Q: Article: Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of "moderate" quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Q: Article: We all enjoy the colors of autumn leaves. Did you ever wonder how and why a fall leaf changes color? Where do the yellows and oranges come from? To answer those questions, we first have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. They take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose, which is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis, which means " putting together with light. " A chemical called chlorophyll helps make photosynthesis happen. Chlorophyll is what gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small a-mounts of these colors have been in the leaves all along. Covered up by the green chlorophyll, we just can't see them in summer. The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves. It is the combination of all these things that make the beautiful colors we enjoy in the fall.

Q: Article: How many historic churches, pubs or buildings are there in your city? Are there worth preserving? Or are they just a waste of space? There are arguments for and against spending money on historic buildings. Dangerous staircases. Uneven floors. A lack of IT infrastructure. The problem with many old buildings is that they're... old - and extremely expensive to modernize. Take the case of the Combination Room in Cambridge University. It was built in 1347 and was initially used for lectures. Later, it became the Regent House - the university's parliament. It's of enormous historical value and cultural interest. However, it doesn't meet accessibility standards for disabled people. As a result, a lift needs to be installed, but not everyone is happy about this. "Noting will persuade me that this lift would not in its effect, be a substantial alteration to the most precious room in the university. It would destroy the symmetry of that beautiful room," said one user. In general, modern buildings don't have this type of problem. They can be built according to the latest environment standards, with draught proofing and insulation to help reduce carbon emission and save energy. They can also be made wheelchair accessible, and they can be designed to ensure maximum comfort and space. Anyone who's been to a modern cinema, theatre or concert hall recently may understand the difference between the new buildings and older ones, which tend to have smaller seats, less space and poorer acoustics. Very often, there's money to be made by knocking down old building... especially if they're in city centers. So, the biggest threat to many historic buildings comes from developers. One of Croydon's oldest pubs, The Rose and Crown, is a perfect example of this. A property development company has recently been granted permission to convert the 18th century building into flats, much to the disappointment of many local residents. "The bar is full of unique features and perfect examples of a traditional London pub. It really would be truly tragic for this Grade II listed building to be turned into soulless flats," said a spokesperson for English heritage. So, are these buildings really worth preserving? "Traditional buildings such as churches, town halls, schools and hospitals give England its character," the spokesman added. " _ "[(<<>> 20116 "Building Bash")]
