BEIJING, May 4 (Xinhuanet) -- No formalin has been found in the milk powder imported from S. Korea into China due to different milk sources, the general agency of South Korea's Maeil Dairies said Tuesday.The declaration came after Maeil Dairies, South Korea's third-largest dairy company, was found to have produced milk from cows given feed tainted with formalin.The agency said that the milk used in the dairy products exported to China comes from New Zealand, Europe and other places outside South Korea, so Chinese consumers should have nothing to worry about.Formalin, a liquid form of formaldehyde gas, was largely used in the past as a disinfectant, pesticide and bactericide for preservation of biological specimens.Its use has dwindled over the years due to health concerns.After the incident, South Korea has decided to conduct emergency inspections on milk sold in the market by four major dairy companies, to check the presence of formalin.

SAN FRANCISCO, March 22 (Xinhua) -- Apple Inc. on Tuesday announced that iPad 2, the second-generation of its popular tablet computer, will be available in China's Hong Kong, Korea, Singapore and additional countries and regions in April.The company also confirmed that iPad 2 will go on sale in 25 countries on March 25 in addition to the United States, where the device first hit market on March 11 and has seen strong demand."While competitors are still struggling to catch up with our first iPad, we've changed the game again with iPad 2," Steve Jobs, Apple's chief executive officer, said in a statement."We're experiencing amazing demand for iPad 2 in the U.S., and customers around the world have told us they can't wait to get their hands on it. We appreciate everyone's patience and we are working hard to build enough iPads for everyone," he noted.Apple had planned to released iPad 2 in Japan on March 25, but delayed the launch in the aftermath of the catastrophic March 11 earthquake and ensuing tsunami in the country.The 25 countries where iPad 2 will go on sale on March 25 include Australia, Austria, Belgium, Canada, the Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Mexico, the Netherlands, New Zealand, Norway, Poland, Portugal, Spain, Sweden, Switzerland and Britain.

WELLINGTON, May 24 (Xinhua) -- New Zealand researchers have found a way to stop the growth of certain cancer tumors by " silencing" a group of PAX genes, members of a small family of genes that play important roles in embryonic development, but also allow cancer cells to grow and divide in adult tissue.In an article published in UK medical journal Oncogene, Otago University Professor Michael Eccles and colleagues revealed how they used the PAX8 gene to kill cancer cells.After detecting high levels of PAX8 protein in the majority of kidney, ovarian and thyroid cancers they studied, the researchers used molecular techniques to silence the PAX8 gene in several cancer cell lines."We found that these PAX8-depleted cancer cells ceased growing and dividing. The cells were essentially stopped in their tracks through the failure of multiple mechanisms and pathways crucial to their cell division cycle. They then entered into a state called senescence in which they no longer divided, and after that they ultimately died," Eccles said in a statement from the university Tuesday.The findings suggested that PAX8 could be a good target for the development of new cancer therapies, he said."Any resulting drugs would be a long way down the road, but in the meantime this research helps confirm that a focus on PAX genes may prove to be a fruitful line of attack against a number of cancers," he said.The research was supported by grants from the Health Research Council of New Zealand. It formed the main piece of work carried out by Otago doctoral graduate Caiyun (Grace) Li, now a postdoctoral fellow at Stanford University. Study co-authors also included Professor Antony Braithwaite and master's student Jen Nyman.In 2003, research led by Eccles discovered that proteins from one or more of the nine PAX genes were present in many common cancers. They found that "silencing" the gene expression of PAX2 in ovarian and bladder cancer cells, and of PAX3 in melanoma, led to the rapid death of the cells.

SAN FRANCISCO, April 22 (Xinhua) - Amazon's web-services disruption issues have not been completely resolved Friday morning, as some websites still in slow recovery.Amazon said in an update early Friday that meaningful progress has been made and is expected to continue over the next few hours.Reddit, a social news website, said on its homepage that "we are slowly getting our capacity back," and users may be able to log in if lucky. Some sites appeared to have recovered, including location-based social networking site Foursquare and HootSuite, an online brand management and social websites monitoring service.Amazon has not released the number of companies which have been disrupted by the outage and when the web-services will fully recover.The outage highlights risks of relying on public cloud service. Security and reliability have been experts' concerns on public could web-hosting service. Many Internet startups have been relying on the service to bring their costs down.Elastic Compute Cloud (EC2) is a central part of Amazon's cloud computing platform Amazon Web Services. It allows users to rent virtual computers on which to run their own computer applications. The European Space Agency, PBS and Ericsson are all among its cloud service customers.According to Amazon's Service Health Dashboard, errors began at 1:41 a.m. PDT Thursday in its datacenter in northern Virginia, saying "instance connectivity, latency and error rates."

BEIJING, May 14 (Xinhua) -- The uranium subsidiary of China Guangdong Nuclear Power Group (CGNPG) has said it is developing two large mines in the mainland.The two mines will be located in south China's Guangdong province and northwest China's Xinjiang Uygur Autonomous Region, according to Saturday's China Daily.The move is likely to add as much as 1,000 tonnes to the country's annual production capacity of the nuclear fuel."The two mines are expected to start operation in 2013, each with an annual production capacity of no more than 500 tonnes," the newspaper quoted Zhou Zhenxing, chairman of CGNPG Uranium Resources Co (CGNPG-URC) as saying.
