City center or Pyongyang, North Korea.
Maps of North Korea's landscape have for decades been largely blank, but thanks to "a community of citizen cartographers," Google Maps has managed to fill in some of the blanks.
Tapping input submitted to its Google Map Maker tool, the Web giant has added more detailed, up-to-date information to its maps of the reclusive nation, including streets, names, and other points of interest.
Jayanth Mysore, Google's senior product manager of Map Maker, discussed in a company blog post the effort behind assembling the new data:
To build this map, a community of citizen cartographers came together in Google Map Maker to make their contributions such as adding road names and points of interest. This effort has been active in Map Maker for a few years and today the new map of North Korea is ready and now available on Google Maps. As a result, the world can access maps of North Korea that offer much more information and detail than before.
One area where the changes are most apparent is in the city of Pyongyang, where highways, parks, and even subway stations have been added. Google provided the following examples:

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)
By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.
If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)
The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.

Sarai Sierra, the New York mother who disappeared in Turkey while on a solo trip, took several side excursions out of the country, but stayed in contact with her family the entire time, a family friend told ABC News.
Turkish media reported today that police were trying to establish why Sierra visited Amsterdam and Munich. Police were also trying to establish the identity of a man Sierra, 33, was chatting with on the Internet, according to local media.
Rachel Norman, a family friend, said the man was a group tour guide from the Netherlands and said Sierra stayed in regular touch with her family in New York.
Steven Sierra, Sarai's husband, and David Jimenez, her brother, arrived in Istanbul today to aid in the search.
The men have been in contact with officials from the U.S. consulate in the country and plan to meet with them as soon as they open on Tuesday, Norman said.
After that, she said Sierra and Jimenez would meet with Turkish officials to discuss plans and search efforts.

Sarai Sierra was supposed to fly back to the United States on Jan. 22, but she never showed up for her flight home.
Her two boys, ages 11 and 9, have not been told their mother is missing.
Sierra, an avid photographer, left New York on Jan. 7. It was her first overseas trip, and she decided to go ahead after a friend had to cancel, her family said.
"It was her first time outside of the United States, and every day while she was there she pretty much kept in contact with us, letting us know what she was up to, where she was going, whether it be through texting or whether it be through video chat, she was touching base with us," Steven Sierra told ABC News before he departed for Istanbul.
But when it came time to pick her up from Newark Liberty International Airport in New Jersey, Sierra wasn't on board her scheduled flight.
Steven Sierra called United Airlines and was told his wife had never boarded the flight home.
Further investigation revealed she had left her passport, clothes, phone chargers and medical cards in her room at a hostel in Beyoglu, Turkey, he said.
The family is suspicious and said it is completely out of character for the happily married mother, who met her husband in church youth group, to disappear.
The U.S. Embassy in Turkey and the Turkish National Police are involved in the investigation, WABC-TV reported.
"They've been keeping us posted, from my understanding they've been looking into hospitals and sending out word to police stations over there," Steven Sierra said. "Maybe she's, you know, locked up, so they are doing what they can."
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.

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.

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.
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.
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.

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.
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.
