The original paper that proposed Bitcoin is credited to a "Satoshi Nakamoto."
It was widely assumed to be a pseudonym for the team of coders behind the virtual currency.
But then, came this - a blockbuster Newsweek cover story, written by Leah McGrath Goodman, that names Dorian Satoshi Nakamoto as "the mystery man behind the crypto-currency."
The report has generated a lot of controversy, especially among members of the Bitcoin community who say the evidence is insufficient and circumstantial.
And since the revelation, Mr. Nakamoto himself has denied any link to the virtual currency.
So is he truly the brains behind Bitcoin?
That was the first question I posed to Newsweek's Leah McGrath Goodman…
There is shock and outrage in Hong Kong after the brutal stabbing of a veteran newspaper editor.
Kevin Lau, a journalist in Hong Kong known for his tough reporting on China, is fighting for his life after a knife attack by an unknown assailant.
Last month, Lau was sacked as the editor of the Ming Pao newspaper, stirring public outcry about press freedom in Hong Kong.
Many of Lau's supporters feared his departure reflected Beijing's efforts to limit press freedom and influence independent media in semi-autonomous Hong Kong.
After the knife attack, Hong Kong Chief Executive C.Y. Leung was quick to condemn the violence.
Meanwhile, journalists are stunned that such an attack would take place in Hong Kong - an international media hub that has supported free reporting across the political spectrum.
Click on to hear the concerned reaction from journalist Tara Joseph, the President of the Foreign Correspondents' Club in Hong Kong.
Samsung's latest flagship smartphone is out. The reviews are in. And the reaction is...
"What you're seeing here is a Samsung that's very much on cruise control," says Chris Ziegler, deputy managing editor of The Verge.
"It's an evolution of the S4, not a whole new phone. There were some of us who were hoping they would take a little bit of a leap here, go to an aluminum body, maybe a new user interface, but really it's just an evolved S4."
Compared to its predecessor, the S5 has a bigger screen, a better camera and a faster processor.
There's also a fingerprint sensor built into the home button, just like what you find in the iPhone 5s.
But one big change in the Galaxy S5: there's a built-in heart rate sensor. Does that score points for Samsung?
"The fact that they included a heart rate sensor in the GS5 really isn't surprising when you consider fitness is a buzzword in mobile now," Ziegler tells me.
Along with the Galaxy S5, Samsung unveiled three smartwatches at the Mobile World Congress – the Samsung Gear 2, the Gear 2 Neo, and the Gear Fit.
For Ziegler and his fellow editors at the Verge, the slender and form-fitting Gear Fit stole the limelight at the big reveal in Barcelona.
"Of the new smartwatches that they showed yesterday, that would be the winner for sure," says Ziegler.

So Facebook purchases the mobile messaging service WhatsApp for $19 billion in cash and stock.
And the world raises a collective eyebrow.
Yes, the app has over 450 million monthly active users. But is it truly worth it?
According to Silicon Valley insider Om Malik, the answer is yes... if you're Mark Zuckerberg.
Malik tells me, "What seems like an insane amount of money is not insane when you feel a little worried about the long-term prospects of the company."
Click on to hear more about why Facebook forked up so much money for WhatsApp, and to see how the app's key metrics compare to its rivals.
You might not worry a lot about cybersecurity, but it's an issue that affects everyone online.
Militaries and governments see cyberattacks as serious threats.
Businesses and individuals can be impacted by data theft. In fact, just last month, 20 million South Koreans had their personal data stolen in a colossal breach.
Why is this happening? And how can we protect ourselves?
I recently spoke with P.W. Singer, Director of The Center for 21st Century Security and Intelligence at the Brookings Institution. He's also co-author of the newly released book, "Cybersecurity and Cyberwar: What everyone needs to know."
Singer says one factor behind the wave of recent major data breaches is something he calls the "Cybersecurity Knowledge Gap." It refers to political and business leaders tasked with managing cybersecurity but are themselves not cyber-literate.
"This gap is across the board," says Singer." And it's because we have an attitude that - as one White House official said - this is a domain 'only for the nerds.'"
"But we're all on cyberspace, we all depend on it, so we can't treat it as an issue for the I.T. crowd."
"We teach our kids regular hygiene not just to protect themselves but everyone else they connect with during the day," he says.
"We need the same attitude when it comes to cyber hygiene and our collective responsibility at the global level all the way down to individual citizens and netizens."
It may start with updating your password or upgrading your firewall - just one step forward and away from an age of rising cyber insecurity.
Nintendo is in trouble.
It's hard to disagree with that after it slashed its forecast for Wii U sales from 9 million to just 2.8 million. Less dramatic but perhaps just as troubling: It also cut its forecast for its market-leading 3DS handheld. Nintendo now expects to sell 13.5 million of them, down from the 18 million they originally expected.
But what's up for debate is how Nintendo can climb out of this hole. By far the most common solution suggested: Nintendo should put games like Mario and Zelda on smartphones and tablets.
Just last month in Beijing, U.S. Vice President Joe Biden lamented the lack of press freedom in China.
Despite such high-profile criticism, Beijing has increased its pressure on foreign correspondents in China.
China is refusing to renew a visa for New York Times reporter Austin Ramzy, the second Times reporter in 13 months to be forced out of the country.
Is the visa holdup payback for critical coverage of China's political elite?
"It will certainly feed suspicion that it's retribution for the content of their coverage," says Peter Ford, President of the Foreign Correspondents' Club of China and Beijing Bureau Chief for the Christian Science Monitor.
For more on the various ways China is putting the pressure on foreign correspondents, watch the video report above.
Anyone with an older Mac probably knows this icon: A boxy all-in-one computer with a simple smiling face on screen.
Like all good symbols, the Happy Mac serves multiple purposes. The official reason it exists is to tell you that your Macintosh has begun the process of booting up without error.
More than that, the Happy Mac was a symbol of intent from Apple: This computer is friendly. It doesn't have an impenetrable interface filled with text you don't understand. The Mac has pictures. And it's smiling at you!
Susan Kare was the graphic designer who created the Happy Mac. She spoke to us about the process behind that and many of the other icons that made the original Macintosh so different to any computer before it.
With our planet under pressure from human activity and ecological constraints, noted author and economist Jeffrey Sachs says we have entered - by necessity - "The Age of Sustainable Development."
"We can't just focus on economics alone," says Sachs. "We need to focus on economics, social inclusion... and on environmental sustainability."
Sachs recognizes China's success in ending extreme poverty over the last three decades. And he commends the country for bringing big investment to Africa.
But China has a huge challenge ahead if it wishes to develop sustainably.
"It's done great on economics but on the environment? This is the next challenge," he says.
"China is a coal-based economy and coal is a huge problem for air pollution and carbon dioxide that changes the climate."
Because in the end, prosperity alone isn't enough for the people of China.
"They want happiness and well-being, and that means you can breathe the air and know you have the chance if you are poor that your child can get ahead," says Sachs.
