U.S. Diver David Boudia Earns Bronze in 10m Platform

No one has a better view of Olympic Park than a diver. Towering 10 meters above the water, the platform offers an unparalleled view of Lagoa de Barra, the lake adjacent to the Park and the Olympic Village beyond. But the 12 men in the 10m platform final likely weren’t even paying attention to their unique vantage point. Instead of looking out beyond the Maria Lenk Aquatics Center, they were looking down, at the now crystal-blue water below that was pockmarked with the steady drizzle of a dampening rain. Just days before, the diving well and the practice pool adjacent to it in the open-air center had turned a disturbing emerald green, the result, Olympic officials said, of an accidental overdose of hydrogen peroxide. After being drained and re-filled, the water regained its normal aqua hue in time for the final diving event of the Games. Under a constant drizzle that sent most fans under cover of umbrellas or plastic ponchos at the start of the competition, the divers seemed unfazed by competing with the weather. After six rounds of dives that saw Chinese favorite Qiu Bo falter and Mexico’s German Sanchez surge, Aisen Chen of China secured gold, while Sanchez dove to silver and the U.S.’s David Boudia won bronze. It’s the second gold for Chen in Rio; together with partner Yue Lin, captured gold in the synchronized 10m platform during the first week of competition. In diving, it’s all about the right dive at the right time, with one bad leap off the platform could mean the difference between a medal and going home empty. Boudia earned two perfect scores, 10.0, on his second round inward three and a half somersaults in the tuck position while But Qiu, the silver medalist from 2012, overextended after opening up from his back triple somersault pike to earn 4.5s across the board, which landed him in last place after the round. Qiu bounced back with a sweep of three 10.0 scores for his third dive, a reverse three and a half somersault in the tuck position, which pulled him up to sixth place after the round. German Sanchez from Mexico began making his bid for the podium with the second highest score of the round. In the fifth round, Boudia executed a crisp two and a half twists into two and a half somersaults in a pike position and practically melted into the water. But Chen’s higher difficulty forward four and a half somersaults in a tuck pulled him into first ahead of Boudia. Qui took another risk with an even higher difficulty dive and overextended the entry for another set of 4.0 and 4.5 scores, dropping him to seventh. For his final dive, Boudia threw off the same skill as Chen had in the previous round; while tight in the air, it wasn’t as clean on the entry and earned him 6.0s and a 6.5. Sanchez answered back with scores of 8.0 which pulled him ahead into second place, in front of long-time friend Boudia. Chen finished off with a perfect back two and a half twists and two and a half somersaults and disappeared into the water on his entry to clinch the gold with three perfect 10.0s. “It’s easy to be discontent with the result,” said Boudia. “Missing my last dive which has been a strength of mine, at the Olympics; it was almost mine to lose. But to know that I could miss this dive and become the bronze medalist at the Olympic Games is pretty special.” Finishing on the podium for Boudia, who recently detailed his struggles after finishing fifth at the 2008 Beijing Games in the 10m platform in his memoir, Greater Than Gold, wasn’t necessarily a disappointment. He admitted to having suicidal thoughts after leaving Beijing without a medal, but credits religion with helping him to earn gold in 2012 and stay on the podium in Rio. Training for Rio as the defending champion was also a strain, he said. “This [medal] is a lot more special because the past four years has been extremely difficult,” he said. “The road — getting married, having my first child with my wife, and trying to defend the gold — the pressure that comes with that is not easy.” No one is more familiar with that than Tom Daley of Great Britain, the 2012 Olympic silver medalist, who notable for his absence. After finishing first in the preliminary round the previous day, Daley finished last among the 18 in the semi-finals after faltering on his second (a forward three and a half somersaults with a twist) and third (an armstand to back three somersaults) dives, among the most difficult ones he performs. Only the top 12 move on to the finals. “I really don’t have a reason,” he said of his missed dives in the semi-final round. “I’ve been diving like I’ve been diving [in the preliminaries] for the last three weeks leading up to this and that’s why it’s so hard to take in. It’s just really tough to think how well it went yesterday and if I’d just done that 24 hours later, managed to do it in the final, it could have been an Olympic gold medal around my neck, but instead it’s heartbreak.” Daley, along with Boudia, have been challenging the Chinese dominance in the event. At last year’s world championships, Boudia earned silver and Daley bronze behind Qiu, while Boudia bested Qiu at the last Olympics in London and Daley came in third. “I’m kind of in shock because I know that I could win that gold medal and I think right now I’m the only one that could challenge the Chinese for that gold medal,” Daley said after missing the chance to dive in the finals. Daley has now missed out on Olympic gold three times; in 2008, he finished eighth. Qiu, 23, from Beijing, has won the last three world championships in the event, while Chen, after winning gold in the synchronized event, was in the zone. Executing their dives with the crisp precision and tight tucks that have become the hallmark of the Chinese team, Chen also capped off the spectacular show of acrobatics with near splash-less entries, another points-getting technique he and other Chinese divers have mastered. “We don’t have a strong religion in China so people who win gold medals are our gods; they are our heroes,” says Peng Hao, a photographer from Chengdu, China who traveled to Rio to see the Games. “We will remember them forever.” What’s behind their ability to conquer the art of flinging yourself into space before plunging into a pool? Zhuqiao Li, also from Chengdu, has a theory. “I think diving is suitable for Chinese,” she says. “The Asian body is not suitable for running because we are smaller than Europeans so maybe in diving we have an advantage.” Divers in China also have the opportunity to become superstars in their country, Advertisers find medalists attractive, and they often find their images gracing the opening screen of smartphone apps. Chen will likely find his image appearing in quite a few of those in coming months. […]

Something Is Wrong With the U.S. Men’s Basketball Team

Yes, this was really happening. Serbia’s Bogdan Bogdanovic found himself wide open on the left wing in the last second of Friday night’s Olympic men’s basketball preliminary game against the United States. The U.S. held a 94-91 lead. If Bogdanovic sank this shot, the game was going to overtime. Since the U.S. finished with an embarrassing bronze medal at the 2004 Athens Games, no team has come closer to beating them at the Olympics. Bogdanovic missed, but the message was clear: Team USA is not playing like the gold medal-favorite, NBA All-Star-packed team that they are. Two days before, the U.S. trailed Australia for much of the game before pulling away late. Sure, this year’s team is missing many of America’s best players, most notably LeBron James and Stephen Curry. But it’s still packed with stars like Carmelo Anthony, Kevin Durant and Kyrie Irving. But has only one active NBA player on their team (Nikola Jokic, an up and comer with the Denver Nuggets who finished with 25 points and six rebounds against the U.S.). What is going on? To hear some members of Team USA tell it after the close call against Serbia, the problem is defense. “Defensively,” says forward Paul George, of the Indiana Pacers, “is where we have to man up.” Serbia coach Sasha Djordjevic says he borrows his offensive philosophy from the San Antonio Spurs, who’ve won five NBA titles since 1999. The ball is always moving, causing the defense to give chase. This strategy is particularly effective against a more athletic opponents. Bigger, faster players can easily stop inferior ones if they’re just going to the basket against them one-on-one: their physicality gives them an overwhelming advantage. But when these superior players are caught moving around on defense, the offense can more easily counter-strike. After the game, both U.S. coach Mike Krzyzewski and George gushed about Serbia’s ball movement. But should it have really caught the U.S. so off guard? They all play against the Spurs. “In our game, there’s movement obviously,” says George. “With these guys, it’s constant movement. We talked about it in the back. You never sit still. In our game, there are moments when you sit still. You can have a rest period. You might get action that guys just run on one side. [Against Serbia], you’re constant moving from side to side. They don’t get tired.” One of George’s teammates, however, faults the offense. Draymond Green of the Golden State Warriors, who was held scoreless in 13 minutes, blamed Team USA’s listless offense for its failure to put Serbia away. “I don’t think it’s ball movement,” says Green. “I think our offense is hurting our defense as well. When we were moving the basketball early on, everything was flowing, the defense was great. When we stop moving the basketball, everything is stagnant. It transferred over to the defensive end.” Green’s hitting on something here. The U.S. needs to spend less time praising the way Serbia plays, and more time playing like Serbia. After playing some more games together, Team USA will improve its teamwork. But are the Americans running out of wiggle room? The U.S. plays one more preliminary game Sunday against France, led by Tony Parker and Boris Diaw– uh oh, more Spurs. The quarterfinals begin Aug. 17. This team was cobbled together quickly after many other stars dropped out. Only Anthony and Durant played in London. The team seems to realize their margin for error is getting smaller. “As good as we are, if we keep playing like this,” says George, “these games are going to keep getting tougher. […]

Serena Williams Wins Rio Opener in First Match Since Wimbledon

RIO DE JANEIRO—Perhaps it was the 25 mph winds. Or the slower-than-expected hard courts. Or maybe simply that Serena Williams hadn’t played a match in a month. Whatever the cause, Williams opened defense of her Olympic singles gold medal with a patchy-at-times 6-4, 6-2 victory over Australia’s Daria Gavrilova on Sunday, gesturing or yelling at herself as she often does when not all goes her way. “I’m always frustrated on the court if it’s not perfect,” the American said. Williams had not competed since collecting her Open-era record-tying 22nd Grand Slam title at Wimbledon. She’s now won 19 of her past 20 matches. Seeded No. 1 at the Rio de Janeiro Games, Williams was hardly at her best in the 91-minute contest against Gavrilova, who is ranked 46th and only once has been past the second round at a major tournament. While that match was played in the main stadium, action was delayed because of strong winds for about 2 hours on the eight smaller Olympic courts. “I was a little nervous about that,” Williams said of her reaction to hearing of the gusty conditions, which she called “very intense.” Williams compiled 37 unforced errors to 27 winners, and got broken at love while serving for the first set at 5-3, a game that included a tremendously entertaining point. The lengthy exchange featured terrific defense by both women and ended with Williams putting a forehand into the net. Afterward, she leaned over near the net, while Gavrilova dropped to her knees on the court, letting go of her racket. But Williams broke right back in the next game to take the set. “The first set, especially, was extremely tricky,” Williams said, referring to the wind, “but I’m glad it kind of slowed down in the second a little bit, so I was able to produce better tennis.” Players have noticed that the green courts in Rio play slower and offer higher bounces than hard courts used on the North American circuit leading to the U.S. Open later this month. “Fortunately enough, I am a pretty good clay-court player, so I’m OK with the slow courts,” said Williams, a three-time French Open champion. “You have to hit about three or four more shots or just play a little bit better. It’s OK. I’m getting used to the conditions as a whole.” She was scheduled to play doubles with her older sister Venus later Sunday. U.S. Tennis Association spokesman Tom LaDue said that Venus would participate in that match despite being sick. On Saturday night, Venus’ availability for doubles was put in doubt by U.S. women’s tennis coach Mary Joe Fernandez, who said the four-time gold medalist and seven-time Grand Slam champion had cramping, dehydration and an upset stomach following a first-round loss in singles.

See the Effects of Climate Change in 3 Birds

Looking for signs of climate change? You can check the temperatures of the oceans or the density of polar ice caps. Or you can see which birds are gathering outside your window. A Birds & Climate Change report released this week by the Audubon Society predicts that global warming will severely threaten nearly half of U.S. birds by the year 2100. And birds are already on the move, according to the society’s research. By mapping the information for the Audubon’s climate predictions, we see can that birds have migrated further north by an average of 40 miles in the past 48 years as temperatures increase. The map above highlights three species whose center of abundance has moved by over 200 miles. The winter migration data is the fruit of the longest citizen science project in existence, called the Christmas Bird Count. Thousands of volunteers across North America head out every winter to track bird locations in over 2,300 designated areas. Audubon scientists aggregate data along conservation regions and state lines and then they account for the varying effort of bird watchers (watch out slackers) to produce an “abundance index” for each species. The maps reflect this index for three birds that highlight how warmer winters are influencing species differently. Sixty one percent of the 305 Christmas Bird Count species are moving north — some by more than 200 miles, like the Pine Siskin and American Black Duck. Fewer species are going south, as their winter ranges are shrinking on the whole, with the remaining suitable climates now left further south. This pattern is observed in the Peregrine Falcon, though its increased abundance is also due to pesticide bans. The “all birds” map shows the abundance index of all observed species relative to other areas. Light green areas show where fewer than the average number birds was observed, while darker areas exceed the average. Over time, areas further north illustrate increasing abundance relative to other areas. Methodology Data was provided by the Aududon Society, with calculations by Candan Soykan, an ecologist for Audubon. The “abundance index” for the three species shown on the map is based on the number of birds observed, by species, for each survey in the Christmas Bird Count, adjusted for variation in bird watching effort, among other factors. The relative abundance for the map of bird density standardizes each species’ abundance index to a common scale before combining across species to provide an overall estimate. Standardization prevents abundant or more detectable species from dominating patterns in the map. To accommodate some species dramatically changing in abundance over the 48-year interval, median values are used. These median values for each year are averaged by decade (except in the case of 1966 to 1973) to be used on the time slider and map. […]

Strong Solar Flare Headed Toward Earth

A strong solar flare is barreling toward Earth at 2.5 million miles per hour, but scientists say its worst effects will likely bypass the planet when it expectedly arrives by the weekend. Solar flares from the sun occur with frequency and, when unleashed toward Earth, can cause so-called solar storms. This particular one is categorized as a low-level X-class flare, the most severe of the three classes. A storm of this size hasn’t headed toward Earth in several years, Tom Berger, the director of the Space Weather Prediction Center in Boulder, Colo., told the Associated Press. But, he added, “we’re not scared of this one.” Earth’s atmosphere largely protects people on the ground from the radiation effects of a solar flare, but such blasts do have the potential to knock out power systems and disrupt satellite communications. Berger told the AP that the one heading toward Earth could slightly disturb some satellite and radio communications. Storms categorized as “Extreme” have the potential to cause massive damage to electrical and communication systems and even pose a health hazard to passengers and crew in high-flying planes. Here’s video footage from NASA of the solar flare in the middle of the sun on Wednesday: […]
