Russia-Elections Vladimir Putin remains a sure bet for the presidential election, despite weeks of protests unprecedented in the country's post-Soviet history. The leading opposition candidate in Sunday's vote is Russia's third-richest man, billionaire New Jersey Nets owner Mikhail Prokhorov. President Obama speaks to Sunday's session of AIPAC, the policy conference of the largest American Jewish lobbying organization. US-Fishing-Life-Threatened By daybreak, much of this town has already been at work for hours. Clad in yellow and orange rubber suits, these seafarers drag giant nets across the ocean floor during 12-hour work days, hauling back the fish they will later bring to market. For some 400 years, fishing has sustained communities such as Gloucester along America's northeastern shores, where thousands of seafood processors, wholesalers, distributors and retailers make a living off the waterfront. US-Freedom-Lincoln (with art) Sheila White was beginning to feel numb. She had been beaten numerous times by a man who forced her to work as a prostitute on the streets of New York City. "I done got beaten up in front of the Port Authority in Times Square," she said, a reference to a bus terminal on the city's West Side. When stuff like that happens out in the open, you really feel like you're not even a person. White was eventually able to escape her pimp and now works with victims of sex trafficking throughout New York state. But her story is proof that slavery is alive and well in America, 150 years after it was supposedly abolished.

What-Does-Iran-Want Throughout the course of the past year Iran has been, if anything, consistent in its delivery of provocative acts and bellicose rhetoric. An alleged plot to assassinate the Saudi ambassador to the United States is uncovered. Threats to close the strategic Strait of Hormuz are followed by refusals to allow U.N. nuclear inspectors access to certain sites in the country. Then there is the issue of alleged attempts to assassinate Israeli diplomats at the hands of Iranian operatives in India, Georgia, Thailand and Azerbaijan. And let's also not forgot the threats of pre-emptive military action against any country perceived as an imminent threat to the Iranian regime. What is one to make of what of it all? POL-Brokered-Convention Two months into the Republican presidential nominating process, many thought that one candidate might have it sewn up by now. MONEY-Foursquare-Ceo Foursquare CEO Dennis Crowley knows people think his location-based service is about a bunch of dorky teens and twenty-somethings running around and collecting virtual badges. But he also knows something that we don't: The load of information that his company is collecting from its league of nerds is a potential goldmine of data. TECH-Everyone-Gives-Web What if one small gift to your favorite charity could become dozens, hundreds or thousands? TECH-Waterproof-Mobiles (with art) The ability to work inside a fish tank is not high on most people's wish lists when it comes to buying a new smartphone. MED-Patients-Gouge-Own-Eyes Remember the myth of Oedipus, where the king of Ancient Thebes stabbed his own eyes after he realized he'd killed his own father and married his mother? As gory as it sounds, intentionally blinding oneself isn't entirely mythical. Although rare, there have been cases of people seriously injuring their own eyes, and sometimes completely removing them. There's even a technical term, self-enucleation, for the behavior of taking out your eyeballs.
