Brazil: Dida, Cafu, Lucio, Juan, Roberto Carlos, Kaka, Emerson, Ze Roberto, Ronaldinho, Ronaldo, Adriano.
　　Subs: Cicinho, Cris, Fred, Gilberto, Julio Cesar, Juninho, Luisao, Mineiro, Ricardinho, Robinho, Rogerio, Silva.
　　
　　Australia: Schwarzer, Moore, Popovic, Neill, Chipperfield, Emerton, Grella, Sterjovski, Cahill, Culina, Viduka.
　　Subs: Aloisi, Beauchamp, Bresciano, Covic, Kalac, Kennedy, Kewell, Lazaridis, Milligan, Skoko, Thompson, Wilkshire.
　　
　　Referee: Markus Merk (Germany)
　　
　　"Brazil and Ronaldo seem to be mirroring each other. The team, like the player, are battling for form and rhythm but things just are not going their way. It will be interesting to see if Ronaldo allows his head to drop or continues to tries to build on the rare glimpses of quality he has shown."
　　Mandeep Sanghera, BBC Sport in Munich
　　
　　HALF-TIME: Australia end the half on the attack with Marco Bresciano firing a shot over. There have been few clear-cut opportunities but it is hard to imagine we are not going to see some after the break.
　　
　　45 mins: Mark Viduka runs at the Brazilian defence at one end, before Kaka races at the Australian rearguard. On each occasion they are carefully marshalled and the danger snuffed out.
　　
　　44 mins: It is another poor Australain corner. That’s the third they have had but they are yet to ask questions of the Brazilian defence with them.
　　
　　42 mins: Ronaldo reminds people what he is here for. Okay, he didn’t score, but he shows his strength by shrugging off the attentions of Vince Grella and, with very little back lift, fires in a shot that is wide of Mark Schwarzer’s left post.
　　
　　40 mins: Australia are forced to make a change with Tony Popovic hobbling off with a Marco Bresciano coming on. That means Scott Chipperfield goes into the back three.
　　
　　39 mins: Another booking and this time it is Jason Culina for a high foot in a tackle with Juan.
　　
　　38 mins: Adriano meets Kaka’s cross at an acute angle on the right, but goes with the wrong foot. Left-footed he could have got a strike on goal, but instead it was the right back across goal without a yellow shirt in sight.
　　
　　37 mins: Kaka plays in Ronaldo on the right of the area but the Real Madrid striker has an air shot. Not the easiest of opportunites but a chance he should have at least got a boot to.
　　
　　34 mins: Australia look for an opening but can find no way through the Brazil defence. Vince Grella shoots from distance but it is off target.
　　
　　32 mins: Ronaldo has the ball in the net and gets a yellow card for his troubles. Having been pulled back for offside he lashes the ball goalwards and Markus Merk reaches for his top pocket.
　　
　　31 mins: Mile Sterjovski breaks down the left but stops when he hears a phantom whistle. There was no offside flag.
　　
　　29 mins: Cafu is caught out by Tim Cahill and concedes a free-kick which earns him a yellow card. Dida punches the free-kick from the right clear.
　　
　　28 mins: Ronaldinho clips a chip into the box which Ronaldo runs on to but he shins his contact and Craig Moore blocks.
　　
　　27 mins: Mark Viduka is half-tackled and the ball breaks to Jason Culina. With Brett Emerton outside him he is greedy in taking the shot, particularly as it was not a particularly difficult one for Dida.
　　
　　25 mins: Bayern Munich’s Ze Roberto wins a soft free-kick in his home ground. Brazil break but Ronaldinho’s slip in the area means the move breaks down.
　　
　　23 mins: "Ronaldo is getting little sympathy from the Australian fans on the three occasions he has lost the ball. In his defence, he is showing signs of being a willing runner but is quickly being closed down when he has the ball."
　　Mandeep Sanghera, BBC Sport in Munich
　　
　　21 mins: Ronaldinho slips through the gears and is cruising into the box when Lucas Neill slides in with a well-timed tackle to stop the Brazilian in his tracks.
　　
　　18 mins: Tony Popovic climbs high to head clear a Ronaldinho free-kick from the left.
　　
　　16 mins: There may be more than 40 places between the teams in the Fifa world rankings, but it is not showing at the moment.
　　
　　13 mins: Brett Emerton celebrates his 50th cap with a yellow card for dissent. He is aggrieved at a free-kick going the other way after a non-descript challenge on Roberto Carlos.
　　
　　12 mins: Scott Chipperfield cuts in off the left flank and plays in Jason Culina, but his daisy-cutter shot is easily saved.
　　
　　10 mins: Vince Grella goes in for a tackle on Ronaldo and his boot comes up off the ball and scrapes down the Brazilian’s shin. It is a free-kick on the edge of the area, right of centre. Roberto Carlos blazes the ball wide.
　　
　　9 mins: Jason Culina swings in a corner from the left but it is over-hit and evades everyone.
　　
　　6 mins: Mark Viduka locks his sights on goal and lets fly from distance. It is a comfortable save for Dida – despite the late skip off the turf – down on one knee.
　　
　　3 mins: Ronaldo’s second and third touches are deft. A neat chest down and a light overhead volley into the path of Kaka who cracks a shot wide.
　　
　　2 mins: Scott Chipperfield fouls Kaka on the left of the pitch. Ronaldinho’s inswinging free-kick causes concern in the Australian ranks but they clear.
　　
　　1 min: Ronaldo watch – his first touch is poor.
　　
　　1700 BST: Brazil get the ball rolling in the early evening sun in Munich. It is lunchtime in Brasilia (1300 local time) and the early hours in Sydney (0200 local time). In the Australian Republic of Shepherd’s Bush (London, local time 1700) it is standing room only in the Walkabout, outside which people are snaking round the block to get in.

I was interviewed on television recently and, in answering the questions, I found myself expressing my contempt for the various superstitious beliefs that plague humanity.
　　We live in times when overpopulation,pollution,the greenhouse effect,the thinning of the ozone layer;the deterioration of the environment,the destruction of the forests and of wildlife,and the dangers of multiplying nuclear armaments all threaten us with the destruction of civilization and the radical reduction in the very viability of Earth.If our only answer to all this is a superstitions reliance on something outside ourselves as a solution to all those problems,we are making that destruction certain.
　　Countless millions of people all nevertheless feel much better consulting fortune-tellers,palm-readers,and astrologers.
　　
　　Countless millions of people place their faith not in God but in an infinite number or shapes and forms.
　　
　　The vast majority of human beings still take solace and comfort in their various superstitions and still follow any pied piper who fills their ears with notes of nonsense while filling his or her own pockets with money.
　　
　　And we are still in the minority and still struggling to convince people that,if,indeed,there were a god ,he would in the end reject anyone who failed to make use of that one truly godlike gift.
　　 But if that is so,and if we are engaged in a never-ending fight with no victory in sight,why continue?
　　
　　Any one individual we may win for the cause may do more for humanity than a hundred thousand who hug their superstitions to their breast.

Facial features can be clues as to whether a member of the opposite sex is after a one-night stand or something more permanent, scientists say.On men, a square jaw, large nose and small eyes are more likely to betray the look of lust than of love. On women, the give-away features tend to be wide eyes and large lips, a la Angelina Jolie. The Durham University-led research said women found men with softer features more likely to opt for commitment.
　　
　　　 　But while men can judge whether a woman is footloose-and-fancy-free, there was no common facial detail to explain it.
　　
　　 About 700 heterosexuals took part in the survey carried out by Durham, St. Andrews and Aberdeen universities.
　　
　　 In one study, 72 percent of the 153 participants correctly identified the sexual attitudes of a group of men and women in their 20s after being shown photographs or facial images.
　　
　　 Published in the journal "Evolution and Human Behavior", the research also showed that women who were open to short-term sexual relationships were usually seen as more attractive.
　　
　　 Women were usually interested in men who appeared to be more likely to want a long-term relationship. The research tended to confirm earlier findings which found that women see masculine men as more likely to be unfaithful and worse at parenting. The men and women also tended to opt for complete opposites.
　　
　　 Lynda Boothroyd, from Durham University’s Psychology Department, said: "This shows that these initial impressions may be part of how we assess potential mates when we first meet them.
　　
　　 "These will then give way over time to more in-depth knowledge of that person as you get to know them better, and may change with age."
　　
　　 Ben Jones, from the University of Aberdeen’s Face Research Lab, said: "Lots of previous studies have shown that people can judge a lot about a person from their face, including things like health and even some personality traits like introversion, but this really is the first study to show that people are also sensitive to subtle facial signals about the type of romantic relationships that others might enjoy."

EN ROUTE TO SHANGHAI—The world’s largest high-speed rail network. The world’s longest ocean bridge.We said it once before, we’ll say it again.
　　China likes its superlatives.
　　
　　And on Thursday it had two more infrastructure projects to crow about.
　　
　　First, the world’s longest sea bridge opened in Qingdao.
　　
　　At 23 miles long, the Qingdao Jiaozhou Bay Bridge has eight lanes and connects two districts within one of China’s prettiest port cities. The journey between the two regions is now shorter by nineteen miles and by half the original travel time of forty minutes. It took $2.3 billion and four years to build.
　　
　　But the second was much more impressive. And controversial.
　　
　　The Beijing-Shanghai high-speed rail link opened for business Thursday afternoon.
　　
　　Thousands of Chinese passengers turned up at Beijing’s South Railway Station, tickets in hand.
　　
　　“I’m excited,” said Tina Cheng, an IT marketing executive who paid 550 yuan ($85) for her second-class ticket on the express train, which will barrel through three municipalities and four provinces at 188 miles an hour to reach Shanghai in under five hours. “It’s a moment of pride for the Chinese people.”
　　
　　The new railway line was built in 39 months, almost a year in advance. Rail officials and engineers tested the line for at least a month before opening one day ahead of the Chinese Communist Party celebrating its 90th year on Friday.
　　
　　“This is not only for our employees but also for our country,” said Tian Lijun, the Deputy Director of the Bogie Assembly Workshop at the CNR Changchun Railway Vehicles Co., Ltd. His company is one of two that produce the rolling stock for the Beijing-Shanghai high-speed link. “I think this is a gift for our Communist Party.”

BEIJING, Aug. 25 — No country in history has emerged as a major industrial power without creating a legacy of environmental damage that can take decades and big dollops of public wealth to undo.
　　
　　But just as the speed and scale of China’s rise as an economic power have no clear parallel in history, so its pollution problem has shattered all precedents. Environmental degradation is now so severe, with such stark domestic and international repercussions, that pollution poses not only a major long-term burden on the Chinese public but also an acute political challenge to the ruling Communist Party. And it is not clear that China can rein in its own economic juggernaut.
　　
　　Public health is reeling. Pollution has made cancer China’s leading cause of death, the Ministry of Health says. Ambient air pollution alone is blamed for hundreds of thousands of deaths each year. Nearly 500 million people lack access to safe drinking water.
　　
　　Chinese cities often seem wrapped in a toxic gray shroud. Only 1 percent of the country’s 560 million city dwellers breathe air considered safe by the European Union. Beijing is frantically searching for a magic formula, a meteorological deus ex machina, to clear its skies for the 2008 Olympics.
　　
　　Environmental woes that might be considered catastrophic in some countries can seem commonplace in China: industrial cities where people rarely see the sun; children killed or sickened by lead poisoning or other types of local pollution; a coastline so swamped by algal red tides that large sections of the ocean no longer sustain marine life.
　　
　　China is choking on its own success. The economy is on a historic run, posting a succession of double-digit growth rates. But the growth derives, now more than at any time in the recent past, from a staggering expansion of heavy industry and urbanization that requires colossal inputs of energy, almost all from coal, the most readily available, and dirtiest, source.
　　
　　“It is a very awkward situation for the country because our greatest achievement is also our biggest burden,” says Wang Jinnan, one of China’s leading environmental researchers. “There is pressure for change, but many people refuse to accept that we need a new approach so soon.”
　　
　　China’s problem has become the world’s problem. Sulfur dioxide and nitrogen oxides spewed by China’s coal-fired power plants fall as acid rain on Seoul, South Korea, and Tokyo. Much of the particulate pollution over Los Angeles originates in China, according to the Journal of Geophysical Research.
　　
　　More pressing still, China has entered the most robust stage of its industrial revolution, even as much of the outside world has become preoccupied with global warming.
　　
　　Experts once thought China might overtake the United States as the world’s leading producer of greenhouse gases by 2010, possibly later. Now, the International Energy Agency has said China could become the emissions leader by the end of this year, and the Netherlands Environment Assessment Agency said China had already passed that level.
　　
　　For the Communist Party, the political calculus is daunting. Reining in economic growth to alleviate pollution may seem logical, but the country’s authoritarian system is addicted to fast growth. Delivering prosperity placates the public, provides spoils for well-connected officials and forestalls demands for political change. A major slowdown could incite social unrest, alienate business interests and threaten the party’s rule.
　　
　　But pollution poses its own threat. Officials blame fetid air and water for thousands of episodes of social unrest. Health care costs have climbed sharply. Severe water shortages could turn more farmland into desert. And the unconstrained expansion of energy-intensive industries creates greater dependence on imported oil and dirty coal, meaning that environmental problems get harder and more expensive to address the longer they are unresolved.
　　
　　China’s leaders recognize that they must change course. They are vowing to overhaul the growth-first philosophy of the Deng Xiaoping era and embrace a new model that allows for steady growth while protecting the environment. In his equivalent of a State of the Union address this year, Prime Minister Wen Jiabao made 48 references to “environment,” “pollution” or “environmental protection.”
　　
　　The government has numerical targets for reducing emissions and conserving energy. Export subsidies for polluting industries have been phased out. Different campaigns have been started to close illegal coal mines and shutter some heavily polluting factories. Major initiatives are under way to develop clean energy sources like solar and wind power. And environmental regulation in Beijing, Shanghai and other leading cities has been tightened ahead of the 2008 Olympics.

Origins: The festival began as early as the Warring States Period (475 – 221 BC). According to the yin/yang dichotomy that forms a basis to the Chinese world view, yin represents the elements of darkness and yang represents life and brightness. The number nine is regarded as yang. The ninth day of the ninth month is a double yang day, hence the name "Chong Yang Festival". (Chong means "repeat" in Chinese.) The ninth month also heralds the approach of winter. It is a time when the living need warm clothing, and filial Chinese sons and daughters extended this to make the festival a time for providing winter clothes for their ancestors. The Double Ninth Festival, therefore, also became an occasion to visit the graves of dead family members. Clothes made of paper would then be burnt as offerings.
　　
　　Climbing mountains: On the Double Ninth Festival, people customarily climb mountains, appreciate chrysanthemum flowers, drink chrysanthemum wine, eat double-ninth cakes, and wear the zhuyu plant, Cornus officinalis. (Both chrysanthemum and zhuyu are considered to have cleansing qualities and are used on other occasions to air out houses and cure illnesses.). The Double Ninth Festival is also the "Old Men Festival". Old people are especially meant to improve their health by taking part in the activities on the day of the festival.
　　
　　Family get-togethers: The Double Ninth Festival is also a time for family get-togethers. It is an occasion to remember one’s ancestors, the sacrifices they made and the hardships they underwent. Often, family outings are organized during which people search to renew their appreciation of nature and to reaffirm their love and concern for family members and close friends.

Harnessing the untapped power of breast motion.
　　By Adrienne So
　　Posted Monday, June 23, 2008, at 4:10 PM ET
　　
　　As a woman who loves sports, I’ve always found the concept of breasts bothersome. If all goes according to plan, they will fulfill their intended function for about three of the 70 years that I have them. The rest of the time, they alternate between getting in my way and embarrassing me. They are a favorite target of Frisbees and soccer balls. Finding sports bras is a chore. Shirts don’t fit.
　　
　　And these are just the physical discomforts. I am still tortured by the memory of three cousins standing in a circle around me, at the impressionable age of 10, mocking my early development and telling me that I was going to be the Asian Dolly Parton. Fortunately, that never happened, but the possibility haunted my late childhood.
　　
　　Then one day recently I had an idea. As I rode public transportation to the office, my messenger bag slung uncomfortably across my chest, I thought, "Why not put the girls to work?" Human-powered devices are showing up everywhere, from Rotterdam’s sustainable dance floor to human-powered gyms in Hong Kong. The time seemed perfect—perhaps even overdue!—for a bra that could harness the untapped power of breast motion.
　　
　　The idea of an energy-generating bra isn’t as crazy as it might sound. A company called Triumph International Japan recently unveiled a solar-powered bra that supposedly will generate enough energy to power an iPod. But I live in foggy San Francisco and prefer not to walk around in my underwear in public. Could someone design an iPod-powering bra for me?
　　
　　I decided to run the question past some scientists. It turns out that the physics of breast motion have been studied closely for the last two decades by a gamut of researchers, most of them women. LaJean Lawson, a former professor of exercise science at Oregon State University, has studied breast motion since 1985 and now works as a consultant for companies like Nike to develop better sports bra designs. Lawson was enthusiastic about my idea but warned it would be tricky to pull off. You would need the right breast size and the right material, she explained, and the bra itself would have to be cleverly designed. "It’s just a matter of finding the sweet spot, between reducing motion to the point where it’s comfortable but still allowing enough motion to power your iPod," she said.
　　
　　Lawson explained that breasts move on three different axes: from side to side, front to back, and up and down. The most motion is generated on the vertical axis. Naturally, the bigger the breast, the more momentum it generates. "Let’s face it—if you’re a double-A marathoner, you’re probably not going to get that iPod up and running," Lawson said. Measurements compiled by Lawson and her colleagues show that a D-cup in a low-support bra can travel as much as 35 inches up and down (35 inches!) during exercise, while a B-cup in a high-support bra barely moves an inch.
　　
　　Fabric and design are also important factors in distance traveled. Elastic fabric allows the breast to move more. Choosing between an encapsulation design, in which the cups are separated, or a compression design, where they are hugged close to the body, can also affect breast motion. An encapsulation design further reduces motion because two smaller masses are easier to control than one large one. "Also, if you have a really high neckline, the breasts won’t fly up," Lawson said. So I was in the market for an elastic, compression-style bra with a low neckline. Sexy!
　　
　　Of course, even a bra that perfectly maximized motion (without sacrificing support and comfort) would be useful to me only if there were a way to turn that motion into energy. For a primer on how to do that, I turned to Professor Zhong Lin Wang of Georgia Tech, who is currently working to develop fabric made from nanowires that will capture energy from motion. Wang’s wires are about 1/1,000th the width of a human hair. When woven together in a fabric, these nanowires rub up against one another and convert the mechanical energy from the friction into an electric charge. According to Wang, the fabric is cheap to produce and surprisingly efficient; his team hopes to use it to create energy-generating T-shirts and other articles of clothing. A square meter of fiber produces about 80 milliwatts of power, which is enough to run a small device like a cell phone. Wang expects to have a shirt available for purchase within five years.
　　
　　Many bra patterns call for about a meter of fabric, which would probably mean that a regular bra would have enough energy to power an iPod. But the fabric could also be layered, doubling or even tripling the amount of energy produced. I asked Wang whether his fabric could be used to make a bra. "Bras would be ideal," he said. "There is a lot of friction and movement in that general area. And the fabric would be thick."
　　
　　"So you can generate enough energy to power an iPod?" I asked.
　　
　　"Definitely," Wang said.
　　
　　I asked Wang if this bra would be machine-washable.
　　
　　"You don’t need to wash a bra!" he said.
　　
　　I disagreed. Wang said his team has been working on the washing problem for a while. Nanowire technology can generate electricity only if the space between the wires is maintained, and that space might be affected if the fabric were agitated by washing. One solution would be to layer the fabric so that the parts that directly touch the skin could be washed, leaving the nanowires in between untouched.
　　
　　There was one more approach I wanted to investigate, one that might supplement Wang’s technology. Was there a way to capture the energy of the bra strap, which bears the pressure of holding up the breast mass? To answer this question, I called Larry Rome, a biology professor at the University of Pennsylvania and the creator of Lightning Packs. The Lightning Pack, intended for long-haul hikers and for the military, generates kinetic energy from the vertical displacement of a heavy backpack. Would it be possible to use the kinetic energy generated from a breast’s vertical displacement?
　　
　　"The backpacks we’ve built are intended to carry between 40 to 80 pounds," Rome said.
　　
　　I cited the D-cup numbers given to me by Lawson. "Well, that’s not normal, is it?" Rome asked.
　　
　　I said that it probably wasn’t. Yet after a moment’s thought, Rome came up with an idea. The Lightning Pack uses a rotary generator, which converts motion into energy by winding a rotor as the backpack moves up and down. Rotary generators produce up to 7 watts of energy, enough to power a compact fluorescent light bulb. Rome said it might be possible to insert a linear generator into the bra. A linear generator is a lot smaller and creates energy by moving a piston up and down. Rome conceded that with the right body type, this just might work, though he warned it "probably wouldn’t be very comfortable."
　　
　　Still, if someone were to engineer a kinetically powered bra, even one that isn’t quite as comfortable as the old-fashioned kind, I’d be intrigued—and I might just start looking at my breasts in a different light. Maybe it’s not very sexy to see breasts as a pair of batteries, but oil prices are so high, people are jogging to work. It may be time for breasts to start pulling their own weight.
