DNA privacy: don't flatter yourself

Labels: World

The secrets contained in our individual genomes are less valuable than we like to believe

IMAGINE donating your DNA to a project aimed at discovering links between genes and diseases. You consent to your genome sequence being released anonymously into the public domain, though you are warned there is a remote possibility that it might one day be possible to link it back to you.

A few years later, that remote possibility comes to pass. How should you feel? This is no longer a hypothetical scenario. About 50 people who participated in a project called 1000 Genomes have been traced (see "Matching names to genes: the end of genetic privacy?").

The researchers' intentions were honourable. They have not revealed these identities, and the original data has been adjusted to make a repeat using the same technique impossible. All they wanted to do was expose privacy issues.

Consider them exposed. It is clear that genomics has entered a new phase, similar to that which social media went through a few years ago, when concerns were raised about people giving away too much personal information.

What happens when the same applies to our DNA? Having your genome open to public scrutiny obviously raises privacy issues. Employers and insurers may be interested. Embarrassing family secrets may be exposed.

But overall, personal genetic information is probably no more revealing than other sorts. In fact there are reasons to believe that it is less so: would an insurance company really go to the trouble of decoding a genome to discover a slightly elevated risk of cancer or Alzheimer's disease?

The available evidence suggests not. In 2006, Harvard University set out to sequence the genomes of 100,000 volunteers and make them publicly available, along with personal information such as names and medical records. One of the goals was to see what happens when such data is open to all. The answer seems to be "not a lot". So far this Personal Genome Project has published 148 people's full genomes. Not one volunteer has reported a privacy issue.

This is not a reason for complacency, but it suggests that our genomic secrets are less interesting to other people than we might like to believe.

Govt to tighten law to better protect timeshare consumers

Labels: Technology

SINGAPORE: The government is tightening safeguards and plugging loopholes in the law to better protect consumers in timeshare deals.

The Ministry of Trade and Industry (MTI) said on Monday that it is making the changes because timeshare businesses continue to account for the most number of consumer complaints.

The number of timeshare cases totalled 389 in 2010 and 358 in 2011, according to the Consumers Association of Singapore.

MTI said an increasing number of businesses has moved from selling conventional timeshare -- which is the right to use a timeshare accommodation for a specified period -- to selling holiday club memberships.

These club memberships involve an advance payment for the right to obtain holiday benefits, such as discounted accommodation and airfares.

MTI said such holiday clubs essentially offer a similar product to timeshare, but they are not subject to the cooling-off period under the law as they do not fall under the current definition of "regulated contract".

Consumers are not given the opportunity to assess whether a holiday club can offer the purported discounts.

There is also a lack of transparency about important features in timeshare and holiday club contracts, including the rights of the consumer and the obligations of the timeshare seller.

Thus MTI is proposing changes to the Consumer Protection (Fair Trading) (Cancellation of Contracts) Regulations.

A key change is in the definition of "regulated contract". This will be expanded to include "long-term holiday product contracts" to close the current loophole where certain timeshare operators deliberately modify their business model to escape the requirements under the law.

This will also give consumers of holiday clubs the same protection as timeshare contracts, such as a five-day cooling-off period.

No money is to be collected during the cooling-off period. MTI said this will increase the protection and reduce the incentives for errant businesses to force a sale.

It will also remove the risk of losing, as well as the inconvenience of recovering the money paid, when consumers decide to cancel the deal during the cooling-off period.

MTI wants to hear from the public and welcomes feedback and views over the next five weeks till March 1.

Massive loss of life in Brazil nightclub fire

Labels: Health

Last Updated 5:17 p.m. ET

BRASILIA, Brazil Flames raced through a crowded nightclub in southern Brazil early Sunday, killing more than 230 people as panicked partygoers gasped for breath in the smoke-filled air, stampeding toward a single exit partially blocked by those already dead. It appeared to be the world's deadliest nightclub fire in more than a decade.

Witnesses said a flare or firework lit by band members started the blaze in Santa Maria, a university city of about 225,000 people, though officials said the cause was still under investigation.

More than 200 die in Brazil nightclub fire

Television images showed smoke pouring out of the Kiss nightclub as shirtless young men who had attended a university party joined firefighters using axes and sledgehammers to pound at windows and walls to free those trapped inside.

Guido Pedroso Melo, commander of the city's fire department, told the O Globo newspaper that firefighters had a hard time getting inside the club because "there was a barrier of bodies blocking the entrance."

Teenagers sprinted from the scene desperately seeking help. Others carried injured and burned friends away in their arms.

"There was so much smoke and fire, it was complete panic, and it took a long time for people to get out, there were so many dead," survivor Luana Santos Silva told the Globo TV network.

The fire spread so fast inside the packed club that firefighters and ambulances could do little to stop it, Silva said.

Another survivor, Michele Pereira, told the Folha de S. Paulo newspaper that she was near the stage when members of the band lit flares that started the conflagration.

"The band that was onstage began to use flares and, suddenly, they stopped the show and pointed them upward," she said. "At that point, the ceiling caught fire. It was really weak, but in a matter of seconds it spread."

Guitarist Rodrigo Martins told Radio Gaucha that the band, Gurizada Fandangueira, started playing at 2:15 a.m. "and we had played around five songs when I looked up and noticed the roof was burning"

"It might have happened because of the Sputnik, the machine we use to create a luminous effect with sparks. It's harmless, we never had any trouble with it.

"When the fire started, a guard passed us a fire extinguisher, the singer tried to use it but it wasn't working"

He confirmed that accordion player Danilo Jacques, 28, died, while the five other members made it out safely.

Police Maj. Cleberson Braida Bastianello said by telephone that the toll had risen to 233 with the death of a hospitalized victim. Officials counted 232 bodies that had been brought for identification to a gymnasium in Santa Maria, a major university city with about 250,000 residents at the southern tip of Brazil, near the borders with Argentina and Uruguay.

An earlier count put the number of dead at 245.

Federal Health Minister Alexandre Padhilha told a news conference that most of the 117 people treated in hospitals had been poisoned by gases they breathed during the fire. Only a few suffered serious burns, he said.

Brazil President Dilma Roussef arrived to visit the injured after cutting short her trip to a Latin American-European summit in Chile.

"It is a tragedy for all of us," Roussef said.

Most of the dead apparently suffocated, according to Dr. Paulo Afonso Beltrame, a professor at the medical school of the Federal University of Santa Maria who went to the city's Caridade Hospital to help victims.

'Barrier of Bodies' Trapped Nightclub Fire Victims

Labels: Business

A fast-moving fire roared through a crowded nightclub in southern Brazil early Sunday, within seconds filling the space with flames and a thick, toxic smoke that killed more than 230 panicked partygoers who gasped for breath and fought in a stampede to escape.

It appeared to be the world's deadliest nightclub fire in more than a decade.

Firefighters responding to the blaze at first had trouble getting inside the Kiss nightclub because bodies partially blocked the club's entryway.

Witnesses said a flare or firework lit by band members started the blaze in Santa Maria, a university city of about 260,000 people. Officials at a news conference said the cause was still under investigation — though police inspector Sandro Meinerz told the Agencia Estado news agency the band was to blame for a pyrotechnics show and that manslaughter charges could be filed.

Television images showed black smoke billowing out of the Kiss nightclub as shirtless young men who had attended a university party joined firefighters using axes and sledgehammers to pound at windows and hot-pink exterior walls to free those trapped inside.

Bodies of the dead and injured were strewn in the street and panicked screams filled the air as medics tried to help. There was little to be done; officials said most of those who died were suffocated by smoke within minutes.

Within hours a community gym was a horror scene, with body after body lined up on the floor, partially covered with black plastic as family members identified kin.

Outside the gym police held up personal objects — a black purse, a blue high-heeled shoe — as people seeking information on loved ones looked crowded around, hoping not to recognize anything being shown them.

Teenagers sprinted from the scene after the fire began, desperately seeking help. Others carried injured and burned friends away in their arms. Many of the victims were under 20 years old, including some minors.

"There was so much smoke and fire, it was complete panic, and it took a long time for people to get out, there were so many dead," survivor Luana Santos Silva told the Globo TV network.

The fire spread so fast inside the packed club that firefighters and ambulances could do little to stop it, Silva said.

Get cirrus in the fight against climate change

Labels: World

FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.

In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.

Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.

The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).

But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.

Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."

Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

Latin America, Europe back free trade

Labels: Technology

SANTIAGO: European and Latin American leaders pledged here Saturday to shun protectionism and boost their strategic partnership to foster free trade.

Some 60 countries are represented at the summit between the 27-member European Union and the Community of Latin American and Caribbean States (CELAC).

Set up in Caracas in December 2011 at the behest of Venezuela, CELAC groups all nations from across the Americas except the United States and Canada and aims to boost regional trade and integration.

Chilean President Sebastian Pinera, the two-day summit's host, opened the session with a call for a new "strategic alliance to achieve sustainable development."

And indeed participants unanimously adopted a summit statement extolling their "strategic partnership to achieve sustainable development."

They also reiterated their commitment "to avoid protectionism in all its forms" and to "favour an open and non-discriminatory, ruled-based multilateral trade system."

"We firmly reject all coercive measures of unilateral character with extra-territorial effect that are contrary to international law and the commonly accepted rules of free trade," the statement said.

The leaders also pledged to continue working together "toward a new international financial architecture."

And they backed concrete actions to bolster law enforcement cooperation "to dismantle criminal organizations, all within the full respect of human rights and international law."

There was also support for the convening of a special UN General Assembly session on the global drug problem.

The leaders also gave a nod to "the universality and indivisibility of human rights as laid out in the Universal Declaration of Human Rights."

It was the seventh summit between the two blocs but the first since the creation of CELAC. The two sides agreed to hold the next EU-CELAC summit in Brussels in 2015.

The EU is the biggest outside investor in Latin America, accounting for three percent of direct foreign investment in CELAC or $385 billion in 2010.

EU officials noted that the figure exceeds the combined investment in China, Russia and India.

"We need a strong political commitment to rein in protectionism and promote liberalization," European Commission President Jose Manuel Barroso told a meeting of business chiefs leaders shortly before the political summit's opening.

Powerful German Chancellor Angela Merkel, whom the Chilean press has dubbed "Europe's boss," called for "cooperation without barriers to trade."

"The dynamic development of this entire region shows that we, within the EU, must strive to ensure we are not left behind, to improve our competitiveness, reduce our debt. We cannot live on the backs of future generations," she added.

The Europeans are particularly keen on securing the speedy conclusion of a free trade pact between the EU and the South American trading bloc Mercosur.

Negotiations have so far stumbled over differences on agriculture -- notably Europe's subsidies to its farmers, which undermine Latin America's efforts to sell its own products.

Argentine President Cristina Kirchner, who has taken some protectionist measures, said that the EU-Mercosur negotiations, launched in 2004, must restart on a "new basis" that can clear the way for a deal.

"The negotiations with the EU cannot be based on decisions made in 2004. We need new premises, first among all Mercosur members, not just between Brazil and Argentina," she said after a bilateral session with Rousseff.

Kirchner suggested establishing an ad hoc Mercosur panel to come up with new proposals and make a new offer to the EU later this year.

Meanwhile, a Venezuelan minister said here that President Hugo Chavez has beaten a severe respiratory infection that occurred after his latest cancer surgery in Cuba.

"The respiratory infection has been overcome, although there still is some degree of breathing difficulty that is being treated appropriately," Communications Minister Ernesto Villegas said on the sidelines of a EU-CELAC summit.

Chavez, who had surgery on December 12, has not been seen in public since he left Caracas for surgery at a hospital in Cuba.

Monday, the 33 CELAC leaders will hold their own summit here, with Cuba taking over chairmanship from Chile for one year. They are hoping to overcome ideological and economic differences to foster greater regional integration.

The meeting will seal Cuba's full regional reintegration and mark a major diplomatic coup for 81-year-old President Raul Castro. Cuba, the only non-democratic Communist-ruled country in the Americas, has been under a US economic embargo since 1962.

U.S. steps up military involvement in Mali

Labels: Lifestyle

Mali military battles Islamist insurgents

STORY HIGHLIGHTS

NEW: United States agrees to conduct aerial refueling missions, to transport troops

Malian and French forces recapture the city of Gao, a stronghold of the Islamic militants

The Malian offensive is backed by French forces

(CNN) -- The United States is intensifying its involvement in Mali, where local and French forces are battling Islamic militants.

It will support the French military by conducting aerial refueling missions, according to the Pentagon, which released a short statement Saturday following a call between Defense Secretary Leon Panetta and French Defense Minister Jean-Yves Le Drian.

"The leaders also discussed plans for the United States to transport troops from African nations, including Chad and Togo, to support the international effort in Mali. Secretary Panetta and Minister Le Drian resolved to remain in close contact as aggressive operations against terrorist networks in Mali are ongoing," it read.

U.S. policy prohibits direct military aid to Mali because the fledgling government is the result of a coup. No support can go to the Malian military directly until leaders are chosen through an election.

But the United States is supporting the effort with intelligence and airlift support.

So far, the U.S. Air Force has flown at least seven C-17 cargo missions into Mali, carrying 200 passengers, mainly French troops, and 168 tons of equipment, according to Maj. Robert Firman, a Pentagon spokesman.

The uptick in U.S. involvement comes as Malian forces loosened the grip that Islamist militants' hold in the country's north with the retaking of the city of Gao.

With the support of French forces, the Malians entered and took control of Gao, which for months had been a militant stronghold, the French defense ministry said.

The advance was made in stages, with forces taking Gao's airport and the main bridge leading to town before entering the rest of the city.

"Jihadist terrorists, who have fought Malian and French armies, have seen their mobile and logistical capabilities reduced," the ministry said in a news release.

The quickening advance of the government forces has brought them to the heart of the territory held by the militants.

Broken limbs, torn lives in northern Mali

The Islamic extremists carved out a large haven in northern Mali last year, taking advantage of a chaotic situation after a military coup by the separatist party MNLA. The militants banned music, smoking, drinking and watching sports on television. They also destroyed historic tombs and shrines.

The takeover stoked fear among global security experts that Mali could become a new hub for terrorism.

Refugees tell harrowing stories of life under the Islamist militants.

But the French-based International Federation for Human Rights said it is "very alarmed" by reports that Malian soldiers are themselves carrying out extrajudicial killings and abuses as they counterstrike.

The United Nations' refugee agency, UNHCR, has called for an increase in international aid for the hundreds of thousands of people who have been displaced by the fighting in the country.

More signs al Qaeda in Mali orchestrated Algeria attack

More than 150,000 refugees have fled Mali into neighboring countries, and another 230,000 are displaced inside Mali, the agency said.

The military's advance into Gao may shed more light on the conditions that residents there have faced. According to the U.N. agency, one former resident told of a hospital stripped of medicine by the armed militants and filling with bodies.

As the Malian troops advance, some other countries in the region are joining the French force aiding them. Between 700 and 800 African troops from Benin, Nigeria, Togo and Burkina Faso have arrived, U.S. State Department spokeswoman Victoria Nuland said Friday, and a number of Senegalese troops and up to 2,000 from Chad are on the way.

France has 2,150 soldiers on Malian soil, with 1,000 more troops supporting the operation from elsewhere.

French involvement in the conflict began on January 11, the day after militants said they had seized the city of Konna, east of Diabaly in central Mali, and were poised to advance south toward Bamako, the capital.

Until 1960, Mali had been under French control.

The MNLA, made up of ethnic Tuareg rebels, staged their coup against Mali's central government after returning to Mali well-armed from fighting for late Libyan leader Moammar Gadhafi.

1 officer killed, 2 wounded near La. casino

Labels: Health

Updated 8:50 PM ET

NEW ORLEANS Police on Saturday arrested a man suspected of fatally shooting a police officer and critically wounding two sheriff's deputies after allegedly setting fire to a mobile home in south Louisiana, where an elderly man's body was found.

A Chitimacha tribal officer was pronounced dead at the scene of the shootings in Charenton, while two St. Mary Parish sheriff's deputies were critically wounded and taken to local hospitals, said Louisiana State Police Trooper Stephen Hammons.

Hammons said the officers were responding to a report of an armed man walking down a road near the Cypress Bayou Casino when Wilbert Thibodeaux, 48, of Charenton allegedly shot them.

"Thibodeaux fired at the Chitimacha Officer, fatally wounding him," state police said in a news release. "As two St. Mary Deputies, who were in the same car, arrived at the scene Thibodeaux fired multiple shots hitting the deputies. During the encounter, Thibodeaux was shot."

Investigators found the burned remains of a man after extinguishing a fire at a mobile home that Thibodeaux is suspected of setting before the officers confronted him, Hammons said.

Police identified the deceased man in the mobile home as Eddie Lyons, 78, of Charenton. "Detectives suspect Lyons was shot by Thibodeaux before the fire," state police said in a news release.

Thibodeaux was treated at a hospital for a gunshot wound that wasn't considered life-threatening and released, according to Hammons, who said investigators were questioning him Saturday evening. Charges against him are pending.

The state Fire Marshal's office is investigating the fire.

"Today is a difficult day for our partners in St. Mary Parish," Col. Mike Edmonson, the State Police superintendent, said in a statement. "My thoughts and prayers are with the deputies and the officer's families tonight. I know the coming days and weeks will be difficult ones for the men and women of the Chitimacha Police Department and the St. Mary Parish Sheriff's Office. We will assist their agencies in any way we can during these trying times."

The casino is run by the Chitimacha Tribe of Louisiana and is less than a quarter-mile from the scene of the shootings. Hammons said the shootings occurred near but not on tribal land.

"Everybody is just in shock. It's small-town America," said Jacqueline Junca, the tribe's secretary and treasurer.

Police didn't immediately release the names of the officers. Authorities said they will do so at a Monday news conference.

Tribe councilman Toby Darden said the slain officer was married and had two grown children, but he declined to give his name.

"He's a real great guy. Extremely dedicated to his job. Very brave," Darden said.

He was one of seven full-time officers who patrol a 260-acre reservation that has roughly 150 homes, a grocery store, a small school and government offices.

"Everybody knows the officers personally," Darden said. "It's devastating."

Junca said the tribe has around 1,200 members, roughly half of whom live on the reservation.

Access to and from the casino was restricted for roughly 90 minutes as a precautionary measure while police responded to the shooting, said casino spokeswoman Nancy Herrington. Charenton is located about 45 miles southeast of Lafayette.

"We are very much in business and have been," Herrington said later Saturday. "We have events tonight. All of those are taking place."

A spokeswoman for the sheriff's office and a tribal police dispatcher referred questions about the shootings to the State Police.

"We've got a lot of unanswered questions," State Police Capt. Doug Cain said.

One of the injured deputies was taken to a hospital in New Orleans and the other was taken to a Lafayette hospital. Both were listed in critical but stable condition Saturday evening, Hammons said.

Newtown Families March for Gun Control in DC

gty gun control march washington jt 130126 wblog Newtown Victims Families Join Gun Control Activists on DC March

(YURI GRIPAS/AFP/Getty Images)

WASHINGTON, D.C. — Near-freezing temperatures didn’t stop several thousand gun-control activists from bearing their pickets today, carrying signs emblazoned with “Ban Assault Weapons Now” and the names of gun violence victims in a demonstration organized as a response to the mass shooting in Newtown, Conn. last month.

Walking in silence, the demonstrators trudged between Capitol Hill and the Washington Monument over a thin layer of melting snow. They were joined by politicians and some families of the Newtown victims.

March organizer Shannon Watts said the event was for the “families who lost the lights of their lives in Newtown, daughters and sons, wives and mothers, grandchildren, sisters and brothers gone in an unfathomable instant.”

“Let’s stand together and use our voices, use our votes to let legislators know that we won’t stand down until they enact common sense gun control laws that will keep our children out of the line of fire,” she told demonstrators.

Watts founded One Million Moms for Gun Control after the killing of 20 first graders and six adults at the Sandy Hook Elementary School in Newtown in December. In a profile with the New York Times, Watts said her 12-year-old son had suffered panic attacks after learning of last summer’s Aurora, Colo., theater shooting, leaving her at an impasse over how to talk to him about the latest tragedy.

Also among the speakers was a survivor of the 2007 Virginia Tech massacre, Collin Goddard.

“We need to challenge any politician who thinks it’s easier to ask an elementary school teacher to stand up to a gunman with an AR-15 than it is to ask them to stand up to a gun lobbyist with a checkbook,” he said.

The demonstration comes amid a push by progressive lawmakers to enact stricter gun control measures as a response to the trend of recent mass killings, although any hypothetical bill would likely face strong opposition in Congress.

Rep. Chris Van Hollen, D-Md., was among the demonstrators today.

“The idea that people need high-capacity magazines that can fire 30, 50, 100 rounds has no place in a civilized society,” he said. “Between the time we’re gathered here right now and this time of day tomorrow, across America, 282 Americans will have been shot.”

The congressman was quoting statistics compiled by the Brady Campaign to Stop Gun Violence.

INFOGRAPHIC: Guns by the Numbers

Last week President Obama proposed a sweeping overhaul of federal measures regulating gun ownership, including a universal background check system for sales, banning assault weapons, and curbing the amount of ammunition available in weapon clips.

An ABC News/Washington Post poll released Thursday found 53 percent of Americans viewed Obama’s gun control plan favorably, 41 percent unfavorably. The division was visible today, as a handful of gun-rights advocates also turned out on the National Mall to protest what they believe would be infringements on their Second Amendment liberties.
