Sunny, warm weather embraced London on Thursday amid last-minute preparations for the Summer Olympic Games, now less than 24 hours away. Crowds cheered on the Olympic torch as it wound its way past some of the capital's most famous landmarks.
As tens of thousands of athletes, team officials and visitors gather in London ahead of the Olympic opening ceremony on Friday, security is paramount for the Games organizers and British authorities. And perhaps the biggest headache of all is the challenge of safeguarding the more than 100 heads of state and foreign dignitaries who will attend the opening ceremony at the Olympic Park -- Queen Elizabeth II, first lady Michelle Obama and U.S. presidential hopeful Mitt Romney among them. But should visitors and competitors be worried?
The day of the Olympic opening ceremony, demonstrators are set to gather outside the stadium in protest against major sponsor Dow Chemicals. Members of the Bhopal Medical Appeal plan to hold a 'die-in' Friday morning in protest against the company it claims has responsibility for the fatal 1984 gas leak in India.
Members of Egypt's Olympic team were given fake Nike gear to wear during training in London, athletes and a distributor said.
Watching the Olympics, which kick off in earnest Friday with the opening ceremony in London, is more fun when you know the stories behind the Games. No doubt, sports broadcasters will hammer on plenty of rags-to-riches, against-the-odds backstories about the Olympic athletes. (You can also find plenty of them on CNN's London 2012 page). And that's all good. But knowing the technological underpinnings of the Games is perhaps just as intriguing. Here's a quick look at five of the most interesting tech stories to watch at the London Olympics:
Tournament favorites Spain have suffered one of the biggest upsets in Olympic football history, losing 1-0 to Japan at Glasgow's Hampden Park on Thursday.
Members of North Korea's women's Olympic soccer team walked off the field Wednesday when the flag of South Korea was mistakenly flashed on the big screen before their match against Colombia. Perhaps organizers can take comfort in knowing that it's not the first time officials have bungled a flag or an anthem.
An Indian court has ruled that the organizer of the scandal-plagued 2010 Commonwealth Games in New Delhi is forbidden from attending the opening ceremony of the London Olympics.
An Olympic gold medal is no guarantee of subsequent success as a professional boxer, but it meant the world for Wladimir Klitschko.
John Orozco won his first medal in gymnastics when he was 9. But he didn't hold onto that medal for long, giving it to another boy in the competition who was in tears after being teased for a bad performance.
Attorneys for one of the victims Jerry Sandusky was convicted of abusing have released two voice mails that they say the former coach left on their client's phone just prior to his 2011 arrest -- potential fodder for a civil lawsuit they now plan to file against Penn State and others.
Three adults and two juveniles were arrested Wednesday for allegedly terrorizing a Jewish camp in Pennsylvania. Authorities say Tyler Cole Spencer, 18, Mark Trail, 21, Cassandra Robertson, 18, and two juveniles intimidated Jewish campers and staff at Camp Bonim on three separate occasions on July 14 and 15.
