SAN FRANCISCO, July 6 (Xinhua) -- Facebook on Wednesday introduced a new video calling feature powered by Skype and some improvements to the chat designs on the social networking site.According to Facebook, users can reach video calling from a new "Call" button on a friend's profile or from the chat panel after downloading a Skype application. A recipient will receive an alert that they are being called and can then accept or decline.At the press event held at Facebook headquarters in Palo Alto, California, CEO Mark Zuckerberg said the feature will begin with one-on-one video chat. Skype CEO Tony Bates, whose company has been acquired by Microsoft, said Skype is considering having its paid product within the Facebook product.The social networking company also introduced "Ad Hoc Group Chat", which enables users to start a group chat instantly without creating a group with those multiple friends at first. The new group chat feature is also available for Facebook's mobile interfaces.Facebook also introduces a sidebar that lists the people a user messages most, enabling users to chat with close friends, professional contacts or co-workers without being interrupted. The sidebar can adjust with the size of users' browser window and automatically appears when the window is wide enough.In the opening remarks at the press event, Zuckerberg confirmed that Facebook had surpassed 750 million monthly active users. He said the company had declined to announce the number earlier because it has become focused on other metrics, like how actively users are sharing information.The CEO said users are now sharing 4 billion "things" on Facebook every day, which grew at an exponential rate compared to the amount users share a year ago."Social networking is at an inflection point," said Zuckerberg, adding that he believes social networking now is more about the strength of connecting people rather than the quantity of users or ubiquity of the technology.Zuckerberg presented a graph to show how Facebook product launches have helped drive the growth of sharing. He said the social network expects more innovations from other companies involved in everything from music to communication to help drive the growth.

He also said that China's track record of sharing knowledge with the World Bank was creating a "catalyst for consensus" and that placed the institutions in good stead to benefit from China's economic consistence."The Chinese policy mix includes a tool box of administrative measures ... In general, one of the lessons that the United States and others can learn (from China) is that to have supervisory policies for bank regulatory systems can be a useful part of the tool set."Aside from hinting that over-heating global real estate markets could benefit from China's regulatory tightening, Zoellick suggested if China moved to more market-exposed decision making, he hoped China's bank regulators would not step too far back."Over time China will be better served to move to more precise and market signals than more administration-based decisions. Over time China will want to move to more market based decisions ... but I don't want this to be interpreted that supervisors don't have to supervise," he said.

YANGON, July 10 (Xinhua) -- Myanmar is projecting to build the first-ever liver transplant hospital in line with the international standard, the local weekly Voice reported Sunday.With the technological help of the Changi General Hospital of Singapore, a 40-million-U.S dollar worth private hospital has started building since late last month.The hospital will offer services for the patients living with heart and kidney diseases and for protection from being affected Methicillin-Resistant Staphylococcus Aureus (MRSA), the report said.In Myanmar, liver transplant will cost about 20 million Kyats ( 25,000 U.S. dollars), lesser than other countries, the report added.Myanmar experts carried out successful liver-transplant operation in 2004 for the first time and in 2009 for the second time.

SAN FRANCISCO, June 8 (Xinhua) -- Facebook Inc. will be probed by European Union (EU) regulators over its latest facial recognition feature rolling out worldwide, U.S. media reported on Wednesday.The feature, called Tag Suggestions, uses face recognition software to match users' new photos to other photos they are tagged in. It groups similar photos together and suggests the name of the friend in the photos.Facebook rolled out the feature in the United States late last year, where users can opt out of the feature by going to their private settings. But Facebook switched it on by default without telling users first when it became available on Tuesday in countries outside of the United States.A group of privacy watchdogs from 27 EU nations will study the measure for possible rule violations, a Luxembourg official of Article 29 Data Protection Working Party told Bloomberg. The Working Party, an independent EU advisory body on data protection and privacy, comprises the data protection regulators of all the 27 EU member states."Tags of people on pictures should only happen based on people' s prior consent and it can't be activated by default," said the Luxembourg official, Gerald Lommel. He noted that such automatic features "can bear a lot of risks for users" and the European data- protection regulators will "clarify to Facebook that this can't happen like this."Authorities in Britain and Ireland said they are also looking into the new function on Facebook. The British Information Commissioner's Office told Bloomberg that "the privacy issues that this new software might raise are obvious," saying it is "speaking to Facebook" about the issue.Facebook has been under scrutiny by EU regulators for several privacy concerns, such as users' default settings and how the company uses the information collected from its social network website.

SAN FRANCISCO, Sept. 13 (Xinhua) -- Researchers in San Francisco, U.S. have found in a latest study that bisphenol A (BPA) and methylparaben, two chemicals commonly used in consumer products, can interfere with the breast cancer drugs, local media reported on Tuesday.In the study, doctors from California Pacific Medical Center in San Francisco found that healthy breast cells from high-risk patients started to find ways to bypass breast cancer drugs after they were exposed to BPA and methylparaben in the lab.The cells exposed to the two chemicals kept growing and didn't die after they were introduced with Tamoxifen, a current standard drug therapy for female breast cancer and most common used treatment for male breast cancer, Dr. William Goodson, lead author of the study, told San Francisco Chronicle.Goodson said that BPA and methylparaben not only mimic estrogen 's ability to drive cancer, but appear to be even better than the natural hormone in bypassing the ability of drugs to treat it. The finds have been published online in the British medical journal Carcinogenesis.The research shows more evidence of safety issues of BPA, a chemical primarily used to make plastic baby bottles, food containers, household electronics and etc, as well as the less known methylparaben, a chemical preservative used in cosmetics and other personal care products.The researchers noted that the breast cancer rates have been growing by about the same amount in men as in women over the past three decades. Scientists have been looking at environmental causes for the disease and wondering where the hormones are coming from.Goodson said BPA and methylparaben are used so widely and even found in household dust, noting that it is still unknown whether the effects of exposure to the chemicals are reversible.Since 2008, several governments issued reports questioning the negative health effects of BPA, especially raising concerns regarding exposure of fetuses, infants and children. BPA use has been banned in baby bottles in a lot of countries and regions.As for methylparaben, the U.S. Food and Drug Administration said on its website that "at the present time there is no reason for consumers to be concerned about the uses of cosmetics containing parabens (including methylparaben)."
