The first full day of Olympic competition brought moments of tense excitement, in the pool and on the archery course, among other places. At the time of this post, China leads the overall medal count, with 6, followed by Italy and the United States, with 5. Four of China's medals are gold.

Alexander Vinokourov of Kazakhstan won the gold medal in the men's cycling road race Saturday, edging Rigoberto Uran of Colombia in a late sprint in London. The 150-mile race ended in front of Buckingham Palace.

The Olympic medal completes a vindication for Vinokourov, 38, who has previously been suspended for doping, back in 2007. He retired last year, after breaking his leg at the Tour de France. But he returned to the French classic this summer.

The London Olympics are in full swing, after an opening ceremony Friday that was chock-full of historic and cultural imagery drawn from Britain's past. Critics are gushing over Queen Elizabeth's role in the spectacle — along with James Bond. But there is room for debate — especially among viewers here in the U.S.

Good morning. Here's a rundown of what's been happening in and around London, on the morning after the Summer Olympics' opening ceremony:

- U.S. swimmer Dana Vollmer set new Olympic and U.S. records in her 100m butterfly qualifying heat this morning. Vollmer, of Granbury, Texas, had a time of 56.25 seconds. She says she can go faster.

- The first medals have now been awarded in the London 2012 Olympics, with China's Yi Siling winning gold in the 10-meter air rifle shooting competition. Poland took silver, and China took bronze, as well.

As we've reported, there were no public events on the Olympic sporting schedule today, the day of the opening ceremony. But we must note that two world records were set at the London 2012 Games this morning. That's when South Korean archer Im Dong-hyun scored a record 699 points.

U.S.gymnast McKayla Maroney will compete in the London Summer Games, despite the lingering effects of a broken toe. Maroney, a gold medal contender, is the reigning world champion in the vault. Early reports suggested that Maroney broke her toe in London. But it appears that she merely tweaked an earlier injury.

On Twitter, NBC producer Alexa Ainsworth clarified that Maroney's toe "was broken before Classic and she just aggravated that here."

Good morning, and welcome to "Day -1" of the 2012 Summer Olympics. That NASA-like designation is due to events already having begun in the soccer competition, before Friday's Opening Ceremony. Men's soccer begins play today.

Here are some stories that popped up overnight:

Mariel Zagunis, the two-time gold medalist in sabre, has been named the U.S. flagbearer for Friday's Opening Ceremony of the London 2012 Olympics. Zagunis, who was chosen by her peers for the honor, will be the first fencer to carry the flag since 1968, when Janice Lee Romary led the U.S. team in Mexico City.

On the first day of competition in the 2012 Summer Olympics, the U.S. women's soccer team bounced back from an early deficit to beat France, 4-2. The game was a rematch for the two teams that met in last year's World Cup semifinals.

France jumped out to a 2-0 lead before the match was 15 minutes old, scoring on a breakaway run by Gaetane Thiney; moments later, a short-range shot found the back of the net after several U.S. players failed to clear the ball following a corner kick.

Greek track star Voula Papachristou has been suspended from her country's Olympic team, after she made a comment about Africans who live in Greece. The comment was widely noticed on her Twitter feed, and resulted in her removal from the London 2012 roster.

On Twitter, Papachristou also reportedly expressed support for the right-wing Greek political party Golden Dawn, particularly its views on immigration.

The Hellenic Olympic Committee said that Papachristou "is suspended after her comments that go against the values and ideals of Olympism."

Just as every Olympic athlete trains their heart out, every Olympic expert seems to wear themselves out describing what an unmitigated sham is being perpetrated on the host city. Many of those criticisms are valid, of course — especially concerns about overbuilding facilities.

For instance, NPR's Louisa Lim recently reported on China's Post-Olympic Woe: How To Fill An Empty Nest.
