Besides the Galaxy S 4 announcement yesterday, Samsung also announced a big change in leadership, adding two new CEOs to the company

Presidents Boo-keun Yoon and JK Shin will join current CEO Oh-Hyun Kwon, meaning the company will now have three CEOs

All three CEOs will also retain their current duties: Yoon will stay in charge of Samsung's Consumer Electronics Division, including TV and appliance products; Shin will continue leading the company's IT & Mobile Communications Division, and Kwon will continue to oversee Samsung's component business.

The idea behind the move is to "clarify and enhance independent management" of the three divisions, Samsung explains. With its diverse portfolio of products and services, and a $6.6 billion profit in Q4 2012, it's no wonder that Samsung thinks it's getting too big for just one CEO

There is nothing more frustrating than a perfectly good username gone to waste.

There is a large amount of brands, celebrities and other potentially valuable accounts being taken advantage of on Twitter. Users squat a celebrity or brand name and then assume the account will garner followers on the name alone. Of course, other users are usually smart enough to realize Steve Buscemi is probably not really advertising a website for "Father's Day Gift Ideas." (If anything, the egg avatar will always give it away.)

Twitter as a company is familiar with this annoyance. Its founders originally planned for users to text status updates to Twittr (the former name) using the matching five-digit short code. It turns out the number was already taken by Teen People: "txttp," or "Text TP."

Samsung's new feature-packed Galaxy S 4 smartphone may actually be good for your health.

The new flagship phone, introduced at an event at Radio City Music Hall in New York, has a built-in pedometer and an app called S Health.

The phone has built-in sensors designed to measure the temperature and humidity of your location, which is then sent to the S Health app

"The combination of sensors built within the device systematically and automatically monitors your health, surroundings and so much more to help improve your quality of life," says Samsung

The S Health app will also work with third party devices such as glucose meters and blood pressure monitors.

At a packed event in New York’s Radio City Music Hall Thursday, Samsung revealed its newest flagship smartphone, the Galaxy S 4. Following in the footsteps of the bestselling Android phone on the market, the Galaxy S III, the S 4 sports a number of unique new features, while keeping some favorite options from its predecessor.

A far from ordinary event, the announcement was full of song and dance numbers, some bizarre theater moments, and a few surprises.

A Familiar Look

At first glance, you’d be forgiven for mistaking the Galaxy S 4 for the Galaxy S III. The phone sports a very similar look and feel to its predecessor, in a slightly thinner body, with a slightly larger 5-inch screen. The handset is made entirely of polycarbonate, and will be available in two options: black mist and white frost.

As advances in genomics, molecular analysis, and data processing have propelled disease research forward, scientists and drug developers still face a formidable challenge: recruiting patients for their studies.

Genetic Alliance, a nonprofit that advocates for people with rare genetic disorders, is launching a new site called Reg4All that aims to entice more patients into clinical trials and disease research by giving them unprecedented privacy controls and greater say in how their data is used for research.

Reg4All’s emphasis on privacy controls and patient consent is unique. While many biobanks and DNA databases have participants sign broad consent forms that leave them little control over data, Reg4All allows patients to fine-tune how their information is used—sharing it with particular researchers, institutions, or people studying a specific disease. They will also be able to track who uses their data and how.

It's pretty hard to one-up Justin Timberlake, but Tori Kelly may just have done it.

Her acoustic guitar cover of the pop star's latest single, "Suit & Tie," has a natural and smooth flavor that we're sure even JT would applaud

This isn't the first foray into cover songs for Kelly. Her YouTube page has renditions of Michael Jackson's "PYT" and Frank Ocean's "Thinkin Bout You," among many others

The singer also competed on American Idol's ninth season, but never made it to the finals. She seems to be doing pretty well, regardless — her video has accrued almost a million views in a few days, proving that Kelly is probably headed for stardom

The New York Times is overhauling its article pages as part of its first major website redesign since 2006. The Times released an animated preview on Tuesday, and we stopped by their offices on Wednesday to get a closer look.

The first thing you'll notice about the new article pages — still in prototype phase — is how clean they are. There's a generous amount of white space bordering the text. The top navigation has been shrunken roughly in half, and the 728 x 90-pixel banner ad near the top of the page has been eliminated.

Images and other multimedia components, including video, have moved from thumbnail compartments into larger, more prominent placements above and in-line with the article text. Longer articles are no longer paginated because the Times found that readers read further and stay longer when they don't have those obstacles, Ian Adelman, the Times' director of digital design, says

Did Samsung just put on a Broadway play instead of a traditional tech press conference? Why yes, we believe it did.

Following weeks of marketing hype in the form of teaser trailers and even a flash mob, Samsung launched on Thursday its Samsung Galaxy S 4 smartphone with much fanfare. And it was interesting, to say the least.

Held at Radio City Music Hall in New York City, Samsung put on quite a show for tech journalists, featuring tap dancers, Broadway performers and that little boy from the ads. Not to mention Broadway actor Will Chase served as the emcee. Yes, there was actually an emcee.

All we know about Doctor Who's real name is that there's only one reason why he would reveal it and there is only one time he could. Vague enough, Doctor?

So, what's the big secret? H. Caldwell Tanner of Loldwell ventures a guess in this comic

Finally, we understand why Doctor Who wouldn't want anyone to find out.
