Researchers continue to show the power behind our sense of smell.Recent studies have found,among other things,that the smell of foods like pizza can cause uncontrollable anger in drivers on roads. The review explains that smell is unique in its effects on the brain.According to Conrad King,the researcher who carried out the review,"more than any other senses,the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings.This is why the smell of baking bread can destroy the best intentions of a dieter." Smell,which dictates the unbelievable complexity of food tastes,has always been the least understood of our senses.Our noses are able to detect up to 10,000distinct smells.Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000genes ,which make up an amazing 3% of the human genome.Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004for their ground-breaking research on the nature of this extraordinary sense.These two scientists were the first to describe the family of 1,000olfactory genes and to explain how our olfactory system works. According to one study in the research review,smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users.They are then more likely to speed and experience uncontrollable anger on roads.The most reasonable explanation is that these can all make drivers feel hungry,and therefore desperate to satisfy their appetites. In contrast,the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers'impatience.Similarly,the smells of lemon and coffee appeared to promote clear thinking and mental focus. However,the way genes regulate smell differs from person to person.A study by researchers in Israel has identified at least 50olfactory genes which are switched on in some people and not in others.They believe this may explain why some of us love some smells... What did Richard Axel and Linda Buck find out? A) The category of food smells. B) The logical part of human brain. C) The nature of human olfactory system. D) The relationship between food and feelings.

The Celerifere, an early version of the bicycle, was built around 1791 by a French man, Comte Mede de Sivrac. It was basically a scooter with a high seat. There were no pedals---you had to push with your feet like you do with a skateboard or a scooter. Around 1816 Baron Karl Drais de Sauerbrun in Germany added a moveable steering handle. These early machines were often known as dandy horses or hobby horses, but weren't very popular. The improvement that made them popular was added by a Scottish blacksmith around 1839. Kirkpatrick Macmillan added pedals to enable it to get up hills. It was this improvement that made the bicycle a serious form of transportation. Bike were called velocipedes or bone-shakers, because of the lack of the proper tires made for a rough ride! It wasn't until around 1869 that they began to be called bicycles ("two-wheels"). Carriage makers in Paris (either Pierre and Ernest Michaux, or their employee Pierre Lallement) switched the pedal to the front wheel. That's why it is usually either Lallement or the Michauxs, not Macmillan, who are considered as the inventor of the bicycle. In 1869 the penny-farthing or high-wheeler was invented. With the large wheel the rider could go much farther with each push of the pedal, but caused many accidents because the seat was so far off the ground. In the mid-1880s Englishman James Starley manufactured what he called the "safety bicycle" , which had two similarly-sized wheels and a major improvement--- a chain and sprocket driven rear wheel, with the pedals between the two wheels like modern bicycles. One more historical note---it's possible that the idea of the bicycle was thought of almost 400 years before it was actually invented. There is a drawing of a bicycle-like machine in one of Leonardo da Vinci's notebooks, which dates back to about 1493. Who is recognized as the inventor of the bicycle? A) The Michauxs. B) Macmillan. C) Comte Mede de Sivac. D) Baron Karl von Drais de Sauerbrun.
