LOS ANGELES, June 29 (Xinhua) -- The war on cloud intensified as Microsoft Office announced its decision on Tuesday to go cloud in an attempt to compete with its immediate but not last competitor, Google Docs.Microsoft holds a virtual monopoly on office productivity software. Most computer users in the world use the Office software for word processing, spreadsheet, presentation and other purposes. However, Microsoft Office faces a strong enemy -- Google Docs, which provides cloud service, that means users do not have to purchase any software to be installed on their computers. If they go online, they can start use the application, and they do not need to worry about their files, because the files also go with the cloud, and users can get access to their files at anytime, anywhere.The cloud-based Office 365 is designed for the mobile age when people go with their software and documents.The actual features and functionality of the tools have a lot of bearing on which productivity suite users choose. The Word Web App is more visually appealing and polished than its Google counterpart, but overall the two seem roughly equivalent in features.When tested on a sample presentation in both the PowerPoint Web App and Google Docs Presentation, the PowerPoint Web App immediately presented with a diverse selection of attractive themes to choose from, but Google defaulted to plain black text on a plain white background.On slide and image, in Google Presentations, the image filled the whole slide but the PowerPoint Web App was smart enough to size the image automatically.When push comes to shove, the features of the Office Web Apps in Office 365 are pretty much the same as what Google Docs has to offer. However, Microsoft makes key features easier to get to, and works more intuitively. For users already familiar with Microsoft Office, the Office Web Apps version is easy to use.Both Office 365 and Google Docs are Web-based platforms, and they will work from any Web browser. Google Docs excels in the Chrome browser while Microsoft Office 365 works best in Internet Explorer. It makes sense that each would make sure that their online productivity tools are optimized for performance and functionality in their own browser.Collaboration in real time is the primary selling point of Google Docs, which can be shared with any other Google account. The users who share a file can all access and work with it simultaneously. Each user is assigned a unique color so users can easily identify who is making changes to what.But in the price war, Microsoft can not beat Google Docs. Office 365 starts at six dollars per user per month for the Professional and Small Business plan. The Medium Business and Enterprise plans range from 10 to 27 dollars per user per month. But the Google Docs is free.Microsoft also faces a challenge on how to go cloud while still keep the computer-based Office software.Statistics showed that nearly nine of every 10 office computers runs one of the 14 versions of Office the company has released since the software's launch in 1989. The company now needs to convince those computer users, estimated at about one billion, to switch to Office in the cloud without disrupting the legacy version that is financing the transition.The growing cloud market is profitable. The International Data Corp. projected the market for cloud-computing services and software is expected to grow more than 27 percent annually over the next five years and reach 73 billion dollars by 2015.It is estimated that by 2015 one of every seven dollars spent on technology will be connected with cloud computing and the winners of the cloud platform wars will likely be the new power brokers of the IT industry.It is reported that Salesforce.com has added a communication technology called Chatter to its service to allow clients to communicate within its sales management cloud service. Amazon's Elastic Cloud has attracted enterprise customers because of its ability to scale up capacity to match peaks in client demand.By 2015, it is estimated that software-oriented cloud services will account for roughly three-quarters of all spending on public cloud services.

BEIJING, Aug. 24 (Xinhuanet) -- Married patients are more likely than single ones to survive 15 years after heart surgery, according to a study online in the Health Psychology.Researchers of the study tracked 225 people who underwent coronary bypass surgery from 1987 to 1990. They found that 124 patients of them, or about 55 percent, survived for at least the next 15 years. And 61 percent of the married patients and 30 percent of the unmarried survived.Kathleen King, lead author of study, said that the close connection to another person in a marriage lengthened patients’ lives."Marriage gives you purpose in life, and feeling like you have a reason to live is an important part of doing the things you need to do to stay alive," Harry T. Reis, co-author of the study, said. "Married people also help each other; remind each other it's time to take their pills. And they probably eat healthier."However, the marriage quality had different effects on the survival odds between men and women. Men who had bypass surgery lived longer by virtue of simply being married, regardless of how happy or miserable the union, but the marriage quality had more impact on women's survival after surgery. 83 percent of the happily married women had survived, compared with 28 percent of the less happily married women and 27 percent of the single women. Among the men, 83 percent of the happily married were still alive, compared with 60 percent of the less happily married and 36 percent of the single."The most dramatic thing to me is [that] just being married, especially if you had a happy marriage, had that big an effect 15 years later," King told ABCNews.com.Marriage does not only have a positive effect on the survival of patients after heart surgery, but also benefits patients with other diseases.In recent years, a number of studies have showed several apparent health benefits of marriage. For instance, it might slightly add the odds of survival from colon cancer and help reduce pain in rheumatoid arthritis patients.

New York, Sept. 23 (Xinhua) -- A Chinese scientist was presented a prestigious U.S. award on Friday for the discovery of artemisinin, a drug therapy for malaria that has saved millions of lives across the globe, especially in the developing world.Pharmacologist Tu Youyou, 81, became the first scientist on the Chinese mainland to win Lasker Award, known as "America's Nobels" for their knack of gaining future recognition by the Nobel committee.Tu, a scientist at the China Academy of Chinese Medical Sciences in Beijing, pioneered a new approach to malaria treatment that has benefited hundreds of millions of people and promises to benefit many times more. By applying modern techniques and rigor to a heritage provided by 5000 years of Chinese traditional practitioners, she has delivered its riches into the 21st century."Not often in the history of clinical medicine can we celebrate a discovery that has eased the pain and distress of hundreds of millions of people and saved the lives of countless numbers of people, particularly children, in over 100 countries," Lucy Shapiro, a member of the award jury and professor of Stanford University, said while describing Tu' s discovery.Shapiro said the discovery, chemical identification, and validation of artemisinin, a highly effective anti-malarial drug, is largely due to the "scientific insight, vision and dogged determination" of Professor Tu and her team. She thought Professor Tu's work has provided the world with arguably the most important pharmaceutical intervention in the last half century."The discovery of artemisinin is a gift to mankind from traditional Chinese medicine," Tu said while receiving the award. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world."

WASHINGTON, July 5 (Xinhua) -- Intake of high levels of folate, a water-soluble B vitamin that occurs naturally in food, may reduce colorectal cancer risk, according to a new study published Tuesday in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. "We found that all forms and sources of folate were associated with lower risk of colorectal cancer," said lead author Victoria Stevens, of the American Cancer Society. "The strongest association was with total folate, which suggests that total folate intake is the best measure to define exposure to this nutrient because it encompasses all forms and sources."Total folate includes naturally occurring food folate and folic acid from fortified foods and dietary supplements.The research team investigated the association between folate intake and colorectal cancer among 99,523 participants in the Cancer Prevention Study II Nutrition Cohort; a total of 1,023 participants were diagnosed with colorectal cancer between 1999 and 2007, a period entirely after folate fortification began. Neither higher nor lower risk was observed during the first two years of follow-up (1999 to 2001), while associations were statistically significantly inverse for the subsequent years (2002 to 2007). The findings of this study add to the epidemiologic evidence that high folate intake reduces colorectal cancer incidence.Folates are essential nutrients needed to make components used for functions required for normal cell growth, including DNA synthesis and repair. Because these processes are critical for cell growth and differentiation, the relationship between folate intake and cancer development has been investigated in several cancers, and most extensively in colorectal cancer.

RAMALLAH, Aug. 26 (Xinhua) -- China's special envoy to the Middle East, Wu Sike, said here Friday that his country fully supports the Palestinians' right to establish an independent state in a balanced manner and through peace talks."China supports the Palestinian people and their cause. We also support the Palestinians to get the United Nations recognition of a Palestinian state on the lands occupied in 1967 with Jerusalem as capital," he told Xinhua in Ramallah.The envoy said peace talks with Israel are the best way to reach a settlement, adding that gaining UN recognition is not an alternative to peace negotiations.China supports a two-state solution -- Israel and an independent Palestinian state living side-by-side in peace and security, he said, noting that he believes the current developments in the Middle East have a positive impact on the Palestinian cause."The Middle East witnesses many changes. People have many chances to participate in political life. The Palestinian cause is a main issue that attracts the attention of the Arab people," he said."The recent meeting of the Arab League Peace Initiative Follow- Up Committee in Qatar assures the Arabs' support to the Palestinians' bid for full UN membership," he said. "This will help the Palestinians gain more international support."The Palestinians say they will approach the UN in September to get full membership of the world body as peace talks with Israel have long been deadlocked, a move disapproved by Israel and the United States.Wu expressed his appreciation of the reconciliation deal signed between Palestinian National Authority President Mahmoud Abbas' Fatah party and Hamas movements in Cairo in May."This move will help the Palestinians to have more countries on their side," he said.Wu said his Middle East tour was taking place at an important moment as the region is witnessing crucial changes, stressing that China respects the choices of the peoples."The Arab peoples are able to make their own decisions toward development," said the envoy.He also said the ties between China and the Arab countries are based on strong foundations, regardless of the changes taking place in the region.Wu met with Palestinian President Mahmoud Abbas and other officials Tuesday, the first day of his ongoing Middle East tour.This was Wu's second visit to Palestinian territories this year, after which he will travel on to Israel, Egypt and France.
