Police have netted 31 people in three countries in the past 24 hours in a Europe-wide manhunt, after $50 million in uncut gems were stolen in a daring assault at the Brussels airport this February.
It?s a plotline that is worthy of a movie (it is probably being written at this very moment).?And it gripped the Belgian public. Perhaps no group more so than the jewelers across town who always face a certain vulnerability, simply because of the value of the goods behind their glass counters.
?Everyone was fascinated, but of course the jewelry workers are the most interested,? says a woman at an antique jewelry shop in a famous covered gallery in historic Brussels who wished not to share her name.
The Belgian prosecutor?s office said that on Tuesday that seven were arrested, including six people in Switzerland and one man in France, who could be a mastermind of the robbery. And in the early dawn today, some 200 police fanned across Belgium and detained two dozen more suspects, many of them criminals known to the Belgian justice system.
"We believe the man arrested in France is one of the authors of the robbery," said Jean-Marc Meilleur of the Brussels prosecutor's office.??"It's the only person that we can say at this stage they could have participated in the events on the tarmac. Among those arrested in Belgium, at least 10 are known to the court, including for armed attacks. They are part of the Brussels criminal underworld."?
Smooth operation
The robbery occurred on the evening of Feb. 18, 2013. As passengers buckled up and the plane got ready for takeoff, eight men in police uniform in two cars drove?through the fence of the Brussels airport and raced, with police lights flashing, across the runway.
Driving up to the plane, which had just been loaded with the gems, they held up the crew and forced open the cargo hold, loaded their vehicles with 120 packages totaling an estimated $50 million, and sped through the fence. No one was hurt. And it was so fast and precise that passengers are said to have not even been aware of what happened until it was over ? and their flight was cancelled.
This isn't the first time Belgium has been the scene of a diamond heist. Antwerp, a diamond capital, is just a thirty minute drive away from Brussels. But the events of this one captivated the globe. When a security guard was asked at a higher-end Brussels jewelry store ? where customers are attended to one by one and treated to champagne as they peruse fine jewels ? if he had followed the news, he said ?of course,? surprised by the question. He wasn?t authorized to share his name ? or to even talk (instead he was busy looking at the customers filing in).
Back at the antique store, the owner says her store has been held up twice in 20 years; the diamond store just in front of them was held up six months ago, she says. ?We are relieved they were caught,? she says, ?to know [the thieves] aren?t out there and ... the police are working and are not involved in it.?

Hubble tells a tale of galactic collisions
May 12, 2013 ? When we look into the distant cosmos, the great majority of the objects we see are galaxies: immense gatherings of stars, planets, gas, dust, and dark matter, showing up in all kind of shapes. A new Hubble picture registers several, but the galaxy catalogued as 2MASX J05210136-2521450 stands out at a glance due to its interesting shape.
This object is an ultraluminous infrared galaxy which emits a tremendous amount of light at infrared wavelengths. Scientists connect this to intense star formation activity, triggered by a collision between two interacting galaxies.
The merging process has left its signs: 2MASX J05210136-2521450 presents a single, bright nucleus and a spectacular outer structure that consists of a one-sided extension of the inner arms, with a tidal tail heading in the opposite direction, formed from material ripped out from the merging galaxies by gravitational forces.
The image is a combination of exposures taken by Hubble's Advanced Camera for Surveys, using near-infrared and visible light.

Woman Almost Dies After 40 Hour Gaming Session - Kotaku
Traveler's Thrombosis, or deep vein thrombosis is an affliction that is often associated with flying. However in China, it appears that it is more commonly associated with video gaming than it is with air travel, especially now that after a young woman developed the condition after a 4o hour gaming session.
The People's Daily reports that a 20 year-old female gamer was taken to the hospital in Fujian province after complaining about leg pains. The gamer, Xiao Han (a psuedonym), was diagnosed with the possibly life threatening ailment Deep Vein Thrombosis (DVT) at the hospital. After a gruelling treatment of surgery and medicine, Xiao Han is now fine.
When doctors asked what Xiao Han was doing prior to her leg pain, she explained that she had been playing an online game. Unfortunately the doctors didn't specify which online game, but they told the People's Daily that Xiao Han had spent the over 40 continuous hours sitting down playing.
DVT is a condition when blood clots in a deep vein of the leg. It causes mild to extreme pain and has the possibility of leading to death. Basically, the clots occur in the leg, depending on time and luck the clot breaks off and travels through the blood stream and flows into the lungs (or other organs). When it reaches the lungs it can cause severe issues which can lead to death. Symptoms of DVT are often swelling and redness of the legs.
DVT is commonly associated with air travel other activities of long sitting such as playing video games. According to the US Federal Aviation Administration, DVT is known to "occur in 1 out 1000 people in the general population" from various causes. Last year a young man in Taiwan died in an internet cafe as developing DVT during a long gaming session.
The People's Daily article was kind enough to point out methods to preventing DVT. It recommends that gamers should take breaks, get regular exercise and drink lots of water. Of course it failed to mention that gamers should be careful when they partake in ridiculous gaming marathons.

German court to hear case against ESM, ECB bond-buying in June
DEAR ABBY: I am a 47-year-old male, married for 26 years. I am hopelessly in love with my wife and still see her as the most beautiful woman in the world.I have always been self-employed and have sometimes been at the extremes of feast or famine. During the bad times, I often worked 110-plus-hour weeks to save the ship. Each time things have gotten really bad, my wife has had an affair to make up for the time, money and attention I can't provide her. I found out about her latest affair (her third) when I found a secret cellphone in her purse. ...

Owners pass 2 rules changes
PHOENIX (AP) ? Concerned with how it will be officiated, NFL owners delayed voting Tuesday on a rule change that would ban offensive players from using the crown of their helmets against defenders in the open field.
After approving two other rule changes to enhance player safety, they stalled on the more contentious issue. NFL senior vice president of football operations Ray Anderson said the owners plan to vote on it Wednesday before the meetings end.
The owners outlawed peel-back blocks anywhere on the field; previously, they were illegal only inside the tackle box. A player makes a peel-back block when he is moving toward his goal line, approaches an opponent from behind or the side, and makes contact below the waist.
The penalty will be 15 yards.
"... really under no circumstances will you be permitted to block low below the waist when you're blocking back towards your own end line," said Rams coach Jeff Fisher, co-chairman of the competition committee.
Also banned is overloading a formation while attempting to block a field goal or extra point. Defensive teams can now have only six or less players on each side of the snapper at the line of scrimmage. Players not on the line can't push teammates on the line into blockers, either.
The alignment violation is a 5-yard penalty. The pushing penalty is 15 yards for unnecessary roughness.
"There were injuries, yes," Fisher said. "Talking to coaches and the players, it's just not something they look forward to doing. It's like, 'Oh, we scored again? We have to go out there and protect, kick an extra point or try?'"
But the potential change that has drawn the most attention ? yes, even more than eliminating the infamous tuck rule, which seems to be a foregone conclusion and will be voted on Wednesday ? is prohibiting ball carriers outside the tackle box from lowering their helmets and making contact with defenders with the crown.
New York Giants owner John Mara, a member of the competition committee that has recommended the change, said there was "a chance" a vote could be tabled until the May meetings in Boston.
"There was a spirited discussion," Mara said.
Many coaches have said they are concerned about officiating such a new rule.
"In all fairness it's going to be tough on the officials, it's going to be tough to make that determination at live speed with one look," said John Harbaugh of the Super Bowl champion Baltimore Ravens.
Harbaugh noted that in the competition committee's examination of one week of play last season, it found five instances where a ball carrier was not protecting the ball or himself and lowered his helmet to make contact with a defender.
Dean Blandino, recently promoted to vice president of officiating, noted that five in 16 games was significant enough to consider banning the act.
Added Fisher:
"We want to make a serious attempt to get the shoulder back into the game. We are not saying the ball carrier cannot get small. We are not saying the ball carrier cannot protect the football, because if he is going to go down to cover the football, if the shoulder goes down, we know the head goes down, we understand that.
"Protecting the football is OK, providing you do not strike with the crown of your helmet, and that is what we are trying to differentiate."
Blandino said the league wants flags thrown only on the obvious calls. He also said in cases where a player is not penalized, he could still be subject to a fine if video review after the game determines he made contact with the crown.
The penalty will be a spot foul for 15 yards.
New senior director of officiating Alberto Riveron said if the offensive and defensive player are both committing the foul, it would be an offsetting penalty and the down replayed.
Riveron said the key to officiating the play is in showing the officials more plays that are legal.
"That will be a great way to train because as we know it, most of the shots we have seen are legal, most of the contact is legal," he said. "We are trying to get that one individual situation where the head is lowered ? and you can see on the field, you can see a player put his head down ? and the contact is with the crown and you can see it."

Pope Francis breaks tradition on first Sunday as head of church

VATICAN CITY ? Breaking with tradition, Pope Francis delivered off-the-cuff remarks about God?s power to forgive instead of reading from a written speech for the first Sunday window appearance of his papacy.
He also spoke only in Italian ? beginning with ??buon giorno? (Good day) and ending with ??buon pranzo? (Have a good lunch) ? instead of greeting the faithful in several languages as his last few predecessors had done.
His comments and humor delighted a crowd of more than 150,000 in St. Peter?s Square, drawing cheers and laughter.
In just five days, Francis? straightforward, spontaneous style has become immediate hallmark of his papacy.
Earlier Sunday, he made an impromptu appearance before the public from a side gate of the Vatican, startling passers-by and prompting cheers, before delivering a six minute homily ? brief by church standards ? at the Vatican?s tiny parish church.
Before he entered St. Anna?s church to celebrate Mass, he heartily shook hands with parishioners and kissed babies.
After Mass, Francis put his security detail to the test as he waded into the street just outside St. Anna?s Gate. As the traffic light at the intersection turned green, Francis stepped up to the crowd, grasping outstretched hands. The atmosphere was so casual that several people even gripped Francis on the shoulder.
A few minutes later as the traffic light turned red, Francis ducked back inside the Vatican?s boundaries to dash upstairs for the window appearance from the papal apartment in the Apostolic Palace.
The studio window was opened for the first time since Francis? predecessor, Benedict XVI, gave his last window blessing on Sunday, Feb. 24. Four days later, Benedict went into retirement, the first pontiff to do so in nearly 600 years.
Francis, the first pope from Latin America, was elected on March 13. He has been staying in a hotel on the Vatican?s premises until the papal apartment in the palace is ready.
Hundreds of extra traffic police were deployed Sunday morning to control crowds and vehicles, for it was also the day of Rome?s annual marathon.
Bus routes were rerouted and many streets were closed off in an attempt to channel the curious and faithful up the main boulevard from the Tiber river to St. Peter?s square.
Giant video screens were set up so the huge crowd could get a close-up look at Francis, and dozens of medical teams were on hand for any emergencies.
After the Mass, the pope stepped out jauntily from St. Anna?s Church and waved to a crowd of hundreds kept behind barriers across the street, and then greeted the Vatican parishioners one by one. One young man patted the pope on the back ? an indication of the informality that has been evident from the first moment of his papacy.
?Francesco! Francesco!? children shouted his name in Italian from the street. As he patted one little boy on the head, he asked ?Are you a good boy?? and the child nodded.
??Are you sure?? the pope quipped.
In his homily, Francis said the core message of God is ?that of mercy.? He said God has an unfathomable capacity to pardon and noted that people are often harder on each other than God is toward sinners.

Bobby Brown's getting put away.?Los Angeles City Attorney Spokesperson Frank Mateljan tells E! News that the singer was sentenced to 55 days in jail after pleading no contest Tuesday to driving under the influence and to driving on a suspended license (the license is suspended due to a prior conviction for driving under the influence.)
But that's not all.
Bobby Brown pleads not guilty to latest round of DUI charges
In addition to his jail time, Brown was placed on 48 months of summary probation, ordered to pay a $500 fine plus penalty assessment, complete the an 18-month alcohol program and comply with standard DUI conditions for his first charge.
On the second count, the he was placed on 36 months of summary probation, ordered to pay a $300 fine plus penalty assessment, install an ignition interlock device -- an alcohol Breathalyzer that prohibits the driver from starting the car if they blow above the limit.
Brown, who was not present in court today but represented by his attorney Tiffany Feder, will report to jail on March 20. As a condition of his surrender terms, he is to attend three AA classes a week.?
Bobby Brown slapped with multiple DUI counts
In November, the "Every Little Step" singer pleaded not guilty in a Los Angeles court to the multiple DUI charges resulting from his drunken driving bust the month prior, E! News has learned.
Brown was pulled over around 1 a.m. on Oct. 24, 2012, for driving carelessly near the city of Tarzana, Calif., and officers discovered he was behind the wheel without his court-mandated dashboard Breathalyzer.

No Wi-Fi, No Problem ? Restaurant Waitlisting App For iPad NoshList Comes To Smartphones
NoshList, the restaurant waitlisting app for iPad launched just over a year ago, is today making its way to smartphones, including both the iPhone and Android devices. Although possibly not the ideal form factor for the job, the mobile app allows restaurants to test the NoshList experience on devices they likely own, before making an investment into a tablet (or multiple tablets) to run the full-screen version. In addition, the new mobile apps can serve as backup if the restaurant's Wi-Fi connection ever goes down, as they'll maintain connectivity, whereas the more affordable, Wi-Fi only iPads would have lost their signal.Source: http://feedproxy.google.com/~r/Techcrunch/~3/kyChY1j3Z64/

European Commission invests ?50 million into 5G research with a 2020 target
You're still waiting to get 4G? That's old hat: the European Commission is already thinking about 5G. It's investing €50 million ($65.3 million) into research with the hope that the next-next-generation cellular technology will be a practical reality by 2020. About €16 million ($20.9 million) of that is headed toward METIS, an Ericsson-led alliance hoping to develop wireless with 10 to 100 times the capacity, a similar increase in speed and just a fifth of the lag. Like a UK parallel, though, there's only so much technology talk the Commission can offer at this stage. The funding is as much for regional pride as progress -- officials want 5G to be a Europe-led affair after Asia and North America took center stage on 4G.

SACRAMENTO, Calif. (AP) ? Two female California state lawmakers have condemned Oscar host Seth MacFarlane's comments during Sunday's awards presentation as degrading toward women and asked the Academy of Motion Picture Arts and Sciences to use better judgment in the future.
Assemblywoman Bonnie Lowenthal and Sen. Hannah-Beth Jackson, both Democrats who lead the Legislature's women's caucus, sent a letter to Academy President Hawk Koch on Tuesday, requesting that the organization disavow MacFarlane's behavior.
They objected to the comedian's focus on the physical appearance of several actresses and quips about nude scenes.
"Furthermore, there was a disturbing theme about violence against women being acceptable and funny," the lawmakers wrote. "From topical jabs about domestic violence to singing about 'boobs' during a film's rape scene, Seth MacFarlane crossed the line from humor to misogyny."
MacFarlane's performance has drawn multiple critics since Sunday's show. Blogs compiled highlights of his punch lines, which included a song that referenced leading ladies who have bared their breasts on film that were accompanied by reaction shots from those actresses.
He also made light of a domestic violence incident between rapper Chris Brown and singer Rihanna, and joked about the heavy accents of several Latina actresses.
"On Oscar night, when Hollywood seeks to honor its best, Seth MacFarlane's monologue reduced our finest female actresses to caricatures and stereotypes, degrading women as a whole and the filmmaking industry itself," the letter stated.
Lowenthal and Jackson, both Democrats, asked Koch to respond. Academy spokeswoman Toni Thompson had no immediate comment.
In their letter, the lawmakers noted the Violence Against Women Act currently under debate in Congress and a resolution that the Legislature passed supporting the act's reauthorization. Better judgment is needed in the academy's future decisions regarding its awards show hosts and their material, they said.
"This should be a celebration of artists in the filmmaking industry, not an offensive display of disrespect toward women that sets the fight for gender equality, dignity, and respect back decades," they wrote.
A repeat hosting performance by MacFarlane doesn't look likely. Asked Tuesday on Twitter if he would host the Oscars again, he replied, "No way. Lotta fun to have done it, though."

Rick Springfield returning to 'General Hospital'
Chris Pizzello / AP
Rick Springfield's Dr. Drake is returning to "GH"!
By Drusilla Moorhouse, TODAY contributor
For fans of Rick Springfield, this is just what the doctor ordered: The "Jessie's Girl" singer is returning to "General Hospital," reprising his role as Dr. Noah Drake.
Even better, reports People, he'll be joined by his son, Liam Springthorpe. (Springfield was born Richard Springthorpe.) The young actor-musician, who will play an undercover cop, isn't expecting to share scenes with his famous father.
Springfield debuted on the ABC soap opera in 1981 -- the same year "Jessie's Girl" topped the charts and earned him a Grammy award for best male rock vocal performance. Since we last saw Noah Drake in March 2012, Springfield says the good doctor has been "going to Doctors Without Borders and going around the world helping people."
"He lost his wife and became a drunk and regretted all these terrible, sinful ways and then cleaned his act up when he almost died from the alcohol," Springfield told People about the troubled neurosurgeon.
Noah Drake returns to Port Charles in April 2013.
"General Hospital" airs at 1 p.m. PT / 2 p.m. ET weekdays on ABC.

Why Even Art Teachers Have a Problem With Standardized Testing
Gray is the color between black and white and it can be created in many ways. There is cool gray and there is warm gray. There are light grays and dark grays. The question is, how do I make the right gray? Do I add one percent black to white or 99 percent white to black?
As an art teacher, I can give my students a written test to see if they remember the formula, or I can give them a paintbrush and paint.
Standardized tests are supposed to be more acceptable than non-standardized tests. They are created to gather data about answers to predetermined questions in order to determine the students? performance and intelligence. In art education, it is not so simple to measure the creative process, performance and aesthetic responses in student learning.
I am not concerned about the percent of colors my students use to make gray. I am concerned whether or not they understand the technique and can demonstrate it correctly.
Standardized testing does not relate to my ability to teach art better. In fact, there is no standardized testing in visual art. Does this make me less knowledgeable about my subject? Do I have to give my students a standardized test to prove they can make gray paint? How do you compare the artistic ability of Leonardo da Vinci to Jackson Pollock??
The National Art Education Association said it best, ?Assessment is ongoing; formative; performance-based; and designed to assess students? critical thinking and art making skills, creativity, and content knowledge.?
Because I teach at a vocational high school and am considered a Career Technical Educator (CTE), my job is to teach real life skills to prepare students for success in their future. When I walk into my classroom, I know that I?m giving my students the workplace readiness skills they need based upon my experience in working in the field as a professional artist.
As an art educator, I?m fortunate I don?t feel pressure to ?teach to the test.? While my curriculum is not based on preparing students for a state-mandated test, I do have to focus on measuring their learning. There are times when I do give my students written tests based on practical skills to make sure they understand the lesson. However, this is not the only source of assessment, nor is it standard.
There are many ways to teach someone how to paint, and that assessment should be based on students? knowledge, attitude, and performance.
There is a lot of emphasis placed on subjects that are measured on state standardized tests. Unfortunately, standardized testing is often deemed the end all in education. Non-academic subjects, like art, are being cut and teachers? jobs eliminated because school districts focus on standardized test scores as the only source of assessment for student growth.
Student improvement should not be confined to a single score on a standardized test.
I would encourage schools, teachers, and parents to focus on real student learning and on what students are able to produce, not on how well they fill in bubbles on paper with a number two pencil.
Does a student?s ability to answer a series of questions correctly actually indicate proficiency?
I enter my classroom with enthusiasm knowing that I not only teach my students how to paint a self-portrait using Chuck Close style, but I also know I am giving them freedom to use the right side of their brain and give the left side a rest.?
Student improvement should not be confined to a single score on a standardized test. I know a students? classroom performance on how they think and perform a task are factors of authentic learning. Students must be challenged to understand integrated forms of knowledge, not just the memorization of terms.

Group: Syrian regime missiles kill 140 in Aleppo
BEIRUT (AP) ? At least 141 people, half of them children, were killed when the Syrian military fired at least four missiles into the northern city of Aleppo last week, Human Rights Watch confirmed Tuesday after a researcher visited the area.
The international rights group said the strikes hit residential areas and called them an "escalation of unlawful attacks against Syria's civilian population."
Aleppo, Syria's largest city, has been the scene of some of the heaviest fighting of the civil war pitting President Bashar Assad's regime against rebels fighting to oust him.
Rebels quickly seized several neighborhoods in an offensive on the city in July, but the government still controls some districts and the battle has developed into a bloody stalemate, with heavy street fighting that has ruined neighborhoods and forced thousands to flee.
A Human Rights Watch researcher who visited Aleppo last week to inspect the targeted sites, said up to 20 buildings were destroyed in each area hit by a missile. There were no signs of any military targets in the residential districts, located in rebel-held parts of Aleppo, said Ole Solvang, the HRW's researcher.
"Just when you think things can't get any worse, the Syrian government finds ways to escalate its killing tactics," Solvang said.
Human rights watch said 71 children were among the 141 people killed in the four missile strikes on three opposition-controlled neighborhoods in eastern Aleppo. It listed the names of the targeted neighborhoods as Jabal Badro, Tariq al-Bab and Ard al-Hamra. The fourth strike documented by the group was in Tel Rifat, north of Aleppo.
"The extent of the damage from a single strike, the lack of (military) aircraft in the area at the time, and reports of ballistic missiles being launched from a military base near Damascus overwhelmingly suggest that government forces struck these areas with ballistic missiles," the report said.
Syrian anti-regime activists first reported the attacks last week, saying they involved ground-to-ground missiles, and killed dozens of people. The reports could not be independently confirmed because Syrian authorities severely restrict access to media.
Human Rights Watch said it compiled a list of those killed in the missile strikes from cemetery burial records, interviews with relatives and neighbors, and information from the Aleppo Media Center and the Violations Documentation Center, a network of local activists.
The rebels control large swaths of land in northeastern Syria. In recent weeks, Assad's regime has lost control of several sites with key infrastructure in that part of the country, including a hydroelectric dam, a major oil field and two army bases along the road linking Aleppo with the airport to its east.
A key focus for the rebels in the Aleppo area is to capture the city's international airport, which the opposition fighters have been attacking for weeks.
Opposition forces have also been hitting the heart of Damascus with occasional mortars shells or bombings, posing a stiff challenge to the regime in its seat of power.
U.S. and NATO officials have previously said that Syria has a significant ballistic missile capability and is believed to have a few hundred missiles with a range of some 700 kilometers (440 miles) that could hit targets deep inside Turkey, a NATO member and one of the harshest critics of the Assad regime.
NATO has in recent weeks deployed Patriot missile systems along Turkey's border with Syria.
The missile attacks have outraged the leaders of the exiled opposition who have accused their Western backers of indifference to the suffering of the Syrian people.

Start-up Of The Week: Catmoji - A Cool Social Network For Cat Lovers
When we first featured Catmoji on our blog, little did we know that it would soon become the talk of the town (especially, among the cats... they are all meowing at it!)?Jokes apart, there are so many social networking and photo-bookmarking websites on the internet but what makes Catmoji stand out from the rest is the fact that it's?a social network exclusively for cat?lovers.
4. What inspired you guys to open a Catmoji shop on Society6? Have you considered selling directly through your own website? With the limited resources we have, Society6 is a no-brainer because it does a lot of heavy lifting for us (printing, shipping, payment, etc). In the future, we do want to have our own shop.
6. How are you guys promoting Catmoji? What do you think is the ideal mix of social, online and offline promotion? What about word-of-mouth promotion? Currently, most of the buzz are generated by our users and visitors and yes word-of-mouth through social media. On our side, we use mainly Twitter and Facebook to promote Catmoji. Offline promotion? We never thought of that, maybe in the future.
Developed by two huge cat lovers, Matthew Phiong and Koekoe Loo, Catmoji is a platform for cat lovers where they can share and discover images and videos of cats, and express what they think or feel through emoji.
According to the website, "Catmoji is on a mission to make the internet a better and happier place with cats. Join and help us disrupt the Internet with cats and happiness".
Catmoji is a user-friendly website and is specifically designed for cat lovers. At first, it might look Pinterest-like because of its layout but once you create your profile and get a hang of it, you'll realize the difference.
Catmoji is all about cats, you just have to upload content or re-share already uploaded content by other users. Other users can follow you back, like or re-share your content and comment on it. Based on your activity on Catmoji you can unlock different yet addictive?Catsome badges.
Catmoji is one fab website for cat lovers and owners and in case, you're not a cat person I bet you'll fall in love with cats once you visit Catmoji.?Read on to know more about Catmoji in our exclusive interview with its founder.
1. Hi Matt and Koekoe, please introduce yourselves to our readers.
Hey! We are the founders of Catmoji. Matt is the geeky programmer and Koekoe is the funky designer.
2. What is Catmoji? What inspired you guys to come up with it? Curious about the etymology of your website?s name. Why a website just for cat lovers?
Catmoji is a social network for cats where cat owners and lovers can share and discover cat pictures and videos through emoji.
We had this idea while working on our previous project, Flvrd (Flvrd is a place that lets people share and discover interesting visual content (pictures and videos) based on their tastes). Many of the content shared on Flvrd are cat pictures and videos and that gives us the initial spark. That is how Catmoji was born.
Catmoji is simply the combination of Cat + Emoji.
Well, we found out that there is no one place on the Internet that allows us to easily share and collect cat pictures and videos. Cat owners and lovers share cat pictures and videos all over the Internet from Instagram to Flickr to Youtube and also on social media site like Facebook and Twitter. Plus, the Internet loves cats :)
3. How is Catmoji different from let?s say creating different boards on Pinterest? What differentiates Catmoji from Pinterest? Although a lot of people visually compared us to Pinterest, we build Catmoji specifically for cat lovers from the design to features. For example, every user on Catmoji has a Catvatar associated to their profile.4. What inspired you guys to open a Catmoji shop on Society6? Have you considered selling directly through your own website? With the limited resources we have, Society6 is a no-brainer because it does a lot of heavy lifting for us (printing, shipping, payment, etc). In the future, we do want to have our own shop.
5. What are these Catvatars and the Catsome Badges?
Catvatar (Cat avatar) basically is a visual representation of cat breeds or cat lover's alter ego. Catsome Badges are cat-based badges that users can unlock on Catmoji.
6. How are you guys promoting Catmoji? What do you think is the ideal mix of social, online and offline promotion? What about word-of-mouth promotion? Currently, most of the buzz are generated by our users and visitors and yes word-of-mouth through social media. On our side, we use mainly Twitter and Facebook to promote Catmoji. Offline promotion? We never thought of that, maybe in the future.
7. What sort of traction are you guys seeing as far as members is concerned? Could you share the median age of userbase? What is the biggest compliment that you have received for creating the website?
We have just passed 12,000 users last week and the median age is around 30 years old.
Tons of love messages from all around the world from Facebook messages to tweets and emails. Best part is they all came in different languages (Russian, Spanish, Italian and Japanese to name a few) and we had to use Google Translate for that.
8. What is the fondest memory that the two of you have of the process, from conceiving Catmoji to having it up and running ? What issues/difficulties did you face initially?
Going viral. We never expected this to happen and if it doesn't, we might not be having this interview with you.
Initially, Catmoji had a lot of bugs and expectedly so. Also, our servers were pushed to the limit and crashed frequently when Catmoji went viral.
9. What sort of activities do you guys like to pursue in your free time? Which of these do you find to be most de-stressing??
We love to play games on iPad, watch cat pictures and videos, and chill out with cats in our neighborhood. Most de-stressing one? Definitely chilling out with cats.
10. If both of you could have one superhero (or magical) power each, what would it be and why?
Matt: Power that can keep me awake all day long so I don't have to waste time sleeping :)
Koekoe: Being able to converse with dogs as if I'm chatting with real human. It will be fuuuun.
11. What are your future plans for Catmoji? Any new feature(s)/enhancement(s) in the pipeline?
We constantly improving and enhancing Catmoji based on the feedback and suggestions we get from our users. There should be a search feature soon and we are currently working on an iPhone app. Stay tuned!
Thank you Matt and Koekoe for taking out the time and doing this interview with us. We'd like to wish you both and your team at Catmoji the very best for the future.
Well, currently you can only sign-up with Catmoji by requesting for an invite but since the founders of Catmoji are way too kind, they decided to provide our readers a special invite code so that they can easily sign-up using this link -?http://catmoji.com/join/ejunkie/. Keep in mind that this link is only valid for the first 500 readers.

Climatic and tectonic controls on sedimentation and erosion during the Pliocene-Quaternary in Qaidam Basin (China)
Richard V. Heermance et al., Dept. of Geological Sciences, California State University-Northridge, Northridge, California 91330-8266, USA. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30748.1.
The Pliocene-Quaternary boundary, approx. 2.6 million years ago (2.6 Ma), represents a time of rapid global climate change from warm and moist to cool and arid (i.e., glacial) conditions. The influence of this climate change on both sedimentation and tectonics is preserved in strata within the Qaidam Basin, China. Overall, climate-controlled basin aridification initiated 3.1 million years ago and caused the gradual change from more humid lacustrine sedimentation to evaporite conditions by 2.6 Ma. After 2.6 Ma, uplift above active structures combined with wind erosion of the basin sediments produced localized sediment traps that controlled sedimentation. This study provides isotopic (O and C), paleomagnetic, and sedimentologic data that distinguish the climatic versus tectonic controls on sedimentation and erosion within the northeastern Tibetan Plateau at this important time period.
Variation of climate and long-term erosion rates across a steep rainfall gradient on the Hawaiian island of Kauai
Ken L. Ferrier et al., Dept. of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, 77 Massachusetts Avenue, Cambridge, Massachusetts 02139-4307, USA. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30726.1.
The erosion of volcanic ocean islands creates dramatic landscapes, modulates Earth's carbon cycle, and delivers sediment to coasts and reefs. Despite concerns that modern sediment fluxes to island coasts may exceed long-term fluxes, little is known about how erosion rates and processes vary across island interiors. This study by Ken L. Ferrier and colleagues presents new measurements of erosion rates over five-year to five-million-year time scales on the Hawaiian island of Kauai, which is home to one of Earth's steepest precipitation gradients, with mean annual precipitation ranging from 0.5 to 9.5 m. Eroded rock volumes from basins across Kauai indicate that basin-averaged erosion rates over the past several million years vary by a factor of 40 across the island and increase with modern mean annual precipitation. In the Hanalei basin of Kauai, estimates of sediment fluxes and solute fluxes imply that modern erosion rates are no more than 2.3 plus or minus 0.6 times faster than erosion rates over the past few thousand years, as determined by new measurements of helium-3 in olivines in stream sediment. To the extent that modern precipitation patterns resemble long-term precipitation patterns, these measurements provide new support for a link between precipitation rates and long-term basin-averaged erosion rates.
Sedimentological constraints on the evolution of the Cordilleran arc: New insights from the Sonsela Member, Upper Triassic Chinle Formation, Petrified Forest National Park (Arizona, USA)
Evan R. Howell, Noble Energy, 1625 Broadway, Suite 2200, Denver, CO 80202, USA; and Ronald C. Blakey. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30714.1.
The Sonsela Member of the Upper Triassic Chinle Formation in Petrified Forest National Park, Arizona, USA, forms a distinctive part of an extensive ancient river system that once flowed, at least in part, from a major volcanic arc bordering the western margin of North America (Cordilleran magmatic arc). The Sonsela Member is characterized as a relatively coarse-grained unit compared to other mudstone-dominated members of the Chinle Formation, and is therefore thought to reflect a unique period in the evolution of the basin. Modern exposures of the Cordilleran arc are poorly preserved, the result of subsequent tectonic deformation, erosion, and sedimentation in western North America since the Late Triassic. Sedimentary sequences of the Chinle Formation, however (particularly those of the Sonsela Member), preserve the dynamic evolution of the basin as the volcanic arc was established in southwestern North America. The Sonsela Member therefore serves as the most reliable indicator of fluctuations in arc dynamics of a poorly preserved and disjointed portion of the Cordilleran magmatic arc.
Neotectonic faulting and forearc sliver motion along the Atirro-Ro Sucio fault system, Costa Rica, Central America
Walter Montero P. et al., Geological Sciences Research Center, University of Costa Rica, San Jos, Costa Rica; Corresponding author: Sarah Kruse, Dept. of Geology, University of South Florida, Tampa, Florida 33620, USA. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30471.1.
Two important questions about the Cocos-Caribbean subduction zone of Costa Rica are how trench-parallel forearc motion is accommodated and what drives forearc sliver motion. This work by Walter Montero P. and colleagues provides critical constraints on the former and lays the foundation for exploring the latter. It documents a network of northwest-striking right-lateral strike slip faults that appears to mark the northern boundary of an upper-plate sliver moving NW relative to the Caribbean plate. Despite high erosion rates and deep weathering, the fault system includes pull-apart basins with preserved normal fault scarps and tilted hanging-wall buttress unconformities, pressure ridges, displaced and beheaded drainages, sag ponds, and fault-controlled upland valleys. Montero and colleagues integrate geomorphic observations with outcrop-scale bedrock fault kinematic and earthquake focal mechanism data to map the active through-going fault zone. The mapping reveals that the fault system traverses the active volcanic arc from NW to SE and connects to an area of high uplift rate in the inactive Talamanca magmatic arc, where the faults are interpreted to originate inboard of the actively colliding Cocos ridge. This suggests that, kinematically, the forearc sliver is rooted in the collision zone.
Mesozoic fault reactivation along the St. Lawrence rift system, eastern Canada: Thermochronologic evidence from apatite fission-track dating
Alain Tremblay et al., Dpartement des Sciences de la Terre et de l'Atmosphre and GEOTOP, Universit du Qubec. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30703.1.
The St. Lawrence rift system is formed by a series of northeast-southwest-trending faults in southeastern Qubec that links and includes the northwest-trending Ottawa-Bonnechre and Saguenay River regions. It is an active fault zone where reactivation of Late Precambrian (less than one billion years ago) faults, at times as young as post-Late Devonian (350 million years ago), is believed to occur. Apatite fission-track (AFT) ages, which represent the time that the rocks cooled through 100 degrees Celsius (3-4 km depth) on their way to the surface, have been determined for Late Precambrian rocks from both sides of typical rift faults at different locations in the St. Lawrence and Saguenay river fault systems along the St. Lawrence rift system. Differences in AFT ages were found across all the faults studied, suggesting reactivation of extensional movement approx. 250-200 million years. Along the St. Lawrence River fault system, the AFT ages also suggest a renewal of movement in a compressional sense at ca. 150 Ma. This study provides evidence for extension related to rifting in the Atlantic Ocean followed by compressional deformation in the interior of Canada, more than 500 km west of the Atlantic coastal margin.
Chemical and ecological evolution of the Miocene Ries impact crater lake, Germany: A reinterpretation based on the Enkingen (SUBO 18) drill core
Gernot Arp et al., Georg-August-Universitt Gttingen, Geowissenschaftliches Zentrum, Goldschmidtstrasse 3, 37077 Gttingen, Germany. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30731.1.
Impact crater lakes potentially form valuable climatologic archives. The lacustrine succession of the 15-million-year-old Ries Crater Lake has previously been interpreted as climate-controlled development from a playa to a highly saline soda lake, which successively decreased in salinity to reach freshwater sedimentation with temporary coal swamps. New multidisciplinary investigations based on a partial section now question this view: The sediments of this new drill core reflect increasing, not decreasing salinities, with brown coals formed by plant debris swept into a hypersaline setting. In addition, the chemical composition of the inflowing waters changed due to the weathering of different ejecta layers in the catchment area. Interpolated to the whole succession, a new model for the Ries Crater Lake is developed: After the development of a brackish soda lake and erosion of the upper ejecta blanket (suevite), an increasing ion influx from the lower ejecta (Bunte Breccia) caused a change to a marine-like, and finally hypersaline salt lake. Therefore, intrinsic factors, such as weathering history in the catchment area, probably dominated over external, climatic factors with respect to the chemical and ecological evolution of this impact crater lake. Moreover, the initial suevite blanket might have been more widespread than previously assumed.
Oroclines: Thick and thin
S.T. Johnston et al., School of Earth & Ocean Sciences, University of Victoria, PO Box 3065 STN CSC, Victoria British Columbia, Canada V8P 4B2. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30765.1.
Folded rocks characterize young and old mountain belts the world over, and form some of the most familiar and spectacular of geological structures. But can you fold an entire mountain belt? Stephen Johnston of the University of Victoria and his colleagues Arlo Weil of Bryn Mawr University and Gabriel Gutierrez-Alonso of the University of Salamanca have been studying the geometry of mountain belts, and their findings, summarized in this review paper, suggest that not only can you bend a mountain belt, but that folds of mountain belts, referred to as oroclines, constitute the largest geological structures on Earth. Based on an extensive compilation of geological and geophysical data, they demonstrate that during the development of a mountain chain, minor bends of faults and folds can develop, but that subsequently the entire mountain chain can be buckled into one or more oroclines. For example, the 320-million-year-old Variscan Mountain chain of Iberia, which formed during the continental collisions that gave rise to Pangea, subsequently buckled giving rise to two coupled oroclines. During buckling, a 2,300-km-long, 300-km-wide, linear mountain chain was shortened by more than 1,100 km, giving rise to two of Earth's largest folds and forming the Iberian Peninsula. These findings suggest that the buckling of mountain chains is an important process responsible for the development and growth of continents.
Deriving a long paleoseismic record from a shallow-water Holocene basin next to the Alpine fault, New Zealand
K.J. Clark et al., GNS Science, PO Box 30368, Lower Hutt, New Zealand. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30693.1.
Scientists have investigated evidence left by large surface-rupturing earthquakes on the Alpine Fault in New Zealand over an 8,000 year period. The earthquakes left "geological signatures" of alternating peat and silt in the exposed banks of Hokuri Creek, an isolated creek in northern Fiordland. Detailed mapping, sedimentology and microfossil analysis were used to investigate the relationship between sediment deposition and Alpine fault rupture at Hokuri Creek. Repeated fault rupture involving a component of vertical movement is shown to be the most convincing mechanism for explaining the cyclical peat and silt sedimentary sequence. This article by K.J. Clark and colleagues delves into the detail of how a record of 22 earthquakes between circa AD 800 to 6000 BC was obtained. The Hokuri Creek sequence represents one of the longest continuous large earthquake records of any on-land plate boundary fault in the world. The Alpine Fault extends about 600 km along the spine of the South Island between Milford Sound and Marlborough. It last ruptured in 1717 AD producing an earthquake of approx. magnitude 8.
Paleogene postcompressional intermontane basin evolution along the frontal Cordilleran fold-and-thrust belt of southwestern Montana
Theresa M. Schwartz and Robert K. Schwartz, Geological and Environmental Sciences, Stanford University, 450 Serra Mall, Bldg. 320, Stanford, California 94305, USA. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30776.1.
This article by Theresa M. Schwartz and Robert K. Schwartz investigates the evolution of the Montana landscape between approximately 50 and 20 million years ago. Detailed examination of the depositional facies and provenance of the Renova Formation in southwestern Montana provides important insight into the physical processes that affected the eastern part of the North American Cordillera after it became inactive. These include the interplay between tectonism (both in the crust and deeper in the lithosphere), erosion on the surface by large river systems, and shifts in climate patterns. Ultimately, this study finds that the complex structure that was generated more than 50 million years ago exerted and continues to exert strong controls on the landscape, dictating areas of erosion and deposition.

The Sonsela Member is characterized as a relatively coarse-grained unit compared to other mudstone-dominated members of the Chinle Formation, and is therefore thought to reflect a unique period in the evolution of the basin. Modern exposures of the Cordilleran arc are poorly preserved, the result of subsequent tectonic deformation, erosion, and sedimentation in western North America since the Late Triassic. Sedimentary sequences of the Chinle Formation, however (particularly those of the Sonsela Member), preserve the dynamic evolution of the basin as the volcanic arc was established in southwestern North America. The Sonsela Member therefore serves as the most reliable indicator of fluctuations in arc dynamics of a poorly preserved and disjointed portion of the Cordilleran magmatic arc.
Neotectonic faulting and forearc sliver motion along the Atirro-Ro Sucio fault system, Costa Rica, Central America
Walter Montero P. et al., Geological Sciences Research Center, University of Costa Rica, San Jos, Costa Rica; Corresponding author: Sarah Kruse, Dept. of Geology, University of South Florida, Tampa, Florida 33620, USA. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30471.1.
Two important questions about the Cocos-Caribbean subduction zone of Costa Rica are how trench-parallel forearc motion is accommodated and what drives forearc sliver motion. This work by Walter Montero P. and colleagues provides critical constraints on the former and lays the foundation for exploring the latter. It documents a network of northwest-striking right-lateral strike slip faults that appears to mark the northern boundary of an upper-plate sliver moving NW relative to the Caribbean plate. Despite high erosion rates and deep weathering, the fault system includes pull-apart basins with preserved normal fault scarps and tilted hanging-wall buttress unconformities, pressure ridges, displaced and beheaded drainages, sag ponds, and fault-controlled upland valleys. Montero and colleagues integrate geomorphic observations with outcrop-scale bedrock fault kinematic and earthquake focal mechanism data to map the active through-going fault zone. The mapping reveals that the fault system traverses the active volcanic arc from NW to SE and connects to an area of high uplift rate in the inactive Talamanca magmatic arc, where the faults are interpreted to originate inboard of the actively colliding Cocos ridge. This suggests that, kinematically, the forearc sliver is rooted in the collision zone.
Mesozoic fault reactivation along the St. Lawrence rift system, eastern Canada: Thermochronologic evidence from apatite fission-track dating
Alain Tremblay et al., Dpartement des Sciences de la Terre et de l'Atmosphre and GEOTOP, Universit du Qubec. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30703.1.
The St. Lawrence rift system is formed by a series of northeast-southwest-trending faults in southeastern Qubec that links and includes the northwest-trending Ottawa-Bonnechre and Saguenay River regions. It is an active fault zone where reactivation of Late Precambrian (less than one billion years ago) faults, at times as young as post-Late Devonian (350 million years ago), is believed to occur. Apatite fission-track (AFT) ages, which represent the time that the rocks cooled through 100 degrees Celsius (3-4 km depth) on their way to the surface, have been determined for Late Precambrian rocks from both sides of typical rift faults at different locations in the St. Lawrence and Saguenay river fault systems along the St. Lawrence rift system. Differences in AFT ages were found across all the faults studied, suggesting reactivation of extensional movement approx. 250-200 million years. Along the St. Lawrence River fault system, the AFT ages also suggest a renewal of movement in a compressional sense at ca. 150 Ma. This study provides evidence for extension related to rifting in the Atlantic Ocean followed by compressional deformation in the interior of Canada, more than 500 km west of the Atlantic coastal margin.
Chemical and ecological evolution of the Miocene Ries impact crater lake, Germany: A reinterpretation based on the Enkingen (SUBO 18) drill core
Gernot Arp et al., Georg-August-Universitt Gttingen, Geowissenschaftliches Zentrum, Goldschmidtstrasse 3, 37077 Gttingen, Germany. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30731.1.
Impact crater lakes potentially form valuable climatologic archives. The lacustrine succession of the 15-million-year-old Ries Crater Lake has previously been interpreted as climate-controlled development from a playa to a highly saline soda lake, which successively decreased in salinity to reach freshwater sedimentation with temporary coal swamps. New multidisciplinary investigations based on a partial section now question this view: The sediments of this new drill core reflect increasing, not decreasing salinities, with brown coals formed by plant debris swept into a hypersaline setting. In addition, the chemical composition of the inflowing waters changed due to the weathering of different ejecta layers in the catchment area. Interpolated to the whole succession, a new model for the Ries Crater Lake is developed: After the development of a brackish soda lake and erosion of the upper ejecta blanket (suevite), an increasing ion influx from the lower ejecta (Bunte Breccia) caused a change to a marine-like, and finally hypersaline salt lake. Therefore, intrinsic factors, such as weathering history in the catchment area, probably dominated over external, climatic factors with respect to the chemical and ecological evolution of this impact crater lake. Moreover, the initial suevite blanket might have been more widespread than previously assumed.
Oroclines: Thick and thin
S.T. Johnston et al., School of Earth & Ocean Sciences, University of Victoria, PO Box 3065 STN CSC, Victoria British Columbia, Canada V8P 4B2. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30765.1.
Folded rocks characterize young and old mountain belts the world over, and form some of the most familiar and spectacular of geological structures. But can you fold an entire mountain belt? Stephen Johnston of the University of Victoria and his colleagues Arlo Weil of Bryn Mawr University and Gabriel Gutierrez-Alonso of the University of Salamanca have been studying the geometry of mountain belts, and their findings, summarized in this review paper, suggest that not only can you bend a mountain belt, but that folds of mountain belts, referred to as oroclines, constitute the largest geological structures on Earth. Based on an extensive compilation of geological and geophysical data, they demonstrate that during the development of a mountain chain, minor bends of faults and folds can develop, but that subsequently the entire mountain chain can be buckled into one or more oroclines. For example, the 320-million-year-old Variscan Mountain chain of Iberia, which formed during the continental collisions that gave rise to Pangea, subsequently buckled giving rise to two coupled oroclines. During buckling, a 2,300-km-long, 300-km-wide, linear mountain chain was shortened by more than 1,100 km, giving rise to two of Earth's largest folds and forming the Iberian Peninsula. These findings suggest that the buckling of mountain chains is an important process responsible for the development and growth of continents.
Deriving a long paleoseismic record from a shallow-water Holocene basin next to the Alpine fault, New Zealand
K.J. Clark et al., GNS Science, PO Box 30368, Lower Hutt, New Zealand. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30693.1.
Scientists have investigated evidence left by large surface-rupturing earthquakes on the Alpine Fault in New Zealand over an 8,000 year period. The earthquakes left "geological signatures" of alternating peat and silt in the exposed banks of Hokuri Creek, an isolated creek in northern Fiordland. Detailed mapping, sedimentology and microfossil analysis were used to investigate the relationship between sediment deposition and Alpine fault rupture at Hokuri Creek. Repeated fault rupture involving a component of vertical movement is shown to be the most convincing mechanism for explaining the cyclical peat and silt sedimentary sequence. This article by K.J. Clark and colleagues delves into the detail of how a record of 22 earthquakes between circa AD 800 to 6000 BC was obtained. The Hokuri Creek sequence represents one of the longest continuous large earthquake records of any on-land plate boundary fault in the world. The Alpine Fault extends about 600 km along the spine of the South Island between Milford Sound and Marlborough. It last ruptured in 1717 AD producing an earthquake of approx. magnitude 8.
Paleogene postcompressional intermontane basin evolution along the frontal Cordilleran fold-and-thrust belt of southwestern Montana
Theresa M. Schwartz and Robert K. Schwartz, Geological and Environmental Sciences, Stanford University, 450 Serra Mall, Bldg. 320, Stanford, California 94305, USA. Posted online 22 Feb. 2013; http://dx.doi.org/10.1130/B30776.1.
This article by Theresa M. Schwartz and Robert K. Schwartz investigates the evolution of the Montana landscape between approximately 50 and 20 million years ago. Detailed examination of the depositional facies and provenance of the Renova Formation in southwestern Montana provides important insight into the physical processes that affected the eastern part of the North American Cordillera after it became inactive. These include the interplay between tectonism (both in the crust and deeper in the lithosphere), erosion on the surface by large river systems, and shifts in climate patterns. Ultimately, this study finds that the complex structure that was generated more than 50 million years ago exerted and continues to exert strong controls on the landscape, dictating areas of erosion and deposition.
