What makes the sea tum red and causes thousands of fish to die？As far back as anyone could remember，the blame was placed on the "red tides. " In 1947，scientists finally connected the red tides with a microscopic sea organism（有机体）1.（call）the dinoflagellate.
The dinoflagellate is so tiny 2. 6，000 of these organisms may be contained in 3. single drop of water. It stands on the borderline between plant and animal in its clasification. it produces its own food，as plants do. But it moves 4.（free）and eats other organisms，as animals do.
Dinoflagellates are normally only one of the many kinds of organisms found in plankton. Plankton is the name given to all very small 5.（form）of sea life. However，when the air and water 6.（be）calm and warm，dinoflagellates multiply with 7.（amaze）sped. The surface of the water appears 8.（cover）with a red carpet.
The dinoflagellates give off a poison. Many fish die. Their bodies are washed up on the beach. Beaches are not fit 9. any use. Fish that are not killed may become 10.（poison）to animals or people who eat them. Commercial fishing comes to a stop.
As dinoflagellates consume all the food and oxygen in an area，they die. After a time，the sea returns to normal. But when conditions are right，the red tide comes again.

Do you like to flaunt your expensive items? You could find yourself without friends! Scientists prove that expensive status symbols make you look less socially attractive.
Items such as a fancy car and a Rolex watch are often thought to increase our social standing and often come with a high price tag(标签).According to the latest research, however, it has the opposite effect and people would prefer to be friends with someone who places less value on material objects.
“Often we think that status symbols will make us look more socially attractive to others, “says Stephen Garcia, the study's lead author from the University of Michigan. He adds, “However, our research suggests that these status signals actually make us look less socially attractive.
The researchers conducted six studies which assessed how people presented themselves and how people viewed strangers. People who chose to wear higher status items tended to get a negative response, but people wanted to be friends with people who preferred lower status symbols.
The study took the role of the luxury item to see if it was possible that the expensive item itself played a part in people's reactions. The definition of a status symbol changed based on a person's socioeconomic status, but the same effect of keeping off potential friends was seen regardless of social position.
"At a social level, we may be wasting billions of dollars on expensive status symbols that finally keep others from wanting to associate with us, "says Kimberlee Weaver Livnat at the University of Haifa. She says, "And to the extent that close friendships are important to well-being, we may be unintentionally hurting ourselves.”
However, Patricia Chen of the National University of Singapore said this does not necessarily mean status symbols are a bad thing. She says, "Our findings right now only apply to the formation of new friendships, Status symbols may be beneficial at other times and in other settings, such as when trying to establish new business contacts.”

Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.
Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.
But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.
For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.
“Even a modest amount of steps is associated with lower death rates, "said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.
The study had a few limitations. For example, the researchers only measured women’s movements once, at the start of the study period. It is possible that the women’s behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.
“Any walking is better than nothing, " Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.
