Sometimes to move forward you have to revisit your past.

Which explains Nokia's latest nod to the future, a reinvention of the classic Nokia 3310, a phone originally released in the year 2000, once labeled "the phone that could not be killed."

I write a lot about the ways the powers that be on Wall Street abuse their power; commit financial fraud without going to jail; get billions of dollars in subsidies and tax loopholes; and generally hurt the Main Street economy. One of the most significant things they do to mess things up for the rest of us is to use their enormous size and market power to manipulate markets. They do it all the time and in all different kinds of economic sectors. What makes this market manipulation even worse is when they do it in conjunction with government-subsidized markets, because they use our tax dollars to create big profits for themselves.

Three weeks ago, an editor sent me a link to the browser version of the hot new game "2048," saying I should cover it for The Huffington Post. It was popular because it was simple: You swipe numbered tiles back and forth, combining like numbers -- two 2 tiles make a 4, two 4 tiles make an 8, and so on -- until you reach the final goal of a 2048 tile.

The game was getting media attention as it rose to the top of the App Store's Top Free Apps list, and other sources hailed its 19-year-old creator, Gabriel Cirulli, as a wunderkind for creating a simple game capable of such viral success.

Product review sites are a staple of our online landscape. You can review hotels, electronics, and even mattresses, and a persuasive review can drive (or inhibit) sales of an item. Now, HugDug, a new product review site, is looking to harness the power of popular product recommendations, with a twist: Half of HugDug's profits go to charity.

"God help me, what have I done?" I thought as I stared down the length of my CrossFit gym. It was the evening of 14.1, the first of the five-part CrossFit Open 2014 competition. An intimidating, symmetrical line of barbells and crash pads faced me. The usually-inviting gym looked like the inside of a torture chamber: metal, ropes, and the smell of sweat and pain. Tonight was the very first night of the CrossFit Open and, heavens have mercy, I was signed up.

Just three weeks ago the Associated Press reported the Obama administration needed "something close to a miracle" in order to "meet its goal" of enrolling 6 million people into private health care plans via the Affordable Care Act before the looming April 1 deadline arrived.

Scientists have now used brain scanners to hack into our thoughts like never before.

After scanning the brains of men and women who were looking at photos of different faces, researchers at Yale University have found a way to reconstruct the image of those faces based solely on patterns of neural activity in the brain scans. Mind. Blown.

What does the newly discovered dwarf planet "Biden" have in common with Vice President Joe Biden? As our fun new infographic (below) shows, more than you might imagine.

Detected at the outer fringe of our solar system, the dwarf planet was officially designated 2012 VP113. But because of the VP in that alphanumeric designation, astronomers nicknamed it "Biden" after our flesh-and-blood VP.

Few individuals or institutions have the power to truly move markets like Warren Buffett and the Chinese government. When the two forces converged in 2008 to back Chinese electric car company BYD, the little-known brand rose to international fame. Buffett's Berkshire Hathaway put $230 million into buying a 10 percent stake in the company, and the Chinese government soon followed up with audacious targets for skyrocketing electric car production.

American students are barely above the average of 44 countries and economies in problem-solving skills, far behind teens in Asia, according to the first international test of that attribute in 15-year-olds.

U.S. teens on average earned a score of 508 on the Programme for International Student Assessment -- Creative Problem Solving test, between top-ranked Singapore's 562 and bottom-ranked Colombia's 399. The PISA results, released Tuesday, put U.S. students in the middle of the pack, hardly supporting the American workforce reputation for creativity.

According to press accounts, former Senator Jim DeMint is likely earning in the neighborhood of $1 million a year for heading up the Heritage Foundation, a right-wing Washington think tank. The fact that right-wing think tanks pay their top people lots of money is not exactly news. After all, they have lots of wealthy donors who are happy to cough up this sort of money. But the part of the story that might get people upset is the fact that the rest of us are subsidizing Mr. DeMint's hefty paycheck.

Everyone's talking about Obamacare today, since it is the deadline for signing up for health insurance in the first "open enrollment" period for the marketplace exchanges. The final numbers aren't in yet (and won't be for at least another few weeks), but from the numbers already released, the Obamacare website seems to have made an impressive turnaround from its ignoble beginnings.

OKCupid may be in the business of love, but the online dating site has anything but tender feelings for Mozilla and its newly-appointed CEO.

In a letter published Monday on OKCupid.com but viewable only to those who try to enter the site using a Mozilla Firefox Internet browser, the company called out CEO Brendan Eich's past support of Proposition 8, a 2008 ballot initiative that aimed to ban same-sex marriage in California.
