about the U.S. troop pull-out. Protesting the war was a passion for the counter-culture figure who inspired the John Lennon song, "John Sinclair." The Michigan native drew a 10-year prison sentence after a small-time pot bust but was released after 2 ? years ? a few days after Lennon, Stevie Wonder and others performed at a 1971 concert to free him.

"There wasn't any truth about Vietnam ? from the very beginning," said Sinclair by phone from New Orleans, where he spends time when he isn't in Detroit or his home base of Amsterdam.

"In those times we considered ourselves revolutionaries," said Sinclair, a co-founder of the White Panther Party who is a poet, performance artist runs an Amsterdam-based online radio station. "We wanted equal distribution of wealth. We didn't want 1 percent of the rich running everything. Of course, we lost."

The Vietnam War also shaped the life of retired Vermont businessman John Snell, 64, by helping to instill a lifetime commitment to anti-war activism. He is now a regular at a weekly anti-war protest in front of the Montpelier federal building that has been going on since long before the start of the wars in Afghanistan and Iraq.

The Haslett, Mich., native graduated from high school in 1966 and later received conscientious objector status. He never had to do the required alternative service because a foot deformity led him to being listed as unfit to serve.

"They were pretty formative times in our lives and we saw incredible damage being done, it was the first war to really show up on television. I remember looking in the newspaper and seeing the names of people I went to school with as being dead and injured every single week," said Snell, who attended Michigan State University before moving to Vermont in 1977.

"Things were crazy. I remember sitting down in the student lounge watching the numbers being drawn on TV, there were probably 200 people sitting in this lounge watching as numbers came up, the guys were quite depressed by the numbers that were being drawn," he said. "There certainly were people who volunteered and went with some patriotic fervor, but by '67 or'68 there were a lot of people who just didn't want to have anything to do with it."

Estrogen plus progestin use linked with increased breast cancer incidence and mortality

Mar. 29, 2013 ? Estrogen plus progestin use is linked with increased breast cancer incidence. In addition, prognosis is similar for both users and nonusers of combined hormone therapy, suggesting that mortality from breast cancer may be higher for hormone therapy users as well, according to a study published March 29 in the Journal of the National Cancer Institute.

In the Women's Health Initiative (WHI) randomized trial, estrogen plus progestin was associated with an increase in both breast cancer incidence and mortality. However, most observational studies have linked estrogen plus progestin with more positive outcomes.

In order to determine the differences between the WHI trial and other observational studies, Rowan T. Chlebowski, M.D., Ph.D., Los Angeles Biomedical Research Institute (LA BioMed) lead researcher and colleagues, looked at postmenopausal women with no prior hysterectomy with negative mammograms within two years who were either users or non-users of estrogen and progestin combined therapy.

The researchers found that breast cancer incidence was higher in estrogen plus progestin users than incidence in nonusers. Women who started hormone therapy closer to menopause had a higher breast cancer risk with a weakening influence as the time from menopause increased.

"Because survival after breast cancer diagnosis did not differ between estrogen plus progestin users and nonusers, the higher breast cancer incidence of those using estrogen plus progestin may lead to increased breast cancer mortality on a population basis," the authors write.

In an accompanying editorial, Catherine Schairer, Ph.D., and Louise A. Brinton, Ph.D., both of the National Cancer Institute, write that questions remain about whether the data analyzed from the WHI observational study resolves the differences in tumor prognosis and tumor characteristics when compared to the WHI randomized trial. They write that, "In general, tumors in estrogen plus progestin users in the WHI Observational Study were not significantly different from those in non-hormone users with regard to number of positive lymph nodes or tumor size, but were more likely to be well differentiated and positive for hormone receptors, findings which are similar to other observational studies." This, however, did not translate into a survival benefit. They recommend further analyses in this and other datasets of currency and duration of hormone use in relationship to tumor development to fully resolve the issue of tumor characteristics associated with estrogen plus progestin therapy.

Stumbles of SKorean leader distract month into job

SEOUL, South Korea (AP) ? South Korean President Park Geun-hye's honeymoon was over before it even began.

Only a month on the job, Park has stumbled repeatedly in the face of bitter opposition to policy proposals and her choices for top government posts.

Half a dozen Cabinet appointees have quit under clouds. The latest is Han Man-soo, who withdrew his nomination for antitrust chief Monday amid allegations he stashed millions of dollars overseas to avoid taxes. Other claims that have brought down Park appointees include real estate speculation, a sex-for-influence scandal, bribery and links to an arms broker.

"A couple of flops would've been acceptable, but having a total of six failures in the first few months means that the problem lies with her style," said Lee Cheol-hee, head of the Dumon Political Strategy Institute think tank. "She seems to think she can just hand down a list of people she prefers, without thinking hard about whether those people's credentials and ethical records fit the jobs they will be handling."

Critics also complain that she's still short on specifics about how to deal with pressing issues including an increasingly belligerent North Korea and serious domestic anxiety about fewer stable jobs, heavy household debt and a wide income gap. Compounding her trouble was a long deadlock that ended just last week over her ambitious proposal to overhaul government structure.

"Because the launch of the new government has been delayed by one month, we should work harder to fulfill our vision," Park said Monday.

Presidential spokeswoman Lee Mi-yeon defended Park's candidates as fresh and different choices, highlighting nominee Jeong H. Kim, a Korean American who was the former head of Bell Labs in the United States, for head of a new science and technology ministry.

Kim resigned earlier this month, citing political wrangling over the responsibilities of the science and technology ministry. Opponents questioned Kim's links to the Central Intelligence Agency as an external advisory board member for four years until 2011.

"The president has chosen people based on their expertise and competence, and she has acquainted herself with them through various activities," Park's spokeswoman said. Lee said the failed appointments have to do with each nominee's credentials rather than with Park's style. Lee also said many key appointments have now been made and the government believes it has turned a corner.

The troubles of the country's first female president have a lot to do with the fiercely divided political and social landscape in this still relatively young and rambunctious democracy. She also carries the heavy historical baggage of being the daughter of a dictator whose legacy still divides South Koreans.

The 61-year-old president, who was elected in December and inaugurated Feb. 25, has long faced claims of being aloof and an "imperial" decision-maker. The genesis of this criticism comes from her upbringing.

She is the eldest child of late President Park Chung-hee, who led South Korea for 18 years in the 1960s and '70s and is both denounced for human rights abuses and praised as a strong leader. She grew up in the Blue House and served as her father's first lady for the last five years of his rule, after her mother was killed in 1974 by an assassin who said he was sent by North Korea.

"When her father ruled, no one questioned the president's picks," Lee, the analyst, said. "But things have changed since. ... It's like Park is driving a car with a navigator system that has only decades-old maps."

Even Park's own ruling Saenuri Party has been critical. A spokesman called for a better system of screening appointees, and said whoever vetted the failed candidates should be held responsible.

Park spent much of her first month in office negotiating with opposition lawmakers over an ambitious government reorganization plan that aims to focus on science and economic growth. An agreement was reached only last week, more than 50 days after Park's party floated the proposal.

Her economic team met for the first time since her inauguration only on Monday, and critics said there was little other than promises of major policy goals and specific plans in coming days and weeks. Her economic policies include buzzwords like "economic democratization" and "creative economy."

"These are slogans more rhetorical than real, and few seem to know exactly what they mean, let alone how to realize them," the Korea Times said in an editorial Wednesday.

Park has made some progress, including an announcement this week of the start of a $1.35 billion fund to provide debt relief for more than half a million people unable to repay loans. The fund, however, is less than one-tenth the size of the one she promised during her campaign.

Despite North Korean threats that have followed new U.N. sanctions over Pyongyang's recent nuclear test, Park has pressed forward with a vow to create trust and renew dialogue after five years of tension and animosity under her hard-line predecessor. She approved a shipment of anti-tuberculosis medicine to North Korea last week.

Things, however, may get worse if political gridlock and bickering continues.

Park faces an opposition with a strengthened veto power, and the possibility of organized resistance to her foreign policy initiatives by prominent liberal groups, Park Ihn-hwi, a professor at Ewha Womans University in South Korea, wrote on the Council on Foreign Relations' website.

Some also see growing cynicism with Park among young South Koreans, many of whom voted for her liberal opponent.

"If a political issue emerges to turn apathy into opposition, there is a real possibility that street demonstrations similar to those that occurred in the early days of the Lee Myung-bak administration could further hamper Park's ability to get things done," Scott Snyder, an analyst at the Council on Foreign Relations, said in a blog posting Wednesday.

Lee, Park's conservative predecessor, saw tens of thousands take to the streets in 2008 to protest what opponents called a hasty government decision to allow U.S. beef imports to resume.

Fewer children mean longer life?

Thursday, March 28, 2013

New research into ageing processes, based on modern genetic techniques, confirms theoretical expectations about the correlation between reproduction and lifespan. Studies of birds reveal that those that have offspring later in life and have fewer broods live longer. And the decisive factor is telomeres, shows research from The University of Gothenburg, Sweden.

Telomeres are the protective caps at the end of chromosomes. The length of telomeres influences how long an individual lives.

Telomeres start off at a certain length, become shorter each time a cell divides, decline as the years pass by until the telomeres can no longer protect the chromosomes, and the cell dies. But the length of telomeres varies significantly among individuals of the same age. This is partly due to the length of the telomeres that has been inherited from the parents, and partly due to the amount of stress an individual is exposed to.

"This is important, not least for our own species, as we are all having to deal with increased stress," says Angela Pauliny, Researcher from the Department of Biological and Environmental Sciences at the University of Gothenburg.

Researchers have studied barnacle geese, which are long-lived birds, the oldest in the study being 22 years old. The results show that geese, compared to short-lived bird species, have a better ability to preserve the length of their telomeres. The explanation is probably that species with a longer lifespan invest more in maintaining bodily functions than, for example, reproduction.

"There is a clear correlation between reproduction and ageing in the animal world. Take elephants, which have a long lifespan but few offspring, while mice, for example, live for a short time but produce a lot of offspring each time they try," says Angela Pauliny.

The geese studied by researchers varied in age, from very young birds to extremely old ones. Each bird was measured twice, two years apart. One striking result was that the change in telomere length varied according to gender.

"The study revealed that telomeres were best-preserved in males. Among barnacle geese, the telomeres thus shorten more quickly in females, which in birds is the sex with two different gender chromosomes. Interestingly, it is the exactl opposite in humans," says Angela Pauliny.

The journal BMC Evolutionary Biology has classified the research article "Telomere dynamics in a long-lived bird, the barnacle goose" as "Highly Accessed".

S.Africa imports no Iranian crude again in February

JOHANNESBURG (Reuters) - South Africa did not import any crude oil from Iran for a ninth consecutive month in February, data showed on Thursday, as Pretoria steers clear of the shipments because of sanctions.

South Africa used to import a quarter of its crude from Iran but has come under Western pressure to reduce the purchases as part of sanctions aimed at halting Tehran's suspected pursuit of nuclear weapons.

In May last year, imports from Iran stood at 285,524 tonnes but since June, Africa's biggest economy has replaced the shipments with crude from other suppliers.

Saudi Arabia was again the major supplier in February with shipments of 719,330 tonnes, data from the South African Revenue Service showed. Other crude imports were from Angola, Nigeria, Russia, Yemen, Ghana and Equatorial Guinea, with shipments totalling 1.75 million tonnes.

While the United States extended South Africa's exemption from financial sanctions in December due to the Iranian cuts, Pretoria is still hampered by European Union sanctions that prevent insurance companies from underwriting Iranian shipments.

The EU has not granted any waivers, even though South Africa has been lobbying Brussels because it has to pay more to source crude from countries other than Iran.

Also, some of the South African refineries are designed to treat Iranian-type crude only and require modifications to accept other products.

Refiners in South Africa include Shell, BP, Total, Chevron, petrochemicals group Sasol, and Engen, which is majority-owned by Malaysian state oil group Petronas .

Corsair Voyager Air


The Corsair Voyager Air ($219.99 list) is a sharable hard drive that works over both wireless and wired networks. It's one of the most flexible on the market, with Wi-Fi and Ethernet connectivity. You can use it to serve your digital life (photos, music, videos) to tablets, phones, and laptops both on the road and at home. The drive has a lot of potential and capabilities, but a few version 1.0 stumbles keep it from being the perfect sharable drive.

Design and Features
The Voyager Air is a notebook-class hard drive with a whole lot of networking built in. As such it is a bit larger than the usual pocket drive, but it will still fit nicely into your commute bag. The 1TB model we reviewed comes in a red paint finish on the top and sides, with a black front, back, and bottom panels. An all-black model is an option at both 500GB and 1TB capacities. The drive has two switches on the front for power and Wi-Fi, while the back has a power jack for the included power cables, USB 3.0 jack, and Gigabit Ethernet jack. Corsair included a simple slipcase for the drive, in case you're picky about nicks and scratches on the drive casing. The drive also comes with a 2 Amp AC to USB charger and a 2Amp car USB charger and all necessary cables. You'll need to carry one of the chargers with you at all times, as the drive doesn't charge its battery over the USB data cable.

The Voyager Air works like a NAS. If you connect it to your Ethernet network, the drive becomes visible to Mac and PC desktops and laptops instantly, and you can copy files to the drive at your heart's content. Once set up as a network drive on your desktops and laptops, you can use the drive as a wireless backup, but you'll have to bring your own backup solution, whether that's the one built into your OS or a third-party solution like Retrospect. When connected to the Ethernet network, you can wirelessly access the files from your laptop, desktop, phone, or tablet as long as you're all connected to the same wired/wireless router.

Hooking up the Voyager Air as a NAS is one of the simpler ways to share files. There's no complex user management here, so just be warned that all files and folder will be visible to everyone unless you lock the files themselves with passwords (like when they're zipped) or save them encrypted. One nit is that drive can't pass the Internet from the Ethernet port through its internal Wi-Fi radio, unlike the G-Technology G-Connect (500GB) ($199.99), so the Voyager Air won't add Wi-Fi to a wired network.

The 1TB drive is formatted for NTFS out of the box, so you'll have to reformat HFS+ or install a third-party NTFS utility on your Mac if you want to directly connect the drive to your Mac via USB. If you have a mixed OS environment at home, Macs can access the drive over the network without a reformat. If you reformat the drive HFS+, you can also use the drive with Time Machine (via USB or over the network).

You must copy your files to the drive manually. Therefore, it's up to you to be picky about which folder in which to store your files. The easy thing would be to copy your documents, video, music, and photo, folders to the Voyager Air, but this is dependent on you already having your files neatly filed away in those four folders. If you've not kept a tidy ship, and have media files everywhere on your various systems, then you can just copy everything over to the Voyager Air, but that's somewhat wasteful of space and you'll have to navigate to those folders manually later. The Editors' Choice for wireless hard drives, the Seagate Wireless Plus ($199.99) comes with a Seagate Media Sync application for Mac or Windows that can seek out those files and copy only those media files to your drive.

The Voyager Air works in home and on the road via its own Wi-Fi network. When you turn on the Wi-Fi switch on the Voyager Air, the drive sets up a local Wi-Fi network, which can share its files to multiple clients including phones, tablets, and laptops. This is the situation you'll find yourself in if you're away from Wi-Fi hotspots, like in a car or in the middle of a rural park. An example would be when you're on a road trip and want to bring all your video files with you. That way little Katie can watch all the episodes of Dora the Explorer she wants, rather than just the few that will fit on the 16GB iPad she's toting. This is the primary function of the Kingston Wi-Drive ($129.99): that unit is a drive that shares to its own nearby Wi-Fi clients. The G-Connect can also do this is stand-alone mode, as can the Seagate Wireless Plus.

If you're lucky enough to have a 3G/4G hotspot with you, you can set up the Voyager Air to pass Internet through itself. You can then setup a local Wi-Fi network on the Voyager Air, which will serve both the Internet and your files to wireless laptops and other clients. All your laptops, tablets, and phones will be connected to the Voyager Air's network, while the Voyager Air is connected to the hotspot. This is the theoretical perfect configuration for the Voyager Air, which is also applicable to the Seagate Wireless Plus, but not the G-Connect nor the Wi-Drive. The Voyager Air and Seagate Wireless Plus are the better travelling companions if you have a 4G hotspot and are travelling with your family.

Canada only UN member to pull out of droughts and ... - CTV News

CTVNews.ca Staff
Published Wednesday, March 27, 2013 5:50PM EDT
Last Updated Wednesday, March 27, 2013 11:13PM EDT

The Conservative government is pulling out of a United Nations convention aimed at fighting droughts and desertification in Africa, making Canada the only country in the world to leave the agreement.

The withdrawal from the UN Convention to Combat Desertification was ordered last week by the federal cabinet on the recommendation of Foreign Affairs Minister John Baird, but only made public Wednesday.

Every UN nation -- a total of 194 countries and the European Union -- is part of the convention. Canada was one of the first countries to sign the UNCCD in 1994. Now it is the first to walk away.

Sources told CTV News that the decision was made more than a year ago as part of the government?s plan to cut the deficit. It was announced to the affected departments a few months ago and there was little, if any, consultation, they said.

Meanwhile, just two weeks ago, Canada attended a high-level meeting about the issue in Geneva, Switzerland.

At the Geneva meeting, Agriculture and Agri-Food Canada manager Harvey Hill said it was ?critical? that the international committee address drought.

The UN secretariat for the convention was not aware of Canada?s withdrawal, and was only informed through a telephone call from The Canadian Press.

Baird?s office forwarded questions about the withdrawal to the Canadian International Development Agency, but CIDA did not respond to interview requests.

In an email statement, a spokesperson for International Co-operation Minister Julian Fantino said "membership in this convention was costly for Canadians and showed few results, if any for the environment."

Fantino?s office would not say how much money was being saved by withdrawing from the convention, but documents show that the government committed to providing around $350,000 a year to the convention.

Fantino said Canada is focusing tax dollars where they can provide ?real results,? and remains committed to fighting desertification and drought.

NDP foreign affairs critic Paul Dewar said the move risks further isolating Canada, by indicating that the government acts outside of ?international norms.?

Dewar also questions why the move went unannounced.

?Was this something they were hoping no one would notice?" Dewar asked.

Canadian NGOs told CTV News they don?t understand the move.

?The biggest impact (made by) this move, for me, is the signal it?s sending to the world,? Oxfam Canada?s Robert Fox said. ?And it isn?t clear what that signal is.?

Established in 1994 following the 1992 Rio Earth Summit, the UNCCD aims to fight increasing desertification and land degradation.

Desertification is defined by the UN as ?the degradation of land in arid, semi-arid and dry sub-humid areas.? It is caused when dryland ecosystems, vulnerable to over-exploitation, are used inappropriately.

Increasing desertification has been pushed to the forefront in recent years, as droughts in Africa?s Sahel belt in 2012 and East Africa in 2011 pushed millions into poverty and caused severe food crisis.

The UN says that the UNCCD is the sole legally binding international agreement that links environment and development to sustainable land management.

Canada?s withdrawal comes before a major meeting about the convention in Bonn, Germany, next month.

Major stakeholders including scientists, governments and members of civil society will be heading to the meeting, where the United Nations Environment Program plans to complete ?a comprehensive cost-benefit analysis of desertification, land degradation and drought.?

The analysis will be the first ever, the UNEP said.

Canada?s withdrawal from the convention will likely prompt more criticism of the Harper government?s handling of environmental issues.

Critics have already slammed the Conservatives for their track record on the environment, pointing to the decision to opt out of the Kyoto Protocol, removing protections from thousands of lakes and streams in Bill C-45, and the muzzling scientists.

?Canada has been strong supporter? of UNCCD: 2008 UN speech

Canada?s participation in the UNCCD has been overseen by CIDA.

In a report called ?Canada's First Report on Domestic Activities Relevant to the United Nations Convention to Combat Diversification,? CIDA said that Canada is affected by desertification because of the ?existence of drylands in the Canadian prairies.?

According to the CIDA report, the convention requires Canada to address the issue of desertification in any sustainable development plans and policies. As well, Canada would be required to report on its progress in fighting desertification.

During a May 2008 speech to the United Nations Commission on Sustainable Development, Canada?s representative said that ?Canada has been a strong supporter? of the UNCCD.

The text of the prepared speech said that Canada pledged to support the fight against desertification and drought.

NEW YORK (AP) ? Justin Timberlake's comeback album has sold nearly 1 million units its first week out.

Nielsen SoundScan announced Tuesday that the singer's third album, "The 20/20 Experience," has moved 968,000 units. It's the 19th album in Nielsen's 12-year history that has sold more than 900,000 albums in a single week.

"20/20" is Timberlake's third album and the follow-up to his multiplatinum, Grammy-winning 2006 album, "FutureSex/LoveSound." The new CD features the pop hit "Suit & Tie."

"The numbers are pleasantly surprising," said Tom Corson, the president and chief operating officer of RCA Records, which released Timberlake's album.

The label had projected that "20/20" would sell 500,000 to 600,000 units, Corson said.

Timberlake, 31, was strategic about promoting his comeback effort: He performed at the Grammy Awards, hosted and hit the stage at "Saturday Night Live" and spent an entire week on "Late Night with Jimmy Fallon." The singer also partnered with Target for the album's deluxe edition and "20/20" streamed on iTunes a week before it was released.

Timberlake came up with the idea of a weeklong stint himself, Fallon said.

"I think he mentioned it to me like a year ago that he's working on something and wanted to do a week on our show," Fallon said Tuesday.

"20/20" is an unconventional album that features a mesh of R&B, soul, pop and futuristic sounds. The 10 tracks average seven minutes each.

Corson believes Timberlake's key to promoting the album was "less is more."

"While it felt like he was everywhere, he didn't do a lot of things because he didn't have to. But he did big things," he said.

Fallon even joked that other celebrities are trying to follow in Timberlake's footsteps with a weeklong stay on his show.

"We're getting a lot of phone calls now to do themed-weeks for people," said Fallon, who added that the show's writers and producers developed a load of material for "Timberweek."

"We have enough for another month," he said. "We could have 'Timbermonth.' Trust me, NBC is already pitching it to me."

Of the 19 albums to sell more than 900,000 in a single week, Timberlake holds three slots. His albums with 'N Sync, 2000's "No Strings Attached" and 2001's "Celebrity," sold 2.4 million and 1.9 million in their first week, respectively. Backstreet Boys, Lil Wayne and Taylor Swift have two albums each that have hit that level.

The excitement over the new album has also boosted sales of Timberlake's other solo albums, Nielsen Co. said. Last year, "FutureSex/LoveSound" and 2002's "Justified" sold 39,000 and 21,000 copies each, but this year they've already sold 29,000 and 17,000, respectively.

"As the marketing sort of picks up for the new record and the single goes to radio ... you definitely start to see interest," said David Bakula, Nielsen's senior vice president of client development and analytics for entertainment.

Bakula said 'N Sync sales are up, too.

Fallon said Timberlake worked tirelessly ahead of the five shows and he's proud of his friend's success.

"Justin was here till 11 o'clock most nights choreographing dance moves so he nailed it the next night," he said. "And he was sick at the time."

Corson said this week's success could change the expectation of Timberlake's follow-up to "20/20," which will likely be released later this year.

"It sure should," he said with a laugh. "Part two is now even more anticipated."

Timberlake could even show up for a stint on Fallon again.

"We are already talking about it," Fallon said.

Huawei Verge (MetroPCS)


MetroPCS users may get a lot more cell phones?to pick from when the carrier merges with T-Mobile, but none more simple than the Huawei Verge. For just $29, the Huawei Verge is the cheapest way to get unlimited talk and text on MetroPCS for just $40 per month. Unfortunately, that's about the only thing this phone has going for it. The Verge packs a poor camera, and practically no multimedia features. It's fine for a backup line, or the occasional call, but keep looking if you want anything more than that.

Design, Call Quality, and Apps
The Verge measures 4.57 by 2.06 by 0.49 inches (HWD) and weighs just 3.17 ounces. It looks and feels like a toy. The handset is made from cheap-feeling black plastic?matte on the back and shiny on the front. The 2.4-inch display features 320-by-240 pixel resolution. Like everything else about this phone, it's serviceable. Below the display are some function keys and a five-way control pad. And below those are four tiny rows of number keys that are clicky and well separated, though the backlighting is strangely uneven.

The Verge is a tri-band 2G 1xRTT (850/1700/1900 MHz) device with no Wi-Fi. The phone is 2G only, as MetroPCS lacks a 3G data network. The carrier has 4G LTE, but only some of its smartphones operate on it. Slow data aside, $40 per month gets you unlimited talk, text, and Web data. That makes the Verge a great deal, provided you live in a MetroPCS coverage area and can put up with the slow internet speeds.

Considering this phone's primary purpose is voice calling, the Verge only sounds average. Volume is loud in the phone's earpiece, though voices sound somewhat thin and hollow. On the other end, calls made with the phone sound clear enough, though background noise cancellation is poor. The speakerphone gets fairly loud, but it also begins to distort at higher volumes. Calls sounded fine through a Jawbone Era Bluetooth headset , but there's no voice dialing. Battery life was average at 7 hours and 17 minutes of talk time.

Apps, Multimedia, and Conclusions
The Verge has the same simple interface we've seen on other MetroPCS feature phones. The home screen has links to the main menu, apps, and widgets. The main menu is home to all of your standard features, like call logs, contacts, messages, a music player, settings, and tools. Apps pulls up icons of all your Web-based applications on the phone's home screen, and Widgets gives you quick access to a clock, calendar, and weather info, all splashed on top of your home screen.

The Obigo 5.0 browser does a decent job with WAP sites, but it's so slow that, combined with the 2G data, browsing the Web feels more like a chore than a benefit. Considering that you're paying for data as part of your monthly plan, it would be wise to choose a phone that can surf more adeptly. Email and IM clients are included for most standard accounts, and both worked fine. All of the typical apps make an appearance as well, including an alarm clock, calculator, notepad, stopwatch, and world clock.

You get 30MB of free internal memory. There's no microSD card slot, so what you see is what you get. Fortunately, you can't do much with the Verge, so that limited storage can go a long way. There's no music or video playback, so you're limited to the few apps on the phone, the slow Web browser, and a limited selection of apps from MetroPCS to keep you entertained.

Don't get this phone for the 1.3-megapixel camera?it's not good. Photos are so blurry and undefined they look like they were taken underwater. The only way to get the images off your phone is to send them via email or picture message. It should go without saying there's no video capture, perhaps out of mercy.

If you have no use for a phone outside of making phone calls, the Huawei Verge is your least expensive option on MetroPCS. But if you want a phone that does more than the bare minimum, you'll probably have more luck with the Huawei Pinnacle 2, which is the carrier's only other feature phone right now. We haven't reviewed it yet, but it's a modest update to the Huawei Pinnacle. At the very least, it gets you a decent BlackBerry-style keyboard, along with a music player. Considering you don't have to pay for an additional data plan, it might also be worth it to look into getting a smartphone. It'll cost the same $40 per month, but will expand your capabilities dramatically. A good place to start is the LG Motion 4G, which gets you a lot of Android bang for just a little more than the price of the Verge.

Trees used to create recyclable, efficient solar cell

Mar. 26, 2013 ? Solar cells are just like leaves, capturing the sunlight and turning it into energy. It's fitting that they can now be made partially from trees.

Georgia Institute of Technology and Purdue University researchers have developed efficient solar cells using natural substrates derived from plants such as trees. Just as importantly, by fabricating them on cellulose nanocrystal (CNC) substrates, the solar cells can be quickly recycled in water at the end of their lifecycle.

The technology is published in the journal Scientific Reports, the latest open-access journal from the Nature Publishing Group.

The researchers report that the organic solar cells reach a power conversion efficiency of 2.7 percent, an unprecedented figure for cells on substrates derived from renewable raw materials. The CNC substrates on which the solar cells are fabricated are optically transparent, enabling light to pass through them before being absorbed by a very thin layer of an organic semiconductor. During the recycling process, the solar cells are simply immersed in water at room temperature. Within only minutes, the CNC substrate dissolves and the solar cell can be separated easily into its major components.

Georgia Tech College of Engineering Professor Bernard Kippelen led the study and says his team's project opens the door for a truly recyclable, sustainable and renewable solar cell technology.

"The development and performance of organic substrates in solar technology continues to improve, providing engineers with a good indication of future applications," said Kippelen, who is also the director of Georgia Tech's Center for Organic Photonics and Electronics (COPE). "But organic solar cells must be recyclable. Otherwise we are simply solving one problem, less dependence on fossil fuels, while creating another, a technology that produces energy from renewable sources but is not disposable at the end of its lifecycle."

To date, organic solar cells have been typically fabricated on glass or plastic. Neither is easily recyclable, and petroleum-based substrates are not very eco-friendly. For instance, if cells fabricated on glass were to break during manufacturing or installation, the useless materials would be difficult to dispose of. Paper substrates are better for the environment, but have shown limited performance because of high surface roughness or porosity. However, cellulose nanomaterials made from wood are green, renewable and sustainable. The substrates have a low surface roughness of only about two nanometers.

"Our next steps will be to work toward improving the power conversion efficiency over 10 percent, levels similar to solar cells fabricated on glass or petroleum-based substrates," said Kippelen. The group plans to achieve this by optimizing the optical properties of the solar cell's electrode.

Purdue School of Materials Engineering associate professor Jeffrey Youngblood collaborated with Kippelen on the research.

A provisional patent on the technology has been filed with the U.S. Patent Office.

There's also another positive impact of using natural products to create cellulose nanomaterials. The nation's forest product industry projects that tens of millions of tons of them could be produced once large-scale production begins, potentially in the next five years.

The research is the latest project by COPE, which studies the use and development of printed electronics. Last year the center created the first-ever completely plastic solar cell.

Hope for Galapagos wildlife threatened by marine invaders

Mar. 26, 2013 ? Increasing tourism and the spread of marine invasive non-native species is threatening the unique plant and marine life around the Galapagos Islands.

UK scientists from the Universities of Southampton and Dundee are currently investigating the extent of the problem following a grant from the UK Government's Darwin Initiative, which aims to protect biodiversity and promote sustainability around the world.

UK Environment Minister Richard Benyon said: "The UK has played a major role in supporting the establishment of the Galapagos Marine Reserve and our Darwin Initiative has funded a range of important projects protecting and enhancing both marine and terrestrial wildlife.

"Invasive non-native species can cause huge damage to local ecosystems and I am delighted that action is being taken to monitor this threat."

Project leader Dr Ken Collins, Ocean and Earth Science of University of Southampton based at the National Oceanography Centre said: "Tourism is partly to blame for the influx of invasive non-native species, due to the huge rise in ships and planes from mainland Ecuador bringing in pests. In recent years, it was realised that cargo ships were carrying disease-infected mosquitoes, which were attracted to the ship's bright white deck lights. Simply changing from conventional filament bulbs to yellow sodium lamps, along with fumigation in the hold has substantially reduced the threat.

"We are trying to protect marine biodiversity by identifying newly arrived species to the Galapagos, assessing if they have the potential to compete for space and overcome other species of algae and native corals."

White coral, which has already been reported off the mainland Ecuador coast (600 miles away), is also causing anxiety. It could easily hitch a lift on the frequent vessels supplying Galapagos tourists and residents. Already, two new algae species have been found in the Galapagos Marine Reserve, a World Heritage Site.

Another species causing concern and which has the potential to overwhelm natural populations is the Indian Ocean lionfish. This fish colonised the Caribbean through accidental release from an aquarium and has spread through the entire Caribbean in the last decade. Its rapacious appetite has led to the decimation of coral reef fish populations in the southern Caribbean. Lionfish can consume prey up to two thirds of their own length and data shows that they can eat 20 small wrasses in 30 minutes. Their stomachs can expand by up to 30 times in volume when consuming a large catch. The Panama Canal could provide a short cut to Ecuador's Pacific coast and then the Galapagos.

One of Ken Collin's PhD students is Fadilah Ali, who is at the University of Southampton studying how the lionfish is eating its way through coral reef fish populations in the southern Caribbean. For over a hundred years Southampton, one the UK's busiest ports has been receiving marine hitchhikers from around the world, changing the entire balance of its underwater marine plants and animals. One example is the Pacific Oyster, which is being studied in the Solent region by another of Ken's PhD students Steff Deane.

Prof Terry Dawson, SAGES Chair in Global Environmental Change at Dundee, added, "Invasive species are becoming one of the greatest threats to biodiversity on a global scale. The Galapagos islands are particularly vulnerable due to the fact that much of the indigenous wildlife have evolved over millions of years in the absence of predators, competition, pests and diseases, which makes them very susceptible to the negative impacts of aggressive non-native species.

"We are very pleased to have Inti Keith, one of the staff of the Charles Darwin Research Station, registered with the University of Dundee to study for her PhD on this important topic. Her extensive local knowledge of the marine environment of the Galapagos Islands gives us a head start in developing the research to tackle the issue.

The team have recently returned from the Galapagos, where they met the Ecuadorian Navy and DIRNEA, the national maritime authority, to discuss control measures and helped take part in the first underwater survey of the Galapagos capital port.
