It's that time of year again! The lull between Apple product releases, which means -- yep, you guessed it -- mystery parts.


The latest, courtesy of 9to5Mac, is a little more exciting than camera modules and home buttons. In fact, it may or may not be the back of the next iPad, perched next to a black
iPad Mini for comparison.


Some disclaimers: The image's point of origin is unknown, as is its possible legitimacy. However, the little scuff marks on the back and masking tape around the antennas do nothing but add to the intrigue.


Apple is, of course, expected to roll out another new iPad later this year. In fact, it would be strange if the company didn't. Apple's last release of a full-size iPad came right alongside that of the iPad Mini last October, an update that brought some improved internals and the ire of those who plunked down on the third-generation model just months earlier.


The photo comes about a day after a report that Apple's cooking up a mid-release cycle update to its fourth-generation iPad to offer a 128GB model. That would be double the 64GB size, which is the current top-of-the-line capacity on the iPhone and iPad.

Space Pictures This Week: Martian Gas, Cloud Trails

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.

US Mom Missing in Turkey Took Side Trips













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."

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.

Tokyo stocks open up 0.7%






TOKYO: Tokyo stocks opened 0.70 percent higher on Monday after the yen continued to fall against other major currencies.

The Nikkei 225 index at the Tokyo Stock Exchange was up 76.21 points at 11,002.86 at the start.

"The weaker yen continues to fuel the ongoing rally," said SMBC Nikko Securities general manager of equities Hiroichi Nishi.

"And with earnings reporting season kicking into high gear this week, companies' outlooks for the (January-March) fourth quarter will be closely watched," he told Dow Jones Newswires.

The dollar was at 91.09 yen in early Asian trade, up from 90.87 yen in New York Friday afternoon.

The euro rose to $1.3466 and 122.54 yen from $1.3457 and 122.28 yen in US trade.

Bullish Wall Street activity was also encouraging, with the much-watched S&P 500 closing above the 1,500 mark for the first time in five years on Friday.

The broad-based S&P 500 added 0.54 percent to 1,502.96 as strong earnings reports from Procter and Gamble, Halliburton and other equities propelled US markets higher.

The Dow Jones Industrial Average closed up 0.51 percent to 13,895.98, its best level since October 2007.

Pornographic video clips already showing up on Twitter's Vine




Less than a week after Twitter unveiled Vine, the video-sharing app apparently has developed a porn problem.


Released Thursday, the app for iPhone and
iPod Touch lets anyone create and share six-second clips, but it also has become a popular venue for male genitalia and pornographic movies taped off TVs and laptops. As first pointed out last night by The New York Times' Nick Bilton, searches for #porn, #sex, and other associated tags brings up a handful of videos featuring male exhibitionism and other activity.


While Vine's terms of service don't expressly forbid sexually explicit content, Twitter does encourage users to use good judgment when posting content:


You are responsible for your use of the Services, for any Content you post to the Services, and for any consequences thereof. The Content you submit, post, or display will be able to be viewed by other users of the Services and through third party services and websites. You should only provide Content that you are comfortable sharing with others under these Terms.


However, Vine users can flag videos they find offensive. If clips receive enough complaints, Twitter will add a warning still to the beginning of the video that users have to bypass to see the clip, a Twitter representative told CNET.




"Uploaded videos that are reported and determined to violate our guidelines will be removed from the site, and the user that posted the video may be terminated," the representative said in a statement.


Long an advocate for freedom of expression, Twitter has been reluctant to censor tweets. A year ago, the microblogging site announced it would be willing to remove tweets on a country-by-country basis when there are local restrictions against specific content in the tweets.


While the NSFW content might not violate Twitter's TOS, Apple's App Store guidelines state that "apps containing pornographic material, defined by Webster's Dictionary as 'explicit descriptions or displays of sexual organs or activities intended to stimulate erotic rather than aesthetic or emotional feelings,' will be rejected."


Apple recently removed an app called 500px, presumably because of its photo-sharing capabilities, which might allow users to search for and find naked bodies. CNET has contacted Apple for comment and will update this report when we learn more.

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."

Brazil Nightclub Fire Deadliest in More Than Decade













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.



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 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.



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.

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.

Germany has 'everlasting responsibility' for Nazi crimes: Merkel

 





BERLIN: Germany has "an everlasting responsibility" for the crimes committed by the Nazis, Chancellor Angela Merkel said Saturday, just days ahead of the 80th anniversary of Adolf Hitler's takeover of power.

"Naturally, we have an everlasting responsibility for the crimes of national-socialism, for the victims of World War II, and above all, for the Holocaust," Merkel said in a podcast on her website.

Her remarks came as the world prepares to mark Holocaust Memorial Day on January 27, the date in 1945 when the Soviet army liberated the Auschwitz concentration camp in then occupied Poland.

In another significant date, Wednesday will mark eight decades since Hitler was appointed chancellor on January 30, 1933 by then president Paul von Hindenburg.

"We must clearly say, generation after generation, and say it again: with courage, civil courage, each individual can help ensure that racism and anti-Semitism have no chance," Merkel added.

"We're facing our history, we're not hiding anything, we're not repressing anything. We must confront this to make sure we are a good and trustworthy partner in the future, as we already are today, thankfully," she said.
