The gray-haired lady can't wait to leave the building to search for her dad. Unless watched, she will walk in the streets in an effort to find her father, who died 30 years ago.

    Not all cases of Alzheimer's disease look like this, but Alzheimer's is a serious disease that is said to be the fourth or fifth leading cause of death for people over age 75. It is said that about three percent of the U.S. population over age 65 have Alzheimer's. In the early stages; people may exhibit short-term memory loss. Some may experience changes in personality, easy to be angry. As the disease progresses, patients might lose the ability to move and may be unable to speak or move at all. This progressive disease generally lasts 8 to 10 years before death occurs.

    While no one is certain what causes these changes in the brain's nerve fibers, their effect is certain. Alzheimer's destroys not only the patients, but also spouses（配偶）, friends and families.

    What should you do if you notice progressive memory loss in yourself or a loved one? Have the person examined by a doctor who is a specialist in the treatment of Alzheimer's disease. Though many reasons other than Alzheimer's disease may cause memory loss, its early diagnosis（诊断）and treatment may delay some of the most serious effects.

    What feeling will you likely experience if a loved one suffers from Alzheimer's disease? A person will often go through the various stages of sadness, shock, anger, and so on. If the spouse develops the disease, you may experience hurt and disappointment when he or she doesn't remember you are married.

    Life for the Alzheimer's patients and their loved ones will never be the same as the disease progresses, bringing a deep sorrow, loss and even anger towards God. No matter what feelings are present, facing them honestly will serve one better than burying them.

    Billie Holiday was an American jazz singer and songwriter. Nicknamed Lady Day by her loyal friend and musical partner, Lester Young, Holiday had a great influence on jazz and pop singing. Her voiced style, strongly inspired by jazz instrumentalists, pioneered a new way of controlling tempo (节奏). Above all, she was admired for her deeply personal and direct approach to singing.

    She co-wrote a few songs, and several of them have become jazz standards, notably God Bless the Child, Don't Explain, and Lady Sings the Blues. She also became famous for singing jazz standards written by others, including Easy Living and Strange Fruit.

    Her early career is hard to track down with accuracy. But she later gained work singing in local jazz clubs before being spotted by a talent scout (星探), John Hammond in 1933.

    Her voice and recordings were loved for the depth of emotion and intensity she could bring to classic standards. Her range of voice was not the greatest, but her extraordinary low rough voice was soon to become very famous and influential.

    She was an important icon (偶像) of the jazz era and influential in the development of jazz singing. In the late 1930s, she began singing a civil rights song called Strange Fruit, a song which told the tale of a lynching (用私刑处死) of a black man in the Deep South. It was very controversial for that period and it was not played on radios. It was recorded for Commodore Records and she performed it many times over the next 20 years.

    Billie Holiday had a difficult upbringing which influenced her attitude toward life. She experienced many violent relationships. She also became increasingly dependent on various drugs which contributed to her early death in 1959, aged just 44.

    Harvard University in the United States has been ranked as the university with the best “reputation” in the world.

    The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say, the list measures how universities are regarded, rather than how they actually performed.

    “A subjective, word-of-mouth (口碑的) quality such as “reputation” has genuine economic value for universities,” said Simon Marginson, professor of higher education at the University of Melbourne in Australia.

    “Reputation is not just an impression, though it might not be as reliable as performance by objective indicators (客观指标),” said Prof Marginson.

    Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which dominate this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth.

    “For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness,” said the president of Cambridge University's students' union, Rahul Mansigani.

    “Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge,” he said.

    Do you ever wonder why trees begin to bud (发芽) earlier in some cities? Scientists finally found the answer but it's not very pleasant. New science suggests a relationship between light pollution and the timing when trees produce buds, which signals the arrival of the spring season.

    Light pollution is defined by the Lighting Research Center as the unwanted consequence of outdoor lighting such as street lights. Excessive (过多的) man-made light at night results in disturbed natural cycles, and also prevents the observation of stars and planets at night. But its effect on the environment goes beyond that.

    By studying some trees, researchers found out that trees that are more exposed to artificial lighting at night bud up to 7.5 days earlier than those at the natural nighttime setting. And they found out that light had a more significant effect than temperature when the buds came out. The early budding may cause problems for insects, which feed on leaves, and the birds which then feed on them in turn. Professor Richard, who helped lead the research, explained that more than the budding of trees, the study implies the danger to the balance of the ecosystem. “At the moment, caterpillars (毛毛虫) are timed to hatch to make the most of the opportunities to feed on freshly budded leaves, and birds hatch in time to feed on the young caterpillar,” he said.

    Migratory (迁徙的) birds are also negatively affected by light pollution. The glare might confuse them and make them lose their flying sense. The phenomenon might explain why some birds accidentally knock into buildings.

    Such results stress the need to pursue studies that aim to measure the effect of light pollution. If the issue were left to continue, it is estimated that by 2100, spring would begin almost a full month earlier than it does today.

    Many of us love July because it's the month when nature's berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia's fields are little powerhouses of nutritional protection.

    Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.

    When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat "ice cream". For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.

    If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a "soft-serve" creamy dessert, to be eaten right away. This makes a fun activity for a children's party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
