BEIJING, Oct. 14 (Xinhuanet) -- Materialism could be harmful to marriage, according to a new study published in the American Journal of Couple & Relationship Therapy Thursday.The researchers collected online "relationship assessment" questionnaires from 1,734 U.S. married couples.The questionnaire covered the topics about the couples' marital satisfaction, conflict patterns, marital communication, and marriage stability, and so on.Non-materialistic couples were about 10 to 15 percent better than those materialistics in their marital satisfaction, marriage stability and conflict levels, according to the study."What we found was a general pattern that materialism seems to be harmful to marriage," said study researcher Jason Carroll, a professor of family life at Brigham Young University.It didn't matter whether the materialistic spouse was the man or the woman, he added.However, materialism is not simply black-or-white: some couples can pursue their fortune and keep their relationship strong at the same time, the researcher suggested.But breaking their materialistic thought would be helpful for most couples, Carroll concluded.

BEIJING, Oct. 20 (Xinhuanet) -- British scientists used bacteria and DNA to build basic components for digital devices in a new research, according to media reports, suggesting biological computers come closer to reality.Digital devices are based on logic gates, fundamental building blocks in silicon circuitry, said Professor Richard Kitney, leading researcher of the research published in the journal Nature Communications, "Without them, we could not process digital information."According to Science Daily, Professor Kitney and his colleagues from the Imperial College London replicated the building blocks using bacteria and DNA, forming biological logic gates, which paved the way for building more complex biological processors in the future.The researchers hoped biological computers can be applied to monitoring human health in the future.They believed that small biological processors, inserted in human bodies, could roam inside the bodies, monitor the health, and correct any problems they found.These biological logic gates are the most advanced created by scientists. But there is still a long way to go to apply them in reality, said Professor Kitney.

BEIJING, Nov. 17 (Xinhua) -- The Beijing municipal government Thursday launched a news release platform on Sina's weibo.com, China's popular Twitter-like microblogging service.Twenty municipal government agencies will post newly-unveiled policies and regulations, work developments, and information of news conferences on the joint microblog account, said Wang Hui, head of the Beijing municipal government's information office.The government departments will also timely answer hot topics and social concerns, Wang said.Many government departments have their own microblog accounts. The municipal public security bureau, for example, opened its microblog in August last year and now has over 1.8 million followers."I'm happy I can communicate directly with the government. And I hope my viewpoints and suggestions can get attention," said weibo user 1910060523.Many, however, question the move. "Is it really the case that everything can be said here and the government will read the comments and give responses?" said another user.Wang Hui said, "We are not just making a show. We shall be sincere to answer public's concerns over hot topics."

SHIJIAZHUANG, Oct. 16 (Xinhua) -- Chinese archaeologists said Sunday that they have found evidence of the cultivation of glutinous millet in the northern province of Hebei that could date back to 10,000 years, the earliest evidence of people growing the crop in the world.Lab results showed that remains of glutinous millet found at archaeological sites in Cishan Village in the city of Wu'an were harvested during the Neolithic Era between 8,700 to 10,000 years ago, scientists with the Institute of Geology and Geophysics of China Academy of Sciences (IGGCAS) said at a cultural festival held in Wu'an on Sunday.This means Cishan was the birthplace of the crop, archaeologists said.They have also found remains of foxtail millet in the pits, which could date back to between 8,700 and 7,500 years. This would be the earliest evidence of the crop's cultivation, which means that Cishan was the birthplace of foxtail millet, too, said Lu Houyuan, an IGGCAS scientist.Cultivating small-seeded dry crops was more prevalent than cultivating rice in prehistoric times, especially in China's semi-arid northern regions, Lu said.A total of 50,000 kilograms of grains have been stored in 88 pits for thousands of years at the Cishan Site, a Neolithic site discovered in 1972.In addition to grain remnants, pottery, stone tools, animal bones and bone artifacts have also been excavated from the site, which archaeologists believe will help their research in the emergence of agriculture in China.
