Lift-door stickers to drive home fire hazard message






SINGAPORE: The Singapore Civil Defence Force (SCDF) has unveiled lift-door stickers with fire safety messages as part of a campaign to generate greater public awareness on the dangers of discarding items at common areas such as corridors, lift lobbies, staircases and void decks.

One such sticker was unveiled by Senior Minister of State for Home Affairs and Foreign Affairs, Mr Masagos Zulkifli, at Blk 819, Tampines West Avenue 3 on Sunday.

The senior minister of state is also an MP for Tampines GRC.

Fires involving discarded items at common areas in HDB estates account for almost a quarter of the total number of residential fires in 2012.

SCDF says such fires have the potential to be more serious in nature due to the high fire load present and proximity to dwellings.

18 people were injured in 707 fires involving discarded items last year.

SCDF says leaving discarded items at the common areas, especially combustible items such as furniture and newspapers, can easily fuel fires when lighted materials such as cigarette butts are indiscriminately thrown onto them.

Cluttered common areas can also seriously hamper fire-fighting efforts, fire evacuation and conveyance of patients during a medical emergency.

BARCELONA, Spain--Will Nokia unleash another Lumia smartphone?


Nokia kicks off the first official day of Mobile World Congress with its press conference, and you can get all the news right here.


Rather than a high-end superphone, Nokia is expected to unveil a line of more budget-friendly phones in a bid to go after the mass market. That could mean a lower-end Lumia device, as well phones from its Asha line of ultra-low-end phones.


CNET UK's Luke Westaway, photographer Sarah Tew, and I will be bringing you all the details, photos, and commentary from the event. The event kicks off at 11:30 p.m. PT on Sunday, or 8:30 a.m. Monday in local Barcelona time.

Nokia's Mobile World Congress press conference


Nokia, like many cellphone makers, is on the road to recovery, and it's still unclear where the company is headed. Its line of Lumia smartphones has won critical praise, but it doesn't yet have a blockbuster hit like Apple's iPhone or the Galaxy S from Samsung.



Still, the company has made steady progress expanding its distribution. In the U.S., it just got back into the game with Verizon with the Lumia 620, and CEO Stephen Elop has hinted at a potential flagship down the line.


We'll see if Nokia can keep up its momentum with whatever new products it launches tomorrow.


As usual, we'll be using ScribbleLive to bring you live text and photos, blow by blow. We'll start the live blog about 15 minutes before Nokia officially kicks off its event.

Elderly Abandoned at World's Largest Religious Festival


Every 12 years, the northern Indian city of Allahabad plays host to a vast gathering of Hindu pilgrims called the Maha Kumbh Mela. This year, Allahabad is expected to host an estimated 80 million pilgrims between January and March. (See Kumbh Mela: Pictures From the Hindu Holy Festival)

People come to Allahabad to wash away their sins in the sacred River Ganges. For many it's the realization of their life's goal, and they emerge feeling joyful and rejuvenated. But there is also a darker side to the world's largest religious gathering, as some take advantage of the swirling crowds to abandon elderly relatives.

"They wait for this Maha Kumbh because many people are there so nobody will know," said one human rights activist who has helped people in this predicament and who wished to remain anonymous. "Old people have become useless, they don't want to look after them, so they leave them and go."

Anshu Malviya, an Allahabad-based social worker, confirmed that both men and women have been abandoned during the religious event, though it has happened more often to elderly widows. Numbers are hard to come by, since many people genuinely become separated from their groups in the crowd, and those who have been abandoned may not admit it. But Malviya estimates that dozens of people are deliberately abandoned during a Maha Kumbh Mela, at a very rough guess.

To a foreigner, it seems puzzling that these people are not capable of finding their own way home. Malviya smiles. "If you were Indian," he said, "you wouldn't be puzzled. Often they have never left their homes. They are not educated, they don't work. A lot of the time they don't even know which district their village is in."

Once the crowd disperses and the volunteer-run lost-and-found camps that provide temporary respite have packed away their tents, the abandoned elderly may have the option of entering a government-run shelter. Conditions are notoriously bad in these homes, however, and many prefer to remain on the streets, begging. Some gravitate to other holy cities such as Varanasi or Vrindavan where, if they're lucky, they are taken in by temples or charity-funded shelters.

In these cities, they join a much larger population, predominantly women, whose families no longer wish to support them, and who have been brought there because, in the Hindu religion, to die in these holy cities is to achieve moksha or Nirvana. Mohini Giri, a Delhi-based campaigner for women's rights and former chair of India's National Commission for Women, estimates that there are 10,000 such women in Varanasi and 16,000 in Vrindavan.

But even these women are just the tip of the iceberg, says economist Jean Drèze of the University of Allahabad, who has campaigned on social issues in India since 1979. "For one woman who has been explicitly parked in Vrindavan or Varanasi, there are a thousand or ten thousand who are living next door to their sons and are as good as abandoned, literally kept on a starvation diet," he said.

According to the Hindu ideal, a woman should be looked after until the end of her life by her male relatives—with responsibility for her shifting from her father to her husband to her son. But Martha Chen, a lecturer in public policy at Harvard University who published a study of widows in India in 2001, found that the reality was often very different.

Chen's survey of 562 widows of different ages revealed that about half of them were supporting themselves in households that did not include an adult male—either living alone, or with young children or other single women. Many of those who did live with their families reported harassment or even violence.

According to Drèze, the situation hasn't changed since Chen's study, despite the economic growth that has taken place in India, because widows remain vulnerable due to their lack of education and employment. In 2010, the World Bank reported that only 29 percent of the Indian workforce was female. Moreover, despite changes in the law designed to protect women's rights to property, in practice sons predominantly inherit from their parents—leaving women eternally dependent on men. In a country where 37 percent of the population still lives below the poverty line, elderly dependent relatives fall low on many people's lists of priorities.

This bleak picture is all too familiar to Devshran Singh, who oversees the Durga Kund old people's home in Varanasi. People don't pay toward the upkeep of their relatives, he said, and they rarely visit. In one case, a doctor brought an old woman to Durga Kund claiming she had been abandoned. After he had gone, the woman revealed that the doctor was her son. "In modern life," said Singh, "people don't have time for their elderly."

Drèze is currently campaigning for pensions for the elderly, including widows. Giri is working to make more women aware of their rights. And most experts agree that education, which is increasingly accessible to girls in India, will help improve women's plight. "Education is a big force of social change," said Drèze. "There's no doubt about that."

Las Vegas Strip Shooting Suspect ID'd












Las Vegas police identified a suspect today in a shooting on the strip that caused a Maserati to hit a taxi and burst into flames, killing three people.


Ammar Harris, 26, has been named a suspect in the Thursday skirmish that killed three people, including rapper Kenny Clutch.


The altercation between Harris and Clutch, 27, whose legal name was Kenneth Cherry Jr., is believed to have originated in the valet area of a Las Vegas hotel, police said.


Police said Harris fired several rounds into a Maserati that was being driven by Cherry as both vehicles continued northbound on glitzy Las Vegas Boulevard.


The rapper's expensive sports car careened out of control after he was shot, slamming into several cars, including a taxi. The impact caused the cab to burst into flames, killing the driver, Michael Boldon and a female passenger. Witnesses said it looked like the car exploded.


"He was a number one guy," Carolyn Jean Trimble, Boldon's sister, told ABC News.

"I looked out my window and I could see one vehicle down here on the corner of the intersection totally engulfed in flames," witness John Lamb told ABC News.


Boldon, 62, and his passenger, who has not yet been identified, were both killed, as was Clutch.


Timble said her brother loved driving his taxi around Vegas.


"He came to live with me in Las Vegas last year to help take care of our mother, and the first day he got here he said, 'I have to get a job.' The second day, I came home from work, and he said he got a job," she recalled.


"He says, 'You'll never guess what it is,' and I said, 'what,' and he said, 'taxi cab driver,' and we both fell out laughing," Trimble said. "He loved that job. He never complained. He'd come home and tell me stories about what happened, who he picked up."


Boldon was a single father who raised a 36-year-old son and was a new grandfather. His grandson was named after him, Trimble said.


"Of all the people to take from this earth," she said. "But I guess the Lord needed him."


A passenger in the Maserati was hit and sustained only a minor injury to his arm. Clutch died at University Medical Center.


His father, Kenneth Cherry Sr., expressed his grief for the loss of his son while speaking with ABC News.


"This is something you never really, really ever want to experience as a parent, to lose a child before you go," he said.


Harris is described as 5-foot-11 and 180 pounds. Anyone with information is asked to contact the Las Vegas Metro Police Department's homicide division.

Rusty rocks reveal ancient origin of photosynthesis



































SUN-WORSHIP began even earlier than we thought. The world's oldest sedimentary rocks suggest an early form of photosynthesis may have evolved almost 3.8 billion years ago, not long after life appeared on Earth.











A hallmark of photosynthesis in plants is that the process splits water and produces oxygen gas. But some groups of bacteria oxidise substances like iron instead – a form of photosynthesis that doesn't generate oxygen. Evolutionary biologists think these non-oxygen-generating forms of photosynthesis evolved first, giving rise to oxygen-generating photosynthesis sometime before the Earth's atmosphere gained oxygen 2.4 billion years ago (New Scientist, 8 December 2012, p 12).













But when did non-oxygen-generating photosynthesis evolve? Fossilised microbial mats that formed in shallow water 3.4 billion years ago in what is now South Africa show the chemical fingerprints of the process. However, geologists have long wondered whether even earlier evidence exists.












The world's oldest sedimentary rocks – a class of rock that can preserve evidence of life – are a logical place to look, says Andrew Czaja of the University of Cincinnati in Ohio. These rocks, which are found in Greenland and date back almost 3.8 billion years, contain vast deposits of iron oxide that are a puzzle. "What could have formed these giant masses of oxidised iron?" asks Czaja.


















To investigate, he analysed the isotopic composition of samples taken from the oxidised iron. He found that some isotopes of iron were more common than they would be if oxygen gas was indiscriminately oxidising the metal. Moreover, the exact isotopic balance varied subtly from point to point in the rock.












Both findings make sense if photosynthetic bacteria were responsible for the iron oxide, says Czaja. That's because these microbes preferentially oxidise only a small fraction of the dissolved iron, and the iron isotopes they prefer vary slightly as environmental conditions change (Earth and Planetary Science Letters, doi.org/kh5). His findings suggest that this form of photosynthesis appeared about 370 million years earlier than we thought.












It is "the best current working hypothesis for the origin of these deposits", says Mike Tice of Texas A&M University in College Station – one of the team who analysed the 3.4-billion-year-old microbial mats from South Africa.












William Martin at the University of Düsseldorf, Germany, agrees. "Anoxygenic photosynthesis is a good candidate for the isotope evidence they see," he says. "Had these fascinating results been collected on Mars, the verdict of the jury would surely remain open," says Martin Brasier at the University of Oxford. "But [on Earth] opinion seems to be swinging in the direction of non-oxygen-generating photosynthesis during the interval from 3.8 to 2.9 billion years ago."

Basketball: Lakers cap emotional week with win over Trail Blazers






LOS ANGELES: Kobe Bryant scored 29 of his 40 points in the second half as the Los Angeles Lakers capped an emotional week with a much-needed 111-107 NBA victory over the Portland Trail Blazers.

Bryant added seven rebounds and two steals for the Lakers, who have won seven of their last 10 games and stand 3-1/2 games behind the Houston Rockets for the eighth and final playoff spot in the Western Conference standings.

In an interview with Sports Illustrated published this week, Bryant said he was certain the Lakers would make the playoffs.

"It's not a question of if we make the playoffs. We will," Bryant insisted.

The team, which has had more than its share of dysfunctional moments this season, has been through an emotional five days since the death on Monday of 80-year-old owner Jerry Buss.

Buss was remembered at the first Lakers game following his death, a 113-99 win over Boston on Wednesday.

At a memorial service on Thursday Bryant challenged his teammates to live up to Buss' standards of excellence.

"We're playing for something bigger than ourselves, bigger than a single season. We are playing for a great man, Dr. Jerry Buss," he said.

Playing hours after Buss was buried on Friday, the Lakers remained mindful of his legacy, Bryant said.

"I think we understand what's at stake and what this franchise stands for," Bryant said. "That gives you an extra gear."

Dwight Howard added 19 points and 16 rebounds for the Lakers, and Antawn Jamison chipped in 16 points.

JJ Hickson scored with 22 points and 11 rebounds for the slumping Blazers, who have now lost seven in a row to slip 1-1/2 games behind the Lakers.

Cyberattacks Bring Attention to Security Reform











Recent accusations of a large-scale cyber crime effort by the Chinese government left many wondering what immediate steps the president and Congress are taking to prevent these attacks from happening again.


On Wednesday, the White House released the administration's Strategy on Mitigating the Theft of U.S. Trade Secrets as a follow-up to the president's executive order. The strategy did not outwardly mention China, but it implied U.S. government awareness of the problem.


"We are taking a whole of government approach to stop the theft of trade secrets by foreign competitors or foreign governments by any means -- cyber or otherwise," U.S. Intellectual Property Enforcement Coordinator Victoria Espinel said in a White House statement.


As of now, the administration's strategy is the first direct step in addressing cybersecurity, but in order for change to happen Congress needs to be involved. So far, the Cyber Intelligence Sharing and Protection Act (CISPA) is the most notable Congressional legislation addressing the problem, despite its past controversy.


Last April, CISPA was introduced by House Intelligence Committee Chairman Mike Rogers, R-Mich., and Rep. Dutch Ruppersberger, D-Md. The act would allow private companies with consumer information to voluntarily share those details with the NSA and the DOD in order to combat cyber attacks.

The companies would be protected from any liabilities if the information was somehow mishandled. This portion of the act sounded alarm bells for CISPA's opponents, like the ACLU, which worried that this provision would incentivize companies to share individuals' information with disregard.


CISPA passed in the House of Representatives, despite a veto threat from the White House stemming from similar privacy concerns. The bill then died in the Senate.


This year, CISPA was reintroduced the day after the State of the Union address during which the president declared an executive order targeting similar security concerns from a government standpoint.


In contrast to CISPA, the executive order would be initiated on the end of the government, and federal agencies would share relevant information regarding threats with private industries, rather than asking businesses to supply data details. All information shared by the government would be unclassified.


At the core of both the executive order and CISPA, U.S. businesses and the government would be encouraged to work together to combat cyber threats. However, each option would clearly take a different route to collaboration. The difference seems minimal, but has been the subject of legislative debates between the president and Congress for almost a year, until now.


"My response to the president's executive order is very positive," Ruppersberger told ABC News. "[The president] brought up how important information sharing is [and] by addressing critical infrastructure, he took care of another hurdle that we do not have to deal with."


Addressing privacy roadblocks, CISPA backers said the sharing of private customer information with the government, as long as personal details are stripped, is not unprecedented.


"Think of what we do with HIPAA in the medical professions; [doctors do not need to know] the individual person, just the symptoms to diagnose a disease," Michigan Gov. John Engler testified at a House Intelligence Committee hearing in an attempt to put the problem into context.

Synthetic llama antibodies soothe arthritis pain


































ARTHRITIS may have met its match, in the form of the llama immune system. Antibodies similar to ones originally discovered in camels and llamas have helped to heal moderate to severe arthritis in a small trial.













The antibodies have inspired the design of a drug, ALX-0061, that blocks a receptor for interleukin 6. This signalling molecule amplifies inflammation, leading to sore and swollen joints. The symptoms ease once the receptor is blocked.











In the trial, 24 patients received one of three unchanging doses of ALX-0061 for six months. Another group received a placebo. Sixty-three per cent of those given the drug saw their symptoms practically vanish when measured using a standard metric, the DAS28 scale, which evaluates symptoms in 28 joints. This figure is more than twice the 30 per cent remission rate seen with the current "gold-standard" rival treatment Actemra (tocilizumab). Tocilizumab also targets interleukin 6, but it is based on a normal-sized mammalian antibody.













The remission rate was even higher – 75 per cent – for the eight patients given one of the three doses: 3 milligrams per kilogram of body weight administered once every four weeks. "These data suggest that out of every 10 patients, seven to eight could experience rapid, durable responses to their symptoms," says Josi Holz, the chief medical officer of Ablynx, in Ghent, Belgium, which released its results on 13 February.












According to Ed Moses, CEO of Ablynx, it could be the tiny size of the molecule – one-fifth the usual size – that gives it the edge over existing antibody-based treatments. "It potentially gives far faster and deeper penetration of diseased joints," he says.












Other researchers caution against over-optimism because the trial was short and small. "If the results are repeated in randomised, controlled, double-blinded studies, then they would be very impressive," says David Scott, chief medical adviser to the UK's National Rheumatoid Arthritis Society.












To take ALX-0061 forward, Ablynx is now looking for a partner to help finance such a larger, decisive trial.
