Liu Xiang sets the World 110m Hurdles record in Lausanne.
Lausanne, Switzerland — China’s Olympic champ/on Liu Xiang【21】the men’s 110m Hurdles World record with【22】12.88 seconds (wind +1.1 m/s) at tonight’s Athletissima, a Super Grand Prix meeting, which is part of the IAAF World Athletics Tour.
"I【23】thought I could break the World record. I'm feeling very fired, very happy and very excited," said Liu Xiang. "Switzerland is my【24】place. I love Switzerland and Lausanne and the fans here," the 22-year-old young man added. "I had【25】broken the World junior record in 2002 in Lausanne (13.12)." Liu Xiang celebrates【26】sitting on his World record clock in Lausanne.
"Tonight I started well running. But it was【27】the fifth hurdle when I speeded up," confirmed the 2005 World Championship silver medallist who will【28】his 23rd birthday on Thursday (13 July).
Liu Xiang was the joint holder of the【29】best of 12.91, which he【30】when winning the Olympic title on 27 August 2004 in Athens, Greece. The【31】12.91 record had been set in Stuttgart, Germany,【32】Britain’s Colin Jackson who established that mark when winning the World Championship【33】medal on 20 August 1993.
In second place tonight in Lausanne was Dominique Arnold of USA who led for most of the【34】, and finished in 12.90 seconds, which of course is also【35】the old record.

1. “The Nobel Prize in Physiology or Medicine 2004”Press Release(15分)
4 October 2004
The Nobel Assemblyat Karolinska Institutet has today decided to award The Nobel Prize in Physiology or Medicine for 2004 jointly toRichard Axel and Linda B. Buckfor their discoveries of "odorant receptors and the organization of the olfactory system"
Summary
The sense of smell long remained the most enigmatic of our senses. The basic principles for recognizing and remembering about 10,000 different odours were not understood. This year's Nobel Laureates in Physiology or Medicine have solved this problem and in a series of pioneering studies clarified how our olfactory system works. They discovered a large gene family, comprised of some 1,000 different genes (three per cent of our genes) that give rise to an equivalent number of olfactory receptor types. These receptors are located on the olfactory receptor cells, which occupy a small area in the upper part of the nasal epithelium and detect the inhaled odorant molecules.
Each olfactory receptor cell possesses only one type of odorant receptor, and each receptor can detect a limited number of odorant substances. Our olfactory receptor cells are therefore highly specialized for a few odours. The cells send thin nerve processes directly to distinct micro domains, glomeruli, in the olfactory bulb, the primary olfactory area of the brain. Receptor cells carrying the same type of receptor send their nerve processes to the same glomerulus. From these micro domains in the olfactory bulb the information is relayed further to other parts of the brain, where the information from several olfactory receptors is combined, forming a pattern. Therefore, we can consciously experience the smell of a lilac flower in the spring and recall this olfactory memory at other times.
Richard Axel, New York, USA, and Linda Buck, Seattle, USA, published the fundamental paper jointly in 1991, in which they described the very large family of about one thousand genes for odorant receptors. Axel and Buck have since worked independent of each other, and they have in several elegant, often parallel, studies clarified the olfactory system, from the molecular level to the organization of the cells.
