Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure.
Dr. Scott Small is a professor of neurology at Columbia University in new York City He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memorytests.
The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four .year study involving 18,000 adults. This study will use flavones capsules(胶囊) The study subjects will be divided into two groups and will take two pills per day. The capsules used will all Look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo
Dr. Manson says it's not necessary for people to start eating more chocolate, because 3 person would have to eat a huge amount of chocolate to get the same level of flavones given to the Lest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarity, Dr. says a cocoa-based flavones extract（提取）may be developed in the future But he says that more studies are needed to see how much flavones is good for our health

People in the western state of California who are in the United States illegally can now request a driver's license. The law went into effect on January l. California is not the first American state with such a law, but it has the largest number of illegal immigrants. More than a million people began to request licenses shortly after the new state law went into effect. Among them was Christian Alvarado. Mr. Alvarado entered the United States from El Salvador eight years ago without permission from the U.S. government. Some call such people "illegal immigrants." Others call them "undocumented immigrants "
Mr. Alvarado thinks is so exciting, for be has been waiting for the license for a long time. But some are worried that their personal information will be used to find them and deport them. Armando Botello is a spokesman for the California Department of Motor Vehicles, or DMV. He says people should not be afraid, for such information will not be shared.
The new licenses are the same as licenses given to citizens except that they have the words "Federal Limits Apply". That means the license cannot be used to travel on an airplane or enter a federal building. Ana Garcia, working at the Central American Resource Center, says some illegal immigrants fear those words will be used to abuse them. Civil rights groups say the police and others
Dan Schnur , a political scientist at the University of Southern California, said that the main argument against the new law is that it rewards illegal behavior. But Professor Schnur argued that young, white Americans generally support immigration reform, including giving driver's licenses to illegal immigrants
"It's simply because they grew up a much more multicultural society than their parents or their grandparents did:" Professor Schnur says he believes the changes in beliefs about illegal immigrants that have taken place in California will spread throughout the United States.

The 115m Christmas Bird Count is officially underway. The count is an annual investigation of local and migratory(迁徙的)birds and it's organized by the National Audubon Society. From December 14 to January 5, volunteers will gather in more than 2,000 locations in North, Central and South America to count the birds in their area.
Each count takes place in a circle about 24 kilometers wide. The volunteers follow specific routes within the circle and record the number of individual birds and the different species they see there in a single day. The results are sent to the National Audubon Society and later published on Audubon's Christmas Bird Count website. The data collected during the bird count is a key source Of information for ornithologists, scientists who study birds.
This information is used to develop conservation programs to protect bird habitats and the environment /n general. Data from the bird count was also used to determine that three species-the Western screech owl, the rusty blackbird and the Newfoundland red crossbill - should be added to Canada's list of species at risk.
The annual bird count was created to protest another Christmas tradition at the very beginning .in the United States in the 19th century, people would often hold "side hunts" on Christmas Day.
Teams of hunters would compete to see who could kill the most birds or other animals that day. In December 1900, Frank Chapman, an American ornithologist, suggested that instead of hunting birds, people should count them.
Twenty-seven people in 25 locations joined in the first Christmas bird count Last year, more than 70,000 volunteers took part. This year, counts are scheduled to take place in 17 countries, ranging from the Arctic to the Antarctic, with most located in Canada and the United States .instead of taking place only on Christmas day, counts are now held on different days for different areas.
