A 30-meter- turbine anchored to the seafloor off the Scottish coast is proving that tidal farms are a turn closer to being a viable renewable energy source.
A group of architects gathered in Oxford, England last month with an unusual brief -- to design the ultimate dream home for bats. The winged mammals are valued from an ecological viewpoint for preying on insects, dispersing seeds and pollination. But their numbers have declined dramatically in North America, where a fungal disease called white nose syndrome is estimated to have killed more than 5.5 million. In the United Kingdom, the fungus has yet to appear, but habitat destruction remains a major threat.
What you pay for medical procedures can vary drastically from city to city, hospital to hospital, even doctor to doctor - and there's not a whole lot you can do about it, according to a new report in Consumer Reports magazine.
Former attorney general: Economic policies will discourage Hispanics, not voter ID laws.
The Epsom Derby is the most famous horse race in Britain -- and, arguably, the world. Dating back to 1780, it has spawned many imitations -- 140 countries now have a "Derby," perhaps most notably in the U.S. state of Kentucky. Indeed, the word "derby" is now generally used to describe any race for three-year-olds.
In the movies, it's a familiar storyline: superheroes joining forces to tackle a world crisis. But CNN Heroes can do it, too. Marie Da Silva, Magnus MacFarlane-Barrow and Evans Wadongo are working together to help AIDS orphans in the African nation of Malawi.
With all the Facebook news lately -- the flat IPO, the regulatory interest, the Chan-Zuckerberg wedding -- it's highly possibly you've forgotten all about Twitter. If so, you'd be like most Americans. Only 8% of online Americans check their Twitter feeds on an average day, according to survey results released Thursday by the Pew Center for Internet & American Life. That's up from 2% in November 2010 and 5% in August, the group says, but it's nowhere near the numbers Pew tallies when it asks about online social networks in general.
John Edwards walked out of a courtroom Thursday a free man. How long will it take women attracted by the flame of celebrity -- even ill-gotten -- to date him? And believe they can convert him to monogamy?
Vendors court gay and lesbian couples as same-sex marriage gains acceptance.
The agony and ecstasy of the National Spelling Bee: In 2001, I walked into the editorial pit of the men's magazine where I was working as an art director and saw the almost all-dude staff glued to ESPN coverage. As I glimpsed the TV screen, a shock of panic and nausea wracked my body, and I bolted from the room. A friend followed to find me huddled in a ball at my desk. "I was ... there," I admitted. "In the Bee. I lost."
The jury in the John Edwards case rendered exactly the right verdict. Of course they couldn't make up their mind on most of the charges. No rational person could. The judge essentially instructed them to get into John Edwards' mind (as well as into the minds of several other actors in this political soap opera) and to determine precisely what his intention was in receiving money from friends.
Thursday afternoon, Barack Obama presided over the unveiling of George W. Bush's official portrait in the White House, a warm event that reminds us: It feels like years since President Dubya regaled the world with his famous spoonerisms. His retirement has been defined by an awkward silence. While John McCain's endorsement was trumpeted by Mitt Romney, Bush delivered his in just four words. "I'm for Mitt Romney," he shouted to a journalist as an elevator door closed between them. If, just for old time's sake, Bush had said, "I'm for Ritt Momney," it would have been perfect.
Yale grad's inspiring life over too soon, says CNN journalist Joshua Levs.
