DNA privacy: don't flatter yourself

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.

US senators unveil immigration reform deal

WASHINGTON: Eight US lawmakers crossed party lines to unveil a plan Monday that would provide a pathway to citizenship for 11 million illegal immigrants currently living in the shadows in the United States.

"We recognise that our immigration system is broken," the senators said in their bipartisan framework, a copy of which was obtained by AFP.

It promises a "tough but fair" path to citizenship for undocumented immigrants, reform that would build the US economy, an "effective" employment verification system and an improved process to admit future workers.

The proposed legislation also increases the number of drones and other surveillance equipment, as well as the number of agents at and between ports of entry in a bid to better secure the long borders the United States shares with Canada to the north and especially Mexico to the south.

Although the bill seeks to boost security measures, it also vows to "strengthen prohibitions against racial profiling and inappropriate use of force", as well as improve training for border patrol agents and increase oversight.

In a bid to combat visa overstays, the lawmakers offered a requirement for those in the country illegally to register with the government.

Around 40 percent of the illegal immigrants now in the United States entered the country legally but then let their visa expire, according to official estimates.

But under the plan, they would also be able to earn "probationary" legal status -- to live and work legally in the US -- after passing a background check and paying a fine and back taxes.

Those with a "serious" criminal background or who otherwise threaten US national security would not be eligible for legal status and would face deportation, according to the framework document.

"Individuals with probationary legal status will be required to go to the back of the line of prospective immigrants" and pass an additional background check, among other requirements, the document said.

Under the plan, individuals who fulfil the requirements could eventually obtain a green card for permanent residency.

Senators backing the measure are Republicans John McCain, Marco Rubio, Lindsey Graham and Jeff Flake, along with Democrats Robert Menendez, Chuck Schumer, Dick Durbin and Michael Bennet.

New iPad 4 reportedly in the works -- perhaps a 128GB model

Are you ready for an iPad with beefier memory?

A new fourth-generation
iPad with Retina display -- and perhaps as much as 128 gigabytes of memory -- is being readied for release, sources tell 9to5Mac. The upcoming slate would not be a new design but rather an addition to the current fourth-generation line, with the same color and wireless combinations as the iPad 4, these unnamed sources say.

Pricing is unknown, but the new model is described as a "premium SKU" (stock keeping unity) that would join the current lineup of 16GB, 32GB, and 64GB iPads. A source at a large U.S. retailer provided 9to5Mac with what is purportedly a new SKU listing for iPads that includes a fourth model labeled as "Ultimate" to join its current lineup

CNET has contacted Apple for comment and will update this report when we learn more.

9to5Mac suspects the new model will have 128GB thanks to code found in the
iOS 6.1 beta 5 that references a compatibility with 128GB iOS devices. The discovery was first noted yesterday by @iNeal on Twitter.

That tweet led Jeff Benjamin at iDownloadBlog to extract the iOS 6.1 and compare the System Partition Padding values found in old iOS 6.x firmware. What he found was an additional field for 128:

9to5Mac notes that if this purported iPad is in the works, it might be not be intended for the general consumer but rather perhaps for government or even retail use.

Doomed Dolphin Speaks to New York's Vibrant Wildlife

By the time New Yorkers spied a dolphin swimming through the superfund sludge of the Gowanus Canal last Friday, it was too late. The marine mammal didn't even survive long enough for a rescue plan to come together. First sighted on Friday afternoon, the dolphin perished at 6:00 p.m.

The reason the marine mammal died, and why the dolphin swam up the polluted waterway in the first place, is as yet unknown. But the sad story of the wayward creature highlights the strange nature of New York City, the global epitome of urbanity. Hidden within Gotham are native carnivores, marine mammals, and even species that have scarcely been seen before.

Marine mammals are arguably the most high-profile of New York City's wild residents and visitors. The Gowanus Canal dolphin was only the latest to venture within city limits. Just a month ago, a 60-foot-long finback whale (Balaenoptera physalus) became stranded in the Rockaway Inlet of Queens. The emaciated animal died the day after it was discovered.

There seems to be no singular reason explaining why marine mammals such as the Gowanus dolphin and Queens' finback whale wander up the city's rivers or strand on beaches. Each case is unique. But not all the city's marine mammal visitors suffer terrible fates.

In 2006, a hefty manatee (Trichechus spp.) took a long jaunt from its Florida home up the East Coast, including a detour down New York's Hudson River. The sirenian survived the trip, continuing on to Cape Cod before reportedly turning back south to a destination unknown. Hopefully the manatee didn't encounter any great white sharks (Carcharodon carcharias) on the return journey, a marine predator we know patrols the waters off New York.

Of course, New York City's whales, seals, and occasional manatee can only skirt the city along its shores and canals. You likely won't see a seal caterpillaring its way along Broadway.

Yet the city's interior also hosts a strange accumulation of wildlife, including native animals that are carving out spaces for themselves in the concrete corridors and exotic species that we have introduced to city life.

Coyotes (Canis latrans) may be the cleverest of New York City's hidden wildlife. Thanks to camera traps, and the occasional police chase through Lower Manhattan, researchers are keeping track of the wily canids and studying how they are so successfully taking up residence in many of the nation's cities. "Most small, urban parks will likely hold a pair and their offspring at most—coyotes are very territorial," said Cornell University ecologist Paul Curtis.

The secretive carnivorans bring a welcome element to urban neighborhoods—an appetite for rodents—and are experts at cracking open new niches alongside people.

Black bears (Ursus americanus) may be next. The bears have proliferated in northern New Jersey in recent years, and in 2010, a black bear came within three miles of the George Washington Bridge, a major thoroughfare between New Jersey and Manhattan. The bear obviously would have eschewed rush hour traffic and the tolls, but the local population is so bountiful that it's not unreasonable to think some enterprising bear might eventually wander into the big city.

Strangely, you may actually be more likely to run into a crocodylian predator in New York City than a black bear. New Yorkers have a nagging habit of importing—and losing-alligator—like caimans and other reptiles within the city.

In 2010, an 18-inch long caiman took refuge under a parked Datsun in Astoria, Queens. No one knows how the reptile wound up on the street, but given the trend of owners buying cute crocodylians and later dumping them, someone may have abandoned the poor little caiman.

This would hardly be the first time. In 2006, another little caiman was found in the leaf litter behind Brooklyn's Spring Creek Towers, while "Damon the Caiman" swam around a Central Park lake in the summer of 2001. These caimans are only some of the most famous—according to a New York Times report, the Brooklyn-based Animal Care and Control deals with about ten caimans each year.

Many other unusual and exotic animals have romped through New York. Under some of their most notable animal celebrities, the city's Parks and Recreation department lists guinea pigs, boa snakes, and even a tiger that escaped from a circus in 2004 and ran down Jackie Robinson Parkway before his owners were able to get him back.

The Big Apple even contains species that have never been documented before. No, not the ballyhooed "Montauk Monster"—actually a rotted raccoon—but a distinct species of leopard frog. Described early this year, the cryptic amphibian was given away by its unique mating call.

'Barrier of Bodies' Trapped Nightclub Fire Victims

A fast-moving fire roared through a crowded, windowless nightclub in southern Brazil early Sunday, filling the air in seconds with flames and a thick, toxic smoke that killed more than 230 panicked partygoers, many of whom were caught in a stampede to escape.

Inspectors believe the blaze began when a band's small pyrotechnics show ignited foam sound insulating material on the ceiling, releasing a putrid haze that caused scores of university students to choke to death. Most victims died from smoke inhalation rather than burns in what appeared to be the world's deadliest nightclub fire in more than a decade.

Survivors and the police inspector Marcelo Arigony said security guards briefly tried to block people from exiting the club. Brazilian bars routinely make patrons pay their entire tab at the end of the night before they are allowed to leave.

But Arigony said the guards didn't appear to block fleeing patrons for long. "It was chaotic and it doesn't seem to have been done in bad faith because several security guards also died," he told The Associated Press.

Later, firefighters responding to the blaze initially had trouble getting inside the Kiss nightclub because "there was a barrier of bodies blocking the entrance," Guido Pedroso Melo, commander of the city's fire department, told the O Globo newspaper.

Brazil Nightclub Fire: Nearly 200 People Killed Watch Video

Authorities said band members who were on the stage when the fire broke out later talked with police and confirmed they used pyrotechnics during their show.

Police inspector Sandro Meinerz, who coordinated the investigation at the nightclub, said one band member died after escaping because he returned inside the burning building to save his accordion. The other band members escaped alive because they were the first to notice the fire.

"It was terrible inside — it was like one of those films of the Holocaust, bodies piled atop one another," said Meinerz. "We had to use trucks to remove them. It took about six hours to take the bodies away."

Television images from Santa Maria, a university city of about 260,000 people, showed black smoke billowing out of the Kiss nightclub as shirtless young men who attended the university party joined firefighters using axes and sledgehammers to pound at the hot-pink exterior walls, trying to reach 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 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. About half of those killed were men, about half women.

The party was organized by students from several academic departments from the Federal University of Santa Maria. Such organized university parties are common throughout Brazil.

Get cirrus in the fight against climate change

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.

India sees push for police reform after rape outcry

NEW DELHI: Sixteen-year-old Seenu was walking to her grandmother's house along a quiet street in northern India when a group of men dragged her into a car, took her to a secluded field and raped her in turns.

They filmed the act on their mobile phones and forced a pill into her mouth. She woke up an hour later, naked, bloodied, disoriented. The sun was just beginning to set as she put on her jeans and made her way back home.

When her father -- a gardener belonging to the "untouchable" or Dalit community which lies at the bottom of India's caste system -- found out what had happened to his only daughter, he killed himself.

Over the days that followed, Seenu (not her real name) and her mother made several trips to the nearest police station, defying threats from her upper-caste attackers, some of whom she knew.

Finally, when the Dalit community in her village held public protests and piled pressure on the police, the first arrest was made -- two weeks after the gang-rape. Since then, seven more men have been arrested.

Now living at her grandmother's home with six police officers as protection ahead of a court appearance next month, Seenu told AFP that rape victims like herself have problems reporting the crime "because police don't respect them".

"It makes me so angry. Why don't the police listen? Why don't they do their job? Why do they have to humiliate the girl or treat her like it's her fault she got raped?" she said, speaking softly so the officers did not overhear.

The gruesome gang-rape and murder of a student in New Delhi on December 16 last year prompted nationwide protests and a public outcry over how police handle sexual assault cases.

A beleaguered central government announced several safety measures earlier this month, including more night-time patrols by police in Delhi and the presence of at least a dozen female officers at every police station.

India suffers from a massive shortfall in the number of police on duty, currently employing only 129 officers per 100,000 people, according to data published in 2010 by the UN Office on Drugs and Crime.

This compares to 227 officers per 100,000 people in the United States.

Also, in many cases police have been found displaying the same sexist prejudices prevalent in Indian society, leading them sometimes to encourage rape survivors to marry their attackers.

Last week, a judge at a Delhi court ordered police to pay 25,000 rupees ($470) as compensation to a 13-year-old rape survivor, for refusing to file a complaint and pushing her to settle the case with the alleged rapist.

J.S. Verma, a former chief justice of India heading a government commission looking into sex crime, lambasted the police on Wednesday for their apathy and "low and skewed priority of dealing with complaints of sexual assault".

In his report, Verma also called for an end to the so-called "two finger test", a practice decried as demeaning and flawed in which doctors attempt to determine if a rape victim is sexually active.

Stung by the hail of criticism, police officials in Delhi recently revived a "gender sensitisation" programme that originally ran from 2008-2011, enrolling all personnel on the course in a bid to improve their handling of women.

Delhi Police Commissioner Neeraj Kumar promised that the force had been "jolted," leading it to "look at offences against women in a totally different way".

The government's plans to improve policing also include measures to recruit more women, who make up just 6.5 percent of the force, according to figures in the National Crime Records Bureau.

Maurice Nagar police station could be a model for the future. Located near a sprawling university campus, the recruitment of women has long been a priority and a female officer is required to be present at all hours.

The khaki-clad guards outside are female, the officer who registers complaints is female and many of the officers on duty, zipping in and out of traffic on motorbikes are female.

But even here an officer, Nazma Khan, dismisses the notion that police reform is a panacea.

"These crimes happen because of people with a messed-up mentality, who are everywhere," she told AFP.

"If we want to change the mentality then it has to change at school level, at homes, in the family, otherwise recruitment (of police) will not make a difference," she added.

To Seenu, the Dalit teenager whose parents cast off centuries of prejudice and oppression to educate their daughter and raise her to dream of someday becoming a doctor, such arguments offer no consolation.

"If the police don't change, girls like me will never get justice and soon enough, people will just stop expecting any justice in India."

The ultimate gall of a heartless iPhone thief

An object of desire?

(Credit:
CNET)

One should never expect justice in life.

The best one can hope for is poetry.

And yet, just once or twice, both manage to collide with a deliciousness that moves the soul.

Here is the tale of a teenage girl who had her iPhone stolen.

As The New York Times composes it, the girl had her
iPhone 4S ripped from her by a teenage boy in Brooklyn's notoriously difficult Prospect Park.

iPhone theft is rather popular in New York. Indeed, Mayor Bloomberg recently suggested that it's responsible for an increase in crime in the city.

Anyway, the iPhone-less girl collared a couple of policemen, but the miscreant was not to be found.

However, the thief then decided that he'd try to get some money for the phone. So he met a man on a Flatbush street -- as you do.

The man asked to take a look at the phone. Perhaps he wanted to see whether Siri was still inside.

Then, he ran off with it.

Yes, this is slightly poetic. But we've only just begun.

You see, the boy thief was not very happy. After all, he'd had his recently acquired property stolen. So he went off in search of a policeman to report the crime.

I pause for your sound effects.

Thank you.

More Technically Incorrect

The police reacted with unusual efficiency. They corralled both the boy and the man who had taken Siri from him. But they still assumed the boy was the victim.

Are you ready for verse three?

The phone rang. It was the girl trying to do a deal to get her phone back. The police realized something might be amiss here. This seemed to be a miss who actually owned the phone.

So they waited for her to arrive in Flatbush. She recognized the boy's sneakers. They were pink.

I pause for your further sound effects.

The police decided it was time to play Solomon. They would slice the phone in two if one party didn't renounce their claim to the phone.

No, wait. They asked both the girl and the pink-sneakered boy to unlock the phone with the PIN code.

You're already there, aren't you? Both the actual thieves were brought to justice -- the actual kind. And the girl got her phone back.

There are several morals to this story.

One, don't steal iPhones if you're wearing pink sneakers.

Two, if someone does unto you as you have done unto someone else, take it onto the chin. It will help you understand the feelings of others.

Three, if you're the kind of New Yorker who thinks they can always get away with it, well, you can't. Not always.

Pictures: The Story Behind Sun Dogs, Penitent Ice, and More

Photograph by Art Wolfe, Getty Images

If you want the beauty of winter without having to brave the bone-chilling temperatures blasting much of the United States this week, snuggle into a soft blanket, grab a warm beverage, and curl up with some of these natural frozen wonders.

Nieve penitente, or penitent snow, are collections of spires that resemble robed monks—or penitents. They are flattened columns of snow wider at the base than at the tip and can range in height from 3 to 20 feet (1 to 6 meters). The picture above shows the phenomenon in central Chile. (See pictures of the patterns in snow and ice.)

Nieve penitente tend to form in shallow valleys where the snow is deep and the sun doesn't shine at too steep an angle, said Kenneth Libbrecht, a physicist at the California Institute of Technology in Pasadena who studies ice crystal formation.

As the snow melts, dirt gets mixed in with the runoff and collects in little pools here and there, he said. Since the dirt is darker in color than the surrounding snow, the dirty areas melt faster "and you end up digging these pits," explained Libbrecht.

"They tend to form at high altitude," he said. But other than that, no one really knows the exact conditions that are needed to form penitent snow.

"They're fairly strong," Libbrecht said. "People have found [the spires] difficult to hike through."

Squatter, Bank of America Battle for $2.5M Mansion

Bank of America is taking a Florida man to court after he attempted to use an antiquated state law to legally take possession of a $2.5 million mansion that is currently owned by the bank.

Andre "Loki" Barbosa has lived in a five-bedroom Boca Raton, Fla., waterside property since July, and police have reportedly been unable to remove him.

The Brazilian national, 23, who reportedly refers to himself as "Loki Boy," cites Florida's "adverse possession" law, in which a party may acquire title from another by openly occupying their land and paying real property tax for at least seven years.

The house is listed as being owned by Bank of America as of July 2012, and that an adverse possession was filed in July. After Bank of America foreclosed on the property last year, the Palm Beach County Property Appraiser's Office was notified that Barbosa would be moving in, according to the South Florida Sun-Sentinel.

The Sun-Sentinel reported that he posted a notice in the front window of the house naming him as a "living beneficiary to the Divine Estate being superior of commerce and usury."
On Facebook, a man named Andre Barbosa calls the property "Templo de Kamisamar."

After Barbosa gained national attention for his brazen attempt, Bank of America filed an injunction on Jan. 23 to evict Barbosa and eight unidentified occupants.

In the civil complaint, Bank of America said Barbosa and other tenants "unlawfully entered the property" and "refused to permit the Plaintiff agents entry, use, and possession of its property." In addition to eviction, Bank of America is asking for $15,000 in damages to be paid to cover attorney's expenses.

Police were called Dec. 26 to the home but did not remove Barbosa, according to the Sentinel. Barbosa reportedly presented authorities with the adverse possession paperwork at the time.

Mark Potok, a senior fellow at the Southern Povery Law Center, says police officers may be disinclined to take action even if they are presented with paperwork that is invalid.

"A police officer walks up to someone who is claiming a house now belongs to him, without any basis at all, is handed a big sheaf of documents, which are incomprehensible," Potok said. "I think very often the officers ultimately feel that they're forced to go back to headquarters and try to figure out what's going on before they can actually toss someone in the slammer."

A neighbor of the Boca property, who asked not be named, told ABCNews.com that he entered the empty home just before Christmas to find four people inside, one of whom said the group is establishing an embassy for their mission, and that families would be moving in and out of the property. Barbosa was also among them.

The neighbor said he believes that Barbosa is a "patsy."

"This young guy is caught up in this thing," the neighbor said. "I think it's going on on a bigger scale."

Barbosa could not be reached for comment.

The neighbor said that although the lights have been turned on at the house, the water has not, adding that this makes it clear it is not a permanent residence. The neighbor also said the form posted in the window is "total gibberish," which indicated that the house is an embassy, and that those who enter must present two forms of identification, and respect the rights of its indigenous people.

"I think it's a group of people that see an opportunity to get some money from the bank," the neighbor said. "If they're going to hold the house ransom, then the bank is going to have to go through an eviction process.

"They're taking advantage of banks, where the right hand doesn't know where the left hand is," the neighbor said. "They can't clap."
