WELLINGTON, May 31 (Xinhua) -- New Zealand agricultural produce regulators cleared an Auckland-based firm that exported infant formula to China of food safety concerns, just hours after confirming they had launched an investigation.The clarification came the same day Kiaora New Zealand International, marketers of Heitiki infant formula, apologized for using a Maori name and icon on its product packaging.The Ministry of Agriculture and Forestry (MAF) issued a statement Tuesday to say Kiaora New Zealand had been cleared of food safety and export regulations concerns, but an investigation into the labeling and marketing of Heitiki would continue.The MAF issued a statement earlier Tuesday confirming reports it was investigating the product's safety, but MAF compliance and enforcement director Geoff Allen said in a later statement the investigation had been underway for about 10 days."The investigation was triggered by our internal surveillance. The investigation was primarily on whether there was a food safety issue, and I'm pleased to report that no food safety issues were identified," said Allen.Nothing "untoward" was identified in the origin and export destination of Heitiki-branded products, which were manufactured in New Zealand according to legal requirements, said Allen."The investigation has now turned to the labeling and marketing of the product. This aspect is ongoing, and seeks to identify anything in the labeling or marketing that is inaccurate or misleading.

BEIJING, Aug. 12 (Xinhuanet) -- Engineers at the University of Illinois have unveiled novel, skin-mounted electronics whose circuitry bends, wrinkles, and even stretches with skin, according to media reports quoting the Science Friday.The device platform includes electronic components, medical diagnostics, communications, and human-machine interfacing on a patch so thin and durable that it can be mounted to skin much like a temporary tattoo, the jounral described.What's more, the engineers demonstrated the invention across a wider range of components, including LEDs, transistors, wireless antennas, sensors, and conductive coils and solar cells for power."We threw everything in our bag of tricks onto that platform, and then added a few other new ideas on top of those to show that we could make it work," said engineering professor John A. Rogers in a news release.

BEIJING, Aug. 24 (Xinhuanet) -- Facebook said it is overhauling its privacy settings to give members easier, more precise control over who sees posts, photos and other content over the vast social network.Starting Thursday, Facebook is rolling out new privacy tools that are placed with each piece of content, replacing options that are now buried in overall account settings.Privacy has been a consistently sticky problem for the Palo Alto firm, which has felt the heat from privacy advocates and government regulators. And recently, Facebook faced stiffer competition from Google's new Google+ social network, which was hailed for including a "circles" feature with easy-to-use privacy settings.Instead of vague labels such as "everyone," which have been mistaken for a Facebook member's social network instead of anyone on the Internet, the new system will include more precise words such as "public.""You have told us that 'who can see this?' could be clearer across Facebook, so we have made changes to make this more visual and straightforward," Chris Cox, Facebook's vice president of product, said in blog post."The main change is moving most of your controls from a settings page to being inline, right next to the posts, photos and tags they affect. Plus there are several other updates here that will make it easier to understand who can see your stuff (or your friends') in any context," Cox said.While privacy advocates reserved judgment until the new settings are actually released, they were optimistic the changes will benefit consumers."These changes do make me feel very confident in the direction that Facebook is going and the way they are thinking about privacy," said Erica Newland, policy analyst for the Center for Democracy & Technology in Washington, D.C.

CAIRO, July 6 (Xinhua) -- Egypt's Central Administration of Agricultural Quarantine has denied again that the country's fenugreek seeds exported to Europe caused the E.coli infections which have claimed dozens of lives.The Egyptian authorities took and analyzed fenugreek seeds samples from the warehouse of the said Egyptian exporter and all results were negative by the strain, a statement posted on the official website of Egypt's Agricultural Ministry said on Wednesday."E.coli strain has not been reported in Egypt and no illness cases have been found," it added.If fenugreek seeds sprouts are suspected to be contaminated with E.coli pathogenic strain, it could be related to different handling processes, such as the re-packing or water used for sprouting, the statement said.The European Union (EU) on Tuesday agreed to ban the import of certain types of seeds from Egypt as Egyptian fenugreek seeds were reported to be linked with the outbreak of E.coli in Europe.The European Food Safety Authority (EFSA) published early Tuesday a report from its task force on the E.coli outbreaks in Germany and France, indicating that fenugreek seeds imported from Egypt is the most likely source of the outbreaks.The E.coli outbreak has killed over 50 people in Europe since it was first reported in late May.Russia's food safety watchdog Rospotrebnadzor has also banned the import of certain types of produce from Egypt over food safety concerns, a Russian official said on Wednesday.Egypt's Ministry of Agriculture refuted the claims of Egypt being the source of E.coli Friday.

BEIJING, Aug. 22 (Xinhuanet) -- Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday.An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm.As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive.Scientists and doctors know that a sperm identifies an egg when proteins on the head of the sperm match and bind to a series of specific sugars in the egg’s outer coating. With a successful match of proteins, the outside surfaces of the sperm and egg then bind together before merging, which is then followed by delivery of sperm’s DNA into egg.To identify this molecules, the researchers used ultra-sensitive mass-spectrometric imaging technology to observe and identify which molecules are most likely to be key in the binding process.They experimented with a range of synthesised sugars in the laboratory and found that it is SLeX that specifically binds sperm to an egg.According to the World Health Organisation, infertility affects about 15 percent of reproductive-aged couples around the world and almost one in every seven couples in Britain has problems conceiving a child for various reasons.
